Re: Frescobaldi on Arch Linux

[Andrew Bernard]

I see the same exact versions, but no PDF output displayed in the
music view. Have not had this before. So the question is, how o
troubleshoot this, having checked for versionitis?

I think that removing all the margins is the functionality "crop" is
supposed to add to LP. To generate the equivalent cropped and packed
image without this facility would be quite tedious to do (unless
someone has a trick for doing it?).

If you just want to crop the whole page image, you can do that easily
at the end of a normal run with the usual utilities. If you require
LP to set the entire score on a single page, just use a very long
custom page (as in NR §4.1.2: width, then length).

David.

Re: Restrict midi2ly to one voice

[Hans Aikema]

"midi2ly converts tracks into Staff and channels into Voice contexts"

so make your midi-file contain all music on a single channel should result in a 
single voice

apparently, given the results, your midi is currently 4 channels with music

Re: ANN: Frescobaldi 3.1.3

Dear friends,

Il giorno sab 26 dic 2020 alle ore 14:08 Wilbert Berendsen

> The source tarball is uploaded, packaged releases will probably follow

the prebuilt application bundle for macOS can be found at
https://github.com/frescobaldi/frescobaldi/releases
It should run on macOS 10.11-10.15 and I expect it to run also on
macOS 11, although I have no way to test it.
If you are running macOS 11, I would be grateful if you could test the
application and report the results.
As with the previous versions, the prebuilt application is still
lacking the Documentation Browser and the SVG View (more details in
the release page).

Frescobaldi can be installed also with MacPorts, resulting in a fully
functional application (including the Documentation Browser and the
SVG View) on macOS 10.11, 10.14 and 10.15.
It can be installed also on macOS 10.13, provided that Xcode 10
(instead of Xcode 9) is installed.
On macOS 10.12 the installation fails, but I can give instructions to
make it succeed resulting in an application lacking the Documentation
Browser and the SVG View.
On macOS 11 on the x86_64 architecture the installation fails, but I
can give instructions to make it succeed resulting in an application
lacking MIDI support.
On macOS 11 on the arm64 architecture the installation fails due to a
possible bug in MacPorts and I currently have no solution.

I will update the Homebrew cask for Frescobaldi shortly.
The cask installs the prebuilt application mentioned above, so it
lacks the Documentation Browser and the SVG View.
I plan to turn Frescobaldi into a Homebrew formula again, so that it
results in the fully functional application.
I will need help in doing this and I will write about it soon in a
separate thread.

Best wishes of a happy new year!

Re: text at the end of a multimeasure rest

[Josiah Boothby]

So in my mockup I forgot to include the reason I hadn't wanted to use \mark
: I'd already been using \mark to delineate sections:

Time = {
  \mark\markup{ Minuet }
  \repeat volta 2 { s1*4 }
  \repeat volta 2 { s1*4_\markup\right-align{ fine } }
  \mark\markup{ Trio }
  \repeat volta 2 { s1*4 }
  \repeat volta 2 { s1*4_\markup\right-align{ D.C. al fine } }
}

Either the sectional headings or the roadmap text should be applied with
\mark, but not both. I'm of half a mind to do a feature request for
beginning and ending texts to be applicable to repeats (something perhaps
like \repeat \volta 2 { \with \startTextAbove "2x only" \endTextBelow "D.C.
al fine" } { \notes } but the current correct solution is probably just
evading me :P )

The short answer is because I didn't know about \omit.

The longer answer is that what I do now is a direct descendant of what I
figured out to do back in 1996 or so.  At that time, the options were
very different from what they are now.  And there was a lot less
support/documentation for how to write music without barlines.

Add a vertical line to TextSpanner

[Thomas Morley]

Hi,

I'm trying to add a vertical line to the left side of a TextSpanner.
This line should connect the TextSpanner with the middle line of the
StaffSymbol.

Here a manual done example code:

{
  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -2.85)
  b1\startTextSpan
  b1\stopTextSpan

  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -4.5)
  b1\startTextSpan
  b''1\stopTextSpan

  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -5.7)
  b1\startTextSpan
  b''1^!\stopTextSpan
}

Could this be done automagically?

Thanks,
  Harm

I wasn’t posing that as a possible solution to your problem.  =)
I’m just [still] wondering why Laura Conrad, as a regular course of action, 
uses her particular method of “hiding” barlines.

Re: Repeats with bar-engraver removed

Dear Pierre Perol-Schneider,  I am sorry, but \bar ".|:" and \bar ":|." did
not work.
Dear Kieren MacMillan, I am sorry, but "\omit BarLine" did not work.
Indeed, it did omit bar lines, but the composition ran off the left margin
of the page.
Dear Laura Conrad, I am sorry, but your solution also did not work, the
behaviour was the same as that of Ms. MacMillan's solution.

For all of the above three tests, I included the Bar_engraver and removed
the statement regarding \set ScoreTiming.

Dear j...@abou-samra.fr, it looks like your solution does indeed work!
Thank you for your careful work.

And to answer one question which arose: the idea to remove the bar engraver
is included in the manual under chant music.

I would like to thank everyone who provided answers!  This is not something
I could have found time to figure out myself, and I certainly wish one of
the simpler solutions would have worked.

Happy New Year! Bonne et heureuse année!

Sincerely,
John Staško

Restrict midi2ly to one voice

[Stephan Schöll]

Hi

I have a self-recorded/-created midi file which I have quantized and
simplified to death (lengths and durations to 1/16, no overlaps). Let's
assume it's the the left hand part of a piano score. Now I want to
convert it to a lilypond file using

midi2ly.py -d 16 -s 16 -o "\MITM_Piano_LH.ly" "\MITM_Piano_LH.mid"

This works without errors on the command line. But lilypond generates 4
voices and distributes the notes all over these voices which is a mess.
I optimized the midi file in a way that midi2ly might simply produce one
voice.

How can I tell midi2ly to create only one voice? I couldn't find any
helping hint in the documentation
https://lilypond.org/doc/v2.18/Documentation/usage/invoking-midi2ly.en.html.

Best Regards
Stephan
