I am trying to setup an expression pedal to use as a volume pedal with Guitar rig 7 Player within Logic Pro X. Both the Logic "midi learn" functionality and right click on the control knob approach do not work. The midi controller is being recognized within logic (input 21 and goes from 0-127 when I move the pedal as it should). When I use the logic midi learn approach, it correctly identifies the controller and the knob I want it to control, but it doesn't do anything. When guitar rig is started as standalone, the midi learn approach works. I am at a loss. Does this functionality only work with standalone guitar rig? Any thoughts or suggestions?
