Extracting Musical Parts from Full Scores

You can extract a musical part from a full score.

Prerequisite

You have prepared the score, including all formatting, inserting project layer block text for the score title, setting the barline type, etc.

Select the tracks from which you want to extract the music, and open them in the Score Editor.

The order of the tracks only matters for the spacing of the staves in the layout.
Select Scores > Settings.
Open the Layout tab.
In the Layout Name field, enter a name for the full score.
Close the Score Editor.
Select a single track, and open it in the Score Editor.

The project layer settings are automatically shown in the new single-track layout.
Prepare a layout for the single track.

You might for example move barlines, add endings, activate multiple rests, etc.
In the Layout Name field, enter a name for the new layout.
Click Apply.
