Discussion about the Korg PolySix synthesizer

I would potentially be interested. It would depend on cost and MIDI
features. As far as I know, my KLM-367 does actually work, although it
is half patched with hook-up wire. I would only be interested in the PCB
only; the rest I could do. Also, if people need chips programmed, I can
do most types, at cost + postage. I'm in Perth, Western Australia.

My PolySix pretty much doesn't get used at the moment. In the least it
needs a re-tune, and I suspect some caps may be dead.

I also would like either MIDI or CV/gate control to integrate it with my
rig. So, does anyone know how good the MIDI implementation is for Old
Crow's design? I seem to recall that it was pretty basic. Maybe good
enough, anyway. I did try chasing down another design for a CPU
replacement board, that was pretty feature rich, but I think it is no
longer available.

I think my PolySix may just end up in a rack, as it is mechanically
pretty dysfunctional.

Cheers,

Oli
