I just got the Mission SP-1 RJM expression pedal and can't get it to work properly. The first problem is that after plugging it in (out 1 to RJM expression pedal jack and out 2 to ext sw input jack both using TRS cables), the light on the expression pedal doesn't light up. It only does when I switch the cables to the wrong jacks (opposite of above). I can actually get my H9 to respond to the expression pedal but it changes presets instead of parameters inside a preset. I've searched for youtube tutorials but can't find anything. It could be the pedal and not the Mastermind PBC.
