Pssst Instruments Preparist: Piano Percussion KONTAKT | 3 GB Forget lifeless, overused samples. Preparist brings you something entirely different - a percussive library created from a vintage Gustav Rosler upright piano, modified, prepared, and played with everything we could find: hammers, chains, magnets, sticks, fists, elbows… you name it. The result? A massive, modern-sounding, organic percussion library that breathes character. Inspirations? John Cage, Krzysztof Penderecki, George Crumb, sonorists, minimialists and avant-gardists.
