Sets the gradient level and offset value of the output frequency in relation to
the input voltage. These codes are displayed only when IN-06 is set to “1
(bipolar)”.
As an example, if the minimum input voltage (at V1) is set to “-2 (V)” with 10%
output ratio, and the maximum voltage is set to “-8 (V)” with an 80% output
ratio, the output frequency will vary within the range of 6–48 Hz.
