WIDI Master 

Premium Bluetooth MIDI

Get rid of those MIDI cables!

We have been working on wireless MIDI solutions for over 15 years...

Finally, you can replace your USB to MIDI cable with Bluetooth to MIDI solutions.

Of course you can do much more: instrument-to-instrument and wireless MIDI groups are already available.

And Bluetooth MIDI technology keeps evolving...

What is WIDI Master?

WIDI Master is your virtual MIDI cable.
Bluetooth MIDI is the new wireless standard as approved by the MIDI Association.

Now you can connect all your MIDI devices - without cables - even without computers - with MIDI over Bluetooth!

Smart Connectivity Algorithms

WIDI distinguishes itself from any other Bluetooth MIDI technology available through its unique SCA technology. SCA is a collection of highly effective algorithms that optimise the performance of WIDI in any given situation. SCA stands for Dual Role Automation, Automatic Pairing Mode, Smart Hub Functionality, Latency Reduction Optimisation and Range Performance Optimisation!

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.

Moog Music

CYRIL LANCE

CTO MOOG Music

CME WIDI Master 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.

MMA

TOM WHITE

Former President of MMA

I (Roger) have tested WIDI Master 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.
