just to add to this you can't low pass everything. So much of the sound had to do with the 12 bit samplers of the day. It wasn't that it was really filtered it was just the lower sample rates of the day that added to a more muffled sound and a more distorted sound. While you can come close to this sound using methods like mentioned here nothing matches the machines used themselves. And S900s are dumb cheap these days. The most popuar setup in hip hop until like the late 90s was the sp1200/s950/900 combo as far as I know
S950 w/RAM expansion+MPC60II w/RAM expansion = GOAT hip hop setup.
