I don't really post in here, but I went to Juilliard in the 70's majoring in Performance Piano and I have 23 years playing live in rock bands as a keyboardist. I still have quite the home studio...
I did have an Ensoniq VFX-SD for about 2 months. I just couldn't get used to the crappy keyboard, and the polyphonic aftertouch was pretty much useless to me as a result. The sounds were okay, but there were far too many better instruments at the time, and I sold it off quickly.
