Hybrid control

Command modular, vintage, and modern gear alongside your DAW. CV/Gate, MIDI DIN, Sync I/O, and USB-C keep every piece of your setup talking, and in time.

Generative creativity

Capture a riff, turn it into a sequence, then mutate it. Generative tools and real-time control work together in perfect synergy to keep ideas evolving.

Sequencer mode, arpeggiator mode and controller mode

KeyStep mk2’s modes work in synergy to keep ideas evolving – capture a riff, turn it into a sequence, mutate it, and keep the momentum alive.

Every port, every possibility

KeyStep mk2 is your universal creative interface. Patch into modular, trigger drum machines, and control synths from past and present. KeyStep mk2 is ready to command any setup – live, in the studio, or on the move.

Playability: KeyStep mk2 features a velocity-sensitive 32-note Slimkey keyboard with aftertouch for expressive control in a small footprint. Pitch and mod strips 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 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 Bend and Wheel 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, MIDI DIN, sync I/O, and pedal input, KeyStep mk2 features 4 CV outputs – Pitch, Gate, Mod 1, and the new Mod 2 – now configurable as velocity, aftertouch, mod wheel, and more, ready to control modular’ hardware gear with expressive precision.
