Abstract: A tune data reproduction system is designed to operate differently in a reproduction mode and a quick reverse mode by using tune data and quick reverse sound data. Herein, the tune data represent progression of notes of musical performance, while the quick reverse sound data represent repetition of a prescribed sound indicating a quick reverse operation or reverse reproduction sounds being made from the tune data. In the reproduction mode, the system performs reproduction on the tune data to produce musical tones of the notes at a desired tempo in accordance with the progression of the musical performance. In the quick reverse mode, the system produces the quick reverse sound or the reverse reproduction sounds representing the musical tones of the notes which are reversely reproduced in a reverse direction reverse to the progression of the musical performance at a high speed.
