ABSTRACT:
In a musical tone signal generating apparatus, first sampling data and second sampling data are multiplied together by a convolution operation, wherein first sampling data indicates instantaneous amplitude values of a musical tone waveform generated from a keyboard, for example. The second sampling data is obtained from an impulse response waveform signal indicative of a reverberation characteristic of room or an acoustic characteristic of amplifier or musical instrument such as a guitar or a piano. Or, the second sampling data can be obtained from a waveform signal indicative of animal sound, natural sound or the like. Then, the multiplication result of first and second sampling data is combined together into the musical tone waveform data, whereby a musical tone signal corresponding to this musical tone waveform data is generated. Thus, the musical tone is modulated with another sound such that the reverberation or acoustic characteristic will be simulated in the musical tone to be generated, whereby the variable musical effect can be applied to the musical tone.
