Step Into Your Next Idea: The Arturia KeyStep MK2 is Here

Posted on by

Arturia has officially unveiled the KeyStep MK2, an exciting evolution of its beloved compact controller and sequencer. The original KeyStep became a studio staple by bridging the gap between DAWs, hardware synths, and modular rigs. The MK2 builds on this legacy, refining the design and adding powerful new features for generative creativity and hands-on control.

It’s more than just a keyboard; it’s a musical nerve center designed to pilot any synth, sequence any modular patch, and spark new ideas in your software, all without breaking your creative flow.

  • Performance Strips: Capacitive touch strips for pitch bend and modulation, plus new live sliders for Gate Length, Spice, and Dice.
