Note selector circuit for electronic musical instrument

摘要: An electric organ utilizes digital encoding and time division multiplexing to transfer both function selection note information from manually operable switches respective memories, simultaneously produce tone signals corresponding stored information. A single circuit encodes in binary form the during successive scanning periods established by a circuit. plurality of codes are transferred on basis selector which selectively produces all selected signals, one output multiplexed form. The demultiplexed generate signal outputs. octave is responsive part each code reduces frequency signals. In response storage for memory function, operates maintain after deactuation thereto until it updated with new set notes.
