Arturia KeyStep 37 mk2 — Compact MIDI & CV Controller with Built-in Sequencer

The Arturia KeyStep 37 mk2 is a 37-key MIDI and CV controller and sequencer that bridges hardware synths, modular rigs, and DAWs. It pairs a Slimkey keybed with a polyphonic step sequencer, 16-mode arpeggiator, and four CV/Gate outputs.

What sets this controller apart

Each CV Mod output can be routed to a syncable multi-wave audio-rate LFO, an ASR envelope, or a rise/hold/fall C-envelope — modulation sources that normally need extra Eurorack modules. A global ratcheting engine (1×–4×) and a customisable Mutator reshape sequences live.

Keybed, aftertouch, and performance controls

The playing surface uses Arturia's Slimkey design — narrow, velocity-sensitive keys with aftertouch.

• Keys: 37 Slimkey keys — wide enough for two-hand parts and full chord shapes
• Velocity & Aftertouch: Yes — expressive dynamics for MIDI and CV outputs
• Pitch & Mod: 2 capacitive touch strips — smooth bends without mechanical wheels

MIDI, USB, CV/Gate, and sync I/O

Connectivity is this model's strongest asset — it speaks MIDI, USB, CV/Gate, and analogue clock simultaneously. Ships with a USB cable and manual; runs on USB-C bus power.

• USB-C: Class-compliant MIDI + bus power — plug-and-play with DAW, iPad, or standalone synth
• MIDI DIN: Full-size 5-pin In/Out + Thru — talk to any hardware synth
• CV/Gate Outputs: 4 (Pitch, Gate, Mod 1, Mod 2) — assignable to velocity, aftertouch, mod wheel, LFO, or envelope
• Sync I/O + Sustain: 3.5 mm clock In/Out + TRS pedal input — locks to vintage gear and Eurorack tempo

Built-in sequencing and generative engines

The sequencer and arpeggiator run independently of a computer.

• Sequencer: Up to 64 steps, 8-voice polyphony — record or program chords and full arrangements
• Arpeggiator: 16 modes (Poly, Walk, Pattern, Random…) — generative patterns with Phrase Arp remapping
• Generative Tools: Mutate, Spice, Dice — instant melodic and rhythmic variation
• MIDI CC Banks: 4 banks × 4 CCs = 16 assignable controllers — hands-on control of external gear
