Description
The Arturia Keystep mk2 is a compact yet powerful USB-C MIDI keyboard and sequencer featuring 32 velocity-sensitive slim keys with aftertouch and expanded performance controls. Touch-capacitive pitchbend and modulation strips pair with chord and scale modes for expressive playability. Its polyphonic sequencer offers up to 64 steps with 8-note polyphony, alongside a 16-mode arpeggiator and creative functions like Mutate for evolving patterns. Connectivity includes USB-C, full-size MIDI DIN I/O, sync I/O, pedal input, and four configurable CV/Gate outputs, making it flexible for DAWs, hardware synths, and modular rigs.

Playability
The Keystep mk2 offers a 32-note slim keybed with velocity and aftertouch, delivering expressive control in a compact format. Touch-capacitive pitch and mod strips allow fluid real-time shaping without breaking your performance flow. Chord and scale modes expand creativity by guiding harmonies and keeping ideas intuitive and musical.

Ideas Machine
Its polyphonic sequencer, 16-mode arpeggiator, and pattern chaining work together to spark constant musical evolution. Build riffs, convert them to sequences, and reshape them instantly using tools like Mutate and real-time overdub. Adjust note lengths, add silences, shift octaves, and record modulation gestures to keep ideas moving effortlessly.

Compact Design
Slim, lightweight, and stage-ready, the Keystep mk2 fits seamlessly into tight studio spaces or mobile setups. The shallow profile keeps controls close and accessible, promoting faster hands-on workflow. Its clean, intuitive layout ensures smooth integration whether used alone, with hardware rigs, or inside a DAW environment.

Hardware Connectivity
Designed to connect with almost any setup, it includes USB-C MIDI, full-size MIDI DIN, sync I/O, and pedal input. Four assignable CV/gate outputs—Pitch, Gate, Mod 1, and Mod 2—enable expressive control over modular and analogue gear. Each output is configurable for velocity, aftertouch, or modulation sources, making hardware integration highly flexible.
