voices : More SA and SA2 voices, also more edit options and finally some topline piano sounds. A new synth engine for really fat synth sounds.

Styles : more lively, if you could add part of the Karma technollogy to the styles they would be so much alive. On top of that i would love to have more styles that give that lively feeling we know from Ketron, so the next style engine could also use some audio parts. I.e. styles need a lot of work and not all sound like typical Yamaha but also have a lot o styles with a less pollished more alive sound.

pads : it should be possible to transpose the pad based on the chords played in real time.
