I think my issue is all MIDI related. Which Midi input do you use 1 or 2 (keyb)?
When I map CH 15 to my Keyboard, the style triggers, but I can't get my left hand sounds, it's only right hand sounds the entire keyboard. I'm using a Yamaha Motif.
Another clue something is wrong, I CANNOT set the Split Point. It is set at C3 and when I press SPLIT+Key on the keyboard, it does not change at all.
Of course the manuals are all for the Audya and not the Module, so it's no help.
