发明名称 Musical tone generating apparatus
摘要 A musical tone generating apparatus is capable of reproducing natural musical tones while waveform memories of a nominal capacity. The apparatus comprises a first waveform memory 1a for storing first waveform data of one period of a stationary first waveform existing after an elapse of a certain period from the beginning of generation of a musical tone and a second waveform memory 1b for storing second waveform data of one period of a second waveform representing differential spectral components derived from spectral differences between a fundamental wave component and harmonic components of the non-stationary waveform determined immediately after the beginning of generation of the musical tone and a fundamental wave component and harmonic components of the first waveform. A first multiplier generates first multiplication data by multiplying the first waveform data with a first level coefficient which varies as a function of time and a second multiplier generates second multiplication data by multiplying the second waveform data with a second level coefficient which varies as a function of time. A level coefficient generator provides the first level coefficient and the second level coefficient while an adder sums the first multiplication data and the second multiplication data.
