LTP (Latest Takes Precedence) sends the most recently set value for non-intensity channels

LTP governs channels assigned to groups other than Intensity — pan, tilt, gobo, strobe speed, color wheel position. When multiple functions target the same LTP channel, the most recently activated value wins outright. An LTP channel can be moved to any value, not just the maximum. During crossfades, LTP channels often need immediate jumps (gobo changes) but sometimes benefit from gradual motion (pan/tilt). Different transition approaches can be achieved by combining Scenes in Collections.

Examples

Two scenes set a moving head’s gobo channel: Scene A selects gobo 3, Scene B selects gobo 7. Starting Scene B after Scene A causes the fixture to jump to gobo 7 (LTP).

Assessment

A fixture’s tilt channel is set to 128 by Scene A. Scene B then starts and sets tilt to 64. What value does the fixture output, and what rule governs this? How does it differ from the same scenario on a dimmer channel?

“LTP is a rule that decides what level is sent to out to a DMX universe by a channel when the channel is being controlled by more than one function or Virtual Console widget.”
