I'm certainly no expert on these matters, but is Csound really the right
environment for this sort of programming? Looking at your code, and your
comments, It seems as if you are going to great lengths to get Csound to do
things which it isn't really that good at! I'm *definitely* not saying
that you shouldn't use CSound, I'm just interested in *why* you chose to use
Csound rather than something which is more suited to the kind of work you're
doing - Supercollider, Nyquist or working at a lower level with Lisp and/or
C/C++.

Good luck to you all the same, this could be the future of DSP :-)
