Re: elegant compound time signatures

I'm not familiar with the whole rhythmic requirement but this seems to 
reproduce the second bar of the snippet correctly.  Unfortunately 
subdivideBeams still must be turned on/off manually if the (2+2) pattern is 
required.  The key is setting the beatLength to 8 rather than the 16 derived 
from the time signature.

(As I'm currently reviewing the Rhythms section of the Notation Reference 
this might be a useful example of using beatLength)

Trevor

\version "2.11.62"
\relative c'' {
 \time 11/16
 #(override-auto-beam-setting '(end 1 16 11 16)  4 16)
 #(override-auto-beam-setting '(end 1 16 11 16)  7 16)
 \set beatLength = #(ly:make-moment 1 8)
 c16 b a g
 g f a
 g8 f16 e

 \set subdivideBeams = ##t
 c'16 b a g
 \unset subdivideBeams
 g f a
 g8 f16 e
}
