Rythm rate and tempo monitor for electronic musical instruments having automatic rhythm accompaniment

摘要

A microprocessor-based processing system for monitoring the tempo rate and rhythm in an electronic musical instrument having an automatic rhythm accompaniment unit. In a first mode of operation, the monitor displays the tempo of the rhythm accompaniment unit in numeric characters representing the number of beats per minute. In a second mode of operation, the monitor displays a numerical 1 representing the down beat in a first display device, a numerical 2 representing the second beat in adjoining display device, and successively incremented numerical integers associated with successive beats in successive numerical display devices until all numerical integers associated with beats have been displayed, thereby producing a timing display having a motion effect for synchronizing the music being played with the rhythm accompaniment tempo.
