Classical Mode adds a further level of harmonic organization to the piece. If Classical Mode is checked, notes in your piece will be altered to fit the current chord (by default C Major).

The durations of notes in the melody are not affected, and the inner melodic contours of the motives are approximately maintained. Notes of one sixteenth duration are unaffected by the Harmony Line.

While Classical Mode considerably reduces the level of dissonance in a piece, its effect can become less interesting after a time. In order to remedy this, a high degree of harmonic control and interest may be attained by manipulating the Harmony Line.
