Transposing the Octave
If you need to raise or lower the keyboard note range
for the Voice, you can use the OCTAVE[UP] button
to raise the range by an octave and the OCTAVE
[DOWN] button to lower it by an octave. You can
shift the note range by up to three octaves in either
direction. The current octave setting is shown in the
left corner of the display while the OCTAVE [UP] or
[DOWN] button is being held down.
For instance, if you press the OCTAVE [UP] button
twice (+2), pressing note C3 on the keyboard will
actually play note C5 (i.e., the note you play is
shifted up two octaves). To return to the standard
octave range (0), press the OCTAVE [UP] and
[DOWN] buttons simultaneously.
OCTAVE
DOWN UP
n If you set the octave beyond the limits of the Voice's
note range, notes played outside of the range will
sound one octave higher or lower than normal.
n The OCTAVE [UP] and [DOWN] buttons may not
function if the "Note Shift" parameter (pages 61,
74) in Voice Edit Mode, and also the "Kbd Trans
(Keyboard Transpose)" parameter (page 90) in the
Utility Mode have been set to shift the range.
n You can also use the OCTAVE [UP] and[DOWN]
buttons in Multi Play Mode.
