Overview

The Korg microKEY Air 25 is designed for musicians who want to break free from cable-tethered setups without giving up tactile key input. Its headline feature is Bluetooth MIDI connectivity, which lets you place the controller on a couch, bed, or café table and wirelessly send note data to your DAW or mobile music app. Pairing is straightforward on macOS and iOS thanks to native Bluetooth MIDI support, and the controller is class-compliant, so no driver installation is needed. A USB 2.0 port is also included for traditional wired operation, which doubles as bus power so you can save battery life when working at a desk.

The 25 velocity-sensitive mini keys are built on Korg's Natural Touch keybed, which provides reasonable resistance and expression for a controller in this size class. A single pitch/mod joystick sits to the left of the keybed, combining pitch bend and modulation control into one compact input. At 0.67 kg, the microKEY Air 25 is light enough to carry in a laptop bag alongside a computer or tablet, making it a practical choice for producers who compose on the go. It ships with license keys for select Korg software, giving new users a starting point for sound design and production without an additional software purchase.
