want to multiply the distance between the region’s values and the threshold value. You
can use:
•
Compression
—Expand settings less than 1.0 bring parameter values closer to the
threshold value.
•
Expansion
—Expand settings greater than 1.0 increase the distance between
parameters values and the threshold value.
Shift
Shift allows you to raise or lower all parameter values in the selected region by a
percentage of the parameter’s entire range of values. You can set Shift anywhere from
-50—which reduces the parameters’ values by 50% of the parameter’s entire range—to
50, which increases them by 50%.
GRADATION
GRADATION smooths out Automix data in order to help make transitions between
varying values sound more natural. It does this by forcing the selected Automix data to
conform to a shape, or “gradation curve,” you select.
Set Gradation Curve to the desired shape. You can select:
•
Linear
—for a flat ascending or descending shape to the selected data.
•
Exp+
—for an upward convex exponential curve to the selected data.
•
Exp-
—for a downward convex exponential curve to the selected data.
Parameter values exactly equal to the threshold value are not changed by Compression
and Expansion.
An Expand value of exactly 1.0 causes no change in the selected parameters’ values.
You can shift a value only within its parameter’s stated range. Once a parameter has
reached its minimum or maximum value, Shift has no further affect on its value.
You can use Compression/Expansion and Shift together. The selected Automix data is
compressed or expanded first, and then the Shift value is subtracted from or added to
the resulting values.
The RSS PAN Grad. MODE parameter allows you to move between RSS Pan positions
in front of you or behind you—see “RSS PAN” on Page 225.
