Arturia Keystep Pro Chroma

The Essentials to Know About the Arturia KeyStep Pro Sequencer-Keyboard

• True DAWless control center: 4 independent sequencing tracks, dedicated drum track, and built-in arpeggiator.


• Universal connectivity for hardware synths and modulars: 4 CV/Gate outputs, 8 Drum Gate outputs, 1 MIDI In, 2 MIDI Outs, and USB.


• Immediate creativity in live performance: looper, random playback modes, scale quantization, polyrhythm, and Chord mode.


• Stage ergonomics: 37 mini keys with per-note LEDs, 16 step buttons, 5 encoders, and bright OLED screen.

In the Lineage of Arturia's "Step" Series

The KeyStep Pro continues the legacy of Arturia's "Step" controllers by combining the compactness of a master keyboard with the sequencing power of a full command station. It bridges the gap between hybrid studio needs and live performance, catering equally to users of analog synths and Eurorack as well as modern MIDI setups.

For Whom and What Uses?

Ideal for keyboardists, producers, and performers wishing to control multiple instruments without a computer, the KeyStep Pro excels in DAWless workflows. It simultaneously orchestrates drum machines, mono or poly synths, CV modules, and MIDI expanders, while offering expressive playability thanks to Chord mode, user scales, and real-time controls.

Creativity and Real-Time Control

Designed for improvisation and stage use, it offers smooth step sequencing, real-time recording, note editing (pitch, velocity, gate, time shift, probability), and performance playback options. The looper, 7-mode arpeggiator, and random pattern playback spark instant inspiration, while scale quantization ensures pitch accuracy.

Compared to the Original KeyStep

The KeyStep Pro takes a leap forward with 4 independent tracks, a drum track with 24 rhythmic parts, polyrhythm, dual MIDI Out, 8 Drum Gate outputs, and LEDs above each key. The OLED screen and controller mode with 5 encoders and Control Change automation further expand studio control.
