The Widi Bud Pro worked flawlessly after performing the USB and Bluetooth firmware update. I recommend being very close to the Widi Bud Pro when updating the firmware with your phone. Roli is now instantly recognized the second I turn it on. I can't notice any sort of lag whatsoever It's almost as if the unit is plugged in via USB when it's not. Simply amazing! I finally found the solution I'm so happy! Review: Works great. - The device is exactly what you'd want for a point to point wireless MIDI connection base station. Used in a system with CME's WIDI-core remote module, it pairs reliably. Latency is as advertised (3mS) in any reasonable signal condition but seems to increase a bit right before you reach range limits. The overall range of the is not huge, but certainly adequate. A range improvement could be had using the CME WIDI-core module which uses an external Bluetooth antenna, if you have room for that (which I didn't). Bluetooth paring is always a sketchy business, but in normal operation this kit is as good as I've seen and will not be an issue. The only troubles I had were during the external firmware development process where I smacked it around in ways that would not be found in normal operation, so I don't count that against CME. CME handles the acquisition and loss of lock to the remote system well: it seems to provide "ALL NOTES OFF" on loss of lock and at first acquisition of lock. This is vital to avoid embarrassing stuck notes. All in all, very satisfied and will use CME's products in future projects. ## Features - [Get rid of those cables] Add Bluetooth MIDI to your MIDI devices and reduce the cable clutter in the studio.

I own both. I've found the WIDI Master to have a better range and stronger signal than the Yamaha unit. It can also do something the BT01 can't. You can connect two WIDI Masters together without the need for a computer or mobile device. Just plug and go. It's a fantastic product. **Q: Will this with qrs pianomation systems?** A: I hooked it up to a Pianomation system, but it is a little tight fit. Works good though. You have to hook up the midi out as WIDI Master gets its power from MIDI out. **Q: More than 2** A: Yes. With WIDI Group Connection and Group Auto-learn features, you can do 1-to-4 MIDI Thru/Split and 4-to-1 MIDI merge wirelessly. Please check cme-pro support page to get all instructions. **Q: Do I need two of these to connect two devices** A: Maybe. I use one of mine to connect to MainStage on my Mac and with this scenario, I only need one since the computer has Bluetooth.. Connecting two keyboards together requires two, one WIDI Master for each keyboard. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works flawlessly with Roli Piano (Lumi Keys) *by S***S on July 5, 2026* Windows 11's built in Bluetooth has weird quirks & limitations with Roli Piano (Lumi Keys) and most midi Bluetooth controllers.
