The Drwbar Commander in equipped with a "standard" (5 pin) MIDI IN port as well USB MIDI IN.

They can both be used to merge MIDI in data with thoese generated by the Commander e sends them to both MIDI (5 pin) and USB OUT.

With this release we added a way to "monitor" if MIDI data are coming at the MIDI in ports: when in "ALT" mode the current preset's LED blinks when there is MIDI in activity.

The code is as always on GitHub.
