Thanks a lot for your review :D, I'm glad you're enjoying it and that you were interested in how the game works.
I agree that the note generation could be improved, particularly when you aren't experienced with choosing the best settings like I am, I would definitely like to create a tutorial when you first open the game explaining the science behind it.
Besides that, I have been pondering on ways I could improve the
note generation and have some ideas which i will try when i get the time.
