Changing Pitch Reference
If you turn the VALUE knob while using the tuner, the
display shows you the setting for the AcoustiFX’s pitch
reference, which is set to 440Hz (shown as
) for the A
note above middle C. The possible range of values for this
setting is 35 to 45, which represents 435Hz to 445Hz.
When you turn the AcoustiFX on and off again, the reference
pitch is reset to 40.
While you are viewing
or editing the pitch
reference, the display
will return to pitch
indication if you do not
turn the VALUE knob
for more than two
seconds.
