Discussion about the Korg PolySix synthesizer

If the oscillators are not running, then you could still get a ticking 
sound due to the VCA opening and closing.  As I recall you have a scope,so maybe focus on just one voice and see if the oscillator is running when the 
LED is on (which means the gate signal is high).   It seems unlikely that all of 
the oscillators would have died at the same time.  

Set the filter to all the way open, and the sustain to max, and the mode to manual,not a patch, and find IC33 of voice 6.   Pin 7 of that chip should be the 
output of that voice.  And the same point on the other voices should be their 
outputs.  When you hold the key down, you should have a nice waveform atthat point if the LED is on.   If not, work your way back from there to see 
where it stops.

 Subject: [PolySix] Re: Key assign mode issue
   
    I replaced the cpu (thanks) and now my six diodes light up when testing (super). However... I still have issues. I only get a ticking sound. My filter and resonance are working but all working keys produce the same ticking sound. (Changing the wave shape does not alter this). So I still have more issues.If anyone has any suggestions, I'd appreciate the guidance.Thanks again.  #yiv8031889093 #yiv8031889093 -- #yiv8031889093ygrp-mkp {border:1px solid
