Beyond Bluetooth MIDI controllers: The WIDI Family

Wireless MIDI over Bluetooth
Low Latency Wireless MIDI

CME and the future of wireless MIDI

Today there are many musicians and producers that use a bluetooth MIDI controller. Ever since the introduction of the UFv2, CME has been in the game of innovating wireless MIDI solution. After the introduction of the portable Xkey and its successor the wireless Xkey Air, we received many requests for improving the connectivity of MIDI over Bluetooth.

WIDI delivers more than a Bluetooth MIDI controller

That is why we have been working on an entire new range of MIDI over Bluetooth adapters. With over 15 years of experience it is now possible to innovate alongside the technological developments of Bluetooth. With the arrival of Bluetooth 4.0 BLE it is now possible to transmit MIDI over Bluetooth with ultra low latency. Therewith the time has come to make MIDI over Bluetooth as effective as your traditional MIDI cables. It is time to get rid of those wires.

I’ve been spreading the word about the WIDI Master on different forums. I am excited. I may purchase a couple of units at the same time. Do I get a discount for each unit? Quote from registrant as provided by email
