Keith,
Do you have right hand voices, or is the whole keyboard silent? When I try it, I have right hand voices sounding but no APC until I move the split point up from C1. Then all works as it should on my KN7000. I'm using Version 1.5 - very curious.
Are you using an expression pedal? If so, have you tried unplugging it? I had weird changes in volume after playing a sequenced song. Thought that it was a bug in the OS. The problem went away after I unplugged the pedal. Even though that fixed it, I still believe the problem exists because of a programming glitch in the OS.
Regards,
Walt
