The Pro said,"I think that softsynths are the future. There's a lot going on in the softsynth field, which is why so many companies like Midiman, Edirol and Novation are making new MIDI/USB controllers. Creamware's new Noah may be an indication of things to come: softsynths in hard cases. It's still years away but I can see where soon we all might be using softsynth arranger packages in a few years (Tyros-OS softsynth arranger for PC/Mac would be nice, and I'll bet the engineers at Yammy are working on it)."
Frank Rosenthall said that his system cost less then the Tyros with impecable sound quality. 15 gigs of sound ROM!!!!
I think that unless keyboard mfgs address this phenomenon they will be left making controllers. Portablility and reliabilty issues would have to be addressed of course.
