Clarification: it is common to beam triple 8ths in 3's and duple
8ths in 4's in the baroque period when they are mixed up together, to
indicate that the duple 8ths are structurally stases, more legato
than the triple phrases.
But, the triple 8ths are beamed in 3's and duple 8ths in 2's when a
rhythmic alternation effect is desired. Barring is there to tell the
player the structure of the music, not just as artwork!
Would you consider allowing triple-4ths to be denoted by by d''6,
triple-8ths by d''12, and so on? That way they would fit into Mudela
as naturally as duple time, including autobeaming (and presumably
auto-tying too at some point).
