The 8 circles of the logo on the left correspond with the 8 audio chain channels on the right. In addition, there are some pragmatic controls for visual elements such width of the "disc circles" and the scale of the visuals, and global audio controls, as well as monitors for the state of each channel. There is a big fat RESET bang that sends a 'RESET' signal throughout the system to restore sensible defaults, and a GO! button on each ramp. On completion the 1st ramp bangs the 2nd ramp, a simple form of sequencing.
In the next image we examine the top-level patch in more detail.
