if we write repetitions on the music (and if the composer wrote them)
it means we want to repeat them. Why to add a new command to unfold them?
It's really just a short hand for editing purposes, at least as I've used it so far.
For example, when defining line breaks, rather than writing:
s4*4*4 /break
s4*4*4 /break
s4*4*4 /break
s4*4*4 /break
s4*4*4 /break
s4*4*4 /break
s4*4*4 /breakyou could write:
\repeat unfold 8 { s4*4*4 /break }
Or, for a sample of minimalist music (200 measures of 4/4), all you'd need to write is:
\repeat unfold 4*100 { c16 e d e }
\repeat unfold 4*100 { c16 e f e };-)
Obviously, when the actual printed score requires the *visual representation of repeats*, you want to use volta (or the manual equivalent).
Hope this helps! Kieren.
