Further, in this embodiment, automatic performance data for automatic rhythm performance is stored in a predetermined area of the data and working RAM 12.

A plurality of performance operators (4 as an example)
Individual) drum pads P1 to P4 are provided. The pad detection circuit 14 is composed of a sensor and a detection circuit corresponding to each of the pads P1 to P4, detects that the pad has been operated by a player's hand or a stick, and outputs on / off information of the pad. And touch information is given to the bus 13. The switch group 17 includes various switches and volumes for selecting, setting and controlling pitch, tone color, volume, pitch, effect, etc. provided on the keyboard and panel of the electronic musical instrument. The switch detection circuit 15

The display circuit 16 includes a display device provided on the panel portion of the electronic musical instrument, and is configured to perform various displays on the display device in accordance with the data given from the bus 13.

The tone generator circuit 18 is capable of generating different tone signals (eg, electronic percussion tone signals) on a plurality of tone generating channels. The process of assigning a musical tone to each musical tone generating channel (this is known as a key assigning process) is performed under the control of the CPU 10. Information indicating the musical tones assigned to each musical tone generation channel is transmitted via the bus 13 to the tone generator circuit 18
The tone generator circuit 18 generates a tone signal in each tone generation channel based on the above information. As is well known, the tone generation channels in the tone generator circuit 18 may be formed in a time division manner by using a common hardware circuit for each channel in a time division manner, or separate hardware circuits. May be formed in parallel. Any tone signal generation method may be used in the tone generator circuit 18. For example, a method (memory reading method) of sequentially reading the musical tone waveform sample value data stored in the waveform memory according to the address data that changes corresponding to the pitch of the musical tone to be generated,
Alternatively, a predetermined frequency modulation calculation is performed by using the address data as phase angle parameter data to obtain musical tone waveform sample value data (FM method), or a predetermined amplitude modulation calculation is performed by using the address data as phase angle parameter data. Any known method such as a method for obtaining musical tone waveform sample value data (AM method) may be used.

A digital tone signal generated from the tone generator circuit 18 is converted into an analog tone signal by a digital / analog converter 19 and spatially sounded via a sound system 20. The timer 21 generates a clock pulse of a predetermined cycle according to the performance tempo, and the timer clock pulse is added to the CPU 10 and acts as a timer interrupt signal. The clock frequency of the timer 21 is variably controlled according to the tempo setting data.

FIG. 2 shows the pads P1 to P1 in the panel section.
An example of arrangement of P4, various switches, and display DPY is shown. The display device DPY consists of a 2-digit 7-segment LED. In FIG. 2, some of the switches included in the switch group 17 are related to the automatic rhythm performance.
Explaining this, the tempo setting switch TEMP
O is an up / down switch and sets the tempo of the automatic rhythm. Style switch group ST
YLE is for selecting a style of automatic rhythm performance, and an arbitrary style number can be selected by operating a total of 10 keys of 1, 2, 3, ... 0. The style of automatic rhythm performance corresponds to rhythm types such as 8-beat rock, 16-beat rock, and bossa nova. Rhythm function selection switch group RHYTHM
FUNC. Consists of a switch for selecting the control function of the automatic rhythm performance. Start / stop switch S
/ S is for controlling the start / stop of the automatic rhythm performance. The intro switch INT is for instructing to play the intro pattern. The fill-in switch FIL is for instructing to play the fill-in pattern. The ending switch END is for instructing to play the ending pattern.

In the automatic performance data storage area of the RAM 12, a plurality of patterns (that is, normal pattern, intro pattern,
Stores performance data regarding fill-in patterns and ending patterns. Normally, the performance data of the normal pattern is repeatedly read, but when the intro is instructed, the performance data of the intro pattern is read,
When fill-in is instructed, the performance data of the fill-in pattern is read out, and when ending is instructed, the performance data of the ending pattern is read out.

An arbitrary musical sound (percussion instrument sound) generation instruction function can be assigned to each of the pads P1 to P4, and at the same time, the above-mentioned control function (ie start / start) in the automatic performance. Stop control function, intro instruction function, fill-in instruction function, ending instruction function) can be assigned. The assign switch ASSIGN is provided for each pad P1.
To P4 are switches used when assigning desired functions to P4. For these control functions, as described above, the dedicated switches S / S, INT, FIL, E
ND is provided, but if similar control functions can be arbitrarily assigned to arbitrary pads P1 to P4, even if the player holds the stick in his hand and plays the pad, these control functions can be selected.・ It is convenient because you can easily give instructions.

The automatic performance execution control for reading the automatic performance data from the automatic performance data storage area of the RAM 12 and causing the tone generator circuit 18 to generate the automatic performance sound based on the read automatic performance data is executed by a microcomputer including the CPU 10 and the like. To be done. In addition, each pad P1
The processing for assigning a desired function to P4 is also executed by the microcomputer based on the output of the assign switch ASSIGN. Then, when any of the pads P1 to P4 is operated, the processing of supplying the operation information corresponding to the function assigned to the operated pad is also executed by the microcomputer.

When a control function is assigned to each of the pads P1 to P4, the assigned control function can be confirmed by generating a predetermined confirmation sound corresponding to the assigned control function. This confirmation sound generation control is executed by the microcomputer, and the confirmation sound is generated by the sound source circuit 18 in response to this, and the sound system 2
It is pronounced from 0. When a control function is assigned to each of the pads P1 to P4, the assigned control function can be confirmed by displaying a display corresponding to the assigned control function. This confirmation display control is executed by the microcomputer, and accordingly, the display D
A predetermined display is made in PY. An example of the confirmation display on the display device DPY is as shown in FIG. (A)
Is a display example showing the start / stop control function, (b) is a display example showing the intro instruction function, (c) is a display example showing the fill-in instruction function, and (d) is a display example showing the ending instruction function. With 2-digit 7-segment LED,
They are displayed as "St", "In", "FL", and "En", respectively, to suggest their functions.

Next, an example of the processing executed by the microcomputer will be described with reference to the flowchart. FIG. 4 shows an example of the main routine. First, a predetermined initialization process is performed, and then the "switch process", "pad process", and "other process" routines are repeated.
In the "switch processing", each switch and operator in the switch group 17 are scanned to detect their on / off states and operation amounts, and when a change event occurs, processing corresponding to the event is performed. An example of this "switching process" is shown in FIG. In the "pad processing", the pad P1
The sensors P4 to P4 are scanned to detect their on / off states, and when a change event occurs, a process corresponding to the event is performed. An example of this "pad processing" is shown in FIG. In "other processing", various other processings are performed. During execution of the main routine, interrupts are periodically applied by the clock pulse of the timer 21. In that case, the timer interrupt process of FIG. 7 is performed.

First, the outline of the process of assigning desired functions to the desired pads P1 to P4 will be described. As an example, there are 60 tone generation instruction functions (that is, electronic percussion instrument timbres) that can be assigned to pads, and each tone generation instruction function (that is, electronic percussion instrument timbres) is distinguished by a function number from 0 to 59. For example, the function number 0 corresponds to the bass drum, 1 is the snare drum, 2 is the rim shot, 3 is the high tom, 4 is the rotom, and so on, which corresponds to the percussion instrument tone color. Also, as an example, there are four automatic performance control functions that can be assigned to the pads, and each control function is distinguished by a function number of 60 to 63.
For example, the function number 60 is the start / stop control function,
61 is an intro instruction function, 62 is a fill-in instruction function,
Reference numeral 63 corresponds to the ending instruction function.

When the desired pad (one of P1 to P4) is hit while the assign switch ASSIGN is turned on, the "assignment confirmation mode" is set by the first stroke of the pad. In this "assignment confirmation mode", a confirmation sound corresponding to the tone generation instruction function (that is, electronic percussion instrument tone color) or the automatic performance control function currently assigned to the pad is generated and a confirmation display is made. Next, when the same pad is further hit while continuing to turn on the assign switch ASSIGN, the "assignment mode" in which another function is assigned to the pad is set. That is, with the function number corresponding to the function that has been assigned to the pad as the initial value, the further 1 of the pad is set.
Each time the stroke is made, the function number is incremented by 1, and the function number assigned to the pad is updated. In this way, the function corresponding to the updated function number is newly assigned to the pad. Assignment registers TONE1 to TONE4 are provided corresponding to the pads P1 to P4, and store function numbers corresponding to the functions assigned to the pads P1 to P4. The updating of the above function number is performed on the storage contents of the allocation registers TONE1 to TONE4.

Next, an example of the switch process will be described with reference to FIG. First, in step 30, it is checked whether the assign switch ASSIGN is turned on. If it is turned on, the process goes to step 31, and the first flags FRIST1 to FST1 corresponding to the pads P1 to P4 are
Set FRIST4 to "1". When the first flags FRIST1 to FRIST4 are "1", it is indicated that the pad to be hit is the first hit. That is, it is instructed that the mode is the above-mentioned “allocation confirmation mode”. Next, at step 32, the assign flag ASSIGF is set to "1" to indicate that the assign switch ASSIGN is turned on.

In the next step 33, it is checked whether the assign switch ASSIGN is turned off. If it is off, go to step 34 and assign flag A
Reset SSIGF to “0” and assign switch A
Indicates that SSIGN has been turned off. Next, step 3
5, the RUN flag indicating that the automatic rhythm performance is being executed is reset to "0". This is because when the assign switch ASSIGN is turned on as will be described later, the RUN flag indicating that the automatic rhythm performance is being executed is set to "1" in order to generate the above-mentioned confirmation sound.
This is because when the SIGN is off, it is reset to erase the pronunciation of the confirmation sound. After that, go to step 36, and perform other switch processing (for example, tempo setting switch TE
Tempo setting / change processing based on MPO operation, style selection processing based on operation of style switch group STYLE, rhythm function selection switch group RHYTHM FUN
C. Automatic rhythm movement change control processing based on the operation of
To execute.

Next, an example of pad processing will be described with reference to FIG. First, in step 40, it is checked whether any of the pad switches P1 to P4 has been turned on. If it is turned on, the process goes to step 41, and the numbers of the turned-on pads P1 to P4 are set in the register i.
In the next step 42, it is checked whether the assign flag ASSIGF is set to "1". When performing the allocation process, as described above, the assign flag ASSI
Since GF is set to "1", this step 42 branches YES to step 43. Hereinafter, the description will proceed assuming that the assign flag ASSIGF is set to "1".

At step 43, the first flag FRIS corresponding to the pad number i related to the current on event is set.
It is checked whether Ti is set to "1", that is, "allocation confirmation mode". If YES, that is, in the "allocation confirmation mode", go to step 44, reset the flag FRISTi to "0", and then go to step 45 to find out the contents of the allocation register TONEi corresponding to the pad number i related to the on event this time. It is checked whether the function number is 0 to 59. When the musical tone generation instruction function (that is, percussion instrument sound) is assigned to the pad related to the current on-event, the function number 0
YES in step 45, as it corresponds to any of ~ 59
And the processing of steps 46 and 47 is performed.

In step 46, the allocation register TO
According to the function number stored in the NEi, predetermined operation information (a tone generation instruction function corresponding to the function number, that is, information indicating that an operation for instructing to generate a percussion instrument sound is performed) is generated. , Instruct to generate the percussion sound assigned to the pad related to the current on event. In response to this, a process of assigning an instructed percussion instrument sound to an appropriate channel is performed, and the percussion instrument sound is generated in the assigned channel of the tone generator circuit 18. As a result, the percussion instrument sound assigned to the pad relating to the current on-event can be auditorily confirmed. Step 47
Then, according to the function number stored in the allocation register TONEi, a predetermined display is performed on the display device DPY.
As a result, the percussion instrument sound assigned to the pad related to the current on event can be visually confirmed. It should be noted that this confirmation display is performed only for a predetermined time.

On the other hand, if the automatic performance control function is assigned to the pad related to the on event this time, it corresponds to any one of the function numbers 60 to 63, so step 4
5 branches to NO and performs the processing of steps 48-52. In steps 48 to 52, a process of generating a predetermined confirmation sound corresponding to the automatic performance control function assigned to the pad related to the current on-event, and a process of performing a predetermined display corresponding to the control function. Do. First, in step 48, the allocation register T is selected from among various patterns in the currently selected automatic rhythm style.
A predetermined one pattern is selected according to the function number stored in ONEi, an address pointer is set from the automatic performance data storage area of the RAM 12 to the start address of the storage area of this pattern, Read the data in the header section. This is a process for producing a performance sound corresponding to a predetermined pattern as a confirmation sound. An example of the relationship between each control function and the pattern selected to be generated as the confirmation sound is shown. When the function number of the register TONEi indicates the start / stop control function, the normal pattern is selected and the intro instruction function is selected. Indicates the intro pattern, the fill-in instruction function indicates the fill-in pattern, and the ending instruction function indicates the ending pattern. Next, at step 49, a state is set in which the automatic performance can be executed according to the read header data. The header data includes, for example, data indicating the number of beats per bar.

Here, an example of storing performance data will be described. In the automatic performance data storage area of the RAM 12, each pattern has header data stored at the beginning, and subsequently, each musical tone to be generated. The timing data indicating the sounding timing in the measure, event data consisting of the note number corresponding to the type of percussion instrument sound and velocity data indicating the strength of the sound, and the pattern end data indicating the end of the pattern, in the order of sounding. I remember. In this example, the timing data indicates the time from the beginning of the bar to the sound generation timing in reference time units obtained by dividing one bar into 96.
If one pattern consists of multiple measures,
The bar line data is stored next to the last data of one bar. This means that there are no more events in the bar and the bar line will come next. After this bar line data, for each musical sound to be generated in the next bar,
Data below the above-mentioned timing data is similarly stored. The address pointer sequentially designates the addresses of the data from the header data of each pattern to the pattern end data, and the data of the pattern is sequentially read and reproduced by such address designation. ..

At the next step 50, the address pointer is advanced to read the first timing data stored at the next address of the header portion, and the read timing data is stored in the timing data register TIME. In this way, the preparation for reading the event data of the pattern is completed. Then, in the next step 51, the running flag RUN is set to "1" to indicate that the automatic performance is running, and the clock register CLOCK indicating the current progress position in the bar is reset to "0". In the next step 52, a predetermined display is performed on the display DPY according to the function number stored in the allocation register TONEi. As a result, the control function assigned to the pad related to the current on event can be visually confirmed. This display example is as described above with reference to FIG. It should be noted that this confirmation display is also performed only during a predetermined time. Otherwise, for example,
The style number of the currently selected automatic rhythm is displayed on the display DPY. After that, the pad processing is terminated and the process returns to the main routine.

The process for producing the performance sound corresponding to the pattern selected and set in steps 48 to 51 is shown in FIG.
It is executed by the timer interrupt processing of. During execution of the main routine of FIG. 4, every time a timer 21 gives a timer interrupt signal to the CPU 10, the timer interrupt process shown in FIG. 7 is performed. In this embodiment, the timer interrupt signal is generated at every timing when one bar is divided into 96. That is, for example, in the case of a quarter quarter beat, 24 timer interrupt signals (24 tempo clocks) correspond to the note length of a quarter note. In the timer interrupt process of FIG. 7, first, it is checked whether or not the traveling flag RUN is "1" (step 60). When the result of step 60 is NO, it means that the automatic performance has not started, and therefore the routine returns to the main routine without performing other processing.

When the automatic performance is running, the result of step 60 is YES, and in this case, the next step 6
At 1, it is checked whether the value of the clock register CLOCK and the value of the timing register TIME match. Here, the timing register TIME stores the timing data indicating the sounding timing within one bar of the sound to be sounded next, and this timing data corresponds to the reading of the pattern data as described above. Stored in. The clock register CLOCK counts the current performance progress position within one bar in the above-mentioned reference time unit. In this embodiment, the clock register CL
OCK is, for example, 0 to 95 in the case of a quarter meter
Values are taken from 0 to 71 in the case of three quarters. Therefore, in this step 61, it is checked whether or not the current proceeding position in the bar matches the sounding timing indicated by the timing data of the pattern currently being played.

When the result of step 61 is YES,
Since the next tone generation timing has arrived, the process proceeds to step 62 in order to generate a musical tone. Step 62
At, the event data is read according to the address pointer and output to the tone generator circuit 12. Sound source circuit 12
Then, a percussion instrument sound signal is generated in accordance with given event data, that is, note number and velocity data. In the next step 63, the address pointer is advanced to read the next data (that is, any of timing data, bar line data and pattern end data). In step 64, it is checked whether the read data is pattern end data. When the read data is not pattern end data, it is further checked whether it is bar line data (step 6).
5). NO, that is, when it is not bar line data,
The read data is the timing data. In this case, the value of the timing data is stored in the timing register TIME (step 66).

Next, in step 67, it is checked whether or not the value of the clock register CLOCK and the value of the clock maximum value register MAX match. Here, the clock maximum value register MAX stores the clock maximum value for one bar in the above-mentioned reference time unit. In this embodiment, the maximum clock value in the case of quadrant is 95
The maximum clock value in the case of three-quarters beat is 71. Therefore, in this step 67, it is checked whether or not the current automatic performance progress position has reached the end of one bar. N
If it is O, go to step 68, and clock register C
The value of LOCK is incremented by 1, and then the process returns to the main routine.

Next, when a timer interrupt occurs, the same processing as described above is repeated. Then, by the processing of step 68, the value of the clock register CLOCK, that is, the current advance position within the bar is incremented by 1 for each timer interrupt processing. Eventually, if CLOCK = TIME is satisfied in step 61, it means that the next sounding timing has arrived, and thus the percussion sound is generated by the process of step 62 as described above. Thus
When it reaches the end of one bar, it automatically pronounces according to the pattern, and step 67 branches to YES.
In step 69, the clock register CLOCK is reset to "0". Next, in step 70, it is checked whether the pattern end flag PEND is "1". If it is not the pattern end, PEND
Is "0", the process branches to NO to go to step 71.
In step 71, the next timing data, that is, the timing data related to the first event of the next bar, is read out, and the value of the read timing data is stored in the timing register TIME. Then, the process returns to the main routine. Eventually, when the end of the pattern is reached, the pattern end data is read out, and in step 64, YE
Branch to S and go to step 72. In step 72, the pattern end flag PEND is set to "1". As a result, the determination in step 70 is YES and the process proceeds to step 73. In step 73, the traveling flag RUN is reset to "0". As a result, in the next timer interrupt process, the process branches to NO in step 60,
Immediately returns to the main routine. Therefore, the generation of the automatic performance sound ends.

The timer interrupt process of FIG.
Only the portion related to the sounding of the confirmation sound according to the present invention is schematically shown. That is, when the pattern end arrives, the automatic performance is stopped by the processing of step 73. This is because only one pattern of performance sound is used as the confirmation sound corresponding to the control function assigned to the pad. This is because I pronounce it. If it is a normal automatic performance, for example, if it is a normal pattern,
When the pattern end arrives, the control is performed so that the performance is returned to the beginning of the pattern and the performance is repeated. However, when the confirmation sound is produced, only one pattern is generated even if it is a normal pattern. As mentioned above,
In the "assignment confirmation mode" (when step 43 of FIG. 6 branches to YES), a performance sound for confirming the control function assigned to the pad can be generated.

Next, the "assignment mode" will be described. When the same pad is tapped twice or more while the assign switch ASSIGN is turned on, the "assignment mode" is set. That is, step 4 in FIG. 6 is performed in response to the first hit.
In step 4, the first flag FRISTi corresponding to the pad number i related to the current on-event is reset to "0", so in the second and subsequent hits, step 4
The determination FRISTi = "1" of 3 branches to NO and goes to step 53. This results in the "assignment mode".
In step 53, it is checked whether the content of the allocation register TONEi corresponding to the pad number i related to the current on event has reached the maximum value 63. If NO, go to step 54 and increment the content of the register TONEi by 1. If yes, go to step 55
The contents of the register TONEi are cleared to the initial value 0. As a result, the function number stored in the register TONEi is updated, and the function assigned to the pad relating to the current on event is changed to the function corresponding to the updated function number. Therefore, each time the pad is pressed once, the assigned function number increases in sequence, and when it reaches the maximum value 63, it returns to 0 and becomes 0.
The increase from 1 to 63 is repeated. Then, the process goes to step 45 and the same process as described above is performed. Therefore, even when a desired control function is assigned to a desired pad, the assigned control function can be dealt with by the process of passing through the route of steps 53 to 55, 45, 48 to 52 and by the timer interrupt process described above. A confirmation display and confirmation sound can be generated.

If the assign switch ASSIGN is not turned on and the pads P1 to P4 are struck alone, step 42 of FIG. 6 branches to NO and step 5
By the processes of 6 to 58, the process of supplying the operation information corresponding to the function assigned to the pad related to the on event of this time is performed. That is, in step 56, it is checked whether the content of the allocation register TONEi corresponding to the pad number i related to the current on event is any of the function numbers 0 to 59. When the musical tone generation instruction function (that is, percussion instrument sound) is assigned to the pad related to the on event this time, it corresponds to any one of the function numbers 0 to 59, so step 56 branches to YES, and the process of step 57. Do. In step 57, the allocation register T
According to the function number stored in ONEi, predetermined operation information (a tone generation instruction function corresponding to the function number, that is, information indicating that an operation for instructing to generate a percussion instrument sound is performed) is generated. , Instruct to generate the percussion sound assigned to the pad related to the current on event.
In response to this, a process of assigning an instructed percussion instrument sound to an appropriate channel is performed, and the percussion instrument sound is generated in the assigned channel of the tone generator circuit 18.

On the other hand, if the automatic performance control function is assigned to the pad related to the on event this time, it corresponds to any of the function numbers 60 to 63, so step 5
6 branches to NO and performs the process of step 58. At step 58, predetermined operation information (information indicating that the control function is selected) corresponding to the automatic performance control function assigned to the pad related to the current on-event.
To occur. Automatic performance control processing is performed according to the operation information corresponding to this control function. That is, the automatic performance control unit is instructed to start or stop the automatic rhythm performance, perform the intro performance, the fill-in performance, or the ending performance according to the control function.

In the above embodiment, the performance sound according to the predetermined performance pattern is generated as the confirmation sound of the control function, but the sound is not limited to this and may be another sound. Further, in the above embodiment,
The confirmation display disappears after a predetermined time, but it may be appropriately changed, for example, it is held until the next allocation operation is made, or it is held until the assign switch is released. Further, the content of the confirmation display is not limited to letters such as alphabets and may be numbers or the like, and the dedicated switches S / S, INT, F corresponding to the assigned functions.
A lamp (if provided) corresponding to IL or END may be turned on. The performance operator is not limited to the drum pad, and may be any operator such as a key on the keyboard or an appropriate tablet switch.

In the above embodiment, when a desired function is assigned to a pad, the number of the assigned function is sequentially changed in the + direction by repeatedly pressing the pad. However, the number of the assigned function is not limited to this. May be sequentially changed in the-direction. Further, not limited to this, by using a dedicated switch S / S, INT, FIL, END corresponding to the control function, a dedicated percussion instrument tone color selection switch, or the like, a desired control function or musical tone generation instruction function is selected. May be assigned to the pad. Further, the control function that can be assigned to the performance operator is not limited to the above-mentioned one, and may be any function. Further, in the above embodiment, the automatic rhythm performance has been described, but the present invention is not limited to the automatic rhythm performance, but can be applied to any other automatic performance apparatus such as an automatic accompaniment apparatus and a sequencer. Further, it goes without saying that the present invention can be applied to an automatic performance device module having no musical tone generating function or a device operated by an automatic performance software program.

As described above, according to the present invention, when an automatic performance control function is assigned to a performance operator, the assigned control is generated by generating a predetermined confirmation sound corresponding to the assigned control function. Since the function can be confirmed auditorily and the assigned control function can be visually confirmed, the player can actually perform an automatic performance to operate the performance. The control function assigned to the performance operator can be confirmed without operating the child, which is simple and can be confirmed during the assignment process, so the confirmation can be performed immediately. It also has the excellent effect.
