Does anyone use the built-in score display on their arrangers? Yamaha, Korg, and Roland all have this feature. I personally struggle to turn the pages of longer scores without falling behind or making a mistake.

I've tried using the score display on a Yamaha PSR and concluded that the screen is a little too small for read-ahead. That's a shame because the Yammies have a slick feature where you can load a song in RAM and sync it to the arranger-based accompaniment. I know the Tyros have a bigger screen, as does the Korg Pa900.

One more question... is there a PC software that does the same thing? I've heard of the MusicPad Pro but that still required a foot pedal to advance. I'm looking for a software that scrolls through the notes and chords of a MIDI file while the song plays in real time, in a "follow the bouncing ball" visual format.

Would love to hear your collective experience with this type of electronic aid.
