An apparatus for encoding data representative of keyboard music is disclosed. In the preferred embodiment, the data source is a keyboard which is played by a musician which incorporates a set of switches forming key closures. The closures themselves represent the music. The music is encoded by grouping the keyboard in convenient sized groups, typically octaves, and all of these groups are input to a buffer. A multiplexer scans the buffer. Timed generators form the synchronization wave-forms, space wave-forms and mark wave-forms. All of these wave-forms are generated in timed sequence. They are input to a flip flop which forms an output word on a two wire carrier system. The two wire output encodes all data required for word decode; namely, clock, sync, mark, and space data.
