Re: Beam.positions affecting space between staves

[Karim Haddad]

Thank you a lot all of you for your feedbacks.

I have figured it out, however it is not that straight forward thing.

First let me show you the not so MWE example in "real" context, ie in the score 
i am producing for Keyboard and live elecronics. The 01.png screenshot is what 
i get  at first. And thanx for the crossStaff suggestion by Xavier, i adjusted 
it in 02.png. Ok I admit, the score is scarry (but in rpogress), but waht the 
hell... it was saturday night time :-)

[The change/hack is on the first beat of the 5/8 measure (third meas.)  the 5/6 
tuplet.]

So my solution  as a MWE that i posted first was the following:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.25.1"
 
"one"=
{
%%%%%%%%%%%%%%%%%%%%%%% MESURE : 1 %%%%%%%%%%%%%%%%%%%%%%%
\tempo 4 = 60
\time 4/4
\once \override Beam.positions=#'(6  . 6)
\override NoteHead.transparent=##t
\override NoteHead.no-ledgers = ##t
\override Accidental.transparent = ##t
c'8 c'8 c'8 c'8
\revert NoteHead.transparent
\revert NoteHead.no-ledgers
\revert Accidental.transparent
c'4
c'4
|
} 
 

"two"=
{
\time 4/4
\autoBeamOff
\stemUp
\crossStaff { c'8 c'8 c'8 c'8}
\autoBeamOn
\stemNeutral

c'4
c'4
|
} 
 
\score { 
 { 
<<
\new PianoStaff
 << 
\new Staff = "up" {
\one
}

\new Staff = "down" {
\two
}
 >> 
 >> 
} 
\layout {
ragged-last = ##f
indent = 0.0
        \context {\PianoStaff
          \consists #Span_stem_engraver
            }
            }
            }
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


But i must admit, i hoped a more simpler solution involving Grobs. But here I 
am a novice. I mean by that, a way to override the spacing without all the 
above overrides. But what the heck, it works with this solution so i will live 
with that. :-)


I Thank you all a lot, and all the Lilypond community and dev team.
Love all

Best
Karim
