Level
Level blocks can be used to adjust the level (i.e. volume) of the audio signals that are passing through them. Audio signals can also be muted or unmuted within Level blocks.
The channel level may be entered numerically from a keyboard, adjusted by dragging the fader with the mouse, or nudged up and down by using the up/down arrows on the keyboard.
Initialization Dialog
The initialization dialog provides several options:
| Name | Description |
| Gang Controls | Allows all of the channels within the Level block to be adjusted simultaneously from a single set of controls. Level blocks with a “G” in the upper-right corner of the block are ganged. |
| Use Logic | Adds logic inputs to the top of the Level block. This feature allows the level of a channel to be incremented or decremented using a logic signal. |
| Use Ramping | Allows for continuous ramping of the level when incremented/decremented via a logic signal. This option is only available is “Use Logic” is enabled. |
Control Dialog Boxes for Level components can be minimized to create user control surfaces (see Customizing Component Objects ).
Logic Control
Enabling the “Use Logic” option of a Level block adds two logic inputs to the block for every audio channel. Each pair of logic outputs is labeled + and -. When one of the logic inputs receives a HIGH logic signal, it will increment (+) or decrement (-) the level of the corresponding channel. See the Logic Charts Section for more details.
The amount that the level will be incremented or decremented is controlled by the Step parameter (specified in decibels).
The Rate parameter (specified in milliseconds) controls the behavior of the block when a HIGH logic signal is continuously applied to a increment/decrement logic input for a length of time. When a HIGH logic signal is first applied, the level will immediately increment or decrement by the Step amount. Then, if the logic signal remains HIGH, after every increment of the time specified in Rate, the level will be incremented or decremented by the Step amount again.
