Well, then… that explains it, since the visuals were therefore not critical.

It doesn’t properly handle key signature changes, in particular those which are 
abstracted (but maybe even those which are inline?). See for example the thread 
at <http://lists.gnu.org/archive/html/lilypond-user/2015-01/msg00201.html>. 
That is one of the main requirements in “all of the requirements” — and perhaps 
the only one that isn’t handled well by any method I’ve seen to date. Your 
interesting work on the “smartkey” function (back in 2013: 
http://lists.gnu.org/archive/html/lilypond-user/2013-10/msg00180.html) gave me 
hope, but then wasn’t fully sufficient to solve the whole instrument-switching 
problem once and for all.

But hitting the ‘reset’ button… Perhaps by now, with all the recent 
improvements in the codebase, there is a single way to make multi-instrumental 
parts easy to code and output (in both transposed and concert versions), 
without being forced to break the music into independent variables, manually 
add redundant key changes, etc.?

Best,
Kieren.
