WIDI Jack
Wireless MIDI over Bluetooth
Get rid of those MIDI cables!

We have been working on wireless MIDI solutions for over 15 years...
Now you can add TRS MIDI, DIN-6-mini MIDI and DIN-5 MIDI to your wireless MIDI setup. You even can work with unpowered MIDI ports by utilising the USB-C power connector.
Simply replace your USB to MIDI cables. Connect to MacOS and iOS wirelessly with the versatile Bluetooth to MIDI technology.
And you can do much more: instrument-to-instrument and wireless MIDI groups are already available.
Bluetooth MIDI is just getting started...

What industry leaders say about us
I was lucky enough to be able to start working with a pair of prototype WIDI adapters from CME. They worked flawlessly and transparently. For example, I immediately had our flagship synthesizer, the Moog ONE, controlling and being controlled by our older MIDI instruments and vintage MIDI controllers.

CYRIL LANCE
CTO MOOG Music
CME WIDI is the first Bluetooth MIDI adapter that can perform as both a “peripheral” or “central” device, allowing fast, low-latency, and stable point-to-point wireless connections between any two devices.

TOM WHITE
Former President of MMA
I (Roger) have tested WIDI and found it to be well-designed, fast, easy to use and low-cost. Interestingly, CME have figured out how to get the latency down to as low as 3 ms, which is quite an accomplishment. In my test playing 3-note chords and melody with 3D MPE expression, I didn't perceive any added latency or delays normally associated with Bluetooth.
