Hi Mogge,
The Xkey Air used new Bluetooth MIDI standard which is proposed by Apple and accept by MIDI association recently, so until now only macOS, iOS and Android 6.0 have native driver in the system, Windows did not release their native driver yet. If you want to use it on Windows, please use our WIDI BUD (www.widibud.com), we implement the Bluetooth MIDI protocol in the dongle so that you can connect with Xkey Air via Bluetooth.dwe
