The initial value of each value is 0, and the CPU 102 resets each value to 0 when the performance data is read from the floppy disk (FIG. 15: S1204). Further, each value does not deviate from the range of -5 to +5 by the processing according to the occurrence of the modulation switch event (volume switch event, tempo switch event). After updating the value of Tune in this way, the modulation switch event process ends.

Then, when both the sound generation start processing and the lighting start processing are completed, the timer interrupt 1 is completed.

FIG. 27 shows the TIM set in timer interrupt 1
A process of decrementing the values of ER1 and TIMER2 at a predetermined cycle to turn off the sound and turn off the light 208 (timer interrupt 2) is shown. When the timer interrupt 2 is started, the CPU 201 first determines the state of the NoteOn flag, that is, whether or not the child device 200 is sounding (S2221). Here, if it is determined that the sound is being generated (S2221; true), then TIME

26; false), or after decrementing TIMER2 (S2228) or after performing the light-off process (S2229, S2230), terminates the timer interrupt 2. Although details are omitted in the above description,
The sound source 204 of the child device 200 according to the present embodiment starts generating a tone signal based on the tone color data stored in the RAM 203 in response to the occurrence of the above-described note-on event, and generates the tone signal in response to the occurrence of the note-off event. This is controlled by the CPU 201 so as to mute the tone signal being played. The light 208 is controlled by the CPU 201 so as to emit light in response to the light-on event and to turn off in response to the light-off event.

When the floppy disk is inserted into D130 and the tone control data is transferred to RAM 104 of master unit 100, assignment data (tone data, threshold data) corresponding to the tone control data is transmitted to each slave unit 200i and assigned. Therefore, the initial setting can be easily performed based on the tone control data recorded on the floppy disk. Slave unit 200i is inserted into each slave unit insertion hole 111j of base unit 100.
, The connector 112j can be connected to the connector 221i. The parent device 100 checks whether or not the connector 221i is normally connected to the connector 112j. Since the assignment is performed, the player places the child device 200i in the master device 1
