In place of the term "cue", Blacktrax uses the term "chapter". This allows the lighting team to more easily differentiate between lighting cues and tracking cues while discussing design plans.
The Chapter Control Channel lets the LX operator switch Chapters using the console. The channel's DMX value between 1-255 determines the Chapter #. If set to 0, the system will be set to standby.
If more than 255 Chapters are required, Blacktrax has an optional cue "group" feature that can be enabled, named Books. Books are set as a single DMX channel, similar to Chapters.
