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.
