James Lowe :
There seems to be an inconsistency with setting horizontal beams.
We have a snippet where we state that
\override Beam \#'damping = \#+inf.0
Should generate horizontal beams in all cases.
However the simple example attached shows some odd inconsistencies.
\version "2.13.40"
\relative c'' \{
\override Beam \#'damping = \#+inf.0
f16 g a b a c d g, a b a c d e f g, % all beams horizontal
f16 g a b a c d g, a b a c d e f g, % all beams horizontal
f16 g a b a c d g, a b a c d e f g, % 2nd and 4th group not
Horizontal
f16 g a b a c d g, a b a c d e f g, % 2nd and 4th group not
Horizontal
\}
\relative c'' \{
\override Beam \#'damping = \#+inf.0
f16 g a b a c d g, a b a c d e f g, \break % 4th group not
Horizontal
f16 g a b a c d g, a b a c d e f g, \break % 2nd and 4th group not
Horizontal
f16 g a b a c d g, a b a c d e f g, \break % 2nd and 4th group not
Horizontal
f16 g a b a c d g, a b a c d e f g, \break % 2nd and 4th group not
Horizontal
\}
Phil Holmes :
I'd suggest the snippet is worth sorting out, too. What do you reckon - adding
the commands
\override Beam \#'details \#'damping-direction-penalty = \#0
\override Beam \#'details \#'round-to-zero-slope = \#0
to the existing snippet, or a new one pointed to by the old one, that says "if
\override Beam \#'damping = \#+inf.0 doesn't do what you want, add the other
commands too, as shown here"?
