When you think of music, Xkey is there for you.
It is an elegant work of art. It’s also a fine instrument that follows you wherever you go. The black and white keys are supported by a cool silver color aluminum panel arching down at the front and a holder hidden at the rear bottom. These silky smooth keys intertwined with the aluminum grille. It presents a beautiful picture that the keys are like floating evenly at the edge of a waterfall.

Ultra Slim
The body of the Xkey is housed into a piece of molded aluminum. The thickness is merely .62″ Weighing at a little under 1 lb, the Xkey is even lighter than the iPad. With the slim and light form factor of the Xkey, it can be completely put into standard size backpack. Xkey not only inherited the essence of the piano keyboard, also succeeded beyond the limits of traditional music keyboard design that with the rugged and lightweight mobile features perfectly together.

Professional Standard Keys
The key layout of Xkey follows exactly octave range of traditional piano in accordance with professional keyboard player’s finger memories and playing habits. Aluminum grille is used to clearly separate each key in order to ensure that the player can locate key positions while playing blindly on the keyboard. The structure of each individual key is designed in such a way that the entire key moves down at the same level when it is pressed at any part on the key. Such design gives unified sense of touch to the player.

Ultra Sensitivity
Under each key and button, there is a customized pressure sensor connects to the intelligent circuit board with high-processing power. The intelligent circuit board produces details of the performances at very low power consumption. Such details including the 128-step full range of velocity intensity and the corresponding polyphonic after-touch control, up to 16,000-step pitch-bend control, and real-time response speed manipulation.

Full Review: CME XKey Air and CME WIDI BUD

choirguy | techinmusiced.com

The XKey Air is incredible. It isn’t a piano (key travel is 1/8 of an inch or so), but for people needing a quality keyboard interface for notation or digital audio workstations–this might very well be the answer. It looks and feels like an Apple product and should be on shelves in the Apple Store.

The WIDI BUD has blown my mind–it can convert nearly any device without Bluetooth Low Energy to a BLE MIDI device: Windows, Android, Mac OS, iOS, Linux, and yes, CHROMEBOOK. And it doesn’t just work with the XKey Air, it will work with any Bluetooth MIDI device (JamStik+, PUC+, mi.1, c.24, etc.).

Go wireless with the Xkey Air MIDI keyboard: a review

Philip Rothman | Scoring Notes

If you’re on the road a lot, going totally wireless is appealing, and is well worth the premium. But even if you’re at a desktop most of the time like I am, having one fewer cable reduces the clutter in a surprisingly meaningful way. Now my three main input devices — computer keyboard, trackball, and MIDI keyboard — are all wireless for the first time. And, as has been the case with the previous two Xkey keyboards that I’ve reviewed, the Xkey Air has earned a permanent spot on my desk.
