In the left and right corners of the Seaboard Block’s upper ribbon are buttons
that switch octaves to extend the range of the controller. Pressing the right
octave shift button once raises the Seaboard Block’s pitch by an octave, and
pressing the left octave shift button once lowers the Seaboard Block’s pitch by
an octave. The current octave shift in NOISE can be any one of 6 octaves,
giving a single Seaboard Block a possible range of seven octaves (84 notes).
