A process without seeds may run for hours or minutes, depending upon the start point and clock rate.
There are 3 CV outputs, two based on what is happening on each half of the circuit, one reflects the pattern created by the active cells. Each cell has a gate output.
The circuit uses CMOS chips and op amps, no microprocessors. It is a big build!
