Hi! I’ve been very excited by the TB2, amazing design. I’ve actually breadboarded one using the design files, except I cannibalized 13 keyboard keys from an old dead Yamaha consumer keyboard. It works great! I was wondering though if you’ve looked into adding USB MIDI considering that the DUE has USB host capability? since most MIDI keyboards now only use USB, I think this would be awesome, and shouldn’t require any extra hardware.
