Note 5: If a Bank Select MSB value of 01H~7EH (SFX voice, or unused MSB) is received and the tone generator
does not have a voice corresponding to the last received LSB and Program Change, the tone generator will
produce no sound for that channel regardless of subsequent Key On messages.
(Commentary) Users employing the XG format to generate music data should note the following general
points.
●
The discussion and examples provided above are intended to clarify operating specifications relevant to tone-gen-
erator manufacture. During general operation the MSB, LSB, and Program Change information should always be
sent together (as under the MIDI standard).
●
For melody-voice play: If the channel cannot play from the bank selected by the last LSB specification, it will
revert to the most recent playable LSB specifications.
●
For rhythm-voice play: If the channel cannot play the kit selected by the last received Program Number, it will
revert to the most recent playable Program Number.
