KeyStep 37 goes beyond an easy-to-use 64-step sequencer, arpeggiator and MIDI keyboard. It's responsive, dynamic, expanded in every direction to encourage musical exploration - the controller that’s built to inspire.

More is more

The familiar KeyStep formula, expanded. KeyStep 37 features a velocity-sensitive 37-note keybed, complete with aftertouch and RGB LED feedback, while remaining lightweight and compact.

At the center of the control panel, you'll find 4 new knobs with an LED screen, giving you instant access to inspiring new expressive tools and MIDI tweaking - total creative control.

Music made interactive

The new controls unlock KeyStep 37’s unique & enhanced Chord mode. Choose from 12 chord types, an array of strum effects, and spread the voices out into complex velocity-sensitive parts that respond like a stringed instrument.

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.

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.
