It certainly would be nice to have only things that are relevant, specific,
useful, and consistent!

You’ll see the problem in the snippet below (n.b. requires OLL to compile): the
key signatures (included in a separate variable that is simultaneous-ed in with
the note variable when the score is built) are not being transposed according
to the instrument that begins to play at that exact moment [see first score];
but if the key change is delayed, the key signatures are transposed properly
[see second score].
There’s probably a really simple fix in the auto-transpose framework code that
will eliminate this issue, but it’s definitely above my current pay grade!
Cheers,
Kieren.
