Review: Trouble-free and cable-free MIDI connection - I've used this in a CME setup with macOS, iOS, and Raspberry Pi, and it's always reliable, and no noticeable latency. Wireless MIDI is fun, especially if you're playing a keytar!
Review: What a great gizmo! - Got the CME WIDI Thru6 yesterday. Connected it to my two midi enabled devices (Line6 HX Stomp and a BeatBuddy) with the short CME midi cables I also ordered. Paired via bluetooth to my iPad and it just worked! No messing around; no fiddling with what cable goes where. Simple and effective and just what I'd hope for. After downloading the WIDI App and connecting via that, the WIDI Thru6 went through a pretty quick firmware update - this meant I had to reconnect the Bluetooth but, other than that, all is good.

## 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.

### ⭐⭐⭐⭐⭐ What a great gizmo!
*by J***K on 10 October 2024*

Got the CME WIDI Thru6 yesterday. Connected it to my two midi enabled devices (Line6 HX Stomp and a BeatBuddy) with the short CME midi cables I also ordered. Paired via bluetooth to my iPad and it just worked! No messing around; no fiddling with what cable goes where. Simple and effective and just what I'd hope for.

### ⭐⭐⭐⭐ Brilliant but don't expect to update easily with Android!
*by R***Y on 26 September 2025*

Used on an Alesis Vortex Wireless 2 as the built in wireless is unreliable. 2 x widi masters required for tx and rx. Expensive but brilliant range and reliability. The cons. Forget updating it using Android easily. Two devices failed to even see them. The third newer device simply would not connect consistently coming up with a message to clear the Bluetooth cache and try again. The fix is to hold the button whilst inserting into the midi out port until the unit flashed green, then red. At that point the device is detected by the app as being in update mode. You can manually select the widi master device and update the firmware. It still won't detect in the app in normal operating mode but the update completes, the units pair and then you're away with reliable, very low latency widi. Highly recommended if you can get past the hard work that I had to figure out for myself. I hope this helps some folk. Rob.
