well, that's the only way of doing it if you listen to the sophistication of the total arrangements, which come out like multitrack midi files and you will be hard pressed to produce the total effect without a control track on some songs. You could copy the song to a blank disk and edit the control track to delete all panel memory, pad, techni-chord and sustain etc data and leave just the score in the screen. After all once you've learnt the song you can play it anyway you like
