Was a simple kit to build, and I'm far from an expert. One of the optocouplers ended up being bad, but that could have been my fault. I had spares on hand, so no problem. Love the design, very elegant!
I put this together without too much drama. but i do have electronics experience - Other reviewers have stated trouble with component identification and orientation. I was familiar with these issues and just had to double check - anyway, I plugged it in and it worked 1st time - didnt have to troubleshoot. So I now have to think about what sort of enclosure I want to put it in. Cheers to Deft audio.
The kit is easy to assemble and the instructions are clear. With a minimum experience in electronic assemblies it is completed successfully. It works perfectly and exceeds my performance expectations. Excellent
This MIDI Thru 1in4 does the job well. I'm not a musician so I can't comment on fidelity, or on longevity, but it works for me just great and don't notice any flaws. The build itself was easy. I appreciate that and it's very low cost, making it easily attainable on a budget.
I have a beatstep pro as a master to the MIDI 1in4, then 4 Thru to 4 other Arturia gear, with sequencers, and a TD-03. I set sync to midi on all devices except the BSP (Int), which allows me to start/stop all other devices, but still control each device's sounds independently. Or change sync and control most everything from the BSP. The 1in4 made this all very easy. I was nervous at first, because I had read of a few issues with getting things synced, but I had no issues and I'm pretty stupid when it comes to music, much less MIDI (I get the gist lol).
Board ist ok. I modified the Board to comply to the Midi Standard and to be more robust. Used the Board to build my own Midi Interface with Midi merge and several routing options. I added some 5V Open drain Output Logic drivers because to Connect the Controller Pins directly to the connector ist not a good Idea. Added also some components for better EMI. The input optocouplers are not the fastest there are better newer replacements. Added a pull down to the Base of the 2nd Darlington Transistor for faster switching.
This MIDI breakout is awesome. Its basic functionality with the provided sketch is what most people would need. With some expansion and minor tweaks, you can make it do a whole lot more! This is not a consumer product; you must know how to program an Arduino or Teensy to make it useful to you. But that makes it way more fun! Shipped with a faulty optoisolator, but the seller was quick to make things right.

Great Unit!!! But jack barrel input is center positive
