I don't know anything about festival -- will check it out.  I don't know
of any good Scheme intros -- perhaps the "teach yourself scheme"
files at http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme.html
or http://www.cs.utexas.edu/users/wilson/schintro/schintro_toc.html.

On clisp -- the CLM/Snd connection needs the foreign function
interface (it works by finding and changing window properties,
and that's impossible in Lisp itself).

The jc-reverb change was in 6.10 to make all the CLM-style
instruments the same.  The form that uses map-channel (the
old way of using it) is in new-effects.scm.  Perhaps there's
a way to automate this -- it seems like it could tell the context
it's called in -- will check.
