mpc kits

does all the mpc's come with the same kit? like sound kit.. because ive heard some of the mpc1000's sounds..( kit ) and the mpc2500.aND THEY KINDA SOUND THE SAME. but do the xl and 4000 have the same kits.. like the 3 song that is already loaded on the 2500 is like a r&b track? and they have guitar things...
