The melodies.txt/practice mini game thing is killin me!

I know there have been multiple posts on how to alter the txt or whatever but i still don’t get it. Can’t you just alter the percentage of each musician on the game xml? Or can somebody copy and paste an altered melodies.txt file to make it easier? I’m stuck, it’s too hard and my band is goin down the drain :frowning:
Help please! Xoxoxo!
