Rhythm sound generator

For use in an electronic organ including a rhythm pattern generator which produces sequences of trigger pulses, each sequence characteristic of a particular rhythm, and a loudspeaker for acoustically reproducing electrical signals generated within the organ, an electronic circuit for producing an electrical signal which when reproduced by the loudspeaker simulates the sound produced when a group of persons clap hands substantially in unison, said circuit comprising:

• timing circuit means connected to receive a selected sequence of trigger pulses from said rhythm pattern generator for producing a group of trigger signals in timed relationship to each trigger pulse in the said selected sequence and to each other,
• at least first and second sound signal sources for respectively producing in response to an applied trigger signal first and second signal bursts of differing tonal characteristics, said first sound signal source comprising a source of random noise,
• means for applying at least one trigger signal of the said group to each of the sound signal sources for causing said sound signal sources to produce a group of signal bursts of differing tonal characteristics in timed relationship to each trigger pulse in the said selected sequence and to each other,
• means for combining the signal bursts produced by the said at least first and second sound signal sources and producing said electrical signal and
• means for applying said electrical signal to the loudspeaker.
