Expression Pedal

Iʻm having problems hooking up my Dunlap mini volume top the MC6. It almost seems like Its not getting enough signal. When I go to calibrate it, it doesn’t register a number, its like its in-between two numbers flashing. It definitely reads that something is plugged in. Any help?

Iʻm up to date on all the software on the editor as well as the firmware.

Are you using a TRS or TS cable? Do note that a TRS cable is required.

I’m encountering this exact same issue with a SP-H9 using TRS. MC8 with 3.8.3 firmware
