[sdiy] Original MS20 pitch tracking issue

[Douglas Hock]

Hi everyone,

I recently purchased an ms20 that was sawed in half to be rackmounted, but
abandoned as a project. 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!
Doug
