ABSTRACT:
An electronic circuit for simulating the sound of a skin head percussive instrument struck with a stick includes a pair of ringing oscillators of different frequencies both triggered by pulses from the rhythm pattern generator of an electronic organ, a circuit for combining the output signals from the two ringing oscillators in preselected amplitude proportions, and a circuit for distorting the combined signal in such a way as to non-linearly amplify the combined signal so as to produce an electrical signal having characteristics such that when acoustically reproduced produces a sound highly simulative of that produced when the membrane of a skin head instrument is struck with a stick.
