One way that the Music Animation Machine score doesn't correspond to the experience of hearing music is that it doesn't emphasize the importance of the "now" moment. When you are listening to music, what you are hearing at the present moment is much more present, more tangible, more real, than what has come before or what you're anticipating. In the M.A.M. score, the present, past, and future are given much more equal weight; the "now" moment is indicated only by its central position on the screen and the highlighting of presently-sounding notes.
A possible variation of the display that would emphasize the "now" would look like this:
This looks kinda cool, but the disadvantages are many:
The last of these disadvantages has been the main reason I haven't experimented with this beyond the pen-and-paper stage.
