  • Patent number: 4366741
    Abstract: An electronic piano has a keyboard and an electronic piano circuit connected to a micro-processor used to control a CRT device to provide a video note display concurrently with the depression of one or more keys. A keyboard representation located adjacent the screen of the CRT device is associated with lights used to indicate the key or keys that are played. Manually operated controls cooperate with the micro-processor to allow the back clearing of the screen one note at a time, remove all the notes, retain all the notes, indicate sharp or flat mode of each note, and indicate the duration that a key is depressed by elongating the note on the screen. A metronome unit is used with the micro-processor to provide a visual beat marker on the screen that sequentially moves across the screen. A movable frame connects the CRT device to the piano.
