Hi Richard:
In a complex score with a DynamicsStaff placed above the music for
markups and another below for the dynamics an unusually large space
opened up below the music and above the dynamics.
I pared the complex score down to this MWE:
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
\version "2.24"
marks = {
%This line is needed.
\repeat unfold 40 {s1 }
}
music = {
\repeat unfold 80 {c''1 }
}
dyns = {
\repeat unfold 80 { <> \f c''1 }
}
\paper {
%this line is needed.
system-system-spacing.minimum-distance = 15
}
\score {
<< \new Dynamics <<\marks >>
\new Staff << \music >>
\new Dynamics << \dyns >>
>>
}
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
In this example the extra spacing disappears after the third system.
Changing the \repeat unfold 40 to 80 in the marks section ran the extra spacing out to the end. Also I found that changing that block to
marks = {
%This line is needed.
\repeat unfold 80 {s4-\markup "A" s2. }
}
with some actual markup in there made the extra spacing go away. I'm guessing that the spacing system couldn't quite figure things out with just spacer rests to work with. But that's just a guess.
