HorizontalBracket carries an array of NoteColumn grobs, so the bound
is already available for the broken spanner:

\version "2.15.11"

\layout { ragged-right = ##t }

\new Voice \with {
  \consists "Horizontal_bracket_engraver"
  \override HorizontalBracket #'after-line-breaking =
  #(lambda (grob)
 (let* ((orig (ly:grob-original grob))
(broken-intos (ly:spanner-broken-into orig)))
   (and (pair? broken-intos)
(>= (length broken-intos) 2)
(eq? (car (last-pair broken-intos)) grob)
(let ((cols (ly:grob-array->list (ly:grob-object grob 'columns
  (set! (ly:grob-property grob 'edge-height) '(0 . 1))

Yeah!
Thank you for this quick answer.

SystemStartBar did not come into my mind!
It is indeed a simple and efficient solution (I increased the thickness
of SystemStartBar from #1.6 to #1.9 so it looks like a real bar line).

Thank you very much!

Begin with a staff bar at left edge

2011-09-14 Thread Xavier Scheuer 
Hello,

I'd like to add some measures (engraved thanks to LilyPond) to an
existing *scanned* score.
So I begin with a currentBarNumber different from 1, I remove the
TimeSignature stencil at the beginning, etc.
And as there are only a very small number of measures to insert I
compile with  -dpreview  in order to have a cropped image, ready to be
inserted.

What I'd like to get but I did not managed to is to begin the staff
with a _normal bar_ ( \bar "|" ) at the left edge (because these
measures are to be inserted in the middle of an existing [scanned]
score).
I tried to modify the place of "staff-bar" in
  Score.BreakAlignment #'break-align-orders
but I am not able to print a normal bar at the extreme left of the
staff (left edge).

Would you have some advice ?
Thanks in advance.

Cheers,
Xavier

Colin,

After decompression of the "official" Lilypond 2.15.11 ppc download its 
application icon is covered with the circle and slash indicating 
incompatibility. The download was from the Lilypond.org site. I have not 
attempted local compiling except for some very early versions using   Fink 
open-source file management. That was also many computers and operating systems 
ago.

As stated, 2.15.8 downloaded and runs as expected.

If I can assist in any way, I'll do my best.

Change beam grouping

2011-09-14 Thread Sven Axelsson 
Hi list.

This is probably in the manual, but I can't find it so I'm asking you
all. In a sequence like

{ b16. b32 b32 b16. }

the default is to have a beam that connects the two shortest notes,
like the first bar in the attached image. I want the beaming so it
always makes a beamlet point towards the corresponding dotted note, as
in the second bar of the image.

How can I set it up so this happens automatically, both in 8. 16 and
in 16. 32 groups?

Thanks

The problem is that the score is quite large, and the log gives no 
indication at all about where the error is coming from. I guess I can 
try commenting out different sections to see if I can isolate where 
the error is happening.


Nick, if it helps, the problem will be with either a slur or
a tie.  The code is trying to find the height of a slur or a
tie at a particular x value (or vice versa) and finds no slur
or tie at that point.  Some code in this area is relatively
new, so it is possible you have hit a code error.  If you
can narrow it down that would be very helpful (or it may
help you find a problem in your ly code :).


Ok, the following small example reproduces the error on my system
with 2.15.11:

%==
\version "2.15.11"

\language "english"

fingering = {
\set fingeringOrientations = #'(left)
\set strokeFingerOrientations = #'(up)
\override Fingering #'avoid-slur = #'inside
\override StrokeFinger #'avoid-slur = #'outside
}

\relative c'' {
\fingering
16( b)
}
%==

If I get rid of the right hand fingering then the error goes away,
and if I comment out the override for StrokeFinger #'avoid-slur then
the error also goes away but the log contains the warning:

/home/nick/lilypond/examples/test.ly:14:13: warning: Ignoring grob
for slur: StrokeFinger. avoid-slur not set?

The minimal example is (the normal fingering "-1" does not have any influence, 
so it should be removed, too, and the language is also not relevant):
%==
\version "2.15.11"

\relative c'' {
  \set strokeFingerOrientations = #'(up)
  \override StrokeFinger #'avoid-slur = #'outside
  16( b)
}
%==

This example shows clearly that StrokeFinger is to blame here.

The warning appears only with #'avoid-slur=#'outside, not with 'inside. 
However, the actual value of strokeFingerOrientations is not relevant (as long 
as you set it to some value), the warning appears both with #'(up) and with 
#'(down).

That's definitely a bug. The StrokeFinger seems to be missing the avoid-slur 
property (and there seems to be a regtest missing for StrokeFinger).

I guess only Mike Solomon can answer that question, since he didn't describe

Use regular.ly with tuning=#53 or some other equal
temperament that gets close enough for you.  Normally
notated notes will then be Pythagorean.

Re: Just Intonation MIDI file

2011-09-14 Thread Nick Bailey 
Well, the way we did it was to retune the synthesiser fluidsynth using the 
tunings (?) command. It was a slightly different problem because we wanted 19-
ET rather than messing about with pythagorean adjustments, which might have to 
change every time you modulate anyway? We found that not many commercial 
synths obey the midi tuning protocol (in fact none of the ones we looked at).

Off topic, I'd be interested in why you want to teach singers to sing out of 
tune anyway :D (that was a troll :) )

Here's a video about the 19ET stuff...

Re: Just Intonation MIDI file

2011-09-14 Thread flup2 

The MIDI command "pitch bend" allows to change intonation by intervals
smaller than a half tone. For instance, this is the way softwares like
Sibelius render micro-intervals.

Some MIDI devices use special tuning maps to reproduce different
temperaments (equal, Pythagore, etc.)

I guess it's a possible way to achieve such result.

This YouTube by Hajo (dl1sdz) claims to have generated a just

BWV-988-Var-12-Just.AVI



How does one do this?

I can find "just intonation" in the glossary but not in the rest of

I am interested in generating sound files for singing practice using
