It just works.
Not cheap, but it works. Set up was not plug and play, but the online help documentation and app went through all the steps in detail and a few minutes later I had perfect 2 way midi between my keyboard and Mac. Running a cable around the room would have pushed USB to the limit. No latency, so very happy.

Excellent,works great
Fantastic, I've a MacBook with no Bluetooth midi so I've decided to try this out . I've also used a widi jack plus which connects to my instrument via midi in /out . I can have my instrument at one side of the room now without the need for extra long cables. Played around with this now for about 2 hours and works great . Simple to set up and just select the Widi bud in whatever software/ saw you're using and it pairs automatically. Very pleased

Great little device.
Worked straight out of the packaging, no setup! Brilliant. Undetectable latency in live playing, much better than expected. Pricey, but worth it.

Brilliant but don't expect to update easily with Android!
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.

Highly recommend,! Very impressed with both the Widi Uhost and the CME company that manufactures it!
I purchased the CME Widi Uhost to allow my Boss Katana 100 Mk II amp to connect to the Boss Katana Librarian in addition to the Tone Studio which I was already using. The unit arrived timely and is a great design being small and compact and instruections were easy to use to set it up. It paired with my iPhone 14 via thier Widi Uhost app when connected to the Katana with a USB B to USB C cable and powered using my iPhone's charger. However, after downloading the Librairian it would not connect to the amp after updating the unit's USB and Firmware to v0.2.2.4 so I contacted CME who were extremely helpful and adivsed to downgrade to the previous v0.2.2.1 which worked perfectly. CME's developers will now find the issue and release a fix in due course. I would highly recommned this unit to anyone needing to connect to their Katana 50 or 100 Mk II as well as using the device for any Midi keyboards etc. 5 Stars CME

Great idea, poorly designed.
The connector cable socket is badly positioned. The little cable connector can't be inserted into the Widi because of the angle of the socket which puts it physically too close to the power adapter of my Fractal FM3. This means it cannot be connected and is therefore useless. I returned it and went with the Yamaha MD BT01 which works flawlessly.

Very happy with this gadget!
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!

Wireless Midi? Go on then!
Wireless Bluetooth on a digital kit surrounded by wires may seem like a funny option, but one of my soundcards doesn't have MIDI. Anyway this took a little while to sort out because my Macbook is on High Sierra and for some reason it wouldn't find it in the Audio MIDI Setup tool.I sucessfully paired this with my other machine running Catalina so I knew it wasn't a failed unit. I then downloaded the app from the Apple Store and connected to the device. I upgraded the firmware on it to the newer firmware, which still didn't work, so I reflashed it with the older one. For some reason this worked and I was then able to connect using the Apple Audio MIDI Setup tool. You have to go to the Bluetooth section in order to see it and connect.Once connected it was so, so simple to hook into Ableton and I was up and running in no time. One thing is that if you don't use it, it will go to sleep and you have to re-connect in the MIDI Setup tool, so just add this to the finder bar and you'll have easier access next time.Latency is really good! I couldn't really feel anything too untoward, and it's really opened up this drum kit to more options using Komplete, Battery, Contact and of course Ableton's Drum Rack/Sample triggering...Make sure you download the manual and watch a few of their tutorial videos on YouTube. They're really simple but get you up and running...

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!

Excellent product - but make sure you install them correctly
These Widi links are a marvel, allowing me to connect a stone-age but wonderful Yamaha keyboard to the latest and greatest computer equipment. I did however have an issue installing them - my iPad would not recognise them. There was excellent and immediate support from the manufacturer and from the Facebook user group so I was able to identify the problem quickly - good support is rare these days so I think the manufacturer should be praised for doing good support. The issue turned out to be a) firmware needed to be updated and b) all other bluetooth profiles must be deleted before installation ( in my case it was an Apple Pencil causing the problem). So you must delete all existing bluetooth connections, then install and run a firmware update on the WIDI, and then re-install the other bluetooth profiles on top. Everything now works and is of high quality. Recommended.

Merveilleux
Acheté pour établir une connexion MIDI entre mon clavier (piano digital) Panasonic SXKC211, qui date de l’an 2000, et ma tablette Galaxy A9 Plus. Fonctionne comme un charme. Pour l’installer sans problème, toutefois, il faut suivre les instructions á la lettre. Notamment, ouvrir, fermer le Bluetooth et réouvrir le Bluetooth à certains moments précis est absolument nécessaire. Malheureusement, mon objectif consistait à utiliser la connexion avec Flowkey mais ce programme, qui reconnaît les connexions MIDI BLUETOOTH lorsqu’on utilise un produit Apple, ne les reconnaît pas encore avec les tablettes Andoïd. J’ai quand même décidé de conserver le MIDI Master en espérant une mise à jour prochaine de Flowkey. D’autres applications reconnaissent la connexion et c’est tellement bien de ne pas avoir de fils qui traînent par terre, De plus, la connexion fonctionne parfaitement, ce qui n’était pas le cas, avecs les fils que j’avais achetés précédemment.

Çok hızlı
Hem hızlı bağlantı kurdum hem de gecikme yok denecek kadar az. Ipad pro 11 2021 sadece tek usb c portu var. Hub almaktansa kulaklık adaptörü aldım. Midi klavyemi de midi master ile bluetooth ile ipad e bağladım. Hiç zorlanmadım hemen çalıştı. Cubasis uygulaması hemen algıladı. Yani ihtiyacımı kablosuz giderdim.
