you definately should get your hands on the Kawai VPC1, its designed to play computersounds, and has the touch of a real grand piano..... it however has no buttons, or knobs or wheels...just 88 piano keys, all black and white
I went into "heat" when I first read this, and then I went into menopause when I saw the weight.......65 lbs!
Kawai specs Great idea though....I really have difficulty playing those "plastic" keys on most keyboards.
