Re: setting beams for "odd" time signatures

[Markus Schneider]

Adam,

I also expected Mats' solution to work - but it doesn't. If this is by
design or random I can't say, but if you use

#(override-auto-beam-setting '(end * * * *) 3 8)
#(override-auto-beam-setting '(end * * * *) 7 8)
#(override-auto-beam-setting '(end * * * *) 10 8)

and

\time 12/8
\set beatLength = #(ly:make-moment 1 16)

in conjunction it will work as expected.

See full example below.
