I personally find it easier to make the sliced folders offline, then plug in the USB on the MPC and just copy to a CF card or my internal HD (add on, but like I said you can get a maxed for 500GBP very likely).
So that's for WAV's I already recorded from a turntable or ripped off CD's in iTunes.
The Recycle over a SCSI wire dumps are extinct now. Recycle 2.2 finally removed. Also I'd have to check if it had worked on the SCSI port enabled MPC's, but the rack ones I'm sure off it.
So yeah I'm talking the ease offline as you prefer. But you can always have a set of audio cables going into an MPC from your audio interface or slightly less optimum but totally useable option of a 1/8" headphone to stereo 1/4" cable from your computer's headphone jack or other 1/8" SPDIF output.
Good luck with whatever MPC you use, and don't forget in the Studio Environment/Production Techniques forums we talk about software and many things besides MPC's.
So hope to see you here again man.

EDIT - I told you debauch knows more than me.
