Re: Cross-staff glissando with crescendo and dynamics
Hi David!
The issue, put in a slightly simplified way, is that the Voice context to which
the dynamics are attached has moved away from the Staff under which the
dynamics were originally aligned, leaving lilypond ”in doubt” about under what
staff the \mp should be.
The answer in the linked thread solves this by creating a second Voice for the
dynamics, that stays in the original Staff.
The other solution mentioned, which I’d prefer (but that may be a matter of
taste) would be creating a separate Dynamics context.

For the cross-staff I get 4 of these:
programming error: My pure_y_common is a VerticalAlignment, which
might contain several staves.
continuing, cross fingers
Can someone explain what those warnings mean and how to code the
cross-staff gliss with dynamics and crescendo. correctly?
Getting cross-staff cases right is depressingly hard. I've opened
https://gitlab.com/lilypond/lilypond/-/issues/6306
However, I think you need to clarify how you expect it to
render in the first place. Normally, consecutive dynamics
stay vertically aligned on the same baseline. Here this
does not work, because the mp needs to jump in the
upper staff. What would you do to typeset this if you
were LilyPond?

Re: Cross-staff glissando with crescendo and dynamics
So I figured it out based on:
https://lists.gnu.org/archive/html/lilypond-user/2016-07/msg00266.html
Not an unreasonable solution, but I still don't quite understand the underlying
issue.
