Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument capable of performing with a variety of rhythm sound sources using as few operators as possible.

[Summary of the Invention]

The present invention relates to an electronic musical instrument capable of performing a rhythm,
When assigning assignment information indicating the type of rhythm sound source to a performance control, the type of rhythm sound source to be assigned is changed by repeatedly operating the performance control, so that a large number of rhythm sound source types can be assigned. A desired rhythm sound source can be easily assigned to the performance operator.

[Conventional technology]

Conventionally, as an electronic musical instrument of this kind, there has been proposed an electronic musical instrument in which one of a plurality of rhythm sound sources can be assigned to a key by operating one of the keys constituting the upper keyboard. (JP-A-61-282896).

This conventional configuration selects each rhythm sound source in that an arbitrary rhythm sound source can be assigned to each key of a keyboard portion used when playing the main musical tone, which is essentially a melody portion and an accompaniment portion. There is an advantage that the configuration as a whole can be simplified as compared with a case in which dedicated selection operators for exclusive use are separately provided.

[Problems to be solved by the invention]

However, if keys are assigned one by one as performance operators for selecting a rhythm sound source, a large number of keys are required to specify the type of the rhythm sound source, and the overall configuration is still complicated. In addition, when performing, the performer needs the troublesome task of selecting and operating one of a number of rhythm sound sources arbitrarily assigned. There is a problem that cannot be easily solved.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has been made so that a large number of rhythm sound sources can be easily changed as necessary by using a small number of performance operators that can be selected easily in practice. It is intended to propose musical instruments.

[Means for solving the problem]

In order to solve such a problem, in the present invention, a plurality of performance operators PAD1 to PAD4, each of which generates operation information in accordance with an operation of a player, and a type of a rhythm sound source to be assigned to each of the plurality of performance operators. Rhythm sound type group storage means 26 for storing a plurality of groups of rhythm sound type information to be represented by a plurality of pieces of information that do not include the same rhythm sound source in different groups, and rhythm sound type group storage Group selecting means PA for selecting a desired group from a plurality of groups stored in the means
DA, PTIX, rhythm sound type information indicating the type of rhythm sound source assigned to the performance operator as assignment information storage means REG3, and assigned to the performance operator in response to operation of the performance operator A registration means SP21 is provided for changing the rhythm sound type information to be performed within the group selected by the group selection means and for registering the changed rhythm sound type information as assignment information in the assignment information storage means.

[Action]

When the assignment information registration means (PADA) is operated, the type of the sound source corresponding to the performance operation means (PAD1 to PAD4) is registered in the assignment information storage means (6, REG3). At that time, every time the performance operators (PAD1 to PAD4) are operated,
By changing the type of rhythm sound source to be assigned, a desired rhythm sound source can be assigned from a large number of rhythm sound source types by a simple operation as needed.

〔Example〕

 An embodiment of the present invention will be described below in detail with reference to the drawings.

[1] First Embodiment (1) Configuration of First Embodiment In FIG. 1, reference numeral 1 denotes an electronic musical instrument as a whole, which has a keyboard section 2 and a percussion instrument section 3 as a performance operation section and a setting operation section. The central processing unit (CPU 6) of the data processing unit 5 having, for example, a microcomputer has an operation panel unit 4, and input information obtained by operating the keyboard unit 2, the percussion instrument unit 3, and the operation panel unit 4 is constituted by a ROM. In accordance with the program in the program memory 7, the data is fetched via the bus 9 using the working memory 8 and the main routine RT0 shown in FIG. 2 is executed to thereby register the register 25 (FIG. 3) of the data storage unit 10; Data is processed using the sound source number memory 26 and the rhythm data memory 27,
It is stored or transmitted to the tone signal generator 11.

Key information S1 corresponding to each key of the keyboard unit 2 is taken into the data processing unit 5 via the bus 9 from the key switch circuit 21.

In the case of this embodiment, the percussion instrument section 3 comprises a plurality of pads PAD1 to PAD4, for example, four pads PAD1 to PAD4 arranged on a board 3A, and a performance operator 3B
When the pads PAD1 to PAD4 are operated (that is, when a pad-on event occurs), a pad switch signal S2 corresponding to the pad number is sent from the pad switch circuit 22 to the data processing unit 5 via the bus 9. At the same time, the pad touch detection data S3 indicating the strength of the performance operation for the pads PAD1 to PAD4 is transmitted from the pad touch detection circuit 23 to the data processing unit 5 via the bus 9.

When the CPU 6 receives the pad switch signal S2,
The pad switch subroutine RT2 (FIG. 4) is executed.

The operation panel section 4 has a start switch ST, a file switch FIL, a pad sign switch PADA, and other operators OPR.

The start switch ST is provided with a start switch on event subroutine RT3 (FIG. 6) by inputting a start switch signal S4 to the CPU 6 when the rhythm performance is pressed or pressed by the player when starting or ending the rhythm performance.
It has the basic function of inputting an execution instruction.

The file switch FIL receives an instruction to execute a file-in on event RT4 (FIG. 7) by inputting a file-in switch-on signal S6 to the CPU 6 when pressed by a player during a rhythm performance. Has the basic function of inputting.

Patsudo Ainitsu Switch PADA is the pad of the percussion instrument part 3.
In addition to PAD1 to PAD4 as their original function, that is, a function as an operation input means for generating a percussion instrument sound, a start switch is provided for each pad PAD1 to PAD4 as necessary.
It operates so that the player can designate an operation mode in which the ST functions as a start switch, or instead of the file switch FIL, as a file switch, or functions as a rhythm sound source selection means. When the switch is turned on, the operator switch circuit 24 sends out the pad sign switch signal S6.

Other operators OPR input an operator ON signal S7 including a volume, tone, rhythm selection, and effect signal from the operator switch circuit 24 to the CPU 6 in accordance with the player's operation.

The CPU 6 executes the main routine RT0 shown in FIG. 2 to give the main musical sound generation information S11 to the keyboard musical sound signal generating circuit (TG1) 28 based on the key information S1 to provide the main musical sound signal S1.
In addition to generating 2, the rhythm sound generation circuit (TG2) 29 is provided with rhythm sound generation information S13 based on the setting operation of the operation panel section 4 and the performance operation of the pads PAD1 to PAD4 of the percussion instrument section 3. A rhythm sound signal S14 is generated. Thereby, a musical sound is generated from the sound system 32 having the amplifier circuit 30 and the speaker 31.

Here, the rhythm sound generation information S13 is output from the tempo oscillator 33 while the CPU 16 executes the rhythm select subroutine (FIG. 8) based on the operator ON signal S7 obtained from the rhythm selection switch included in the other operators OPR. Rhythm interrupt signal S16 supplied with tempo information S15
Is generated by executing a rhythm interrupt subroutine (FIG. 9).

(2) Main Routine When the CPU 6 enters the main routine RT0, the processing step RT1 is executed.
, An initial setting process is performed. At this time, the data of the register 25 is initialized.

Subsequently, the CPU 6 executes a pad switch event subroutine in the next processing step RT2. This subroutine, as shown in FIG.
When the pad switch signal S2 is generated by operating PAD1 to PAD4, the player switches the start switch ST,
File Switch FIL, Patch Door Sign Switch PADA
A start switch function to start or end rhythm performance for pads PAD1 to PAD4 by tapping pads PAD1 to PAD4 with a stick while turning on while simultaneously combining And a process of assigning a rhythm sound source of a percussion instrument sound used for rhythm performance.

Subsequently, the CPU 6 executes a start switch-on event subroutine in a processing step RT3. In this step, as shown in FIG. 6, processing for starting or ending the rhythm performance is executed.

Next, the CPU 6 shifts to a processing step RT4 to execute a file installation event subroutine. This step RT4 executes the insertion process in the file-in mode as shown in FIG.

Subsequently, the CPU 6 shifts to a processing step RT5 and executes a rhythm select subroutine. At this time, the CPU 6 executes a subroutine shown in FIG.

Thus, the CPU terminates the processing of the data relating to the rhythm performance, and sets other processing in processing step RT6, for example, processing of key information S1 obtained in the key switch circuit 21, and setting of other operation elements OPR of the operation panel section 4. After executing the processing of the tone etc.,
Return to

Thus, the CPU 6 repeats the processing of steps RT2 to RT6 thereafter, thereby obtaining the key information S1 fetched from the key switch circuit 21, the pad switch signal S2 fetched from the pad switch circuit 22, and the pad touch detection data fetched from the pad touch detection circuit 23. S3, a start switch-on signal S4, a file-in switch-on signal S5, a pad sign switch signal S6, and a switch-on signal S7, which are fetched from the operation switch circuit 26, are used to generate a sound channel and a sound channel for the key information S1. Data processing is sequentially performed for each of the sounding channels of the pads PAD1 to PAD4, so that the main musical sounds having the number of sounds that can be simultaneously sounded as a whole and the rhythm sounds of the pads PAD1 to PAD4 are practically simultaneously sounded.

(3) Pad switch-on event subroutine CPU6 sets pad switch-on event subroutine RT2
Upon entering (FIG. 4), it is first determined in step SP1 whether or not an on-event has occurred in the i-th pad PAD (i) (i = 1, 2, 3, 4), and a negative result is obtained. If not, the process returns to the main routine from step SP2 without performing any processing.

On the other hand, if a positive result is obtained in step SP1, the CPU 6 moves to step SP3 and the pad PAD (i)
Register the pad touch detection data S3 obtained for
After writing and holding the pad-specific touch data REGREG (i) in the pad-specific touch data register REG2 of FIG. 25 (FIG. 3), the process proceeds to step SP4.

In this step SP4, the CPU 6 determines whether or not the pad sign switch PADA is simultaneously turned on.

If a positive result is obtained here, this means that the player performs an operation for assigning a start switch function, a file switch function, and a sound source selection switch function necessary for rhythm performance to the pad PAD (i). However, if a negative result is obtained, it means that these assignment operations are not performed.

Therefore, if a positive result is obtained in step SP4, the CPU 6 proceeds to step SP5 to determine whether or not the start switch ST is simultaneously turned on.

If an affirmative result is obtained here, this means that the player is about to switch the switch function assigned to the pad PAD (i), and at this time, the CPU 6 moves to step SP6 to register 25 (third register). The start switch function assignment pad number data STREG is read out from the start switch function assignment pad number register REG6 of FIG. 9 to check whether or not the content is the value i.

If a positive result is obtained here, this means that a function as a start switch has been assigned to the pad PAD (i), and at this time, the CPU 6 moves to step SP7 and assigns a start switch function assignment patch. By rewriting the number data STREG to the value 0, the start switch function assigned to the pad PAD (i) is released, and the routine goes to step SP8.

In this embodiment, since the number of pads is four, the pad numbers are i = 1 to 4, whereas i = 4.
0 Start switch function allocation pad number data STRE
By writing to G, the start switch function can no longer be assigned to any of the pads PAD1 to PAD4.

This step SP8 is a sound generation routine, and CPU6 is register 2
The i-th pad-specific touch data VOLEG stored in the pad-specific touch data register REG2 of FIG. 5 (FIG. 3).
(I) and the i of the pad assigned sound source number register REG3
After transmitting the pad-assigned sound source number data TONE (i) to the rhythm sound signal generation circuit (TG2) 29, the process returns to the main routine from step SP2.

At this time, the rhythm sound signal generation circuit (TG2) 29 outputs the sound system with the sound volume represented by the pad-specific touch data VOLREG (i) for the rhythm sound source represented by the pad assigned sound source number data TONE (i). Generate a rhythm sound from 32.

On the other hand, if a negative result is obtained in step SP6 described above, this indicates that the i-th pad P has been stored as the start switch function assignment pad number data STREG.
This means that AD (i) has not been assigned. At this time, the CPU 6 proceeds to step SP9, rewrites the start switch function assignment pad number data STREG to a value i, and then proceeds to step SP8.

In this way, when the player simultaneously turns on the pad sign switch PADA (step SP4) and the start switch ST (step SP5), the CPU 6 changes the assigned state of the start switch function of the i-th pad PAD (i). rewrite.

Next, if a negative result is obtained in the above-mentioned step SP5, this means that the player intends to assign a function other than the stop switch function, that is, the file switch function or the sound source selection switch function to the ith pad PAD (i). Means that.

At this time, the CPU 6 proceeds to step SP11 to determine whether or not the file switch FIL is simultaneously turned on. If a positive result is obtained here, this means that the player
Means that the file switch function is to be assigned to the pad P (i).
Is transferred to step SP12, the file switch function assignment pad number data FILREG held in the file switch function assignment pad number register REG7 of the register 25.
Is determined as to whether or not the content is a value i.

If a positive result is obtained here, the i-th corresponding pad PA
This means that a function as a file switch has already been assigned to D (i). At this time, the CPU 6 proceeds to step SP13 to rewrite the file switch function assignment pad number data FILREG to a value 0. ,
In the same way as with the start switch function, the pad
After releasing the file switch function assigned to PAD (i), the process returns to the main routine via steps SP8 and SP2.

On the other hand, if a negative result is obtained in step SP12, this means that the i-th pad PAD (i) has hitherto been used.
Means that the file switch function has not been assigned to the file. At this time, the CPU 6 moves to step SP14 and the file switch function assignment pad number data FI
After rewriting LREG to the value i, the process returns to the main routine via steps SP8 and SP2.

In this way, the CPU 6 rewrites the file switch function assignment state for the i-th pad PAD (i) when the player simultaneously turns on the pad sign switch PADA and the file switch FIL. Execute

Next, if a negative result is obtained in step SP11, this means that the player is about to assign the function as the sound source selection switch to the i-th pad PAD (i).

Then, the CPU 6 proceeds to step SP21 and registers 25 (third
After adding "+1" to the pad assigned sound source number data TONE (i) of the pad assigned sound source number register REG3 in FIG. 7), the addition result is rewritten as new pad assigned sound source number data, and the routine proceeds to step SP22.

Here, the pad assigned sound source number data TONE (i) is
The rhythm sound source numbers (0 to 15 in this embodiment) that can be assigned to the i-th pad PAD (i).

In this step SP22, the pad assigned sound source number data TONE (i) after the addition of "+1" is set to a value 16 which exceeds the maximum number of sound sources.
In the step of judging whether or not the above is true, if a negative result is obtained, the process immediately returns to the main routine through steps SP8 and SP2, whereas if an affirmative result is obtained, the process proceeds to step SP23 to perform padding. After rewriting the assigned sound source number data TONE (i) to the value 0, the steps SP8, S
Return to the main routine via P2.

Thus, the CPU 6 can be used by the performer
When only the DA is turned on, the i-th pad PA
By hitting DA (i) with the stake, a process of re-designating the sound source of the next sound source number following the sound source number specified so far is executed for this pad PAD (i).

In the case of this embodiment, the rhythm sound signal generation circuit (TG2) 2
Reference numeral 9 indicates that 16 rhythm sound sources can be selected and designated. For example, pad assigned sound source number data TONE (i)
When the value is 0, 1, 2,..., 15, a bass drum, a snare drum, a conga,... A hi-hat closed rhythm sound can be designated as the rhythm sound source, and thus the pad PAD (i) is hit. Each step SP21
In step SP23, when the sound source number which advances by "+1" is assigned to the pad PAD (i), and the sound source number eventually exceeds the maximum number of sound sources 15 and becomes 16, the sound source number of the sound source number 0 is determined in step SP23. By returning the pad assigned sound source number data TONE (i) to the sound source, it is possible to specify again from the 0th to the 15th.

In this way, the pad assign switch PADA pads the pad assigned sound source number data TONE (1) to TONE (4), which is the assignment information indicating the type of rhythm sound source to be assigned to the pads PAD1 to PAD4 as the performance operators. The assigned sound source number register REG3 operates as an assignment information storing means for storing and registering the assigned sound source number register REG3.

Next, if a negative result is obtained in step SP4, this indicates that the player has not tried to assign the start switch function, the file switch function, and the sound source selection switch function to the i-th pad PAD (i). At this time, the CPU 6 proceeds to step SP31 and
It is determined whether or not the value of the file switch function assignment pad number data FILREG of the file switch function assignment pad number register REG7 of FIG. 25 (FIG. 3) is i.

If a positive result is obtained here, this means that the player is about to insert a fill-in performance in the rhythm performance that is currently ongoing. At this time, the CPU 6 shifts to step P32, where the file flag FILFG of the file flag register REG10 of the register 25 (FIG. 3) is stored.
, And the result of the operation is rewritten as new file-in flag data FILFG.

Thus, when the previous file-in flag data FILFG is logic "1" (or logic "0"), the new file-in flag data FILFG is inverted to logic "0" (or logic "1"). Is switched to.

Subsequently, the CPU 6 determines in step SP33 whether the rewritten file-in flag data FILFG is logic "1", and when an affirmative result is obtained, moves to step SP34 to register 25 (FIG. 3). After transferring the rhythm volume data RHYVOL2 of the rhythm volume data register REG5 to the rhythm volume data temporary save register REG4 as the rhythm volume data temporary save data RHYVOL1, the padded touch data VOLREG (i) is added as new rhythm volume data RHYVOL2. Then, the rhythm volume data RHYVOL2 is transmitted to the rhythm sound signal generation circuit (TG2) 29 as rhythm sound generation information S13.

Thus, in step SP34, the rhythm volume data RHYVOL2 representing the volume of the rhythm sound that has been generated in the rhythm sound signal generation circuit (TG2) 29 is temporarily saved as rhythm volume data temporary saving data RHYVOL1. i-th pad PAD
New pad-specific touch data VOLREG representing the pad touch detection data S3 obtained by operating (i).
By rewriting (i) to the rhythm volume data RHYVOL2, the latest pad touch detection data S3
The volume of the rhythm sound is changed to the volume corresponding to.

On the other hand, when a negative result is obtained in step SP33, the CPU 6 shifts to step SP35 to store the rhythm volume data temporary save data RHYVOL1 which has been held in the rhythm volume data temporary save register REG4.
Is rewritten as rhythm volume data RHYVOL2 of the rhythm volume data register REG5, and then the rhythm volume data RHYVOL2 is converted to a rhythm sound signal generation circuit (TG2).
29, and is transmitted as rhythm sound generation information S13.

Thus, the CPU 6 controls to generate a rhythm sound at the volume of the previous rhythm volume data temporarily held as rhythm volume data temporary save data RHYVOL1.

As a result, by hitting the pad PAD (i) to which the file-in is assigned once in step SP34, the CPU 6 adjusts the volume of the file-in performance to the pad PAD (i) according to the intensity of the performance operation amount given to the pad-PAD (i). When the same pad PAD (i) is hit at an arbitrary time thereafter, the volume of the file-in performance can be returned to the original volume in step SP35.

As a result, a lively file-in performance can be achieved according to the player's preference.

When the processing in step SP34 or SP35 is completed, or when a negative result is obtained in step SP31, the CPU 6 shifts to step SP41. In this step SP41, the rhythm running flag RUN of the rhythm running flag register REG8 of the register 25 (FIG. 3) is logic "0" (this means that the rhythm is not in the rhythm playing state), and the start switch function is assigned. It is determined whether or not the content of the start switch function assignment pad number data STREG of the pad number register REG6 is a value i.

If a positive result is obtained here, this means that the start switch function is assigned to the pad PAD (i), but the rhythm performance has not started at the present time, and the CPU 6 proceeds to step SP42. To execute the start subroutine.

When the start subroutine SP42 is entered, the CPU 6
As shown in the figure, in step SP43, the rhythm running flag data RUN is rewritten to data of logic "1".
After the tempo count register REG9 is reset by rewriting the tempo count data TCNT of the tempo count register REG9 of the register 25 (FIG. 3) to a value "0", the pad switch-on event subroutine RT2 (FIG. ) By returning to step SP8,
Return to the main routine via SP2.

Thus, when the CPU 6 confirms that the start switch function has been assigned to the i-th pad PAD (i) and that the rhythm performance has not started, the CPU 6 resets the state to the rhythm performance start.

On the other hand, if a negative result is obtained in step SP41, this means that the pad PAD (i) is already in the automatic rhythm playing state in a state where the start switch function is assigned to the pad PAD (i), or the pad PAD (i)
(I) means that the start switch function is not assigned. At this time, the CPU 6 does not need to start the rhythm performance, so jumps to step SP42 and returns to the main routine via steps SP8 and SP2.

(4) Start switch-on event subroutine CPU6 uses the start switch-on event subroutine RT
Step 3 (FIG. 6) is performed as follows.

That is, the CPU 6 determines whether or not an on-event has occurred in the start switch ST in step SP51, and determines whether or not the pad sign switch PADA is simultaneously turned on in step SP52 when a positive result is obtained. .

If a negative result is obtained here, this means that the player has only turned on the start switch ST (not turned on the file switch FIL and the pad sign switch PADA). At this time, the CPU 6 determines whether or not the rhythm running flag RUN is logic "1" in step SP53, rewrites the rhythm running flag data RUN to logic "0" when an affirmative result is obtained, and then proceeds from step SP55. Return to the main routine.

On the other hand, if a negative result is obtained in step SP53, the rhythm performance is started by rewriting the rhythm running flag data RUN to logic "1" and resetting the tempo count data TCNT to the value 0 in step SP56. Then, the process returns to the main routine from step SP55.

In this way, the start switch ST
Only the pad PAD
When (i) is operated, if it is in the rhythm playing state before (or not in the rhythm playing state),
The CPU 6 ends (or starts) the rhythm performance.

On the other hand, when a negative result is obtained in step SP51 and when a positive result is obtained in step SP52, steps SP52, SP53, SP54 and SP are respectively performed.
Jump to 53 and SP54 and return to the main routine from step SP55.

(5) File Switch On Event Subroutine In the file switch on event subroutine RT4 of the main routine RT0 (FIG. 2), the CPU 6 generates an ON event in the file switch FIL at step SP61 as shown in FIG. It is determined whether or not the pad sign switch PADA has been turned on at the same time in step SP62 when a positive result is obtained, and when a negative result is obtained in step SP63.
After inverting the contents of the file-in flag data FILFG at step SP64, the process returns to the main routine from step SP64.

Thus, the CPU 6 inverts the content of the file-in flag data FILFG every time the file-in switch FIL is turned on, thereby terminating the file-in performance when the file-in performance is performed (or not performed) (or Start).

On the other hand, when a negative result is obtained in step SP61 and when a positive result is obtained in step SP62, the steps SP62, SP63, and SP63 are jumped, respectively, and the process returns to the main routine from step SP64.

(6) Rhythm select subroutine In step SP71 of the rhythm select subroutine RT5 (FIG. 8) of the main routine RT0 (FIG. 2), the rhythm select switch and file in included in the other operators OPR of the operation panel unit 4 It is determined whether or not an ON event has occurred in the switch FIL, and if an affirmative result is obtained, the process proceeds to step SP72 where a pattern memory (rhythm pattern data memory 27 (first 1), the designated rhythm pattern is sent to the rhythm sound signal generation circuit (TG2) 29 as rhythm sound generation information S13, and then the main routine is executed from step SP73. Return.

On the other hand, when a negative result is obtained in step SP71, the CPU 6 jumps to step SP73 and ends the subroutine.

(7) Rhythm interrupt subroutine In this way, the CPU 6 causes the main routine RT0 (FIG. 2)
When the rhythm interrupt signal S16 is generated from the tempo generator 33 while the loop of FIG.
6 enters the control state of the rhythm performance by executing the rhythm interrupt routine RT10 shown in FIG.

CPU 6 sets the rhythm running flag data in step SP75.
It is determined whether or not RUN is logic "1". If an affirmative result is obtained (this means that the rhythm is currently being played), the flow moves to step SP76 to enter the file-in flag data FI.
The rhythm sound generation information S13 determined according to the LFG, the tempo count data TCNT, and the rhythm type specified in the rhythm select subroutine RT5 (FIG. 8) is transmitted to the rhythm sound signal generation circuit (TG2) 29. A rhythm sound of a normal pattern or a rhythm sound of a file-in pattern is generated.

Subsequently, the CPU 6 proceeds to step SP77 to add “+1” to the tempo count data TCNT, and proceeds to step SP78 to add “+”.
1 "Tempo count data TCNT obtained as a result of addition is a value
It is determined whether or not 48 has been reached.

In the case of this embodiment, the CPU 6 counts from the 0th clock time position to the 47th clock time position during one bar based on the rhythm information S15 sent from the tempo generator 33. If a positive result is obtained in SP78 (this means that the rhythm performance for one measure has ended and the next measure has started), the CPU 6
Goes to step SP79, resets the tempo count data TCNT by rewriting the value to 0, and then returns to step SP79.
At 80, the file-in flag data FILFG is logic "1"
It is determined whether or not.

If an affirmative result is obtained here (this means that the rhythm sound signal generation circuit (TG2) 29 is currently performing a rhythm play in a file-in pattern), the CPU 6 proceeds to step SP81 to execute the file-in. After resetting the value of the flag data FILFG to logic "0", in the next step SP82, the rhythm volume data temporary save data RHYVOL1
To rhythm volume data RHYVOL2,
The rhythm volume data RHYVOL2 is sent to the rhythm sound signal generation circuit (TG2) 29 as rhythm sound generation information S11.

At this time, the rhythm sound signal generation circuit (TG2) 29 changes from the state where the rhythm volume data RHYVOL2 was previously played at a volume corresponding to the rhythm volume data RHYVOL2 to the volume corresponding to the rhythm volume retained as the rhythm volume data temporary save data RHYVOL1. Perform a sounding operation that returns. Thus, the rhythm interrupt routine ends, and the CPU 6 returns from step SP83 to the main routine.

When the performance of the one-measure file-in pattern ends and the next measure starts, the rhythm sound signal generation circuit (TG
2) 29 returns to the state of generating the rhythm sound of the normal pattern.

On the other hand, if a negative result is obtained in step SP75 (this means that the rhythm is not in the rhythm playing state at the timing when the rhythm interrupt signal S16 is generated), the CPU 6 returns to the main routine from step SP83. .

If a negative result is obtained in step SP78 (this means that the measure to be played in the file-in pattern has not been completed yet), the CPU 6 jumps to step SP83 and returns to the main routine.

Further, if a negative result is obtained in step SP80 (this means that the current performance state is not a rhythm performance in a file-in pattern), the CPU 6 jumps to step SP83 and returns to the main routine.

(8) Operation and effect of the first embodiment In the above configuration, when assigning the start switch function to the i-th pad PAD (i) among the pads PAD1 to PAD4, the player must use the pad sign switch PADA and start. When the switch ST is turned on at the same time, an operation of hitting the i-th pad PAD (i) with a stick is performed.

At this time, the CPU 6 executes the pad switch event subroutine RT2 (fourth step) based on the pad switch signal S2.
By obtaining an affirmative result in steps SP4 and SP5 in FIG. 7, the current state is reversed in step SP7 or SP9 depending on whether the start switch function has been assigned to the pad PAD (i). Processing.

The processing of the CPU 6 is such that when the electronic musical instrument 1 is in the playing operation state, the start function can be arbitrarily performed by a relatively simple operation in which the player hits one of the pads PAD1 to PAD4 with a stick. Can be assigned to or released from pads.

Next, the ith pad PAD of the pads PAD1 to PAD4
To assign the file switch function to (i), the player turns on the pad sign switch PADA and the file switch FIL at the same time and turns on the pad PAD.
An operation of hitting (i) with a stake may be performed.

At this time, the CPU 6 executes the steps SP4-SP5-SP11-SP12 of the pad switch-on event subroutine RT2 (FIG. 4) in accordance with the state of the file switch function assignment pad number data FILREG so far. A process for inverting the file switch function assignment pad number data FILREG is executed in step SP13 or SP14.

Therefore, in this case as well, the performer can switch the performance by the file inverter as necessary during the performance by a simple operation.

Further, when the player wants to assign a desired rhythm sound source to the i-th pad PAD (i) of the pads PAD1 to PAD4 as necessary, the player performs a pad sign switch PADA.
The pad PAD (i) may be operated in a state where is turned on.

At this time, the CPU 6 executes the steps SP4-SP5-SP11-SP21 of the pad switch-on event subroutine RT2 (FIG. 4).
-Pad assigned sound source number data by the loop of SP22
Each time the pad PAD (i) is hit, TONE (i) can be incremented by “+1”, and thus the player simply hits the pad PAD (i) until the desired rhythm sound source is obtained. A desired rhythm sound source can be assigned by only a simple operation.

When a file-in pattern is inserted in the middle of a rhythm performance, the player may perform an operation to assign a file-in switch function to the rhythm sound source.

That is, after the player has hit the pad PAD (i) with the pad sign switch PADA and the file switch FIL turned on at the same time, the pad sign switch PADA may be turned off.

At this time, the CPU 6 firstly performs steps SP4-SP5-SP11 of the pad switch-on event subroutine RT2 (FIG. 4).
-The pad PA corresponding to the pad number data FILREG to which the file switch function is assigned by the loop of -SP12-SP14.
The pad number i of D (i) can be set, and following this state, the rhythm volume data RHYVOL2 (step SP4-SP31-SP32-SP33-SP34) or step SP4-SP31-SP32-SP33-SP35 is looped. This indicates the volume of the current rhythm sound) and the rhythm volume held in the rhythm volume data temporary save data RHYVOL1 can be exchanged with each other, thus making it easy to switch between the file-in pattern and the normal pattern Can be performed by

[2] Second Embodiment FIG. 10 shows a second embodiment of the present invention. In this case, the CPU 6 executes the processing of steps SP34X and SP35X instead of steps SP34 and SP35 of FIG. 4, as shown by attaching the same reference numerals to the parts corresponding to FIG.

That is, in the case of FIG. 10, when an affirmative result is obtained in step SP33, the CPU 6 proceeds to step SP34X to hold the rhythm volume data RHYVOL2 in the rhythm volume data temporary save data RHYVOL1 and to make the pad-specific touch data VOLREG (i). To the rhythm volume data RHYVOL2 and the rhythm volume data RHYVOL2
Is converted into conversion data R (RHYVOL2) and written into the conversion data register REG13 (FIG. 3), and then written into the rhythm selection register REG12 as rhythm selection data RHYSEL.

Here, the conversion data R (RHYVOL2) is based on the rhythm volume data RHYVOL2 based on the sound volume.
When the rhythm volume data RHYVOL2 is in the low band, the middle band, or the high band, the conversion data R (RHYVOL2) corresponding to the low band, the middle band, or the high band is divided into the high band.
As a result, a rhythm selection signal RHYSEL including the contents of selecting the 0th, 1st, and 2nd rhythms can be set.

In addition, the CPU 6 sends the rhythm volume data RHYVOL2 and the rhythm selection data RHYSEL to the rhythm sound signal generation circuit (TG2) 29 in step SP34X.

At this time, the rhythm sound signal generation circuit (TG2) 29 generates a rhythm sound having the rhythm selected based on the rhythm selection data RHYSEL at the volume of the rhythm volume data RHYVOL2.

When a negative result is obtained in step SP33, the CPU 6 shifts to step SP35X and stores the rhythm volume data temporary save data RHYVOL1 in the rhythm volume data RHYVOL1.
After returning to VOL2, the rhythm volume data RHYVOL2
And the rhythm selection data RHYSEL is sent to the rhythm sound signal generation circuit (TG2) 29.

Thus, the rhythm sound signal generating circuit (TG2) 29 produces the rhythm sound of the rhythm specified by the rhythm selection data RHYSEL at the volume specified by the rhythm volume data RHYVOL2.

According to the configuration of FIG. 10, the player performs the file switch function at step SP14 by hitting the pad PAD (i) with the pad sign switch PADA and the file switch FIL simultaneously turned on. After setting the pad number data FILREG and changing the tone and the tone before switching between the file-in pattern and the normal pattern, simply turn off the pad sign switch PADA. , A more lively effect can be provided.

[3] Third Embodiment FIGS. 11 to 13 show a third embodiment of the present invention.
In FIG. 11, in which parts corresponding to those in the figure are assigned the same reference numerals, after the initial setting in the subroutine RT1 in FIG.
Between the pad switch event subroutine RT2 and the pad sign switch event subroutine
Run RT1X.

In this embodiment, 32 rhythm sound sources are prepared.
32 rhythm sound sources are divided into four groups according to timbre, that is, 0th to 7th rhythm sound source groups, 8th to 15th rhythm sound source groups, 16th to 23rd rhythm sound source groups, and 24 to 31 rhythm sound source groups. A sound source of the same type of timbre is assigned to each rhythm sound source group.

As a method of dividing the rhythm sound source group, for example, a bass drum, a bongo, a conga, etc. are grouped into a plurality of musical instrument groups as a drum-type sound source, and a hi-hat cymbal, a top cymbal, a rim shot, etc. as a cymbal-type instrument. They are organized into one or more rhythm sound source groups.

PAT Door Sign Switch Event Subroutine RT
1X executes a processing program as shown in FIG. 12 and also executes a subroutine shown in FIG. 13 as a pad switch-on event subroutine RT2.

In FIG. 12, when the CPU 6 enters the pad sign switch ON event subroutine RT1X, it determines in step SP85 whether or not an on event has occurred in the pad sign switch PADA.
At 86, the sound source number 8 is added to the pad assigned sound source number data TONE (i) to be assigned to the i-th pad PAD (i), and new pad assigned sound source number data TONE is added.
(I) can be designated.

The processing in this step SP86 means that the content of the pad assigned sound source number data TONE (i) can be added by "+8" every time the player turns on the pad sign switch PADA. 7th, 8 ~
15th, 16th to 23rd, 24th to 31st rhythm sound sources 4
This indicates that sound source numbers in one sound source group can be specified in an intermittent manner.

The CPU 6 determines whether or not the pad assigned sound source number data TONE (i) obtained by adding "+8" in the next step SP87 has exceeded the maximum number of sound sources 32. If a positive result is obtained, the "+8" is obtained in step SP88. By subtracting “−32” from the added pad assigned sound source number data TONE (i), a new first rhythm sound source group (that is, 0th to 7th sound sources) can be newly designated.

On the other hand, if a negative result is obtained in step SP87, the CPU 6 jumps to step SP88 and proceeds to step SP89.
To return to the main routine.

Alternatively, if a negative result is obtained in step SP85, the process returns from step SP89 to the main routine without executing a process of adding "+8" to the pad assigned sound source number data TONE (i).

Next, the CPU 6 executes processing in the pad switch event subroutine RT2 of FIG. 13 which differs from the case of FIG. 4 in the following points.

That is, in FIG. 13 in which the same reference numerals are given to the parts corresponding to FIG. 4, the CPU 6 performs the steps SP4-SP5-SP11-SP21.
In order to realize the sound source selection switch function through the loop, the player performs a processing step for designating a desired sound source.

That is, the CPU 6 adds "+1" to the pad assigned sound source number data TONE (i) in step SP21, and sequentially obtains "+1" by sequentially executing the determinations in steps SP91, SP92, SP93 and SP94. It is determined whether or not the pad assigned sound source number data TONE (i) has sequentially reached 8, 16, 24, or 32.

This determination is based on the head number of each sound source group, that is, the head number 8 of the second group, the head number 16 of the third group, and the head number 2 of the fourth group.
4. It is determined whether or not the first group has reached the leading number 32 (that is, 0).

When an affirmative result is obtained in any one of these steps SP91, SP92, SP93, and SP94, the CPU 6 moves to steps SP95, SP96, SP97, and SP98, respectively, and proceeds to the first step.
By setting the head numbers 0, 8, 16, and 24 of the sound source groups of the group, the second group, the third group, and the fourth group, the sound source that the player wants to select from the sound sources of the head number of the sound source group is newly specified. Then, in step SP8, it is possible to sequentially generate sounds.

According to the configuration of FIGS. 11 to 13, an extremely large number of four pads PAD1 to PAD4 as performance operators, for example,
When selecting and assigning 32 sound sources, the sound source is divided into sound source groups in advance based on the tone colors of the sound sources, and the performer can search for the desired sound source for each sound source group. The task of searching for a desired sound source by the user is not so complicated.

After rewriting the file switch function assignment pad number data FILREG to the value i by the loop of SP12-SP14, the CPU 6 executes the processing of assigning the file switch function to the i-th pad PAD (i). Step
After moving to SP100, the pad-specific touch data VOLREG (i) of the i-th pad PAD (i) is written to the full involution data register REG11 of the register 25 (FIG. 3) as file involution data FILVOLREG.
8. Return to the main routine via SP2.

In this manner, the file switch function assignment pad number data FILREG and the file
When the performer turns off the pad sign switch PADA after setting the OLREG, the CPU 6 executes steps SP4-SP31-S.
Step S after executing the processing of the processing routine of P32-SP33
P34Y processing is performed.

The processing in step SP34Y is the same as step SP34 in FIG.
First, the rhythm volume data RHYVOL2 is replaced with the rhythm volume data temporary save data R
HYVOL1 is temporarily held, and the file-in volume data FILVOLREG set in the above-described SP100 is set in the rhythm volume data RHYVOL2, and then the rhythm volume data RHYVOL2 is stored in the rhythm sound signal generation circuit (TG

According to the configuration of FIG. 14, the file switch function
When assigning to the pad PAD (i) (step SP1
4) Almost at the same time, touch data VOLREG by pad
By registering (i) as file-involume data FILVOLREG in the file-involume data register REG11, a rhythm sound having a volume corresponding to more appropriate rhythm volume data can be generated.

[5] Other embodiments (1) In FIG. 4, FIG. 13, and FIG.
After executing the processing of the start subroutine in SP42, the pad assigned sound source number data T
Although the sound source of ONE (i) is sounded, and then the process returns to the main routine from step SP2, the sound source of ONE (i) may be returned to the main routine immediately from step SP42 without executing the sound generation process of step SP8.

(2) In the embodiment shown in FIGS. 11 to 13, the pad PA is operated while the pad sign switch PADA is turned on once.
Each time the player hits D (i), another rhythm sound source group is selected. However, the method of selecting the rhythm sound source group is not limited to this. Alternatively, another rhythm sound source group may be selected only when the on operation is performed two or more times within the range.

In this case, when the pad sign switch PADA is turned on once, the same rhythm sound source group as the previously selected rhythm sound source group is selected again, and in this state, the pad pad (PAD) is turned on while the pad sign switch PADA is turned on. i)
By operating, the rhythm sound source in the same rhythm sound source group can be selected.

(3) In the above embodiment, the case where the rhythm sound source group is specified based on the pad assigned sound source number data TONE (i) has been described.
