huh, I understand less and less.  I'll try this example;
my meantone tests are not crashing, they produce
correct MIDI (at least it sounds correct - I didn't think
MIDI has a concept of key signature); the signature
is missing from the score, though.

Graham sent me an example, but 2.13.51 couldn't
compile it.  I want to work on that too.
