Well, Vosim was developed for speech, so I guess at least it was
useful for that, but personally I didn't really play that much with
it. A single vosim generator as in my patch will exhibit a signal with
one strong formant. Combine three of them, and you can do some almost
nice vowel sounds by putting the formants at the typical frequencies
for a, e, i ...

Although vosim is a granular technique, it's purpose is mainly in the
realm of what Miller calls "designer spectra" in his book. There he
also describes some more flexible techniques.

They are just abstractions, you could get them from CVS and then use
them. Both really help with creating and managing many copies of an
