Re: polyphonic tuplets

[Mats Bengtsson]

If you read the section on "Explicitly instantiating voices", you will 
learn more about what the <<{...} \\ {...}>> feature does internally.
The whole tuplet probably has to be included in the same Voice context 
(which also makes sense musically) so it's rather surprising
that your example works at all even when the c2 line is removed.
