Wobble would be nicer :p
Is that some poizone i here? either that or sytrus. anyway nice chilling halloween sound in the beginning. cool melody too. If you want some real sounds to work with though get omnisphere, nexus 2, vanguard and some dubstep samples. there so many other vst's out there i thought id just list a few. :P I dont make dubstep so idk the best for the genre, i just know you could make some killer shit with the right sounds.
