Maybe your pedal has a knob or setting switch on it that may need to be set. Check its design and schematic for such. I must confess, I know nothing of midi and I recieved a Moog EP 2 pedal with my PitchFactor. It didn't work or register with the PF and I spent 3 hours looking for reasons why on line and I was at the point of taking the pedal apart when I found a hidden/ more like disguised knob called an Attenuator which I needed to set clockwise full right. After that, I plugged it in per instructions and all worked great. Hope this helps your pedal problem.
I will probably have a lot of use for the forums with my lack of knowledge.
