Thanks to everyone who suggested exporting to .mid. Unfortunately, 
though, this doesn't compltely help. The sounds I'm working with are a 
combination of sounds generated from SoundNote and sounds imported from 
.wav files. EmitSound doesn't have any trouble with these combined 
sounds, but it seems impossible to export them. So unless I can convert 
the SoundNote (midi) sound into some other format, I'm kind of stuck, 
since it's not possible to go the other way and convert the .wav into midi.

Yeah, that's my question. I don't see how to get this to work. I could 
not get the example in the documentation to work, let alone anything else.

What I finally ended up doing was to play my sounds with EmitSound in 
Mathematica, and record them on a handheld digital audio recorder (which 
I have anyway, for purposes of recording the various music groups that I 
play in), then upload from my audio recorder to my computer, and save it 
as one big happy .wav or .mp3. This did work, but was kind of a clunky 
way to do it. I'd be happier if I had a direct way to convert from 
SoundNote / midi into .wav (or other non-midi format) from within 
Mathematica.
