The Arturia KeyStep mk2 is a compact 32-note controller and sequencer that combines expressive Slimkey playability, advanced sequencing tools, and extensive hardware and software connectivity in a lightweight portable format.

Playability

KeyStep mk2 uses Arturia’s velocity-sensitive Slimkey keyboard with aftertouch, giving musicians an expressive keybed in a small footprint. Capacitive pitch and modulation strips deliver smooth real-time shaping, while integrated chord and scale modes allow instant harmonic exploration without complex setup.

Creative Sequencing

This controller integrates a polyphonic step sequencer that records in real time or step time, supporting up to eight voices per step. Pattern chaining enables full song creation, while tools like Mutate, Spice, Dice, and the addition of ties and rests transform sequences into evolving compositions. An advanced 16-mode arpeggiator provides multiple pattern types, from traditional cycles to generative, experimental textures.

Design

Slim, lightweight, and portable, the KeyStep mk2 balances stage-ready durability with studio-grade performance. Its OLED display and push encoder streamline navigation, providing clear control over sequences, modes, and parameters in any environment.

Connectivity

The KeyStep mk2 integrates seamlessly into both vintage and modern workflows. It includes USB-C MIDI for DAW synchronisation, full-size MIDI DIN In/Out, CV and Gate outputs, Sync I/O, and a pedal input. Four assignable CV outputs (Pitch, Gate, Mod 1, Mod 2) ensure flexible control over modular setups, while modern USB-C power minimises cabling and maximises portability.
