MIDI Keyboard for Bluetooth Applications

The Xkey Air 37 from ESI is a Bluetooth MIDI keyboard that could hardly be any flatter or more compact. The 37-key keyboard is velocity-sensitive and even features polyphonic aftertouch for more expressive playing. The keyboard can be paired wirelessly with Macs, iPhones, iPads and any device with Bluetooth 4.0. The USB port not only charges the internal battery – which ensures up to 10 hours of mobility within the reception range – but also provides a wired option for using the Xkey Air 37 in a stationary setup. Thanks to Class Compliant, the controller is recognised immediately without the need to install any drivers. With the free Xkey Plus app, you can easily configure the Xkey Air 37 to suit your own needs and, if required, assign a different MIDI command to each key, for example.
