Abstract: A device for electronically simulating vibrato and tremulant effects and the radiation effects produced by a rotary loudspeaker with the aid of two loudspeakers, in which a musical tone signal is applied to a variable delay device associated with one of the loudspeakers. The frequency modulated signal produced by the variable delay device is also subjected to amplitude modulation, controlled in synchronism with the variable delay device, and the resulting composite signal applied to the other loudspeaker. Additionally, the high frequency components of the frequency modulated signal from the variable delay device are summed, in and out of phase relationship, with the composite amplitude modulated signal to simulate the effect of a rotating high frequency horn radiator.

Abstract: A tremulant circuit includes cascaded phase shifting networks in right and left amplifying channels of an electronic organ. An oscillator and associated circuitry produce offset signals of different wave shape which energize lamps associated with light responsive impedances in the phase shifting networks in the right and left channels. A switching circuit interconnects the phase shifting networks in different configurations to adapt the tremulant effect to a selected organ voice in order to produce the most pleasing and realistic acoustical output.

Abstract: Modulation systems for electrical signals representing music in which synchronous vibrato and tremolo modulations are applied to a flute signal in one channel, the vibrator being produced by a bucket brigade modulator and the tremolo by a balanced modulator in cascade with the bucket brigade modulator, and in which in a second channel tones other than flute tones, and pedal tones, are separately treated to have independent vibratos, and in which balanced modulators for modifying the amplitude of the tone signals are concurrently controlled by a common expression voltage. In one modification flute signals are vibrato modulated in opposed phases, and passed via diverse filters to a common tremolo modulator. Provision is made for combining the inputs of the channels, the outputs of which are electroacoustically transduced by separated loudspeakers. Provision is made for slowly varying the frequency of a sub-sonic modulating oscillator, which is either turned off, or operates at about 1 or about 6 Hz., in proceeding from any one of these three values to any other, the rate of variation being such as to simulate the rate which occurs when the modulations are produced by rotation of a mechanical device such as a rotating loudspeaker.

Abstract: A sound effect circuit with a phase shifter producing a signal shifted in phase with respect to an input signal, a combining circuit for arithmetically combining the input and phase shifted signals to produce an output signal, an oscillator for periodically modulating a characteristic frequency of the phase shifter and a modulation control circuit. The modulation control circuit causes the modulation rate to gradually increase when modulation is manually switched on and to gradually decrease when modulation is switched off. The modulation control also causes the characteristic frequency to vary inversely with the modulation rate. The system defined by a part of the circuit producing a first output signal proportional to the sum of the input and phase shifted signals has a comb shaped frequency response curve and a part of the circuit producing a second output signal proportional to the difference between the input and phase shifted signals has a comb shaped frequency response curve inversely related to that of the summing part of the circuit. When the two output signals are fed to separate speakers, the total frequency response curve of the two systems taken together is substantially flat, but the distribution of energy in the frequency spectrum moves in space as the modulation proceeds to produce a new "stereo phase shift" sound effect. A rotary potentiometer for mixing the first and second outputs signals with each of the input signal and the phase shifted signal in selected proportion provides a third output signal with selectively variable characteristics.

Abstract: A method and means for modulating the frequency of an analog signal to achieve a vibrato effect wherein the analog signal is transmitted through an analog shift register or delay line under the control of a digital clock signal and wherein the frequency of the digital clock signal is varied at a rate equal to the desired rate of modulation of the analog signal. In this manner, the output of the shift register is a delayed version of the input thereto, with the frequency modulated at the same rate that the clock signal frequency is modulated. According to the preferred embodiment of the invention, first and second shift registers are utilized and the analog signal is divided into upper and lower frequency bands which are separately applied to the two shift registers. Furthermore the shift register which receives the lower frequency band is clocked at one-half the rate of the shift register which receives the higher frequency band.

Abstract: An electronic expression device for producing a tremulant effect. The device has a distributor having one input terminal and a plurality of output terminals, a plurality of transmission channels being connected to the respective output terminals of the distributor, and a coupler for coupling the output signals of the channels. At least one of the channels has a modulator having a characteristic such that at least either the modulation depth or the modulation frequency increases in accordance with an increase in the frequency of the input signal and the modulation depth exceeds .+-. .pi./2 radian for phase modulation and 100% for amplitude modulation in a high frequency range. The distributor can be such as to produce different phase shifting characteristics in the signals at the respective output terminals and the channels can have different phase shifting characteristics from each other for securing a further novel tremulant effect. The audio frequency signal applied to the input terminal of the distributor is translated in such a manner that vectors of the signal are fluctuating differently in frequency, phase and amplitude.
