Re: tie from measure with one voice to a measure with two voices

[Juan Cristóbal Cerrillo]

Hello Hwaen,

Thanks for your input.

Yes, your example is simpler, but the problem is I am working on a much more 
complex score that requires voices to be created only at specific moments.
Consider the following case. It seems odd to have to specify that a voice is 
empty for four measures in order to be able to place the tie correctly (example 
1).
I would like to be able to write it as example two, only writing voices when 
necessary.

\version "2.18.2"

%example 1
\score {
 \relative c'' {
   <<
     {
       e1~
       e~
       e~
       e~
       e2 f
     }
     \\
     {
       s1
       s
       s
       s
       c4 d e f
     }
   >>
 }
}

%example 2
\score {
 \relative c'' {
   e1~
   |
   e~
   |
   e~
   |
   e~
   |
   <<
     {
      e2 f
     }
     \\
     {
       c4 d e f
     }
   >>
 }
}
