ARTURIA KeyStep mk2 Compact MIDI Controller and Sequencer

The Arturia KeyStep mk2 is a portable, expressive 32-key controller and sequencer designed to bridge the gap between hardware and software. It combines hands-on playability, deep sequencing tools, and versatile connectivity for modern producers, performers, and modular enthusiasts. Whether used in the studio or on stage, it provides precise, tactile control over your entire setup.

Featuring a velocity-sensitive Slimkey keyboard with aftertouch, the KeyStep mk2 enhances musical expression in a compact form. Its polyphonic step sequencer, 16-mode arpeggiator, and pattern chaining features allow musicians to capture, build, and evolve complex ideas intuitively. With creative tools like Mutate and real-time recording, users can easily generate and transform musical ideas on the fly.

Compact yet powerful, the KeyStep mk2 integrates seamlessly with both analog and digital systems. Its robust connectivity—USB-C, MIDI DIN, sync I/O, and 4 configurable CV outputs—makes it a universal centerpiece for DAWs, modular rigs, and synthesizer setups. Paired with included software like Analog Lab Intro and Ableton Live Lite, it’s ready to inspire creation right out of the box.
