2. Description of the Related Art A typical example of a conventional automatic accompaniment apparatus for obtaining an automatic accompaniment pattern desired by a user is to store a plurality of accompaniment patterns in a memory in advance and select one of them. is there. However, this method has a drawback that the selectable patterns are limited. That is, in an automatic accompaniment device of a type that selects one of pre-stored accompaniment patterns, there is a limit to the number of accompaniment patterns that can be stored. In many cases, the accompaniment pattern that the user really wants cannot be obtained.

On the other hand, as a method of making it possible to create an automatic accompaniment pattern in accordance with the user's desire, the user can manually play (key press) the keyboard of an electronic musical instrument or the like to obtain a desired pattern. Creating an accompaniment pattern and storing it in memory. Thus, the automatic accompaniment can be performed by reading and reproducing the accompaniment pattern stored in the memory. Further, in order to make the rhythm playing pattern relatively easy, a plurality of patterns are stored in advance for each individual percussion instrument sound source, and one desired pattern is selected for each percussion instrument sound source. The combination of is used to obtain the desired rhythm performance pattern as a whole.

In the latter method, the percussion instrument sound source selection operation and the selection operation for selecting the desired pattern have to be performed separately, and the operability is poor. There were some problems that had to be solved, such as the limited number of pattern variations. Further, since it is possible to select only from the patterns stored in the memory, it is impossible to freely create an accompaniment pattern. The present invention has been made in view of the above points, and provides an automatic accompaniment apparatus that enables easy creation and modification of accompaniment patterns and enables easy creation and modification of complicated patterns.

Each component is composed of a set of one or more musical instrument parts for accompaniment performance. For example, a plurality of related musical instrument parts (snare drum and bass drum, or ride cymbal and hi-hat). 2) may be classified as common components. The user can specify a desired component by operating the operator. The selected accompaniment pattern is read from the database (accompaniment pattern storage means) and stored in the temporary storage means. Therefore, the overall accompaniment performance pattern is stored in the temporary storage means by the combination of the accompaniment patterns selected for each component. The automatic accompaniment device generates an automatic accompaniment sound based on the accompaniment pattern stored in the temporary storage means.

The accompaniment pattern selected corresponding to one component is an accompaniment pattern of a set of one or more musical instrument parts corresponding to the component. Therefore, the user can select a pattern for each component from among many accompaniment patterns prepared in the database in the optimum state, so that the optimum accompaniment pattern can be obtained even if there is little musical knowledge. This is advantageous because the selection can be made. Moreover, since the selection of the pattern for one component is performed according to the operation of the operator, the selection operation is extremely simple. Due to the ease of this selection operation, it is possible to prepare a considerable number of accompaniment patterns corresponding to one component in the database and to easily select from among them. Therefore, the degree of freedom in creating and changing the accompaniment pattern can be increased.

In the automatic accompaniment apparatus according to a first aspect of the present invention, an operator for selecting a desired accompaniment pattern is composed of a component designating operator and a pattern selecting operator provided separately from the operator. There is. That is, the component designating operator is provided for each component, and a plurality of patterns in the component designated by this are selected by operating the pattern selecting operator. At this time, if the pattern selection operator outputs a continuous value such as a slide operator such as a slide operator, a rotary operator such as a wheel operator, or a multidimensional operator such as a joystick, etc. , It becomes easy to select an accompaniment pattern. Since such an operator can gradually change the output value, it becomes possible to selectively set a desired pattern from the accompaniment pattern storage means that stores an extremely large number of accompaniment patterns. Further, the accompaniment pattern storage means is composed of an accompaniment pattern storage section for storing a plurality of accompaniment patterns and an arrangement order storage section for storing arrangement order information for arranging the plurality of accompaniment patterns according to a predetermined rule, and the reading means. Alternatively, the accompaniment pattern corresponding to the operation mode may be selected by referring to the arrangement order storage unit according to the operation of the operator. As a preferred embodiment of the automatic accompaniment pattern according to claim 1, as described in claim 2, the pattern selection operator generates an operation output whose value continuously changes according to the operation. However, the reading means may select the accompaniment pattern according to the operation output. When the component designating operator is operated as described in claim 3, the pattern selecting operation at that time point is performed. The selected accompaniment pattern of the designated component may be read based on the operation output of the child.

An automatic accompaniment apparatus according to a fourth aspect is a reading means for reading out the accompaniment pattern for each component from the accompaniment pattern storage means based on the pattern selection signal output from the selection operator, and the pattern selection signal is relative. It is used as a value, and the pattern selection information for this time is created by calculating the pattern selection information from the time when the accompaniment pattern was selected last time and the value of this pattern selection signal, and the accompaniment pattern is selected based on this pattern selection information. It is what is done. That is, since the pattern selection information when the previous accompaniment pattern is selected is an absolute value, the current pattern selection information is created by adding or subtracting the relative pattern selection signal of this time. Therefore, it becomes easy to understand how much the pattern selection information when the previous accompaniment pattern is selected is different (for example, how different the patterns are in terms of complexity).

An automatic accompaniment apparatus according to a fifth aspect of the present invention relates to a predetermined accompaniment pattern in the accompaniment pattern storage means,
The setting means can be set so as not to be read by the reading means. Therefore, there is no inconvenience that the accompaniment pattern is not desired to be selected at the time of real-time automatic accompaniment, and the performance as desired by the user can be performed. As a preferred mode of implementation of the automatic accompaniment apparatus according to claim 5, as described in claim 6, the setting means stores information indicating whether or not the accompaniment pattern can be selected for a plurality of accompaniment patterns. May be.

An automatic accompaniment apparatus according to a seventh aspect of the invention is designed to specify a predetermined range in the accompaniment pattern selected by the selection operator. That is, as the predetermined range, as in the automatic accompaniment apparatus according to claim 8, a predetermined drum sound is specified from among a plurality of drum sounds constituting the accompaniment pattern, or the automatic accompaniment apparatus according to claim 9. like,
A predetermined timing range of the accompaniment pattern is designated. As described above, by being able to specify the predetermined range in the accompaniment pattern, it is possible to add or select only the favorite range, so that the degree of freedom in forming the accompaniment pattern is improved.

In the automatic accompaniment apparatus according to the tenth aspect, a predetermined drum sound among a plurality of drum sounds constituting the accompaniment pattern is replaced with another drum sound. That is, if the user likes the drum pattern but does not like the timbre, it can be replaced with another timbre. As a result, the degree of freedom in forming the accompaniment pattern is improved, and a pattern as an image can be created faster.

According to another aspect of the automatic accompaniment apparatus of the present invention, the retrieval condition designated by the retrieval condition designating means (eg,
An accompaniment pattern that matches "there are events at the second and fourth beats" or "the total number of events is n or more") is selectively read out from the accompaniment pattern storage means. This makes it possible to easily and quickly select the accompaniment pattern intended by the user. In addition,
As a preferred embodiment of the automatic accompaniment apparatus according to claim 11, as in the automatic accompaniment apparatus according to claim 12,
Each component has a selection operator for selecting a desired accompaniment pattern, and the reading means selects and reads the accompaniment pattern from the accompaniment patterns that match the search condition based on the operation of the selection operator. You may

An automatic accompaniment apparatus according to a thirteenth aspect is adapted to selectively read out an accompaniment pattern close to that input by the pattern input means for inputting a desired accompaniment pattern. This makes it possible to easily and quickly select the accompaniment pattern that the user imagines.
As a preferred embodiment of the automatic accompaniment apparatus according to claim 13, a selection operator for selecting a desired accompaniment pattern for each component is provided as in the automatic accompaniment apparatus according to claim 14. The read means may select and read the accompaniment pattern from the accompaniment patterns close to the accompaniment pattern input by the pattern input means based on the operation of the selection operator.

In the automatic accompaniment apparatus according to the fifteenth aspect, the sequential reading means reads out the accompaniment patterns from the accompaniment pattern storage means in a predetermined order. As a result, it is possible to check all kinds of patterns stored in the accompaniment pattern storage means. If you find a pattern you like, you can select it.

Generate a signal. As will be described later, the tone generator circuit 17 of the electronic musical instrument 1F is configured to be able to generate musical tone signals of various drum sounds. Any tone signal generation method in the tone generator circuit 17 may be used. For example, a memory reading method for sequentially reading tone waveform sample value data stored in a waveform memory according to address data that changes corresponding to the pitch of a tone to be generated, or a predetermined frequency using the above address data as phase angle parameter data. A well-known method such as an FM method for performing a modulation operation to obtain musical tone waveform sample value data or an AM method for performing a predetermined amplitude modulation operation using the address data as phase angle parameter data to obtain a tone waveform sample value data. You may employ suitably.

The tone signal generated from the tone generator circuit 17 is
Sound is produced via a sound system 18 including an amplifier and a speaker (not shown). The timer 19 generates a clock pulse for counting time intervals, and since this clock pulse is given to the CPU 11 as an interrupt instruction, the CPU 11 executes various processes by the interrupt process.

MIDI interface (I / F) 1D
Connects between the bus 1E of the electronic musical instrument 1F and the MIDI interface (I / F) 2C of the personal computer 20, and the MID
I interface 2C is bus 2D and M of personal computer 20
It is connected to the IDI interface 1D. Therefore, the bus 1E of the electronic musical instrument 19 and the bus 2 of the personal computer 20
It is connected to D via MIDI interfaces 1D and 2C, and bidirectional data exchange can be performed between them.

Next, the configuration of the personal computer 20 will be described. The microprocessor unit (CPU) 21 controls the operation of the personal computer 20. This CP

The OUSE I / F) 26, the switch detection circuit 27, the timer 28, and the MIDI interface 2C are connected to each other.

The ROM 22 stores various programs of the CPU 21, various data, data of various symbol characters and the like, and is constituted by a read only memory (ROM). The RAM 23 temporarily stores various data generated when the CPU 21 executes the program, and is composed of a random access memory (RAM). In this embodiment, the predetermined area of the RAM 23 is allocated to the current pattern memory area, the assign memory area, the undo buffer area, the save memory area and the pattern table area as shown in FIG.

The current pattern memory area is an area for storing a rhythm pattern read during automatic accompaniment. The assign memory area is an area for storing a rhythm pattern newly created by an edit process or a transformer process. The undo buffer area is an area for temporarily storing the rhythm pattern transformed by the transformer process. The save memory area is
This area temporarily stores the rhythm pattern of the previously existing component when the current pattern is stored when the fill-in is inserted or when the rhythm pattern of the component is read from the database.

The pattern table area is an area for storing the address of the rhythm pattern stored in the database (hard disk device 24) and the data indicating the complexity of the rhythm pattern, in the order of decreasing complexity as the address. That is, in the pattern table area, when the rhythm patterns are rearranged in the order of low complexity,
This is an area for storing a pattern table for address conversion for converting the sequential address into an address on the database. Details of this pattern table will be described later.

The hard disk device 24 is the personal computer 20.
External storage device of tens to hundreds of megabytes (MB)
It has a storage capacity of. In this embodiment, the hard disk device 24 is used as a database of rhythm patterns and is divided into three banks A, B and C to store patterns of different music styles (genres) as shown in FIG. ing.

In this embodiment, a plurality of rhythm patterns dedicated to rock music corresponding to the components of each drum sound are stored in the bank A, and a plurality of rhythm patterns dedicated to disco music corresponding to the components of each drum sound are stored in the bank B. Rhythm patterns are stored, and bank C stores a plurality of rhythm patterns common to rock and disco music corresponding to the components of each drum sound. The start address for identifying the multiple rhythm patterns stored in each bank is changed from the simple one to the complicated one in the pattern table area described above in order of address according to the degree of complexity. Remembered

For example, for a component composed of a bass drum (BD) and a snare drum (SD), BD
+ SD pattern 1, BD + SD pattern 2, ... And more complex rhythm patterns according to the pattern numbers. Similarly, TomH + TomMm + TomL pattern 1, TomH + TomMm + TomL pattern 2, ...
It becomes a more complicated rhythm pattern according to the pattern number.

FIG. 4 is a view showing the contents of the pattern table for address conversion stored in the pattern table area. In the figure, a pattern table for rock music and a pattern table for disco music are shown. The rock music pattern table has head addresses A-1, A-2, A-3, C-1, A-4, C-2 for specifying a plurality of rhythm patterns stored in banks A and C. ，
..., An in the order 1, 2, 3, ... according to the degree of complexity (magnitude of complexity) of the rhythm pattern
.., n are stored as addresses. On the other hand, the pattern table for disco music has head addresses B-1, B-2, C-1, B-3, C-2, C for specifying a plurality of rhythm patterns stored in banks B and C. −
, ..., B-n in the order of 1, 2 according to the degree of complexity (size of complexity) of the rhythm pattern
3, ..., N are stored as addresses.

Here, the first address A, B or C is
Indicates the type of bank in which the rhythm pattern is stored. That is, the start addresses A-1, A-2, A-3,
A-4 and A-n indicate addresses of bank A, head addresses B-1, B-2, B-3 and B-n indicate addresses of bank B, and head addresses C-1, C-2, and C-3 indicates the address of bank C.

As the complexity, a value obtained by digitizing a rhythm pattern into a value of "0-100" according to a predetermined rule is used. As a predetermined rule, for example, the number of sounds included in the rhythm pattern, the number of timings when note event data exists in the rhythm pattern, the number of sounds included in the first half and the number of sounds included in the second half of the rhythm pattern, and Difference, or the number of occurrences of an event at a certain timing (for example, the first beat, the third beat, the back beat of 8 minutes, etc.), is used as the complexity as it is,
The complexity is defined as a combination of these rules arbitrarily selected by the user and a comprehensive judgment of these rules. Further, the user may be allowed to rearrange the rhythm patterns arbitrarily.

In the pattern table for rock music, the address "1" stores the rhythm pattern for rock music of "5" having the smallest complexity at the head address "A-1" on the database. Shows. Similarly, for the address "2", the rhythm pattern dedicated to rock music with the complexity "7" is assigned to the head address "A-2" on the database, and the address "3" is assigned the complexity "10".
Rhythm pattern dedicated to rock music is stored at the top address "A-3" on the database, and a rhythm pattern common to rock and disco music with complexity "11" is stored at address "4" on the database. , The rhythm pattern for rock music with complexity “16” at address “5” is the first address “A-4” on the database.
In the address "6", a rhythm pattern common to rock and disco music with a complexity of "20" is stored in the first address "C-2" on the database, and in the address "n", a complex rhythm pattern of "95" is stored. It is shown that the rhythm pattern dedicated to rock music is stored at the head address "A-n" on the database.

In the pattern table for disco music,
The address "1" indicates that the rhythm pattern for disco music of "10" having the smallest complexity is stored at the head address "B-1" on the database. Similarly, the complexity of "14" is assigned to the address "2".
The disco music dedicated rhythm pattern is stored at the top address “B-2” on the database, and the address “3” is stored at the top address “C-1” of the rock and disco music common rhythm pattern of complexity “22”. ”, The rhythm pattern for disco music with the complexity of“ 25 ”is stored in the address“ 4 ”at the top address“ B-
3 ”, a lock of complexity“ 26 ”at address“ 5 ”and a rhythm pattern common to disco music at the top address“ C-2 ”on the database, and a lock of complexity“ 30 ”at address“ 6 ”. And the rhythm pattern common to disco music is at the top address "C-3" in the database, and the rhythm pattern of "91" having the highest complexity at the address "n" is dedicated to the disco music at the top address "B- n ”indicates that they are respectively stored.

Since the rhythm pattern of the bank C is common to rock music and disco music, it exists in both the rock music pattern table and the disco music pattern table. For example, in the pattern table of FIG. 4, the rhythm patterns of the head addresses "C-1" and "C-2" exist in both the rock music pattern table and the disco music pattern table. In FIG. 4, although the rhythm patterns are the same, the complexity is different because the predetermined rule for calculating the complexity is different between the pattern table for rock music and the pattern table for disco music as described above. is there. Further, as shown in FIG. 3, each bank A, B, and C also stores a fill-in pattern for real-time performance, patterns of other musical instruments, etc., so that the fill-in pattern is temporarily replaced with the current pattern. It can be inserted and played.

As shown in FIG. 3, the content of the rhythm pattern stored in each of the banks A, B, and C is a combination of timing data indicating the timing of event occurrence and note event data indicating the type of the event. Is composed by sequentially storing performance data consisting of Note that the note event data is stored here in a format corresponding to the MIDI note-on message and consists of 3-byte data. In the timing data, the interval of occurrence of each note event is represented by the number of clocks. In addition, the hard disk device 24 stores two types of sequence data as variation patterns 1 and 2 for instructing an adjective of a transformer. That is, as shown in FIG. 3, variations 1 and 2 are composed of sequential data in which adjective 1, adjective 2, adjective 3, and adjective 4 are sequentially stored.

Although not shown, a cache memory (RAM) of about several megabytes is provided or data transfer between the RAM 23 and the hard disk device 24 is performed in order to significantly reduce the access time to the hard disk device 24. It goes without saying that a DMA device may be provided to reduce the burden.

And LCD. FIG. 5 is a diagram showing a display example of the display 29. The display 29 displays the complexity of the rhythm pattern of the selected component in the selection pattern section to show which component is currently selected and at what level it is located at the complexity. There is. Therefore, it means that the component whose complexity is displayed in the item of the selection pattern is currently selected and the component in which nothing is displayed is not selected. The level of complexity of the rhythm pattern is shown according to the complexity displayed in the selection pattern section.

For example, in FIG. 5A, the bass drum (B
It is shown that the rhythm pattern of complexity “80” is selected for the component BD + SD including D) and the snare drum (SD). As for the Tom Tom component Tom, it is shown that a rhythm pattern of complexity “20” is selected. Regarding the component HH of the hi-hat, the complexity "4
It is shown that the rhythm pattern “5” is selected. As for the cymbal component CY, since there is no display of complexity, it is shown that nothing is selected. Similarly, whether or not the component is selected can be easily determined by whether or not the complexity is displayed in the item of the selection pattern. Further, it is possible to easily recognize which level the complexity of the rhythm pattern is located according to the complexity displayed in the item of the selection pattern.

Although FIG. 5A shows a case where the complexity is directly displayed as a numerical value, the present invention is not limited to this, and FIG.
The complexity may be displayed as a graphic such as a bar graph as in (B). By displaying the graphic in this way, it is possible to easily recognize whether or not the component is selected, and also to intuitively recognize the positioning in the complexity. Note that the rhythm pattern is not limited to being positioned by complexity as described above, but may be positioned by an element other than complexity (for example, severity, goodness of sharpness, etc.).
Also, a plurality of these elements may be combined and displayed in a two-dimensional, three-dimensional, or multidimensional manner. In the case of multidimensional display, a graphic display such as a radar chart is effective.

The mouse 2A is a kind of pointing device for inputting coordinate points on the display 29, and its output is a mouse interface (MOUSE I / F).

The panel switch 2B is a keyboard for inputting a program, data, etc. to the personal computer 20, and is provided with a numeric keypad, function keys and the like.

The switch detection circuit 27 detects a key operation state of the panel switch 2B and outputs key information corresponding to the operation state to the CPU 21 via the bus 2D. The timer 28 counts time intervals and generates an operation clock for the entire personal computer 20. The personal computer 20 counts a predetermined number of this operation clock to measure a predetermined time, and performs an interrupt process according to the time. For example, the personal computer 20 executes the automatic accompaniment process by setting the predetermined number to a value according to the tempo of the automatic accompaniment.

In this embodiment, a note number corresponding to the depressed state of the keyboard 1A is transmitted to the CPU 21 of the personal computer 20 through the MIDI interfaces 1D and 2C, so that the personal computer 20 can be used in addition to the mouse 2A and the panel switch 2B of the personal computer 20. Each key of the keyboard 1A of the electronic musical instrument 1F operates as an operator for selectively setting and controlling the various functions of 20.

FIG. 6 is a diagram showing an example of various functions assigned to the keyboard 1A. In the figure, the keyboard 1A is composed of a total of 61 keys, and is divided into a pattern assign area, an operator area and a drum pattern area. The keys of note numbers E0 to B1 form a pattern assign area, the keys of note numbers C2 to G # 3 form an operator area, and the keys of note numbers A3 to E5 form a drum pattern area.

The keys of note numbers E0 to B1 generate addresses corresponding to the assign memory area for storing the rhythm pattern created by the edit process or the transformer process as a new rhythm pattern. That is, the assign memory area of the RAM 23 is composed of an assign memory management area having a total of 20 addresses and a pattern storage area capable of storing 20 patterns, and each address of the assign management area is a note number. It corresponds to E0 to B1. For example, the note number E0 corresponds to the first address of the assign memory management area, the note number F0 corresponds to the second address, and so on, note numbers F # 0 to B1 correspond to the third address of the assign memory management area. To 20th address respectively. The head address value of each pattern storage area is stored at each address.

The keys of note numbers C2 to G # 3 function as various operators for performing edit processing and transformer processing. Therefore, note number C2-G
# 3 becomes the key information representing the operator function assigned to each key as it is. Specifically, the key of the note number C2 is the assign key, and the note numbers D2, E2, F2, G2
The keys A and A2 are the designated keys of the transformers 1 to 5, the key of the note number B2 is the undo designation key, the key of the note number C3 is the start / stop designation key, and the keys of the note numbers D3, E3 and F3 are the banks A to C. The designated key, the note number G3 key is a lock key for pattern confirmation, the note numbers C # 2 and D # 2 are the designated keys of variations 1 and 2, the note number F # 2 key is the replace input key, the note number. The G # 2 key is the insert input key, the note number A # 2 key is the quantize processing designation key, the note number C # 3 key is the delete drum instruction key, and the note number D # 3 key is the delete component instruction key, the note Number F # 3
Key corresponds to the accent input key, and the note number G # 3 key corresponds to the fill-in designation key. Details of the processing contents according to the operation of each of these keys will be described later.

Note number A3 in the drum pattern area
The keys E to E5 function as drum key designating keys.
Therefore, the note numbers C2 to G # 3 serve as the drum sound information representing the type of the drum sound assigned to each key. Specifically, the note number A3 key is the bass drum (BD), the note number A # 3 key is the snare drum (SD), the note number B3 key is the tom tom high (Tom H), and the note number C4 key. Is a tom tom low (Tom L), note number C # 4 key is tom tom middle (Tom M), note number D4 key is Conga high (Conga H), note number E4
Key is Conga low (Conga L), note number D # 4 key is Timbale (Timb), note number F4 key is Temple block low (TB L),
Note number F # 4 key is temple block high (TB H), note number G4 key is hi-hat close (HHC), note number A4 key is hi-hat open (HHO), note number G # 4 key Is tambourine (Tamb), note number A # 4 key is Claves, note number B4 key is Cowbell, note number C5 key is Agogou high (Agogo H), note number C # 5 The key is AgogoL, and the key of note number D5 is the hand craps (Clap).
s), the note number D # 5 key corresponds to the crash cymbal (Crash CY), and the note number E5 key corresponds to the ride cymbal (Ride CY) drum sound.

Although each of the drum sounds described above can be specified independently, in this embodiment, a plurality of drum sounds are used as a component grouped in accordance with the playing form. Therefore, one or a plurality of drum sounds make up this component. Here, in the case where the component is composed of a plurality of drum sounds, it is necessary that there is a commonality (musical relation) in the performance form among these. For example, a bass drum (BD) and a snare drum (SD) have a tom tom high (TomH), a tom tom middle (Tom M), and a tom tom low (Tom).
L) is the conga high (Conga H), the conga low (Conga L) and timbre (Timb), the temple block high (TB H) and the temple block low (TB L) are the hi-hat. An open (HHO) and a hi-hat closed (HHC) make up one component each of Agougo's high (Agogo H) and Agougo's low (Agogo L). Therefore, tambourine (Tamb), claves (Clave), cowbell (Cowbell), hand craps (Claps), crash cymbals (Crash CY) and ride cymbals (Ride).
The CY) drum sound is a component that is treated as a single component.

However, tambourine (Tamb) and claves (Clave), cowbell (Cowbell) and hand craps (Claps), crash cymbal (Crash CY) and ride cymbal (Ride).
It goes without saying that each of CY) may be treated as one component. Also, other combinations may be used.

FIG. 2 is a diagram showing functional blocks when the electronic musical instrument 1F and the personal computer 20 of FIG. 1 operate as an accompaniment pattern creating device. The accompaniment pattern creating apparatus of FIG. 2 mainly operates on the current pattern memory 1. The personal computer 20 is adapted to perform automatic accompaniment processing while reading out the current pattern from the current pattern memory 1.

The current pattern memory 1, the assign memory 2, the undo buffer 3, the save memory 4 and the pattern table 63 correspond to predetermined areas of the RAM 23 shown in FIG. 3, respectively. The database means 5 corresponds to the hard disk device 24 of FIG. Database means 5
Stores a large number of rhythm pattern data as shown in FIG. The pattern selector 61 includes the designated keys of the note number A3, A # 3, B3, ..., E5 of the keyboard 1A of FIG. The designated keys B and C correspond to each other.

Therefore, in this accompaniment pattern creating apparatus, when the component in the database means 5 is appropriately selected by the pattern selector 61, the rhythm pattern data corresponding thereto is read from the database means 5 and supplied to the current pattern memory 1. . In this embodiment, the pattern selector 61 selects components.
That is, the component corresponding to the note number generated by the operation of the keyboard 1A and designated by the operation of the keyboard 1A is designated. At this time, since there are a plurality of rhythm patterns in each component, which rhythm pattern data of the designated component is read is determined by the velocity data at the time of operating the keyboard 1A.

That is, the start address of each rhythm pattern data forming each bank A, B, C in the database means 5 is stored in the pattern table 63 as an address in the order corresponding to the complexity of the rhythm pattern as shown in FIG. It is recorded. Therefore, by associating the velocity data when the pattern selector 61 is operated with the address of the pattern table 63, the pattern table 63
Is supplied to the pattern selector 61 from the start address of the rhythm pattern data having different complexity depending on the size of the velocity data. Pattern selector 61
Reads the rhythm pattern data stored in the address designated by the head address of the database means 5 and supplies it to the current pattern memory 1.
The rhythm pattern data read from the database means 5 is stored in the current pattern memory 1 as a current pattern. The contents of the stored current pattern are variously modified by the edit means 7 and the transformer 9.

The editing means 7 is a replace input key for the note number F # 2 of the keyboard 1A of FIG. 1, an insert input key for the note number G # 2, a quantizing process designation key for the note number A # 2, and a note number C # 3. Of the delete drum instruction key, the note number D # 3 delete component instruction key, and the note number F # 3 accent input key.

Here, the replace input means to erase the original note event data of the current pattern and store only new note event data. The insert input means that new note event data is added to the original note event data of the current pattern and stored. Quantize means to just fit the timing of note event occurrence to the reference timing. Accent is a drum sound in the current pattern, and means to re-accent the drum sound corresponding to the operated keyboard. The delete drum is a drum sound in the current pattern, and means deleting only the drum sound corresponding to the operated keyboard. The delete component is the drum sound in the current pattern,
This refers to deleting all the drum sounds of the component corresponding to the operated keyboard.

The adjective designating means 8 corresponds to the transformer designation keys of the note numbers D2, E2, F2, G2 and A2 of the keyboard 1A of FIG. Transformer 9
Corresponds to the transformer program stored in the ROM 22 of FIG. The contents of the current pattern are transformed according to the adjective instructed by the adjective instructing means 8 corresponding to this transformer designation key. This transformer 9 creates a pattern according to the desired image only by giving a sensory adjective instruction.

The undo means 10 corresponds to the undo key of the note number B2 on the keyboard 1A of FIG. Since the pattern transformed by the transformer 9 is stored in the undo buffer 3, if the desired pattern cannot be obtained as a result of the transformation, the original pattern can be recalled. That is, since the deformed pattern is stored in the undo buffer 3 in the modification processing order, the original pattern can be recalled by sequentially reading back the contents of the undo buffer 3. In this way, the current pattern created by adding or transforming a new pattern is stored in the assign memory 2
The pattern stored in the assign memory 2 can be read at any time by operating a key in the pattern assign area of the keyboard 1A.

The pattern registration means 62 corresponds to the pattern registration operator on the panel switch 2B of FIG. The pattern registration means 62 newly registers the current pattern in the current pattern memory 1, that is, the one that has been variously changed by the edit means 7 and the transformer 9 as new rhythm pattern data in the database means 5. At this time, the pattern registration means 62 obtains the complexity of the rhythm pattern data newly registered in the database means 5, rearranges the order in the pattern table 63 according to the complexity, and creates a new pattern table 63. .

For example, the complexity "20" as shown in FIG.
The rearrangement of the pattern tables will be described on the assumption that the rhythm pattern of Tom Tom Tom is newly registered in the pattern table for disco music of bank B of the database means 5. First, the pattern registration means 62
Database means 5 for the rhythm pattern of Tom Tam Tom
Register at the address "B-n1". Then, the pattern registration means 62 obtains the complexity of the rhythm pattern of the tom Tom Tom. Since the complexity of the rhythm pattern of the tom Tom Tom is "20", the pattern registering means 62 causes the pattern registering means 62 to start addresses "C-1, B-3, C" after the address "3" of the disco music pattern table as shown in FIG. -2
Each of C-3, ..., Bn ”is moved backward by one address, and the start address“ Bn1 ”of the rhythm pattern of the tom Tom Tom is newly recorded at the position of the address“ 3 ”.

Next, FIG. 1 executed by the CPU 11
An example of the processing of the electronic musical instrument 1F will be described with reference to the flowchart of FIG. FIG. 7A is C of the electronic musical instrument 1F of FIG.
It is a figure which shows an example of the main routine which PU11 processes. First, when the power is turned on, the CPU 11 causes the ROM 1
The process according to the control program stored in 2 is started. In the "initialization process", various registers and flags in the RAM 13 are initialized. Then the CPU
Reference numeral 11 repeatedly executes "key processing", "MIDI reception processing" and "other processing" in response to the occurrence of an event.

FIG. 7B is a diagram showing details of the "key processing" in FIG. 7 (A). In the "key processing", it is determined whether the operation state of the keyboard 1A is the key-on state or the key-off state, and a MIDI note-on message or a MIDI note-off message is sent to the personal computer 20 via the MIDI interfaces 1D and 2C according to the decision result. Output. Therefore, in this embodiment, even when the keyboard 1A is operated, the processing of the electronic musical instrument itself, that is, the sound source circuit 17 is not driven. Therefore, the tone generator circuit 17 does not perform sound generation processing at the time of key processing.

FIG. 7C is a diagram showing the details of the "MIDI receiving process" of FIG. 7A. The "MIDI reception process" is executed each time a MIDI message is input from the personal computer 20 via the MIDI interfaces 2C and 1D. In the "MIDI reception process", it is determined whether or not the MIDI message is a note-on message, and in the case of note-on (YES), the note-on signal, note number and velocity data are supplied to the tone generator circuit 17,
The tone generator circuit 17 is caused to generate a musical sound. Meanwhile, MIDI
If the message is other than note-on (NO), "message handling" according to the received MIDI message
After that, the process returns to the main routine of FIG. In "other processing", processing based on the operation of other operators on the panel switch 1B and various other processing are performed.

Next, FIG. 1 executed by the CPU 21
An example of the processing of the personal computer 20 will be described with reference to the flowcharts of FIGS. FIG. 8A is a diagram showing an example of a main routine processed by the CPU 21 of the personal computer 20 shown in FIG. First, when the power is turned on, the CPU 21 starts processing according to the control program stored in the ROM 22. In the "initialization process", RAM2
Initialize various registers and flags in 3. After that, the CPU 21 performs “MIDI reception processing” and “display processing”.
And "other processing" are repeatedly executed.

FIG. 8B is a diagram showing the details of the "MIDI receiving process" of FIG. 8A. "MIDI reception processing"
Is executed each time a MIDI message is input from the electronic musical instrument 1F via the MIDI interfaces 1D and 2C. In the "MIDI reception process", it is determined whether or not the MIDI message is a note-on message, and in the case of note-on (YES), the process corresponding to the note number of the key-on (the process of FIGS. 9 to 12) is executed, In the case of note-off (NO), the process (the process of FIG. 13) corresponding to the key-off note number is executed.

In the "display process", a process for displaying on the display 29 which bank of the database means 5 is being processed, the type of drum sound being played, and which part of the current pattern is being played. I do. Specifically, the screens shown in FIG. 5 and FIG. 21 are displayed. In the "other processing", processing based on the operation of other operators on the panel switch 2B and various other processing are performed. Here, the "pattern registration process" of FIG. 17 according to the operation of the pattern registration operator on the panel switch 2B is performed. The details of this “pattern registration process” will be described later.

9 to 12 are executed when the received MIDI message is a note-on message.
It is a figure which shows the process corresponding to the note number of the note-on message of (B). In FIG. 9A, note numbers E0 to E0 are generated by operating the keys in the pattern assign area corresponding to the note numbers E0 to B1 on the keyboard 1A.
It is a figure which shows the pattern assign area key process performed when the MIDI message containing B1 is received from the electronic musical instrument 1F. In this pattern assign area key processing, it is first determined whether the assign flag ASSIGN is at high level "1", and processing is performed according to the determination result.

That is, the assign flag ASSIGN
Is set to a high level “1” by the assign key processing of FIG. 9B when the assign key (key of note number C2) of the keyboard 1A is key-on operated, and conversely when it is key-off operated. 13A is reset to the low level "0". Therefore, the assignment flag ASSIGN is at the high level "1" (YES).
If so, it means that the key in the pattern assign area and the assign key are pressed at the same time. In this case, therefore, the current pattern in the current pattern memory 1 is assigned to the note number. Copy to the assigned memory area of the memory 2 and return.

On the other hand, when the assign flag ASSIGN is determined to be low level "0" (NO), it means that only the key of the pattern assign area is operated, and in this case, the note number is The rhythm pattern stored in the corresponding assign memory area of the assign memory 2 is copied to the current pattern memory 1 and the process returns.

That is, when the key of the pattern assign area is operated while pressing the assign key, the rhythm pattern data stored in the current pattern memory 1 at that time is registered in the key of the pattern assign area. When only one of the keys is operated independently, the rhythm pattern registered in advance for that key is recalled to the current pattern memory 1.

~ Transformers compatible with A2 (excluding #) 1 ~
FIG. 9 is a diagram showing a transformer key process performed when the key 5 is operated and a MIDI message including note numbers D2 to A2 (excluding #) is received from the electronic musical instrument 1F. The fact that the MIDI message including the note numbers D2 to A2 (excluding #) is received from the electronic musical instrument 1F means that the type of the adjective of the transformer is designated. Therefore, in this transformer key processing, first, all flags are cleared to low level "0", and the type of the adjective of the transformer is determined according to the note number and velocity data in the MIDI message. When the type of transformer is determined, the transformer flag TRANS is set to a high level "1" and the process returns.

In this embodiment, two adjectives are assigned to each of the transformers 1 to 5, and one of them is selected according to the size of velocity data.

FIG. 17 shows the "pattern registration process" in the "other processes" of FIG. 8 performed by the CPU 21 of the personal computer 20.
It is a figure which shows the detail of. This "pattern registration process" is
When registering new rhythm pattern data in the current pattern memory 1 in the database means 5, the complexity of the rhythm pattern data is obtained, and it is determined at which level of the pattern table 63 the complexity is located. This is a process of registering at the level position and rewriting the pattern table 63. This process is sequentially executed in the following steps.

Step 71: The complexity of the rhythm pattern to be newly registered is obtained, and the complexity is stored in the newly registered complexity register COMP (N). Step 72: The complexity of the rhythm pattern of the address register AD = 1 is read from the pattern table 63 of FIG. 2, and the complexity is registered as the registered complexity register COMP (D).
To be stored. The address register AD stores the address on the pattern table of FIG.

Step 73: New registration complexity register C
The complexity of OMP (N) is the registered complexity register COMP.
It is determined whether the complexity is smaller than (D). If it is smaller (YES), the process proceeds to step 76, and if it is the same or larger (NO), the process proceeds to step 74. Step 74: The address register AD is incremented by 1. Step 75: The complexity of the rhythm pattern recorded at the address of the address register AD is read from the pattern table 63, the complexity is stored in the registered complexity register COMP (D), and the process returns to step 73. That is, in steps 73 to 75, the complexity of the newly registered rhythm pattern is the current pattern table 63.
Detect which address corresponds to the above.

Step 76: Since it was determined in the previous step 73 that the complexity of the newly registered complexity register COMP (N) is lower than the complexity of the already registered complexity register COMP (D), the address register here is selected. The head address of the rhythm pattern after the address of AD is shifted backward by one address and recorded. Step 77: Register the start address of the newly registered rhythm pattern and its complexity at the address position of the address register AD.

18 to 20 are diagrams showing an example of the arithmetic processing for changing the contents of the current pattern by the transformer processing.

If the rhythm pattern corresponds to 220 to 260 340 to 380 460 to 20), it becomes a change target and is replaced with replacement data.

The replace data (0 160 320) of the replace template indicates the rhythm pattern to be replaced. The velocity selection data indicates which note of the search data is used as the velocity of the replace data. That is, "0" of the velocity selection data indicates the velocity of the first data (8th note) of the search data, and "1" indicates the second data of the search data (the first 16th note). ), And "2" indicates the velocity of the third data (second 16th note) of the search data. Each order of velocity selection data corresponds to the order of replace data.

In the third rhythm pattern, the drum sound of the third data (sixteenth note) of the search data is replaced by the first, second and third data (3
The first, second, and third notes of the tuplet) are replaced by drum sounds. In the fourth rhythm pattern, the drum sound of the first data (eighth note) of the search data is changed to the drum sound of the first data (first note of triplet note) of the replace data. The drum sound of the second data (16th note) of the data is the second of the replacement data.
The drum sound of the 3rd data (16th note) of the search data and the drum sound of the 3rd data (16th note) of the search data are added to the drum sound of the 3rd data (2nd note of the triplet). 3rd note) drum sound, respectively. This state is shown by an arrow in the portion of each of the rhythm patterns in FIGS. 20C and 20D in which triplets are replaced.

FIG. 21 is a diagram showing a display example of the display screen of the display 29 of FIG. The bank display unit 29A is
This shows which bank of the hard disk device 24 the current bank is. The figure shows that the current bank is bank A. This bank display section 29A
Underneath, there is a part showing the current state of the current pattern. This part is composed of a drum sound name display section 29B, a current sound generation display section 29C, a current pattern display section 29D, and a current position display section 29E. The drum sound name display portion 29B displays the drum sound name corresponding to the keyboard 1A. The current sound display unit 29C is composed of a circular lighting unit provided on the right side of each drum sound, and only the lighting unit corresponding to the currently sounding drum sound is lit. The current pattern display portion 29D is configured to display a rhythm pattern for one measure by a square lighting portion. In the figure, the closed rhythm patterns of the bass drum, snare drum, and hi-hat are displayed. The current position display portion 29E indicates the position currently being sounded in one bar.

By making such a display, it is possible to recognize at a glance the contents of the drum sound to be sounded and the current pattern. Further, even if this current pattern is deformed, the contents of the deformation can be easily grasped. In this case, the pattern before the deformation and the pattern after the deformation may be displayed at the same time. Furthermore, FIG.
The degree of complexity such as may be displayed at the same time.

In the above embodiments, the rhythm accompaniment is described as an example, but the present invention is not limited to this, and the present invention may be applied to accompaniments such as bass and chord backing. For example, a large number of base patterns and a large number of backing patterns may be stored in the database, and one of the patterns may be selected for each part by the operation of the operator. That is, the base part, the packing part 1,
2, 3, ... (Each backing part has a different timbre)
Each operator of the above is provided, and when the operator of the base part is operated, one of the base patterns is selected from the database, and when the operator of the packing part 1 is operated, one of the backing patterns is selected from the database. Good.

Further, in the above-mentioned embodiment, the case where the flag correspondence process 2 (undo process, fill-in process, variation process, transformer process) is executed at the time when the performance up to the bar line is finished has been described. The process may be executed immediately when the key corresponding to is operated.

In the accent processing in step 52 of FIG. 15, the velocity corresponding to the note number being note-on is directly replaced with the note-on velocity,
Although it is used as an accent, a plurality of accent templates (for example, a pattern indicating how much velocity should be replaced at each timing) such as the search template and the replace template described above are easily prepared.
These may be selected according to the velocities corresponding to the note-on note numbers, and the velocities of the selected accent template may be replaced with the note-on velocities.

In the above-mentioned embodiment, the keyboard of the keyboard instrument is used as the keys for assigning various functions. However, various functions are designated by displaying switches on the display of the personal computer and designating the switches. Good. In addition to the keyboard, a drum pad or the like may be used, or a simple switch may be used. Further, in the above-described embodiment, the case where all the functions are designated by the keyboard has been described, but the lock function may be assigned to the foot switch, or the various functions may be designated in combination with other operating elements. Good.

Further, in the embodiment, the electronic musical instrument and the personal computer are connected by the MIDI line to constitute the automatic accompaniment apparatus.
It may be applied to a single electronic musical instrument. In the example above,
When specifying a transformer adjective, two types of adjectives were assigned to one key and switched according to the velocity value, but the degree of deformation by the adjective is changed step by step according to the velocity value. You may switch to. Also, one adjective may be assigned to one key.

In the above-described embodiment, four measures are assigned as the adjective sequence data, and the sequence of adjectives for which the performance of these four measures has ended is also ended. The sequence data for nodes may be repeatedly executed. Further, it goes without saying that the sequence data is not limited to four measures and may be any number of measures. Furthermore, the designation of adjectives need not be the timing of bar lines.

Further, when the rhythm pattern is transformed by the transformer, different transformation processing may be performed depending on the contents of the current rhythm pattern. For example, add a drum sound by a transformer,
Alternatively, in the case of transformation such as replacement, it is determined what kind of pattern the current rhythm pattern is, and a drum sound to be added or a pattern to be replaced depending on whether it is a 16-beat rhythm pattern or an 8-beat rhythm pattern. May be different.

Another embodiment of the present invention will be described below.
In another embodiment, in addition to the address area, the head address area, and the complexity area, the pattern table includes a valid / invalid flag area for storing a valid flag or an invalid flag indicating whether or not the rhythm pattern can be selectively set. The case of having will be described.

FIG. 22 is a diagram showing the contents of a pattern table for address conversion stored in the pattern table area. In the figure, a pattern table for rock music and a pattern table for disco music are shown. The pattern table includes an address area, a head address area, a complexity area, and a valid / invalid flag area. The address of the pattern table is stored in the address area, the head address of each of the banks A, B, C of the rhythm pattern is stored in the head address area, and the degree of complexity of the rhythm pattern is stored in the complexity area. Is stored, and a valid flag or invalid flag indicating whether or not the rhythm pattern can be selected is stored in the valid / invalid flag area.

For example, the rock music pattern table has head addresses A-1, A-2, A for specifying a plurality of rhythm patterns stored in banks A and C.
-3, C-1, A-4, C-2, ..., An in the order 1, 2, 3, according to the degree of complexity (magnitude of complexity) of the rhythm pattern. ..., n is stored as an address. On the other hand, the disco music pattern table has head addresses B-1 and B- for specifying a plurality of rhythm patterns stored in the banks B and C.
2, C-1, B-3, C-2, C-3, ..., Bn
, N are stored as addresses in the order of 1, 2, 3, ..., N according to the degree of complexity (magnitude of complexity) of the rhythm pattern.

Here, A and B in the head address area
Alternatively, C indicates the type of bank in which the rhythm pattern is stored. That is, the start addresses A-1, A-
2, A-3, A-4, A-n indicate the address of the bank A, the start addresses B-1, B-2, B-3, B-n indicate the address of the bank B, and the start address C-. 1, C-
2, C-3 indicate the address of bank C.

The complexity in the complexity area is the same as that in FIG. The rhythm patterns that can be selected from among the rhythm patterns in the rock music pattern table, that is, the ones for which the valid flag is set, have the address "1",
“2”, “4”, “6”, ..., “N”. Of the rhythm patterns in the disco music pattern table, selectable ones, that is, those having a valid flag, are addresses "1", "2", "4", "6", ...
..., "n". Therefore, even if the pattern selector 61 selects a pattern other than the one for which the valid flag is set, the selection is invalid, and another pattern for which the valid flag is set is selected.

As described above, by setting some of the accompaniment patterns in the database to be unselectable, there is no inconvenience that the accompaniment pattern is not desired to be selected during real-time automatic accompaniment. , It becomes possible to perform automatic accompaniment as desired by the user. In this case, it may be possible to set which accompaniment pattern can be selected (valid or invalid) for each component. Also, which pattern is not selectable may be preset.
The user may set it arbitrarily.

In the above-mentioned embodiment, as the operators for designating the components, the designation keys of the drum pattern area of the note numbers A3, A # 3, B3, ..., E5 of the keyboard 1A of FIG. 2 correspond. However, the case where the note number generated in response to the key operation of this designation key is output as the component designation signal has been described, but a dedicated component designation switch corresponding to each component is provided on the panel switch 1B or 2B, and A desired component may be designated by operating.

In the above-described embodiment, the pattern selector 61 for selecting a pattern is used as the keyboard 1 of FIG.
Note keys of A, A # 3, B3, ..., E5 correspond to designated keys in the drum pattern area, and velocity data generated in response to key operation of the designated keys is output as a pattern selection signal. As described above, the panel switch 1B or 2B is used as a pattern selector, which is an operator capable of outputting continuous values such as a slide operator, a rotary operator such as a wheel, or a multidimensional operator such as a joystick. Alternatively, the pattern selection signal may be provided on the upper side and operated to output the pattern selection signal.

At this time, the pattern selection signal from the pattern selector is treated as an absolute value signal or processed as a relative value signal. That is, when the pattern selection signal is processed as a relative value signal, it becomes easy to understand how much the pattern is different from the previously selected pattern (for example, how different the pattern is in complexity). Also,
It is possible to appropriately select whether to use an absolute value or a relative value, and to select in an easy-to-select method according to a user's preference.

In FIG. 23, the component designating operator is constituted by each key of the drum pattern area of the note numbers A3 to E5 of the keyboard 1A, and the pattern selecting operator is a slide type provided on the panel switch 1B or 2B. If it is composed of various operators that can output continuous values, such as rotary operators such as operators and wheels, and multidimensional operators such as joysticks, etc., component designated operators and pattern selection It is a figure which shows the process performed by operating an operator. FIG. 23 (A)
23B is a pattern selection operator process corresponding to the operation of the pattern selection operator, and FIG. 23B shows M including note numbers A3 to E5 corresponding to the operation of the component designating operator.
It is a figure which shows the drum key process performed when an IDI message is received from the electronic musical instrument 1F. When the pattern selection operator is provided on the panel switch 1B of the electronic musical instrument 1F, the MIDI message includes the note numbers A3 to E5 and the pattern selection signal corresponding to the operation of the operator 6B. .

In the pattern selection operator processing of FIG. 23A, it is first judged whether or not there is a change in the output value of the operator,
When there is a change (YES), the output value is taken in, and when there is no change (NO), the process returns. This process is executed every predetermined time. The drum key processing of FIG. 23B is almost the same as that of FIG. 11D. First, it is determined whether any of the flags other than the lock flag LOCK is at the high level “1”, and the high level “1” (YES). 12) corresponding to the flag set to the high level “1”, the flag corresponding process 1 of FIG. 12 is executed and the process returns.

On the other hand, when it is determined that none of the flags other than the lock flag LOCK is high level "1" (NO), the sound of the component corresponding to the depressed key (note number) (for some, (Drum sound) is deleted from the current pattern and temporarily saved in the save memory 4. Then, with the pressed key (note number),
The rhythm pattern of the component (drum) corresponding to the output value from the pattern selection operator and the genre is selected by referring to the pattern table 63, and the rhythm pattern of the selected component is read from the database means 5 and added to the current pattern. . Then, the complexity of the selected rhythm pattern is displayed on the display 2 as shown in FIG.
Display on 9. When the pattern selection operator is not operated, the values up to the last time are retained, so that the component can be specified simply by pressing the key corresponding to the note number A3 to E5, and the delicate selection of the accompaniment pattern. The setting can be performed by subtly changing the continuous output value from the pattern selection operator and then operating the keys of note numbers A3 to E5.

FIG. 24 shows a case where both the component designating operator and the pattern selecting operator are constituted by the keys of the note number A3 to E5 of the keyboard 1A in the drum pattern area, as in FIG. 11D. , Receives a MIDI message including note numbers A3 to E5 and velocity data generated by the key operation from the electronic musical instrument 1F, recognizes the received velocity data as an absolute value or a relative value, and outputs a pattern selection signal accordingly. It is a figure which shows the drum key process performed when performing.

The drum key processing of FIG. 24 is the same as that of FIG.
First, it is determined whether any of the flags other than the lock flag LOCK is at the high level “1”,
When it is determined that the flag is the high level "1" (YES), the flag corresponding process 1 of FIG. 12 corresponding to the flag set to the high level "1" is executed and the process returns.
On the other hand, when it is determined that none of the flags other than the lock flag LOCK is high level “1” (NO), the sound of the component corresponding to the pressed key (note number) (a drum sound for a part) Is deleted from the current pattern and temporarily saved in the save memory 4.

Then, it is determined whether the velocity recognition mode is the relative value mode. If the relative value mode is determined, the pressed key (note number),
The rhythm pattern of the component (drum) corresponding to the relative value of the velocity data and the genre is selected by referring to the pattern table 63, and the rhythm pattern of the selected component is read from the database means 5 and added to the current pattern. The relative value is, for example, “current selection data = previous selection data + relative value (current velocity−64)” (that is, current velocity is 64).
If it is larger than 64, a slightly more complicated pattern than the previously selected pattern is selected, and if it is smaller than 64, a slightly simpler pattern is selected).

On the other hand, when the absolute value mode is determined, the pattern table 63 is referred to for the rhythm pattern of the depressed key (note number), the absolute value of velocity data, and the component (drum) corresponding to the genre. Then, the rhythm pattern of the selected component is read from the database means 5 and added to the current pattern. Then, the complexity of the selected rhythm pattern is displayed on the display 29 as shown in FIG.

In the above drum key processing, the pattern selection signal corresponding to the absolute value of the velocity data may be output first, and then the pattern selection signal corresponding to the relative value may be output. Alternatively, a predetermined absolute value may be automatically output at first and then a pattern selection signal corresponding to the relative value may be output. Further, the user may appropriately select whether to select the pattern by the absolute value or the relative value.

The case where the pattern selection operator is velocity data corresponding to the keyboard operation has been described as an example, but the present invention is not limited to this, and the pattern selection operator is provided on the panel switch 1B or 2B. It is needless to say that the same can be applied even if it is composed of various types of operators capable of outputting continuous values such as slide type operators, rotary operators such as wheels, and multidimensional operators such as joysticks. Absent.

FIG. 25 is a diagram showing the drum key processing when the invalid flag exists in the valid / invalid flag area of the pattern table as shown in FIG. 22 and the pattern unselectable state occurs. In this process, the component designating operator is constituted by each key of the drum pattern area of the note numbers A3 to E5 of the keyboard 1A, and the pattern selecting operator is a slide type operator or a wheel provided on the panel switch 2B. A case will be described in which the rotary type operator, the multi-dimensional operator such as a joystick, or the like is configured with an operator that can output continuous values.

In this drum key processing, first, one of the flags other than the lock flag LOCK is at the high level "1".
If it is determined that the flag is the high level "1" (YES), the flag corresponding process 1 of FIG. 12 corresponding to the flag set to the high level "1" is executed and the process returns. . On the other hand, when it is determined that none of the flags other than the lock flag LOCK is high level “1” (NO), the sound of the component corresponding to the pressed key (note number) (a drum sound for a part)
Is deleted from the current pattern and temporarily saved in the save memory 4.

Then, the pressed key (note number)
And the rhythm pattern of the component (drum) corresponding to the output value from the pattern selection operator and the genre is selected with reference to the pattern table 63. It is determined whether the selected pattern is in the valid state or the invalid state. If the valid state (YES), the process proceeds to the next step, and if it is the invalid state (NO), the next valid rhythm pattern is selected. Select complex patterns in sequence. When a valid rhythm pattern is selected, the rhythm pattern of that component is read from the database means 5 and added to the current pattern. Then, the complexity of the selected rhythm pattern is displayed on the display 29 as shown in FIG. This eliminates the inconvenience of playing with an accompaniment pattern that is not desired to be selected during real-time automatic accompaniment, and allows automatic accompaniment as desired by the user.

In this embodiment, if the pattern corresponding to the output value from the pattern selection operator cannot be selected, the next complicated pattern is selected.
You may make it select the thing whose complexity is one lower (small complexity). Further, if the most complicated (or simple) pattern is reached as a result of selecting the next complicated (or simple) pattern, the pattern may be searched in the opposite direction. In addition, in this embodiment, the pattern selection operator has continuous values such as a slide operator provided on the panel switch 1B or 2B, a rotary operator such as a wheel, and a multidimensional operator such as a joystick. Although the description has been made by taking as an example the case where the control element is capable of outputting, the same can be applied to the case where the velocity data generated according to the key operation is used as the pattern selection signal. In this case, the velocity resolution (value obtained by dividing the velocity value range into the number of patterns) may be changed. That is, when the velocity value is 128 steps from 0 to 127 and the number of patterns is 50, the resolution is 2.56 = 128/50 (a different pattern is selected every time the velocity value increases by 2.56). )
However, when the number of selectable patterns becomes 40 by making some patterns unselectable, the resolution becomes 3.2 = 128/40.

In the drum key processing of FIGS. 23 to 25, the case where the rhythm pattern of the selected component is added to the current pattern as it is has been described. However, only a part (specified range) of the rhythm pattern is added, or A case will be described in which only an arbitrary one of the plurality of drum sounds constituting the component is selectively added.

In FIG. 26, it is possible to add only a part (specified range) of the rhythm pattern, or selectively add only an arbitrary one of the plurality of drum sounds constituting the component. It is a figure which shows another example of a drum key process. FIG. 27 shows how a rhythm pattern is added by the drum key processing of FIG.
It is a figure which shows that notionally. First, before executing the drum key processing of FIG. 26, if a specific range of the rhythm pattern is specified by a range specifying switch (not shown) on the panel switch 2B, the "specified range mode" is set, and the drum is specified. When an arbitrary drum sound is designated by a switch (not shown), the "designated drum mode" is set. If nothing is specified, the "normal mode" is set.

For example, when the length of the basic accompaniment pattern stored in the database means 5 is one bar as shown in FIG. 27A, the range designation switch is the first one of the one bar. It is possible to specify only a certain range of one bar, such as only the beat, only the first half of one bar, or only the second half. Therefore, after a certain range of one bar is designated by the range designation switch, the "designated range mode" is set. In FIG. 27A, only the first half portion of the one-bar pattern stored in the database means 5 is designated by the range designation switch, and the designated range is read into the current pattern memory 1 as the current pattern CP1. The case is shown.

When the basic accompaniment pattern stored in the database means 5 is composed of a plurality of drum sounds as shown in FIG. 27 (B), the drum designating switch indicates the drum sounds. Only specific drum sounds can be specified. For example, if you like the bass drum BD in the current pattern but do not like the snare drum SD, you can replace it by designating only the snare drum SD pattern with the drum designating switch. You can Therefore, after the specific drum sound is designated by the drum sound designating switch, the "designated drum mode" is set.

In FIG. 27B, a specific drum sound (upper snare drum SD) of a one-bar pattern in which a plurality of drum sounds (upper snare drum SD, lower drum bass BD) are mixed in the database means 5 is shown in FIG. Only the designated drum sound is designated by the drum designation switch, and only the designated drum sound is read into the current pattern memory 1 as the current pattern C2. Note that FIG. 27B
As shown in FIG. 5, all the drum sounds of a one-bar pattern in which a plurality of drum sounds (the snare drum SD in the upper stage and the bass drum BD in the lower stage) are mixed in the database means 5 are designated by the drum designating switch, and a specific drum among them is designated. Only for the sound (upper snare drum SD), when the specific range (first half of one bar) is designated by the range designating switch, only the designated range of the designated drum sound is the current pattern C3. It may be read into the memory 1.

In this way, the mode (specified range mode,
When the keys in the drum pattern areas of the note numbers A3 to E5 of the keyboard 1A are operated after the designated drum mode and the normal mode) are confirmed, the drum key processing of FIG. 26 is executed. In the drum key processing of FIG. 26, first, it is determined whether or not any flag other than the lock flag LOCK is at the high level "1", and the high level "1" (YES).
If it is determined that the flag is set, the flag correspondence processing 1 of FIG. 12 corresponding to the flag set to the high level “1”
And then return. On the other hand, the lock flag LOCK
None of the flags other than is high level "1" (N
If it is determined to be O), the component sound (a part of the drum sound) corresponding to the pressed key (note number) is deleted from the current pattern and saved in the save memory 4
Temporarily evacuate to.

Then, the pressed key (note number)
And the rhythm pattern of the component (drum) corresponding to the output value from the pattern selection operator and the genre is selected with reference to the pattern table 63. Next, it is determined what the current mode is and the processing corresponding to the current mode is performed.
When the current mode is the "specified range mode", the selected rhythm pattern is read from the database means 5 and only the specified range of the patterns is added to the current pattern.

When the current mode is the "designated drum mode", the selected rhythm pattern is read from the database means 5 and only the designated drum sound pattern is added to the current pattern. When the current mode is the “normal mode”, the above-mentioned FIGS.
The selected rhythm pattern is read from the database means 5 and all patterns are added to the current pattern in the same manner as in the above case. Then, the complexity of the selected rhythm pattern is displayed on the display 29 as shown in FIG.

As a result, the degree of freedom in forming the accompaniment pattern is improved, and only the favorite portion can be newly added. The selectable range may be arbitrarily set by the user, or a plurality of types may be preset. Further, when the accompaniment pattern is composed of a plurality of measures, one or a plurality of measures may be arbitrarily designated. When the component is composed of three or more drum sounds, two or more drum sounds may be designated as appropriate.

A fine adjustment operator capable of outputting a continuous value such as a slide operator, a rotary operator such as a wheel, or a multidimensional operator such as a joystick is provided for each component by a panel switch 1B or 2B. Installed on top,
A case where a pattern selection signal is output by operating this will be described. When this fine adjustment operator is operated, it is possible to continuously output a value according to the operation amount, so that it is possible to perform delicate selection setting of an accompaniment pattern as compared with selection using velocity data. There is an advantage that you can. When selecting an accompaniment pattern using velocity data, it is difficult to continuously change the value of velocity data, but there is an advantage that rough selection can be easily performed.

FIG. 28 shows "fine adjustment operator processing" in "other processing" of FIG. 8 performed by the CPU 21 of the personal computer 20.
It is a figure which shows the detail of. This process is executed when the fine adjustment operator provided for each component is operated. The fine adjustment operator is composed of a slide type operator, a rotary operator such as a wheel, and a multidimensional operator such as a joystick, and outputs continuous values. It is determined whether the output value of the manipulator has changed, and if it is determined that the output value has not changed (NO), the process immediately returns.

On the other hand, when it is determined that the output value has changed (YES), the sound of the component (a drum sound for a part) corresponding to the operated (changed output value) fine adjustment operator is current. The pattern is deleted and temporarily saved in the save memory 4. Then, the fine adjustment operator operated and the rhythm pattern of the component (drum) corresponding to the operation amount and genre are displayed in the pattern table 63.
The rhythm pattern of the selected component is read from the database means 5 and added to the current pattern. Then, the complexity of the selected rhythm pattern is displayed on the display 29 as shown in FIG. As a result, the components can be specified by finely selecting and setting the accompaniment pattern simply by operating the corresponding fine adjustment operator.

A case will be described in which a search condition designating operator for designating a desired search condition for pattern selection is provided as a pattern selector on the panel switch 1B or 2B. As a search condition by the search condition designating operator, "a pattern having an event at the second and fourth beats", "a pattern in which the total number of events is n or more", and "a timing at which an event of an arbitrary drum sound exists" , A pattern in which no other arbitrary drum sound event exists ”is designated by AND and OR, and an accompaniment pattern that matches the designated condition is selected. By doing so, only the pattern intended by the user is selected, so that the desired accompaniment pattern can be obtained earlier. These search conditions may be preset or may be arbitrarily set by the user. Further, the combination of conditions may be stored in advance.

When selecting a pattern of a certain component, a condition may be set in relation to another component. For example, when selecting the pattern of hi-hat HH, BD + selected at that time
If the SD pattern is # 1, select from the hi-hat HH patterns with a total event count of n or more, or when selecting the tom tom Tom pattern, BD
If the + SD pattern is # 1, the pattern can be selected based on a condition such as “select from the tom tom Tom patterns having events whose event timing does not overlap with BD”. If there is no pattern that matches the condition, a pattern that does not match the condition may be appropriately selected.

FIG. 29 shows the "condition designation search process" in the "other processes" of FIG. 8 performed by the CPU 21 of the personal computer 20.
It is a figure which shows the detail of. This processing is executed when the search condition designating operator is operated. In this process, first,
Search condition specification operator The search condition specified by the operation of the operator is imported. For example, "a pattern having an event at the 2nd and 4th beats", "a pattern in which the total number of events is n or more", "an event of an arbitrary drum sound at the timing when an event of an arbitrary drum sound exists" The conditions such as "there is no pattern" are captured. The rhythm pattern corresponding to the address “1” of the pattern table 63 is read from the database means 5. For example, in the case of the rock music rhythm pattern table of FIG. 22, the start address A-1
The rhythm pattern of is read out.

It is determined whether or not the read rhythm pattern matches the search condition. If they match (YES), a valid flag is set in the valid / invalid flag area of the rhythm pattern at the current address in the pattern table 63. If they do not match (NO), an invalid flag is set in the valid / invalid flag area of the rhythm pattern of the current address in the pattern table 63. Then, it is determined whether or not the current rhythm pattern is the last pattern in the pattern table 63. If the last pattern (YES), the process immediately returns, and if it is not the last pattern (NO), the rhythm pattern corresponding to the next address. Is read from the database means 5, and the determination as to whether the read rhythm pattern matches the search condition is repeatedly executed until the last rhythm pattern in the pattern table is reached. As a result, the valid / invalid flag is set in the pattern table 63 according to the search condition, so that only the rhythm pattern in which the valid flag exists, that is, the rhythm pattern that matches the search condition is selected by the drum key processing of FIG. Become.

FIG. 30 is a diagram showing details of the "drum sound replacement process" in the "other processes" of FIG. 8 performed by the CPU 21 of the personal computer 20. The drum sound replacement process of FIG. 30 is a process of replacing an arbitrary drum sound of the accompaniment pattern stored in the current pattern memory 1 with another drum sound. For example, when the user likes the drum pattern but does not like the timbre, it is a process of replacing it with a desired timbre.

In this process, first, the head data (drum sound data) of the current pattern stored in the current pattern memory 1 is read. It is determined whether or not the note number of this head data is the drum sound to be replaced. If the note number is the drum sound to be replaced (YES), the note number is converted into the note number of the replaced drum sound. After this conversion is completed, or after it is determined that the note number is not the drum sound to be replaced (NO), it is determined whether all the data (patterns) stored in the current pattern memory 1 have been read out. To do. If the reading of all data is completed (YES), the process returns. If it is not completed (NO), the next data (pattern) in the current pattern memory 1 is read. Then, the same replacement process as described above depending on whether the replacement target is the note number is repeatedly executed until the reading of all data (patterns) is completed.

By replacing the note numbers in this way, the tone color of the drum sound can be replaced.
The replacement may be performed by rewriting the data indicating the tone color in the current pattern (usually the note number), or converting it when the pattern data is output. Also,
The data indicating the tone color may be converted when the pattern is read from the database means 5, or may be converted when the pattern is written in the current pattern. Further, the contents of the database means 5 may be directly rewritten.

FIG. 31 is a diagram showing another embodiment of the drum sound replacement process of FIG. 30 for replacing the tone color of the drum sound when the pattern data is read from the current pattern memory 1 and the note event is output. This process
Step 5 in the MIDI note event output process of FIG.
It is realized by newly adding 9 and 5A. In FIG. 31, the same components as those in FIG. 15 are designated by the same reference numerals, and the description thereof will be omitted.
The process of FIG. 31 is different from the process of FIG.
The point is that steps 59 and 5A are executed before the note event of 8 is output.

That is, in step 59, step 5
Note event accented in 2, step 5
It is determined whether or not the note number remaining as a result of the deletion in step 4 or the note number of the note event that has not undergone the processing of steps 52, 54 and 56 is the drum sound to be replaced. If the note number is the drum sound to be replaced (YES), the note number is converted to the note number of the replaced drum sound in step 5A. The note number is not the drum sound to be replaced (N
If O), go to step 58. Therefore, step 5
In step 8, the note event converted in step 5A or the note event not converted in step 5A is output to the electronic musical instrument 1F via the MIDI interfaces 2C and 1D.

A case will be described in which a selection pattern input operator for inputting a pattern desired by the user is provided on the panel switch 1B or 2B as a pattern selector. The pattern input operator may be replaced by the keyboard 1A shown in FIG. 2, or a dedicated operator may be provided. That is, the selection pattern input operator outputs a pattern that is imaged by the user and that is input by the real-time method or the step input method (the user wants to select a pattern having such a feeling). The accompaniment pattern creation device appropriately selects from the database means 5 a pattern that is considered to be the closest to the input pattern. This allows the user to quickly select the pattern to image.

FIG. 32 is a diagram showing details of the “similar pattern selection process” in the “other processes” of FIG. 8 performed by the CPU 21 of the personal computer 20. This process is executed when the selection pattern input operator is operated. The selection pattern input operator inputs a pattern imaged by the user (a user wants to select such a pattern) in real time or in a step input method. Therefore, in this similar pattern selection processing, the flag in the valid / invalid flag area of the pattern table 63 is rewritten so that a pattern similar to the input pattern can be easily selected from the database means 5.

In this process, first, the arbitrary pattern input by the selection pattern input operator is fetched. The rhythm pattern corresponding to the address “1” of the pattern table 63 is read from the database means 5. For example, in the case of the rock music rhythm pattern table of FIG. 22, the rhythm pattern of the head address A-1 is read, and in the case of the disco music pattern table of FIG. 22, the rhythm pattern of the head address B-1 is read. Read out.

It is determined whether the read rhythm pattern is similar to the input arbitrary pattern. If they are similar (YES), a valid flag is set in the valid / invalid flag area of the rhythm pattern at the current address in the pattern table 63. On the other hand, if they are not similar (NO), an invalid flag is set in the valid / invalid flag area of the rhythm pattern of the current address in the pattern table 63.

Then, it is determined whether or not the current rhythm pattern is the pattern of the last address in the pattern table 63. In the case of the last address pattern (YES), the process immediately returns. If it is not the last address pattern (NO), the rhythm pattern corresponding to the next address is read from the database means 5. Then, the determination as to whether the read rhythm pattern is similar to the arbitrary pattern is repeatedly performed until the rhythm pattern at the last address in the pattern table is reached.

As a result, the valid flag or invalid flag is set in the pattern table 63 in correspondence with a pattern close to an arbitrary pattern, so that the drum key processing shown in FIG. 25 approximates a rhythm pattern having an effective flag, that is, an arbitrary pattern. Only the rhythm pattern is selected, and the user can quickly select the pattern that he or she imagines. The degree of similarity indicating whether or not the pattern is close to the arbitrary pattern may be determined as follows. For example, the degree of similarity may be determined by using the number of sounds in the pattern being equal to or close to each other, the positions of existence of sounds in the pattern being equal to or close to each other, or by using them collectively. Further, the similarity may be determined based on a specific component or a pattern of drum sounds, or may be determined for all drum sounds.

A case will be described in which a sequential reproduction means for sequentially reading and reproducing the accompaniment patterns of the designated component among the plurality of accompaniment patterns stored in the database means 5 is provided. By sequentially reproducing the accompaniment patterns by the sequential reproducing means, it is possible to confirm all kinds of patterns stored in the database means 5. Therefore, when the accompaniment pattern desired by the user does not exist, a new pattern may be added or an existing pattern may be modified by editing or the like to create a desired pattern. If you find a pattern you like, you can select it. It is extremely important for the user to select a desired pattern in advance by grasping the arrangement of accompaniment patterns stored in the database means 5 in advance.

FIG. 33 is a diagram showing details of the “pattern sequential reproduction process” in the “other processes” of FIG. 8 performed by the CPU 21 of the personal computer 20. This processing is executed when the sequential reproduction means 64 of FIG. 1 is operated. The sequential reproduction means 64 sequentially reproduces the contents of the database means 5. Therefore, in this pattern sequential reproduction processing, the rhythm patterns stored in the database means 5 are reproduced in the order of addresses in the pattern table 63.

In this processing, first, the pattern table 6
The rhythm pattern corresponding to the address "1" of No. 3 is read from the database means 5 and reproduced. For example, in the case of the rhythm pattern table for rock music of FIG. 4, the rhythm pattern of the head address A-1 is read and reproduced, and in the case of the disc music pattern table of FIG. The rhythm pattern is read and played.

It is determined whether or not the reproduction of the read rhythm pattern is completed. When the reproduction is completed, it is determined whether the reproduced rhythm pattern is the pattern at the last address of the pattern table 63. If it is the last address pattern (YES), the process immediately returns. If it is not the last address pattern (NO), the rhythm pattern corresponding to the next address is read from the database means 5 and reproduced. The above processing is repeatedly executed until the rhythm pattern at the last address in the pattern table is reached.

As a result, it is possible to confirm all kinds of patterns stored in the database means 5. After that, if it is determined that there is no pattern desired by the user, work such as addition and editing may be performed. If you find a pattern you like, you can select it. Further, since the arrangement of patterns in the pattern table 63 or the database means 5 can be grasped, it can be expected to be important information for the user in selecting a pattern. It should be noted that this sequential reproduction processing is performed at the timing of the timer interrupt processing of FIG. In addition to the hard disk device, a mass storage device such as a magneto-optical disk device or a CD-ROM device may be used.
