Hi. The code below results in a gap between the last notes.
There is enough room below "d" (bottom staff) to draw the sharp of
"fis".
P.S.: Concerning to "beams should not collide with accidentals"
issue (#76), I
think the clashes are a awful bug, since a score with collisions is
hard to
read. One takes effort and time to figure out if a black spot is a
sharp or a
natural, if the duration is eight or 16th note, and so on.
\version "2.13.7"
\paper{ ragged-right=##t }
{
<< \relative c'' {d16 c a d,} \\
\new Staff
\relative c {\clef bass c!16 a d fis, } >>
}
