Hallo,
I've finally put the current state of RRADicals into the CVS on pure-data.sf.net but it might be, that you won't be able to access it until tomorrow because of Sourceforge latency. A current snapshot is at http://footils.org/pkg/rradical-cvs-040423.tgz in the meantime.
On CVS, RRADical is in the directory "abstractions/rradical" which contains several subfolders, of which the following need to be in your pd-path if you want to use or create RRADical patches.
memento control tpl instruments effects
To install you need to add something like this to .pdrc:
-path /rradical/memento:/rradical/control:/rradical/tpl:/rradical/instruments:/rradical/effects
Beware that you will need a whole bunch of externals for this. You need them all. Everything. But first and foremost you need "pool".
In "usecases" you will find several unsorted example patches using the RRADical patches for your copy-paste pleasure. In "memento" there also is a tutorial which introduces some of Memento's features.
As this is a really big collection, which is currently rapidly growing (today I converted the "d-angriff" patch which took my just 15 minutes!), you might at first want to start with the document in the "doc" directory. This is a readable (still slightly unfinished) version of my talk on RRADical which will be held at the LAConf2 next week in Karlsruhe. Be the first kid on the block having read this. There is the reStructuredText file in rradical.rst, or use the html- or pdf-files created from this.
Well, have fun.
Ciao
