FIG. 9 is a flowchart showing the outline of a performance determination process performed in a conventionally used performance learning apparatus. As shown in FIG. 9, in step S101, the user receives performance data (external performance data) together with the performance performed by the performance training apparatus. In step S102, the performance data of the portion corresponding to the external performance data is read from the sequence data for reproduction (a series of music data) using the reproduction pointer. In step S103, the external performance data is compared with the read performance data. For example,
MIDI (Musical Instrument D
The comparison is performed using the note (key press) number in the digital interface.

If the external performance data matches the read performance data, it is determined that the user has correctly pressed the key, and the flow advances to step S104. In step S104, a process when the answer is correct (correct answer process) is performed. As an example of the correct answer process, for example, a correct answer sound is generated.
Alternatively, processing such as advancing the music or accumulating points is performed.

In step S103, if the external performance data does not match the read performance data, it is determined that the user has not correctly pressed the key, and the flow advances to step S105. In step S105, a process for an incorrect answer (NG) is performed. In the case of incorrect answer,
For example, an incorrect sound (NG sound) is generated, or
This is a process of interrupting the performance of the music on the spot and waiting until correct performance data is obtained, or reducing the score.

When the performance determination technique described above is used, the tune does not progress unless the user performs according to the sequence data for reproduction. When such a performance determination technique is used, the performance determination is uniform and other variations of the performance are not allowed, so that the user may not be able to enjoy music and may feel stress.

[0008] For example, when the user is a beginner or tries a difficult song, there is a tendency for a slight mistouch, and if the user does not allow it, the song will not progress. Further, there are cases where the user wants to add a variation to the music and perform it. In such a case, it is not preferable that the progress of the music is hindered.

A performance determination function may be newly added to a conventional musical instrument (for example, a natural musical instrument or a composite device of a natural musical instrument and an electronic musical instrument).

The performance determination process according to the present embodiment will be described with reference to FIGS. Here, an example will be described in which, when one sound of the external performance data is received, a process based on the following flow is performed in response to the reception of the one sound.

First, in step S 1, when the user starts playing a piece of music by operating the operation element 18 such as a keyboard, data corresponding to the operation is generated, and the data is transmitted to the CPU 14 via the bus 11. . When the CPU 14 receives the data, the data is processed, and is stored in the storage device such as the RAM 13 as external performance data.

In step S2, based on the current read / reproduce pointer, sequence data (for example, external storage device 1) including music data serving as a model for one music, for example.
6 is read out of the stored performance data (one tone) corresponding to the external performance data. In step S3, the external performance data is compared with the model read performance data. For example, the comparison is performed using a note (key press) number in MIDI.

If the external performance data matches the read performance data, it is determined that the key has been correctly depressed (input), and the flow advances to step S4 to perform processing for a correct answer (correct answer processing). An example of the correct answer process is to generate a correct answer sound, for example. Alternatively, processing such as prompting the progress of the music by indicating the position of the next key to be depressed by the indicator or accumulating the score is performed. After completing these processes, a series of processes ends in step S5. When the user plays the next part, step S1
And the same process is performed.

Incidentally, as one type of mistouch, a user
It is also conceivable to press more than a note simultaneously. In this case, the data pressed first is received first, but the data pressed later is also received. In such a case, 2
Data corresponding to a sound or three or more sounds can be regarded as one data.

If the external performance data does not match the read performance data in step S3, the process proceeds to step S6. In step S6, training auxiliary data (auxiliary data) is read. The auxiliary data is MI
If it is embedded in the performance data of the sequence data as a DI system exclusive or meta event, it can be read from the read performance data.

In step S7, the externally received data is compared with the auxiliary data. As a result of comparing the externally received data with the auxiliary data, if they match, step S
Proceeding to 4, it is determined that the key has been correctly pressed. In the following, in the step S3, the processing when the answer is correct is performed in the same manner as the processing when the external reception data matches the read performance data.

If it is determined in step S7 that the externally received data does not match the auxiliary data, it is determined that the key has not been correctly pressed, and the flow advances to step S8. In step S8, a process for an incorrect answer (NG) is performed. For example,
Generate an incorrect answer sound (NG sound). Alternatively, the performance of the music is interrupted on the spot, and the process waits until correct performance data is obtained. Alternatively, processing such as deduction of points is performed.

Using the performance determination method described above,
Even if the user does not perform according to the sequence data for reproduction, the tune proceeds if the user performs according to the auxiliary data. As a variation of the performance, a case where the external performance data and the auxiliary data match is also allowed, so that the performance determination is not uniform, and the user can play more happily.

If the auxiliary data is embedded in the performance data of the sequence data as a system exclusive or meta-event in the performance data of the sequence data, a normal device (such as a normal electronic musical instrument or player) that cannot use the auxiliary data. In, the auxiliary data can be simply skipped. When the performance is performed using a normal device, the auxiliary data is simply ignored and does not harm the normal performance.

Next, a performance determination technique according to a first modification of the performance determination technique according to the first embodiment of the present invention will be described with reference to FIG. In the performance determination technique shown in FIG. 3, n different auxiliary data from 1 to n (n is an integer of 2 or more) are prepared as auxiliary data corresponding to one piece of external performance data. The processing from step S11 to step S13 is the same as the processing from step S1 to step S3 in FIG. Step S13
If the externally received data does not match the read performance data at step S16, the process proceeds to step S16, where the first auxiliary data of the plurality of training auxiliary data included in the performance data is read.

In step S17, the externally received data is compared with the first auxiliary data. As a result of comparing the externally received data with the first auxiliary data, if they match, it is determined that the key has been correctly pressed, and the process proceeds to step S14. Hereinafter, as in the case where the external reception data and the read performance data match in step S13,
Perform the process when the answer is correct.

If the externally received data does not match the first auxiliary data in step S17, the process proceeds to step S18. In step S18, second auxiliary data for training is read from the performance data.

In step S19, the external reception data is compared with the second auxiliary data. As a result of comparing the externally received data with the second auxiliary data, if they match, it is determined that the key has been correctly pressed, and the process proceeds to step S14. Hereinafter, as in the case where the external reception data and the read performance data match in step S13,
Perform the process when the answer is correct.

If the external performance data and the performance data do not match, the same processing is performed using the third, fourth,... Auxiliary data.

If the discrepancy between the external performance data and the auxiliary data continues in the comparison step, the n-th auxiliary data, which is the last auxiliary data for training, is finally obtained from the performance data as shown in step S20, for example. Is read. In step S21, the external reception data and the n-th
With the auxiliary data of As a result of comparing the externally received data with the n-th auxiliary data, if they match, it is determined that the key has been correctly pressed, and the flow proceeds to step S14. In the following, in the step S13, the processing when the answer is correct is performed in the same manner as the processing when the external reception data and the read performance data match.

In step S21, if they do not match, it is determined that the key has not been pressed correctly, and
Proceed to 22. In step S22, an incorrect answer (NG)
The processing in the case of is performed.

Using the performance determination method described above,
Even if the user does not perform according to the sequence data for reproduction, the tune proceeds as long as the user performs in the same manner as any one of the plurality of prepared auxiliary data. Since the tolerance of the performance variation is further increased, the user can perform the performance more happily.

Next, a performance determination technique according to a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, correct key depression sound data is calculated by performing arithmetic processing using read performance data and auxiliary data. The calculated data is compared with the externally received data.

First, in step S31, external performance data played by the user is received. Step S
At 32, the performance data (read performance data) is read from the sequence data using the current read / play pointer.
Read out one of the sounds. In step S33, the external performance data is compared with the read performance data.

If the two match, it is determined that the key has been correctly pressed, and the flow advances to step S34 to perform processing for a correct answer (correct answer processing). In step S35, the process for one sound ends. The same processing is performed again on the next sound from step S31.

If the performance data of the user does not match the read performance data in step S33, the process proceeds to step S36. In step S36, auxiliary data for training is read.

In step S37, a predetermined logical operation is performed using the sequence data and the auxiliary data.
A correct key depression sound is calculated as a result of the predetermined logical operation processing.

The logical operation will be described. For example,
At the corresponding location in the performance data,
Data [1, 1] is embedded as an exclusive or meta event. The arithmetic processing of the auxiliary data [1, 1] and the pitch data of the read sequence is performed, for example, as shown in step S37, by (pitch data NN of the read sequence) −1 and (pitch of the read sequence). This is an arithmetic process for calculating (data NN) +1.

In step S38, based on the calculated data, a conditional expression: (pitch data of read sequence) NN-1 << = external reception data << = (pitch data of read sequence) NN + 1 It is determined that the external reception data and the calculated key press sound data match (ie, are within a predetermined range). As a result of comparing the externally received data with the calculated key press sound data, if they match, it is determined that the key has been pressed correctly, and the process proceeds to step S34. In the following, in the step S3 (FIG. 2), the processing when the answer is correct is performed in the same manner as the processing when the external reception data and the read performance data match.

If it is determined in step S38 that the externally received data does not match the calculated key depression sound data, it is determined that the key is not correctly depressed, and the flow advances to step S39. In step S39, a process for an incorrect answer (NG) is performed.

Using the performance determination method described above,
Even if the user does not perform according to the sequence data for reproduction, if the user falls within the range of the predetermined pitch data, the user is allowed to perform the music. Since mistouch (allowing a nearby key to be pressed by mistake) is allowed within a certain range, the user can continue playing happily even with a song having a high degree of difficulty.

The allowable range can be adjusted by changing the auxiliary data according to the difficulty level of the music.

As in the case of the performance judging technique according to the first embodiment, the performance judging device according to the present embodiment also reads out any one of a plurality of auxiliary data and reads the sequence data. Is performed, and the externally received data is compared with the calculated key press sound data. If the two do not match, the second auxiliary data may be read next to perform the same operation. . Also,
Only one auxiliary data may be prepared, a plurality of arithmetic processing methods may be prepared, and the comparison may be performed stepwise. In accordance with this, the processing in the case of the correct answer may be divided into ranks, for example, the rank may be classified according to the increase in the score.

Next, a performance determining technique according to a third embodiment of the present invention will be described with reference to FIGS.

FIG. 5 is a flowchart showing a performance determination processing flow used in a performance determination technique according to a modification of the third embodiment of the present invention. FIG. 6A is a schematic diagram showing the data structure of auxiliary data used in the performance determination processing, and FIG. 6B shows, for example, the logic I in one music.
It is a figure showing an example of how to allocate D.

The flow of performance determination according to the present embodiment will be described. In this flow, when two or more fixed parts of the sound are received from the external performance data, processing based on the following flow is performed in response to the reception of the fixed part of the sound.

First, in step S41, the performance training apparatus receives external performance data (including two or more sounds) played by the user. In step S42, performance data (read performance data) is read from the sequence data using the current read / play pointer. Step S
At 43, the external performance data is compared with the read performance data.

If the two match, it is determined that the key has been correctly depressed, and the flow advances to step S44 to perform processing for a correct answer (correct answer processing). After completing the correct answer process, a series of processes ends in step S45. The same processing is performed again from step S41.

If it is determined in step S43 that the user performance data does not match the read performance data, the flow advances to step S46. In step S46, auxiliary data for training (auxiliary data) is read from the read performance data.

In step S47, a process based on the specified logic ID is performed. As a result of the process based on the logic ID, a correct key depression sound is calculated.

As shown in FIG. 6A, auxiliary data including logic ID data is stored as a system exclusive or meta event. The byte count following the header indicates the byte size until the end of the data. The logic ID is, for example, an ID from “0” to “3”. The data area includes data 1 to n (n is an integer of 2 or more) that are comparison candidates with the externally received data in step S47.

The logic ID is specified, for example, as follows.

If the logic ID is "0", the performance determination processing is not performed. The logic ID “0” designates a part of the music that is not evaluated for performance. If the logic ID is "1", any of the data 1 to n and the external performance data are directly compared. Note that n can be calculated until the data end ID is detected or from the byte count.

When the logic ID is "2", two data, data 1 and data 2, stored in the data area are read out, and a determination is made based on the following equation.

(Read Data) − (Data 1) <= External Received Data <= (Read Data) + (Data 2) (1) If the value falls within the range of the above expression (1), in step S 47, the external reception It is determined that the data and the auxiliary data match.

Further, a case where the logic ID is "3" is prepared. If the logic ID is 3, a logic different from the above equation (1) can be added as an option.

As shown in FIG. 6B, if a logic ID value is assigned to each station part, a different judgment can be made for each part.

In step S47, if the above conditions are satisfied, it is determined that the externally received data matches the calculated key press sound data.

In step S47, as a result of comparing the externally received data with the calculated key press sound data, if they match, it is determined that the key is pressed correctly, and the flow advances to step S44. In the following, in the step S3 (FIG. 2), the processing when the answer is correct is performed in the same manner as the processing when the external reception data and the read performance data match.

If the logic ID is "0", the flow directly proceeds to step S45 in order to determine whether the external performance data matches the auxiliary data or not.

If it is determined in step S47 that the externally received data does not match the key press sound data referred to in the auxiliary data, it is determined that the key has not been pressed correctly, and the flow advances to step S48. In step S48, an incorrect answer (N
The processing in the case of G) is performed.

Using the performance determination method described above,
Even if the user does not play the part of the music according to the sequence data for reproduction, the user is allowed to perform the music as long as the conditions defined by the predetermined logic ID are satisfied. Since mistouch (allowing a nearby key to be pressed by mistake) is allowed within a certain range, the user can continue playing happily even with a song having a high degree of difficulty.

The allowable range can be adjusted by changing the auxiliary data according to the difficulty level of the music.

In the above-described embodiment, an example in which the logic ID is changed for each part of the music has been described. However, the logic ID is not changed for each part of the music.
The logic ID may be changed for each part, for example, between the main melody part and the accompaniment part, or may be changed for each part and the logic ID may be changed for each part.

Further, in the performance judging devices according to the first to third embodiments, the step of comparing the externally received data with the read-out performance data is omitted, and the auxiliary data, the calculated data and the externally received data are immediately replaced. May be performed.

FIG. 7 shows a flowchart of the data conversion processing in this case.

As shown in FIG. 7, in step S51, external performance data played by the user is received. Step S
At 52, training auxiliary data is read from the performance data. In step S53, the external reception data is compared with the auxiliary data. If they match, the process proceeds to step S54, and processing for a correct answer is performed. Proceeding to step S55, the first data processing ends. If the external reception data and auxiliary data do not match in step S53, the process proceeds to step S56. Step S5
In step 6, it is determined that the key is not correctly depressed, and processing for an incorrect answer is performed. Proceeding to step S55, the first data processing ends.

In this case, the step of comparing the externally received data with the read performance data is omitted, and the auxiliary data and the calculated data are immediately compared with the externally received data.
The processing steps are simplified.

In the above-described performance data conversion technique,
If there is no auxiliary data or the like, a comparison step between the externally received data and the read performance data may be performed.
However, if the step of comparing the externally received data with the read performance data is omitted, it is possible to separate a portion of the performance data where performance determination (evaluation) is performed and a portion where performance determination (evaluation) is not performed in note units. That is, in one song or one part,
A certain note has both readout performance data and auxiliary data, and another note has only readout performance data, or another note has only auxiliary data. It is also possible to form a data structure as described above.

Referring to FIG. 8, a description will be given of a performance determination technique according to a fourth embodiment of the present invention. FIG. 8 shows an example of a data configuration in which auxiliary data is inserted into performance data of an actual performance. The auxiliary data includes a section length (clock count number), a target part, a variation number, and at least one variation sound sequence group.

The section length indicates the length of a section defined in units of a quarter note divided into 128. By setting such fine divisions as one unit, sufficient accuracy can be provided. The target part, for example, when having a plurality of channels, specifies which channel is to be targeted. The variation number n defines the number of variation sound sequence groups. The variation sound string group includes at least one sound, and usually includes a sound string in one phrase. The characteristic of the performance data shown in FIG. 8 is that the performance data is divided into predetermined sections, for example, one section for each predetermined phrase, and auxiliary data is inserted between adjacent phrases.

For example, when the read pointer detects the auxiliary data existing at the position shown in FIG. 8, the target is the number of clock counts (indicating the section length) specified in the auxiliary data. The external reception data received in the part is stored in a RAM or the like with time intervals.

Thereafter, the external reception data is compared with the variation sound sequence groups 1 to n to determine whether or not both match. In the variation sound string groups 1 to n, for example, other regular phrases that are different from the regular phrases but can be replaced with the regular phrases can be stored.

When the performance determination is performed using the performance data and the auxiliary data as described above, even if the user replaces the regular phrase with another regular phrase, for example, it is determined that the user has performed correctly. Will be judged.

The variation sound sequence group may include note numbers (pitch) and time interval data, but may include only note numbers and do not have time interval data.
