CDP info:
It's a suite of small command line programs that do various things, thusly:

GROUCHO - assorted signal processing. If you have Cool Edit on the PC you
probably won't need a lot of these fucntions, at least from the point of
view of general utilities. But there are some interesting granulation,
brassage and distortion progs to play with.

SPECTRAL SUITE - various programs that work with files generated by the
CDPs's version of PVOC. You can stretch spectra, blur them, tune them to a
fixed frequency, cross-synthesise, interpolate, and so on. You can do a lot
of this in Csound now with the new pvoc related opcodes and a stack of sine
oscillators. But the CDP version doesn't load the entire analysis file into
memory in one go, which makes it possible to work with much longer files.
And the options are more complex.

CSOUND EXTENSIONS - a small collection of utilities. Includes score
processing (add, remove, and scale columns in a score), granular synthesis
(a bit redundant now with grain), REMIX (motif editing and generation, and
more - way too complicated to describe here), and WEDGE (big chunky scores
with diverging textures.)

If you ask Archer (Endrich) nicely and promise not to tell anyone, you can
get hold of the source code for these and modify them yourself. It's
supposed to be a collaborative effort, so any changes you make will be
incorporated in the package. 

The whole system is about to be revised and redesigned with better
integration between its different parts, but it's too early to worry much
about what it will turn into once that's done. The standard system has
plenty to play with now.

Hope that helps,
