Discussion about the Korg PolySix synthesizer

My guess is that when one thing is not like other "identical" things,
something is wrong.  Of course, that would only account for one voice
not working.  When you press a key six times, it cycles through the
voices, so if that were bad, I would expect to hear 5 notes, and one
silent.

I'm not saying it's *not* bad, because it very likely is, but there
are other problems.

For the most part, just about every problem that I've seen or heard of
on a PolySix is either from it sitting around (the keys are oxidized,
and you have to press them very hard to make sounds or the capacitors
are dried out), from somebody harming it (dropping it, hooking too
high of electricity to it, etc) or from the back-up battery exploding
(pretty much all other internal problems).  Out of habit, the area
around the battery is where I would start looking.

Oh, to answer your question, you would want to get a small powered
speaker (from a local electronics store probably.. Radio Shack in the
US has them) and touch the wires to the outputs of the chips while you
are playing notes.  Putting it in Unison Mode and holding a key down
should do the trick.  Of course, do this very carefully so you don't
short out anything to a power rail.
