Great value taster selection of REX files built from over a dozen other packs. A 'best of' Loopmasters Drum & Bass, Dubstep and Breakbeat styles if you like. For professional and aspiring producers, this will give you a good arsenal of rhythmic and tonal building blocks if you're into these genre's. I've grown to trust Loopmasters selecting and curating abilities and would always 'go to' their products first as they have really tuned into the specific needs of recording artists and producers.
