Wireless MIDI Made Easy

CME consider themselves the wireless MIDI expert since 2005, with their WIDI (Wireless MIDI) technology already serving thousands of professional musicians worldwide. They tell us that after they launched the Xkey Air (2015) and the WIDI BUD (2016) they’ve received many requests about advanced MIDI connectivity over Bluetooth. The result is their wireless MIDI over Bluetooth adapter: WIDI Master. This is what they have to say about it…

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 www.cme-pro.com
