Re: What grooves doest Mark Knight - Jooris Voorn and D,ramirez use....
Answered this already but seems to have been deleted in another thread. Anyway Joris Voorn uses a lot of samples that are cut, re-edited, layered, low passed, hi-passed and eq-ed. He also does a neat little tricks with the volume automation on a loop to do attacks on particular beat and to bring the "silence" to total silence and cut off any drum tails quite harshly. The purpose of this is to give more space for extra layers.
It's probably the result of all this tinkering and fiddling that gives the final drums their groove. Though you can save audio loops out to midi and import them back in as groove templates too.
