[sdiy] Resonance control taper ?

I was just thinking of doing the nonlinear response conversion in
analog. Have a linear pot output a voltage that goes through a log or
exponential converter to a VCA/OTA in the signal path that controls
resonance. This is of course more circuitry, but eliminates a
specialty pot that may become hard to source.

As soon as you have programmability, all the controls *do* become 10K linear because they're just a panel being scanned and having their values sent to DACs. If you need a specific reverse-log curve for a specific control, it's a look-up table away.
