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.
