Arturia KeyStep mk2 - Keyboard Controller & Sequencer 

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.

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

Slim, travel-ready, and built to fit anywhere - KeyStep mk2 delivers studio-grade features without the bulk.
Whether on stage, in the studio or foregrounding a hardware rig, it's easy to integrate into any setup thanks
to its intuitive layout and compact build.

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.
