Thanks,So, with just an inexpensive keyboard that has MIDI IN, is it possible to play notes with the UNO (sending MIDI data), and then send some kind of MIDI data to change the instrument? I haven't seen anything that tells what bytes to send to tell it to play a particular instrument. So that I could play, say the piano, then with a button press or something, switch to an organ?
The shield is also capable of playing several tones simultaneously (maximum polyphony of up to 31 sounds!).
