Subject: Break within measure in polyphony


I'm attempting to reproduce the engraving of a baroque prelude which is without 
barlines (although it appears to be in 12/8, as the bass voice has some dotted 
whole notes), and at one point the original engraving has put a line break two 
thirds of the way through a dotted half note in the bass voice. The solution 
given in the NR for forcing a line break in the middle of a measure ( 
http://www.lilypond.org/doc/v2.17/Documentation/notation/line-breaking ) 
doesn't work here - Lilypond puts a warning in the log "forced break was 
overridden by some other event, should you be using bar checks?", and ignores 
the forced break. Is there any way to force a break at this point? This example 
demonstrates what happens (I'm using 2.17.26): 

{ 
<< { 
\repeat unfold 10 { c''4 } 
\bar "" \break 
\repeat unfold 10 { c''4 } 
} 
\\ 
{ \repeat unfold 5 { c1 } 
} >> 
} 


Nick,

I'm sure someone will weigh-in with a cleverer solution but this comes to mind; 
That line breaking thing will not break in the middle of a note as you've 
discovered.  How about scaling that dotted half note by 2/3 and then following 
it with a skip after the break?  I don't know what pitch it is but something 
like:

c2.*2/3 \break s4

...might do the trick.
