• cc0 61 is used by the N series (NS5R, NX5R) to select rDrm.

Initialization

Initialization happens when power turns on, when "GM System On" is received, and when "Set to GM" is executed (SysEx unknown). cc0 for channel 10 is set to 62, while all other 15 channels have cc0 set to 56.

Extended Multi Setup SysEx

Byte at index 0 (1st byte) sets program number (099 for Bank A, 0127 for Bank G melodic, 128~135 for Bank G drums). Bit 6 and bit 7 on byte at index 10 (11th byte) defines if the voice uses Bank A (0x00??????) or Bank G (0x01??????).

Progress

• Check if the drum kit ID to PC mappings are correct.
• Fix bank A/G selection in X5 Extended Multi Setup SysEx.
• Implement an additional internal buffer for submitted cc0 and cc32 after program changes, tracking the writing state.
• Add defMsb and defLsb for initializing default MSB and LSB, when the MSB and LSB registers haven't been written yet.
