When input sound information played with an open string by a user who has seen this performance instruction is sent from the external input unit 130, the input sound information is stored in the RAM 102. When the input sound information is stored in the RAM 102, the application is terminated and the process proceeds to step 112.

  In step S112, the pitch of the input sound information stored in the RAM 102 in step S111 is analyzed, and the type of instrument is specified. The input sound information is Fourier transformed, and a plurality of frequencies corresponding to the sound represented by the input sound information are extracted. A plurality of pitches are identified from frequencies that exceed a predetermined level among the extracted frequencies. The frequency exceeding a predetermined level distinguishes the frequency represented by the sound produced by each string from the frequency represented by the overtone that appears when the instrument is played, and represents the frequency represented by the sound produced by each string. First, the number of strings of the musical instrument is specified from the specified number of pitches. When the number of strings is specified, the extracted pitches are compared with the instrument identification table and whether the pitch is a basic tune or a tune shifted by a semitone from the pitches corresponding to the number of strings. The type of tuning method is specified. Furthermore, the type of musical instrument is specified according to the specified number of strings and tuning method. Generally, an electric guitar and an electric bass are configured such that the electric bass produces a sound one octave lower than the electric guitar. Therefore, even if the number of strings and the chord representing the tuning method are the same between the electric guitar and the electric bass, the type of musical instrument can be identified. As an example, when the extracted pitches are “E, B, G, D, A, E” and “A” is a frequency near 110 Hz, it corresponds to the sound represented by the input sound information. The instrument is determined to be a 6-string electric guitar. In addition, when the extracted pitches are “E, B, G, D, A, E” and “A” is a frequency near 55 Hz, the musical instrument corresponding to the sound represented by the input sound information Is determined to be a 6-string electric bass. When the type of instrument is determined, instrument identification information corresponding to the name of the instrument, the number of strings, and the tuning method is determined, and the process proceeds to step S113.

  In step S113, the instrument identification information determined in the process of step S112 is stored in the RAM 102 in association with the channel identification information corresponding to the channel of the external input unit 130 to which the instrument corresponding to the instrument identification information is connected. When the musical instrument identification information and the channel identification information are stored in the RAM 102 in association with each other, the subroutine process started in step S110 is terminated.

[Modification 1]
In step S <b> 111, input sound information when the user has tuned the musical instrument with an open string is stored in the RAM 102. In step S112, the pitch of the input sound information stored in the RAM 102 is analyzed, and the type of instrument is specified. However, in step S111, input sound information representing the performance sound of the musical instrument while the user is tuning or trial performance may be stored. In this case, in the process performed in step S112, the number of strings is specified from the number of specified pitches, and the electric guitar or electric bass is specified from the frequency range representing the pitches. As an example, the frequency representing the range of a general electric guitar is about 31 Hz to 523 Hz, and the frequency representing the range of a general electric bass is about 41 Hz to 196 Hz. The type of instrument is specified by the difference in the frequency range. At this time, the instrument identification information may be information of a number consisting only of the name of the instrument or information of a number consisting of the name of the instrument and string information. Furthermore, in order to specify the type of tuning method, it is necessary to specify input sound information representing a performance sound with an open string or input sound information representing a performance sound performed under certain conditions described later. There is. Therefore, the instrument identification table corresponding to the condition needs to be stored in the instrument identification table storage area 116 in advance.

[Modification 2]
The instrument identification table for specifying the instrument may store a chord that is unified when played under certain conditions, not a chord representing the pitch of an open string. As an example, it may be a table in which a chord representing a performance sound in which the second fret of the first string is pressed is stored. However, the input sound information representing the performance sound stored in step S111 must be input sound information when the second fret of the first string is pressed. That is, when a performance instruction including a condition is displayed on the display 201 and input sound information performed according to the condition is transmitted from the external input unit 130 by the user who has viewed the performance instruction, the input sound information is stored in the RAM 102.

[Modification 3]
In the embodiment, the performance information is information representing the performance sound of the musical instrument played by the user, but may be associated with moving image information representing the performance state of the user. The music reproducing device 1 includes a camera (not shown) in FIG. 1, and information on a moving image photographed by the camera and performance information are associated with each other and stored in the performance information storage area 113. In step S220, performance information is read together with moving image information, and the moving image information is sent to the video RAM 120. In step S230, a reproduction instruction is sent to the audio control unit 140 and the video reproduction unit 121, and the video reproduction unit 121 reads and reproduces the information of the moving image stored in the video RAM 120 according to the reproduction instruction.

[Modification 4]
In the performance instrument specifying process executed in step S150, the instrument identification information associated with the channel identification information of the channel to which the input sound information is input is read. However, the process of step S112 may be executed based on input sound information when the user plays the instrument with an open string. In that case, first, a process of storing input sound information representing a performance sound when an instrument is played with an open string is executed in the same manner as the process executed in step S111. Specifically, an instruction is given so that a performance instruction for performing with an open string is displayed on the display 201. Information representing the contents of the performance instruction is read from the storage unit 110 and sent to the video control unit 122. When the input sound information when the user who has seen the performance instruction plays with an open string is sent from the external input unit 130, the input sound information is stored in the RAM 102. And the process of step S112 is performed. About the process of step S112, since the process similar to embodiment is performed, the description is abbreviate | omitted.

[Modification 5]
In step S120, it is determined whether or not a request to end the musical instrument performance mode is sent from the operation processing unit 150. However, the musical instrument performance mode process may be terminated when there is no user ID stored in association with the login information, or when all the channels of the external input unit 130 are OFF for a predetermined time. When there is no user ID stored in association with the login information, or when the OFF state is continued for a predetermined time in all channels of the external input unit 130, the instrument performance mode processing shown in FIG. Is terminated. Thus, the user can end the process only by releasing the connection of the musical instrument. Therefore, the user can reduce the trouble of operating the operation unit 151 and sending a mode end request to the control unit 100.

[Modification 6]
The process of step S150 may not be executed when there is only one instrument connected to the external input unit 130. If there is only one instrument, the instrument identification information associated with the channel identification information of the channel in the ON state may be read from the RAM 102.

[Effect of this embodiment]
The process of storing the musical instrument identification information and the channel identification information in association with each other in the RAM 102 in step S113 and the process of identifying the musical instrument to be played in step S150 can reduce the process of identifying the musical instrument. These processes also reduce the user's operation of selecting the type of musical instrument for each performance. Further, the music reproducing apparatus performs the processes of steps S160 and S170, or steps S160, S210, and S220. Musical instrument performance can be practiced during the processing time.

  In step S100, it is determined whether there is a channel whose state information has changed from the OFF state to the ON state. As a result, the process of step S110 is executed regardless of whether the connected musical instrument is changed or the same musical instrument as that before being turned off is connected. Thereby, the musical instrument identification information corresponding to the type of the connected musical instrument is always updated with the latest musical instrument identification information, and performance information can be extracted more correctly.

  The instrument identification information is information of a number representing the type of instrument including the name of the instrument, transposition information, and string information. Therefore, the musical instrument can be identified in more detail than the musical instrument is identified only by the name of the musical instrument.
