ABSTRACT:
According to the invention, formant waveform signals which are waveforms synthesized from frequency components corresponding to formants of musical tones, are stored and read out or generated. When such formant waveform signal is read out or generated, the density of frequency components of the formant of the formant waveform signal is controlled and also the frequency of a formant center signal which is to be synthesized is a center signal with the formant waveform signal is controlled. In this way, the formant waveform signal is synthesized on the formant center signal. Thus, the density of formant frequency components and the formant center signal frequency can be controlled separately and independently. Further, the kind of formant waveform signal is switched according to musical factors of musical tone. Thus, different kinds of formant waveform signals to be output are switched according to musical factors of musical tones.
