Manfredi will perform a live improvisation using a no-input mixing board. Hardware outputs are fed back into the inputs, transforming the desk into an analogue synthesiser. Control over the internal processes is very far from being total – the device is in fact a semi-chaotic system, and even a slight change to a single parameter can totally subvert the totality of the audible result. The output of this paradoxical instrument is a challenge to audibility with sounds that range from the deepest bass to the most pleasantly harsh highs.
