1. An electronic apparatus comprising:
- a magnetic tape in which is sequentially recorded a plurality of music number data records comprised of tone data in digital form, a blank space being interposed between adjacent music number data records;
random number generator means for generating a random number;
detector means for detecting the sequence of music number data records recorded on said magnetic tape by detecting the blank spaces;
selecting means responsive to said detector means and to said random number generator means for selecting, from said magnetic tape by fast feeding said magnetic tape in one of forward and reverse directions until said detector means detects the music number data record corresponding to said random number, from said magnetic tape the music number data record having a number in the sequence of music number data records which is the same as the random number generated by said random number generator means;
reproducing means for reproducing the music number data record selected by said selecting means;
memory means for storing digital tone data of music number data record reproduced by said reproducing means;
control means for controlling the reading and writing of the digital tone data to and from said memory means;
a tone generator for generating a tone signal as a function of the digital tone data which is read out from said memory means; and
a sound system coupled to said tone generator for amplifying the tone signal to an audible sound.

Abstract
A plurality of music number data records of several hundreds of music numbers are sequentially recorded on a magnetic tape, such as a compact cassette tape with a blank space therebetween. The recorded music number data records are continuously and randomly reproduced and stored in digital form in a RAM so as to continuously auto-play a plurality of music numbers by means of a tone generator.
