Abstract
When a playback speed of a recording medium such as a compact disc (CD) or the like is changed, the change of this playback speed is reflected in a clock which controls a tempo of automatic play. In the background of music reproduced from the recording medium, playing data provided during the play is written in a memory (211) in a real time fashion. When the automatic play is carried out in accordance with the content stored in the memory (211), the present invention includes a mode (A) in which the changed state of the playback speed of the CD and the tempo/musical sound pitch states of automatic play are automatically reproduced in the same states as those in the recording timing point, and a mode (B) in which the playback speed of the CD is automatically returned to the original speed before being changed and the tempo/musical sound pitch states of automatic play are automatically changed in response thereto.
