With a fully marked up score you can take advantage of additional features.
When tapping on the Scroll mode button in the lower toolbar you have now additional options:
Tap on the button in the lower toolbar first and then tap on the bar in the score you want to jump to. The cursor is then placed at the beginning of the selected bar. This also works while playing. The metronome or audio playback will always follow the cursor.
You can practice a section of the score by setting loop points.
With the fully marked up score you can also use the quick navigation feature ( in the bottom toolbar) to jump to specific staves or bars.
