Activating USB MIDI

Hello,

I’m stumped right now: I can’t seem to get USB Midi to work. Only noticing it now because so far I always used DIN Midi.

Is there any menu that I can’t find where you have to actively set Midi Out to USB, like on the Sequentials? Or should it just work?

Tried a number of cables and connections (hubs, direct to computer), nothing… but the Muse does show up in disk mode. Just not as a Midi device.

Thanks a lot for any input!
