Just read the stuff up! Mess with the demo! Backpack stuff if you want! Use it or lose it buddy! Example of use for something like this: a chase game where when the chaser gets closer to the player, the main instruments of the song get louder and while they are away only like... I dunno the bass plays or something Example 2: A round based game where before the rounds, the music is chiller and vise versa Example 3: A game where different enemies are associated with different instruments, and those instruments are removed when they are defeated, so you can know what enemies are in play if you know what instrument they are associated with
