Discussion about the Korg PolySix synthesizer

Hi Don,

That's very helpful.

I tested from pin 1 on IC31 across to the pins mentioned on both chips and pin 4 in both are display differing resistances, whereas the others are fine. Do you recommend bridging for to something in the chain ? 

I very much appreciate your help.

Best wishes,

Tony
