For anyone who has read this far in this thread, you might be interested in my blog:
The Halls of Valhalla
I have been writing about general reverb issues, as well as some more techie stuff. Not nearly as techie as on this thread, but it might be of interest to y'all. My latest writings have been about modulation (definitely inspired by zmix's sound files), as well as general ways of working with the controls in reverb algorithms. I also talk about the "lost" Schroeder algorithm in an earlier post.
Feel free to comment on the blog if you are so inclined. I'll be hanging around this thread as well, flipping my virtual nickel in the air and chewing on my virtual toothpick.
