Re: \repeat unfold has problems inside \repeat volta

[Valentin Petzel]

Hello Michael,

this is not a bug. You’re supposed to put the alternative after the repeat 
part not inside, so \repeat volta 2 { ... } \alternative { ... }. The way you 
have put it the \alternative ... is used as alternatives for the \repeat 
unfold (as it is placed after that one), so after the first repeat you get the 
first alternative, after the second repeat the second alternative, which is 
exactly what you are seeing here.

Cheers,
Valentin
