摘要： Disclosed is a stringed instrument with embedded DSP modeling capabilities to model an acoustic stringed instrument. The stringed instrument has a body and a plurality of strings and each of the plurality of strings is respectively coupled to a pickup to detect a vibration signal for each string. An A/D converter converts the detected vibration signal of a string into a digital string vibration signal. A DSP is located within the body of the stringed instrument to process the digital string vibration signal and to implement an acoustic modeling system to process the digital string vibration signal in order to emulate a corresponding string tone of one of a plurality of selectable acoustic stringed instruments. Acoustic modeling includes acoustic string and body modeling, microphone placement modeling, and pick-sound modeling. The emulated acoustic digital tone signal is then converted to analog form for output to an amplification device.

摘要： Synthesis of time-varying MIDI control signals useful in creating spatial perturbation, chase effects, new forms of rich musical timbre modulation, spatially-distributed timbre constructions, and other types of sonic animation. Phase staggered multi-channel MIDI-format control signals are created using one or more low frequency oscillators, each with a plurality of phase shifting elements. Control signal waveshapers may be included in the control signal synthesis chain. In an exemplary embodiment, frequency and phase parameters are adjustable, with values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals. In another exemplary embodiment, each outgoing control signal additionally may be independently assigned a selectable waveshape, which is determined by values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals.

摘要： A system for supporting performer interactions with a self-organizing chemical reaction based on monitoring and interpretation of a controllable self-organizing chemical reaction contained within a reaction vessel. The self-organizing chemical reaction initially includes two or more constituent chemical reactants which may be controllably replenished. Controller elements, responsive to reaction control signals, influence the reaction. Reaction control signals are generated by a processor in response to incoming performance signals. Selectable control-conversion algorithms may be used for this purpose, permitting an incoming performance signal to responsively influence the self-organizing chemical reaction. One or more electrodes or chemical sensors, a video camera, or other monitoring devices may be used to monitor the chemical reaction and produce outgoing control signals for controlling synthesizers, signal processing, lighting, or video synthesis. Outgoing control signals are created by interpreting monitoring signals according to selectable algorithms. Video camera signals may be displayed or projected in a visual performance environment

摘要： System and method expanding and generalizing string selection aspects of an autoharp and applying to general forms of string arrays. String vibration may be sympathetic or induced by strumming, plucking, and/or electrical drive transducers. Volume of individual vibrating strings within arrays of strings may be mechanically or electronically controlled by chord buttons or a music keyboard. Electronic control can also be made with foot switches or incoming MIDI control signals. These controls may be used individually or in combination. Keyboard keys may be provided with key-travel sensors, key-surface sensors, or other sensors for continuously controlling volumes and octave mixings of subgroups of individual strings. Incoming MIDI control signals may also be used for controlling volumes and octave mixings of subgroups of individual strings. Outgoing control signals, such as MIDI, may be generated responsive to the plucking and/or the amplitude of and harmonic structure in the ongoing vibration of individual strings.

摘要： This invention provides a signal processing and signal synthesis technique from a family of signal processing and signal synthesis techniques designed to readily interwork or be used individually in creating new forms of rich musical timbres. A real-time controllable mix of a plurality of multiple output frequency-reduced signals and the cross-products of these signals provides rich animated harmonically partitioned spectra. Mixing parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including envelope generators, low-frequency oscillators, and those derived from an original input signal, and specifically including the amplitude of an original input signal. The real-time controllable mix may have multiple outputs and be subjected to further signal processing and multiple-channel amplification. The invention may be used individually or in conjunction with other signal processing and signal synthesis techniques in creating new forms of rich musical timbres. The invention may also be used in spatially-distributed timbre construction.

摘要： Extensions and generalizations are made to the pedal steel guitar. Separate transducers provided to each string permit fixed or variable pitch and timbre modifications determined by stored program control. Variable pitch and timbre modifications may be controlled by physical controllers such as single or multi-parameter foot pedals, knee levers, and wrist controllers. Physical controllers may return to an original position or hold their position after operation. A traditional mechanical tuning changer operated by traditional foot pedals and knee levers may be included; the latter may operate physical controllers. The bar position may be sensed, and the bar may include physical controllers wirelessly linked to the instrument. A miniature keyboard and strumpad may be provided in the picking area to control synthesizers and produce MIDI output. Strumpad operation can be controlled with chord buttons, foot pedals, or other physical controller devices. Physical controllers, string vibration, and other types of control devices may also be used to generate MIDI output.

摘要： A system and method for real-time controlling of signal processors, synthesizers, musical instruments, MIDI processors, lighting, video, and special effects in performance, recording, and composition environments using images derived from tactile sensors, pressure sensor arrays, optical transducer arrays, chemical sensor arrays, body sensor arrays, and numerical computation. The invention provides for pressure sensor arrays and body sensor arrays as tactile control interfaces, for video cameras and light sensor arrays as optical transducers, for chemical sensor arrays, and for other numerical image generation from computer processing or numeric simulation. Tactile transducers may be put on instrument keys of conventional instruments, be attached to existing instruments, or be used to create entirely new instrument or controller configurations. Chemical sensor arrays and for other numerical image generation from computer processing or numeric simulation can be used to monitor or simulate natural physical phenomenon such as self-organizing process behavior or environmental conditions. Arrays of scalar or vector values are processed to extract pattern boundaries, geometric properties of pixels within the pattern boundaries (geometric center, weighted moments, etc.), and higher-level derived information (senses of rotation, segmented regions, pattern classification, syntax, grammars, sequences, etc.) which are used to create control signals for external audio, visual, and control equipment or algorithms. The invention also provides for MIDI and non-MIDI control signals.

Assignments (of control signals and behaviors to physical controller elements) may be selected, and organized in to pages and sub-pages. Activation of specific pages and subpages may be done with assignable physical controller elements. Physical controller elements and assignments may be organized in hierarchical relationships and in relationships rich in potential geometric metaphors useful for human operation.

摘要： Touch screen user interfaces configured to detect a touch gesture for controlling software applications, computers, devices, machinery, and process environments. Such user interfaces can be manipulated by users and provide a wide range of uses with computer applications, assistance to the disabled, and control of electronic devices, machines, and processes. Enhancements can include velocity and pressure sensing capabilities. The touch screen can be realized with a transparent touch sensor array positioned over a visual display. The touch screen can be configured to measure a spatial distribution profile from a touch on the touch screen and recognize gestures based on dynamics among spatial pressure distribution profiles. In an example implementation, the gesture recognition may rely solely on dynamics of shape differences between hand contact patterns and omit the use of pressure, as the shape of the spatial distribution profile does not vary much by pressure.
