Hallo,
rrad.pattseq is a sophisticated pattern sequencer using the Memento state saving system (memento >= 0.5 required). Some planned features still missing, but here ya go with a preview version. Get it at http://www.pure-data.org/Members/fbar/patches/rrad.pattseq-0.0.1.tgz
Or/and see how it looks here: http://footils.org/cgi-bin/cms/?show_article=18
Also there is a new release of Memento with a tiny new feature, that was needed for rrad.pattseq. Get memento-0.5 at pure-data.org as well: http://www.pure-data.org/Members/fbar/patches/memento-0.5.tgz
ciao
