Then, the outputs of the switches 20L, 20U, 20D, 20R, 21U, 21D, 22 are sequentially scanned. Then, the on event of each of the switches 41, 40 and 20L to 20R, 21U, 21D, 22 is detected based on the scan result. Then, the following respective processes are performed according to the type of the switch in which the on event is detected.

(Iii-1) Tremolo switch 41 When the on event of the tremolo switch 41 is detected, the CP
The processing of U11 proceeds to the subroutine SBR1 shown in FIG. 6, and then proceeds to step Sa1 to invert the tremolo operation flag TR. In this case, when the step Sa1 is executed for the first time after the completion of the initialization process S0, the tremolo operation flag TR that has been cleared is reversed, so
The contents of TR change from "0" to "1". Then step Sa2
In, it is determined whether the tremolo operation flag TR is "1". If it is "1", steps Sa3 to Sa7 are executed to perform the tremolo processing.

On the other hand, if the result of the determination in step Sd1 is “NO”, the process proceeds to step Sd21, and if the result of the determination is “YES”, step Sd21.

When it is repeatedly turned on twice, three times ..., the value of the same parameter PTSD is "2", "3".
It will increase sequentially. Further, when the tremolo depth display is being performed, the value of the player tremolo speed parameter PTDP is successively increased each time the data switch 21U is turned on.

On the other hand, if the result of the determination in step Sd21 is “NO”, the process proceeds to step Sd22, the on event process of the data switch 22U is performed for other parameters, and then the process returns to the main routine.

Even in the above process, the maximum values of the parameters PTSP and PTDP are determined, and if these parameters PTSP and PTDP reach the maximum values by the operation of the data switch 21U, even if the switch 21U is further operated thereafter. , These parameters are prevented from increasing.

(Iii-7) Data switch 21D When the ON event of the data switch 21D is detected, the CPU 11 proceeds to the subroutine SBR6 (not shown). The process of this subroutine SBR6 is the same as the above-mentioned subroutine.

In this case, the process proceeds to step Se7 via steps Se1, Se3, Se4, and since the determination result of this step Se7 is "NO" (see step Se8), the process proceeds to step Se10. In step Se10, the vibrato depth display flag VDPF is set to "0" and the vibrato delay display flag VDLF is set to "1". Next, in step Se11, the above-mentioned vibrato delay display is performed again. That is, the vibrato delay parameter PVDL can be set again. Next, when the switch 20U is turned on again, the vibrato speed display is performed, and thereafter, every time the switch 20U is turned on, the vibrato depth display, the vibrato delay display, the vibrato speed display, ... Are repeated.

On the other hand, if "NO" is determined in the above-mentioned step Se1, the process proceeds to step Se21, and it is determined whether or not the tremolo flag TF is "1". The judgment in step Se21 is "NO"
In the case of, the process proceeds to step Se22, the process of setting other parameters is performed, and then the process returns to the main routine. This step
