I am struggling mixing my beats. Like on i been writing down taking notes on other peoples beat.
Need help with the arrange ment. or are there fl studio templetes kind of like I set mine up that will help better.
Like when do the hats comes in or drums come in or when they drop. Take a look at the beat I made!
