Electronic metronome and rhythm generator

Abstract

An electronic metronome for training musical students in various rhythm patterns is disclosed. The electronic metronome is battery powered and completely contained within a hand held component case for ease in transport and storage. A solid state memory device which may be selectively programmed with a plurality of digital logic signals by means of manual switches is automatically and repetitively accessed in a selected sequential order and at a selected rate and the digital logic signals stored therein are converted to audible 'clicks' or tones and inaudible pauses. Variable amplification circuitry coupled to the output of the memory device permits the volume of the clicks or tones to be selected by the operator and a pair of light emitting diodes permits the output of the memory device to be simultaneously converted to a visual signal. In a preferred embodiment of the present invention, selectable timing circuitry included within the access circuitry permits the output of the memory device to be accessed at a number of variable clock rates to further enhance the flexibility of the electronic metronome.
