I play a midi accordion and just recently purchased the XD-3. Very nice module. What I want to do is sometimes play the accordion with a selected RH voice and left bass and chord (like the UM PA PA sound of a regular accordion). Now I've figured out how to control the volume of the bass (deep sound) and volume of the chord (like CM, Cm, C7, etc., which is designated as LEFT in the main display). The problem is this: how do I change the voice of the left hand. both the bass and the chord?

Next problem is this: after I've played a few songs with different voices, styles, etc., and want to return to playing just straight accordion (no style) I can't seem to retrieve the volume of the left (bass tone is okay, but LEFT or chord is muted. So far, the only way I can reinstate the left volume is to turn the XD-3 off and then back on.

Thanks for the help.
