If you are willing to look outside Csound and don't need real-time, I
can recommend Cool Edit (www.syntrillium.com), which you can download as
shareware.  Cool Edit includes a large number of sound processing
algorithms, including reverbs.  The shareware version has the limitation
that you have to select at start-up which effect groups you want to use
for the session, but you can save the results (I think).  Even the full
version is cheap ($50) and well worth it.
