Glad you got the DAC cal fixed. I did a complete cal of my Polysix recently. It was a little tricky in spots. I think it would be tough without an oscilloscope.

Tried the calibration again, and as foreseen, no issue with LED 5 being stuck on the DAC calibration step, 1 & 8 they are.


I don't understand the part of KLM-366 calibration with VCF and Resonance: it seems that Cutoff is at Max at the knob ('Normal') but the manual says to look for 0V at CN5-7.


My voltage sweep seems to be off: I don't get the full range of -5V +5V for Resonance on CN5. I don't know if that is correct.


Calibration without an oscilloscope cannot be done properly, so until then, I would like to thank Bob and Johannes and all those who responded and helped, including those who shared their experience in the past.


Regs,
