Well, since you (presumably) use the drum to create tones by playing them so quickly, then it would fit under the category of Extratone. Extratone was a name someone in the speedcore scene called music that was designed to use drum machines at speeds that would cause the drum sample to sound like a tone instead of individual hits. Usually around 1000 BPM. He found the exact speeds on a number of machines and made a pretty technical writeup about it.
