ooo, ahh. MIDI is a great way to go -- it's a pretty cheap way
(file-wise) to get a lot of functionality, not just for music but also for
things like reverb and triggers, etc. This is what a lot of CD-ROM folks
are doing: instead of storing all those expensive soundfiles, just store
the MIDI control data and assume the user's soundcard is General MIDI
compatible (this means that control numbers are assigned to specific kinds
of sound, so that program #1 is always a piano, for instance). Most are,
these days...and at 16/44, at that...

Of course, this assumes the presence of a soundcard or of other MIDI
devices. Still, MIDI is how a lot of sound people work these days, and
it's a good way to enrich the VRML environment relatively cheaply.
(Who was it said that good sound is the easiest way to improve one's
graphics --?)

MIDI compatibility at some point would be great --
-- maybe a little late for 1.0, though -- Cheers, Maribeth

P.S. Just saw your last post, Len. Does MIDI answer your criteria?
Some MIDI devices currently let you get at ADSR and other such parameters
through control messages....
