hi guys, i just got a pair of morley M2 passive expression pedals that i plan to use with my Helix.  Problem is when i try to assign one to the volume pedal block for example and i use the learn controller function. the pedal goes from 0 to 100 and back to 0.  i saw on a previous post someone rewired their volume pedal to work, but the Morley doesnt have a traditional pot but rather a slider inside, now it still has 3 poles, I've tried jumping the ring and sleeve together but that didn't work. i
