Just got a MC3 and I’m having issues with assigning expression messages on anything in a HX Stomp. I can see the position on the MC3 when I move the pedal but that is it. I’ve tried to emulate Exp2 and to assign a midi cc message as shown in the Morningstar youtube video explaining how to do it. I first tried a volume block, then the output block, and then the gain on a compressor. I’ve tried to set it and tried the learn function in the MC3. I can’t get it to work and don’t know what else to try. I know messages are getting to the stomp because I can send messages to change presets and snapshots. What am I doing wrong?
