Editing Artist Help:Fixture Control Chases

The parameters of the fixtures contained within a group can be made to chase. If you have for example, a group of 8 scans, you can make the dimmers chase in various patterns. You can have more than one chase running in each fixture group, so you could also have a chase on the tilt, the pan and the dimmer.  

=== The Parameter List ===

The list displays the parameters in the currently active fixture group.

|-
| Dark chase || Inverse of 'Chase'. The injector sets the number of dark channels.

|-
| In and Out || Two chase opposing chase running towards one another. The number of chasing channels in each direction are set by the 'Injector'.

|-
| Injector || specify the injection number. A injector of 1 would produce a normal chase, 2 would make a two channel chase etc.
|}

=== Matrix ===

The matrix combo box allows you define the array that the selected chase pattern is applied to. For example, a 2 x 4 matrix with a chase running will consist of two 4 channel chases.

The Flip function rotates the matrix through 90º.

=== Soft Start ===

If this button is checked then the chase starts with the first step at a zero level and fades in. If it is not, the first step snaps in.

=== Masking Fixtures ===

You can exclude a fixture from an active chase by right-clicking on it in the Fixtures view and selecting Chase Mask or by holding the Control key while clicking on it.

=== Editing chase parameters within a Scene/Cue ===

When a scene or cue is accessing a chase, open the chase dialog and click the find button until the chase whose parameters are to be altered is displayed. It will appear in the 'On' column as 'Sub'. Select the row and then adjust the parameters as required. To store the changes click 'Store >>" which will save the changes to the cue or scene whose name appears in the adjacent text box.
