Usb - midi host: my first arduino project

https://youtu.be/hyccEmUzZYw

Hey everyone! I've been trying to get into diy world for a while now. And finally I have something to share, it's a programmable usb-midi host device, you can watch the youtube walkthrough to get a feel of this device, also if you have any questions feel free to ask.

Note: this is my first arduino project and also this is my first c++ project so probably there's a lot of ugly stuff, though I've tried to keep it clean and clever :)

Nice project! I want to make the reverse of this: converting standard midi out to usbmidi out. I checked the sources of your project. But what is the actual scetch?
