As a follow back to the list, just wanted to say that Miller kindly sent me some old .pat files. This file format seems to have been included in MAX 2 and I see MAX 8 can still open them, but can't save them as .pat anymore, and saves them as .maxpat instead. This is what happens since MAX5.

Pd Extended and Purr Data can load ,pat and save them as such. Pd Vanilla can still open .pat files but fails to save them properly as such. It seems Miller took it out thinking it didn't make sense anymore and that MAX 5+ couldn't really open it anymore. I guess we'll bring it back to Vanilla the proper saving as .pat though :)

Cheers

Hi, I see Pure Data can still, to this day, open and save .pat and .mxt files. If I get it straight, this text file format started in max v2 and went on until v4, right? I'm looking for files in this format to check how they look and to see if I can actually open them in Pd. 

I actually tried saving a .pat file and open it in Max but couldn't do it...

Moreover, Pd Extended can open .mxb, an old binary format that I believe got rid in MAX5 along with .pat and .mxt.  So I'm also looking for patches saved as such to test it out in Extended.

So, any idea where I can find these?

Thanks
