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.
