In order to couple gain to distance, set the knob of gain section in the appropriate position. With the
Range control, select the lower and upper limits of the gain interval. Select with the Distance control
values of distance for which minimum and maximum gains should occur. Finally, with the Direction
switch, select whether gain should increase (Asc ascending law) or decrease (Desc descending) as
distance grows. Note that the maximal distance in the Distance control is the virtual room diagonal.
The resulting gain variation is depicted in the graph below.

Eventually, we are now going to couple quality factor Q to source speed. This last step is quite similar to
distance coupling: position Q Coupling knob to Speed, and select your appropriate ranges. A still source
has speed 0.
Example 2: Spatial Vibrato
In this current example, we are going to show that various effect parameters may be coupled to the same
trajectory attribute. Indeed, we wish here to couple both Rate and Mix vibrato parameters to source to
listener distance. In order to achieve that, you need to switch on Vibrato in Spatial Effects, and turn
rotating Coupling knobs accordingly – see the screenshot on next page. Parameter Delay is left constant
(i.e. is not coupled). To complete the settings, adjust Ranges and Distance upper and lower limits as
desired.
