10. The Shape Generator
The Shape Generator allows easy access to various preprogrammed
Shapes and Effects.
10.1 Types of Shapes
There are different categories of Shapes.
10.1.1 Cyclic and Random Shapes
Shapes can be Cyclic or Random.
A Cyclic Shape involves a repeating series of values applied to an Attribute.
The Shape Cycle is the pattern that is repeated to make the Shape.
A Random Shape does not repeat a pattern, but may, however, be
restricted to a certain range of values to create its effect. The reason for this
is that you may want a movement Shape that randomly moves the beams
around the Stage area. In this case the Shape values must be restricted to
those which keep the beams on the stage.
10.1.2 Relative and Absolute Shapes
Shapes can be Relative or Absolute.
A Relative Shape is applied in relation to the current value of an Attribute. A
Circle is an example of this, because it uses the current Pan and Tilt values
of an Attribute to define where the centre of the circle will be.
An Absolute Shape is applied regardless of the current state of the
Attribute. Most Dimmer and Iris functions behave in this manner.
10.2 To apply a Shape
All Shapes are applied in the same way.
• Turn the Key to Program. Puts you in LIVE PROGRAM MODE menu.
• Press Softbutton G [SHAPE GENERATOR]. Puts you in SHAPE
GENERATOR menu.
• Select the Fixtures you wish to apply the Shape to. Their LEDs light up.
• Press Softbutton A [PLAYBACK A SHAPE]. Softbuttons display different
Shapes available.
• Select the required Shape using the Softbuttons. Softbuttons F and G
allow you to move forwards and backwards on the different pages of
Shapes. The Shape is put into the Programmer and applied to the Selected Fixtures.
10.3 EDITING Shapes
You can customise different aspects of the Shapes. You can adjust the SIZE
(amplitude), SPEED (frequency) or SPREAD (phasing) of any Shape.
The SIZE of a Shape determines the amplitude of the function. This will
control how big a Circle is, how far a Saw is going to move or how saturated
a Rainbow is going to be.
The SPEED is obvious.
