Calibrating Voyager Pitch CV output

I need a permanent offset of the pitch cv output. It tracks beautifully across the range of my dot com oscillators, but I either need to tune them up a third or offset the voltage before going into the dot com. is there way to just adjust a trim pot on the inside of the voyager ? Thanks

It can be done with the CP251, the mixer has an offset control.

I know that, it's how I'm doing it now. But I don't want to have to use that anymore. I hate tying up the mixer just to get the pitch right. I was hoping for an internal fix

Knowing the complexity, and the high sensitivity of some trimpots inside a Voyager, I wouldn't mess with them and risk messing up the internal tuning. An external solution is WAY more preferable, believe me.

Yeah I found out from moog that it's not possible, but I did contact Roger at synthesizers.com and its possible to adjust the the base frequency of the q106 via trim pot on the back. So it's all good
