making changes to pgm and resaving.

If I create a pgm in MPC Editor or MPC, load the sounds in my MPC and then change different parameters in my MPC is there a need to resave all the sounds? It's what I've been doing because if I don't the sounds won't load, but basically it saves the wav's as snd's and there's a redundancy. I'm wondering if that's avoidable?

Save PROGRAM ONLY.
If you save that to the same folder as the already saved associated sounds it should load the sounds when you load the new program.
No need to save the sounds everytime unless you have added more or changed their names.

I must be effing something up cause when I do that it didn't save the sounds and upon my last attempt it just saved bank A.
