Hi Paul,
turning on/off MeasureGrouping or GridLine is possible via overriding
its stencil.
Also, for MeasureGrouping you could use a new Voice.
Don't know if this is possible for GridLine, I didn't test. ;)
Examples below, taken from NR and modified.
HTH,
Harm
\version "2.16.2"
%% MeasureGrouping
\score {
\new Voice \relative c'' {
\override Staff.MeasureGrouping #'stencil = ##f
\time 9/8
g8 g d d g g a( bes g) |
\set Timing.beatStructure = #'(2 2 2 3)
g8 g d d g g a( bes g) |
\revert Staff.MeasureGrouping #'stencil
\time #'(4 5) 9/8
g8 g d d g g a( bes g) |
\override Staff.MeasureGrouping #'stencil = ##f
\time 5/8
a4. g4 |
}
\header {
piece = "Using \override and \revert of stencil"
}
\layout {
\context {
\Staff
\consists "Measure_grouping_engraver"
}
}
}
\score {
\new Voice
\relative c'' {
\new Voice
\with { \consists "Measure_grouping_engraver" }
{
\time 9/8
g8 g d d g g a( bes g) |
\set Timing.beatStructure = #'(2 2 2 3)
g8 g d d g g a( bes g) |
}
\time #'(4 5) 9/8
g8 g d d g g a( bes g) |
\time 5/8
a4. g4 |
}
\header {
piece = "Using a new Voice"
}
}
%% GridLine
\score {
\new ChoirStaff <<
\new Staff {
\relative c'' {
\stemUp
c'4. d8 e8 f g4
}
}
\new Staff {
\relative c {
\override Score.GridLine #'stencil = ##f
% this moves them up one staff space from the default position
\override Score.GridLine #'extra-offset = #'(0.0 . 1.0)
\stemDown
\clef bass
\once \override Score.GridLine #'thickness = #5.0
c4
\once \override Score.GridLine #'thickness = #1.0
g'4
\revert Score.GridLine #'stencil
\once \override Score.GridLine #'thickness = #3.0
f4
\once \override Score.GridLine #'thickness = #5.0
e4
}
}
>>
\layout {
\context {
\Staff
% set up grids
\consists "Grid_point_engraver"
% set the grid interval to one quarter note
gridInterval = #(ly:make-moment 1/4)
}
\context {
\Score
\consists "Grid_line_span_engraver"
% this moves them to the right half a staff space
\override NoteColumn #'X-offset = #-0.5
}
}
