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.

Chase Pattern Dialog

Chase Pattern

Chase Standard chase pattern. The number of chasing channels is set by the 'Injector'. Cascade A build-up and knock-down pattern. Unison All channels pulse on and off in unison. Alternate A flip-flop pattern. Dark chase Inverse of Chase. The injector sets the number of dark channels. Block A block chase sets an entire row of a matrix in turn. If the 'Matrix' is set to 1 X n then the channels will simply remain on. In and Out Two chases opposing chase running towards one another. The number of chasing channels in each direction is set by the 'Injector'.

Injector

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

Matrix

The matrix combo box allows you to 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.

Slider Controls

Editing chase parameters within a Scene/Cue

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.
