That did it! Thanks!!! I was quite sure I had already tried that, but
checked my RCS file and I hadn't.
I really don't understand (obvious, isn't it?) how the angle brackets

using unfoldrepeats and having different instruments, I couldn't find
an example of both together in the same .ly file. So now this will be
in the archives for the next ignoramus... :^)
