It's been severeal months since my last post on this subject, anyone found an answer yet? I have my right hand (midi accordion) set to channel 1, my left hand chords on ch 2, and the left hand base set on ch 4. Then I set the Audya to receive on Ch 1, 2, & 3. That way when using styles the manual base does not sound. Then if I want to play manually with no style accompanyment I have to go into the menu and change the ch receive for base to 3. Then I also do not turn on the "key start" because I do not want the style accompaniment to play. This is awkward enough but I still have a problem in that the base sound is at least an octave to low (maybe 2) and I cannot figure out a way to change the octave of the base sound. I cannot just do a global transpose upwards because then the chords and righ hand are too high. If you manage to understand all of this and have any suggestions please advise. Thanks, Gary
