Fixture channel type determines HTP or LTP priority: Intensity types follow HTP, all others follow LTP
In QLC+‘s fixture definition editor, each channel’s Type implicitly determines HTP or LTP precedence. Intensity, Red, Green, Blue, Cyan, Magenta, Yellow, White, Amber, UV, Lime, and Indigo follow HTP (highest value wins). All other types — Pan, Tilt, Gobo, Color, Speed, Shutter, Beam, Prism, Effect, Maintenance — follow LTP (latest value wins). This reflects physical reality: you always want the brightest intensity source to dominate, but want the most recent command to govern where a head points. Assigning the wrong type causes unexpected conflicts.
Examples
Dimmer, Red, Blue channels → HTP. Pan, Tilt, Gobo, Strobe speed channels → LTP. A ‘Master Dimmer’ → Intensity (HTP); ‘Strobe Rate’ → Speed (LTP).
Assessment
A fixture has a ‘global dimmer intensity’ channel and a ‘color wheel position’ channel. Which type should each be assigned, and what priority rule results?
