Hi,
are you actually wanting the apc function to play your left hand piano part ( ie arpeggio'/chords) while you play your melody with the right?
I created a set of piano arpeggio pads a while back for the kn7 from a midifile. It's a great way to create a left hand part, and really simple to do.
If that's what you're trying to do please let me know.
best wishes
Rikki
