Re: Autobeaming in 3/8 time

[Mats Bengtsson]

You can use
\set Timing.beatLength = #(ly:make-moment 3 8)
but then you will get a funny looking result if you have the rhythm c8 
c16 c16 c8
for example. I'm actually not convinced that LilyPond does what it 
should in
these situations. There is a property subDivideBeams which seems to work
in some situations like
{
 \time 2/4
 b16 b b b b16 b b b
 \set subdivideBeams = ##t
 \set Score.beatLength = #(ly:make-moment 1 8)
 b16 b b b b16 b b b
}

but in 3/8 time, we get subdivided beams even if this property is set to 
false
(which it is by default).
