Quick addendum: I started out using a TS cable and the EXP Sweep was 0 - 100 - 0, with 100 at about the half depressed point. I switched to a TRS and the sweep is now 0 - 100, as expected, with 100 in full depressed state. The Pedal is more consistently recognized with the TS cable than with the TRS cable. I will keep playing with it until I figure it out.
