DISPOSITIF DE GÉNÉRATION DE NOTES DE MUSIQUE, INSTRUMENT DE MUSIQUE ÉLECTRONIQUE, PROCÉDÉ ET SUPPORT D'INFORMATIONS

摘要

A musical note generation device includes at least one processor, performing a process of generating convolved sound waveform data by convolving first sound waveform data corresponding to pitch information associated with a specified key with second sound waveform data corresponding to an impulse response; a process of generating third sound waveform data by respectively reducing, among frequency components included in the generated convolved sound waveform data, amplitudes of respective frequency components of a fundamental tone and harmonics of the fundamental tone corresponding to a pitch indicated by the pitch information; and a process of outputting piano sound waveform data generated on the basis of the generated third sound waveform data generated.
