RS232 to Midi module

For MIDI RS232 Interface with USB and DIN5 1x1 I/O

I tested it and this interface works perfectly, I use it with the Voyetra 64 sequencer (MS-DOS), I recommend this seller.

I love this module!

For Fidget Spinner Eurorack LFO Oscillator SpinnerLFO

Very very cool electromechanical instrument. It outputs up to about 1V of bipolar CV, depending on how hard you spin. This is enough, even without amplification, for things like vibrato effects, e.g. plug into a VCOs linear or exponential FM for different flavors. Also works as an audio source for low frequency rumble. Shipping was so fast, it felt like it arrived before I ordered. Very easy to assemble, I just wish there were some minimal instructions like where the washers go and which cable goes to which connector. But easy enough to figure out myself. Thanks for making these!

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.
