    摘要: Prior art synthesizers often select a small interval d to detune. For example, if the nominal oscillator frequency was 1000 Hz, then applying a detune parameter of 10 cent would result in a detuned oscillator frequency of 1006 Hz. However, at the next octave, the nominal frequency would be 2000 Hz with the detuned oscillator frequency of 2012 Hz. Accordingly, a detuned oscillator has a frequency deviation which is proportional to its nominal frequency. Hence, when mixing detuned oscillators, the resulting signal has a beat frequency which varies with the pitch and doubles with each octave. An aim of the present invention is to provide a music synthesizer whereby sounds are generated with a constant optimum beat across a large range of tones. The present invention relates to a music synthesizer comprising a first and second oscillator and a signal generator which applies a constant beat parameter to a pitch signal to derive the input for said second oscillator, thereby enabling a synthesizer output to be generated at a substantially constant beat.

    摘要: 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.
