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
