Combining powerful sequencing abilities with a 37-key, velocity-sensitive keybed with aftertouch, the Arturia KeyStep Pro may be the controller and sequencer you’ve been waiting for. Equipped with USB for use with your software instruments, MIDI for your hardware synths, and CV/Gate/Mod outputs for Eurorack modular synthesizers, there is little the KeyStep Pro cannot control. And with its four-track polyphonic sequencer, dedicated 16-track drum sequencer, and advanced functions like randomization, arpeggiation, and chord modes, it’s clear the KeyStep Pro is definitely not your average keyboard controller. Whether you perform electronic music on stage, or have a wide range of gear in need of a comprehensive controller, you’ll be impressed with the Arturia KeyStep Pro controller and sequencer.

Comprehensive controller and sequencer for modern producers

The Arturia KeyStep Pro keyboard controller gives you a ton of creative potential, and you’ll find yourself turning to your computer and mouse less and less. Four tracks of polyphonic step sequencing allow you to compose chord progressions and melodies right from your instrument, while the dedicated 16-track drum sequencer handles rhythm duties. You can adjust tempo and swing directly from the KeyStep Pro, and there’s even a built-in metronome with a speaker — that means you can improvise and experiment without messing with the click track in your DAW. In other words, the KeyStep Pro is a master controller that handles more like a dedicated instrument.

Ditch your DAW on stage

If you perform electronic music on stage, you know the apprehensive feeling when you’re setting up your DAW for stage performance. The KeyStep Pro may allow you to ditch your DAW on stage entirely, especially with its solo metronome output — you can send that to your drummer for use as a click track. You have the ability to inject randomness in your sequences for sonic variety, adding a ton of interest to sequences that may otherwise sound repetitive. And when it comes to playing parts in real time, the KeyStep Pro feels responsive and expressive.

Masterful control over your hardware collection

Even if you rarely use a DAW for production, the Arturia KeyStep Pro is a smart way to tie your hardware collection together. On top of dual MIDI outputs for synthesizers, drum machines, and MIDI-equipped effects, the KeyStep Pro is well-equipped for Eurorack and semi-modular synthesizers. In addition to its configurable outputs for CV (with support for polyphonic CV operation), Gate, Mod, and Clock Reset signals, you also have eight dedicated drum gate outputs to control multiple modules easily. So no matter what combination of hardware (and software) you’re using, We are sure you can customize the Arturia KeyStep Pro to operate however you need it to.
