Sound generator for producing ANGKLONG like sound

摘要

An electronic sound generator is developed for generating a sound similar to that of ANGKLONG (Indonesian terms), which comprises a circuit for generating a series of consequtive rectangular waves. A plurality of envelope wave generation circuits each produce an envelope wave having the same repeating cycle as that of each said rectangular wave and, one or more sound source circuits are used for generating signals substantially equal to the output waves of angklong, circuits in each of which an output of a sound source circuit is modulated by the relevant envelop wave. A loudspeaker sounds the modulated signal as a musical sound. In a record embodiment the sound generator further comprises a first gate to which the modulated signal is directly applied, a second gate is connected in series with the volume and/or tone control circuit, means for opening said first and second gates alternatively and a means for combining the outputs of said first and second gates to provide a musical sound from the loudspeaker.
