Discussion about the Korg PolySix synthesizer

that's really interesting, i have a similar problem - bank D and patch 4.
but i'm not sure about the patch degradation... sometimes i DO get the VCO
modulation but i always thought it was the old patches. it could be exactly
the same as your problem.

i changed the leaked battery, i changed both IC30 and IC31, i also changed
IC22 (the CPU) and repaired quite a few broken traces.

cheers,
jure
