You can input nested slurs, both during note input and by adding them to existing notes. You can also add nested slurs to existing notes on multiple staves at the same time and to notes in different voices or on different staves belonging to the same instrument; for example, when phrases span both staves of grand staff instruments.
Procedure
Result
During note input, slurs begin from the currently selected note on all staves across which the caret extends, not from the caret position. Slurs extend automatically as you input notes, and end on the currently selected note.
When adding slurs to existing notes, the selected notes are connected by slurs. For example, if you select two notes belonging to one instrument and two notes belonging to another, two slurs are input connecting the notes on each selected staff. If you selected notes on different staves belonging to the same instrument, a cross-staff slur is input.
Slurs are placed either above or below the notes, depending on the stem direction of the notes within the selection. Inner slurs can have different curvature directions to outer slurs. By default, Dorico Pro makes automatic adjustments to their positioning to avoid collisions.
You can input the outer slur and inner slurs in any order as Dorico Pro automatically adjusts slurs so that shorter slurs are positioned within longer slurs, and ensures they do not collide.
