Just another update,
Once again my work is pushed back. With my car requiring a new part to pass smog and reregister, it's been difficult to get around. It may be more likely for me to simply be able to bring the audio parts (MIDI module, speaker, maybe a controller for demonstration, etc. as posted on the GDoc), sadly bringing the Arduino/wiring-related content may prove difficult.
My apologies for further delays.
