It was actually designed for Tom Oberheim's Marion Synth and the initial
batch Dave got from Overheim directly.  Back when the Evolver was still new,
got to see Dave give a talk at the local AES meeting.  As I think has been
mentioned, was facinating to hear how he basically designed, build, and
shipped a synth without ever leaving the house.  I've had the lid off a Poly
Evolver Rack and sure enough it still has the Marion chips in it...

Wonder if there is some way to hack the two unused VCO's to life ( he used
two chips in the original evolver to get 4 filters, but only used two of the
VCOs... )
