Abstract

A performance apparatus capable of reproducing performance data having a desired tempo, even if performance data having the desired tempo is not present in a play list. In a search, a main point value indicated in each of meta data in music information files respectively corresponding to pieces of music registered in the play list is compared with a target tempo value. If the main point value falls within a range in which main point does not vary more than plus or minus 3% from the target tempo value, the music whose main point value is currently compared with the target tempo value is determined as intended music. If the intended music is not present in the play list, music data having the target tempo is automatically produced and reproduced.

Claims

1. A performance apparatus comprising:

a storage unit adapted to store a plurality of performance data;

a setting unit adapted to set a target tempo;

a search unit adapted to, from among the plurality of performance data stored in said storage unit, search for intended performance data having a tempo falling within a predetermined range including the target tempo set by said setting unit;

a selection unit adapted to, if the intended performance data has been found by said search unit, select the intended performance data, and adapted to, if the intended performance data has not been found, produce all new performance data having a tempo corresponding to the set target tempo and select the produced performance data; and

a reproduction unit adapted to reproduce the performance data selected by said selection unit.

2. The performance apparatus according to claim 1, including:

a measurement unit adapted to measure a heart rate of a user,

wherein said setting unit is adapted to set the target tempo based on the heart rate measured by said measurement unit.

3. The performance apparatus according to claim 1, wherein the performance data stored in said storage unit are audio data, and the performance data produced by said selection unit is MIDI data.

4. A performance apparatus comprising:

a transmitter-receiver unit adapted to transmit and receive data to and from an external device connected thereto;

a notification unit adapted to notify the external device of a tempo range via said transmitter-receiver unit;

a storage unit adapted to receive performance data from the external device via the transmitter-receiver unit and store the received performance data;

a reproduction unit adapted to reproduce performance data; and

a changing unit adapted to change the tempo range in accordance with an instruction given by user'"'"'s operation.

5. The performance apparatus according to claim 4, including:

a selection unit adapted to select, from among a plurality of the performance data stored in said storage unit, performance data having a tempo falling within the tempo range,

wherein said reproduction unit is adapted to reproduce the performance data selected by said selection unit.

6. A performance apparatus comprising:

a transmitter-receiver unit adapted to transmit and receive data to and from an external device connected thereto;

a notification unit adapted to notify the external device of a tempo range via said transmitter-receiver unit;

a storage unit adapted to receive performance data from the external device via the transmitter-receiver unit and store the received performance data;

a setting unit adapted to set a target tempo;

a search unit adapted to search for, from among a plurality of performance data stored in said storage unit, intended performance data having a tempo falling within a predetermined range including the target tempo set by said setting unit;

a selection unit adapted to, if the intended performance data has been found by said search unit, select the intended performance data, and adapted to, if the intended performance data has not been found, produce performance data having a tempo corresponding to the set target tempo and select the produced performance data;

a reproduction unit adapted to reproduce the performance data selected by said selection unit; and

a tempo range changing unit adapted to change the tempo range.

7. The performance apparatus according to claim 6, wherein said selection unit is adapted to produce all new performance data having a tempo corresponding to the set target tempo and select the produced performance data, if the intended performance data has not been found by said search unit.

8. The performance apparatus according to claim 6, including:

a target tempo changing unit adapted to change the set target tempo in accordance with an instruction given by user'"'"'s operation,

wherein said tempo range changing unit is adapted to change the tempo range when the target tempo changed by said target tempo changing unit falls outside the tempo range.

9. The performance apparatus according to claim 6, including:

a measurement unit adapted to measure a heart rate of a user,

wherein said setting unit is adapted to set the target tempo based on the heart rate measured by said measurement unit.

10. The performance apparatus according to claim 6, wherein the performance data stored in said storage unit are audio data, and the performance data produced by said selection unit is MIDI data.

11. A computer-readable storage medium storing a program for causing a computer to execute a method for controlling a performance apparatus including a storage unit, the method comprising:

a setting step of setting a target tempo;
