[Wandering Kid]

agreed on crystal. its sick.

superwave p8. you can grab it at kvraudio.com. especially if you like a jp'esque sort of sound - it doesnt actually do very good supersaws but you can get some nice underworld type fuzz out of it. all the better that it costs nowt.

muon tau. another freebie, this time a 303 clone. because everyone should have a 303 sound in their arsenal. it can get pretty fat too but without a little EQ/compression work right from the word go, the bass on it can be blurry as hell.

reFX claw. freebie cut down version of reFX beast which is a 4 oscillator monster. claw rips (painfully so at times) so keep the level down or risk tinitus.

karnage. you'll need to search the kvr forums for this i think. one of their forum members (kriminal) knocked up this plugin for gratis. watch out - its fairly brutal and some of the patches will make your head ring. suitable for noisy drum and bass/hard house/hardcore.
