I have an expression knob hooked up to the expression pedal jack on the PBC and works it fine when I move it but a lot of the time it triggers itself without me moving it. I have it controlling the mix knob of my Strymon Timeline and at random times the mix of my delay changes and I can see the green light on my timeline turn yellow indicating that a change has been made. Is this a software thing or a hardware thing with my expression knob? I have another expression knob hooked up directly to my big sky controlling the mix as well and have no problem. I've switched the expression knobs and the same thing happens with both when they're hooked up to the PBC.
Also, when I calibrate the expression knob on the PBC, the sweep starts off fine and then jumps up real quick to around 80% when the knob isn't even halfway turned and then it slows down until the knob is fully turned. When in use, the PBC reads that the expression knob is at 50% when really it's at 10% or less. I'm assuming it's the pot value of the expression knob I'm using? Doesn't make sense to me because they work fine and seem true when connected directly to the pedal I'm controlling.
