Discussion about the Korg PolySix synthesizer

Peter,

The act of you placing your DVM probes in-circuit is changing the 
eletrical characteristics of it. Hence, the changes in the sound. Did 
you I hear you right? Did you just say that the MG, PWM and effect 
frequency controls aren't working either?! If so I would be looking 
for disconnected tracks on the KLM-367 as a priority!

I'll get you some comparisons after the weekend.

Have a good one,
Andy

If you'd rather take this topic offline rather than bothering all 
these good people with this lengthy topic then please be my guest. We 
can post the answer when we have it!
