Abstract: The electric organ of the invention includes tone generators and frequency dividers for providing musical tones extending through a number of octaves. Tones in different octaves are combined to provide desired tone characteristics. A pedal board controls a pedal generator which provides bass tones, and selectively couples tones from the dividers to provide major and minor chords associated with the pedal tones played. A rhythm system is provided for chopping or modulating the chords in different rhythm patterns, and to provide percussion sounds and bass sounds in the various rhythm patterns. Logic and switching circuits control the rhythm patterns.

    1. A rhythm system for use with an electric organ including in combination:
  • clock means for producing a train of clock pulses occurring at a given repetition rate;
  • divider means connected to said clock means for producing timing voltages at time intervals controlled by said clock pulses, said divider means being adapted to be reset by a potential applied thereto;
  • logic means connected to said divider and having a plurality of outputs, said logic means producing at each output pulses in a different rhythm pattern under control of said clock pulses;
  • operating means for the rhythm system;
  • switch means connecting said outputs to said operating means for selectively applying said pulses for said rhythm patterns thereto; and
  • clamp means connected to said switch means and responsive to operation thereof, said clamp means including means for applying a clamp potential
