Arturia KeyStep Pro Sequencer

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, it 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.
