Re: programming error : no heads for arpeggio found ?

[David Whipple]

I get this error also.  It comes when I use the \arpeggio without specifically assigning a chord with it.  In other words:  <c e g>\arpeggio = no error while something like 
<<  e\arpeggio \\ c\arpeggio >> will generate the error.  The output looks correct with the arpeggios being connected (when you \set 
PianoStaff.connectArpeggios = ##t).  I'd call it a bug but the output works so I haven't worried about it.

Hi all,
Thanks Mats for your prompt answer.
But I don't understand what i must do. I tried this help but no results.
Here is a new extract from my file. Is it better?
If not, I  can send the complete file.

  \version "2.8.5"

     upper = \relative c'' {
       \clef treble
       \key e \major
       \time 2/4
    <<{e16\arpeggio^\( dis\) cis^.^\( b^.\) b8 b16^.^\( cis^.\)}
\\{a4\arpeggio b16_\( a\) gis_._\( fis_._\)}>>
}

     lower = \relative c {
       \clef treble
       \key e \major
       \time 2/4
    <b' fis'>4._\( dis8\)
}

     \score {
       \context PianoStaff <<
    \set PianoStaff.connectArpeggios = ##t
   \set PianoStaff.instrument = \markup{ \fontsize #6 {"13. "} \hspace #1.0
}
         \context Staff=upper \upper
         \context Staff=lower <<
           \clef bass
           \lower
         >>

       >>
       \layout { }
}
