Length of arpeggio signs

Dorico automatically adjusts the length of arpeggio signs when the pitches of the notes in the voices to which the sign applies change, or when you add notes to the chords or delete notes from the chords.

You can change how far arpeggio signs extend beyond the outer notes in all chords project-wide on the Arpeggio Signs page in Engrave > Engraving Options. You can set different values for when notes are on staff lines and in staff spaces.

You can also lengthen/shorten individual arpeggio signs.
