The greater the number of control inputs, the greater the flexibility and interactive capability of the circuit. A quantitative difference in control inputs will bring about a qualitative difference in gestural expressivity. When a system is organized with sufficient complexity, it begins to manifest the qualities associated with mind and feeling. In effect, a complex circuit that is both highly responsive and interactive takes on the aura of simulated intelligence. In the domain of new formal structures, what sets the electronic arts apart from the mechanical arts is a fundamental difference between the types of instruments employed.
Mechanical instruments extend the hand, the breath, the ear, and the eye.
Electronic instruments extend the central nervous system. Advances in electronic technology have ushered in an era of experimental art structures that function internally and interact with the external world in an integrative fashion similar to the workings of the central nervous system. I also worked with smaller forms that probed the relationships between traditional acoustic instruments and electronic instruments. It is possible for an electronic instrument to rely heavily on acoustic information as its primary source of audio and control signals. In effect, it can function as an extender and expander of the acoustic phenomena.
