I use a volume pedal.....to get the swells of the accordion...I have it set to control only the RH voices, leaving the accompaniment at the same level.
Ian.......thanks for reminding me about using a volume pedal. I used to use one with my "accordion" sound on the DX7 way back when, but I've been playing a Roland these last few years with no separate output for the right hand.
Come to think of it, I'm not even sure I would have figured that out myself.....using a volume pedal on that output....I've been so used to "across the board" volumes with very few individual controls! I have to start looking into all those options I now have on the PA3x.
