ABSTRACT:
An automatic rhythm performance system is provided with a rhythm pattern changing circuit comprising a white noise source and a sample hold circuit which samples the output of the white noise source in response to a pulse signal occurring at the beginning of every measure of a rhythm to produce a sustained voltage of a sampled value which will be different for every measure. The sample hold circuit voltage is applied to a rhythm selecting circuit to modify the preselected pattern of the rhythm.
