Connecting your musical ideas

KeyStep 37 goes beyond an easy-to-use sequencer and arpeggiator.

Record, perform, and experiment with a compact, accessible keybed that’s familiar and enjoyable in equal measure. Push the boundaries of your expression with real-time MIDI CC control and LED feedback. Unlock undiscovered creative potential with the inspiring and unique Chord and Scale functions.

KeyStep 37 isn’t just a keyboard controller - it’s your new source of inspiration.

Enhanced playability

The same velocity-sensitive 37-note keybed as the KeyStep Pro, complete with aftertouch and RGB LED feedback. A lightweight and compact keyboard that offers full and familiar creative flexibility, whatever your style or ability.

At the center of KeyStep 37’s interface we’ve added 4 new control knobs with a screen, giving you instant access to inspiring new expressive tools and MIDI tweaking - total control.

Music made interactive

KeyStep 37’s unique & enhanced Chord mode takes your single note melodies and unfinished ideas and transforms them into musical stepping stones. Choose from multiple voicings, instrument-like strum effects, and velocity settings and make your music really sing.

Map out KeyStep 37’s 3-octave keyboard range with a scale of your choice using Scale mode. Any key you play will automatically quantize to the nearest note in the chosen scale - never play a wrong note again.

Tap into the inner workings of your MIDI hardware and software with assignable 16 MIDI CC parameters across 4 switchable banks. Use the 4 new controls to tweak settings on the fly for dynamic performances.

The core of your setup

KeyStep 37 is designed to be put in control. An accessible interface, a compact design and comprehensive connectivity make it the perfect centerpiece for your rig - whatever your needs.

Hook up your synth hardware with MIDI in/out. Control your favorite VST instruments with MIDI over USB. Use CV pitch, gate and mod connections for modular integration. Analog sync in/out keeps everything in time without hassle. The best bit? Use it all at the same time.

Connection is key

Connectivity has always been at the core of the Step range. KeyStep 37 is no exception - command every aspect of your setup with ease.
