Just Plug & Play:

We created WIDI BUD to enable you to easily play and perform music on your setup without wires. The WIDI BUD is a class compliant Low Energy Bluetooth adapter which has been optimized for low latency MIDI music connection. The WIDI BUD will connect with nearly any Bluetooth MIDI device and is compatible with Windows, Mac, iOS, Android, Linux, and google chromebook devices. The WIDI BUD was made for the Xkey Air 25 and the Xkey Air 37, but it will work on nearly all Bluetooth MIDI devices such as the Korg microKEY Air, nanoKEY studio, Jamstik+, Yamaha MD-BT01/UD-BT-01, Roland A-01, and more.

Low Latency:

Special minimized latency Bluetooth technology eliminates time lag. Many devices that come with Bluetooth may be outdated and slow, but the WIDI BUD is designed to have minimal latency specifically for playing music. This is possible due to the specialized software inside the dongle’s firmware using the latest Bluetooth. Most prepackaged Bluetooth replies on drivers which are depended on the hard drive and increase lag.


No need to worry about drivers, language settings, 32 or 64 bit issues or slow hard drives. WIDI BUD just plugs into your USB port and it’s ready to go. The WIDI BUD even works great on phones due to the Low Energy Bluetooth that reduces battery drain. see product specifications for full list of compatible operating systems. You’re not limited to connecting our own Xkey Air. The WIDI BUD dongle plays nicely with all other Bluetooth MIDI devices, including the Korg microKEY Air, nanoKEY studio, Jamstik+, Yamaha MD-BT01/UD-BT-01, Roland A-01, etc.

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.
