How Do You Erase Factory Settings?

When I turn my MPC on it's loaded with default samples, programs, etc. And the mixers have default filters and pans on them.

How can I permanently erase all of this for good?

turn autoload off

Is that an option with the JJ software?

I don't see it on my MPC. What the manual says isn't what JJ lets me do.

if your using jj then go to either the load/save screen. f4 should say aload. turn that off

When turning autoload off, does this erase it from memory or just prevent it from loading up when you power on? Is there a way to delete the stock samples to free up more memory for more of my own samples?

i'd imagine you could just turn off autoload and then reboot the mpc to clear samples from memory.
