RE: [motm] silly question
2000-04-18 by Tkacs, Ken
I know exactly what you mean. I am constantly finding circuits (without VC) that I want to tinker with, but me feeble EE knowledge can't figure out how to replace a pot in a schematic with a CV input. I wonder if there isn't some generic circuit that could do this. An optocoupler? Something like that? I would love it if someone could whip up a schematic that could directly replace, say, a 100k pot, that adds a CV in jack, attenuator, and initial settings pot. Then maybe just values need to be tinkered with to replace other value pots.... A small table could show those values... Maybe it's oversimplifying to hope for this...?

My question probably doesn't make much sense, and with my limited electrical knowledge, I probably won't explain it very well either. What I was thinking of was a circuit designed to simulate a pot. A simple circuit with a CV in, a CV attenuator, and 3 wires to replace the pot, 2 to provide a constant resistance and one to vary according to CV. This would be a simple solution to those of us who want voltage control over the freq. on their MOTM-420's or the wet/dry control on a spring reverb. Maybe I'm out of my mind here, and this is an impossibility, but it's worth throwing out. Let me know if it's possible or if it would involve too much circuitry. -Nate
