Thanks for the suggestion @weightless, I've now tried to load the library in 32 and 64 bit Vanilla and Purr Data but with no luck and have tried everything I can think of- adding to search paths and startup flags, moving the library to the 'extra' folder, installing via Deken... nothing is working.
I'm trying to use the timbreID library in Purr Data, downloading the Mac release here (http://williambrent.conflations.com/pages/research.html) and adding it to the startup search paths, but to no avail, the PD window shows error 'timbreID: can't load library' every time. I've been scratching my head and reading forums all afternoon but can't find a definite answer, is there something I'm missing? Is it a compilation problem?
Thanks in advance for any advice you can offer!
