- Originally, we tried to have this functionality at Staff_level
-
- - by simply using the sequence of Separation-item as
- spacing-sequences. Unfortunately, this fucks up if there are
- different kinds of tuplets combined (8th and 8ths triplets combined
- made the program believe there were 1/12 th notes.).
-
-
- - We also created them from Rhythmic_column_engraver, but this has
- the problem that voices can appear and disappear at will, leaving
- lots of loose ends (the StaffSpacing don't know where to connect the
- last note of the voice on the right with)
