the operator wants to show external effects like pyrotechnics, video, or spotlights.
Board Channel
On a console a channel may only be represented by a number which is
assigned by the system to control any number of physical dimmers, color
scrollers, or other devices. Generally a control channel represents the smallest
easily divisible set of controls a designer has over groups of lighting instruments.
A soft patch or pin patch is used to assign dimmers or groups of dimmers to
individual control channels.
Bump Button

over lighting control channels. On some consoles bump buttons can be put into
solo mode where all channels except those controlled by the bump button go
out.

lighting instruments, and can be manipulated by rate, intensity, and fadetime.
