In SAINT we are testing a reverb based on FDN (feedback
delay networks), an algorithm developed some time ago
by J.O. Smith and D.Rocchesso and that at the moment
turns in a 5.1 configuration on Merging Technologies' Mykerinos
card. I do not exclude that it will be released in a next future, together
with the group of effects, in a general purpose form. I have (still
informal) contacts with Davide and his students for that...

Needless to say that I don't like too much the idea of
another parametrization :-))

Best regards,
