MUSICAL TONE SYNTHESIZER AND COMPUTER RECORDING MEDIUM RECORDED WITH MUSICAL TONE SYNTHESIZING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a musical tone synthesizer capable of imparting fluctuations to musical tones.;SOLUTION: A driving signal is formed by changing a loop output signal taken out of a loop section including signal delay section 9, 11, 13 and 15 according to the difference from a bow speed Vb and is supplied to the loop section. A non-linear transformation section 4 subjects the input signal meeting the above difference to non-linear transformation to change the signal to input and output characteristics at the time of the small input signal and input and output characteristics at the time of the large input signal according to the signal based on the loop output signal and suppresses the period changing to the input and output characteristics at the time of the large input signal from becoming shorter than the pitch period of the loop output signal loop. A toughness effect signal generating section 7 forms the fluctuation signal having the period components meeting the magnitude of the loop output signal.;COPYRIGHT: (C)2004,JPO
