So, CC 114 definitely starts song playback, yes? And is it value 0 or 127 (standard MIDI is 0 = off 127 = on) and further, on other commands that are a single command, IE no variables like tempo, volume bank and song etc) why do you have noted a value field of 0-127? Surely it should be just on or off?
Curious is all…oh and btw, cc114 on ch 16 at either 0 or 127 does not work (MM to BB) - ch 1 in factory mode does work…I recall reading somewhere there is a bug in the firmware that only allows MM to use channel 1???
