Cross-staff and cross-voice slurs
Cross-staff slurs start on one staff and end on another staff, and cross-voice slurs start in one voice and end in another voice.
Dorico Pro positions cross-staff and cross-voice slurs in the same way as it positions standard slurs. You can move and lengthen/shorten cross-staff and cross-voice slurs in the same ways as standard slurs; however, they do not behave in the same way. For example, you cannot move cross-voice slurs to notes on the same staff in other voices, and you cannot lengthen cross-voice slurs to notes on the same staff in other voices. You also cannot lengthen/shorten cross-voice slurs to notes in different voices to those in which the slur started/ended.
You can only move and lengthen/shorten cross-staff slurs to notes on the same staff as the corresponding endpoint. For example, if a cross-staff slur covers a phrase that starts on the bottom staff and ends on the upper staff, you can only shorten the cross-staff slur to the first note on the upper staff, you cannot shorten it to any notes on the bottom staff.
The different voices can be on the same staff, or on different staves.
By default, Dorico Pro adjusts cross-staff slurs to avoid collisions. You can change the collision avoidance of cross-staff slurs in the Avoiding Collisions section of the Slurs page in .
