Best stand alone drum rack/machine software that uses low CPU

[ESSBEEDEE]

Hi guys.

I wana have a drum rack stand alone app that will run alongside Traktor, i'll use it to bash out drums and percussive sounds and samples over tracks that i'll be dj'ing.

I could use Ableton for this and just load a drum rack but If there is another option i'll take it.

Anyone know of any good apps?
