CME WIDI Master - Wireless MIDI Bluetooth Adapter - Ultra Low Latency, MIDI Split Merge - Synthesizer to Digital Piano, macOS, iOS, Android, Win

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!

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.

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.

Great product from a Great company. The first order was delivered to the wrong address, and they promptly sent a new one. The WIDI adapter has a good, solid wireless MIDI connection and very low latency. I've used Yamaha, Quicco Sound, and WIDI beats them both.

Very happy with this bit of kit. Have it hooked up to a fairly old Yamaha electric Piano (YDP 140). I was concerned when ordering that it may not work, but it works perfectly. I use it to link my Piano to my Ipad, where I can play through GarageBand and various other apps, with not noticable latency at all. Make sure you read the instructions, this does need a seperate free app downloading to work, and does not work with the default Bluetooth connectivity in the iPad. But once the App is running it works seamlessly with all apps tried so far. Bit pricey, but well worth it!

I've been using bluetooth midi to send midi from a Widi Master to my M1 Mac. All worked great but, often, I could notice some delays and note dropped notes (especially when playing fast parts). I read this is because MacOS does not prioritize bluetooth midi processing (among the many processes the computer is running). So, I got this Widi Uhost to handle the bluetooth midi to USB conversion instead. This means that, to my Mac M1, it's like if I had a usb midi cable plugged to it. It works great! It paired with my Widi Master (make sure the Widi master is set to "peripheral") and no more delays or dropped notes. As always, fast delivery from Amazon!

A little tricky to set up, but CME provided first class support and it was well worth the effort. The unit performs extremely well and provides all the expected functionality. I highly recommend it.

Don't bother if you have windows 11. It will sometimes connect, but mostly not. You need to mess around with Korg drivers to even start trying to get it to work.
