Re: Convert chord mode into multi-voice mode

[Frédéric]

Hi Knute,

Please let me first thank you so much for what you shared on this
topic of converting chords to multivoices. Thanks to you, I discovered
there exists a python lexer for lilypond files; this is really
awesome!

On my side, I worked in a different direction, starting from your
first script. I wanted to have a unique << { } \\ { } >> if possible
and not repeat that at each chord. Here is where I am currently. Not
yet perfect but on the following music:
\times 4/6 { r16 <re fa>-.[( <fa sib>-. <sib re>-.-> <fa sib>-. <re fa>-.)] }
I get what I expect:
\times 4/6 { r16 << {
 fa-.[( sib-. re-.-> sib-. fa-.)]
} \\ {
 re-.[( fa-. sib-.-> fa-. re-.)]
} >>
}

I am not very familiar yet with the ly library so not sure this is
really correctly done.
I see that you worked on the relative/absolute issue. I have not the
time right now to dig into that. I will certainly later but I still
wanted to share what I did.

Thanks,

F
