Re: custom compound time signature

[diekunstderfuge]

Thank you so much! This code worked perfectly. You were of course absolutely
right about the context for \numericTimeSignature...I can't believe I didn't
spot that myself!

I have not worked with Scheme before and I would like to start learning how
to write advanced tweaks for Lilypond as well as functions to automate some
of the writing of music expressions. So far I've noticed on my own some
differences (such as #(define... for music expression functions, but
#(lambda... for dealing with grobs) but I haven't found a good resource to
help me learn more about these details. I'm a musician/musicologist with
only a little programming experience.

I'm still using 2.12.3 because that is what the Lilypond download site lists
as the latest stable version for Windows. Where can I find 2.14.2, and how
could I install it while keeping 2.12.3 in case I need to fall back to the
earlier version?

Many thanks!
