Abstract
An apparatus and method for electronically producing music includes an adder coupled to a sinusoid memory, wherein the sinusoid memory is a look-up table including various sinusoidal waves having differing output characteristics. A feedback path between the output of the sinusoid memory and an input of the adder includes a register coupled to a feedback modifier device. The feedback modifier device includes a second look-up table which substitutes a feedback component .beta. into the sinusoidal wave output from the sinusoid memory. The output of the feedback modifier device is an arbitrary function of the selected wave from said sinusoid memory and the selected value of the feedback component.
