  • The piano, reimagined

    Fusing the power of technology with the organic beauty and emotion of the piano, Stratus is a vast, dynamic new instrument that will add depth, movement and colour to your music. Made in collaboration with BAFTA-winning Icelandic composer and producer Ólafur Arnalds, this versatile, multidimensional tool bends space and time through an intricate network of polyrhythmic piano performances. Awe-inspiring patterns and atmospheric clouds of harmonic refractions swell and die away at your fingertips, unfolding based on what you play and instantly sparking new ideas.

    Instantly playable and easy-to-use, Stratus is presented in a bespoke interface made up of eight multi-layered piano and synthesizer matrixes, each offering a unique sonic experience — plus detailed customisation options and mind-blowing warped sounds, offering a full spectrum of emotion.

    Stratus works by taking a single note and repeating it according to a curated rhythm, splitting the rhythm between the two self-playing pianos while at the same time relocating the note up or down the octave based on a curated level of randomness, that chooses whether or not the octave should jump. Where our Evo Grid technology is triggered by note range, the Stratus matrix works by voice groups — dependent on the order in which you play the notes, and how many you play.

    Mics over a piano

    The making of Stratus was my way-over-the-top way of getting over a writer's block I had been suffering from. The excitement and thrill of creating something so unlike what I'd done before sparked countless new ideas.
