CHASE/SCENES mode
This control mode allows you to store a scène or a chase of 24 channels in every Preset B fader. The


Scene/Chase:
A scène is 1 setting of the intensity of the 24 channels. This is in fact a chase with 1 scene. Only this setting
will be showed constantly.
A chase contains multiple scenes and each scene contains the intensity for 24 channels. The scenes will be
showed one by one (and you can set the speed/fade time).
You have 4 pages with each 12 PRESET B faders which each can contain a scene or a chase. So you can
store 48 chases/scenes.
