Add slurs across multiple lines

[AurisStd]

While slurs do work cross multiple measures, they seem to break once you want them to go past a line:
For example, I used this code in the playground compiler
E4{slur s1}.4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4 | E4 E4 E4 E4{slur s1}

Do you have some insights where such a scenario would really be needed? Do you actually have some music notation where a slur would span that far and you actually have multiple line breaks?

It should be fairly simple to fix the problem if there is only one line-break. But I have my doubts if a slur should go across multiple systems. Slurs are currently handled by the respective start & end note.

It would need a bigger redesign to remember slurs across systems until it ends (and draw them at a reasonable location)

Phrases can be indicated by a slur, and in some cases this can span multiple lines(I do have examples where this happens), in which case I would need a notation in which a slur spans that far.

I added #2261 as a future work-item. If possible provide some reference music sheets as it helps during implementation to cover your needs. Creating some artificial test cases always works, but the more real-world data, the better. 😉

The Czerny etudes are the specific implementation for why I needed this in the first place, found here
