where's the slur? (4 year old question)

[Villum Sejersen]

Hello EH

Separating out the voices instead  of the chord construct seems to do 
what you want:

\version "2.15.6"
voiceA = { \slurUp e'( d') }
voiceB = { \tieUp c'~ c' }
voiceC = { \tieDown a ~ a }

\new Staff <<
  \time 2/2
  \voiceA
  \voiceB
  \voiceC
>>

Experimenting with various combinations of \tieUp / \tieDown give 
slightly different results, but the slur and  ties are attached to the 
right notes.
