taken from the pearl 2004 manual:

 

6.1 What are HTP and LTP channels?

If two or more memories are turned on together, or if you fade out a memory, the Pearl needs to know how to output the levels from the memories. To make this work, the Pearl treats channels which control intensity differently from other moving light control channels.

 

Dimmer or intensity channels work on the principle of “highest takes precedence” (HTP). This means that if the same HTP channel is turned on at different levels in several memories, the highest level will be output. When you fade a memory, the HTP channels fade out.

 

Moving light channels work on the principle of “latest takes precedence” (LTP). This means that the latest change takes over from any other values, so the most recent memory to be turned on is the one which is output. When you fade in a memory, LTP channels do not fade, but come on at their full values, and stay there until another value is set. This is important, because when you fade in a memory you normally just want the fixtures to fade up in their proper position, colour and Playback faders and roller gobo, you don’t want the fixtures moving and changing colour (though you can do this if you need to).

 

The fixture personality file tells the Pearl which channels of a fixture are HTP and which are LTP. Normally, only dimmer attributes are HTP, and everything else is LTP.
