Abstract
A musical sound signal synthesizer with a simple construction for synthesizing complex musical sound waveform signals including many harmonics in a peculiar form. A phase information generator 11 supplies phase information x with a sawtooth wave changing according to a phase of the musical sound to be generated via a calculator 12 to a sine wave table 13 , from which output waveform information y is read out. The waveform information y is fed back to the calculator 12 via an absolute value transformer 14 , a low pass filter 15 and a gain controller 16 . The output waveform information y outputted from the sine table 13 is transformed nonlinearly, which is fed back to the phase information x, which makes a complex change. As a result thereof, the waveform, which is represented by waveform information outputted from the sine wave table 13 , becomes peculiar for a musical sound signal synthesized by phase or frequency modulation technique.
