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

This behaviour is somewhat normal.

Please try the following:

Put the Polysix in manual mode. Tuning knob centered, pitch wheel centered,
no LFO modulation. Switch to Unison mode.
Please measure the voltage at IC31, pin14 for each "C" from bottom 16' to
top 4'and post that here.
