3D music visualization process employing a novel method of real-time reconfigurable control of 3D geometry and texture, employing blended control combinations of software oscillators, computer keyboard and mouse, audio spectrum, control recordings and MIDI protocol. The method includes a programmable visual attack, decay, sustain and release (V-ADSR) transfer function applicable to all degrees of freedom of 3D output parameters, enhancing even binary control inputs with continuous and aesthetic spatio-temporal symmetries of behavior. A “Scene Nodes Graph” for authoring content acts as a hierarchical, object-oriented graphical interpreter for defining 3D models and their textures, as well as flexibly defining how the control source blend(s) are connected or “Routed” to those objects. An “Auto-Builder” simplifies Scene construction by auto-inserting and auto-routing Scene Objects. The Scene Nodes Graph also includes means for real-time modification of the control scheme structure itself, and supports direct real-time keyboard / mouse adjustment to all parameters of all input control sources and all output objects. Dynamic control schemes are also supported such as control sources modifying the Routing and parameters of other control sources. Auto-scene-creator feature allows automatic scene creation by exploiting the maximum threshold of visualizer set of variables to create a nearly infinite set of scenes. A Realtime-Network-Updater feature allows multiple local and / or remote users to simultaneously co-create scenes in real-time and effect the changes in a networked community environment where in universal variables are interactively updated in real-time thus enabling scene co-creation in a global environment. In terms of the human subjective perception, the method creates, enhances and amplifies multiple forms of both passive and interactive synesthesia. The method utilizes transfer functions providing multiple forms of applied symmetry in the control feedback process yielding an increased level of perceived visual harmony and beauty. The method enables a substantially increased number of both passive and human-interactive interpenetrating control / feedback processes that may be simultaneously employed within the same audio-visual perceptual space, while maintaining distinct recognition of each, and reducing the threshold of human ergonomic effort required to distinguish them even when so coexistent. Taken together, these novel features of the invention can be employed (by means of considered Scene content construction) to realize an increased density of “orthogonal features” in cybernetic multimedia content. This furthermore increases the maximum number of human players who can simultaneously participate in shared interactive music visualization content while each still retaining relatively clear perception of their own control / feedback parameters.

A differential switch accepts a binary control signal and its complement (which may be skewed with respect to the control signal) and latches both signals simultaneously. The latched output signals drive the control terminals of a differential switch pair which connects one of two terminals to a third terminal, depending upon the state of the control terminals. The differential switch may optionally include an inverter which complements the binary control signal, thus eliminating the need for external inversion of the control signal. The switch is particularly applicable for use in a digital to analog converter.
