Expander Rates Menu
The Expander Rates menu provides controls for the attack and release speeds of the expanders for
each band as well as attack and release speed controls for each band’s speed governors.
• The Expander Attack speed control determines how quickly each band’s expander will rise when
the audio is in need of expansion. Faster settings will expand the audio more quickly. Using the
built-in oscilloscope to view the Undo Control Signal patch point is very helpful for adjusting attack
and release speeds as they show the gain that will be applied to the audio in each band. A detailed
explanation of how to monitor various patch points within Omnia.9/XE is provided in the Display
Settings menu of this manual.
• The Expander Release speed control adjusts how quickly the expander levels will fall once the
expansion is no longer called for. Faster settings will allow the levels to fall more quickly.
Undo also utilizes a second set of parallel expanders which look at the same input and automatically
scale the attack and release characteristics of the main expanders. These Speed Governors detect when
the main expanders have been operating at full speed for an extended period of time and will slow down
the main expanders.
• The Governor Attack speed determines how long the speed governors wait before scaling back
the speed of expanders. Faster attack speeds will cause the speed governors to slow down the
expanders more quickly.
• The Governor Release speed setting determines how quickly the speed governors give up their
influence on the main expanders.
The effect of the expander attack and release speeds are indicated by the Multiband Expander meters
in the Undo Meter window. The levels of the speed governors are indicated in the Speed Governors
window.
