FW: beat divisions and compound meter

[Carl Sorensen]

Forwarding to list, which I apparently didn't do before.

    Here's the whole thing in a MWE:
    
    ---------------------------------
    \version "2.19.80"
    
    
    beambreakOn = {
      \set subdivideBeams = ##t
      \set baseMoment = #(ly:make-moment 1/8)
      \set beatStructure = #'(2 2 2 2)
    }
    
    beambreakOff = {
      \set subdivideBeams = ##f
      \set baseMoment = #(ly:make-moment 1/8)
      \set beatStructure = #'(2 2 2 2)
    }
    
    
    \relative c' {
      \time 4/8
      
      %1
      \beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata < a, 
cis e >32 < a cis e > \beambreakOff
      
      | %2
      \compoundMeter #'((4 3 16))
      < f' a c >8 < d fis a >16 < f a c > < g b d >8\fermata < d fis a >16
      
      | %3
      \time 4/8
      \beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata < a, 
cis e >32 < a cis e > \beambreakOff
    }
    ---------------------------------
    
    Is there a command I can insert after the first measure to allow the 
\compoundMeter command to reset beam divisions as intended?
    Here's my code:
    
    \version "2.19.80"
    
    
    beambreakOn = {
      \set subdivideBeams = ##t
      \set baseMoment = #(ly:make-moment 1/8)
      \set beatStructure = #'(2 2 2 2)
    }
    
    beambreakOff = {
      \set subdivideBeams = ##f
      \set baseMoment = #(ly:make-moment 1/8)
      \set beatStructure = #'(2 2 2 2)
    }
    
    compoundBeaming = {
      \set subdivideBeams = ##f
      \set baseMoment = #(ly:make-moment 1/16)
      \set beatStructure=#'(4 3)
    }
    
    
    \relative c' {
      \time 4/8
    
      %1
    \beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata <a, 
cis e >32 < a cis e > \beambreakOff
    
      | %2
      %\time 7/16
      \compoundMeter #'((4 3 16))
      \compoundBeaming
      < f' a c >8 < d fis a >16 < f a c > < g b d >8\fermata < d fis a >16
      
    
      | %3
      \time 4/8
    \beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata <a, 
cis e >32 < a cis e >
     \beambreakOff
    }
    
    
    The beat pattern is not set automatically, but the beaming is handled 
automatically once the beat patter in set,
    at least as far as I can see.
    
    HTH,
