The specification of the direction a pattern moves as the fader is pulled. A normal pattern starts small at the center and grows to the outside while a reverse pattern starts from the edge of the screen and shrinks. Normal/Reverse specifies that the pattern will grow as the fader is pulled down, and shrink as it is pushed up. This definition loses some meaning for wipes that do not have a size per-se such as a vertical bar, however, this feature still will select the direction of pattern movement.
