Abstract: A string musical instrument, such as an electric guitar, comprises a plurality of sound pickups and a user interface which allows the user rapid access to various configurations of pickup settings and connections. An embodiment of the musical instrument has a user interface which allows quick access to all forty-seven possible pickup connections available in a guitar having three single-coil pickups. Another embodiment of the invention allows rapid to access a large number of possible pickup connections made possible with the use of dual coil pickups, or a combination of single-coil and dual-coil pickups on a single guitar. The different pickup configurations are accessed via user operated controls such as clear illuminated momentary buttons or touch pads. Although the musical instrument provides a large number of accessible pickup configurations, a user display makes the determination of the pickup configuration intuitive and relatively simple.

This invention intends to help reverse this trend by melding cutting-edge Western-music technologies with the noble innovations, timbre, playing techniques, and performance environments of East Asian musical instruments and traditions. East Asian stringed instruments may be fitted with separate pickups for each string for amplification, music synthesizer interfacing, separate string electronic pitch shifting, exotic signal processing, etc. Additional devices and structures, such as strain gauges, electronic strumming pads, miniature keyboards, harp, bass, or sympathetic strings, percussion impact sensors, and electronic music control switches, sliders, and buttons may be included. Video cameras may be attached to an instrument, and may be used as an instrument itself in conjunction with hand gestures.

Abstract: A lighting display master controller responds to an electronic vibration signal produced by a sensor when an instrument is played, to selectively energize light sources of different colors in a predefined pattern. The master controller energizes specific light sources of a desired color by selecting a row and column within an array. In one embodiment, the light sources are on a flexible substrate disposed within an optically transparent plastic sheath that is attached to the instrument. The pattern applied in selectively energizing light sources can be stored or transmitted in real-time from a concert controller host or personal computer. The light system can also be used to enable a student to practice and record a sequence defined by an instructor. The lights that are energized provide visual cues to the student, and the recording that is made enables the instructor to evaluate the student's performance.

Abstract: A sound determination unit previously divides sound into a low sound range for first sound, a middle sound range for second sound, and a high sound range for third sound by its frequency band. When sound information detected by the microphone is inputted to the sound determination unit, the sound determination unit determines whether the frequency band of that sound information is in the predetermined low sound range or not.

When it is in the middle sound range, a signal to operate a second vibrator is generated from a second controller. When it is in the high sound range, a signal to operate a third vibrator is generated from a third controller.

Abstract: An automatic player piano is a combination between an acoustic piano and an electronic system serving as a recorder and an automatic player; while a user is fingering a piece of music on the acoustic piano, the player strongly depresses some keys and softly depresses other keys so as to give artistic expression to the tones, and the depressed keys give rise to hammer motion at different values of hammer velocity; since the hammer velocity is proportional to the loudness of tones, the controller is expected exactly to determine the hammer velocity; the hammers travel on linear trajectories and parabolic trajectories depending upon the hammer velocity so that the controller estimates the hammer velocity by using different methods, whereby the controller can produce music data codes exactly expressing the tones to be produced.

Abstract: An electronic keyboard simulates the keyboard action of one or more acoustic pianos and/or organs. Sensors associated with each key capture the force exerted on the key, the speed of the key and the position of the key to compute an amount of force to apply in feedback to the depressed key.

Also, feedback may be determined through a lookup table containing feedback values defining a particular instrument's action. The player can switch between different instrument action definitions as desired, and may tune certain parameters to achieve a customized action.

Abstract: An electronic percussion instrument modifies the effect applied to note generated in response to a strike based on the intensity of the strike. A plurality of patches are stored in the waveform memory. Each patch includes settings for the effects applied to each pad of the instrument. The patch also includes a setting indicating whether the parameters of the effects applied to the pads are to be modified in accordance with strike intensity.

This allows the performer to easily modify the effect applied to the notes of the percussion instrument during performance.
