ABSTRACT:
The present invention is directed to a digital touch responsive tempo generating device for use in an electronic musical instrument, preferably an electronic organ. The instrument player selects a desired tempo to control a standard rhythm unit or other circuit either before or during playing by repetitively actuating a touch plate at a rate corresponding to the desired tempo. A digital value related to the time interval between predetermined repetitive touches by the instrument player is stored in a digital circuit having a memory under control of a clock circuit. A tempo generator circuit coupled to the digital circuit produces tempo output pulses spaced apart as a function of the time interval between the repetitive touches.
