When I attempt to change the "direction" property of a slur, whether that
is with \tweak or \override, I cannot set the direction to neutral (0). UP
(1) and DOWN (-1) work fine, but when setting to 0, I get the following
error:
"Assertion failed: d, file
/home/lily/lilypond-2.24.0/release/binaries/mingw/lilypond/lilypond-2.24.0/flower/include/drul-array.hh,
line 56
Exited with return code 3."
This is necessary for a function I am creating; Slur.direction has already
been set to UP or DOWN earlier in the document, and I need to temporarily
set it to neutral while also changing its color. (\once \slurNeutral is not
practical here)
Below is example code that generates the error:
\version "2.24"
\language "english"
{ c' d' \tweak Slur.direction #0 ( e' ) c' }
Any suggestions?
Thanks,
