I just finished building this woodwind controller for my son’s birthday: https://hackaday.io/project/12315-teensiewi-woodwind-usb-midi-controller
It is my only USB/MIDI device so I had never tested MIDI over USB on my Zynthian before. I plugged the TeensieWI into the Zynthian’s USB port, selected a sound and it worked! Very happy about that! Hope my son likes it when he receives it this week.
(I reconfigured the internals of my Zynthian and haven’t made a new top panel yet, so the lettering is upside-down and the knobs from China never arrived. I guess I’ll have to print some 
)
