ableton has a slice to midi feature....it slices the sample and puts the chops in place on your keyboard or pad controller....
it also has a very simple sampler called "simpler" that is very easy to use.....i have put a whole song in live and chopped it up using simpler then used the slice to midi feature for the fine chops...i drop the chops in a drumrack and then play them how i want with the controller...
as far as being like an mpc...i dont think any software ive heard of comes closer than live...go to the ableton site and check out the "drum racks" video...a drum rack is basically a virtual mpc...and if u have a pad controller or mpc the samples can be mapped out to your pads....there are 128 pads for each rack and its easy to navigate so u can dictate which 16 pads are live at any given time...each pad also has its own device chain which can be loaded with effects, other instruments, or other samples...
