How are written ".all" files?

Do someone know the structure of a .ALL file, the one that contains all tracks/sequences/songs for a project?

I'd like to write a small piece of software to analyse/convert them in other formats and I need a scheme of how MPC stores informations inside of them.

Thanks-a-lot

i remember Stereoroid had the schematics for the program files
please keep me informed about this project. i'm very interested.

I've tried on www.stereoroid.com, but I did'nt found any clue about that.. If someone knows where MPC's sequences schematics could be retrieved, please post them

many thanks
