Arturia Keystep Pro Polyphonic Sequencing Controller Keyboard

Advanced Polyphonic Sequencing Keyboard for Hardware and Software Control

The Arturia KeyStep Pro is a powerful sequencing controller keyboard designed to act as the central command hub for modern studios, live rigs, and hybrid hardware setups. Combining a 37-note velocity-sensitive keyboard with aftertouch, deep polyphonic sequencing, and extensive connectivity, it allows users to control synthesizers, drum machines, modular systems, and software instruments simultaneously. Whether sequencing analog gear via CV/Gate or controlling virtual instruments over USB and MIDI, the KeyStep Pro provides precise timing, flexible routing, and immediate hands-on control.

Four-Track Polyphonic Sequencer for Complex Arrangements

At the heart of the KeyStep Pro is a four-track polyphonic sequencer capable of recording chords, melodies, and automation per track. Each track supports independent sequence lengths, time divisions, swing settings, and playback modes, making it easy to build evolving arrangements that go far beyond simple loop-based sequencing. Polyphonic step input, real-time recording, and step editing allow users to craft detailed musical structures with clarity and control.

Dedicated Drum Sequencing with Performance Tools

In addition to melodic sequencing, the KeyStep Pro includes a dedicated 16-track drum sequencer designed for rhythm programming across hardware drum machines and software samplers. Each drum track can be individually muted, soloed, and edited, enabling dynamic performance changes during live sets. Integrated performance features such as roll, randomization, and pattern chaining make rhythmic experimentation fast and intuitive without disrupting workflow.

Deep Connectivity for Modular and External Gear

The KeyStep Pro excels as a hardware control center thanks to its extensive connectivity options. CV, Gate, and Mod outputs support modular and semi-modular synthesizers, while MIDI In, Out, and Thru ports ensure compatibility with classic and modern MIDI gear. USB connectivity allows seamless integration with DAWs and software instruments, making the controller equally effective in fully hardware-based or hybrid studio environments.

Expressive Keyboard with Aftertouch and Performance Controls

The 37-note slim-key keyboard offers velocity sensitivity and aftertouch for expressive playing and modulation control. Performance features such as scale modes, chord modes, and real-time transposition help keep performances musical and fluid while reducing wrong notes. An onboard metronome with visual feedback supports precise timing during recording and live performance, reinforcing the KeyStep Pro’s role as a reliable sequencing centerpiece.

Designed for Live Performance and Studio Precision

Built with a durable chassis and a clear LED-based interface, the KeyStep Pro is optimized for both stage use and studio sessions. Pattern memory, quick project recall, and synchronized transport controls ensure smooth transitions between songs or setups. Its ability to sequence multiple devices simultaneously makes it an ideal solution for musicians who rely on hardware instruments, modular systems, or DAW-based production without sacrificing flexibility.
