Thanks for all your answers.
Yes I understand that a Pitch bend event (like aftertouch, channel
pressure, etc) is a channel thing.
I rather thought about Lilypond being able to "look ahead|behind" like
(I imagine is working) the "Melody_Engraver" to harmonise (no pun
intended) the pitch shift up or down decision.
\language "english"
In my use case <gqs bqf> :
- the gqs is the note g pitched upward.
- the bqf is the note b pitched downward.
To homogenise the output, I think the MIDI output should transform :
<gqs bqf> → <atqf bqf>
or equivalently
<gqs bqf> → <gqs atqs>
My workaround for now is to \tag #`midiOnly.
\version "2.25.6"
\language "english"
\score {
{
<g' bf' d''> <gqs' atqs' dqs''>
<g' bf' d''> <atqf' bqf' etqf''>
<g' bf' d''> <gqs' bqf' dqs''> % < this not ok
}
\layout {}
\midi {}
}
