Hi,
I have problems getting autobeaming to work together with beam subdivision in
4/4 timing. I'm typesetting for the scottish snare drum and there are two
requirements that need to be fulfilled,
* beams should always start and end on even quarters (and nowhere else), and
* beams should be subdivided on eighths.
These two seem impossible to achieve simultaneously. As soon as I set
beamLength to 1/8, the beams start to break on eighths as well. Strangely it
appears to work better in other timings.
Below is a small example... if you comment out \set beatLength on line 15, you
see that the auto beaming is working as it should, but with \set beatLength it
breaks. What am I doing wrong?
thanks!
