Oh yes, definitely! Beam 'positions is my friend. The challenge in this case
is that the vertical values passed to 'positions is *relative to different
staves* if you staff-\change notes.
So when we build an example like this one ...
%%% BEGIN %%%
\version "2.11.34"
\new PianoStaff <<
\new Staff = RH {
\time 9/8
\override Staff.VerticalAxisGroup #'minimum-Y-extent = #'(-10 . 20)
\override Stem #'direction = #down
\override Beam #'positions = #'(-7 . -7)
c'8 [
c'8
\once \override Stem #'direction = #up
\change Staff = LH
c'8 ]
\change Staff = RH
c'8 [
\once \override Stem #'direction = #up
\change Staff = LH
c'8
\change Staff = RH
c'8 ]
\once \override Beam #'positions = #'(7.5 . 7.5)
\change Staff = LH
\once \override Stem #'direction = #up
c'8 [
\change Staff = RH
c'8
c'8 ]
}
\new Staff = LH {
\clef bass
s1 * 9/8
}
>>
%%% END %%%
... we start out with one pair of values here ...
\override Beam #'positions = #'(-7 . -7) % notice negative values
below RH staff
... but we are forced to tweak by hand and set another pair of values here
...
\once \override Beam #'positions = #'(7.5 . 7.5) % notice positive
values above LH staff
... all just to say "vertically align my beams ... no matter what the
'staff' of the first note."
So what would be ideal would be either ...
1. a way either to prevent staff-\changes from causing us to have to make
multiple settings to Beam 'positions, or
2. a way to reach into the object model and set Beam 'positions in terms of
a "remote" staff.
Is there some deep Scheme magic that might allow for the latter?
