Hi list,
\tripletFeel doesn’t automatically work with \partial. IIUC,
\tripletFeet x is just a shortcut for \applySwing x #'(2 1) and one can
use \applySwingWithOffset for music with upbeat. I tried that but cannot
get it to work properly. In the following code, left and right hand are
offset against each other. What am I (or LilyPond) doing wrong?
I’m writing this to the bug list because it’s a 2.21 feature and at
least from the existing documentation I’m not able to produce correct
output which is a program or documentation bug ;)
It’s not a \partial or \applySwingWithOffset problem but a problem with
how \applySwing works: It seems to take the notes in input order instead
of sounding order/time. This means that you can have problems with
unfold repeats and simultaneous music:
\version "2.21.0"
\include "swing.ly"
% bad: all c are long, all d short
\tripletFeel 8 {
\repeat unfold 8 c'8
\repeat unfold 8 d'8
}
% good (even number of notes)
\tripletFeel 8 {
\repeat unfold 8 { c'8 d' }
}
% bad (odd number of notes):
% all c and e are long, all d short
\tripletFeel 8 {
\repeat unfold 8 { c'8 d' e' }
}
% good (even number of notes in the first staff)
\tripletFeel 8 <<
\new Staff { c'8 8 8 8 8 8 8 8 }
\new Staff { d'8 8 8 8 8 8 8 8 }
>>
% bad (odd number of notes in the first staff):
% the swing is shifted in the second staff
\tripletFeel 8 <<
\new Staff { c'8 8 8 8 8 8 8 8 8 }
\new Staff { d'8 8 8 8 8 8 8 8 8 }
>>
