Abstract
Tempo information representing a performance tempo set at start of an automatic performance is stored in a first register. A tempo restoration switch is provided for reading out the tempo information from the first register and setting the tempo of the automatic performance by this tempo information. Even when the performance tempo is changed freely during the automatic performance, the tempo at the start of the automatic performance can be restored automatically by operating the tempo restoration switch. Tempo information representing a performance tempo set before start of tempo changing may be stored in a second register. A second tempo restoration switch may be provided for reading out the tempo information from this second register and setting the tempo of the autoamtic performance by this tempo information. Even when the performance tempo is changed freely during the automatic performance, the tempo before start of the tempo changing can be restored automatically by operating the second tempo restoration switch. Control of tempo primo and a tempo is thereby facilitated.
