Arturia KeyStep MK2 Compact Expressive MIDI Keyboard Controller & Sequencer - White
The Arturia KeyStep mk2 is a compact, expressive controller & sequencer that combines hands-on playability, deep sequencing tools, and broad hardware/software connectivity in one portable unit. Whether you're crafting melodies on a modular rig, triggering patterns on vintage gear, sequencing soft synths in your DAW, or performing live with a portable setup, KeyStep mk2 adapts to your workflow. It builds on the proven success of its predecessor, known for strong sales and widespread adoption, and enhances the experience with even more powerful features designed to meet the demands of today's creators.
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 musical ideas flow effortlessly.
With its polyphonic step sequencer, 16-mode arpeggiator, pattern chaining, and real-time performance tools like mutate, spice/dice, and tie/rest steps, KeyStep mk2 is a generative composition machine as much as a controller.
Slim, travel-ready, and built to fit anywhere - KeyStep mk2 delivers studio-grade features without the bulk. Whether on stage or in the studio, it's easy to integrate into your setup thanks to its intuitive layout and rugged build.
Hook up to virtually anything. KeyStep mk2 includes USB-C MIDI, MIDI DIN In/Out, CV/Gate outs, Sync I/O, and a pedal input - making it equally at home in modular rigs, vintage synth chains, or modern DAW workflows.
