PURPOSE:To synchronize completely the display of a music note data with the playing of music by storing auxiliary data such as a picture or a character to a storage means with key input in advance, reading the said auxiliary data in synchronizing with the recording or reproduing tempo of a main data such as a music signal and recording it on a magnetic tape. CONSTITUTION:When the tape recorder is set to the recording mode and a changeover switch 12 is thrown to the position of a terminal (a), a sound length detecting circuit 13 outputs a clock in synchronizisng with the music signal. The clock is counted by a counter 14, whether or not the count value is coincident with the sound length code of the music note of the 1st address recorded to a sound length RAM10 is discriminated by a coincidence circuit 15, and when they are coincident, a coincidence pulse is outputted from the coincidence circuit 15. An address generation circuit 9 revises sequentially the address of RAMs 10, 11 for sound length and interval, and a coding processing circuit 16 reads the sound length and interval code when coincident from both the RAMs 10, 11 and also gives them to a recording circuit 17 as the music note data, which is recorded on a magnetic tape T. |
