It depends what sort of audio interface (soundcard) you have (or want to get), and what you want to do . Do you want to record the pc's output into your mpc to sample ?> Or do you want to record your beats from your mpc into your computer? Do you have the 8-output board in mpc ?
Really, man, it's as easy as looking at the back of your equipment and figuring out what needs to be connected to what (i.e. are you sampling from computer, or recording from the mpc). You gotta be more specific in telling us what you want to do if you want a proper answer.
