The Arturia KeyStep 37 mk2 is a compact 37‑note Slimkey controller and sequencer that blends classic Arturia ergonomics with upgraded generative tools, extensive CV/Gate outputs and deep DAW integration. Design & Playability The 37‑note Slimkey keyboard delivers velocity‑sensitive keys with after‑touch, allowing expressive performance in a small footprint. Two capacitive touch strips provide real‑time pitch‑bend and modulation, while built‑in chord and scale modes generate harmonic ideas instantly. Sequencing & Generative Tools A polyphonic step sequencer supports up to 64 steps and eight‑voice polyphony, feeding a 16‑mode arpeggiator that produces evolving patterns. The Mutate, Spice and Dice utilities inject variation on‑the‑fly, letting users reshape riffs, alter octaves, modify note lengths, insert silences and record bend and wheel automation without leaving the instrument. Control Interface Four dedicated encoders sit beside a clickable OLED display, granting immediate hands‑on control over arpeggiator, sequencer and Mutate parameters. Each encoder doubles as a programmable MIDI CC, while a separate control button expands assignable functions across all modes. Connectivity The unit offers USB‑C class‑compliant MIDI, traditional MIDI DIN In/Out, 3.5 mm sync I/O and a sustain/expression pedal input. Four CV outputs – Pitch, Gate, Mod 1 and the newly added Mod 2 – map to velocity, after‑touch, mod‑wheel and other sources, enabling precise control of modular rigs and hardware synths. Software Bundle Arturia supplies Analog Lab Intro, providing over 500 sounds, together with Ableton Live Lite for immediate production capability. Physical Specs The main unit measures 547 × 148 × 43 mm and weighs 1.09 kg; the gift box dimensions are 596 × 178 × 78 mm at 1.6 kg. Power draws from USB‑C or the supplied USB‑A to USB‑C cable, and a Kensington lock slot secures the device on‑stage. Why Choose Arturia KeyStep 37 mk2 Seamless blend of classic tactile feel and modern generative sequencing Four CV outputs give unprecedented modular control from a compact controller Dedicated encoders and OLED feedback streamline live performance adjustments Built‑in chord, scale and arpeggiator tools accelerate creative workflow Includes Analog Lab Intro and Ableton Live Lite for instant sound design
