MIDI over USB

Be sure to restart your Android device from time to time. The MIDI backend of Android is a bit buggy. See this thread:

Disconnecting/reconnecting Android MIDI devices causes app to hang

Hi @lukealpha, I’ve been in investigating this bug for a few hours now and - although I’m sure there are a few bugs also in the JUCE code - it’s definitely triggering bugs that are very likely android system bugs. I’m in contact with one of the engineers at Google who wrote most of the android midi code to figure out exactly what’s going on. I’ll let you know once I know more.

and this bugreport:
