Xenos Soundworks has released Futurist Dubstep and DnB, a soundset for the Massive software synthesizer by Native Instruments.
Futurist Dubstep and DnB contains 50 patches and covers a wide range from aggressive, angry wobbles, growls and reeses, to sublime post-dubstep sub basses. Also included are extra sound effects, pads and leads.
Each patch in the soundset uses the Macro Controls, the vast majority of them using all 8 for maximum tweakability and expression. The soundset ships in a zip file containing both KSD and the new NMSV format.
