I am using 2.18.2 (last stable version according to lilypond.org, also
the version packaged by standard Linux distros).

After installing 2.19 (thanks for providing an install script -
I am still somwehat surprised that it worked out-of-the-box on my
stable Debian!), it is indeed better.

It doesn’t in LilyPond 2.19.53, which version are you using?

Do you really want to have three separate voices? If so you should try
2.19. The results look much better IMO.

autochange and multiple voices

2017-01-20 Thread Jérôme Plût 

Consider the following score:
\new PianoStaff <<
  \new Staff = "up" {
  <> % this should do nothing...
  <<
\new Voice \relative { e''4 f e }
\new Voice \autochange \relative { a'~ a g }
\new Voice \autochange \relative { c'~ c b }
  >> }
  \new Staff = "down" { \clef F <<
\new Voice \relative { a d, e }
  >> }
>>


Problem 1: why, on the third beat, is the alto voice (playing a g')
displayed on the "down" Staff?

Problem 2: delete the line saying "<>" and recompile. Now
all hell breaks loose: the score acquires a third staff, which even
eats the soprano on the third beat...
(on the other hand, the chords on beats 1 and 2 are now nicer).
Why? (I guess that the "up" Staff had a default, empty voice
through the "<>" - is that correct? but it does not explain all).

autochange with multiple voices

2015-08-18 Thread Nik Repka 
 I'm not top posting.

I am following the syntax of this snippet: 
http://www.lilypond.org/doc/v2.15/Documentation/snippets-big-page#keyboards-using-autochange-with-more-than-one-voice.
 But in my file, autochange is only applied to the top voice, and it drags
the other voice with it to the up staff.

What am I doing wrong?

\version 2.18.2

scaleRH = \relative c' {c d e f g a b c c b a g f e d c
g a b c d e fis g g fis e d c b a g}

scaleLH = \relative c {c d e f g a b c c b a g f e d c 
g a b c d e fis g g fis e d c b a g}


\score {
   \new PianoStaff 

   \new Staff = up
 
   \new Voice {
   \voiceOne
   \autochange

   \scaleRH 
   
   }

   \new Voice {
   \voiceTwo
   \autochange
   \scaleLH 
   }
 

  \new Staff = down { 
  \clef bass
  }
  
}
