  • Patent number: 6079985
    Abstract: An electronic sound and music making device includes a memory that stores a plurality of sound segments, such as musical notes, animal noises, etc., a keypad having a series of keys, each of each indicates and is associated with a different one of the stored sound segments, and a set of visual indications, such as light emitting diodes (LEDs), that indicate when different ones of the sound segments are being played. The device repeats a programmable sequence of, for example, four of the stored sound segments to form a song while, simultaneously turning on different ones of the LEDs to indicate the different sound segments being played. The keypad enables a user to specify the identity and the order of the sound segments to be played and allows a user to substitute any of the sound segments stored in the memory with the sound segments being played so as to produce a new or different song.
