Control, unplugged Too many wires in your studio? Are they literally holding you back from the freedom of different configurations and setups? KORG, creators of the best-selling microKEY series and the next-gen microKEY2 series can help you break free with the new microKEY Air series of wireless MIDI controllers! Oh, and with an average of one hour of use per day, the batteries allow approximately one month of operation. And best of all, the microKEY Air runs on just two AA batteries! Connect wirelessly to iPad, iPhone, Mac, or Windows The microKEY Air supports Bluetooth Smart “Apple Bluetooth Low Energy MIDI”. You can easily connect wirelessly to iPad/iPhone music apps such as KORG Gadget, KORG Module, and GarageBand, as well as any MIDI-capable music production software on your Mac or Windows. Painstaking tuning of the Bluetooth capabilities means high stability and low latency, no strings – or wires – attached. Compact and playable Natural Touch Mini Keyboard KORG’s Natural Touch mini keyboard has been carefully designed to assure playability while staying compact, and makes it easy to play chords or rapid phrases. Choose between 25, 37, 49 or 61-key configurations to suit your specific playing style and space/travel requirements. Connect a pedal, and enjoy full control functionality The 37, 49, and 61-key models provide an assignable switch jack for connecting a damper pedal. The 25-key model provides a sustain button that implements the damper function. On all models, you can use the octave buttons in conjunction with the key transpose function to play MIDI's entire range of notes. The 37, 49, and 61-key models provide pitch bend and modulation wheels. Bluetooth MIDI Connect for Mac The dedicated utility "Bluetooth MIDI Connect for Mac" allows fast and simple wireless connection between your Mac and KORG Bluetooth enabled keyboard (such as the nanoSTUDIO series and microKEY Air). Bluetooth MIDI Connect for iOS "Bluetooth MIDI Connect" allows you to wirelessly connect your iPhone/iPad and KORG Bluetooth enabled keyboard (such as the nanoSTUDIO series and microKEY Air) even when using an app that does not support Bluetooth MIDI. This enables wireless connection for any app that supports Core MIDI.
