Abstract

As the user executes a performance on a preliminary or trial basis, performance data based on the user'"'"'s performance are evaluated, a performance tendency of the user is extracted as a result of the extraction, and then, performance tendency information, indicative of the extracted performance tendency, is generated. Psychological state, such as a mood or feeling, of the user is detected from the performance tendency, and feeling information, indicative of the detected psychological state, is generated. Then, tone color control information corresponding to the generated feeling information is acquired from a storage section, such as a “mood/feeling” vs. tone color control” correspondence table, the acquired tone color control information is delivered to a tone generator, and desired tone color parameters are set on the basis of the tone color control information. The thus-set tone color parameters will be used for tone color control of performance data generated as the user subsequently executes an actual, formal performance.

Claims

1. A tone color setting apparatus comprising:

a performance input section that inputs performance data based on a performance by a user;

a tendency extraction section that extracts a performance tendency of the user from the performance data inputted via said performance input section;

a feeling detection section that generates feeling information indicative of a mood or feeling of the user presumed on the basis of the performance tendency extracted by said tendency extraction section;

a storage section having tone color control information prestored therein in association with a plurality of kinds of feeling information;

an acquisition section that acquires, from said storage section, tone color control information corresponding to the feeling information generated by said feeling detection section; and

a tone color setting section that sets a tone color parameter on the basis of the tone color control information acquired by said acquisition section.

2. A tone color setting apparatus as claimed in claim 1 which further comprises a model music piece supply section that supplies model music piece data, and

wherein said tendency extraction section compares the performance data, inputted via said performance input section, with the model music piece data, to extract a performance tendency of the user.

3. A tone color setting apparatus as claimed in claim 2 wherein said tendency extraction section compares the performance data, inputted via said performance input section, with the model music piece data about a plurality of kinds of performance evaluation items and generates performance evaluation information for each of the items on the basis of a result of the comparison, to thereby extract the performance tendency of the user.

4. A tone color setting apparatus as claimed in claim 1 wherein said tendency extraction section evaluates the performance data, inputted via said performance input section, about a plurality of kinds of performance evaluation items, to thereby extract the performance tendency of the user.

5. A tone color setting apparatus as claimed in claim 1 wherein said tendency extraction section stores previous performance record data of the user and extracts a current performance tendency on the basis of a comparison between the performance record data and the performance data inputted via said performance input section.

6. A tone color setting apparatus as claimed in claim 1 wherein said feeling detection section generates the feeling information, on the basis of the extracted performance tendency, with reference to a table predefining correspondence between performance tendencies and feeling information.

7. A tone color setting apparatus as claimed in claim 1 wherein said feeling detection section generates the feeling information, on the basis of the extracted performance tendency, by executing a predetermined algorithm for determining a mood or feeling.

8. A tone color setting apparatus as claimed in claim 1 wherein said feeling detection section includes a conversion section that converts information indicative of the performance tendency, extracted by said tendency extraction section, into corresponding feeling information.

9. A tone color setting method comprising:

a step of inputting performance data based on a performance by a user;

a step of extracting a performance tendency of the user from the performance data inputted via said step of inputting;

a step of generating feeling information indicative of a mood or feeling of the user presumed on the basis of the performance tendency extracted by said step of extracting;

a step of acquiring tone color control information corresponding to the feeling information generated by said step of generating; and

a step of setting a tone color parameter on the basis of the tone color control information acquired by said step of acquiring.

10. A computer program, stored on a computer readable medium, containing a group of instructions for causing a computer to perform a tone color setting method, said tone color setting method comprising:

a step of inputting performance data based on a performance by a user;

a step of extracting a performance tendency of the user from the performance data inputted by said step of inputting;

a step of generating feeling information indicative of a mood or feeling of the user presumed on the basis of the performance tendency extracted by said step of extracting;

a step of acquiring tone color control information corresponding to the feeling information generated by said step of generating; and

a step of setting a tone color parameter on the basis of the tone color control information acquired by said step of acquiring.
