Here's an extensive set of drum-sounds from the DR 660 (played by, among others, Squarepusher, Orbital and the Electric Hellfire Club).
The samples are arranged so you get 8 different drum kits, all mapped the same way.
So write your drum pattern, and you can instantly try it out with 8 different drum kits from standard to electronic (eg., in the Kontakt version, just solo a different instrument).
Or you can mix them, or play them all at the same time for a ridiculously huge drum sound. A great tool for roughing out your drum sounds, and it has some great non-standard sounds on it. The demo just repeats the same drum pattern with the 8 different kits.
