Most analog video synthesis patches begin with horizontal and vertical ramp waveforms. These generators provide the synthesist with a method of identifying 2D coordinates on the screen. With motion controlled ramps, these 2D coordinates can be repositioned and animated at their source – causing the entire resulting video art pattern to animate.

In addition to motion control over the internal video waveforms, Scrolls presents four dedicated low frequency waveform generators. These signals are synchronous with the movement of the internal ramps, and provide ways to animate other parts of your patch in tempo with the video pattern.

Random and Journey modes provide methods for generating the illusion of autonomous entities within the space of your video composition. Watch your video pattern slowly explore around the screen at random directions, or teleport in strobing patterns of random phases. In all of these modes, the synthesist has control over a basic clock speed, which allows even chaos to step to the beat.
