摘要： Basic tone waveform corresponding to a designated tone color and pitch is generated in each of a plurality of channels. Effect is imparted to the basic tone waveform in accordance with an algorithm for providing a predetermined effect, independently for each of the channels. The effect to be imparted is controlled in accordance with the designated tone pitch, separately for each of the channels. The effect impartment may be conducted using a processor, such as a DSP, executing a predetermined program containing a predetermined effect-imparting algorithm. In one example of the effect-imparting algorithm, a delay loop is employed through which an input exciting signal is circulated while being delayed, and an effect specific to an electromagnetic pickup of an electric guitar can be approximated by controlling the delay amount in the delay loop. In another example of the effect-imparting algorithm, a ransom signal is generated to control a cutoff frequency on the basis of the random signal, the basic tone waveform is filtered in accordance with the thus-controlled cutoff frequency, and the resultant filtered tone waveform is circulated through a delay loop whose delay amount is controlled in accordance with the designated tone pitch.

摘要： A reverberation effect imparting system includes plural comb filters, each of which has a signal delay line and a feedback loop for filtering a delayed output signal from the delay line and feeding the filtered signal back to the input side with a variable loop gain. The device further includes a junction section which receives the respective output signals from the delay lines of the plural comb filters. The junction section controls the received signals with respective variable scattering coefficients and sums up the thus-controlled signals, so as to introduce the summed signal into the feedback loop of each of the comb filters. In this manner, reverberation control according to the waveguide theory is performed by the junction section, while the conventional-type reverberation control is performed by the comb filters. Thus, reverberation can be controlled through a combination of the two controls.

摘要： A musical tone synthesizing apparatus is designed to simulate the acoustic sounds of non-electronic musical instruments. In the non-electronic musical instrument providing the resonator such as the piano and guitar, the produced acoustic sound contains three kinds of sounds, i.e., a direct sound, a resonant sound and a transient sound. Herein, the direct sound is produced directly by playing the instrument, the resonant sound is produced from the resonator based on the direct sound and the transient sound is produced when the impulse to be occurred by playing the instrument propagates through the resonator. Thus, signals simulating these sounds respectively are mixed together so as to produce the synthesized musical tone signal, which well-simulates the acoustic sound.

摘要： A musical tone synthesizing apparatus which is suitable for simulating and synthesizing the percussion instrument tone provides a closed-loop including at least an adder and a delay circuit. An input signal corresponding to a musical tone signal to be synthesized is supplied to the adder from an external device. The adder adds the input signal to its feedback signal. The output of adder is delayed by a delay time in the delay circuit, wherein delay time is controlled by a modulation signal. Then, delayed output of the delay circuit is fed back to the adder as the feedback signal. Thus, the output of adder or a signal propagating the delay circuit is picked up as a synthesized musical tone signal. Preferably, it is possible to provide a plurality of delay circuits.

摘要： In a musical tone synthesizing apparatus, employed by an electronic musical instrument, an excitation signal circulates through a waveguide to form a musical tone signal corresponding to a synthesized musical tone. The waveguide is configured by a loop circuit containing an adder, a delay circuit, a filter and an amplifier. A delay time used for the delay circuit is determined in response to a tone pitch of a musical tone to be produced, while a filter coefficient used for the filter is determined in response to a tone color of the musical tone to be produced. A multiplication coefficient used for the multiplier is generated in accordance with one of the tone pitch and delay time; or the multiplication coefficient is computed on the basis of the tone pitch and a decay rate which is set by a performer. In addition, a different multiplication coefficient can be generated in response to a state of an envelope waveform of the musical tone to be produced. For example, the multiplication coefficient to be generated for an attack portion of the envelope waveform can be differed from the multiplication coefficient to be generated for a decay portion of the envelope waveform. By finely controlling a loop gain of the waveguide corresponding to the multiplication coefficient, a fine control can be performed for the synthesis of the musical tones.
