To get the Twelfth golden egg star, the soundboard, you need to recreate the beginning of the song that is playing on the golden egg level screen. For the musically challenged among you, it is Blue, Red, Black (with eyes closed), Blue, Green. It should then complete the rest of the song for you and, voila, the 12th star.
