Korg PolySix
From: "william.b.fox" <wbf@aloft.att.com>

The PolySix was released pre-MIDI.  I bought one from Mike Metlay and it
is a nice one vco/vcf/vca machine.  Has a unique shorus circuit.
Probably one of the best retrofit kits could be added to make it MIDI.
Unfortunately, it is no longer available.  The rights have reverted back
from Korg to the designer.  (Mike knows who that is.)  With enough
interest, the designer might sell another run of kits but there hasn't
been enough interest.  Ricard Wolf sent me the documents for the
retrofit that he designed.  Maybe someday I'll get to it.  It does look
quite thorough!  For the archives, here are the stock features:
