Gain using the LM13700

[Dud]

I don’t know if that’s can help you but look here

CV Pan: mono -> stereo

Yeah, if that’s the case I’d tweak the input stage a bit, and also the output stage (make the 470k smaller and the 1k output resistor larger). Ignoring the input stage for a bit, here’s the VCA core with the OTA and the I-to-V converter: [image] EDIT: The CV in this drawing is relative to the Iabc input potential, which is two diode drops above the negative supply, not 0 V, so with a 12 V supply the CV in the simplified circuit above is shifted by 10.6 V. The CV input circuitry needs to comp…
