CME WIDI Jack + DIN-5 MIDI Cable Pack - Bluetooth MIDI Interface with 5-PIN DIN MIDI cables Included - Works with all DIN-5 MIDI devices - Wireless MIDI for Synth Keytar Pedalboard Keyboard

I preordered my first pair of WIDI Masters when they were still under development. They promised the ability to connect MIDI devices wirelessly without a third device, like a computer or tablet. It seemed too good to be true, but I was willing to try. I was not disappointed. I now own seven WIDI Masters and use them both live and in the studio. As a heavy MIDI user, they are amazingly useful tools. I keep finding more uses for them.This is one really important difference between WIDI Master and many of the other WIDI dongles you'll find here and elsewhere. Most of those others, such as the Yamaha MD-BT01, can NOT connect to other Bluetooth WIDI devices. They can only connect wirelessly to a computer, tablet or phone equipped with Bluetooth MIDI. In other words, you can't connect two such devices together. WIDI Master CAN wirelessly connect to almost any Bluetooth MIDI device, including other WIDI Masters. To put it simply, with two WIDI Masters you can connect any two MIDI devices (with 5-pin DIN connectors) wirelessly, without having to go through a third device. Essentially you use them just like MIDI cables--but without the cables! This is a really big deal. Nothing like this existed before WIDI Master. It's a game-changer.I've been using these little MIDI miracles in many ways. In my photo, you see three WIDI Masters plugged into my studio MIDI interface. I use these to connect (from left to right) a Korg nanoStudio controller, a Roland Aerophone Pro, and Roland SH-201 synthesizer. In my live rig, I use WIDI Master to connect two of my three keyboards directly to my iPad for changing patches via app (OnSong). I've even used WIDI Master to connect a set of Roland V-Drums to my studio from another part of the house. I could go on, but suffice to say these things have made a huge impact in my MIDI life. The things I'm using them for didn't even seem possible a few years ago. Now I don't know how I lived without them.Operating them can be remarkably simple, depending on your situation. In the most basic situation--for example, connecting two MIDI keyboards together--you simply plug them in. The devices will automatically connect to one another, and you're good to go. That simple. But things can get a bit complicated with more devices. With multiple Bluetooth MIDI devices in the area, managing which devices connect to one another can be confusing.Fortunately, CME has developed an app to control your WIDI Master setup. I highly recommend using the app to update the firmware on your WIDI Master before using it. You need to plug your WIDI Master in to power it (it gets power from the MIDI OUTPUT of any MIDI device). In the app, you'll see the device and be able to connect to it. Once you've updated the firmware, you'll have the ability to manage your settings. You can set a WIDI Master to "peripheral" mode. This prevents it from accepting connections while still allowing it to connect to other WIDI Masters. You can also create groups of devices that always connect in the way you need them to connect. These are incredibly useful features if you have many WIDI devices like me.To sum it all up, WIDI Master is an amazing little MIDI miracle that lets you connect almost any MIDI device to any other MIDI device wirelessly. It simply works, and works better than I'd thought possible. It's not an exaggeration to say these devices changed my life.

I use these many for hobby, but they are very fast - much faster than the delay from Bluetooth audio headphones. They are powered of the MIDI DIN connector (no external power needed) and can be configured like a wire, or series of wires via the WIDI app. There’s a bit of a learning curve needed, but they work well once set up. I have several of the now and the WIDI core all synced together.

Works great! Just not what I bought it for. Luckily, I have several MIDI devices to find another use for it.

I bought one of the bluetooth midi systems that are half the price and just couldn't get it working. To be fair, it was listed as a frequently returned item. I reeturned it and bought the WIDI. It paired easily and worked immediately. It was worth paying up for no frustration.

I got it to work with a Yamaha S80 keyboard connected to Mac OS 12, but only after a couple hours of fiddling. The S80 supplies bus power to MIDI OUT and, on first plugging in, the blue LED flashed slowly. Now the online CME documentation starts off by asking you to do a firmware update (via iOS). In hindsight I think this might be unnecessary for MacOS, but I followed the instruction and did the firmware update. After that, the Mac could not detect the presence of the WIDI Master even after I cleared the Mac's bluetooth cache, probably because WIDI Master was still paired with iOS. I finally had to turn off the iPhone and reset WIDI Master by pushing its reset button while unplugged, then plugging it back in while awkwardly holding the button. After some fiddling, I got it to pair with the Mac and show up as a MIDI bluetooth device in Audio MIDI Setup.I suspect I would have been better off never doing the firmware update and just pairing WIDI Master with MacOS out of the box. But that's not what the CME online documentation seems to say.Once I got it working, it seems to perform well, with low latency. Under Mac OS 12, I have to go to Audio MIDI Setup on every startup and reconnect to it. That's not a problem for me.

Infelizmente o produto não transmite wireless o sinal Midi do piano digital nem para IMac, nem iPhone e nem iPad. E não foi por não ter lido cuidadosamente as instruções e dicas da Web. Perdi meu dinheiro

Excelente, cumplió mis espectativas y es de un uso muy fácil, compré dos para poderlo conectar con un módulo KORG a un keytar Roland AX1 , solo descargue la app de la play atore en mi celular y los empareje vía Bluetooth

Magnifico invento para prescindir de los engorrosos cables. Funciona a la perfección y es fácil de configurar.

Had some issues to fit it in a Roland Sample pad!The contact on the side is in the way of the chassis

Works as described. Setup was as simple as plugging the device in. I bought two to use with a synth and midi sequencer and it's been flawless with no noticeable lag.
