4. More about Intelligent Fixtures
4.1 What are HTP and LTP Channels?
There are two basic types of Attribute - LTP, (Latest Takes Precedence or
Last takes Precedence) and HTP, (Highest Takes Precedence).
This terms refer to how different Attributes of a Fixture are recalled in the
Playback area in a Memory or Chase.
LTP Channels respond to and retain the last instruction they were given.
Colour is an example of an LTP Channel. When recalled in a Memory or
Chase, the Fixtures will all go to the colour stored in that cue when the
Playback Fader is raised. If the Fader is then lowered, the Fixtures will stay in
that colour until told to go to another one. They retain the Latest colour
instruction.
LTP Channels are generally used for everything EXCEPT Dimmers.
HTP Channels respond to the highest Playback Fader containing that
Fixture. Intensity is the only HTP Channel. If you have two Memories both
containing the same Fixture, the Fixture will take its Intensity from the highest
Playback Fader, regardless of the order in which the Memories were
activated.
To make the Fixture go to zero intensity, both Memory Playback Faders must
be taken to zero.
4.2 How HTP and LTP Channels behave in the Programmer
When you put LTP Channels into the Programmer, then CLEAR the
Programmer, the Channels are dropped from the Programmer but do not
change in value. Any Fixtures that you put to red, for example, will still be in
red, provided that they are not changed by an active Playback Fader.
When you put HTP Channels (intensities) into the Programmer and raise
them, then CLEAR the Programmer, provided that there are no Playback
Faders active with these Fixtures in them, the Channels will go to zero.
ie. The Fixtures will go out.
4.3 How HTP and LTP Channels are recorded
The following table gives details of how different channel types are recorded.
LTP Channels will ONLY record if they are in the programmer!
This means that you cannot raise a Playback Fader and directly use the LTP looks
programmed onto it! All that will record is the HTP information unless you access at
least one LTP Channel or the Intensity is changed.
To get around this, however, see Section 6.12 Using INCLUDE to program a Memory.
It should also be noted that a Memory is not made active until the
Playback Fader is taken down and raised again.
