I am an electronic drummer and an acoustic drummer. Not an acoustic drummer with electronic drums. And my piano feels nothing like my little kazoo. I hope you get the picture. I hear alot of talk about how well this or that drum pad or brain tracks.
Tracking refers to how well the drum brain senses each pad hit.
For example, a module that tracks well would detect each pad hit and play a sound at the right volume every time. Copyright 1999-2000, the Electronic Drum Web.
