Just my 2 cents.....
I am a Pro keyboardist (for the last 38 years), I have play from the non-automatic Hammond B-3s, X-66, Electones D2B, E10R, FX1, Hs6, EL90, Ketron X1HD, SD1, to my latest PSR3000 and soon to became a T2 and the Korg PA60to became a PA1X, also I work as keyboard specialist at a music store in Phoenix Az, I have hear people at the store make the T2 & PA1X sound bad......non intentionally, so, I agree, with KeithB and renig....
The player has not just play, but know how to use the keyboard features into an arrangement, so it sounds like a CD but in real time.
