AH okay… I captured the data from an editor. So there’s two messages sent to change the bank/program
00010830 16 — B0 00 00 1 — CC: Bank MSB
00010830 16 — C0 11 — 1 — PC: Percussive Organ
B0 00 (xx) is a CC control, that’s easy. 0-7 selects Bank A-H
C0 (xx) is a Program Change message? I’ve never seen this before. Hence my complete and utter confusion about this.
