Please note that the 8*1/2 duration (i.e. looks like an eighth, but takes time 
like a 16th) also applies to the next note, since it is not explicitly changed! 
Basically, this example is giving half of the a'' at the end of the glissando 
to the hidden note.

In your example you are explicitly setting the duration of the following note 
to an eight, without scaling it to a 16th... That's the problem.

You would use the exact same code as above. the 1/2 does not come from the time 
sig. Rather, it allows you to use half of the time of that not for another, 
hidden note before it. The 1/2 for this and the hidden note simply ensures that 
they take exactly the same time as the visible eighth note sggests.
