I'll rebute:
76 keys - ---- huge chassis - prefer 61
Fsr keybed - ------ At least the sx is catching up. (baby steps)
Aftertouch -------- never needed/wanted it
6 knobs ------ 6 buttons
9 sliders - ------ you got me there. Sliders are cool
Bigger screen ------- I'm good with 7" (that's what SHE said?)
Better buildquallity -------- it BETTER be for the $$$$$$
More connections - ------ cool to have
More sounds.. ------- So far never wanted for sounds
Sa2 sounds ------- I don't use the SA aspect as much as some
Ensemble voices - ----- this is cool
Revo drums ------- I hear they're cool, but it's a very subtle upgrade
3 types of drawbar organs ------- I just need a good B, and Farfisa
Huge amount of dsp effects - -------Yamaha has always had tons of effects
No build inpeakers (which to me is a pro) ------- HUGE downer - speakers are a must for THIS pro
3GB expansion memmory ------- 3 to 1 ain't bad (bad Meatloaf reference)
3rd party expansions, many more then for psr series ------- We'll see
Dual audio player ------- I like two, but one is fine
Better bigger and more buttons, ------- bigger is NOT better for most of my stages. Bigger, PLUS the extra amps needed .... ------ too much bulk for this guy
Just one man's opinion, and why they will most likely sell gazillions more 900s than Genos'.
