U have to work on a MPC to know that feel... it has a unique "swing" to it... basically... it sets certain notes off to give u more of a real drummer feel, by applying the swing to your drum tracks...Dr.Dre, kanye, J-dilla... they all use the MPC and if u notice they all got that "swing" to their beats, that shit that just make u wanna nod your head... U can get the same results from computer sequencer programs like ProTools, FL studio, or Sonar, they have preset quantinization settings that u can apply to your midi tracks... and they are pretty close to that "mpc swing"
