I haven’t had a chance to install and check this out yet, but, this looks like a promising VST for doing glitchy drums! It was created by Kieran Foster, a programmer from England. I can’t wait to try this until when I get back home… If I ever do. I’ll update with samples when I am able to play with, however, there are sound samples on the site. Here is a description from the site.
Glitch features a pattern-based effects sequencer that takes the incoming audio, breaks it down into user-defined slices, and then applies different effects to each slice. The sounds it generates range from quite subtle to extremely bizarre, depending on how much you tweak the controls.
There are some other VST plugins for your perusal as well, check them out.
