I am using a Dunlop Volume (XL) as an expression pedal. Enter the expression ‘jack’ into exp 1 on the QC. Using a TRS cable. Regardless of what I try on the QC or the pedal, I consistently get heel-down max and toe-down min. I want just the opposite. What am I missing?

If it’s a DVP1XL model, there should be an internal switch for the heel/toe polarity. Try switching it.

I believe it is a DP 3 xl. I tried the push button inside to no effect.6

in the meantime, are you using the workaround of inverting the min and max values?
