Capability Editor

With the Capability Editor you can define a value range for a certain functionality provided by a fixture channel. For example, if values 0-15 produce a white colour capability, you might put:

Controls

Min The minimum value of the capability
Max The maximum value of the capability
Description The name or description of the capability. Don't be too elaborate, just a few words will do.

Click & Go capability

The Click & Go functionality for a channel starts from the Capability Editor.
When a channels group is set to Gobo, Colour or Effect, it is possible to assign the colour or a picture that will be displayed by Click & Go on Scene Editor, Simple Desk and Virtual Console Slider.
This allows very quick visual feedback, and will avoid you having to remember the meaning of each range of values.
When a channel can support Click & Go, some additional controls will appear on the right side of the Capability Editor, displaying 3 butons and a preview box. Here's the meaning of each one:

Picture ... By clicking on this button you can select a picture for this range of values, to be displayed by Click & Go for visual association and quick access
Colour By clicking on this button you can select the first colour for this range of values. When the first colour is set, the 'Second colour' button will be enabled. See below.
Second colour When clicking on this button you can select a second colour for those cases where a fixture supports it. For example, this is quite useful for moving heads whose colour wheels support intermediate positions.
