CME U6MIDI Pro - MIDI interface with router and filter - plug-and-play USB MIDI for computer - 3-in-3-out MIDI with Merge. Split, Thru

An excellent device that works perfectly on Linux. I have 4 single-channel synths and a drum machine along with an ancient power-hungry multi-timbral Roland D-110 (from 1989). The issue is that I rarely use the D-110, so it needed to be daisy-chained at the end of all the other MIDI devices so it could be left switched off. But daisy-chaining 6 devices (with more to come) is not a great idea for latency, etc. U6MIDI Pro to the rescue! With the software you can download from the website, you can select which USB inputs go to which MIDI outputs, which means that rarely used devices can be kept on their own MIDI ‘circuit‘. Within your DAW, select output “U6MIDI Pro MIDI #” (where “#” is either 1, 2 or 3) and an appropriate MIDI channel and you’re away. Or, if you don’t need more than 16 MIDI channels, just use “U6MIDI Pro MIDI 1” for everything, but use the channel routing feature of the U6MIDI Pro to send particular channels to particular MIDI outputs. This is more than a multi-in multi-out MIDI device though. Within the software, for each USB or MIDI input you can filter out MIDI channels and message types that don’t make sense for those MIDI devices, and you can do some fancy message manipulation stuff that I’m not sure I’ll ever need. The software runs well on Linux, which is a bonus, and like most class-compliant USB devices on Linux these days, doesn’t need any extra drivers. Overall I’m really impressed by what it can do, how easy it is to set up, and compatibility with various OSs. Would definitely recommend.

Fantastic small MIDI interface with 3 inputs and 3 outputs. Plug and play on macOS, immediately usable from Ableton. Connects conveniently to computer via USB-C. Solved a sync issue I was having with an Access Virus TI2 connected via USB - connected via MIDI the timing sounds very accurate and together. The included UxMIDI software is excellent. Full filtering and routing of MIDI messages between the ports! It is very configurable. The only slight downside is that the 3 in ports are on one side of the device and the 3 out ports are on the other side. That means if you have a cable that pairs together 2 MIDI ports on each end (e.g. MIDI in/out) you have to have it stretch the cable over the device to plug one end into each side.

Needed to disable start MIDI messages to some devices while leaving it enabled for others. This little MIDI router/filter worked perfectly for the job, the software interface works well and was very easy to configure for what I needed and worked first time. Hasn't introduced any noticable latency although I'm constantly fiddling with Ableton latency settings so this could be different for others. Great price compared to a lot of other MIDI filter options out there but retains a good build quality. Would recommend as a good little MIDI utility box that just gets the job done with very little fuss.

I’ve used a couple of event processor plus’s for years and they are great, but when it’s time to program them, it can be a bit of a pain, especially if you haven’t done it for a while. This CME unit works flawlessly, and the software is very easy to understand, allowing you to program complex set ups in a few seconds. Minutes at most. If I use it plugged into my MacBook Pro it powers no problem, but so far I haven’t managed to get it to power passively from anything else and have had to use an iPhone charger to power it via it’s USB-C port. At this point, I’ve used it with a Nord Wave 2, a Moog Subsequent 37 and a Ampero II Stage effects processor and none of them have powered it. But that’s the only downside I have found. I don’t use a computer on stage, so I will just have to run another cable to it. A very useful feature is to be able to see which inputs are routed to which outputs via the blinking LED’s on the top of the unit. Well worth the money!

I had a few problems to solve 1) I now have 2 controllers on my pedalboard so I needed some kind of merge 2) I needed USB MIDI from my computer 3) one of my MIDI devices corrupts the chain back to the others (my old CME MIDI hub sorted this. With this magic box I have in/out 1 to controller 1 in/out 2 to controller 2 and out 3 to a chain of effects with the rogue one at the end. All works flawlessly. However I assumed everything would be connected to everything internally. Not so. No routing is set up. You have to download the CME software, preferably first do a firmware update, then choose to connect the various ins to outs with the simple point and click tool. Dead easy.

An excellent little unit at a good price. Does exactly what I need, connecting via USB to my PC DAW and via 5 pin DIN to a controller keyboard and some external MIDI expanders. Easy to configure split and merge using the free UxMIDITools software. I will confess that I had some problems, but CME tech support is very good, responsive, helpful and patient. The connection problems I had are most likely caused by my USB hub, but I am hopeful the problems have now been resolved. I also have a U2MIDIPro (USB to 1-in 1-out DIN) which is also very good.

I absolutely love this thing I haven't used more than 3 midi connections on it yet but from my usage so far this feels really well made and thought out. The app for controlling it works great on both Windows and Linux. Seems like they put a lot of effort in for both the hardware and software for this. As a beginner to MIDI I'm seriously impressed

I needed to sincronize the midi from my dawless setup. Worked really good. Just in a few minutes i could configure mi digitakt as the main device, sending midi(DT MIDI - OUT) orders to all the other devices (digitone, microfreak, keystep). In addition, the app for macOS is really intuitive. Only need a few clics and everything is configured as you need.

Funktioniert super. Das Routing lässt sich sehr leicht mit der App einstellen.

Klinkt allemaal mooi...maar compatibiliteit is een gokje. Ik had er iig veel moeite mee. Jammer want 3 ins en outs zijn natuurlijk voor deze prijs mooi. Ook functies in speciale software zijn meestal een red flag. Mijn oude vertrouwde edirol um one weer gepakt. Hassle free. Wel maar één in/out. Dat dan weer wel. Probeer het zelf. Get Lucky.

I always had Creative Labs Sound Blaster cards around that had MIDI connections, and after my last computer upgrade MIDI connections were no longer possible - not to mention laptops are more standard now. Picked this up to connect to my Casio Digital Piano to help with recording. It's super easy to setup - just plug everything together, open the software, and things just work. I use Linux and previously had some issues doing the setup so expected more of a hassle but this was so simple i was recording within minutes of connecting everything up and plugging it into my laptop.

Funciona perfecto en computadoras Apple, sin necesidad de instalar drivers, y es sencillo configurar los distintos modos que tiene para operar, si tuviera el doble de puertos (6 en lugar de 3) sería mucho mejor
