Hi Gary ...yes I know all that and have utilized it alo .....but I want have buttons,knobs/sliders for Everything when I play....the finger is quicker then the foot in my book....let's face it Yamaha has great styles, great sounds already, not much more they can do in that department.. isn't it time they give the "player" more comfortable, bigger,clearer,outdoor ready, displays and easier access to "on deck controls" lord knows they have the room for it. Independent simulatneous Mp3/Smf/Style play like on the Audya & Songbook like the Korg Pa2x...why cant they all learn from each others mistakes?
