Track record function
The track record function records the levels currently displayed on the screen in
a cue, and allows you to create tracks into subsequent cues
. A track is created
by a channel whose level does not change through a series of consecutive cues
.
[Track] creates tracks by pulling channel levels from the previous cue (in Blind
mode), or by adding tracks to existing cues (in either Blind or Stage).
Cue levels are usually set live, working in Stage mode
. When you record a series
of cues, you typically record the first cue of the sequence
. The second cue is
built from the first with some of the channels changing, but many remaining the
same
. The third cue is built from the second and so on, until a major change,
such as a black out, is recorded.
This procedure results in many channels being set to a level in one cue and
staying at that level for several cues
. These tracks develop regardless of the
record function (Record or Track) you use to record the cues.
Channels levels displayed in blue on the Blind screen indicate that the channel
has moved to a new level in that cue
. This serves as a blocking level when you
create a track
. Channel levels displayed in green on the Blind screen indicate that
the recorded level is the same as in the previous cue.
The following examples demonstrate how Track works, and compare it to how
Record works
. The examples include five cues, each with five channels.
When a channel changes level from one cue to the next it is printed in
bold
on
the following pages; tracked channels are printed in regular print
. This is similar
to how Blind mode displays levels on a color monitor—channels that change
intensity are displayed in bright blue; tracked channels are displayed in green.
