KeyStep 37 mk2

The KeyStep 37 mk2 is a 37-key slim-key MIDI controller and step sequencer built for hybrid studios and modular rigs. It adds an OLED display, four mode-aware encoders, and full RGB pad feedback to the connectivity foundation that made the original KeyStep a standard in hardware integration. The 37-note keybed carries both velocity and aftertouch, and the sequencer engine supports polyphonic sequences with generative tools for probability and randomisation.

Connectivity covers USB-C, MIDI DIN in/out, four assignable CV/Gate outputs, 3.5mm sync in/out, and TRS sustain and expression inputs. The CV/Gate outputs can be mapped to velocity, aftertouch, mod wheel, or any other parameter, making the unit a practical bridge between a DAW setup and a Eurorack or semi-modular system. MIDI In is also passed to CV, so you can drive modular gear from an external keyboard routed through the KeyStep.
