PURPOSE:To reproduce music according to the readout of bit patterns of a scale data and the music note length data from an RAM, by storing a plurality of music information with the bit pattern, transferring the one music information to the semiconductor memory RAM possible for rewriting and storing it temporarily. CONSTITUTION:A music reproducing circuit section 1 consists of a tone generator 2, an envelope generating section 3, an address counter 4, an amplifier 5 and a speaker 6. RAM sections 7, 8 have a storage capacity storing one music information. A large capacity recording medium stores a plurality of music information in the bit pattern. A control section 10 instructs the control of music recording, start/stop of music, transposition/modulation and tempo with the switch operation of an external input circuit. An oscillation and frequency division circuit 12 is connected to a music reproducing circuit 1 and the output is used as a basic clock of the circuit 1. |
