    What is an Evo?

    Our recording expertise and acclaimed Evo Grid technology adds extra dimensions to each sample, offering you an instinctive, ever-changing kaleidoscope of progressive techniques. For the newly initiated, evolutions are hyper-long notes that change sometimes subtly and sometimes radically over time before looping, giving you unexpected results. Evolutions have become widely adopted amongst the composer community as the most effective means of easily writing music that is able to subtly change over time without melodic variation. These textures can be developed, shaped and processed further, offering you a rich range of possibilities.

    The Grid

    Our bespoke, sophisticated Evo Grid interface, inspired by the EMS VCS3 synth, positions ‘pegs’ via an onscreen 12 x 48 grid arrangement, giving you access to recordings across 12 intervals, organised in a grid with an almost infinite number of possible configurations. Instantly select which evo (evolution) sits on each of those 12 key ranges, toggle your pegs, or hit "Randomise" to generate randomised evolutions, replay the MIDI, and no cue will ever sound the same twice.
