apart from browsing the archives at http://lists.puredata.info/pipermail/pd-list/ (note that i am ignorant of any moratoria that might be around), you could also try to:
- save the max-patch as text (with .pat ending) and open it in pd
- use cyclone (i don't know much about that, but this has definitely
been discussed several times on this list)
Thanks.. Iohannes, but my concern is about converting a patch from pd to Max and not viceversa. I didn't find anything except for a very old converter on the pddp site. Unfortunately the pd patches I converted with that don't work.
