Kompas is a three-coordinate probabilistic pattern navigator. Each coordinate has a unique travelling pace and a dedicated trigger output. The amount of probability can be adjusted manually or by external voltages. Once a coordinate has been adjusted, a new pattern is generated and looped until the next change of direction.

Unlike common probability operation, instead of filtering a pre-determined sequence, Kompas uses probability to generate new looping patterns based on the direction you choose.
