Hello
<br>
<br>
Would not supercollider itself fulfill your demands, as an algorithmic
<br>
composition tool, event generator, event interpreter, front-end, and
<br>
sound-maker, in an emacs environment with gui-building capabilities?

Hmm, Smalltalk is very nice, but not a functional language.

I shouldn't have said that. I don't know enough about Supercollider to
say anything about whether its a functional

language or not.
