So, there's two things I wanna talk about.

Learn to compose (or even learn Music theory, or become a better sight reader).

Convert midi into sheet music.

There's a FREE tool that allows you to make a professional (no paper wasting) music score by midi or self writing it.  Back then, I used this a lot. It taught me a lot about writing music on actual music sheet.

Musecore.com is the website where you may download it.  So, if you ever wanted to play live, but need to hire a few musicians to play the extra instruments, well here you go with this.  Start productivily write music scores or convert midi into a music score.

I hope this makes thing fun for you! <:
