Abstract
There are provided an analyzer which processes a supplied original sound waveform signal so as to generate one or more analyzed waveform signal components, a synthesizer which receives and processes at least one of the analyzed waveform signal components from the analyzer so as to synthesize a waveform signal on the basis of the processing, and a control section which controls the respective parameters used in the analyzer and synthesizer independently of each other. At least output signal of the synthesizer is taken out and output as a tone signal. In order to achieve diversified control of the tone color or characteristic of a tone to be generated, a tone signal may be obtained by taking out the respective output signals of the analyzer and synthesizer for synthesis.
