Featuring a velocity-sensitive 37-note Slimkey keyboard with aftertouch, it delivers expressive control in a space-saving format ideal for studio production, modular setups, and live performances. Pitch and modulation touch strips provide intuitive real-time control, while chord and scale modes make it easy to explore harmonies and stay in key. Whether controlling DAWs, virtual instruments, or analog gear, KeyStep 37 mk2 offers precise, hands-on playability. At its core, KeyStep 37 mk2 is a creative sequencing powerhouse built to inspire new musical ideas. Its polyphonic step sequencer supports up to 64 steps with 8-note polyphony, while the 16-mode arpeggiator offers dynamic pattern generation. Advanced tools like Mutate, Spice, and Dice allow users to transform sequences instantly, creating evolving melodies and rhythms on the fly. Pattern chaining, overdubbing, and automation recording for pitch bend and modulation enable deep creative expression, while four dedicated encoders provide direct control over sequencing, arpeggiation, and assignable MIDI or CV parameters. Designed for maximum connectivity, KeyStep 37 mk2 integrates seamlessly with modern and vintage setups alike. It features USB-C MIDI, full-size MIDI DIN In/Out, sync I/O, sustain pedal input, and four configurable CV/Gate outputs including Pitch, Gate, Mod 1, and Mod 2 for modular and analog control.
