Crosspoint

From English DMXCWiki

The crossing point is used when fading between two scenes or looks.
While the "fadeable" channels are crossfaded smoothly, the channels which should not be faded have to be set to a new value abruptly. This crossing point defines the level (between 0 and 100%) at which the change should happen, e.g. change the gobos at the beginning or at the end of the crossfade.
