The memory management stuff has been dealt with mostly.  Guile-2.0
however is aware of character encodings (meaning that it knows better
than everyone else how to do things but not good enough to actually
work) so the port is stuck in that area, and not being able to work with
the test cases (and some LilyPond-internal files) means not being able
to look for other problems.

Also, there is no sane strategy for dealing with precompiled .go files
yet.  configure has an option for allowing Guile-2 but the result fails
in those respect so it's off by default.

score-with-notes.osc
Description: Binary data

If you by "play it" mean getting sound from it, set up whatever OSC
enabled player you prefer, making sure the OSC-path \myNote reacts to
something having a start time and a 'freq' parameter.

For fun i included messages and parameters with symbolic names for
time-signatures, beams, and tuplets in this prototype file, ie. it could
be used to carry layout info for notation for LY.

MIDI is fixed.  OSC (the protocol) doesn't care, which is perhaps
confusing, but is what could make it useful in this context.

If you want to gain a basic understanding you can check out
SuperCollider, esp. the docs relating to NRT synthesis, perhaps also
simple clients like Matt Wrights sendOSC.

​That worked very well! Thanks!

Can anyone comment on why \override VerticalAxisGroup #'minimum-Y-extent =
#'(-5 . 40) didn't work?​

For your layout block, try (as one possibility):

 \layout {
  \context {
\Lyrics
  \override VerticalAxisGroup #'nonstaff-nonstaff-spacing =
#'((basic-distance . 5))
  }
  }

The relevant section in the Notation Reference is

Changing basic distance between stanzas

[Joshua Nichols]

I am looking for a tweak to decrease or increase the vertical distance
between multiple stanzas.

I found this online (not in the manual):

\context {
\Lyrics
minimumVerticalExtent = #'(0 . 0)
  }

​But, when I compile (with any number in the variable) I get this message:

warning: cannot find property type-check for `minimumVerticalExtent'
(translation-type?). perhaps a typing error?

warning: skipping assignment


Here is an example:


\version "2.18.2"

notesA = {
  c'
}

vOne = \lyricmode {
  a
}

vTwo = \lyricmode {
  b
}

\score {
  <<
\new Voice = "mel" { \notesA }
\new Lyrics \lyricsto "mel" { \vOne }
\new Lyrics \lyricsto "mel" { \vTwo }


  >>
  \layout {
  \context {
  \Lyrics
  minimumVerticalExtent = #'(0 . 0)
  }
}
}


Help?

MusicXML2Ly: Problem with minor chords

[Johan Vromans]

Hi,

In the attached XML, the minor D chord

  

  D

minor
  

is translated into

  d:m5

and apparently not understood -- lilypond renders it as a major D chord
without warning.

Dm(maj7) becomes d:maj7m5.

A similar thing happens to half-diminished chords: Bm7b5 becomes b:dim5m7.

Is this a known problem? Googling for "musicxml2ly minor" did not return
anything relevant.

Currently your only option seems to be keeping Guile deliberately old (or try

So, it appears that Lily won't build against guile-2.*, yes? Is this a

I'll just re-state my earlier use-case (in the devel- mailing list) for
good measure that extends divisi staves.

Let's say I have a 4-horn group. The way these appear in the score depends
on the complexity of their parts, in the following configurations:

1. Each has their own staff
2. They can be grouped into a 1/3 staff and 2/4 staff.
3. They can be grouped together into a single staff.

I imagine them falling into a "keep-alive-tree" like this:

All Horns Group staff
|
|-- Horns 1/3 Joint Staff
|  |
|  |-- Horn 1 Staff
|  |-- Horn 3 Staff
|
|-- Horns 2/4 Joint Staff
   |
   |-- Horn 2 Staff
   |-- Horn 4 Staff

The expected behavior in this (albeit hypothetical) situation would
automatically allow for each branch to hide its own higher nodes while
allowing the other branches to join together at their highest available
node.

For example, say I want to show the Horn 1 part in its own staff. This
would FORCE Horn 3 to show up on its own staff, but would ALLOW Horns 2/4
to appear on their joint staff, to get:

- Horn 1 Staff
- Horn 3 Staff
- Horns 2/4 Staff

Alternatively, Horn 3 could jump to the joint staff to minimize the number
of extra staves, like:

- Horn 1 Staff
- Horns 2/3/4 Staff

As discussed before, I couldn't find a good way to allow this kind of
"nested" divisi functionality because it seemed like the trigger acted more
like a global on/off switch. I realize this could really be a coding
nightmare, but could be a really helpful feature, too, for automatically
splitting/combining frenched staves.

Forgive me if I didn't explain that very well.

Best,
Abraham

Thank you!

1a. The "frenched score with ScoreMarks / MarkLine / whatever” use-case is my 
main one. (This use-case would, I assume, include “large time signature” lines, 
chord symbols, etc.?)

1b. Essentially identical — but not “marks” exactly — is the “dialogue” 
(TextLine) above/below a theatre work (e.g., musical, opera, narrated). Again, 
in a frenched score situation, that line should live and die with the “last 
context standing”.

2. The “divisi staves” use-case is also a primary feature/request for me. 
Similar/analogous use-cases: a two-stave harp part compressing (if necessary) 
to a single staff in the full score.

To be honest, I can’t really think of any other significantly different 
use-cases at the moment… but I have no doubt that they’re out there, and if I 
think of one, I’ll be sure to let you know about it.

Thanks! Can’t wait for this feature to be available “in the trenches".  =)

Keep alive together - call for use cases

[Mark Knoop]

I've been working on some patches to enable more flexible uses for the
Keep_alive_together_engraver. Whilst I've achieved my particular use
case, David K is (rightly) keen that any changes might also address (or
at least not rule out) other potential improvements.

(If you're interested in the code, look here:
https://codereview.appspot.com/308910043/)

So if I could ask users for any situations where they can imagine this
engraver helping, that currently don't work, or don't work easily. I'll
start by describing my case, which came up on the list recently.

Duplicating rehearsal, tempo, volta marks etc at multiple vertical
positions in an orchestral score is possible with a custom MarkLine
context (http://lsr.di.unimi.it/LSR/Item?id=1010), however this
technique currently doesn't work in a Frenched score, as there may be
passages where e.g. the brass are tacet so two MarkLines would be shown
together. My fix makes it possible to set a context (Staff or MarkLine)
to be kept alive only while there is another Staff in the group.

See also the temporary divisi staves example here:
http://lilypond.org/doc/v2.19/input/regression/a6/lily-436997bb.ly
as another use of the engraver.

Many thanks for your input.

Obviously.  I'm commenting on a misunderstanding vs. potential use of
OSC raised in this thread.

Bay Area

[Urs Liska]

Hi everyone,

I'm really looking forward to attend the GSoC mentors summit on the last
weekend of October in Sunnyvale. I intend to be in the Bay Area somewhat
earlier, depending on how many days of leave I can negotiate with my
family ;-)

So I expect to be around SF ca. Oct 25-27(28) and would be happy meeting
LilyPond people during these days. I'll be mainly interested in
sight-seeing at that occasion, but talking about LilyPond is of course
not prohibited!

Please get in touch with me if you're interested in meeting me, if you
have a few spare hours to show me something interesting etc.

For social as well as economic considerations I'd also be glad if
someone would be able to provide me with a bed for one or more night(s).
But I'll at the same time look for commercial accomodation right now, as
there seem to be *still* some reasonably priced beds available on AirBnB ...

Best
Urs

LilyPond does not use Midi as a storage format but as an output format,
just like PDF is an output format.  The salient point of having a Midi
backend is not to store information but to pass it on.  Without a large
body of soft- and hardware able to process the resulting OSC files, this
is a pretty pointless exercise.  MusicXML export would likely be quite
more useful for letting LilyPond interface with other applications while
preserving more information about the original input.
