I always have trouble being sure I'm wiring pots the right way. So far I've been lucky, only one thing I've done has the pots absolutely backwards, and that's a glide control in a utility module so I am not terribly concerned.

However, I'm doing the panel wiring for the VCF/VCA in Analog Synth for the 21st Century, and I'm down to the resonance pot. Unlike a lot of VCF designs I've been looking at, the pot is simply a variable resistance in part of the feedback for the filter section, and I can't see from the schematic which end should be which.

To be more clear; this kind of pot is usually wired with one side and the wiper wired together on one side, and then the other side.

So: I want the fully CCW position to be "low resonance" and fully CW "high resonance", but I'm not sure whether low/high resonance corresponds to low/high resistance (in which case I'd wire the wiper to the CW pin) or whether it corresponds to the inverse (in which case I'd wire the wiper to the CCW pin).

Foolishly, I already took most of it off the breadboard to build the circuit board, so I don't remember how it goes and can't easily test it.

Anyone know?
