Review: Works flawlessly with Roli Piano (Lumi Keys) - Windows 11's built in Bluetooth has weird quirks & limitations with Roli Piano (Lumi Keys) and most midi Bluetooth controllers. 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: GREAT Product that made my life much better! - I use these to control program changes with my Kemper Rack using an Android phone and Band Helper app. I have MIDI commands associated with each song. When a song is selected in the set list, the correct patch and settings are setup automatically (and wirelessly) on my Kemper. I have them plugged into the back of an SKB roto molded 3 space case with my Kemper and the distance is great. I have been up to 50 feet away without any problem (that's as big a stage as I am likely to ever play on anyway :) ). These were easy to setup and get working. Worked great on my Android tablet. I do have to pair it every time through Band Helper (once a power up), but it has been rock solid (not drops, no misses). Well worth the money.

## Questions & Answers

**Q: Will this work the same as a Yamaha md-bt01?**
A: Yes, but much better.  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.

### ⭐⭐⭐⭐⭐ A real life saver
*by Z***. on December 11, 2023*

I am using this with: Windows PC Android Tablet Meta Quest 3 and Quest 2 VR headset (PianoVision app) -I have a Kawai digital piano and did not want to run a USB cable around to my devices. However, I had trouble connecting my piano's Bluetooth to anything other than official Kawai apps. Windows requires 3rd party hacks for Bluetooth MIDI and they do NOT work well. -This device saves me the headache on everything. I had some troubles updating the firmware but eventually got it squared away. Once I had set the device up, it's SUPER easy. Just plug it into any device, the piano immediately connects with no noticeable latency, and it stays connected. It bypasses your devices bluetooth stack all together which is great, because many android apps don't support bluetooth midi. Please note - when I move my receiver 8 ft from my piano it starts to cut out notes. This is most likely a limitation on my piano's bluetooth transmission power, but something to keep in mind. I highly recommend this product. I would have given up on using my keyboard's bluetooth midi if i hadn't found this device.
