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.

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： In the case where an automatic reading file composed of plural kinds of detailed parameters stored in a transportable storage device whose attachment is detected has been already read in an apparatus, it is determined whether update, to a currently-read automatic reading file, of an automatic reading file stored in a storage section is carried out or not in accordance with a user's instruction, and is controlled so as to carry out a process. Namely, in the case where an automatic reading file has not been read yet, the automatic reading file stored in the storage section is updated to the currently-read automatic reading file without any condition. On the other hand, if an automatic reading file has been already read, the automatic reading file stored in the storage section may be edited on the basis of it.

摘要： User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. Digital audio signals processed by a first signal processing circuit are stored into a memory and transmitted to a second signal processing circuit via a cascade-connection. The second signal processing circuit adds the audio signal, processed for each of the steps, to audio signals input via the cascade-connection and writes added signal into the memory.
