Compact and expressive, the Arturia Keystep mk2 is a portable USB-C MIDI controller keyboard and sequencer sporting 32 slim keys with both velocity sensitivity and aftertouch. Loaded with deep sequencing capacity—including 64 steps with eight-note polyphony, and an arpeggiator with nine patterns and 16 modes—this keyboard is a lightweight yet powerful idea machine.
The Keystep mk2 features intuitive touch-capacitive pitchbend and modulation controls. Full transport controls and an OLED screen make it easy to keep a handle on your productions. When your creativity needs a little spark, the Keystep mk2 offers a one-touch phrase mutation and generation control, chord and scale modes, and the ability to chain, evolve, and transform sequences with precision and ease. Connectivity is versatile, with modern USB-C for host connections, power, and MIDI, full-size DIN 5-pin MIDI I/O, 3.5mm TRS sync I/O, a pedal sustain/expression input, and four CV/gate outputs via 3.5mm for gate, pitch, Mod 1, and Mod 2. The Keystep mk2 includes a USB-C to USB-A cable.
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 real-time shaping, while built-in chord and scale modes make new musical phrases effortlessly explorable.
Ideas Machine
KeyStep mk2 is a generative idea 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, and then transform it. Use Mutate to hear new variations on the fly, try a different octave, adjust note lengths, add silences, overdub additional notes, and record bend and wheel automations—keep your ideas evolving with immediacy.
Compact Design
Slim, travel-ready, and built to fit anywhere, KeyStep mk2 delivers studio-grade features without the bulk. Whether onstage, 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 four CV outputs—Pitch, Gate, Mod 1, and the new Mod 2—now configurable as velocity, aftertouch, mod wheel, and more, all ready to control modular and other hardware with expressive precision.
