Abstract
Abstract Tone data produced by operating a keyboard is stored in a RAM to be saved into a tape recorder through an interface. Of a plurality of music numbers saved in the tape recorder a selected one is loaded into the RAM through the interface. A tone generator converts the tone data from the RAM into a tone signal which is sounded from a loudspeaker. The save and load operations are all controlled by a CPU.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
An electronic apparatus comprising: a keyboard for generating plural series of tone data; a title data input means for generating title data corresponding to each said series of tone data; a memory means coupled to said keyboard and to said title data input means for storing said tone data and said title data; a tone signal generating means for generating a tone signal corresponding to tone data stored in said memory means; an accoustic converter means coupled to said tone signal generating means for converting said tone signal into sound; means coupled to said memory means for recording and reproducing on a recording medium a plurality of sets of said tone data and said title data stored in said memory means such that each set includes a series of tone data and its corresponding title data; and control means coupled to said title data input means, said memory means, said tone signal generating means and said recording and reproducing means, for scanning said recording medium to identify a selected title data from said recorded sets and for transmitting the series of tone data from the set to which said selected title data belongs from the recording medium to the memory means.
