Re: Octave shifts in polyphonic setting

Hi,
When entering a piece of music with some one-, some two- and some
three-voiced bars, quite often notes in previous bars go up or down an
octave, when entering new bars.
Restoring this from the first bars affected by adding or deleting
apostrophes or comma's, sometimes lead again to side effects. Rather
frustrating...
In the repertoire that I normally typeset, relative mode is still the
way to go, because small intervals prevail. I find that there are enough
tools to make it manageable and diminish the nuisance:
1) Octave checks, as often as necessary. The beginning of each voice in
a polyphonic construct is an obvious candidate, as are new entries after
long rests. The more large intervals occur, the more octave checks. This
is something I adjust as needed.
2) \resetRelativeOctave is an exceptionally useful command easily
overlooked, especially in situations like you describe.
3) Use more individual \relative commands, i.e. move \relative as close
to the music as possible.
<< \relative {} \\ \relative {} >>
is less error-prone than
\relative { … << {} \\ {} >> … }.
Of course this isn’t practical in piano music where very many <<>>
constructs are needed.
4) Don’t use lots of <<\\>> constructs, but instead something like
<<
\new Voice {
% oneVoice music
}
\new Voice {
\voiceOne
%…
}
\new Voice {
\voiceTwo
%…
}
>>
along with copious spacer rests to bridge over the sections with other
‘voicings’.
This requires quite some planning ahead and again isn’t applicable to
every kind of music.

Most likely, I'd say.
Could you try:
\version "2.19.81"
#(define ((time-parenthesized-time up down upp1 downp1 upp2 downp2)
grob)
(grob-interpret-markup grob
(markup
#:override '(baseline-skip . 0)
#:override '(font-name . #f)
#:override '(font-encoding . fetaText)
#:number
(#:line (
(#:center-column (up down))
#:vcenter "("
(#:center-column (upp1 downp1))
#:lower 0.5 "+"
(#:center-column (upp2 downp2))
#:vcenter ")" )
\new Staff {
\override Staff.TimeSignature #'after-line-breaking =
#(lambda (grob)
(newline)
(pretty-print
(ly:stencil-expr
(ly:grob-property grob 'stencil
\override Staff.TimeSignature #'stencil =
#(time-parenthesized-time "21" "8" "12" "8" "9" "8")
R1
}
The added code in `time-parenthesized-time` should make the markup
discard any font-name-setting you may have done before and forces it
to use 'fetaText.
The additional 'after-line-breaking-override displays the
stencil-expression in terminal.
It's a long list.
Of interest is for example the last section. Because font-name is #f
and font-encoding is 'fetaText a fall-back-font should be used, iiuc.
In my case it's "DejaVuSans":
[...]
(translate-stencil
(12.4918393700787 . 0.0)
(translate-stencil
(0.0 . -1.28037401574803)

What's displayed for you?

Firstly, thank you to all for the various responses to my original
post. I have been away from home until today, so this is the first
opportunity I have had to look at the problem further.
I am using Lilypond 2.19.82 on Ubuntu 18.04. I usually generate
Postscript files and display them as I work.
I now discover that if I generate PDF files instead they appear
correctly. Whether I compile under Ubuntu 16.04 or Ubuntu 18.04, the
resulting PDF files display correctly under both OS versions, whereas
the PS files display correctly under 16.04 but incorrectly under 18.04.
It doesn't seem to depend on the program used to display them: both
Evince (document viewer) and GIMP show the PS files incorrectly in
Ubuntu 18.04. They also print incorrectly.
I suppose that this must be due to an error in whatever underlying
software is interpreting the PS files, assuming that Evince and GIMP
use the same interpreter. I can't see that it can be an error in
Lilypond's compilation, because I get the same result compiling in both
versions of Ubuntu - yet only 18.04 displays and prints the results
incorrectly (no matter which Ubuntu version was used to compile).
In answer to Harm's final question, under both OS versions the font
shown is "Bitstream Vera Sans-Roman".
For now, the practical answer seems to be for me to check my work by
generating PDF files, rather than PostScript.
Of course, I'd be interested to receive any further observations and
suggestions.

Hi Ryan,
You could adjust the offset values to taste...

\ottava #1
d2 d2 d2 d2

Does that get you started? :)

RE: Frescobaldi Log Error -1073741819 on Windows10
Hello Andrew I am sure my issue is neither Frescobaldi or Lilypond related. It is due to some alteration to the file permissions structure on the PCs which showed itself after a Windows update. It may or may not be due to the update. I managed to restore functionality on the laptop via a system restore. This has not been possible on the Desktop. I had been attempting to mess with permissions on that machine and this may have prevented the restore. In any event I am sure the problems are not related to Lily/Fresco. Thanks for all the valued suggestions.

Sometimes it helps to know all is working for somebody else. My result would tend to indicate it is a local problem for you. Are you installing all the W10 updates? There was one just this morning.

Baseline align in TextSpanner
Hi all.
I want to align TextSpanner texts to baseline.
I'm trying to use the code provided by Thomas Morley / Harm in
http://lists.gnu.org/archive/html/lilypond-user/2016-10/msg00365.html
which works very well e.g. with \tempo, but applying \test to
TextSpanner.bound-details.left.text has no effect.
I also tried replacing ly:line-spanner::print in TextSpanner.stencil
with a new function but I couldn't make it work.
An example follows, including Harm's code.
Is there a way to adapt it to my case?
Best wishes.
