Xpantastic!

I once tried to re-wire a guitar volume pedal to hook to the pedal inputs to my M12.  It worked, but only in a really narrow range (like the center 1/4 of the pedal's travel), it was "railed" beyond these limits.  I did this by tying each of the the pot's three legs to each of the tip-ring-sleeve conductors of a stereo 1/4" plug.  I figured adding a resistor to the upper and lower legs of the pot would fix the "railing" problem, but never got to it... anyone else ever tried this?  I still have hooked up to this day.

Yes, a pedal in general is just a pot you move w/ your foot,- but this not only for "volume" ...

Manual says clearly: Pedal inputs for PEDALS or FOOTSWITCHES.

All common momentary switches work as expected if the polarity is right.
A PEDAL works like a LEVER ( of a Matrix12 p.ex. and a LEVER is a pot )
If it works or not depends on the pedal or pot used.
You cannot use any pedal.

Lever 1 and Pedal 1 exist independently for each voice, Lever 2 and Pedal 2 are universal controllers, - this does not depend on midi in any way.

Ah, I think I understand. Thanks for the answers!

The pedal is just a pot, a volume control (up/down).

It looks like I'll have to get a PC-200 MKII controller with a pot pedal 
socket. I used to have one but it broke so I got a MK 1 and it's not as 
good. With this I should be able to mess around with the Xpander's 
filter by pedal. :-)
