ARTURIA KeyStep mk2

Playability

The KeyStep mk2 features a velocity-sensitive 32-key Slimkey keyboard with aftertouch and offers a great playing feel in a compact package. Pitch and modulation ribbons, along with built-in chord and scale modes, make exploring new musical ideas effortless.

Idea Machine

The KeyStep mk2 is as much a creative idea machine as it is a controller. Its polyphonic step sequencer, arpeggiator with 16 variations, pattern chaining, and creative tools like Mutate work in perfect symbiosis. Build a riff with the arpeggiator, convert it into a sequence, and tweak it! Use the Mutate function to hear new variations on the fly, try different octaves, adjust note lengths, add rests, record new notes on top, save pitch bend and modulation automation – keep your ideas alive and moving effortlessly.

Compact Design

Extremely slim, travel-ready, and easy to place anywhere – the KeyStep mk2 offers studio-grade features in a compact package. Its low profile keeps you close to the instruments you control, and the intuitive interface enhances playability and seamless integration on stage, in the studio, or as part of a larger hardware setup.

Connectivity

Connect to almost anything. In addition to USB-C MIDI, MIDI DIN ports, sync I/O, and pedal input, the KeyStep mk2 has four CV outputs – Pitch, Gate, Mod 1, and the new Mod 2 – which can be assigned to respond to velocity, aftertouch, mod wheel, or other controls, providing expressive control signals for modular gear.
