I don't understand that these 2 lines show any relationship between an
<audio> tag and a MediaStream; there's no automatic link from
getUserMedia() to an <audio> tag.
If getuserMedia() is going to return a stream in midi format, I would
expect that to be
navigator.getUserMedia({audio:midi}, gotAudio)
navigator.getUserMedia({midi: true}, gotAudio)
or something like that.

Would you expect the OS to automatically convert the MIDI codes to an
audio form if the media stream is connected to a speaker? What if it's
connected to a PeerConnection?
