Greetings Ponderers,
I have written a function to generate custom metronome marks as I want them to
be. But due to limitations of my understanding, this is terribly crude - it has
a hardwired crotchet for the note displayed. What I really want to achieve is
to be able to pass a duration into the function as a parameter and be able to
have quavers or other note values a needed. So for example, I’d like to be able
to say
\metroMark 8 “ = 56”
to specify a tempo of quaver equals 56. The reason I wrote this function is
that using \note and \note-by-number don’t appear to give me the control over
fonts that I want.
I know how to use Scheme arguments and so on, but when I pass a note into the
function as ly:music it seems to upset all the following music in the score, so
I am somewhat perplexed.
metroMark =
#(define-event-function (arg) (markup?)
#{
^\markup \concat {
{
\score {
\new Staff \with {
\remove "Staff_symbol_engraver"
\remove "Time_signature_engraver"
\remove "Clef_engraver"
\override NoteHead.font-size = -4
\override Stem.length = 6
\override Flag.font-size = -4
}
{ \relative c'' { \stemUp c4 } }
\layout {
indent = 0
ragged-right = ##t
}
}
}
#arg
}
#})
Andrew
