The Keystep mk2 includes a USB-C to USB-A cable.

Playability
KeyStep mk2 features a velocity-sensitive 32-note SlimKey keyboard with aftertouch for expressive control in a small footprint. Pitch and mod strips provide intuitive real-time shaping, while built-in chord and scale modes make new musical phrases effortlessly explorable.

Ideas Machine
KeyStep mk2 is a generative idea machine as much as a controller, with its polyphonic step sequencer, 16-mode arpeggiator, pattern chaining, and creative tools like mutate all working in symbiosis. Build a riff with the arpeggiator, convert it into a sequence, and then transform it. Use Mutate to hear new variations on the fly, try a different octave, adjust note lengths, add silences, overdub additional notes, and record bend and wheel automations—keep your ideas evolving with immediacy.
