The Xkey Air 37 from CME 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 Mac, iPhone, iPad and all devices with Bluetooth 4.0. The USB port not only charges the internal battery, which provides up to 10 hours of mobility within the reception range, but also offers a wired option for using the Xkey Air 37 in a stationary position. Thanks to Class Compliant, the controller is recognised immediately without the need to install drivers. With the free Xkey Plus app, you can easily configure the Xkey Air 37 to suit your needs and, if required, assign a different MIDI command to each key, for example.
