I think I've solved my problem. I noticed that the preset kept switching to C18, losing some of my routings. I think the MRCC was receiving control message from something in my setup, which was switching the preset. Setting the MRCC Midi Cntrl to an unused port has kept my presets where they belong (on User 1), and PC messages are now being sent.
