Just checked, buth TRS and Mono worked fine, TRS seemed to work out of the box as I would expect…. Heel = 0 Toe = 90 (need to calibrate I guess)

Interestingly Mono worked the other way and I had to play with the knob on the side to get it to go from heel = 100 to Toe = 0

Either way it works, but would need a little calibration work.

Tried it on a couple of stock presets ModEchoVerb and Blackhole.

I double checked and I do have the L version.

Cheers
