Claims

[Claims for Utility Model Registration] 1. An automatic performance data storage means for storing automatic performance data, a sound source means for producing musical sounds, and a start point and end point of any repeated portion of the automatic performance when the user performs the automatic performance. a performance point designation means for specifying, respectively, the start point and the end point of a repeating part of an arbitrary automatic performance when the user performs the non-automatic performance; the address of the automatic performance data storage means corresponding to the point,
repeat address storage means for storing repeat addresses as repeat addresses; point designation switching means for arbitrarily switching between the performance point designation means and the non-performance point designation means; automatic performance based on the start point of the automatic performance designated by the user; At the time when the performance data is read from the automatic performance data storage means, the sound source means starts automatic performance, and when the automatic performance data is similarly read based on the end point of the automatic performance specified by the user. An automatic performance device comprising: automatic performance control means for causing the sound source means to end automatic performance. 2. When the user specifies the start point as a point later than the end point, the point designation switching means changes the respective addresses corresponding to the start point and end point stored in the repeat address storage means. The automatic performance device according to claim 1, further comprising address exchanging means for exchanging addresses.
