Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

I'm also under the impression that the grounding on the Polysix is
problematic (or better: can be problematic). That this must have been an
issue at least for the early units is clear from the technical notes in the
service manual.

The various problems I've encountered with different units are at least in
part grounding related. I can't really make sense of everything yet so I'll
run a few more tests once I have a bit more time.
