Thanks for explanation Bernie,
I don't use midis so I couldn't appreciate what you were saying. I use styles and I can move up or down a full octave to best suit the right hand voice (accordion). I have found the styles don't follow (be out of tune) if I only move up or down a notch (12) at a time for some reason on the Audya. I could transpose anywhere I wanted with the MS40 and everything was fine. I'm thinking maybe there is a "lock" on somewhere in the menu but haven't found it. I only sing rarely in a dark room alone :-) so that's not a problem. There is so much we will never learn as you have mentioned because the manual is just an outline. The other day on the Yahoo/Ketron message board, another helpful member gave me a step by step instruction on how to load a new style (or pattern) into the Audya... I would never have guessed how to do that.
