Track record
When you record a series of cues, you typically record the first cue, then
build the second cue from the first. Some of the channels change, but
many remain the same. The third cue is built from the second and so on.
This procedure results in many channels being set to a level in one cue
and staying at that level for several cues.
A channel whose level does not change through a series of consecutive
cues is said to “track” from cue to cue. That same sequence of
unchanged levels is also referred to as a “track.” The [Track] key in Blind
tracks into the new cue by pulling channel levels from the previous cue.
In Stage or Blind, the [Track] key adds tracks to subsequent cues.
The following examples demonstrate how Track works. They include five
cues, each with five channels. In these examples, when a channel
changes level from one cue to the next it is printed in bold; tracked
channels are printed normally. This corresponds to how Blind displays
levels – channels that rise or fall are displayed in blue or green; tracked
channels are displayed in purple.
Using record to create tracks
Use the following keystrokes in Stage to create the five cues illustrated
below (see Recording a cue in Stage, page 89). Each cue adds channels
to the previous cue.
Cue 1
Cue 2
Cue 3
Cue 4
Cue 5
[1] [Full] [Record] [1] [Enter]
[2] [Full] [Record] [2] [Enter]
[3] [Full] [Record] [3] [Enter]
[1] [At] [2][5] [4] [Full] [Record] [4] [Enter]
[1] [Thru] [4] [At] [0][0] [Record] [5] [Enter]
These keystrokes produce the results shown in the following illustration.
Notice the channel tracks that develop as a channel remains at the same
level through a number of cues. For example, channel 1 tracks from cue
1 to cue 3. 22
Chan 1 Chan 2 Chan 3 Chan 4 Chan 5
Cue 1

Cue 2 FF FF
Cue 3 FF FF FF
Cue 4 25 FF FF FF
Cue 5 00 00 00 00
22.
When a channel is not set at any level (such as channel 5 above) it is
considered tracked at clear.
