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 <c' e'>
      \\
      \autochange {g}
    >>
}

Thank you and best regards.

I posted some code, with the request for testers. No reply so far.

You may be the first tester then ...

Cheers,
