Playability
KeyStep Mk2 features a velocity-sensitive 32-note slimkey keyboard with aftertouch for expressive control in a small footprint. Pitch and mod touchstrips provide intuitive realtime shaping, while built-in chord and scale modes make new musical phrases effortlessly explorable.
Ideas machine
KeyStep Mk2 is a generative ideas machine as much as a controller, with its polyphonic step sequencer, 16-mode arpeggiator, pattern chaining and creative tools like pattern mutate all working in symbiosis. Build a riff with the arpeggiator, convert it into a sequence then transform it! Use mutate to hear new variations on the fly, try a different octave, adjust note lengths, add silences, overdub additional notes, record pitch bend and modulation automations – keep ideas evolving with immediacy.
Compact design
Ultra-slim, travel-ready and built to fit anywhere, KeyStep Mk2 delivers studio-grade features without the bulk. Its shallow profile keeps you close to the instruments you're controlling, while its intuitive layout enhances playability and seamless integration on stage, in the studio or at the heart of a hardware rig.
Hardware connectivity
Hook up to virtually anything: alongside USB-C MIDI, 5-pin DIN, sync I/O and a pedal input, KeyStep Mk2 features four CV outputs - pitch, gate, mod 1 and mod 2 - now configurable as velocity, aftertouch, mod wheel and more, ready to control modular hardware gear with expressive precision.
