Hi Nick,

thanks for testing.

The problem is, that my code inserts the \stopTextSpan-equivalent
before the last of the music-elements. In your example, _before_
starting \times and not before the last note of \times.

Currently I can't see any possibility to fix that code, with reasonable effort.

Perhaps I should delete this snippet.


Best,
