Abstract
A keyer circuit for electronic organs and the like in which a single main keyer chip is formed by utilizing large scale integrated MOS technology with the chip adapted for use with organs having different information supplied to the multiplexing system. The chip provides output information to drive discrete circuitry and also has the necessary input for normal multiplexing operation of an electronic organ. The chip according to the present invention provides internal multiplexing for simple organs and standard external multiplexing for more complex organs.
