Welcome to the forum.

A .PAT file in the context of BIAB is like an .INI file to Cakewalk by BandLab and, I suspect, other DAWs. Its function is to translate the output of a program to the correct patch (sound) in a hardware MIDI synth. I’ve written several. But this doesn’t seem at all what you are describing.
