The only difference is that midi files contain per-note velocity
information[1] which is slightly different from the expression
information contained in sheet music. [And in any event, this system
doesn't discuss velocity.]

All sheet music digitally encoded is a machine readable representation
of notes, duration and expression; it can't be anything else or it
isn't sheet music.

Midi wind instruments have existed for at least 15 years...

that can be expressed in music.
Some pirates achieved immortality by great deeds of cruelty or
derring-do. Some achieved immortality by amassing great wealth. But
the captain had long ago decided that he would, on the whole, prefer
to achieve immortality by not dying.
