Flash Guitar Hero Game?

[Nig 13]

Hello, FlashKit!

So I am going to make this Guitar Hero game on Flash, but not with Arrow Keys. There will be notes appearing from the Right-Side and moving to the Left-Side, and you have to hit them with your Mouse/Cursor, which can only be moved on the Y-Axis - means I'm going to use hitTest

The problem is the Music! How to make the note slide from Right to Left, and how to make the Notes follow the music? I've tried using "Stream" and then listening to the Music and pausing, trying to make Notes whenever I want one that matches the music. But, how to make them slide from Right to Left and follow the music whenever they're on the same Y-Axis as the Cursor's Y-Axis?
