Arturia KeyStep 37

Rounding out the lineup of Arturia's compact Keystep series with convenient connections and clever sequencing, the KeyStep 37 expands on the capabilities of its predecessors while still closely maintaining the small form factor of the original. On the surface, the KeyStep 37 would just look like the original KeyStep with five extra keys and a BPM display, but Arturia has gone the extra mile to add in some cool new features and provide some quality of life enhancements.

Perhaps the biggest functionality added to the KeyStep 37 is the enhanced Chord mode. Twelve different chord types are available at the press of a single key, making it easy to construct harmonic progressions on the fly. Where things get interesting is the incorporation of a strumming mechanic, that at its most basic level functions like a one-shot arpeggiator, but the flexibility of specifying note spacing, timing between notes, and velocity sensitivity through the strum allow the quick development of complex yet organic compositions. Any instrument suddenly becomes dynamic and controllable in the same way as stringed instruments like a guitar or harp. KeyStep 37 also features a handy scale mode, which quantizes played notes to the nearest note in a specified scale or key, minimizing accidentals when undesirable and keeping the music flowing.

While KeyStep 37 bears the most resemblance to the original, some ideas introduced on the KeyStep Pro have carried over to this model. Namely, a row of handy RGB LEDs live above the keys that signify notes being played back from sequences and arpeggiations. Similarly to the KeyStep Pro, the KeyStep 37 also features four encoders which may be mapped to four banks of MIDI CCs, meaning that 16 parameters are available within quick reach.

Like the other members of its family, the KeyStep 37 provides plenty of connectivity options for use with nearly any combination of hardware and software. KeyStep 37 is small but mighty, packing in more features and flexibility than many controllers costing several times its price.
