Sonus Dept. has released three sound libraries, all available for free download (optional donations are possible):
Dark Mass is a sound library for Native Instruments Massive, featuring 20 presets oriented towards dark atmospheres, weird electronic sounds and cinematic FX. It uses Massive, mostly known for its powerful basses and leads, in a completely different way, making it suitable for soundtrack, ambient and experimental composers.
Industry Trailer is a sound library for Kontakt providing deep percussions, hits and sound FX to build up aggressive, industrial and cinematic rhythms. It is an appetizer for the full Industry library currently under development.
Stylus Beats is a small Kontakt library and sample pack (WAV / AIFF) featuring all the sounds of a famous bizarre cheap beatbox.
