When you're finished with a song, you can backup the song folder to another media (pc hd, dvd, tape, etc..) and then delete all but the last version folder on your MPC. I gave up on saving pointers to samples soon after I got my MPC. It's so much easier just saving the entire memory to a folder. Now with mass storage available, there really is no excuse not to do it this way. Of course, I always am open to suggestions for other save methods. Anyone?
