ABSTRACT:
An electronic musical instrument having a rhythm performance function includes a first memory for pre-storing plural rhythm tone kinds, rhythm selecting switches each capable of designating one of said rhythm tone kinds and a rhythm tone generator having plural channels. The selected rhythm tone kind is assigned to each channel of the rhythm tone generator. A rhythm tone corresponding to the selected rhythm tone kind is generated by each channel so that continuous rhythm tones will be generated by plural channels based on time division system. In addition, before playing a rhythm performance, rhythm patterns can be arbitrarily programmed and then stored into a second memory by operating the rhythm selecting switches and other switches corresponding to the predetermined rhythm tones of plural musical instruments. Further, the roll of rhythm tones can be continuously generated, wherein volume information stored in the first memory is determined such that tone volume of the roll of rhythm tones is set smaller than that of the normal rhythm tones.
