As i recall i tried controlling the osc on a moogerfooger ring mod from the cv outs on a SH101 a few years back and had the same sort of problem, which i didn;t have the bits to do anything about then.

I think there's an offset on the moog osc that's stopping it going down to zero when you turn the knob right down, but as you've noticed it's in the way when you try to tune it for chromatic stuff.

Best guess would be to try mixing a little negative voltage in there to take away the offset, and then tune it up from there

Does anyone know how to adjust the slight difference of intonation between e.g. Doepfer A-110 oscillator compared to a moogerfooger oscillator (e.g. in the freqbox) If I tune it at the lowest pitch it gets gradually out of tune going up a couple of octaves.



I have the same problem with my old micromoog vs the A-110. (but worse)

Also - the S-trigg signal is inverted on the moog and at a higher voltage (12v I believe),



I want to control my Doepfer A-100 system via micromoog and and an oscillator via the freqbox...



Any ideas would be greatly appreciated.
