CME WIDI Jack - Bluetooth MIDI Interface for TRS/DIN MIDI Devices - Power by MIDI Out or USB-c - Ultra Low 3ms Latency Wireless MIDI for Synthesizer EWI Keytar Pedalboard Digital Piano

What a cool little dongle. I used this to add a wireless footswitch to my Boss RC-500 Loop Station and it works excellently. The connectivity is fast and consistent, and it runs off of most midi devices internal power meaning it doesn't need it's own supply though it does have a USB-C jack for this purpose if needed, making it compatible with older gear that may not have modern midi specs. The included cables are just what i needed, though their short length might not suit all applications. Make sure you choose the correct package with the proper cables for your setup. Totally worth it for the convenience it provides in not having to run more cables to an already crowded floorspace.

So far this product has been great for me, and has been working exactly as I hoped. Its been pretty much plug and play with no troubleshooting for me. Haven't noticed any sort of delay. However I don't really use this with a bunch of blue tooth midi so not sure if it has drawbacks there, I usually just have two devices connected - a synth or sampler connected to a Bluetooth midi controller. I have also been able to connect it with my ipad (using korg gadget app) and it has worked to sync clock and midi input. - pros - given you have compatible devices, is pretty much plug and play. haven't had a issue connecting yet. - can be externally powered via usb c or powered by the midi out from your device. - not locked down to a specific midi cable type given you have the adapters. - works with A and B midi - has a built in magnet and comes with a separate sticky magnet so you can mount it on your devices if you have the room. cons- - the female jacks on the unit are NOT 3.5mm TRS and for some reason they are 2.5mm TRS. Not the end of the world but strange to me since 3.5mm is (in my experience) way more common plus I already owned a plethora of 3.5mm cables and 3.5mm to midi cables. It also seems strange that they picked this because the size difference between the two isn't that big. This information was also pretty buried on the store page so that came as a surprise when I received it. I want to think there was a valid reason for this, but it stinks of a strategy to get you to buy their cables. - the blinking status light is kind of bright and distracting, especially if you are transmitting a clock over midi ( it blinks on midi input and blinks repeatedly clock sync). When I am just goofing around with my sampler and controller at my desk I literally hide the widi jack underneath something or else the blinking light kind of drives me crazy because its surprisingly bright and piercing.

Wireless MIDI that works well

Why did you pick this product vs others?: Super tiny. If you can't find a place for this on your pedalboard you might have a problem :). It's easy to set up. If you don't use it for a while you will need to reconnect the bluetooth via the WIDI app but other than that it's been maintenance free. I use it with the free MIDI PAD App on my iPhone and iPad to jump quickly between presets on some Line6 gear I use. It's a great tool if you want to use simple MIDI from a mobile device or laptop.

Works great

Works perfect to add Bluetooth to non-Bluetooth Morningstar controllers (or other MIDI devices). Using this to connect my MC6 Pro to my iPad. Allows me many functions, including using the Morningstar editor over Bluetooth, as well as page turning capabilities in other apps.

I'm not used to blutooth devices being this usable. Especially when they aren't from the same company. My use case, I needed to make an XKey 37 Air work with a Polyend Tracker+. For one, make sure you get the one with TRS cables. I ordered the one with 1/8 inch midi cables. I needed 1/4 TRS Roland style, to work with the Type-B input on the Tracker+. They do offer both. Just don't mess up like I did. Thankfully they sell the cables I did need for ten bucks in a pack of two, so I didn't end up having to buy a complete kit twice. In the meantime, I have a disgusting 5 adapter kludge making it work. Second, if you are just using it to receive midi from a device and output it to something, you'll need to power it with something. It takes power from the midi output. I can't give up my midi output on the Polyend Tracker+ to power it. And there's a very important reason I can't so I'm going to share it. If you are like me, and you are trying to make an external blutooth keyboard work with the Polyend Tracker, or Tracker+, and you try to use both the input and output so you can power a Widi Jack without using another usb-c cable, you'll end up spending another 70 dollars on a CME Midi Master box with built in blutooth, so you can then reconnect your tracker to the rest of your midi gear. At that point you will figure out that your blutooth keyboard, that only had ONE thing it could connect to, will try connecting to your fancy new midi/widi hub and tracker at the same time. CONSTANTLY. And it will put you in a situation where you are constantly fixing this nonsense by unplugging things in order, and plugging them back in an order, so it works right. For a few hours. Until it gets messed up again. yeah. Just source some USB-C Power, and power the WIDI Jack with it, and save 70 bucks and torture. Keep it simpler. So..... I needed external usb-c power. Thankfully I had no issues finding a spare USB-C cable. My surge suppressor has some 3amp USB-A style sockets, so I used a USB-A to USB-C cable to provide it power. Then my XKey 37 Air connected almost immediately. If you wait a minute it will always connect. If you are impatient, disconnect the power to the Widi Jack, then reconnect the USB-C, and it will connect almost immediately. What this gives me, is the ability to keep a really decent 37 key velocity and polyphonic aftertouch sensitive keyboard nearby, all charged up, that will always be able to talk to my Polyend Tracker+. That I can point at one of five midi destinations. Currently a Bree6, A Trigon 6, a Typhon, a TR-08, and a Pro-800 that is about to be replaced by an Artemis. And it's heaven. This is my dream rapid song creation platform, and this tiny little piece makes it all possible.

Works perfectly!!!

Bin sehr zufrieden damit. Habe es bisher nur in der Wohnung verwendet um ein IPad mit einem Multieffektpedal zu verbinden. Bisher schnelle und stabile Verbindung ohne Unterbrechung.

Ho acquistato diversi prodotti CME e fanno tutti il proprio dovere. Connessione stabile, latenza praticamente impercettibile. Prodotti per uso professionale

簡単に、一度接続すると、後の接続は自動でやってくれます。

Well, it works - I have Android 13 and Win 11 - But you have to use the WIDI app and some reboots and an USB charger to get this thing updated and working. The idea is excellent but as always, with beta software it takes some time to get all things working :-)

After trying cheaper options that were literally useless as they couldn’t play back midi data in time, i tried this & it works flawlessly. There is latency obviously but it’s extremely low and constant so you can adjust the rest of your hardware accordingly.
