摘要： Electronic polyphonic music apparatus employing digital music synthesis circuitry. A preferred embodiment of the apparatus includes three digitally-controlled tone generators (200, 300, 400) which simultaneously produce three signals of independently selected frequencies. The generators (200, 300, 400) operate in response to a tone generator controller (150) which produces digital signals for controlling the rest or off period of each of the generators and frequency control circuitry for producing digital signals for controlling the tone or frequency of each of the generators. The output of each of three tone generators is coupled to a single digitally-controlled variable attenuator bank (205) by way of multiplexer circuitry (201, 202, 203). The tone generators are controlled so that only one generator is coupled to a given attenuator at any given time. The output of the attenuator bank is connected to an audio transducer (700) through a conventional audio amplifier (600). Also disclosed is a structure bonding the circuitry in LSI format to the transducer.

摘要： An electronic organ or the like is provided with a plurality of frequency generators (82, 84, 86, Fig. 5) greatly less than the number of keys on the organ. Each generator is capable of producing an electrical oscillation of proper frequency for any musical note on the organ keyboard. The frequency generators are assigned to the desired frequency called for by depression of any key. Pulses are dropped (40, 50, 58, Fig. 3; 68, Fig. 4; 106, 106a, 106b, Fig. 5) preferably in different numbers (134, 136, 140, Fig. 6) from the frequency generators (124, 126, 128, 130, 132, Fig. 6) to avoid locking of oscillators to one another, either in octave or any harmonic relation.

摘要： An electronic musical instrument (1) simulates a stringed musical instrument such as a guitar. Musical sounds of appropriate frequency and envelope are provided. An oscillator (34) provides a reference clock frequency to a digital counter (38) which is controlled by touch circuits (46) and a digital circuit (36) to divide the reference clock frequency into an appropriate output frequency. An envelope control circuit (40) shapes the output frequency to simulate a stringed musical instrument.
