Blackout cues and tracking
Sometimes you may add a channel to a sequence of cues that has not used that
channel yet
. For example, you may want to add a channel to all cues in a scene.
To do this, add the channel to the first cue in the sequence, and use track to
track the change through the remaining cues
.
However, the last cue in sequence may be a blackout cue
. When you track the
channel, the new channel tracks until it runs into a different recorded level
. To
assure that channels are not tracked through a blackout cue, the allfade fade
type records all unused channels in a cue at zero
. This works as a roadblock for
added tracks.
Figure 6 displays what happens when we track channel 5 through the sequence
when cue 5 is a regular crossfade cue.

Figure 6.
Channel 5 tracks through cue 5 and ruins the black out cue. If cue 5 is an allfade,
the
PSC records all unused channels at 00 percent. In the example below, an
allfade enters 00 in channel 5, cue 5
. When you track a channel through the
sequence, the new channel will not track through the blackout cue.
To select the allfade type for cue 5, enter these keystrokes:
[Blind] [Cue] [5] [type] [2]
Selects allfade fade type.
[Rec] [5] [Enter]
Rerecords cue.
