Five Lines can handle songbooks that contain multiple songs in a single PDF file.
After you have imported the song book in the app, it will initially appear as a single song. You can then split the songbook into sections by marking the start and end of each individual song.
After you have created all sections, you can navigate between them by tapping on Basic Settings in the top toolbar and selecting the desired section.
After you have selected a section, all staff markers except for the current section are removed and will be ignored when playing the song.
If you choose All as the current section, the staff markers of all sections are displayed again.So to add additional sections you always have to select All as the current section.
You can delete a section by tapping on besides the Sections setting.
