Great product, works exactly how I need it to. I use it to control all of my synths. Managed to put the whole thing together pretty quick. I would consider it a beginner project, except it lacks in the documentation side of things. The instructions are quite vague and I feel there should be a diagram showing you what to do. I had to look at a picture of the finished project online to help me through it. The piece of paper with instructions I received did not mention if you get the USB powered version you need to solder pin 1 to pin 3 where there is an empty space. So if you get the usb power version make sure you do this! ;)
I decided to make it rack-mount, so I purchased a blank 1U panel and drilled holes, then mounted 5-pin midi connectors to the front and painted it. I hot-glued the PCB to the back of the panel and now it's quite a nice piece of kit. If you do this, keep in mind MIDI only uses 3 of the 5 pins, so don't bother wiring up all 5. I think just pins 2, 3 and 4 are necessary. With 3 being the shielded ground.
Using this to solve a common problem, syncing all my gear. Midi splitters are kind of expensive and often only 4 ports, so this 10 port splitter for not much dough is a great deal.
Putting it together is fun, but could use some documentation. As a first timer I found the bill of materials barely enough information to put it together. I would have appreciated some hand holding especially with identifying polarity of diodes.
This is a beginner project but does not have beginner guidance.
Overall happy with what I have. Figuring out a case for it is my next goal.
