OCTAVE CHANGE
Transposition, Tuning, & Octave Change
This function allows the LEFT, RIGHT 1, RIGHT 2, and LEAD voices to be independently transposed up or down
by one octave.
The LEFT, R1, R2, and LEAD LCD buttons directly
set the octave of the corresponding voice. Pressing one of
these buttons changes the corresponding octave setting to
“
+1”, “–1”, and then “0”, in sequence. “+1” shifts the
voice up one octave “ –1” shifts the voice down one
octave, and “ 0” sets the voice to its normal octave.
NOTES
• These parameters are also available in the F1 VOICE PART
function display — page 101.
• Some voices may suddenly shift octaves when played at the
extreme ends of the keyboard if they are set to a lower or higher
octave than normal. This can also occur when the PITCH BEND
wheel is used on extremely low or high notes.
• If you change the transpose, octave change, or tuning settings
while playing one or more notes on the keyboard, the new octave
change settings will take effect from the next notes played while
tune and transpose settings take effect immediately.
