The Drumaxx percussion modelling instrument gives you total control over 16 physically modelled drum pads that can be routed to independent outputs for external effects processing.
More than just drum samples. Great, but why should you care when the internet is awash with drum samples? In two words, expressive control. Once a drum sound is recorded, the performance and modulation options are limited to filtering, volume, or similar 1-dimensional effects.
When a single drum sample is triggered in a roll, you get the familiar ‘machine-gun’ effect and it just sounds mechanical. Multi-sampled, multi-layered drums can overcome this limitation but need multi-megabyte or even Gigabyte! drum libraries. Even then, you are still limited to the sounds originally recorded.
