Add
Use the Add parameter to change the range of CC values sent by the controller (in
combination with the Scale and Curve parameters). The Add parameter adds or subtracts
from the CC values sent, changing the lowest and highest values sent by the controller. MIDI
controllers are limited to sending values from 0-127, even if the Scale and Add parameters
are set to produce values outside of this range.
By default, each continuous controller sends CC values 0-127, 0 at its lowest position, and
127 at its highest position. These values can be added to the value of the Add parameter in
order to change the range of CC values. For example:
When when Add is set to 0 (with Scale set to 100% and Curve set to Linear), the controller
sends CC values 0-127, 0 at its lowest position, and 127 at its highest position.
When when Add is set to 64 (with Scale set to 100% and Curve set to Linear), the controller
sends CC values 64-127, 64 at its lowest position, and 127 at its middle position through its
highest position.
When Scale is set to 50%, the controller sends CC values 0-63, 0 at its lowest position, and
63 at its highest position. With the Add parameter set to 64, the controller sends CC values
64-127, 64 at its lowest position, and 127 at its highest position.
When Scale is set to 200%, the controller sends CC values 0-127, 0 at its lowest position,
and 127 at its middle position through its highest position. With the Add parameter set to
64, the controller sends CC values 64-127, 64 at its lowest position, and 127 at its middle
position through its highest position.
Curve
The Curve parameter lets you apply different curves to the controller values, in order to make
the controller more or less responsive in certain ranges of controller positions, or to distribute
high and low values over different ranges of controller positions.
The Linear setting distributes CC values 0-127 evenly over the range of the controller, with
0 at its lowest position, and 127 at its highest position. This is the default setting.
The Compress settings distributes more of CC values 0-127 over the bottom half of the
controller range, and fewer CC values over the top half of the controller range.
The Expand setting distributes more CC values 0-127 over the top half of the controller
range, and fewer CC values over the bottom half of the controller range.
The Crossfade setting is designed to be used in combination with the Rvrs Crossfade setting,
in order to smoothly crossfade between two programs on different Zones. Assign the Same
controller to Destination 7 on two Zones, and select one of these curves for the controller on
each Zone.
The Bump setting distributes CC values 0-127 to resemble a bell curve, with 0 at its lowest
and highest positions, and 127 at its middle position
