I think you need to add the following to the make-music section of the
make-tremolo function:

'tremolo-type dur

I'm not sure when this was changed, but this made it work in 2.15.19.
I haven't looked at this in depth so there could be other issues.

For future reference, the way I debugged this was to compare the
output of \displayMusic of the standard \repeat tremolo ...  what the
\tremolos ... function created and noticed the missing parameter.

You are right.  I was looking at the MMR and did not realize the rest
was actually merged!  We have an expression for that in French:

That works, and that works great AFAICS.  I have sent in the the French

If you compare LilyPond to most engraving software, I'd rather say the
opposite.  And pirating software does not make it free, which leaves
you with truly free software as the only option sometimes.  And
because it is free, it has the same improving potential as any other
software.

I had no problems compiling the LSR-Snippet with "2.14.2" and "2.15.13".
Of course this snippet doesn't define merging MultiMeasureRests.

Also, I didn't notice any problem with the code given by Wilbert when using
"2.14.2".

In the code below I integrated Neil's suggestion making the second MMR
transparent. (To avoid printing a second MultiMeasureNumber I made the
second number transparent manually. As Neil remarked an engraver would be
better, but this is beyond my knowledge.)
But with "2.15.13" there is a difference between merging a single MMR and
merging \compressFullBarRests R1*9. Perhaps a bug?

I added some conditions reading out the measure-count and the used
lilypond-version to deal with the behaviour of the different versions.

It's a hack, but I hope it will work with "2.14." and "2.15". Please let me
know.

beginners question Lilypond

2011-11-20 Thread Kim van Aurich-Hoogenraad

Dear all,

 

Is there someone who could please help me. I'm a absolute Lilypond beginner. 
And to make things worse, I'm blind as well, so I can not check the printed 
output (and there is only a four years old in the house able to read little 
music...).

What do I do wrong in the below example???

 

I want:

- a landscape printed music sheet (with very big sized staffs "so, when I print 
it on my graphic braille printer, I can check it myself, before I print it in 
normal size");

- Each staff only has a few notes and in front of each staff I want a number.

PHs.: And what is a good/normal landscape size for normal sighted people to use?

 

\version "2.14.2

\layout { }

   #(set-default-paper-size "a4" 'landscape)
  #(set-global-staff-size 26)

\header {

  title = "Example: Twinkle twinkle little star"

"

melody = \relative c' {

  \clef treble

  \key c \major

  \time 4/4

 

1. = \new Staff } g4 g4 d4 d4 \ e4 e4 d2 \

2. = \new Staff ] c8 c8 c8 c8 b4 b4 \ a4 a4 g2 \

3. = \new Staff ] d4 d4 c4 c4 \ b4 b4 a2 \

4. = \new Staff ] d4 d4 c4 c4 \ b4 b4 a2\ 

5. = \new Staff ] g4 g4 d4 d4 \ e4 e4 d2 \

6. = \new Staff ] c8 c8 c8 c8 b4 b4 \ a4 a4 g2 \

 

}

 

I also want color added to my notes, but I'm not sure whether it is better to 
use color per bar or pitch related color.

And both syntaxes are beyond my skills (I do not get any color "or so I think, 
but maybe the inkt of the printer was finished...").

I want:

- black for all notes play on the e string = e f g and higher;

- blue played on the b string = b c (middle c) d

- green played on the g string = g a

- red played on the d string = d e f

- orange played on the a string = a b c 

- gray played on the bass e string = e f g 

 

Can someone please add the correct color syntaxes to the above example for me?

I would be very, very grateful.

 

Thanks,

Kim

Usage of LilyPond fonts in a web app

2011-11-20 Thread Philip Peterson

Hi all,

My friend and I are wanting to use the fonts LilyPond uses for engraving in
a web app. Since one cannot rely on the user having those fonts installed,
we would like to convert those fonts using
typeface.js.
If we make the converted fonts open-source, would it be permissible to use
the font on the site (which uses the converted fonts), while the site
itself is not open-source?

Make merge rests on positioning work

2011-11-20 Thread Xavier Scheuer

Hi,

Someone on the French users mailing list basically wants the features of
  \override RestCollision #'positioning-done = #merge-rests-on-positioning

Issue #1228 is tagged as "Patch-abandoned", LSR #336 is not working
with current version.
http://code.google.com/p/lilypond/issues/detail?id=1228
http://lsr.dsi.unimi.it/LSR/Item?id=336

However, the code given by Wilbert in the first comment works, except
that the MMRs appears below the 3rd (middle) line, instead of below the
4th line (normal position).  Apparently
  MultiMeasureRest #'staff-position  changed from #0 to #2 for the
normal position between 2.12 and 2.14/2.15.

Could a "power user" give some help in order to make it work correctly
with 2.14/2.15?  Even better if a dev could implement it (correctly) in
LilyPond, but in the meantime I'm sure the French users would be happy
with a hack!
