Arturia KEYSTEP 37 MkII Compact Midi Controller and Sequencer- KEYSTEP37MK2

Arturia KeyStep 37 mk2
MIDI Controller and Sequencer

Compact keys, deep sequencing, and hybrid studio control in one inspiring creative hub

The Arturia KeyStep 37 mk2 is a compact MIDI controller and sequencer built for musicians who want hands-on playability, fast idea generation, and seamless integration with hardware and software setups. Designed as a universal creative interface, it combines expressive keyboard control with advanced sequencing tools, making it equally at home in DAW workflows, modular rigs, and portable production setups.

A velocity-sensitive 37-note Slimkey keyboard with aftertouch gives players expressive control in a small footprint, while pitch and modulation touch strips provide intuitive real-time shaping. Chord and scale functions make it easy to explore new harmonic ideas, and the polyphonic sequencer and arpeggiator are designed to keep inspiration moving. With creative tools like Mutate working alongside pattern-based performance features, KeyStep 37 mk2 is built to help transform sketches into evolving musical parts.

Connectivity is a major strength, with USB-C MIDI, full-size MIDI DIN I/O, sync I/O, pedal input, and four CV/Gate outputs for controlling modular and hardware instruments. The OLED display, clickable encoder, and RGB feedback streamline navigation and editing, while the compact format keeps it practical for desktop studios, live rigs, and mobile music creation.
