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.
