strange beam behavior

[Scott Russell]

Hello Lilypond folks,

I'm a (relatively) novice Lilypond user. I'm working on some non-measured (cadenza-like) material and have encountered a strange situation.

The five sixteenth notes of the 2nd figure in Line 3 ... c8 ( [ \setTextCresc d16\< c b c ) e\staccato ] ... should all be beamed together. What I'm seeing in the output is the second flag on the d facing left all by itself, then the remaining 4 sixteenths beamed together with both flags. If I remove the first (unaffected) figure, the problem resolves in the second figure, but moves to the third figure. (It all makes sense if you compile and look at the output.)

On a related note, the way this code is currently edited, line 4 looks OK. BUT, if I remove the "modified" line 3, you'll see the same strange beam behavior in the "fis16 [ ( g" sixteenth notes in the middle of the line.

Any ideas on how to make these beamings work?

Thanks!

% ORIGINAL - doesn't work - first figure OK, second figure wrong, third and fourth figures OK.

\bar "" \break

% MODIFIED - removed first figure - now it moves the error into the next figure - why?

c8 ( [ \setTextCresc d16\< c b c ) e\staccato ] d8 ( [ e16 d cis d ) f\staccato ] e8 \( [ f!16 e dis e \) g\staccato ] f!1\f \breathe
