Re: Why warning: cannot end volta spanner?
David, Thanks for the explanation. Seems like a buglet in LP, but not worth while worrying about.

Simon,
Thanks - that certainly does the trick. Though why there should be a warning
message there at all is still beyond me (see the title to this thread!).
I can't find any reference in the manuals to the syntax of calling functions
like this. There's a list of functions in the Notation and Internal reference
manuals, but I can't see where it tells me how to use them, apart from the odd
example of specific functions.
Best regards,
Peter

This is what I'd like. But it compiles with the warning message. My
original questions was: why and can I get what I want without the warning?
If everything is fine except for the warning, you can use
#(ly:expect-warning "cannot end volta")
It goes on top-level, once for every instance of the warning. If a
future compilation issues fewer warnings than expected, there will be a
warning about that.

Re: Why warning: cannot end volta spanner?
David,
Not exactly! I've modded my example and am getting interesting results. In my
original music (far too long to show here) without the change to
voltaSpannerDuration the 2nd time volta spanner stretches right over the repeat
unfold (over several lines) without any error message.
My original had two nested repeat unfolds (I didn't put this into my snippet an
I didn't think it would be relevant), so I've replicated the correct structure
below. With the change to voltaSpannerDuration I get the desired effect but a
warning message. Without it there's no error message but the 2nd time volta
spanner spans 5 bars - to the end of the line. Which is different from what
happens in my original music. I can try to provide a reduced version which
displays the issue, but it'll probably take some time to work it out.

voltaSpannerDuration but this gives an error "cannot end volta spanner", which
I don't understand. Is there a way of doing this without getting an error? It
seems that LP tries to put the same number of bards into the 2nd time as the

Thank you for the MWE. If you want to show the second alternate bracket
over the "g" instead of "g a b c", then why not just move the "a b c" out
altogether? Then the \set Score.voltaSpannerDuration part isn't necessary
at all:
