Just what I needed

For Eurorack MIDI TRS Thru 1in -> 4out midithru

This is exactly what I was looking for. I send midi from the Oxi One into it and can mult out from there with A or B to other modules and even other synths.

Great kit, all parts are there, but overzealous taping

For Teensy 4.1 MIDI Breakout board 8in / 8out USB host

Updating my review, since I finished the build, and it works perfectly! I use PlatformIO as my dev environment, not the Arduino IDE, which didn't work at first. To fix that, all I had to do to was add #include <EEPROM.h> at the top of the .ino file with the other includes and build_flags = -D USB_MIDI to platformio.ini. The PCB is excellent, and the instructions are clear. Labeling and orientation of components on the PCB itself is great. It's so straightforward that instructions aren't really needed if you know what you're doing and you pay attention: For example, the orientation of the 6N138 IC's isn't as obvious from the board, but I could make it out from the photos, and I could find it on the schematic like I should have anyway. Word of advice though: Go easier on the packing tape or use something different. The tape was strong enough to rip all the bubble wrap and the plastic bag containing the MIDI jacks.

Most powerful MIDI hub I ever had; great communication

For Teensy 4.1 MIDI Breakout board 8in / 8out USB host

I'm very glad I bought this kit since it obsoletes at least three other pieces of MIDI gear in my setup. Seller Deftaudio was very helpful and quick to respond.

Firmware is available on GitHub and could be tailored to my needs easily. (8x8 MIDI merge - comes out of the box. USB MIDI interface: There's a firmware for that too. Filtering certain MIDI messages, transposing notes ... all possible with a little bit of coding.)

To compile the firmware, I had to select "USB Type: Serial + MIDI" in the "Tools" menu of the Arduino IDE.

If you don't mind a bit of soldering and have maybe a little bit of experience using the Teensy, I can't think of a better device than this.

Missing components in the kit.

For 9V Power Converter Adapter for guitar pedals, MIDI

I purchased this unique power supply kit and the midi 4 to 1 splitter kit. I like the design and thought behind the products these guys sell. The aesthetics are pleasing. Keeping the costs down like this is super awesome! From purchase, until I had the products in hand was 14 days total. I spent the evening putting them both together. Documentation is sparse, but the PCBs are labeled well and the builds are fairly straight forward. Basic electronics knowledge is a pre-requisite, but even a novice with some soldering skills should be able to complete these fairly easily. I will need to find a way to enclose these properly for my application as they will need some level of water resistance.

However, the power supply kit was missing 2 components. A 470ohm resistor, and a 100uF inductor. So, the project is on hold until I can source the inductor. :-(

Very sorry to hear that. It might be much easier to contact us for any missing parts that we can ship you some extra or refund.

Good for beginners

For Eurorack USB-C and USB-B Power Supply

I'm sure it's good for non-beginners as well. This was an easy way for me to get started with Eurorack
