Arturia KeyStep mk2 37
Compact, Powerful, and Inspiring Controller and Sequencer
The KeyStep 37 mk2 is a versatile controller and sequencer that combines intuitive playability, advanced sequencing tools, and comprehensive hardware and software connectivity.
Whether you're composing melodies on a modular system or controlling virtual instruments in a DAW, it integrates seamlessly into any workflow, fostering exploration and creative fluidity.
Expressive Playability
The KeyStep 37 mk2 features a 37-key SlimKey keyboard with velocity and aftertouch sensitivity, offering expressive control in a compact form factor.
Dedicated capacitive touch strips for pitch bend and modulation allow for intuitive sound shaping. Chord and Scale modes facilitate harmonic exploration and the creation of new musical phrases in a simple and natural way.
A true idea machine
Much more than just a controller, the KeyStep 37 mk2 is a true inspiration generator thanks to:
Its polyphonic step sequencer
Its 16-mode arpeggiator
Pattern chaining
The Mutate, Spice & Dice creative tools
All these elements work in perfect synergy.
Create a riff with the arpeggiator, convert it into a sequence, then transform it instantly.
Use Mutate to generate new variations in real time, transpose your sequence, adjust note durations, add rests, layer additional notes, or record pitch-bend and modulation automations.
Your ideas evolve immediately, without interrupting your creativity.
