lilypond-learning: Simulating a fermata in MIDI
Simulating a fermata in MIDI
............................
For outside-staff objects it is usually better to override the object’s
‘stencil’ property rather than its ‘transparent’ property when you wish
to remove it from the printed output. Setting the ‘stencil’ property of
an object to ‘#f’ will remove that object entirely from the printed
output. This means it has no effect on the placement of other objects
placed relative to it.
For example, if we wished to change the metronome setting in order to
simulate a fermata in the MIDI output we would not want the metronome
markings to appear in the printed output, and we would not want it to
influence the spacing between the two systems or the positions of
adjacent annotations on the staff. So setting its ‘stencil’ property to
‘#f’ would be the best way. We show here the effect of the two methods:
\score {
\relative c'' {
% Visible tempo marking
\tempo 4=120
a4 a a
\once \hide Score.MetronomeMark
% Invisible tempo marking to lengthen fermata in MIDI
\tempo 4=80
a4\fermata |
% New tempo for next section
\tempo 4=100
a4 a a a |
}
\layout { }
\midi { }
}
[image src="" alt="[image of music]" text="image of music" ]
\score {
\relative c'' {
% Visible tempo marking
\tempo 4=120
a4 a a
\once \omit Score.MetronomeMark
% Invisible tempo marking to lengthen fermata in MIDI
\tempo 4=80
a4\fermata |
% New tempo for next section
\tempo 4=100
a4 a a a |
}
\layout { }
\midi { }
}
[image src="" alt="[image of music]" text="image of music" ]
Both methods remove the metronome mark which lengthens the fermata from
the printed output, and both affect the MIDI timing as required, but the
transparent metronome mark in the first line forces the following tempo
indication too high while the second (with the stencil removed) does
not.
