Re: Problem with unfoldRepeats and tremolos

[Mats Bengtsson]

Now I see! There is a difference between
\unfoldRepeats {\repeat tremolo 4 c8 } % Works correctly
and
\unfoldRepeats {\repeat tremolo 4 { c8 } } % Gives 16th notes!!!

As long as we don't use \unfoldRepeats, both syntax forms provide the same
output.

In version 2.8 and earlier, we used to have warning message
"warning: expect 2 elements for chord tremolo, found 1"
but it seems that this warning was removed in the revision
http://git.sv.gnu.org/gitweb/?p=lilypond.git;a=blobdiff;f=lily/chord-tremolo-engraver.cc;h=60800064c91ae4dd91b60b35827377fbbafc4694;hp=dd1c040946f78a315f2ddc8bd357770ee567221c;hb=7c578820eb536c7ff135c351932e418f5bda1c80;hpb=db735aad5ee3f02cb82f32d8b314f1bcb7ec91ff

Still, the function unfold-repeats in scm/music-functions.scm only 
checks if the
argument is a SequentialMusic or an EventChord, which is too simplistic if
the ordinary engraver doesn't distinguish between the two cases.
