RE: Lots of pots not working, MG, VCF, EG.

I never said IC6 sends CV, I only said it's connected to CPU's T0 through the DATA signal.


Also, I didn't find any other pot than Cutoff or FX Speed which changed the LEDs on DAC calibration, but did find interplay between the two (which appears to be expected), but my LED 5 is still stuck ON.


Haven't ruled out some issues with the front panels completely yet since I will be doing the resistance measurements.


Specifically, I want to understand what could cause IC18-P12 (Res) to always have voltage variations no matter what potentiometer is turned. First thought, it's a short somewhere, but it could be something else.


Modded KLM-367 to use the new DAC chip and testing calibration again, plus more exploration on the leftmost front panel, and perhaps the resistance values check is the plan for today.
