Correct.

This is a very interesting approach, which I will consider seriously for many 
of the applications I have. In particular, it is superior to my current 
“manually insert \transpose commands all over the place“ method. (And, p.s., I 
love the small but important abstractions you also implemented, like \KMTags — 
every reduction in duplication helps in such a complex/complicated structure!)

The one constraint/situation this might not handle is when the 
transposition/octavation happens *mid-system*. I could, of course, just accept 
that I always have to end a system and French the staves appropriately… but at 
this stage of investigation, I want to know all of my options, and the 
pros/cons of each approach.

Many thanks for this solution!
Kieren.
