Overview

The Korg microKEY Air 37 is a compact MIDI controller built for musicians who value portability and a clutter-free workspace. Its Bluetooth Low Energy wireless connection lets you pair with compatible devices and play without a cable in sight, while the USB Type B port provides a reliable wired backup that also bus-powers the unit. The 37-key Natural Touch mini keyboard strikes a balance between a usable playing range and a footprint small enough to toss in a bag, measuring just 22.24 inches wide and weighing 2.21 pounds without batteries.

Beyond the keys themselves, the microKEY Air includes pitch bend and modulation wheels — controls that are often omitted on ultra-compact controllers but essential for expressive performance. A dedicated damper pedal input rounds out the control surface, allowing sustain functionality when connected to a compatible pedal. The unit is class-compliant, so setup is as simple as connecting and playing on supported operating systems. Whether you're producing on a laptop at a café or layering parts in a home studio, the microKEY Air delivers wireless flexibility without sacrificing the hands-on controls that matter.
