'Raw Dubstep 2' from Equinox Sounds and Fix-A-Flat Productions is a sample library that features nearly 1 GB of Dubstep Construction Kits. With over 200 dark and grimey eight bar loops, this makes for a perfectly combustible Dubstep laboratory. These Construction Kits are available in ACID/WAV and Apple Loops formats. The sounds are 100% royalty-free.
