Abstract:
A tone synthesizing device comprising:a loop section including at least a signal delay element, a delay amount of said signal delay element being controlled in accordance with tone pitch designating information; anda driving signal generation unit that generates a driving signal by modifying a loop output signal from said loop section in accordance with a performance parameter and supplying the generated driving signal to said loop section, said driving signal generation unit including:a nonlinear conversion section that performs a nonlinear conversion on an input signal corresponding to the loop output signal and the performance parameter, said nonlinear conversion section switching an input-output characteristic, to be used for converting the input signal, into one of at least first and second input-output characteristics in accordance with intensity of a signal based on the loop output signal or the input signal; anda control section that restrains a period in which the input-output characteristic to be used for converting the input signal shifts from said first input-output characteristic to said second input-output characteristic from becoming shorter than a pitch period corresponding to a tone pitch designated by the pitch designating information.
