Discussion about the Korg PolySix synthesizer

Effects intensity does seem to work.

I am without a scope currently.

After leaving it on for a few hours, I did get some control over Cutoff, Resonance, but it isn't stable, rather flaky.

Now, the lower LEDs will not light up and after a while will all light up starting from 1 and moving right.

Thanks also to Philipe, I will check that IC5 on KLM 366
