Selecting Sounds on a GS Sound Module (Sending Program Change/Bank Select Messages)

Program Change/Bank Select messages are used for changing Tones for an ordinary instrument Part, and for changing Drum Sets for the Drum Part (GS: ch. 10).

Changing Sounds in a GS Sound Module

To change Tones in a GS module, you need to send the Bank Select message (consists of the values for Controller Numbers [CC] 00 and 32) together with the Program Number.

The value of Controller Number 00 (MSB) and that of Controller Number 32 (LSB) work together as a pair to specify a Bank. The Program Number that comes immediately after completes the switch to the desired sound.

On the PC-70, these three messages are always sent as one set:

Value of Controller Number 00 (MSB)

Value of Controller Number 32 (LSB)

Program Number xx

*You can conveniently refer to the GS/GM sound group list printed on the upper-right part of the PC-70’s panel when specifying a Program Number.
