Hi Gianmaria,

this is surely not 2.18.2-code ;)
With 2.21.0 the construct
\music ~ \music
will add the Tie to the last event of first \music, if suitable. But
this last element is removed by \keepWithTag #'testOne, thus no Tie.

The following would work, although I guess it's not what you want:

{ \keepWithTag #'testOne \music ~ \keepWithTag #'testOne \music }


Cheers,
