so with mike's help ("Re: [PD] a few beginner's questions") i sorted out the "couldn't create" trouble. also, i figured out the coll file stuff, i've got it all mapped properly, it seems. only: no sound.
warning: 9-zample: multiply defined
and that line times 4. i'm a bit scared of just diving into the patch & subpatches and start changing things around, so if anyone has a tip, i'd be most grateful.
cheers, robbert
