Frank,
Would I be able to use my Yamaha PSR550 as a controller keyboard? Is it possible to use the existing buttons for program changes, fills, etc.?
Does you controller keyboard have expression pedal input (so that you can change the volume of the lead voices without affecting the accompaniment)?
How will the fact that LiveSynth Pro might be bankrupt effect us in the future? Just to confirm, LiveSynth Pro can play XG voices without any conversions?
