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.
