Arturia will release KeyStep mk2, the next evolution of its acclaimed compact controller & sequencer. With a 32-note Slimkey keyboard, generative sequencing tools, and deep connectivity via CV/Gate, MIDI DIN, and USB-C, KeyStep mk2 lets you spark ideas in your DAW, pilot any synth, or patch modular without breaking your flow.
The original KeyStep became a modern classic by giving musicians a simple, reliable way to bridge modular, hardware, and software instruments.
With KeyStep mk2, that formula has evolved in every way that makes sense – becoming more creative, more connected, and more immediate than ever. It introduces Mutate and generative tools, a bright OLED display, and a redesigned sequencer and arpeggiator that make idea generation effortless. KeyStep mk2 is priced at $139 in the USA and 129 € (or $129) in other regions.
Patch into modular, trigger drum machines, and control synths from past and present. With USB-C reliability, DIN MIDI I/O, assignable CV outs, and pedal support, KeyStep mk2 is ready to command any setup – live, in the studio, or on the move.
