Is it possible to set up an expression pedal (either using the jack on the unit or midi) so that, i.e. when in the heel position the effect (in this case the wah/filter) is off and then anything other than full heel is on and then controlling the effect? Almost like the heel position (0) = toe switch off on a real wah. or would the only way to access the wah/filter effect (or any other for that matter) be by having a foot switch turning effect on/ff separately or having a preset with it on?
I hope this makes sense. Restated, I want to have the wah exp pedal sitting there heel down and off and basically any movement will turn it on and sweep, and then off again heel down.
Am I looking for a unicorn?
