\articulate problem

[Patrick or Cynthia Karl]

The following snippet shows several problems:

\version "2.19.15"

\include "articulate.ly"

S = \relative b' {

  \set Staff.instrumentName = "S"

  \clef treble

  c4 c16\prall e r8 r r r r

  c4 c c c

}

A = \relative c'' {

  \set Staff.instrumentName = "A"

  \clef treble

  c4 c c c

  c4 c c c

}

\score {

 \unfoldRepeats \articulate

  \new ChoirStaff <<

    \new Staff { \S }

    \new Staff { \A }

  >>

  \layout { }

  \midi { }

}

The chief problem is that it generates a defective midi file in that there is a eighth note shift in the 2nd measure between the two systems.

This shift can also be seen in the engraved file.

Another problem is the representation of the \prall in the engraved file, which includes a quarter note head without a stem and a whole note.

The final problem is the huge number of warnings and programming error messages in the log file.  These include:

      * two instances of:

Articulate_problem.ly:7:20: warning: adding note head to incompatible stem (type = 1/1)

      c4 c16\prall 

                   e r8 r r r r

   *  fourteen instances of:  programming error: insane spring distance requested, ignoring it

   *  one instance of:        programming error: insane spring min_distance requested, ignoring it

   *  one instance of:        programming error: insane spring constant

   *  seventeen instances of:   continuing, cross fingers

   *  one instance of:        programming error:  going back in MIDI time
