MIDI feature requests for Audulus

@biminiroad suggested I start a thread for MIDI features we would like to see in an upcoming Audulus release.
1. Send and recieve MIDI messages.
2. MIDI CC message support for triggers.
3. MIDI tempo support in both directions would be nice in the DAW context.
4. Ability to import a MIDI file, store it with the patch and play it back.
