Very cool idea. On a tenuously related topic I was just playing around
with some VST plugins that have randomization functions built-in: for
instance, the dfx Transverb has a randomize button that came up with
some pretty bizarre stuff, so I started thinking about how Snd could
incorporate such routines. It should be fairly straightforward even now
from the Listener, yes ? But I was also thinking about wiring in a
randomize switch for some of the effects. Any thoughts on this notion ?

(And yes, it was Calder. Didn't Earle Brown take Calder as an
inspiration too ?)
