Copperbox revision 271.
Beaming has been re-implemented for Abc. After my two weeks practice with recursion schemes beam grouping can be done quite nicely with an unfold - if you unfold a list to a list you effectively have lookahead (just like pattern matching and direct recursion of course).
Bar splitting - to get metric subdivisions - is done with an apomorphism which makes it quite short though I can't say the code is very clear.
