Effects
LTP channels may be used to preserve an effect in certain channels
regardless of levels in the effect. Also, multiple effects can run
simultaneously, and other looks can be provided concurrently with
effects.
These features are available in the console when you use LTP channels.
When an effect cue is sandwiched between two other cues, LTP channel
levels in the effect cue are ignored when determining which control takes
precedence. A cue that runs after an effect skips over the previous effect
cue to determine what happens to levels. If there is a move in the current
cue with respect to the same channel in the cue before the effect, the
channel fades in the current cue and is “stolen” from the effect. If no
move, the channel continues in the effect.
Blocking cue
A cue running in the background ends when its last fading channel has
finished or a background override ends the cue prematurely. Sometimes,
however, you would like to end a background cue prematurely.
The way to do that is to follow the background cue with a blocking cue.
A blocking cue does to timing what an allfade cue does to level. As soon
as an allfade cue is started, all unused channels are forced to zero.
Similarly, when a blocking cue starts, all channels running in background
cues are faded to completion in the blocking cue’s timing. A blocking cue
ends all background cues.
Aside from its initial effect on background cues, the blocking cue runs
from that point on just like any other cue, including the possibility that it
could be forced to the background itself by the next cue.
