Hi Davide,
many thanks for testing.
Though, `autoSplitChord` is meant ot be a tool applied to chords, i.e.
event-chords.
All of:
\chordmode { c:/g }
{ }
<<
{c4 d e f}
\\
{c' d' e' f'}
>>
is sequential or simultaneous music.
A single note-event like c'4 is not an event-chord as well.
In all those cases `autoSplitChord` is not expected to work.
\autoSplitChord << b \\ e' \\ g'' >> works more by accident.
Below is an improved function which will simply returns the input, if
it's not an event-chord, avoiding the blank space.
\autoSplitChord << b \\ e' \\ g'' >> will stop working as well, all
notes are returned unchanged.
autoSplitChord =
#(define-music-function (stem-dir staff-names pitch chord)
((ly:dir? 0) (pair? '("up" . "down")) (ly:pitch?) ly:music?)
(_i "Split @var{chord} at optional @var{pitch}. The default of @var{pitch} is
@code{#f}, which is interpreted by the called procedure
@code{make-autosplit-chord} as @code{c'}.

The optional @var{stem-dir}, determines the direction of the stems and whether

Cross-staff ottava brackets with breaked line
Goodmorning, I'm transcribing "Scarbo" from Gaspard de la Nuit with Lilypond. There is a method for create a cross-staff ottava bracket with breaked line like this example? https://ibb.co/rwLwd19 Thanks for your attention!
getting an extra beam, not sure why
I have a piece in 5/8 which includes a passage of 32nd notes. I would like
to have it so that the beams are subdivided. I would like the first 10
notes beamed with subdivisions of 4 and then 6 32nd notes, then a repeat of
that for the second 10.
Here is what I tried to do to make that happen.
\version "2.20.0"
\score { << \new Staff << {
\time 5/8
\set baseMoment = #(ly:make-moment 1 64)
\set beatStructure = #'( 8 12 8 12 )
\set subdivideBeams = ##t
b32[ b b b b b b b b b] b32[ b b b b b b b b b]
} >> >> }
The first set of 10 looks perfect, but the second set of 10 has a secondary
beam connecting the group of 4 to the group of 6. Can you help me out with
why this is happening and what I can do to correct it?
Making very complex cross-staff scores with Spontini-Editor
Hi everyone, as I promised in the previous post, I have added increasingly complex cross-staff notation examples to Spontini-Editor. Other examples will follow. In particular, you can find two bars from Sorabji's Sonata No. 1, where there are MANY cross-staff objects in THREE piano staves (but additional staves can be added). As you can see, the creation of such complex scores is perfectly achievable by Spontini-Editor through a standard algorithm, which makes use of cross-staff layers. You can compare the implementation of Sorabji's measures with the historical B&H edition on IMSLP: https://github.com/paolo-prete/Spontini/blob/master/examples/easy-cross-staff-example-9.svg https://imslp.org/wiki/Piano_Sonata_No.1_(Sorabji%2C_Kaikhosru_Shapurji) https://github.com/paolo-prete/Spontini/blob/master/examples/easy-cross-staff-example-9.ly Some errors of the historical edition have been intentionally corrected, others have remained intact in order to show how Spontini-Editor can also handle cross-staff scores with inconsistencies on the voices.

Automatic cross-staff chords - testing help
Hi,
Great work.
I've done some testing and found some bugs. Below the code I've tested,
attached the PDF with the result (on second page, first page are your
examples).
\autoSplitChord doesn't works with curly braces, it returns blank output
(like a blank space in the score), so it's not possible to work with:
- chordmode
- more than one chord a time
- moltiple voices
Also, \autoSplitChord doesn't works with single notes, it returns blank
space.
It accepts variables, but the result is the same.
Pippo = 1
PippoDue = \chordmode {c1:/g}
PippoTre = c1
PippoQuattro = {}
\new PianoStaff
\with { \consists #Span_stem_engraver }
<<
\new Staff = "up"

\key c\major

\autoSplitChord #UP 2 %works

split chord in two staves, split multiple voices in two staves
Hi,
I am working on accordion left-hand educational scores;
I need to split chords (entered with chordmode) in two staves, and I
also need to split multiple voices (4 or more) in two staves.
I am trying to find a way to do this automatically, because I have much
material to work with.
I have tried \autochange, but the result is not what I am searching.
Attached is a minimal example, just to have an idea.
\version "2.20.0"
% autochange example with a chord
\markup "autochange example with a chord"
\score {
\new PianoStaff
\with {instrumentName = #"1"}
\autochange
\chordmode {c:/g}
}
% autochange example with multiple voices
\markup "autochange example with multiple voices"
\score {
\new PianoStaff
\with {instrumentName = #"2"}
\autochange
<<
\autochange {e'}
\\
\autochange {g}
\\
\autochange {c'}
>>
}
% desidered result
\markup "desidered result"
\score{
\new PianoStaff
\with {instrumentName = #"3"}
\autochange
<<
\autochange
\\
\autochange {g}

Thank you and best regards.
