ABSTRACT OF THE DISCLOSURE The invention relates to a device for the acoustic plurality of a musical time. Said musical time comprises a plurality of musical beats with musical properties, such as vo- lume, pitch, tempo and reproduction period. These musical pro- perties can be varied for each beat separately. To this end the device comprises N switch elements each connected to an associated binary counter with two outputs, one output of which is connected to a first input of a first gate circuit and the other output of which is connected to a first input of a second gate circuit, a second input of each of the first and second gate circuits being connected to one of N outputs of a scanning element for the cyclic consecutive scanning of the N first and second gate circuits, wherein the N first gate circuits are con- nected by their outputs to a first input of a first switch circuit and the N second gate circuits are connected by their outputs to a first input of a second switch circuit, wherein a second input of the first and second switch circuits is connect- ed to the output of a tone generator unit, the outputs of said first and second switch circuits being connected to a sound re- production system. Thereby, the device is capable of repeating a very complex, repetitive sequence of beats.
