Bring movement to your melodies and animate your chord patterns with 8 arp modes, including 3 vibrant new random modes, switchable in an instant. Use the hold function to allow your arpeggios to play freely while you tweak and refine. Embellish with extra notes and layer up to 4 octaves above or below for a lively, dynamic sound.

As with the sequencer, you can adjust swing, gate time and tempo subdivision while your arpeggios are playing. Finally, the LED strip above the keyboard also displays triggered arpeggios in real-time, so you’ll never lose your place.


A sequencer that listens, learns and responds to your style of playing. Experiment with intuitive step-sequencing or live recording, complete with ties and rests, and hear them back instantly. Append your sequence with extra notes, or replace/overdub notes at any point.

There’s 64 steps at your disposal, with 8-note polyphony per step. Save up to 8 sequences and switch between them on the fly. Change swing, gate time and tempo subdivision, even during playback. Your sequenced notes are shown on the colourful LED strip above the keyboard - sequencing has never been this easy.

Chord mode

Transform a single-note melody into a chord sequence at the touch of a button. Use the 4 new controls to choose from 12 chord voicings, including a user-defined chord, for distinct harmonic flavours.

Energize your voicings with time-based strum effects, select the number of notes per chord and adjust velocity sensitivity - the harder you hit, the more notes you’ll hear.

MIDI CC control

Use the expanded control panel to interact with your MIDI hardware and software in real-time. Tweak up to 16 assignable MIDI CC parameters across 4 switchable colour-coded banks.

Easily assign your own CC values to each bank using the panel itself, or via the free MIDI Control Center software. Personalise the way KeyStep 37 communicates with your desktop synths, modular gear and VST instruments

Scale mode

However you choose to explore with KeyStep 37, you’ll never go out of key.

Activate scale mode to quantize any notes you play to a scale of your choice. Choose from chromatic (default), major, minor, blues, or a user-defined scale. Use with the sequencer or arpeggiator to freely sketch, compose or improvise ideas in perfect harmony.
