Arturia KeyStep Pro Black Edition — Polyphonic Sequencing Controller

The Arturia KeyStep Pro Black Edition is a 37-key velocity-sensitive slim-key controller keyboard with aftertouch, built to sequence hardware synths, modular rigs, and software instruments from one desktop unit. Four polyphonic sequencer tracks and a 24-part drum sequencer replace a stack of separate devices in a hybrid rig.

What sets the Black Edition apart

The integrated metronome with a built-in piezo speaker and dedicated line output is rare on a sequencer at this tier, giving players a click track without extra gear. The 24-part drum sequencer supports polyrhythms via per-track lengths, while four CV/Gate/Mod outputs handle polyphonic Eurorack voice control from a single source.

Sequencer architecture and pattern workflow

Each of the four tracks stores 16 patterns, each pattern runs up to 64 steps, and every step can hold up to 16 notes for chord-style sequences. Patterns chain into songs and group into scenes for instant switching between sections of a live set.

• Sequencer Tracks: 4 independent polyphonic tracks plus a dedicated 24-part drum track on track 1
• Pattern Length: up to 64 steps per pattern with 16 notes of polyphony per step
• The arpeggiator features 7 modes and a 5-octave range assignable per track.

CV, MIDI, USB, and clock integration

The rear panel is the central hub of any hybrid setup: analog gear via 3.5 mm jacks, MIDI hardware via DIN, software via USB, all clocked from one master source.

• CV/Gate/Mod Outputs: 4 sets on 3.5 mm jacks for Eurorack voice control
• Drum Gate Outputs: 8 dedicated 3.5 mm triggers for modular drum modules
• MIDI: 1 MIDI IN, 2 MIDI OUT plus USB for DAW and softsynth control
• Clock I/O: Clock IN (3.5 mm TS), Clock OUT, Reset OUT for syncing external sequencers

Keys, controls, and physical build

The 37 slim keys carry per-key LEDs for live sequence visualization. Five rotary encoders, 16 step buttons, an OLED display, and dedicated pitch/mod/looper touch strips handle hands-on editing without menu diving.
