XOR Gate is the brainchild of Heinrich Mueller, one half of Drexciya and Dopplereffekt. In linguistic or electronic logic, the XOR Gate designates a device, digital or grammatical, which outputs a value only when two di ering inputs are fed into it. This can be summed up with the formula ‘one or the other but not neither, nor both.’ A conic section is a shape created as a plane intersects a cone. This can result in di erent figures such as a circle, an ellipse, a parabola or a hyperbola. Conic Sections is here composed of eight themes, or shapes, over which waveform and synthesis entirely merge with human emotions. The line is blurred. These eight themes are intertwined, forming one long musical string. The line is forever blurred.
