i was trying to save my sequence but i ended up wiping out..

my internal memory and now the flashcard that comes w/ the mpc is saved as the internal memory, and when i tried listening w/ headphones there was no sound? wtf's going on? i tried a different pair and it didn't work either its definitely the mpc, what should i sdo?

you probably saved everything but the program. When you save to the internal memory its all or nothing meaning everything in there is wiped out and replaced with the new info.
