By default, Dorico Pro automatically adjusts the shape and position of slurs to avoid collisions with items under their arc.
This means that if a notehead under a slur is either higher than the others under a slur curving upwards, or lower than the others under a slur curving downwards, the curvature of the slur is adjusted to avoid the collision and keep the notehead under the slur. You can disable collision avoidance for individual slurs and all slurs project-wide.
In
, you can change how slurs are adjusted to avoid collisions, such as choosing a balance between changing the shape of slurs to compensate or moving the endpoints of a slur, and how asymmetrical slurs are allowed to be.Collision avoidance for cross-staff slurs
You can activate/deactivate collision avoidance for cross-staff slurs in Dorico Pro to use the point at which notes cross to the other staff to determine the curvature of cross-staff slurs, which produces better shapes in most cases.
. When cross-staff slur collision avoidance is activated, you can allow/disallow-
Due to the increased complexity in positioning slurs across staves, further manual adjustment in Engrave mode might be required.
-
These settings do not apply to S-shaped slurs between staves, which do not have any collision avoidance.
Slurs bisecting accidentals
According to conventions in published music, slurs can bisect the stems of flat accidentals, but not sharps or naturals, to save vertical space.
You can allow/disallow slurs to bisect different accidentals, and alter the maximum amount of accidentals’ stems that can protrude through slurs, on the Slurs page in Engraving Options.
