I know little of the fruit type of computer, however there is a feature called Lead Sheet. Check it. I often print the sheet and have the scrolling. You can also change the number of bars that are scrolling so there are 5 or so.

If you are new to the tune, you can slow down the music by changing the bpm's until you are ok with the speed, or you slowly push it faster.
