More on the time-critical tuning issue
2011-03-11 by Bernie GREENBERG
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.
