Spitfire Audio announced Ólafur Arnalds Stratus

In our fourth collaboration with renowned composer Ólafur Arnalds, we bring you a brand new, multidimensional instrument, based on his acclaimed software: sophisticated midi algorithms programmed to trigger patterns of notes on two identical self-playing pianos. Spitfire has used this model to create a highly intuitive and interactive tool enhanced with unique features, while recording full performances to capture the profoundly emotional, organic nature of the pianos themselves — instantly adding echoes of movement to anything you play, and pushing you to explore new possibilities.
