description Arturia KeyStep Pro Overview
The Arturia KeyStep Pro is a unique hybrid controller that focuses on sequencing and performance. It features a 4-track polyphonic sequencer, making it the heart of any modular or hardware-heavy setup. The keys are slim but highly responsive, and the touch strips for pitch and modulation offer a modern feel. It is not a traditional DAW controller, but rather a performance instrument that allows you to control multiple synths simultaneously.
For those who perform live or want to move away from the computer screen, this is an essential piece of gear.
