I managed to print custom key signatures from a microtonal font. One problem
remains, and I wonder if anyone can help me.
In my init file persian.ly I have defined variables for various key signatures
and keys, e.g. for Shur in E
shurEKey = \markup{
\translate #'(0 . 1) \SORISYMBOL
}
shurE = #`(
(3 . ,SORI)
)
were SORISYMBOL is my UTF-8 code form the font I've loaded.
My source file looks like this:
\include "persian.ly"
\score {
\relative c' {
\set Staff.keySignature = \shurE
a b c
}
\midi { }
\layout {
\context {
\Score \override KeySignature #'text = #shurEKey
}
}
}
which works fine. I would instead like to put the statement
\Score \override KeySignature #'text = #shurEKey
not in the layout{} but in my music expression, because now I can't change key
signature in a piece.
If I try that it will complain that shurKey is not a markup.
Can anybody explain what the problem is?
Thanks,
Kees
