There's certainly no problem opening Max4's 

 files, which are ASCII text. I just tried a handful of random 

 (binary) files; a couple failed with "bad header", but they were in a directory called "Data" so they might have been binbuf data files of some kind. The others opened fine. So: weird data files aside, it should work.

my file had no extension, I added .mbx and now it works...

While being on this topic: Here's a lovely patch which works fine in Max 4 but gives me coll nan's in Max 6. Anybody knows why?
