TODO: Remove the dependency on musical info. We should tie on the
basis of position and duration-log of the heads (not of the events).

- TODO: support sparseTies.

- TODO: melismata will fuck up now:
-
- < { c8 ~ c8 }
- { c16 c c c } >
-
- melisma is after the 2nd 8th note, but will now be signaled as
- lasting till the 3rd 16th.
