Everything inside the \repeat braces is considered as a single music 
expression, so I'm not surprised if \parallelMusic does not even try to 
subdivide it.

I meant something like the following:

\parallelMusic #'(partIA partIB) { ... }
\parallelMusic #'(repeatA repeatB) { ... }
\parallelMusic #'(altIA altIB) { ... }
\parallelMusic #'(altIIA altIIB) { ... }
\parallelMusic #'(partIIA partIIB) { ... }

voiceA = {
  \partIA
  \repeat unfold 2 \repeatA
  \alternative {
    \altIA
    \altIIA
  }
  \partIIA
}
voiceB = { ... } % the same for B

It's ugly, I know - but at least it should work, and as long as you 
don't have too many repeats, it might be worth it.
