Abstract
The present invention is directed to a musical sound modification apparatus and method whereby natural musical instrument sounds are analyzed to extract time variant information of pitch, amplitude and timbre, as Musical Sound Modification Data, which are stored in a temporary memory area as pitch Template, amplitude Template and timbre Template for each of attack part, sustain part and release part of a musical sound. Musical Sound Modification Data for one musical note is formed by selectively joining each Template of attack part, sustain part and release part, and for each of pitch, amplitude and timbre, and is pasted to a series of musical note data in music data. At music reproduction by the music data, the generated musical sound gives a “realistic feeling” to human ear owing to supplied time variant characteristics, because each of pitch, amplitude and timbre of the musical sounds corresponding to the musical note data is modified by said Musical Sound Modification Data.
