Each note of the pattern contains ``(pattern_id, midi_pitch, occurrence_id, morph_pitch, 
staff)``, following the format described in [4]_.

Each ``value`` field contains a dictionary with the following keys:

    * ``pattern_id``: The integer that identifies the current pattern, \
        starting from 1.
    * ``midi_pitch``: The float representing the midi pitch.
    * ``occurrence_id``: The integer that identifies the current occurrence, \
        starting from 1.
    * ``morph_pitch``: The float representing the morphological pitch.
    * ``staff``: The integer representing the staff where the current note of the \
        patter is found, starting from 0.
