Auto_beam_engraver

Generate beams based on measure characteristics and observed Stems. Uses beatLength, measureLength and measurePosition to decide when to start and stop a beam. Overriding beaming is done through Stem_engraver properties stemLeftBeamCount and stemRightBeamCount.

Properties (read)

subdivideBeams (boolean):

If set, multiple beams will be subdivided at beat positions - by only drawing one beam over the beat.

beatLength (moment):

The length of one beat in this time signature.

autoBeamSettings (list):

Specifies when automatically generated beams should begin and end. The elements have the format:

          
             function shortest-duration-in-beam time-signature
          
          where
          
              function = begin or end
              shortest-duration-in-beam = numerator denominator; eg: 1 16
              time-signature = numerator denominator, eg: 4 4
          
          unspecified or wildcard entries for duration or time-signature
          are given by * *
          
          The user can override beam begin or end time by pushing a wildcard entries
          '(begin * * * *) or '(end * * * *) resp., eg:
          
              property Voice.autoBeamSettings push #'(end * * * *) = #(make-moment 1 4)
          
          The head of the list:
              '(
          ((end * * 3 2) . ,(make-moment 1 2))
          ((end 1 16 3 2) . ,(make-moment 1 4))
          ((end 1 32 3 2) . ,(make-moment 1 8))
               ...
              )
          
          

autoBeaming (boolean):

If set to true then beams are generated automatically.
