I need help in split mode. I want to create split performance, for example bass in left hand and dx piano in right hand.
How to create note shift -12 only in right hand or only in left hand +12.
As you have probably already figured out, not with the Transpose buttons!
It is accomplished by editing the individual “Part” parameters. Here’s how:
Press  to select PART 1 (buttons 1-4 are now PART SELECT)
Press [F4] TONE
Press [SF1] NOTE SHIFT
Here you can Note Shift each Part up/Down as required by semitones.
Press [STORE] to update your program
Extra Credit: the TRANSPOSE function changes what the MOXF keyboard Transmits; the NOTE SHIFT parameter is changing what the tone generator reproduces, and is set per individual Part.
