  In the above-mentioned conventional apparatus, when it is desired to select and use (playback / practice) the same song data as the song data selected before the power is turned off after the power is turned off, the directory of the target song data is deep. If this is recorded, the operation until the path to the data is set is complicated. In addition, when the medium is replaced, it is necessary to select again the song data that was previously used on the replaced medium.

  With the technology used in the above karaoke device, even if the power is turned off, the backup of the path to the song data used immediately before the power is turned off is taken, but the configuration of the storage device has changed or the media has been replaced. I couldn't cope with the case.

  As described above, in the conventional apparatus, when the power is turned off and then turned on again, or when the medium is replaced, it is necessary to select the previously selected music piece data again. For example, in a music classroom, when practicing for several days using the same song data, it is necessary to select the same song data every day. However, such an operation is cumbersome, especially when the user is a machine such as a young person. If the user is unfamiliar with the operation, the music data selection operation is often difficult.

  An object of the present invention is to provide an electronic music apparatus capable of easily selecting song data.

  According to an aspect of the present invention, an electronic music device includes a reading unit that reads music content data from a recording medium having an identifier, a first detection unit that automatically detects a reading instruction for music content data, and a user According to a second detection means for detecting a music content data read instruction, and a music content data read instruction detected by the second detection means, the read means is controlled to read the music content data, Registration means for registering information specifying the read music content data in association with an identifier of the recording medium on which the read music content data is recorded, and the first detection means issues a read instruction for music content data. When automatically detected, from the currently available recording medium, Search means for searching for music content data that matches information registered in the recording means; and when the search means detects music content data that matches information registered in the registration means, Control means for controlling the reading means so as to read.

The backup buffer is a predetermined area reserved in the storage device 15 of FIG. 1 for recording registration information (specific information and media ID and rank information associated with the specific information).

  In the backup buffer, in order to specify music data, registration information including specific information and media ID and rank information associated with the specific information is recorded for each music data. The specific information is a path or song number indicating the recording location (folder, directory, etc.) of the song data. The media ID is an identifier assigned to each medium 16 in order to identify the recording medium (medium) 16 on which the song data specified by the specific information is recorded. The rank information is information indicating a priority rank in automatic selection of music data. The path is represented by a drive name, a folder name, and a file name of music data, for example, “drive name: / folder name / file name”. If a file is recorded in the root folder of the drive, the folder name is omitted.

  The embodiment of the present invention is loaded immediately before power-up of the electronic music apparatus 100 and when the medium 16 is replaced (before the previous power-off or when the medium 16 inserted by replacement has been inserted last time). The song data is automatically selected and read out, and every time the song data is read out, the specific information of the song data is stored in the backup buffer, and when the power is turned on or the medium 16 is replaced, Automatically load song data using registration information. Note that if the registration information (excluding the order information) does not completely match, automatic loading is not performed, but song data that matches the registration information other than the drive name (excluding the order information) is automatically loaded. May be.

  In the example shown below, two pieces of registration information are recorded in the backup buffer, but the present invention is not limited to this.

  In the following example, only the case of selecting music data will be described, but the same applies to the case of selecting other data such as a management file.

  FIG. 2A is a conceptual diagram showing the state of the backup buffer in the initial state (when shipped from the factory or when the user performs buffer initialization operation). In the initial state, the media ID, the song data path (specific information), and the rank information are all “empty”. Thereafter, for example, when the medium 16 with the media ID “AAA” is inserted into the E drive and the song data with the file name “Song1” under the root directory is selected, as shown in FIG. “AAA” that is an identifier of the medium 16 is recorded in the media ID, and “E: / Song1” that is a path for specifying the music data is recorded in the music data path. Also, “1” is recorded in the rank information. In this state, when the power is turned off and turned on again, the song data of the path “E: / Song1” is automatically loaded according to the contents recorded in the backup buffer. In this state, when the medium 16 is replaced, automatic loading is not performed.

  Next, when the medium 16 of the E drive is replaced, the medium 16 assigned with the medium ID “BBB” is inserted, and the song data with the file name “Song2” under the root directory is selected, FIG. ), A media ID “BBB”, a song data path (specific information) “E: / Song2”, and rank information “1” are newly added to the backup buffer. At this time, the previously recorded order information of the medium ID “AAA” and the song data path “E: / Song1” is rewritten to “2”. In this state, when the power is turned off and then turned on again, the song data of the path “E: / Song2” whose rank information is “1” is automatically loaded according to the contents recorded in the backup buffer. . When the media 16 of the E drive is replaced with the media ID “AAA” again, the media ID “AAA” recorded in the rank information “2” and the song data path “E: / Song1” are automatically loaded. Is done. At this time, when the medium 16 having the media ID “AAA” other than the E drive is inserted into the F drive, for example, the media IDs of the drives whose names do not match are the same, so that “F: / Song1” Load song data automatically. That is, if the information other than the drive name matches even if the drive name is changed, automatic loading is performed. As a result, the specific information related to the media ID “AAA” in the backup buffer is rewritten to “F: / Song1”, and the order information is also rewritten to “1”. In this state, when a medium 16 other than the medium ID “AAA” or “BBB” is inserted, the music data is not automatically loaded.

  Next, when the song data with the file name “Song3” under the root directory is selected in the state where the media 16 with the media ID “AAA” is inserted in the F drive, the registration information with the same media ID is newly registered. Overwritten with registration information. That is, the specific information of the media ID “AAA”, the song data path “F: / Song1”, and the rank information “1” includes the media ID “AAA”, the song data path “1”, as shown in FIG. F: / Song3 ”and the order information“ 1 ”are overwritten. At this time, the rank information of the specific information of the media ID “BBB” and the song data path “E: / Song2” is rewritten to “2”. In this state, when the power is turned off and then turned on again, the music data of the path “F: / Song3” having the priority “1” is automatically loaded according to the contents recorded in the backup buffer. . Further, when the medium 16 with the medium ID “BBB” is inserted into any of the drives, “Song2” under the root directory of the drive in which the medium 16 is inserted is automatically loaded. In this state, when a medium 16 other than the medium ID “AAA” or “BBB” is inserted, the music data is not automatically loaded.

  If another song data recorded on the medium 16 having the same media ID as the song data whose registration information is already recorded in the backup buffer is selected, the song of the same media already recorded is selected. Regardless of the rank information recorded in the registration information of the data, the registration information of the song data of the same medium is overwritten with the registration information of the newly selected song data.

  Next, when the medium 16 with the medium ID “CCC” is inserted into the G drive and the song data with the file name “Song 4” under the root directory is selected, as shown in FIG. Registration information of ID “CCC”, song data path “G: / Song4”, and rank information “1” is generated, and the registration information with the lowest rank (“2” in this example) is overwritten. At this time, since the new registration information becomes the rank information “1”, the rank of the other registration information is lowered one by one. As described above, when the song data recorded on the medium 16 having the media ID not currently recorded in the backup buffer is selected, the registration information having the lowest rank is overwritten with the new registration information.

  In the present embodiment, even if some music data is being selected, the medium 16 on which the music data that matches the registered information recorded in the backup buffer (including the case other than the drive name matches) is inserted. Then, the music data recorded on the medium 16 is automatically read out.

  In this embodiment, the loading of music data is to read the music data from the medium 16 to the reproduction buffer provided in the RAM 7 or the storage device 15 in FIG. If the music data includes setting data of the electronic music apparatus 100 such as timbre setting data, the setting based on the setting data may be automatically performed after the music data is loaded.

  If the song data type is built-in song data built in the electronic music apparatus 100 in advance, the song number may be recorded as specific information instead of the path. In the case of a management file, the path information may be recorded with the path of the song data being selected in the management file, and the path of the management file and the song data being selected are recorded in the management file. You may make it record according to whether it is data.

  If the music data exists on the network, the media ID may be omitted and the network path, URL, etc. may be recorded.

  3 and 4 are flowcharts showing a main process of the electronic music apparatus 100 according to the embodiment of the present invention.

  In step SA1, the main process is started by turning on the electronic music apparatus 100. In step SA2, it is determined whether registration information corresponding to the currently valid medium 16 (FIG. 1) is stored in the backup buffer. Here, the effective media 16 is the media 16 that can be read by the storage device 15 or the external storage device 51 of FIG. 1 (including the case where the media 16 inserted into the drive and the drive and the media are integrated). . This determination is made by comparing the media ID of the currently valid media 16 with the media ID stored in the backup buffer. If stored, the process proceeds to step SA3 indicated by an arrow of YES, and if not stored, the process proceeds to step SA13 of FIG. 4 indicated by an arrow of NO.

  In step SA3, it is determined whether there is one registration information stored in the backup buffer detected in step SA2. If there is one, the process proceeds to step SA4 indicated by an arrow of YES, and if there are two or more, the process proceeds to step SA8 indicated by an arrow of NO.

  In step SA4, it is determined whether or not music data that matches the registration information stored in the backup buffer detected in step SA2 is stored in the location indicated by the specific information in the registration information. If song data matching the registered information is stored in the location indicated by the specific information, the process proceeds to step SA5 indicated by a YES arrow. If not, the process proceeds to step SA6 indicated by a NO arrow.

  In step SA5, the music data detected in step SA4 is selected and read (loaded) into the RAM 7 in FIG. 1, the reproduction buffer in the storage device 15, or the like. Thereafter, the process proceeds to step SA20 in FIG.

  In step SA6, it is determined whether or not song data that matches the specific information of the registered information stored in the backup buffer detected in step SA2 except for the drive name is stored in the currently valid medium 16. If stored, the process proceeds to step SA7 indicated by an arrow of YES, and if not stored, the process proceeds to step SA13 of FIG. 4 indicated by an arrow of NO.

  In step SA7, the music data detected in step SA6 is selected and read (loaded) into the RAM 7 in FIG. 1, the reproduction buffer in the storage device 15, or the like. Thereafter, the process proceeds to step SA20 in FIG.

  The following steps SA8 to SA12 are processing when it is determined in step SA3 that there are two or more pieces of registration information stored in the backup buffer detected in step SA2.

  In step SA8, reference is made to the rank information of the registration information stored in the backup buffer detected in step SA2, and the pieces of music data having the same registration information in order from the top rank for the media 16 indicated by the media ID of each registration information. Is stored in the location indicated by the specific information in the registration information.

  In step SA9, it is determined whether or not music data whose registration information matches is detected in step SA8. If detected, the process proceeds to step SA12 indicated by an arrow of YES, and if not detected, the process proceeds to step SA10 indicated by an arrow of NO.

  In step SA10, the backup information detected in step SA2 is referred to in order from the top of the media 16 indicated by the media ID of each registration information with reference to the ranking information of the registration information stored in the backup buffer detected in step SA2. It is determined whether or not the music data whose specific information other than the drive name matches the specific information in the registration information stored in is stored in any currently valid medium 16.

  In step SA11, it is determined whether or not music data in which registration information other than the drive name matches is detected in step SA10. If detected, the process proceeds to step SA12 indicated by an arrow “YES”, and if not detected, the process proceeds to step SA13 in FIG. 4 indicated by an arrow “NO”.

  Reference is now made to FIG.

  In step SA13, it is determined whether or not a power-off instruction is input to the electronic music apparatus 100. If power-off is instructed, the process proceeds to step SA21 indicated by a YES arrow to end the main process and turn off the electronic music device 100. Note that the contents of the backup buffer are retained even after the power is turned off. If there is no instruction to turn off the power, the process proceeds to step SA14 indicated by a NO arrow.

  In step SA14, the removal of the effective medium 16 is detected. When the media 16 is disconnected from the drive 15 or 51, or when the connection to the communication I / F 21 of the drive 51 is cut off or the power supply is cut off, the valid media 16 cannot be accessed. In this case, the process returns to step SA13 indicated by a YES arrow. If not detected, the process proceeds to step SA15 indicated by a NO arrow.

  In step SA15, the insertion of the medium 16 is detected. When access to the media 16 is enabled when the media 16 is inserted into the drive 15 or 51, or when the drive 51 is connected to the communication I / F 21 or powered on, the arrow of YES The process proceeds to step SA16. If not detected, the process proceeds to step SA17 indicated by a NO arrow.

  In step SA16, it is determined whether or not the media ID of the media 16 detected to be valid in step SA15 is already included in the registration information stored in the backup buffer. If included, the process proceeds to step SA4 in FIG. If not, the process returns to step SA13 indicated by a NO arrow.

  In step SA17, a music selection operation by the user is detected. The music selection operation by the user is performed, for example, by operating the setting operator 12 with reference to a list of music data displayed on the display 14 of FIG. When the music selection operation is detected, the process proceeds to Step SA19 indicated by an arrow of YES. If not detected, the process proceeds to step SA18 indicated by a NO arrow.

  In step SA18, other processing in the electronic music apparatus 100 is performed. Here, the other processing includes, for example, music data management (save operation, deletion operation, other file management), performance operation and sound processing associated therewith, processing specific to the electronic music apparatus, loaded music data Execution or start of reproduction processing, sound generation processing, performance training processing, performance guide processing, etc. (when the processing is interrupt processing or the like). Thereafter, the process returns to step SA13.

  In step SA19, the music data selected by the music selection operation detected in step SA17 is loaded from the medium 16. Thereafter, the process proceeds to step SA20.

  In step SA20, a process for registering the registration information of the song data selected and loaded in step SA19, step SA5, SA7 or SA12 in FIG. 3 in the backup buffer is performed. Details of the processing here are shown in FIG. Thereafter, the process returns to step SA13.

  FIG. 5 is a flowchart showing the registration process to the backup buffer executed in step SA20 of FIG.

  In step SB1, registration processing is started. In step SB2, music data selected and loaded in step SA19 in FIG. 4 or steps SA5, SA7 or SA12 in FIG. 3 (hereinafter simply referred to as “selected music data”). Specific information is newly generated based on the type (file name and extension, etc.), path, or song number, and is set as NewData.

  In step SB3, it is determined whether or not the media ID of the media 16 in which the selected song data is stored is included in the registration information in the backup buffer. If it is included, the process proceeds to Step SB4 indicated by a YES arrow, and if it is not included, the process proceeds to Step SB6 indicated by a NO arrow.

  In step SB4, the rank information corresponding to each medium ID higher than the rank information corresponding to the medium ID determined to be included in the registration information in the backup buffer in step SB3 (the rank information value is larger). Each of the displayed ranks is moved backward by 1 ("1" is added to the rank information value).

  In step SB5, the specific information NewData generated in step SB1 is associated with the media ID determined to be included in the specific information in the backup buffer in step SB3, the value of the rank information is set to “1”, and the registration information is set. Generate and store in backup buffer. At this time, the registration information including the media ID determined to be included in the registration information in the backup buffer in the previous step SB3 is overwritten with the new registration information. Thereby, for one media ID, only one registration information is recorded in the backup buffer. Then, it progresses to step SB10 and complete | finishes a registration process.

  In step SB6, the ranks indicated by the rank information corresponding to the respective media IDs stored in the backup buffer are each moved backward by one (adding “1” to the rank information value).

  In step SB7, it is determined whether or not new registration information can be additionally registered in the backup buffer. If additional registration is possible, the process proceeds to step SB9 indicated by a YES arrow, and if not, the process proceeds to step SB8 indicated by a NO arrow.

  In step SB8, the rank information of each registration information already stored in the backup buffer is referred to, and the registration information whose rank is the last (the rank information value is maximum) is deleted from the backup buffer.

  In step SB9, the specific information NewData generated in step SB1 is associated with the media ID determined not to be included in the specific information in the backup buffer in step SB3, the value of the rank information is set to “1”, and the registration information is set. Generate and register additional in the backup buffer. Then, it progresses to step SB10 and complete | finishes a registration process.

  As described above, according to the embodiment of the present invention, the registration information recorded in the backup buffer is overwritten with the newly selected registration information. Therefore, when the power is turned off and then turned on again, the song data before the power is turned off. Etc. can be loaded automatically. That is, in the embodiment of the present invention, when the electronic music apparatus 100 is turned on (start of the main process in step SA1 in FIG. 3) or the medium insertion detection in step SA15 in FIG. In step SA5, SA7 or SA12 in FIG. 3, the music data is automatically read out.

  In addition, since a plurality of registration information can be recorded in the backup buffer, when the medium 16 is replaced, music data previously selected on the medium 16 can be automatically loaded.

  In this embodiment, only two pieces of registration information are recorded, but more registration information may be recorded. By doing so, for example, in a music classroom where there are many students, the media 16 can be used properly for each student, and the song data used last time can be automatically loaded for each student.

  In the present embodiment, it has been described that the data to be automatically loaded is music data, but the data to be loaded is not limited to this, but for training data such as fingering information, automatic accompaniment data, score data, etc. Alternatively, various music content data such as a combination of these and song data corresponding to these data can be automatically read out.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto.
