Abstract
This invention relates to a circuit for use in an electronic musical instrument such as an organ, the instrument having two separate sources of bass signals and transducing elements for converting the bass signals into a sound output. The circuit is operative to prevent signals from one of the sources from being applied to the transducing elements when signals from the other source are present. For a preferred embodiment, a predetermined signal, such as a keying signal, is generated when signals from the other source are present and this predetermined signal is utilized to shunt signals from the other source to ground or to otherwise inhibit the application of these signals to the transducing elements.
