摘要： A method for automatic real-time performance intonation (ARPI) of electronic, digital, or computer-based musical instruments automatically adds the intonation characteristics of a variable-intonation instrument performance to an equal-tempered chromatic instrument performance. The method emphasizes the directional lead-in quality, upwards, or downwards, of certain notes in relation to the musical context. Notes, which are musically desirable to resolve upwards in a harmonic progression receive a slightly raised pitch, and notes that generally are resolved downwards receive a slightly lowered pitch. The method identifies major thirds and major sevenths in the harmonic context and raises their pitch slightly. It identifies minor thirds and minor sevenths in the harmonic context and lowers their pitch slightly. Fourth and fifth intervals are given a pure perfect tuning and octaves are made slightly wide. All is done automatically in real-time by identifying the harmonic context from a few preceding notes.

摘要： An electronic musical instrument using continuous tone generators capable of simulating the sounds of a conventional acoustical piano. The instrument includes a gating circuit featuring a timed switch travel circuit having a double-time constant for improved control of the dynamic range from the keyboard, and a soft pedal controlling the keying voltage to produce more realistic emulation of the dynamic effects of an acoustical piano. The gating circuit produces a double-time-constant envelope of nearly harmonically related signals for a more realistic piano timbre. The tone spectrum is also controlled as a function of signal level by means of a resistor matrix feeding selected inputs of an active ladder filter, in order to reproduce timbre variation with dynamic level.

摘要： A brass keyer system for an electronic organ wherein the keyboard is multiplexed to produce a polyphonic serial data stream, which is then converted to a monophonic serial data stream containing a keydown signal in a time slot corresponding to the highest note played on the keyboard. The monophonic data stream is converted to a multiple bit binary word that is used by the tone generation and keying portion of the system to produce a rectangular wave tone corresponding in frequency to the highest depressed key and having amplitude and pulse width modulation on attack and decay so as to produce a brass tone. The monophonic serial data stream is demultiplexed by means of a recirculating delay loop which repetitively recirculates the keydown pulse for the depressed key. The number of recirculations of this pulse are counted by a first counter and the position of the pulse within the delay loop is registered by a second counter, which is synchronized with the multiplexer. The outputs of the first counter form a first binary word representative of the octave of the highest depressed key, and the outputs of the second counter represent the pitch of the tone within that octave. Data selectors connected to the binary words select the appropriate pitch from the tone generator and the appropriate octave from the outputs of a divider so as to produce a single square wave tone of the proper frequency. Modified keydown pulses function as the amplitude and pulse width modulation envelopes, which impart to the square wave tone amplitude and pulse width modulation characteristic of brass tones. The octave select binary word is decoded and used to control the amount of differentiation of the square wave tone so that the pulse width modulation will track the position on the keyboard of the depressed key.

摘要： A plurality of tone signals corresponding to one note and having the same fundamental frequency and different harmonic components are modified in amplitude according to the shape of an envelope signal generated upon key depression and having an amplitude proportional to the key depression speed. One of the amplitude-modified tone signals is clipped at a predetermined level and then mixed with another amplitude-modified tone signal. The frequency spectrum of the resultant tone signal varies with time like a piano.

摘要： An electronic musical instrument including tone generators for generating tone signals each having predetermined tone pitches constituting a musical scale and tone keyers for respectively keying the tone signals, is further provided with a circuit arrangement for fluctuating the pitch of the tone at the start of the tone. The arrangement comprises a detector for detecting the start of the tone signal being played and a pulse generator producing a pulse signal upon receipt of the detected signal and controlling the tone generators to fluctuate the pitches thereof at the start of the tone signals.

摘要： A sound generating system comprising means for producing signals of fundamental frequency, and means for generating formant frequency signals of frequency higher than the fundamental frequency which starts oscillation synchronizingly with said signal of fundamental frequency and continues said oscillation only for a desired length of time during the period of said signals of fundamental frequency, wherein said signals of formant frequency are generated at the same starting point for each frequency interval as said signals of fundamental frequency. Sounds thus produced consist of a fundamental frequency component and harmonic components, and the frequency spectrum of said sounds presents a peak in a formant frequency, so that the system eliminates the necessity of using an electrical filter having complicated frequency characteristics in electrically producing sounds having a complicated frequency spectrum.

摘要： An electronic musical instrument produces musical tones simulating a natural flute voice closely. The instrument comprises a fundamental tone-pitched signal generator, a keyer associated with a key and keying the signal from the generator with an amplitude responsive to a depressing force of the key, a filter giving a tone color, as a formant component, of the flute voice to the keyed signal from the keyer, a tone pitched noise generator with a percussive envelope having a peak amplitude which is less responsive to the key-depressing force than the amplitude of the fundamental tone pitched signal, or not responsive to the key-depressing force. The tone signal having the flute formant and the noise signal having the pitch sense are mixed and radiated from a loudspeaker.

摘要： A marimba tone forming system mixes a fundamental tone signal of a flute voice, having an envelope whose rising time is about 10 milliseconds and whose attenuation time is about 1 second, with a sixth or third order overtone signal of the same voice, having an envelope whose maximum amplitude is slightly larger than that of said fundamental tone signal, whose rising time is about 3 to 5 milliseconds and whose attenuation time is about 100 milliseconds. The said fundamental tone and said overtone sound at the same time.

摘要： A circuit for achieving the moving or changing formant effect in an electronic musical instrument such as an electric organ. The circuit employs a band-pass amplifier with parallel T resistivecapacitive feedback circuits in which an FET (Field Effect Transistor) is employed as a variable resistance to cut in, by degrees, one of the T feedback circuits. The effective resistance of the FET and thus the band-pass of the amplifier are varied by a capacitive and resistive timing circuit that is controlled via a keying circuit from one or more keys or other player-operated controls, such as the manual keys of an electric organ.
