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.

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.

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.
