SOLVED: C3 has suddenly stopped "seeing" MIDI?

So I played a gig last night, shut everything down, went to setup at home for rehearsal today and C3 is not seeing any MIDI devices. They are connected to the same USB connections and nothing else has changed. Booted up, started C3 and…nothing.

Any ideas?

PS: running latest stable build.

PPS: discovered I also MUST have the USB audio attached as well…my bad, sorry for the post!
