Discussion about the Korg PolySix synthesizer

Hi!

Oooooo, sorry, Mr. Hooke (May I call you Meat?) - the VCOs in the
Polysix are *discrete*, linear (Hz/Volt) items.  Since you're a member
of the Yahoo Groups Polysix club, I believe that they have a schematic
posted (or directions to one), indicating this.  If not, I can tell you
that it's in my Polysix Service Manual.  Just a few transistors, etc.,
making a saw/pulse VCO.  Sadly, they're not 1V/Octave, as with so many
other machines of the time, so it's not easy to interface 'em -
Basically, you need MIDI to do that.

There a a couple of nice MIDI interfaces available, depending upon how
deep your pockets are.  There's an Austrian company that offers a
bare-bones interface for less than $200 USD, and an Austro/Swedish duo
that has a full, comprehensive interface for about $400 USD.  More
information should be available at the many Polysix websites - Just
Google 'em! :-D

It really is a fine machine, capable of many different sounds.  And,
for a single-VCO machine, it's pretty flexible too, thanks to the
built-in chorus/phase/ensemble, and arpeggiator.  

OK - My two cents worth.  Please feel free to flame/argue/support --
whatever.  Thanks for the bandwidth!
