Abstract

PURPOSE: To work the timbre of musical sound by providing a distortion generator with a distortion generation means having specific I/O characteristics between an input musical sound signal and an output musical sound signal and a changing means for changing a power out of the specific I/O characteristics. CONSTITUTION: An analog musical sound signal 2 is converted into a digital musical sound signal by an A/D converter 4 and the digital signal is supplied to a distortion generation circuit 6. When the input digital musical sound signal is defined as (x) and an output digital musical sound signal is defined as (y), the circuit 6 has an I/O characteristic expressed by y=1-(1-x)n between the values x, y when 0<x<=1 and has an I/O characteristic expressed by y=- 1-(1+x)<n> } when -1<=x<0. Since the depth of distortion is increased and double sounds are increased in accordance with the increment of the value (n), the I/O characteristics of the distortion generation means can be variously changed only by changing the value (n), the double sound constitution of the output musical sound signal (y) outputted from the distortion generation means can be optionally changed and the tone colors of musical sounds can be variously changed.
