Hi all, i don't really know whether this already exists in some library... it's a Max-like prepend object (not exactly the same but compatible).
Grab it at http://www.parasitaere-kapazitaeten.net/Pd/ext/prepend If you can't find it, wait another day and/or reload your browser cache... the server's IP has been changed.
greetings, Thomas
