I just got a Mobius, and I want to be able to use my expression pedal for the Wah, and some of the other functions on the Mobius (like reducing bit rate on the Destroyer engine). Normally, my expression pedal controls decay and mix on my BigSky. What I want to have happen is: When I hit the switch on an IA page to activate the Mobius' Wah I want the expression pedal to change function and control the filter sweep on the Wah When I turn off the Wah using the same switch, I want the expression pedal to resume normal reverb control. Do I do that using the System -> ExpPedal -> ExpPedal settings block within the "Edit Local Buttons" page? Or is there a better way to do it?
