Great players, be they pianists' or synthesists', will always have a certain disdain for "arranger" keyboards and those who use them in a professional venue. It's similar to the attitude that most musicians have about disk jockeys. As keyboardists', who among us is not more thrilled by a "killer" acoustic piano performance than an "arranger" performance....why? because we KNOW the guy can play, simple as that.
