Hi all
(Hopefully) a quick question about break autobeams and stem direction.
When I compile the following music, each embellishment that contains more than
one acciaccatura breaks both the autobeaming and the stem direction that I have
written in.
Bars 1-2 contain the music with embellishments
Bars 3-4 contain the same music without embellishments
If I leave bars 1-2 in, then 3-4 also break. If I comment out bars 1-2, then
bars 3-4 are correct.
What wierdness have I done in my file?
