1. A performance apparatus comprising:
- a storage unit adapted to store a plurality of performance data;
a selection unit adapted to select any of the plurality of performance data stored in said storage unit;
a first reproduction unit adapted to reproduce performance data selected by said selection unit, as non-MIDI audio-data;
a control unit adapted to control said first reproduction unit such that preceding performance data being reproduced by said first reproduction unit is changed over to subsequent performance data selected by said selection unit and performance data reproduction is continuously carried out;
a musical tone characteristic acquisition unit adapted to acquire a musical tone characteristic of at least one of the preceding performance data and the subsequent performance data;
a generation unit adapted, based on the musical tone characteristic acquired by said musical tone characteristic acquisition unit, to generate stopgap performance data for connecting between the preceding performance data and the subsequent performance data; and
a second reproduction unit adapted to reproduce the stopgap performance data generated by said generation unit, as MIDI data,wherein said control unit is adapted to control said second reproduction unit such that the stopgap performance data of MIDI data is inserted between the preceding performance data of non-MIDI audio-data and the subsequent performance data of non-MIDI audio-data and is reproduced.

Abstract
A performance apparatus capable of reproducing music pieces while making changeover between the music pieces without disturbing the rhythm of exercise, dance, or the like performed by a user to the rhythm of music. A beat position is acquired that will appear in a preceding performance data for the first time after a preparatory time required for changing the reproduction of the preceding music piece to the reproduction of a subsequent music piece elapses from when a music selection instruction is given. The reproduction of the subsequent music piece is started at the same time when the music is reproduced up to the acquired beat position.

5. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method for controlling a performance apparatus including a storage unit storing a plurality of performance data, the method comprising:
-
a selection step of selecting any of the plurality of performance data stored in the storage unit; a first reproduction step of reproducing performance data selected in said selection step, as non-MIDI audio-data; a control step of controlling said first reproduction step such that preceding performance data being reproduced in said first reproduction step is changed over to subsequent performance data selected in said selection step and performance data reproduction is continuously carried out; a musical tone characteristic acquisition step of acquiring a musical tone characteristic of at least one of the preceding performance data and the subsequent performance data; a generation step of generating, based on the musical tone characteristic acquired in said musical tone characteristic acquisition step, stopgap performance data for use in connecting between the preceding performance data and the subsequent performance data; and a second reproduction step of reproducing the stopgap performance data generated in said generation step, as MIDI data, wherein said control step controls said second reproduction step such that the stopgap performance data of MIDI data is inserted between the preceding performance data of non-MIDI audio-data and the subsequent performance data of non-MIDI audio-data and is reproduced.
