amazing. So there is a 5k Ohm pot in it, probably.

10k Ohm linear. The problem is to get a good enough pot. I did not
even know Oberheim had a pedal... It depends on the mechanics how
much the axis is under pressure. Usually thats where the pot wears
out and produces dust which then create bad contact on the tapers.
Other really cheap potentiometers wear out on the tapper itself.
I am using a blue Bourns (series 92...) for may years in a Schaller pedal.
My Penny & Giles faders also work for 15 years without problem (the
Alps died after less than a year).
>Or is it possible to define some "active zone" from the EDP?
only by soldering resistors ;-)

nono, once you buy a pedal...

me too! We need to fix that.

That could work! It would only take one more wire, so with a stereo
cable...
It would not serve for me, though, I need to control it while playing.
