DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument having an automatic musical performance function, and more particularly to a technique for automatically performing a musical performance by muting a sound of a predetermined part and a display technique for a display device of the electronic musical instrument.

[0002]

2. Description of the Related Art Conventionally, electronic musical instruments such as electronic pianos and electronic keyboards have been widely used. Many of these electronic musical instruments have a built-in automatic performance device. In this automatic performance device, automatic performance data of a plurality of parts (for example, a chord part, a bass part, a drum part, a melody part, etc.) are stored in a memory. Then, when the start of the automatic performance is instructed, the automatic performance data is sequentially read out from the memory, and the sound of each part is simultaneously generated based on the automatic performance data.

In recent years, electronic musical instruments have been developed which mute the sound of the melody part and generate only the sound of the other parts. Here, muting refers to suppressing sound generation, and is the same in the following. According to this electronic musical instrument, parts other than the melody part (for example, each part of a chord, a bass, and a drum) can be left to an automatic performance, and the melody part can be automatically performed in a performance mode in which the melody part is played by a keyboard device, for example. Therefore, the player can enjoy the ensemble by playing the melody or practice the melody performance.

However, in a conventional electronic musical instrument, the part that can be muted is fixed to the melody part, so that it is not possible to practice playing other parts.
In the following, an automatic performance performed by muting the sound of a predetermined part is referred to as “minus one performance”, and a part to be muted is referred to as a “mute part”.

In recent years, small electronic musical instruments having a small keyboard device and a small number of keys have been developed. When such an electronic musical instrument incorporates an automatic performance device, sounds generated by the automatic performance may include a sound having a pitch exceeding the key range of the keyboard device. Therefore, even if an attempt is made to perform minus one performance, the keyboard device may not be able to specify the sound of the mute part. For example, even if the sound of the bass part is muted and the practice of playing the bass part with the keyboard device is attempted, the keyboard device cannot specify the pitch of the bass part. This is also true for the other parts.

Also, when practicing ensemble with minus one performance, it is required to output the sound of each part from a separate output system, for example, from a headphone for a predetermined part and a speaker for another part. There is also.

An electronic musical instrument as described above generally has an operation panel provided with controls, indicators, a display device, and the like. The player gives various instructions to the electronic musical instrument by operating the controls on the operation panel. Here, the operating element refers to an object operated by a person, such as a switch, a slider, a jog dial, or the like.

By the way, as a switch mounted on the operation panel, a push button switch configured to have a toggle function is often used from the viewpoint of economy, design, operability, and the like. Since the on or off state of the push button switch is generally invisible from the outside, for example, an LED indicator is provided corresponding to the push button switch,
Thereby, it is often configured to display the on or off state of the push button switch.

[0009] However, depending on the function of the push button switch, even if the on or off state is known, it may not be sufficient by itself. For example, when a function of controlling whether or not a sound spreading effect (hereinafter, referred to as “3D effect”) is exerted is assigned to the push button switch, even if the on or off of the push button switch is known by the LED indicator, It is inconvenient to know how the extent of the sound is set.

On the operation panel of the electronic musical instrument, for example, letters, numbers, symbols,
An LCD display device capable of displaying figures and the like (hereinafter, collectively referred to as "characters") is used. In such an LCD display device, one character is represented by a display pattern of, for example, 8 rows × 6 columns, and various messages are displayed by combining a plurality of such characters.

However, in order to make it easy to visually recognize the display contents of the display device, there are cases where a message is displayed by enclosing it in a frame as shown in FIG. 17C, for example. In this case, for example, one row of dots is required to display the frame. However, since the display area of the message is limited to a predetermined range (in the example of FIG. 17C, a range of eight rows in the height direction), a character having a conventional display pattern is surrounded by a frame and displayed. Then, there is a problem that the message deviates from the display area.

[0012]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned various problems in the conventional electronic musical instrument, and a first object of the present invention is to provide an arbitrary part as a mute part for minus one performance. To provide an electronic musical instrument capable of performing the following.

A second object of the present invention is to provide an electronic musical instrument capable of performing minus one performance, in which a sound in a range of a mute part can be designated by a keyboard device having a small number of keys. .

A third object of the present invention is to provide an electronic musical instrument capable of performing minus one performance, which has an output system convenient for ensemble practice.

A fourth object of the present invention is to provide a display device of an electronic musical instrument that allows the user to easily visually recognize the setting state of a switch.

A fifth object of the present invention is to provide a display device of an electronic musical instrument which allows the display contents of the display device to be easily visually recognized without expanding the display area of the message.

[0017]

In order to achieve the first object, an electronic musical instrument according to the present invention includes a part for selecting an arbitrary part from among a plurality of parts in an electronic musical instrument for automatically performing a plurality of parts. It has a selection means, wherein the sound of the part selected by the part selection means is muted, the sounds of parts other than the part are generated, and the automatic performance is performed.

The part selecting means can be constituted by, for example, an operation panel. In this electronic musical instrument, if one part is selected by the part selecting means, the selected part becomes a mute part, the sound is muted, and the other parts are automatically played. As a result, a minus one performance is performed. Therefore, the player can practice the mute part by playing the selected mute part with, for example, the keyboard device of the electronic musical instrument or another musical instrument. In this electronic musical instrument, not only the melody part but also an arbitrary part, such as a chord part, a bass part, a drum part, etc., can be selected by the part selecting means and can be used as a mute part. Practice becomes possible.

A plurality of parts can be selected by the part selecting means. This makes it possible to practice in a complicated performance form. For example, when a melody part and a drum part are selected by the part selecting means and set as a mute part, for example, the chord part and the bass part are left to automatic performance, and the first player plays the melody using the keyboard device of the electronic musical instrument. It is possible to practice in a form in which a part is played and a second player plays a drum part using a drum set.

It should be noted that the mute part sound may be generated at a low volume rather than stopped at all. According to this configuration, the user can play the mute part while listening to the sound of the mute part as an example, so that the practice of the mute part is facilitated.

To achieve the second object, the electronic musical instrument of the present invention reads out automatic performance data of all parts from automatic performance data storage means storing automatic performance data of a plurality of parts, An electronic musical instrument that mutes a sound based on the automatic performance data of a specific part of the specified part, generates a sound based on the automatic performance data of the parts other than the specific part, and performs an automatic performance, wherein a note name indicating a note name Instruction means, and a sound range storage means for storing sound range information of a sound based on the automatic performance data of the specific part read from the automatic performance data storage means, and when an instruction is given by the pitch name indicating means In addition, a sound belonging to the sound range stored in the sound range storage means and having a sound name designated by the sound name designating means is generated.

As the note name indicating means, for example, a keyboard type note name indicating device (keyboard device), a guitar type note name indicating device, or any other device capable of indicating a note name can be used.

In this electronic musical instrument, the automatic performance data of all parts stored in the automatic performance data storage means is always read out when the automatic performance is started. However, the sound based on the automatic performance data of the specific part is muted, and only the sound generation based on the automatic performance data of the parts other than the specific part is performed. The specific part may be fixed to the melody part like a conventional electronic musical instrument, or may further include the above-described part selecting means, and may be selected by this part selecting means.

When the automatic performance data of the specific part is read, the sound range information of the sound specified by the automatic performance data, for example, the octave code is stored in the sound range storage means. The pitch range cannot be obtained from the pitch name indicating means, but only the pitch name. Then, when a predetermined pitch name is specified by the pitch name specifying means, one pitch is determined by the pitch range information and the pitch name stored in the pitch range storage means at that time, and a sound of this pitch is generated. .

For example, when the pitch name indicating means is a keyboard device having only 44 keys from the pitch F1 to the pitch C5, the sound of the pitch C1 (one octave from the sound that can be indicated by the keyboard device) is used in the automatic performance data. When the lower key is specified, the sound of the pitch C1 cannot be specified with a normal keyboard device. However, according to the electronic musical instrument of the present invention,
When the sound of the pitch C1 is designated by the automatic performance data, the octave code "1" as the range information is stored in the range storage means. Then, when the note having the pitch C2 is designated by the note name designation means, the sound having the pitch C1 is generated by the octave code "1" and the note name C. This is equivalent to shifting the pitch of the key C2 of the keyboard device one octave downward (key transposition).

As described above, according to this electronic musical instrument, the sound of the note name indicated by the note name indicating means is shifted upward or downward to the range to which the sound to be generated in the part whose sound is muted belongs. Therefore, when performing the minus one performance using the sound of the mute part as a model, it is possible to prevent a situation in which the sound of the mute part cannot be instructed by a keyboard device, for example.

In order to achieve the third object, the electronic musical instrument of the present invention mutes the sound of a specific part among a plurality of parts, generates sounds of parts other than the particular part, and thereby performs an automatic performance. An electronic musical instrument to be performed, comprising: a pitch instruction means for instructing a pitch; and a plurality of tone signal output means for outputting a tone signal, wherein each tone signal output means has a plurality of corresponding to each of the plurality of parts. It is characterized in that all or some of the tone signals in the group consisting of the tone signal and the tone signal based on the instruction of the pitch instruction means are output.

As the pitch indicating means, for example, a keyboard type note name indicating device (keyboard device), a guitar type note name indicating device, or any other device capable of indicating a note name can be used. The plurality of tone signal output means include, for example, a first system output circuit including an amplifier for supplying a tone signal to a speaker, an output terminal, and the like, and a second amplifier including an amplifier for supplying a tone signal to headphones, an output terminal, and the like. It can be constituted by a system output circuit or the like.

According to the electronic musical instrument of the present invention, for example, a musical tone of a part other than a specific part can be output to a speaker, and a musical tone of all parts can be output to headphones. Alternatively, the configuration may be such that the tone of a specific part is output to a speaker, and the tone of all parts is output to headphones.
Therefore, it is convenient for ensemble practice.

In order to achieve the fourth object, the display device of the electronic musical instrument of the present invention comprises an effect type designating unit for designating a type of a performance effect, and an effect degree designating unit for designating a degree to which the performance effect is applied. Display means; and a control means for displaying, on the display means, a graphic corresponding to the degree of applying the performance effect specified by the effect degree specifying means when a predetermined effect is specified by the effect type specifying means;
And characterized in that:

The effect type designating means can be constituted by, for example, operators on an operation panel. Examples of the effect specified by the effect type specifying unit include 3D, tremolo, chorus, reverb, equalizer, distortion, delay, rotary speaker, celeste, ensemble, phaser, flanger, and exciter.

The effect degree designating means can be constituted by, for example, an operator on an operation panel. As the operator, for example, a rotary volume, a slide volume, a jog dial, a wheel, a joystick, an up / down switch, a numeric key switch, a modulation wheel, a bender wheel, a foot switch, a foot volume, a keyboard, and the like can be used.

As the display means, an LCD display device, a CRT display device, and other various display devices capable of displaying graphics can be used.
As a graphic displayed on the display means, for example, when a 3D effect is designated as the effect type, a graphic (picture) expressing the state according to the degree of sound spread as shown in FIG. 14, for example. Can be used. By looking at the figure, the player can recognize at a glance that the effect of applying the 3D effect is currently set and the degree of the effect.

In order to achieve the fifth object, a display device for an electronic musical instrument according to the present invention is a display device for an electronic musical instrument for displaying a character in a predetermined display pattern. A sub character for displaying a sub display pattern which is a display pattern is further provided, and in a specific case, the sub display pattern is displayed using the sub character.

According to the present invention, one character is, for example, m lines ×
It is suitable for a display device of an electronic musical instrument that displays an n-row dot matrix. Usually, in order to secure a space between adjacent rows and adjacent columns, at least the outermost row or column of the dot matrix of m rows × n columns is not used for forming a display pattern. . Therefore,
The display pattern can be moved up, down, left, and right by at least one dot.

The present invention utilizes such characteristics of the display pattern. Now, paying attention only to the line, for example, when displaying the character “A” on the screen, the display pattern “A” is created using the dots from the first line to the (m−1) th line. In the present invention, separately from this, a display pattern “A ′” that is the same as the above “A” is created using the dots from the second line to the m-th line as the sub character “A ′”. That is, the display pattern “A ′” is a display pattern obtained by translating the display pattern “A” downward by one dot in parallel. In a specific case, for example, when displaying a character in a display pattern in which a horizontal line is drawn above the display pattern, the character is displayed using the sub character. Thus, for example, a character with a horizontal line drawn upward can be displayed without departing from the display area of the character.

Next, the operation of the electronic musical instrument of the first embodiment in the above configuration will be described with reference to the flowcharts of FIGS.

(1) Main Processing FIG. 5 is a flowchart showing the main processing of the electronic musical instrument. This main processing routine is started when the power is turned on. That is, when the power is turned on, first, an initialization process is performed (step S10). In this initialization process, the inside of the CPU 10 is reset, and buffers, registers, counters, flags, and the like defined in the work memory 12 are set to an initial state.

When the initialization process is completed, a panel process is performed (step S11). In the panel processing, processing corresponding to the operation of a switch on the operation panel 14, turning on / off of an indicator, and displaying a character on a display device are performed. Details of this panel processing will be described later.

Next, keyboard processing is performed (step S).
12). In this keyboard processing, sound generation processing, mute processing, and the like are performed. Through these processes, a musical tone corresponding to the operation of the keyboard device 16 is generated.

Next, automatic performance processing is performed (step S13). In this automatic performance processing, automatic performance data is read from the automatic performance data memory 17, and a tone is generated based on the read automatic performance data. Details of the automatic performance processing will be described later.

Next, "other processing" is performed (step S14). In this “other processing”, for example, processing for transmitting / receiving MIDI data to / from an external device via a MIDI interface circuit (not shown) is performed. Thereafter, the process returns to step S11, and the same processing is repeated thereafter.

As described above, when the panel operation or the keyboard operation is performed in the process of repeatedly executing the above-described steps S11 to S14 of the main processing routine, the processing corresponding to the operation is performed. Thus, various functions as an electronic musical instrument and an automatic performance device are realized.

(2) Panel Processing Next, details of the panel processing will be described with reference to the flowcharts of FIGS. This panel processing routine is called at regular intervals from the main processing routine.

In the panel process, first, a panel scan process is performed (step S20). In the panel scan process, switch data (hereinafter, referred to as “new switch data”) is read from the operation panel 14 via the panel interface circuit 13. Then, an exclusive OR operation of the switch data (hereinafter referred to as “old switch data”) read from the operation panel 14 in the previous panel processing and already stored in a predetermined area of the work memory 12 and the new switch data is performed. Is performed. This calculation result is stored in the work memory 1 as a panel event map.
2 in a predetermined area. Thereafter, the new switch data is stored in a predetermined area of the work memory 12 as old switch data.

Next, it is checked whether there is an ON event of the automatic performance setting switch APS (step S2).
1). This is performed by checking whether both the bit corresponding to the automatic performance setting switch APS in the panel event map and the bit corresponding to the automatic performance setting switch APS in the new switch data are on. The presence / absence of a switch ON event is checked in the same manner for other switches.

If it is determined that the automatic performance setting switch APS has an ON event, the automatic performance setting mode flag is set (step S21). As a result, the electronic musical instrument shifts to the automatic performance setting mode. Thereafter, the sequence returns to the main processing routine.
In this automatic performance setting mode, the function keys F1 to F
5 and the jog dial 140 are operated,
Various settings relating to automatic performance are performed. The automatic performance setting mode flag is cleared when the electronic musical instrument shifts to another mode.

If it is determined in step S21 that there is no ON event of the automatic performance setting switch, then,
It is checked whether there is a function key ON event (step S23). Here, when it is determined that there is an ON event of the function key, it is checked whether or not the automatic performance setting mode is set (step S).
24). This is performed by checking the automatic performance setting mode flag. Here, when it is determined that the automatic performance setting mode is set, it is checked whether there is an ON event of the function key F1 (step S2).
5). Then, when it is determined that there is an ON event of the function key F1, a process of decrementing the song number is performed (step S26). As a result, the content of the song number register is set to “−1”, and the resulting song number is displayed in the display area 142 of the display device 141.

When it is determined in step S25 that there is no ON event of the function key F1, or when the process of decrementing the song number is completed,
It is checked whether there is an ON event of the function key F2 (step S27). Then, when it is determined that there is an ON event of the function key F2, a process of incrementing the song number is performed (step S28). As a result, the content of the song number register is incremented by "+1", and the resulting song number is displayed in the display area 142 of the display device 141.

When it is determined in step S27 that there is no ON event of function key F2, or when the process of incrementing the song number is completed, it is then checked whether there is an ON event of function key F3 (step S29). . When it is determined that there is an ON event of the function key F3, an automatic performance start process is performed (step S3).
0). In this process, the automatic performance flag is set to "1". Also, the contents of the step time counter are cleared to zero. Also, the start address of the automatic performance data memory 17 storing the automatic performance data of the music set in the song number register is set in the address register, and the step time STEP in the note data specified by the address is set. It is read and set in the step time register. Thereby, an automatic performance process (details will be described later) is started.

When it is determined in step S29 that there is no ON event of the function key F3, or when the automatic performance start process is completed, it is then checked whether there is an ON event of the function key F4 (step S31). When it is determined that there is an ON event of the function key F4, an automatic performance stop process is performed (step S32). In this process, the automatic performance flag is cleared to "0". Thereby, the automatic performance processing (details will be described later) is stopped.

If it is determined in step S31 that there is no ON event of the function key F4, or if the automatic performance stop processing is completed, then it is checked whether there is an ON event of the function key F5 (step S33). Then, when it is determined that there is an ON event of the function key F5, a mute part setting mode flag is set (step S34). As a result, the electronic musical instrument shifts to the mute part setting mode. Thereafter, the sequence returns to the main processing routine. Also, if it is determined in step S33 that there is no ON event of the function key F5, the sequence returns to the main processing routine.
In this mute part setting mode, jog dial 140
Is operated, the part to be muted is determined. The mute part setting mode flag is
Cleared when the electronic musical instrument has shifted to another mode.

If it is determined in step S23 that there is no function key ON event, it is checked whether there is an event of the jog dial 140 (step S35). This is performed by checking whether or not the dial data in the panel data indicates that a displacement has occurred. Then, when it is determined that there is an event of the jog dial 140, it is then checked whether or not the mute part setting mode is set (step S36). This is the mute part setting mode. This is done by examining the flags. If it is determined that the mode is the mute part setting mode, a mute part update process is performed (step S37). That is, the contents of the mute part register are incremented by "+1" or "-1" according to the dial data. Thereby, a mute part is determined. The contents of this mute part register are referred to in the automatic performance processing described later. afterwards,
The sequence returns to the main processing routine. If the mute part setting mode is not set in step S36, the sequence returns to the main processing routine.

At step S35, the jog dial 14 is
If it is determined that there is no event of “0”, “other switch processing” is performed (step S38). In this processing, processing of various switches (not shown) is performed. Thereafter, the sequence returns to the main processing routine.

(3) Automatic Performance Process Next, details of the automatic performance process will be described with reference to the flowchart of FIG. This automatic performance processing routine is called at regular intervals from the main processing routine.

In the automatic performance processing, first, it is checked whether or not the automatic performance flag is "1" (step S4).
0). Here, if it is determined that the automatic performance flag is not "1", that is, that the automatic performance is stopped, the sequence returns to the main processing routine. Thereby, a function of stopping the automatic performance is realized.

On the other hand, when it is determined that the automatic performance flag is "1", it is recognized that the automatic performance is currently being performed, and
It is checked whether it is the timing for reading out the automatic performance data (step S41). Here, the read timing means a timing that arrives every time one step time elapses. Whether or not this read timing has arrived
For example, the determination is made by referring to the time measured by a clock mechanism (not shown). If it is determined in this step S41 that it is not the read timing, the sequence returns to the main processing routine. With this processing, the automatic performance processing is performed at intervals of one step time.

If it is determined in step S41 that it is the read timing, then the step time STEP set in the step time register is compared with the content COUNT of the step time counter. Here, if it is determined that they do not match, it is recognized that the note data having the step time STEP has not reached the sounding timing yet. Therefore, in this case, only the process of incrementing the content COUNT of the step time counter is performed (step S43), and then the sequence returns to the main processing routine.

On the other hand, when it is determined that the comparison results match, 5-byte data is read from the position of the automatic performance data memory 17 specified by the address set in the address register at that time. Then, it is determined whether the data is note data or end data. This is performed by examining the MSB of the first byte. If it is determined that the data is note data, then it is checked whether the data is note data of a mute part (step S4).
6). This is performed by checking whether the part number of the first byte of the note data matches the part number stored in the mute part register. Here, when it is determined that the read note data is not the note data of the mute part, a sound generation process is performed (step S47), and when it is determined that the note data is the note data of the mute part, the sound is generated. Processing is skipped. Thus, a function of muting the sound of the part specified by the player is realized.

In the above tone generation process, tone color parameters are read from the program memory 11 based on the key number and velocity in the note data and the tone color selected at that time, and the tone color parameter is designated by the note data part number. Sound source 1 assigned to the part to be played
It is sent to 9 sounding channels. As a result, a tone signal based on the tone color parameter is generated in the sounding channel, and the tone signal is generated by the amplifier 20 and the speaker 21.
Are sequentially transmitted to generate a musical tone. The mute is performed by searching for a sound channel in the sound source 19 whose gate time has become zero by a silence processing routine (not shown) and sending predetermined data to this sound channel.

Next, the step time STEP in the next note data is read out and set in the step time register (step S48). The next note data is read from the position of the automatic performance data memory 17 designated by the address obtained by adding "+5" to the contents of the address register. Thereafter, the sequence returns to step S42,
Hereinafter, the same processing is repeated. By this repetition processing, note data having the same step time STEP is sequentially read from the automatic performance data memory 17, and a tone based on the read note data is generated.
Then, when note data having a step time STEP different from the content of the step time counter is read, the content of the step time counter is incremented (step S43), and the sequence returns to the main processing routine.

On the other hand, if it is determined in step S45 that the data is end data, an end process is performed (step S49). In this end processing, the automatic performance flag is cleared to "0" in the case of an electronic musical instrument of a specification in which the music is played only once and the automatic performance is finished. In the case of an electronic musical instrument that is designed to automatically play a song repeatedly, the contents of the step time counter are cleared to zero and the automatic performance data memory that stores the automatic performance data of the song set in the song number register. The 17th head address is set in the address register, and the step time STEP in the note data specified by the address is read out and set in the step time register. Thereby, the automatic performance process is restarted. It should be noted that the operation panel 14 may be configured to be able to set whether the automatic performance is performed only once or repeatedly. Then, step S
Returning to 42, the same processing is repeated thereafter.

As described above, according to the electronic musical instrument of the first embodiment, the player can set any part as a mute part, so that he can practice any part with automatic performance as a back. It becomes possible.

Although the first embodiment has described the case where only one mute part is provided, it is also possible to provide two mute parts.
In this case, for example, a key similar to the function key F5 is further provided, and the second mute part is designated using this key and the jog dial 140 in the same manner as the function key F5. The designated second mute part is stored in a further provided second mute part register. Then, in step S46 of the automatic performance processing routine, it is checked whether or not the part number of the musical note data matches any of the contents of the mute part register and the second mute part register. (Step S47) may be configured to be skipped. In the same way, add 3 mute parts
It is also possible to configure such that at least one is provided.

(Embodiment 2) In the electronic musical instrument of Embodiment 2, the key pitch of the keyboard device 16 is transposed in octave units in accordance with the note number of the note data included in the automatic performance data.

The configuration of the electronic musical instrument of the second embodiment is the same as that of the electronic musical instrument of the first embodiment (the block diagram of FIG. 1). Keyboard device 16 to keyboard interface circuit 1
The handling of the key data obtained via the electronic musical instrument 5 differs depending on whether the electronic musical instrument operates in the normal mode or in the automatic performance mode. That is, in the case of the normal mode, both the octave code and the note name code obtained from the key data are used for sound generation, whereas in the automatic performance mode, only the note name code is used for sound generation. The octave code for the automatic performance mode is obtained from the octave register.

In the second embodiment, an “octave register” is further defined in the work memory 12. The octave register stores the octave code of the currently sounding sound. This octave register is set according to the read automatic performance data in the automatic performance processing routine. It is preferable that the contents of the octave register are always displayed on the display device 141 in the automatic performance mode. As a result, the player can recognize which octave sound is currently being generated, and the performance is facilitated.

(1) Main Processing The main processing according to the second embodiment is the same as the above-described processing except that the initial value of the octave register is set to “3” in the initialization processing (step S10). This is the same as the main processing of the first embodiment (see FIG. 5). By setting “3” in the octave register, in the initial state of the automatic performance mode, even if any key is pressed, the pitches C3 to C3 are set.
The sound is generated at the pitch in the range of B3.

(2) Panel Processing The panel processing of the second embodiment is the same as that of the first embodiment.
(See FIGS. 6 and 7).

(3) Keyboard Processing The details of the keyboard processing will be described with reference to the flowchart of FIG. This keyboard processing routine is called at regular intervals from the main processing routine.

In the keyboard process, first, a key scan process is performed (step S50). In this key scanning process,
Key data (hereinafter, referred to as “new key data”) is read from the keyboard device 16 via the keyboard interface circuit 15. Then, the keyboard device 16 is used in the previous keyboard processing.
, And an exclusive OR operation of the key data (hereinafter referred to as “old key data”) already stored in a predetermined area of the work memory 12 and the new key data is performed. The calculation result is stored in a predetermined area of the work memory 12 as a key event map. Thereafter, the new key data is stored in a predetermined area of the work memory 12 as old key data.

Next, it is checked whether or not there is a key pressing event (step S51). This is performed by checking whether or not a bit in the new key data corresponding to an on bit in the key event map is on.

If it is determined that there is a key press event, then a note number is calculated (step S52). When the electronic musical instrument is in the automatic performance mode, the note number is obtained by synthesizing an octave code stored in the octave register with a note name code created based on the key code obtained from the keyboard device 16. Is calculated by When the electronic musical instrument is in the normal mode, the note number is calculated based on the key code obtained from the keyboard device 16.

Next, a tone generation process is performed (step S).
53). In this tone generation process, tone parameters are read from the program memory 11 based on the note number, touch data, and the tone selected at that time, and the tone parameters are assigned to the tone generator assigned to the keyboard device 16 for tone generation. Sent to 19 sounding channels. As a result, a tone signal based on the tone color parameter is generated in the sounding channel, and the tone signal is sequentially transmitted to the amplifier 20 and the speaker 21 to generate a sound based on a key operation. Thereafter, the sequence returns to the main processing routine.

If it is determined in step S51 that there is no key press event, then it is checked whether there is a key release event (step S54). This is performed by checking whether the bit in the new key data corresponding to the bit being turned on in the key event map is turned off. Here, if it is determined that there is a key release event, a mute process is performed (step S55). In the mute processing, predetermined data is stored in the keyboard device 16.
Is sent to the sound channel of the sound source 19 assigned for sound generation of the sound source. As a result, the sound being generated in the sound channel is muted. Thereafter, the sequence returns to the main processing routine. If it is determined in step S54 that there is no key release event, it is recognized that there is no key event, and the sequence returns to the main processing routine.

(4) Automatic Performance Processing Next, details of the automatic performance processing of the second embodiment will be described with reference to the flowchart of FIG.

The automatic performance process of the second embodiment is the same as the automatic performance process of the first embodiment (FIG. 8) except that step S60 is added. That is, if it is determined in step S46 that the note data is the note data of the mute part, the sound generation processing is not performed and the octave code generation processing is performed (step S60). That is, an octave code of the octave to which the note number included in the note data belongs is generated and stored in the octave register.

Therefore, when the keyboard device 16 is operated to generate a sound thereafter, the contents of this octave register are used as octave codes. Therefore, according to this electronic musical instrument, the pitch of the keyboard device 16 is shifted upward or downward to the range of the sound to be generated in the mute part. Furthermore, it is possible to prevent a situation in which the pitch cannot be specified.
