Abstract:
A system and method for correction of finger positions for an electronic musical instrument. By adding a correction step in the direction of a nearest grid value, the system can perform correction in a manner that allows for gradual position correction while maintaining a vibrato or glissando shape that is similar to vibrato or glissando shape of the actual finger positions over time. The system and method may be used for pitch correction for a continuous-pitch electronic musical instrument.
Abstract:
A system for producing music from a stringed musical instrument includes a sensor/actuating transducer arrangement coupled to each or all of one or a plurality of the tensioned strings and supervisory system that governs one or more motion controllers associated with the transducer to affect the string vibration through at least one actuator transducer coupled to the string(s) in accordance with technique commands issued by the player of the instrument, the technique commands being recognized by processes in the supervisor from among characteristics of signal features extracted by further processes continuously analyzing the motional behavior of one or more strings.
Abstract:
The invention is a method and system for applying more effects to voices in an input sound than is capable of being supported by a sound processor. Aspects of the invention include identifying at least one of the voices of the input sound as a voice bus channel; and during processing of the input sound, inputting and adding sound that was mixed from outputs of previously processed voices to the voice bus channel to create a summed result. An effect specified for the voice bus channel is then applied to the summed result, thereby applying the effect to the previous the process voices.
Abstract:
A musical tone control apparatus has grips and elbow angle detectors, in which the grips are hand held and provided with push-button switches and an actuator, both of which are operated by fingers to generate musical tone control data having variations of musical tone. While the elbow angle detectors are provided with an angle detector for measuring an angle of the elbow during a performance, and generating musical tone control data with the variations corresponding to the angle of the elbow. Each variation is determined by function assignments which correspond to each of the fingers and elbows. The function assignments are preloaded in a memory device, such as a depth of vibrato, a speed of tremolo, a range of pitch-bend, and the like. Accordingly, the musical tone control apparatus transfers musical tone control data having variations to a musical tone generating apparatus to produce a musical tone from a speaker.
Abstract:
An electronic musical instrument includes a tone generator, a manipulator for defining a manipulation region and for performing manipulation within the manipulation region. The manipulator has a first detector which detects serial position data on the basis of positions of performance manipulation within the manipulation region, and a second detector which generates changing-degree data of a locus which is constituted by the serial position data. The tone generator generates musical tone with effect in accordance with the changing-degree data to thereby impart various effect such as vibrato with ease.
Abstract:
An electronic musical instrument employs a novel technique to produce a musical sound. A major part of a musical sound producing section of the electronic musical instrument is constructed by digital circuitry which is well adapted for an LSI fabrication. The electronic musical instrument comprises a volume control means to digitally perform a volume control to increase or decrease a performance volume, a period counting means to count one cycle of a musical sound wave by a plurality of counting steps in order to form a musical sound wave under digital control, a period control means to control the period counting means in accordance with the scale represented by a depressed performance key, and a means to instruct the rise and the fall of a musical sound wave by a value which is an integral multiple of a control value of the volume control means, for each block including a predetermined number of counting steps.

Abstract:
Musical tone signals in electrical form are applied to a plurality of formant filters which are tuned dynamically by player operated controls and by electronically generated control signals. Control signal shaping networks or special potentiometer controls are switched in a number of ways to produce different formant frequency response patterns including one similar to that of the human vocal tract producing dipthongs. The disclosure includes filters which are responsive in tuning to a control voltage and filters in which both inductive and capacitive components are varied for tuning so a nearly constant Q is maintained over wide tuning ranges.
