Now this is interesting. Most of the demos are very pop-oriented and to me don't sound that great, but the concept of layering samples is well-known and this tool seems to make that very easy. Apparently there are a bunch of new samples of real drums here that you can combine with each other and with drum-machine samples and mangle them to your heart's content.
One of the things I never liked about NI's drum sets (Abbey Road) is that while they might sound good on their own, they didn't always cut through in a mix without a lot of tweaking. This tool aims to fix that problem.
Now, if you're primarily looking for natural-sounding acoustic drums, this may not be the best thing. It's unclear how it handles velocity variations, round-robin, etc. Would like to hear from anyone who decides to take the plunge!
Cheers,
Eddie
