ABSTRACT:
A programmable rhythm apparatus for use with an electronic musical instrument comprising a sequential pulse generator, a plurality of individually programmable rhythm channels or tracks each producing an output pulse pattern in response to the sequential pulse generator and a standard voice generation circuit to receive the pulse output pattern from the programmed rhythm channels. The voice generation circuit produces a signal representative of an unpitched musical instrument with a rhythm pattern corresponding to the pulse output pattern of an individual rhythm channel. The voice generation circuit output signals corresponding to each rhythm channel and representing different unpitched instruments are combined and applied to an audio transducer. Each individual rhythm channel can be programmed by the instrument player to provide a pulse output sequence representative of any rhythm pattern desired. Each rhythm channel has a plurality of logic means and a selection means. The instrument player uses the selection means to set or program various ones of the plurality of logic means to form a pattern corresponding to the desired rhythm. Thereafter, each set logic means produces an output pulse upon receipt of a sequence pulse from the pulse generator. A switching network can be provided between the outputs of the rhythm channels and the input terminals of the voice generation circuit to provide increased flexibility and versatility. Furthermore, the programmable rhythm apparatus can be used in conjunction with the fixed rhythm matrices of the prior art to provide selectable rhythm variation for certain unpitched musical instruments and the standard rhythm for others.
