[sdiy] Odp: Original MS20 pitch tracking issue

[Roman]

If you are sure Analog Keys are sending proper scale (mesure it?) and it still does not play even intervals, then look for offsets between Keys and MS20 oscillator. Maybe during action with chainsaw something got damaged and there's huge DC offset added now. If that's the case you should notice better tracking in upper keys than in lower ones.   You say "calibrated both oscillators", so what did you use as CV source during the process? I assume if it's rackmounted it has no keyboard.

I installed it into the rack, powered and wired it up, and revived it.   Everything seems to work perfectly except for the pitch tracking on the oscillators. I'm sending HZ/V out of an Elektron Analog Keys (the racked ms20 has no keyboard) and it's tracking in uneven intervals. I have calibrated both oscillators with a tuner.   I was wondering if anybody here had some recommendations on where and what to look for. I figure some of you might have seen this issue.   Thanks!
