QuadraSynth PlusPiano vs. QS Series

Posted by Jon Deutsch on November 18, 1997 at 22:16:21:

I just got a used QuadraSynth Plus Piano used from my local music store. I have 10 days to return it if I don't like it.

I've been looking for comparisons between the QS+P and the QS-series, to no avail.

Can someone comment on what the QS-line offers over and above the QS+P (and visa versa)?

THANKS!
