volume pedal

I am looking at a midi device that will take controller msgs from my pedal board expression pedals and convert them to resistance outputs in the fashion of a potentiometer. I want to use that resistance as a volume controller between my keyboard and amp.

I am concerned that the potentiometer will be, by design, linearly scaled, and not as db audio taper.

I wonder how this will affect its use.

Do normal volume pedals use linear or audio taper pots?

Not having been able to find a few years ago a commercially-available MIDI-controlled log volume control, I built one. I don't have the details to hand, but my memory is that it was a simple PIC-based interface using the Intersil X9C303 as the volume control chip. Someone must have found it useful, as it disappeared from my studio after a particularly intense session.
