Arturia KEYSTEPMK2 Compact USB Controller And Sequencer (White) - 32 Keys

KeyStep mk2 is the ultimate compact controller & sequencer for DAWless workflows or hybrid setups. It keeps the core essence of the range - powerful, playful & connectivity-first while evolving it in ways that matter most.

It serves as a catalyst for creative ideas, uniting generative tools, intuitive control, and performance-ready sequencing in a modern design.

KeyStep mk2 is a one-of-a-kind ideas machine with no computer or software required to unlock its full creative potential.

Designed for two main users:

• Synth & Modular Musicians needing keys and connectivity in a compact controller.
• Bedroom Producers wanting powerful and creative functionality that fits their workspace.

When you “need keys,” the focus isn’t on the keys themselves — KeyStep enhances another product. It’s the bridge that keeps your setup tight, connected, and creative.

KeyStep mk2 builds upon the original with new generative tools like Mutate, a clearer OLED interface, extended connectivity, a more powerful sequencer and arpeggiator and a refreshed design
