When the power switch 28 is closed by the operation of the power operator 15, the power from the power circuit 29 is supplied to each circuit 21-26 via the switch 28, and the circuits 21-26 start operating. As a result, the CPU 26b starts executing the program from step 30 in FIG. 4, and determines in step 31 whether or not the play mode switch in the mode switch circuit 23 corresponding to the play mode operator 13 is on. To do. If the play mode switch is not on, it is determined as "NO" in the same step 31, and after the processing of step 32,
By executing the play routine and the assignment routine consisting of 4, the generation of percussion instrument sounds by the pad operators 11a to 11d and the assignment of percussion instrument sounds to the operators 11a to 11d are controlled.
If the play mode switch is turned on, it is determined to be "YES" in step 31, and the confirmation routine including steps 41 to 47 is executed, so that all kinds of percussion instruments that can be sounded by the electronic musical instrument are performed. Sound generation is controlled.

First, this confirmation routine will be described. In this confirmation routine, in step 41, the address data AD
After R is set to the initial value “0”, it is determined in step 42 whether or not there is an on event for any pad switch in the pad switch circuit 21. In this case, if none of the pad operators 11a to 11d is operated, the determination in step 42 continues to be "NO" and the program does not proceed from step 42. On the other hand, in this state, the pad operator
When any of 11a to 11d is operated, it is determined as "YES" in step 42, and the address data ADR is determined in step 43.

After the process of step 45, the address data ADR is updated by adding "1" to the address data ADR in step 46, and the address data ADR is changed from "15" by the comparison judgment process of ADR> 15 in step 47. The circulation process consisting of steps 42 to 47 is executed until it becomes larger.
Thus, for each operation of one of the pad operators 11a to 11d, all tone data TNDT stored in the tone data table 26d, that is, tone data representing a percussion note name that can be produced by the electronic musical instrument. The TNDT is sequentially read, the lamp corresponding to the data TNDT is turned on, and the percussion instrument sound is sequentially produced. Then, all tone data TNDT is read out and the address data ADR is "16".
If so, it is determined to be "YES" in step 47, the address data ADR is initialized to "0" again in step 41, and the circulation process of steps 42 to 47 is executed. By executing the confirmation routine consisting of steps 41 to 47, all the percussion instrument sounds that can be produced by the electronic musical instrument are audibly and visually confirmed according to the operation of any one of the pad operators 11a to 11d. It

Next, when the power operator 15 is operated as described above,
If the play mode control 13 is not operated, step

If the allocation mode switch in the above is in the off state, the program proceeds to step 52 based on the judgment of “NO” in step 51, that is, there is no on event related to the allocation mode switch, and in step 52, the pad switch circuit.
It is determined whether or not any switch in 21 is turned on. In this case, if none of the pad operators 11a to 11d is operated and the on event of the pad switch is detected, based on the determination of "NO" in step 52,
The circulation process including steps 51 and 52 continues to be executed.

On the other hand, when any of the pad operators 11a to 11d is operated, it is determined in step 52 that "YES", that is, an on event related to the pad switch is present, and the operated pad operators 11a to 11d are operated in step 53. Data to represent (1
4) is set as the pad data PAD, and step 54

The tone signal generating circuit 25 forms a percussion instrument tone signal corresponding to the supplied assigned tone data ASTN (PAD) and outputs the signal to the speaker 17 via the amplifier 25a. After the processing of the step 54, the program is returned to the step 51, and thereafter, the circulation processing including the steps 51 to 54 is continuously executed.

As a result, the percussion instrument sound assigned to the pad operators 11a to 11d operated in response to the operation of the pad operators 11a to 11d is generated. The assigned percussion instrument sound is either a standard setting by the process of step 32 (FIG. 4), or is assigned to each of the pad operators 11a to 11d by executing an assignment routine described later.

Further, in this state, when the allocation mode operator 14 is operated, the CPU 26b, which is executing the circulation process including steps 51 to 54, determines in step 51 that there is an ON event for the allocation mode switch, that is, “YES”. Then, by the processing of step 55, the program is executed in step 34 (Fig. 4).

As shown in detail in FIG. 6, such an allocation routine is started in step 60, and the mode switch circuit 23 is operated when the play mode operator 13 is not operated.
If the allocation mode switch in the table is in the off state, the program proceeds to step 62 based on the judgment of “NO” in step 61, that is, there is no on event related to the play mode switch, and in step 62, the pad switch circuit.
It is determined whether or not any switch in 21 is turned on. In this case, if none of the pad operators 11a to 11d is operated and the ON event of the pad switch is not detected, based on the determination of “NO” in step 62,
The circulation process including steps 61 and 62 continues to be executed.

On the other hand, when any of the pad operators 11a to 11d is operated, it is determined in step 62 that "YES", that is, an on event related to the pad switch is present, and the operated pad operators 11a to 11d are operated in step 63. Data to represent (1
4) is set as the pad data PAD, and it is determined in step 64 whether or not any instrument selection switch in the instrument selection switch circuit 22 is on. In such cases,
If any operator of the musical instrument selection operator group 12 is being operated and the musical instrument selection switch corresponding to the operator is on, it is determined as "YES" in step 64, and step 65
The tone data TNDT corresponding to the turned-on musical instrument selection switch is read from the tone data table 26d and assigned tone data AST specified by the pad data PAD.
Set as N (PAD). As a result, percussion instrument sounds that can be produced by the electronic musical instrument are assigned to the operated pad operators 11a to 11d.

After the processing of step 65, the assigned tone data ASTN (PAD) set in steps 66 and 67 is output to the lamp control circuit 24 and the tone signal generation circuit 25. The lamp control circuit 24 supplies the assigned tone data ASTN (PA
Based on D), the lamp corresponding to the same data ASTN (PAD) in the lamp group 16 is controlled to be lit for the duration of the percussion instrument sound, and the tone signal generation circuit 25 supplies the assigned tone data
Since a percussion instrument sound signal corresponding to ASTN (PAD) is formed and the signal is output to the speaker 17 via the amplifier 25a, the percussion instrument assigned to the operated pad operators 11a to 11d is visually and audibly. Will be confirmed.

On the other hand, if it is determined in step 64 that “NO”, that is, none of the musical instrument selection switches are on, the percussion instrument sound allocation processing in step 65 is not executed,
The pad operator 1 operated by the processing of steps 66 and 67
A lamp corresponding to the percussion instrument sound previously assigned to 1a to 11d is turned on in response to the operation, and the percussion instrument sound is emitted. After the processing of the step 67, the program is returned to the step 61, and thereafter, the circulation processing of the above-mentioned steps 61 to 67 is continuously executed.

As a result, in the state in which the musical instrument selection operator corresponding to the percussion instrument sound to be assigned in the musical instrument selection operator group 12 is operated,
By sequentially operating the pad operators 11a to 11d, desired percussion instrument sounds can be assigned to the pad operators 11a to 11d.

In addition, when the play mode operator 13 is operated in such a state, the CPU 26b, which is executing the circulation process including the steps 61 to 67, determines “YES” in step 61, that is, there is an on event related to the play mode switch. Then, the process of step 68 advances the program to the play mode routine (step 33 of FIG. 4) including steps 50 to 55.
