CME MIDI Thru5 WC - Premium 1-to-5 MIDI Thru - High-precision 1-in-5-out wired transmission with high-speed optocoupler for error-free synchronization of all MIDI devices via 5-pin DIN

This replaced my Quadra-Thru because I needed that extra 5th port. I don't know if the power supply was necessary but since I had additional power supplies available, I've been using it while supplying power to it. It distributes my midi clock from my beatbuddy to 3 loopers, a delay pedal, and a microkorg. Works as expected and fits nicely on the pedal board.

I have multiple MIDI devices that I had daisy chained and was getting stuck notes. This simplified the entire setup and solved that problem. I use it with the CME 3 IN /3 OUT box to have flexibility without having to switch cords around. Both require a power source but work nicely off of a USB hub. Build quality is great.

I've been learning how to use MIDI for a while now, and ran up against the inevitable wall of learning that you can not just daisy chain each keyboards or synthesizers MIDI Out port to the next ones IN, and have your messages from the source device continue past the first destination.For that you need a MIDI Thru output, and many modern synthesizers have opted to not include one (though lots let you configure your Out port to act as a Thru instead).Pretty simple to build cheaply if you are handy with a soldering iron and can find a schematic, but it looks like prices are beginning to lower on premade options since I last checked, (was around $60-$70 I think) and it seems much more worth it to me than it used to.This is a neat little device that solved all of my MIDI routing to my hardware synths and controllers. You just insert the controlling devices MIDI Out port to the Thru boxes MIDI In, and you can broadcast the signal to 5 other devices at once. If you need more ports but already have one of these, you can easily daisy chain one of the Thru out ports to the In port of another box for 5 more connections.There is a way to upgrade the box to handle MIDI over Bluetooth, but I haven't tried that yet. Hardware cables are your best bet for lowest latency, but it is nice to have the option.

Works great with no data transmission lost at a great price.

I have had no issues with MIDI messaging while using this thru box. It comes in a small space saving design. It is powered with USB C. The casing is made of hardened plastic. It seems to be sturdy. It's not thin and cheap. I have another MIDI thru box that has a metal casing. It's not quite that tough, but it can probably take the rigors of the road or just chill in the studio just the same.It may be small in size, but it has 5 thru/out ports and 1 MIDI in port. Each port is 5-DIN compatible. It can be used with other MIDI devices too if you need some extra ports. This can be used with pedals, controllers, synthesizers, and pretty much anything with MIDI capabilities.There is also a WIDI option. I have never used that function, so I cannot attest to its veracity. My studio works on cable connections, so I'm not using that tech currently.Overall, I think it's a great device. It's good for professionals and beginners alike. MIDI is such a great technology, and this device will help take advantage of it's capabilities. It would be great if this could be a thru box and a merger box, but that would probably make it a little less affordable. If you are merely looking for thru/out midi, then you can't go wrong with this one.

Saw others posting similar for much much more and gave this a chance instead. Using it in between an Arturia Keystep 37 and several Korg Volcas, pretty easy to set up, from someone doing synths & midi for the first time.The package deal with 4 cords was nice, but had to buy 2 more, for all 6 ports.As my collection grows, I most likely have to buy another.

Worked great right out of the box. Is solved my technical problem right away. I recommend this.

Does the job
