4. HTP and LTP channels
The Showtec Creator 2048 can treat control channels in two ways:
01) Dimmer or intensity channels work on the principle of “highest takes precedence” (HTP). If an HTP
channel is turned on at different levels in several scenes, the highest level will be output. When you
fade a scene, the HTP channels fade out with it.
02) Moving light channels work on the principle of “latest takes precedence” (LTP). The latest change
takes over from any other values, so the most recent scene to be turned on is the one which is
output. When you fade a scene, LTP channels do not normally fade (though you can make them if
you want, except for channels set to instant). They set their full values when the scene starts to fade
in, and stay there until another value is set. (You can set the value in User settings menu).
The fixture personality file tells the console which channels of a fixture are HTP channels and which are LTP
ones. Normally, only dimmer attributes are HTP, and everything else is LTP. If a fixture does not have an
intensity control channel, the gobo channel is defined as HTP to make sure that the fixture blacks out
when a scene is turned off.
5. Playing Back a Scene
To playback a scene, just move up the playback slider or press the playback button. (Make sure there
are no values in the programmer. Do this by pressing the <Clear> button, because anything in the
programmer will override the playback).
01) You can turn on multiple scenes at once.
02) All the HTP (intensity) of the scenes fade in/out as the fader is up/down. The LTP (movement)
channels will start immediately once the fader is not set to 0. (The LTP channels also run like this when
the scenes are in Mode 1 or Mode 2, unless the channels are set without fading function in the fixture
library).
03) To flash control a scene while other scenes are stopped, we can use the swop function. Press
<Swop> (indicator on), then you can flash the scenes.
6. Editing a Scene
You can edit any part of a saved scene:
01) Press <Clear> to empty the programmer.
02) Turn on the scene you want to edit, so you can see what you are doing. Turn off all the other scenes
to avoid confusion.
03) Select the fixtures you want to change, and make the changes.
04) Press <Scene>.
05) Press <Playback> button of the scene you are editing.
06) The console will tell you if the scene already exists on playback.
07) Press <A> [Merge Scene] to overwrite the existing scene. Unchanged information is not affected.
If you are in “Record by fixture” mode, all attributes of any fixture you have changed will be saved in
the scene with their current settings. If you only want to save certain attributes of a fixture, you need
to use “Record by channel” mode.
You can overwrite the existing scene entirely using <B> [Replace Scene]. This erases the playback
and saves the current programmer as a new scene.
If the scene contains shapes, and you have selected some new shapes, the original shapes in the
scene will be deleted (after a warning). To avoid it, you need to use Include function on the original
scene (see next section) to load the shapes into the programmer. Ensure that the playback fader for
the scene is set to 0 (i.e. the shape is not active) when including the scene.
