From
<URL:http://www.lilypond.org/doc/v2.16/Documentation/notation/writing-pitches#relative-octave-entry>:
If no octave changing mark is used on a pitch, its octave is
calculated so that the interval with the previous note is less than
a fifth. This interval is determined without considering
accidentals.
_Without_ _considering_ _accidentals_. This is stressed again later:
As explained above, the octave of pitches is calculated only with
the note names, regardless of any alterations. Therefore, an
E-double-sharp following a B will be placed higher, while an
F-double-flat will be placed lower. In other words, a
double-augmented fourth is considered a smaller interval than a
double-diminished fifth, regardless of the number of semitones that
each interval contains.
That means that you _can't_ figure out relative mode by listening to the
Midi. The note _names_ are what determines the intervals here, not the
audible intervals.
