Hello everyone, before I start I would like to apologize for using the translator for the question because I am not good at English.
Please, has anyone managed to make this project work?
I saw it on the internet, I managed to compile and load it on the arduino uno, but I can't send midi messages from my computer to the arduino board via usb. Thanks.

No you won't be able to do this without some sort of software on the computer to do this. You can write your own in any language, a popular one is called Processing. Or you could get a DAW ( Digital Audio Workbench ) that can send MIDI out to the Arduino.
The author listed the tools he used in the README.
You can either use Hairless MIDI, a tool on your computer to create a virtual MIDI port and connect to the Arduino using the standard serial firmware, or you can flash custom MIDI over USB firmware like USBMidiKlik.

Saw that list but you don't actually generate MIDI with Hairless, it just generates a virtual MIDI connection. Te OP needs something to generate MIDI messages.
