Structure: attributes that contains lists of Note and Instrument objects. Time: attributes that contains lists of Bar, Beat and Subdivision objects.

A MIDI file can contain time signature changes, so each Beat objects are equivalent to the Bar they belong to. Ex.: a 2/4 time signature will contain 2 beats = 2 quarter notes whereas a 3/8 bar will contain 3 beats = 3 eight notes.
