terminate a Moogerfooger CV externally

[Crackers]

HI, how do you terminate a Moogerfooger CV externally? Like if you plug a TRS patch cable into the feedback CV on an mf-104z, the feedback control knob on the pedal does not work correctly? I am building an A/B box with a bypass switch to switch between 2 pedals or Moogerfooger CV inputs and 1 expression pedal. I need to know how to terminate the CV in the A/B box so the Moogerfooger CV knob works correctly when not overtaken by the expression pedal.
Thanks,
