Which is it ?
In general:
There are 2 ways of calibration,- you calibrate using the MINI´s keyboard CV as a reference,- or you have the CV generated by the MIDI kit as the reference.
The CVs generated by MINI´s keyboard electronic are more inaccurate than these of a good MIDI-CV interface.
Minimoog´s keyboard devision in semi-tone steps is done by resistors which have tolerances and might suffer from age too.
Incoming MIDI note events (note numbers) representing semi-tone steps too are digitally accurate.
Given the fact your MIDI-CV interface is in excellent condition, it will produce slightly different CV per semi tone step compared to the MINI keyboard.
So,- if you calibrate the MINI to the CVs generated by the MIDI-CV interface, the MINI itself will be slightly out of tune across it´s own keyboard.
If you calibrate to the MINI´s keyboard,- it will be slightly out of tune over MIDI.
AFAIK, there´s only one MIDI kit for the MINI allowing to play the MINI over MIDI and w/ it´s keyboard in tune,- the Linntronics.
Have also in mind, if the MIDI kit itself is faulty (damaged or by age), you better avoid calibrating your MINI to that kit.
But it´s also possible your MINI needs restoration,- or both, the kit and the MINI.
Eventually it´sa idea to throw out the it 1st, then calibarte the MINI itself according to the proceedures described in the manual/servixce manual and see if it works and how good that calibration is.
In that case and w/ luck, you can play a fine instrument as it was and is and be sure is working as expected.
MIDI comes 2nd row.

Hi there,
My first post I think in this group. I have a Minimoog D with MIDI kit built in under the keyboard.
The kit seems to receive MIDI messages ok, but it need to be calibrated, in a way, because it plays way off key...
Does anyone have any experience with this?
Merry Christmas!
