Incidentally, I wanted to let the group know that we've sent out the Intent to Ship mail for Web MIDI in Chrome (i.e., we'll move it out from under a flag). Obviously, this does not mean we will not track changes in the specification from here on out, but we think the time is right to gather development partner experience in the real world.
