Arturia KeyStep 37 mk2 Midiklaviatuur White

MIDI Controller Keyboard with Built-In Sequencer and CV/Gate

The Arturia KeyStep 37 mk2 is a 37-key MIDI controller keyboard that also serves as a polyphonic step sequencer and arpeggiator, uniting DAW software, hardware synths, and modular Eurorack devices in one streamlined piece. Measuring 547 mm wide and weighing just 1.09 kg, it fits beside your laptop and offers comprehensive MIDI DIN, USB-C, and Sync I/O. For producers wanting hands-on sequencing, this model provides direct control with no tedious menu-diving.

Generative Sequencing and Modular Connectivity

Distinctive from a typical MIDI keyboard, this instrument integrates a generative creative process: Mutate reshapes phrases with controlled randomness, Spice introduces variation, and Dice offers new patterns at the touch of a button. Four endless encoders switch contextually for Seq, Arp, Chord, or Mutate modes, and the per-key LEDs track sequence, bank, and scale info in real time.

Keyboard and Performance Control

Mini Slimkey keys respond to your playing dynamics and include monophonic aftertouch for enhanced expression. Pitch bend and modulation are handled by capacitive touch strips, while live sliders give tactile control over gate length, Spice, and Dice during performance.

• Keys: 37 Slimkey mini keys — compact and expressive, designed for aftertouch response
• Changing pitch or modulating sounds is easy thanks to the smooth, wheel-free capacitive touch strips.
• Live Sliders: Gate length, Spice, Dice — shape sequences in real time as you play

Sequencer, Arpeggiator, and Generative Tools

This model enables stand-alone composition through its sequencer and arpeggiator. The polyphonic step sequencer holds up to 64 steps with 8 notes per step, and the 16-mode arpeggiator generates everything from standard cycles to complex, ever-changing patterns on power-up.

• Sequencer: 64-step polyphonic, 8-voice per step — ideal for recording, overdubbing, and chaining patterns
• Explore arpeggios with 16 modes including Poly, Walk, Pattern, and Random for creative remapping of sequences.
• Mutate / Spice / Dice: Generative variation tools — infuse live sets with controlled randomness

Connectivity for DAW, Hardware, and Modular

With USB-C for MIDI and power, full-size 5-pin DIN for hardware synths, and 3.5 mm Sync In/Out for syncing drum machines, the YRS-23 integrates smoothly into any setup. Four CV/Gate outputs can be configured for pitch, gate, modulation, LFO, or envelope signals.

• MIDI: USB-C + 5-pin DIN In/Out — works with DAWs, hardware, or iPad devices
• Direct CV/Gate outs (Pitch, Gate, Mod 1, Mod 2 at 3.5 mm) let you assign velocity, aftertouch, or mod wheel signals for modular control.
• Sync I/O: 3.5 mm Sync In/Out — synchronize with vintage and modern instruments
• Pedal Input: Sustain / Expression (TRS) — ideal for hands-free control during live sets
