Showing accidentals in parentheses
You can show individual accidentals in parentheses, and also hide/show accidentals individually. For example, you can show an accidental in parentheses on subsequent notes in tie chains that cross system/frame breaks.
Procedure
Result
Accidentals on the selected notes are shown, hidden, or shown in parentheses.
Note
If you are hiding/showing many accidentals, it might be easier to change the accidental duration rule for the project.
