Hi,
please always try to boil down your code to a minimal example, like:
\version "2.19.15"
\repeat tremolo 8 { b'16 b'' }
Anyway, part of the problem are the Stems.
Yes, whole notes _do_ have a Stem in LilyPond. Look at the terminal-output of:
\relative c'' {
\override Stem.after-line-breaking =
#(lambda (grob) (newline) (format #t "\n\tStem found: ~a\n" grob))
c1
}
In your use-case you can deal with it, setting stem-direction explecitely.
Though, overrides for 'gap and 'positions of Beam may trigger more
warnings, which can be surpressed as shown below:
\version "2.19.15"
%% The overrides for 'gap _and_ 'positions, both may trigger a warning,
%% depending on the used values
%% Uncomment one or both of the following lines to get rid of it
% #(ly:expect-warning (_ "weird stem size, check for narrow beams"))
% #(ly:expect-warning (_ "weird stem size, check for narrow beams"))
{
\override Beam.gap = #1.5 % a value of 2 will cause warnings
\override Beam.positions = #'(1.6 . 2.8)
\repeat tremolo 8 { \stemUp b'16 \stemDown b'' \stemNeutral }
}
HTH,
Harm
