I need to do a bit of midi translation but don't really want to learn C or java etc. I'm running a NI B4 clone and want to drive it from a multikeyboard Yamaha. The B4 has 120 sequential presets, normally selected using a 10 way switch (bank) and 12 keys. I have 22 buttons available on the Yamaha, say 1 to 10=A to J (bank) and 11 to 22 = 1 to 12. If i select A (bank 1) and then 2 I need to convert this to preset 2 If i select C (bank 3) keeping preset 2 needs to convert to 38 i.e, 3x12+2 If i select C preset 8 needs to convert to 44 i.e, 3x12+8 If i select F (bank 6), keeping preset 8 need to produce 6x12+8=80 etc. Following conversion I need to output the appropriate control change. Anyone have a simple idea of how to do this? TIA Ray.
