The rjdj-svn is the canonical location for rj-lib, but of course as it's
GPL/BSD it can be copied anywhere. For contributions we can only accept stuff
that either is BSD or transfers copyright to Reality Jockey as we want to avoid
legal problems as a distributor of rjlib to others ("others" currently includes
Apple, so we have to be extra-extra cautious about this.)

Do you mean to "biquad~" or what is "bequad~"? biquad~ in Pd should be a lot
faster, but I didn't benchmark it.

No, I hadn't seen this. It doesn't seem to need the [samphold~] which would be
cool to avoid anyway. Could you elaborate the algorithm a bit and how it's

I think, currently it's probably a bit slower because of the sin(), but maybe
that could be put into a tabread~.
