A 32-key velocity-sensitive controller with polyphonic step sequencing, arpeggiator and four CV outputs for modular gear

  • Velocity-sensitive 32-note Slimkey with aftertouch for expressive play
  • Polyphonic 64-step sequencer plus 16-mode arpeggiator for deep idea generation
  • One-touch Mutate transforms patterns instantly to keep creativity flowing
  • Four configurable CV outputs (Pitch, Gate, Mod 1, Mod 2) for modular rig control
  • USB-C MIDI, DIN MIDI, 3.5mm sync I/O and pedal input connect to virtually anything

Portable Controller & Sequencer

The Arturia KeyStep mk2 is a compact USB-C MIDI controller keyboard and sequencer built for producers and performers who need expressive playability in a small footprint. Its 32-note SlimKey keyboard adds velocity sensitivity and aftertouch for dynamic control. Chord and scale modes help users explore new harmonic ideas without deep theory knowledge. It fits easily into a backpack for mobile production or a tight studio desk.

32-Note SlimKey Keyboard with Aftertouch

The velocity-sensitive 32-key bed with aftertouch is the single specification that determines whether this controller matches a player's technique. It provides polyphonic expression in a shallow profile that keeps hands close to external gear. Musicians requiring a full five-octave range or hammer-action feel will need a larger controller. The slim keys favour synth-style lines and fast sequences over traditional piano repertoire.

Sequencing Capacity & Connectivity

The onboard polyphonic step sequencer stores 64 steps with eight-note polyphony, while the arpeggiator offers 16 modes and nine patterns for generative composition. Pattern chaining and mutate functions extend arrangements without a computer. Four CV outputs — Pitch, Gate, Mod 1 and Mod 2 — plus 3.5 mm sync I/O, DIN MIDI and a pedal input integrate modular and vintage hardware. Users needing more than 64 steps per pattern or additional CV voices will hit the limits of the built-in engine.

Questions about this item

How does the 64-step polyphonic sequencer work when I am playing live?

The sequencer holds up to 64 steps with eight-note polyphony so you can build a pattern, chain it with others and mutate it on the fly while the keyboard still sends notes and CC data to your synths.

What does the USB-C port actually carry besides power?

USB-C handles host MIDI, device MIDI and power in one cable so the controller talks to a computer, tablet or USB host without a separate adapter.

Will the four CV outputs fit my Eurorack patch cables directly?

Each of the four CV/gate outputs uses a 3.5 mm jack for pitch, gate, Mod 1 and Mod 2, matching standard Eurorack patch cables.
