Manufacturer description

The Korg MicroKEY Air 37 puts a full three-octave playing surface on a controller small enough to live beside a laptop. Its 37 natural-touch mini keys are velocity-sensitive, and KORG pairs them with both a pitch wheel and a mod wheel — a combination most compact controllers drop to save space, and the reason this board handles expressive synth leads rather than just note entry. Connection is your choice: Bluetooth MIDI for cable-free playing, or bus-powered USB when you want zero latency and no batteries to think about. Because the MicroKEY Air is class-compliant, it registers as a MIDI…

KORG's audio & midi lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Does the Korg MicroKEY Air 37 need drivers?

No. It is class-compliant, so macOS, Windows, and iOS recognize it as a MIDI device on connection with no driver install required.

Can I use it wirelessly with an iPad?

Yes. The MicroKEY Air connects over Bluetooth MIDI, which is what the Air designation refers to, and it is class-compliant with iOS. Confirm your specific app supports Bluetooth MIDI input.

Does it need a power adapter or batteries for USB use?

Not for USB. The keyboard is bus-powered, drawing what it needs from the USB connection. For wireless Bluetooth operation, check the product listing for the current power requirement.

Can I connect a sustain pedal?

Yes. The MicroKEY Air 37 has a damper pedal input on the rear for a standard sustain pedal, sold separately.

How many octaves do 37 keys cover, and is that enough?

37 keys is exactly three octaves, with octave-shift buttons extending the usable range. That is enough for two-handed parts, bass plus lead, and most synth work - more than a 25-key controller gives you.
