ABSTRACT:
A four-operator sound synthesis integrated circuit comprises a first through a fourth sound synthesis operator, a first programmable multiplier connecting the output of the first operator to the input of the second operator, a second programmable multiplier connecting the output of the second operator to the input of the third operator, a third programmable multiplier connecting the output of the third operator to the input of the fourth operator, a fourth programmable multiplier connecting the output of the first operator a first input of a four-input adder, a fifth programmable multiplier connecting the output of the second operator a second input of the four-input adder, a sixth programmable multiplier connecting the output of the third operator a third input of the four-input adder, and a seventh programmable multiplier connecting the output of the fourth operator a fourth input of the four-input adder. The product of the combination is taken from the output of the four-input adder. Each programmable multiplier can be programmed to multiply from zero to one, e.g., zero, one-half, and one.
