Re[2]: avoid merging stems

[musicus]

Yes, I want to leave the first g4 with no stem. (a specialty with string instruments: If you have to play the same pitch with two different strings simultaneously, there are two identical noteheads with one stem between)

Slurs seem to be very tricky!

Thank you very much for "\override Slur.details.accidental-collision"! That helps a lot... I checked the details list for Slurs and wondered, if there are any settings, which can provide a better output than attached...

I'd like to avoid "stem-merging" in measure 13 between the upper g2. and the first lower g4. Additionally I'd like to hide the stem of the first lower g4 in m.13 (should be no problem, if the stems don't merge). I tried a couple of things to achieve this, but unfortunately I don't find it.

I'm not sure what you want to do here - leave a g4 notehead with no stem?

Plus, I have a question about the collision between accidentals and slurs. Is there a way to get the accidentals inside the slurs without shaping each of them? (\override Accidental.avoid-slur = #'inside doesn't help - i guess Standard

 Settings restrict the shaping of slurs to a limit?)

articulation.  (The IR is a little misleading on this point.)



\override Slur.details.accidental-collision = 100


it in some of the cases.

That's probably not the reason, more likely because an accidental is not an But increasing the demerit for a collision with an accidental seems to help: Might need to play with the value if avoiding the collision is worse than accepting
