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.

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. >> So you have an instrument which has to preselect a note, and >> another which much be pressed with exact timing.

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