Engraving Options > Slurs > Endpoint positioning > Vertical offset from notehead on line.
The situation is as illustrated in this engraving option, but when I change this value, nothing happens. Isn’t this strange?
The Vertical offset from notehead on line value will only be used for end points of slurs positioned inside the staff. When the slur end points are outside the staff, the Minimum gap inside slur curvature to avoid collisions value is used instead.
In the situation of the first GIF I posted in OP, the Vertical offset from notehead in space option seems to be working. But…
If I do it, I won’t get the same result as @pianoleo. When the notes are lower than the middle staff line, the Vertical offset from notehead on line option seems to be working like GIF below. It’s strange.
I also made examples like these below, with Vertical offset from notehead in space set to 3 spaces, and Vertical offset from notehead on line set to 1/2 space.
The results are inconsistent between up-stem cases and down-stem cases. I’m not sure what the rules are for which option will be used in which case.
To me, the results in bars 14-18 seem to reflect both options correctly.
