Plug-in #54: Two Up H SE Two Up H SE is a transition effect designed for scratching and beat juggling. The transition displays both channels at once. When the crossfader is shifted to either edge, the corresponding channel is dimmed. When the crossfader moves from one edge to another, the previous channel's image is captured and an animation, that rotates and translates the image forward, is triggered. Parameter 1: Controls the scale of each channel.
