beamExceptions(list)An alist of exceptions to autobeam rules that normally end on beats.
beamHalfMeasure(boolean)Whether to allow a beam to begin halfway through the measure in triple time, which could look like 6/8.
beatStructure(list)List of
baseMoments that are combined to make beats.subdivideBeams(boolean)If set, beams of mulitple stems may be subdivided by omitting a number of beamlets, dependent on
maxSubdivideInterval, between beats at mulitiples ofminSubdivideInterval.
