Hi here,
I try to do an exercice partition for working on polyrythms with two
simultaneous rythms.
I have a score with two voice, for the two rythme of the polyrythm.
I want a gridline on the top, giving the pulse of the top-voice and a
another gridline in a different collor for emphasis the pulse of the second
rythm-voice.
There is a bug there and I don't knox how to solve it ;)
Here is my code:
\version "2.12.0"
#(set-global-staff-size 30)
#(set-default-paper-size "a4" 'landscape)
global = {
\time 12/4
}
\layout {
\context {
\Staff
\override Staff.VerticalAxisGroup #'minimum-Y-extent = #'(4 . -4)
%\override GridPoint.Y-extent = #'(4 . -4)
\override TupletNumber #'transparent = ##t
\override TupletBracket #'bracket-visibility = ##f
\consists "Grid_point_engraver"
gridInterval = #(ly:make-moment 1/12)
\remove "Time_signature_engraver"
\remove "Clef_engraver"
}
\context {
\Score
\consists "Grid_line_span_engraver"
% center grid lines horizontally below note heads
\override NoteColumn.X-offset = #-0.5
\override NonMusicalPaperColumn #'line-break-permission = ##f
}
ragged-right = ##t
}
\score {
\new ChoirStaff {
\relative c'' <<
\new Staff {
\time 12/4
% hides staff and notes so that only the grid lines are visible
\hideNotes
\override Staff.BarLine.transparent = ##t
\override Staff.StaffSymbol.line-count = #0
% dummy notes to force regular note spacing
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #red
\times 12/4 { c4 c c }
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #red
c4 c c c c c c c c c c c
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #red
c4 c c c c c c c c c c c
}
\new Staff \with { instrumentName = \markup \center-column {Ex:
5 6 } } << \new Voice { \voiceOne \relative c'' { \time 12/8
r4 e r r e r r e e r r e | e e r e~ e e e~ e r e~ e e | r e e e r r e r
e r e e | } } \new Voice { \voiceTwo \relative c' { \global
f4 r r f r f f r f r f f | r f f r f r r f f r r f | f~ f f f f r f~ f r
f~ f r | } } >>
\new Staff {
\time 12/4
% hides staff and notes so that only the grid lines are visible
\hideNotes
\override Staff.BarLine.transparent = ##t
\override Staff.StaffSymbol.line-count = #0
% dummy notes to force regular note spacing
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #blue
c4 c c c c c c c c c c c
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #blue
c4 c c c c c c c c c c c
\once \override Score.GridLine.thickness = #4.0 \once \override
Score.GridLine.color = #blue
c4 c c c c c c c c c c c
}
>>
}
}
Best and thanks
