Slurs automatically cross system breaks and frame breaks, appearing in two parts on either side of the break.
By default, the endpoints of slurs that cross system/frame breaks are positioned at least 1/2 space outside the outer staff line and at a suitable position based on the pitch contour of the phrase before/after the break; that is, indicating whether the phrase rises or falls after the break.
If multiple slurs cross the same system break or frame break, such as if a phrase split by a break contains nested slurs, the ends of the slurs are stacked automatically and spaced a minimum of 1/2 space apart vertically.
You can determine whether or not Dorico Pro adjusts the vertical endpoint positions of slurs based on phrase contours in .
In Engrave mode, you can move and edit each slur part separately. This allows you to adjust the start/end height of each slur part independently on each system.
