Discussion about the Korg PolySix synthesizer

Just noticed that all of the customer's presets sound bad, but a patch that I 
created to "check things" with sounds very pure and completely without 
distortion, don't know if this matters in the big picture of the tuning issue.

Installed the 50k trim pot in place of R93 and is seems to do little, however I 
am able to get the first three octaves tuned to an "acceptable" degree.  Still 
can't get the top end right, and if I trim to get the top octave correc, the 
rest of the tuning sounds awful. Tried replacing IC31 for giggles but that did 
nothing.

His national tour starts in 1 week.
