Hi Joe,
Wrt the change on Z3TA are you referring to bank change or program change? If you mean program change then it works just the same as all the others > use the arrows to select program change in the APRO LCD display > Use the rotary knob to change programs.
WRT Banks I havent tried that. Sorry. I'm going away today so won't get chance to look at that til next week.
I hope the other advancing Presets is working for you now, and he split keyboard thing.
