For diminished and augmented chords, the lowest key
pressed is assumed to be the root.
Seventh flatted fifth chords will be recognized if either
the root or the flatted seventh is the lowest note.
Minor sixth chords will be properly detected only when
they are played in "root position".
When an octave (the root and the 8th note of its scale)
is played, only the root will be produced.
If the root and the fifth are played, the accompaniment
will use only the root and the fifth.
