Many thanks, I must have missed something in the manual. it's an age thing !!
Gerry,

With a song loaded (and your tablet in landscape mode), tap the center of the screen to bring up the overlay. At the top left of the overlay is a circle - tap it. This will bring up the popup menu. Tap the autoscroll button to start the auto-scrolling. You can also tap the Scroll Settings button to change how often the screen scrolls.

Regards,
Mike
