The KeyStep mkII features 32 high-quality slim keys, which support velocity and aftertouch, offering expressive control rarely found in controllers of this size. The two capacitive touch strips for Pitch Bend and Modulation allow intuitive real-time sound shaping, while the built-in Chord and Scale functions make it easy to explore new harmonic paths. This way, every performance becomes more lively, natural, and tailored to your musical needs.

Functioning as a true "idea machine", the KeyStep mkII incorporates a polyphonic step sequencer with pattern chaining capability and up to 64 steps per sequence. The 16-mode arpeggiator (Poly, Walk, Pattern, Random, etc.) includes the new Phrase Arp, which adapts patterns to your notes, offering organic evolution to your riffs. You can start with an arpeggio rhythm, turn it into a sequence, and enrich it with overdubbing, creating complex musical structures with minimal effort.

Experiment freely with the live controls that allow real-time adjustments to Gate Length and Swing. The KeyStep mkII features the innovative Mutate tool, which creates variations in your melodies on the fly, ensuring your setup always remains creative. You have the ability to adjust the note length, add rests, or write automation for Pitch Bend and the Mod Wheel, giving an organic feel and continuous evolution to every musical pattern you create.

Slim, lightweight, and highly portable, the Arturia KeyStep mkII offers professional-level features without the bulk of traditional controllers. The built-in OLED display and push encoder allow for quick navigation of settings and visual confirmation of parameters. Its low profile keeps you close to the instruments you control, while its durable construction and Kensington Lock port make it an ideal choice for demanding stage performances or intensive studio use.

The KeyStep mkII offers complete connectivity flexibility via USB-C MIDI, MIDI DIN In/Out, and Sync I/O 3.5 mm. The highlight of its connectivity is the 4 CV outputs (Pitch, Gate, Mod 1, Mod 2), which are fully assignable to velocity, aftertouch, or mod wheel. This allows you to control modular or analog systems with absolute precision. Additionally, the pedal input supports both Sustain and Expression (TRS), providing comprehensive control over every aspect of your rig.

Weighing just 1.1 kg and measuring 484 x 145 x 50 mm, the KeyStep mkII integrates effortlessly into any workspace. It features Transpose & Tap/Hold functions for instant key and tempo changes, while recording can be done in real time or step-by-step (step recording). Its class-compliant operation via USB-C ensures it is ready for use with your PC or Mac as soon as you connect it, making it the heart of a modern and versatile music setup.
