MPC 500, Saving Etc...

when i had all my samples and sequences done, i went to mode, then song, etc and it was song 1 - (whatever it was called), but when i turned my mpc back on it wasnt there. niether were the samples, i tried to do this as best as i could with the manual, if anyone has any solutions for me, id appreciate it a shit load.

thanks

its probably a stupid question, and a really simple answer, any helps appreciated

You have to load the files back in. Press mode then Load. Then scroll thru the files to find what you want. Every time you turn off the 500 all data that you worked on will be erased UNLESS you save them. Its a pain in the ass but thats how it is. Its in the manual.
