It sounds from his description like the scaling is off. ("..gets gradually
out of tune as I go up a few octaves...") If you just plug into CV2 of the
A110, that has an attenuator built in, so you can adjust scaling there. You
could also try adjusting the CV scaling on the micromoog. If you're not
worried about how it interacts with other CV sources then you could adjust
the CV1 input scaling without worries. (It's possible that the initial
tuning was imperfect, or that your power supply is interacting with it
slightly differently than the one at the factory.)

Best,
Monroe
