* For the address, size, and checksum, refer to “Examples of system exclusive messages
and calculating the checksum” (P. 206).
* Data whose size is greater than 128 bytes should be divided into packets of 128 bytes or
less and transmitted. Successive “Data Set 1” messages should have at least 20 ms of
time interval between them.
* This message is not received if the Rx.System Exclusive Switch parameter is OFF.
The only GS exclusive messages received by the MC-307 are Scale Tune settings (P. 116).
