I don't have one but if it's anything like the original PLANET PHATT then it's a bunch of good drums, hiphop efx, and basses with a bunch of hard to use sample styled presets that can be edited to work pretty well. I would guess the MO PHATT is a souped up version of the PHATT.
Might wanna shoot this question by the other hiphop cats if you haven't already.
Peace.
