If the key signature is missing from the score, it suggests
the scale it's based on wasn't scaled to give the new
tuning. So the correct alteration doesn't exist.
Yes, there's a key signature in MIDI. It looks something
like FF5902FF for F major (1 flat) or FF590201 for G major
(1 sharp).

That's a shame. I'm way behind in my versions, but I
didn't think anything that was working was going to break.
This code for key signatures has always worked:
\set Staff.keySignature = #(scale-key-sig '((6 .
-1/2)) tuning)
Without the function, something like
\set Staff.keySignature = #'((6 . -12/31))
It avoids trying to send the key signature to MIDI.
