Re: Trouble with stem length while using cross piano staff chord engraver

[Kevin Barry]

By the way, here's how I would do the red circled section in the Takemitsu

\version "2.18.2"

rha = \relative {

  \voiceOne

  s16 s8 s4 s8 g''''16[ bes,]\laissezVibrer

}

rhb = \relative {

  <b cis e>16[ <d ees aes>8]~ q4\laissezVibrer

  \ottava #1

  \voiceTwo

  \omit TupletBracket

  \once \override Beam.positions = #'(-4 . -4)

  \tuplet 3/2 { a''16^\accent[ aes' e~ } <a, e' aes>8]

}

rhc = \relative {

  s16 s8 s4

  \hideNotes

  \override NoteColumn.ignore-collision = ##t

  a''8~ a

}

rhd = \relative {

  s16 s8 s4

  \hideNotes

  \override NoteColumn.ignore-collision = ##t

  \omit TupletNumber

  \tuplet 3/2 8 { s16 aes'''8~ } aes

}

\new Staff <<

  \cadenzaOn

  \new Voice \rha

  \new Voice \rhb

  \new Voice \rhc

  \new Voice \rhd

>>

Hi Hu,

I'm not sure I understand what you are trying to do. Bar 27 of the Takemitsu doesn't include any cross staff stems and neither do any of the examples on the github page. Can you be more specific about what exactly you want?

​Hi,

I've gone a bit farther in Rain Tree Sketch as said in a previous thread but I've stumbled upon a Lilypond issue I'm unable to deal with. When one types polyphonic music, one uses voices and Lilypond is clever enough to avoid collision with objects. When one wants to depict a chord made with two hands, one can use cross-staff stems with the corresponding engraver, as documented in this snippet and the corresponding workaround.

The context is bar 27 of Rain Tree Sketch. It's pretty messy so I cleansed it and wrote minimal examples for this issue. You can find the picture of what is to be get as well as these examples here.

Actually that problem can be reduced: is there any way to get these two items in the same time?

• something that looks like cross-staff chord;
• messy voices interleaving within two notes happen on the same beat.

I feel ill-at-ease because I don't see where I could have made a mistake. Would this be a bug? Where could I feel a bug report if so?

In addition to that, who shall I send a mail to in order to get these two snippets because merged into a single one? I think it may be more useful as they are closely related. Anyway, this large collection of snippets rocks :-)
