Originally developed by Propellerhead's for Steinberg's Cubase, REX files are now an industry-standard format read by all leading music software. AMG released the World's first REX1 (mono) and REX2 (stereo) libraries and have one of the biggest and best catalogues around still today - our full range of products for REX titles can be found at www.reasonrefills.com so visit there for many more titles and demo downloads. Of course REX files are also the ideal 'food' for AMG's amazing ONE Virtual Instrument too. In the future watch out for more EXCLUSIVE, download-only releases in the future that will only be available here.
