If it was WebMIDI that actually transmitted -MIDI streams- (instead of just shoving them, with limited options, at some flaccid GM soundfile) that'd be really cool. Then you could choose your own MIDI playback engine (application, external hardware, ... ).
In an environment that interprets -all- the codes, MIDI's almost unlimited. Hollywood's used it for a long time. It's very undemanding so people could -certainly- mix their music on the (right) browser. And, if people could add javascript routines to it? Ay-yay.
