Hi,
I did some research on this topic, focusing on \note-by-number, which is
called in \note.
I've found that \note-by-number is _always_ disturbed, if _any_ font-name
is set. But \musicglyph not, for _every_ font-name-setting.
The difference seems to be that \musicglyph clears font-name, setting it to
#f.
\note-by-number does not.
Coding the same in \note-by-number seems to solve the issue. This needs
more testing, though, and _if_ it's the way to go, should be done in
\rest-by-number as well.
Code-examples:
\version "2.19.26"
%% The following _always_ works
%%{
\markup {
\typewriter #"\\musicglyph #\"noteheads.s0\""
\musicglyph #"noteheads.s0"
}
\markup {
\typewriter "\\note #\"8.\" #UP"
\note #"8." #UP
\typewriter #"\\note #\"1.\" #UP"
\note #"1." #UP
}
%}
%% The following _never_ works, regardless which font-name is specified.
%%{
\markup
\override #'(font-name . "Times New Roman")
{
\typewriter #"\\musicglyph #\"noteheads.s0\""
\musicglyph #"noteheads.s0"
}
\markup
\override #'(font-name . "Times New Roman")
{
\typewriter "\\note #\"8.\" #UP"
\note #"8." #UP
\typewriter #"\\note #\"1.\" #UP"
\note #"1." #UP
}
%}
And the following bug can be observed (not related to the current
topic,
I think), was ok with 2.18.2:
%%{
\markup \override #'(font-name . "Times New Roman") "\\<==what?"
%}
Replacing note-by-number in define-markup-commands.scm with the code below
seems to solve the issue (changes between the semicolon-lines) and the
reported problem with other fonts like profondo, etc
Please test.
