Shows off music studio menu, that allows anyone to jump in and out and choose any of the following: lead, rhythm, bass, drums, keyboard.
Ah, well, those are the in-game tracks that are possible, but it doesn't necessarily mean it'll support a midi keyboard. Earlier we saw the guy demoing the keyboard sounds on his guitar.
Still, if it doesn't support it, it seems like it ought to at least be possible through an update...
