ABSTRACT OF THE DISCLOSURE An integrated keyer system for use in electronic organs comprising a plurality of discrete integrated circuit chips each corresponding to two adjacent octaves of the keyboard and con- nected in series to accommodate the entire keyboard. The keyer system is adapted for use in multiplexed systems wherein the key- switch closure information is encoded in a time division multi- plexed data stream fed through a plurality of the keyer chips, which are connected in series. Each of the keyer chips includes a plurality of tone inputs and outputs and a divide-by-four circuit for lowering the tones in by two octaves. The keyer chips also include serial data inputs and outputs and a demultiplexer for demultiplexing the serial data stream at the serial data input to produce a plurality of control signals corresponding to keydown signals in the serial data stream, which are fed to the individual keyers. The demuliplexer, which may be in the form of a shift register having latches connected between the various stages thereof and the keyers, also serves to delay the serial data stream by two octaves.
