CME introduces WIDI Master – Wireless MIDI over Bluetooth adapter

CME has been the wireless MIDI expert since 2005. Our WIDI (Wireless MIDI) technology already serves thousands of professional musicians worldwide. After we launched the Xkey Air (2015) and the WIDI BUD 92016) we’ve received many requests about advanced MIDI connectivity over Bluetooth. We present to you today our wireless MIDI over Bluetooth adapter: WIDI Master

With WIDI Master you can connect all your MIDI devices without wires. No matter if they are master or slave. For instance, you can connect two standalone MIDI hardware devices. Also you can pair your Bluetooth MIDI controller with any standalone MIDI instrument.

Furthermore you can pair your standalone MIDI hardware (switch to slave mode) with any iOS device or Mac. In addition, for Windows and Android users, you can use our WIDI BUD to fully enjoy the benefit of wireless MIDI over Bluetooth.

WIDI Master automatically pairs with any Bluetooth MIDI device. It offers ultra low latency by directly embedding the BLE MIDI protocol in its firmware. With our customised antenna design and automatic panic mode WIDI Master delivers the most reliable wireless MIDI connection

Our goal is to get 1,000 supporters to start production. We ensure the best price and limit our waste. We only manufacture what is really needed. And deliver it directly from our factory to your doorstep. Currently the price point is set at $39 instead of $59. To receive this discount and WIDI updates you have to register on
