Raven is Forte with a few extra bars. and if you need those extra bars you can update forte. but the beautiful thing about LUI is its modular nature. you can run raven if you want, someone else can run forte if they want and i can use neither as i like :D
We'll sing all night, and drink all day, And on the girls we'll spend our pay, And when it's gone, then we'll away, To dance with Jak o' the Shadows.
