Even more interesting if it allows variations in the same soundtrack according to different dramatic moments in the same scenarios. Example: a man is walking down the street vs a man is walking alone in the night down the street vs a man is walking alone in the night down the street unaware of a bright red dot on his back. All these scenarios could use the same soundtrack, but require different dramatic levels. The game would send data to the music algorithms so that the soundtrack would reflect the right mood.

Contrast with this very human representation of writing gameplay musical scores. Including the simple chart used to show segued clips.
