Description

  The present invention relates to an electronic music apparatus such as an electronic musical instrument in which a display method of information indicating music data files and folders is improved with respect to a display having low display performance.

  Conventionally, some electronic music devices such as electronic musical instruments have a character display with low display performance, and when selecting music data files such as music data, file names expressed in kana, kanji, alphabet, etc. Can not be displayed on the display unit, the file number is displayed instead to select a music data file. For example, in an electronic musical instrument called “MODUS H11” shown in Non-Patent Document 1, a song number that designates a preset song or a song in a USB flash memory is displayed on a three-digit one-line display with seven segments with dot segments. (Pages 17-18, 20-21), when selecting a desired song from a large number of preset songs (performance data) built into this instrument, each song and song number (song number) are previously set. By preparing an associated list, the user can recognize the number of the song to be selected (pages 48-49).

  However, in the case of selecting a music data file in the USB flash memory, the user can save or delete the music data created by the user or purchase the music data from a website or the like at any time in the USB flash memory. If the music data is increased or decreased, the file and the displayed number cannot be associated in advance. Therefore, such files are automatically sorted by some method such as ascending / descending order of file names. For example, when the files are automatically sorted in ascending order of file names, “001” and “002” are sorted in the sort order. , ... etc., will be displayed as numbers. The same situation also occurs with folders when music data files are managed as folders in the USB flash memory.

And this sort of sorting has the following problems that make it difficult for the user to select the desired file:
(1) When the user wants to select specific data (file or folder), he / she does not know which number should be selected (that is, the number cannot be specified from the data).
(2) The number changes each time data is added or deleted, or the data name (file name or folder name) is changed. Even if a previously selected number is selected, data different from the previous one is selected. (That is, the data cannot be specified from the number).

The other part of the example of the next file display processing flow by one Example of this invention is shown.

[Hardware configuration example]
FIG. 1 is a hardware configuration example of an electronic music apparatus according to an embodiment of the present invention. An electronic music apparatus according to an embodiment of the present invention typically uses a dedicated music device such as an electronic musical instrument, and includes a central processing unit (CPU) 1, a random access memory (RAM) 2, and a read only memory (ROM). ) 3, a performance operation detection circuit 4, a setting operation detection circuit 5, a display circuit 6, a sound source / effect circuit 7, a communication interface (communication I / F) 8 and the like. Connected to each other.

  The CPU 1 that controls the entire apparatus, together with the RAM 2 and the ROM 3, constitutes a data processing unit that executes various processes according to various control programs, executes various processes according to various control programs, and performs file / folder display selection processing. Various judgments and controls for determining the display method are performed. The RAM 2 stores various data necessary for these processes, and is used to temporarily hold data as a current buffer. In the ROM 3, various control programs including a file / folder display selection processing program, necessary control data (for example, a sort table), and various data (for example, preset performance data) are stored in advance.

  The performance operation detection circuit 4 constitutes a performance operation section together with a performance operation element 10 such as a keyboard, detects the performance operation of the performance operation element 10, and performs performance operation information corresponding to the content of the performance operation. 1 to 3), the data processing unit generates performance data based on the performance operation information and sends it to the sound source / effect circuit 7.

  The setting operation detection circuit 5 constitutes a setting operation unit (also referred to as a panel operation unit) together with a setting operation unit (panel operation unit) 11 such as a switch. The setting operation detection circuit 5 detects the setting operation of the setting operation unit 11 and performs setting operation. Setting operation information corresponding to the contents is introduced into the data processing unit, and the data processing unit performs various settings for each unit of the apparatus based on the setting operation information. For example, in the file / folder display selection process, the user uses a setting operator (INC switch or DEC switch) for designating next data or previous data, and changes the current display display to change another file. Information / folder information (referring to information indicating a file / folder) can be instructed to be displayed on the display (12). In addition, file information / folder information corresponding to the current display display can be selected by using a setting operator (OK switch) for selecting a file / folder.

  The display circuit 6 controls display / lighting contents of a display 12 such as an LCD or an indicator / lamp (not shown) such as an LED in accordance with a command from the data processing unit, and performs display assistance regarding performance operation and setting operation. For example, in the file / folder display selection process, file information / folder information in a predetermined format is displayed on the display 12 in accordance with the information display rule controlled by the CPU 1.

  Here, the display 12 is a segment type character display that displays various information necessary for performance and setting as a character string, and has a display performance much lower than that of a matrix type display. In other words, it is basically possible to display only numbers, and in some cases, it is possible to display limited types of alphabets and symbols (A, C,...), But in general, hiragana, katakana, and kanji. Etc. cannot be displayed. In the following example, a 7-segment, 3-digit, 1-line character display with dots is used. However, the present invention is not limited to this, and the number of segments and digits per character may be increased. For example, 14 segments or 16 segments may be used.

  The sound source / effect circuit 7 includes a sound source unit, an audio input unit, an effect circuit unit having a DSP, and the like. The sound source unit generates an audio tone signal based on performance data obtained from performance operation information of the performance operation unit 10-4. Or an audio tone signal based on performance data input from the ROM 3 or the communication I / F 8 can be generated, and the generated audio tone signal is output to the effect circuit unit. The audio input unit outputs an audio tone signal based on audio data input from the ROM 3 or the communication I / F 8 to the effect circuit unit. Then, the effect circuit unit gives a predetermined effect to the audio musical sound signal input from the sound source unit or the audio input unit, and outputs it to the sound system 13. That is, it functions as a performance data reproduction unit together with the sound source unit, and functions as an audio data reproduction unit together with the audio input unit. The sound system 13 is called a musical sound generation unit together with the sound source / effect circuit 7 and includes a D / A conversion unit, an amplifier, a speaker, and the like, and generates a musical sound based on the audio musical sound signal from the sound source / effect circuit 7.

  The communication I / F 8 is a music-only wired I / F such as MIDI, a general-purpose short-distance wired I / F such as USB or IEEE 1394, a general-purpose network I / F such as Ethernet (registered trademark), a wireless LAN, or Bluetooth (registered trademark). It is composed of one or a plurality of general-purpose short-distance wireless I / Fs such as a digital telephone line network, etc., and can exchange various information with external devices. Is connected.

  The storage device ST includes a storage medium such as a semiconductor memory such as a hard disk, an FD (flexible disk), a CD (compact disk), a DVD (digital multipurpose disk), and a flash memory, and a driving device thereof. Many music data such as can be stored. Here, the performance data is music data in an event format such as MIDI, and the audio music data is music data representing a waveform of a musical sound. In the following example, a USB I / F is used as the communication I / F 8, and a USB flash memory is used as the storage device ST.

  Note that not only the electronic musical instrument described above but also an audio device can be applied to the electronic music apparatus. For example, in the case of an audio player, the performance operation unit (10-4) is not necessary, and in the case of an audio data recorder, the performance operation unit (10-4) and the tone generation unit (7-11) are not necessary. .

[Folder information / file information display rules]
In an electronic music apparatus according to an embodiment of the present invention, a large number of music data files such as performance data and audio music data are stored in a storage device (USB flash memory) ST, and are stored separately for each folder. When a desired folder is selected from the storage device ST or a desired music data file is further selected from the selected folder, the name of the folder or file (folder name or file) in the target directory according to a predetermined information display rule. A predetermined character string indicating these folders or files is displayed on the display 12 in a predetermined order as folder information or file information, and a selection switch is displayed when a desired character string is displayed. Is operated, the desired folder or file indicated by the desired character string is selected. FIG. 2 shows information display rules and display examples according to one embodiment of the present invention.

  When a user uses a personal computer (PC) or the like to store and manage a music data file (performance data file) called a song file or music data in the storage device ST, for example, each directory or artist There are cases in which folders are managed separately for each. Also, when purchasing music data from a data download site or purchasing music data at a music data store, music data for several songs are stored in the storage device ST via the PC in a state where they are combined into one folder. can do. The folder information display rule in such a case will be described with reference to FIG.

  In the example of the information display rule shown in FIG. 2A, the storage device ST initially has three folder names FdN = “J pop”, “ Three folders Fd1 to Fd3 to which “anime song 1” and “classic” are assigned are set, and predetermined music data files are stored in the folders Fd1 to Fd3. In this case, when the display of the folder information is instructed by the operation of the setting operator (folder switch) for instructing the folder display, as shown in the second column on the right table (the column “before folder addition”), For example, a predetermined ascending order of the folder names FdN corresponding to the three folders Fd1 to Fd3 [for example, numerical value (number 0 to 9) order> alphabet order> 50 alphabetical order (> indicates the priority of the character type defined in the sort table. )], Three display character strings CS = “001” to “003” starting from “001” are determined as folder information to be displayed. The display 12 first displays a display character string CS = "001" corresponding to the folder Fd1, and the display is sequentially changed to "002" and "003" each time the INC switch is operated. . In addition, the previous display can be restored by operating the DEC switch.

  On the other hand, as shown by the hatched folder graphic on the left side of the same figure, two new music data groups of genre name = “JAZZ” and “animation song 2” are purchased and used in an external device such as a PC. When the folder name FdN newly set in the storage device ST = “JAZZ _ ## 001” and “animation song 2 _ ## 123” is stored in the folders Fda and Fdb and the number of folders Fd becomes five, the display is displayed. The character string CS is as shown in the third column on the right side (the column “After Folder Addition”).

  That is, the newly added folders Fda and Fdb are folder names with a character string: “_ ## ijk” (“i”, “j”, and “k” are arbitrary integers) added to the end of the genre name. FdN is given. Here, the character string “_ ##” in the additional character string is called a “number symbol” or an “ID instruction symbol”. Furthermore, the character string: “ijk” following the number symbol: “_ ##” is called “ID character string”, “ID number”, “ID information”, or simply “ID”, and the genre name in the first half. By using it together, the corresponding folders Fda and Fdb can be specified. The added folders Fda and Fdb are called “folders with ID” or “folders with ID”, and the folder names Fdb corresponding to the folders with IDs Fda and Fdb are called folder names with ID or folder names with ID. . On the other hand, the folders Fd1 to Fd3 existing from the beginning are called “folders without ID”, and the folder names FdN corresponding to the folders without IDs Fd1 to Fd3 are called folder names without ID.

  Regarding the folder information to be displayed, first, it is checked whether or not the ID character string: “ijk” following the number symbol: “_ ##” exists in the folder name FdN, and the third column (“Folder” As shown in the “after addition” column), the display character string CS corresponding to the folder having the folder name for which no ID character string exists, that is, the IDless folders Fd1 to Fd3 set in the storage device ST from the beginning is added to the folder. Although not different from the previous (second column in the right table), for the folders Fda and Fdb having the folder name FdN in which the ID character string exists, the ID character strings: “ijk” = “001” and “123” are displayed as they are. Furthermore, additional information = “.” (Dot) indicating that this character string is an ID character string is displayed together with the end of the ID character string (see * mark). The display mode indicated by * after the folder is added is called “ID display”, and the user can reliably identify that the corresponding folders Fda and Fdb are new data by the ID display. When the display 12 has seven segments with dots, each display character string CS after the folder is added is actually displayed according to the display order indicated by the long arrows as shown in FIG.

  Regarding the display order of the display character string CS, before adding a folder, as described above, the folder names without ID in the second column of the right table of FIG. 2A are sorted by the folder name FdN (sort: data First, the display character string CS = "001" corresponding to the first folder Fd1 is displayed on the display 12, and sequentially corresponds to the second order folder Fd2 in the sort order for each operation of the INC switch. Display character string CS = “002”, and display character string CS = “003” corresponding to the third rank folder Fd3.

  On the other hand, after the folder is added, the display character string CS is sequentially displayed on the display 12 according to the display order of FIG. That is, the folder names with ID are sorted by the first condition, for example, by the ID character string, and the folder names without ID are sorted by the second condition, for example, by the folder name FdN. The display character string CS = "001." Corresponding to the first folder name of the sorted folder name group with ID is displayed on the display 12, and the next-order folder Fdb (in this example, the last-order folder) is operated by the INC switch. “123.” corresponding to is displayed. Next, when the INC switch is operated while the display character string CS = “123.” Corresponding to the last folder name of the folder name group with ID is displayed, the first folder name of the sorted folder name group without ID The display character string CS corresponding to “= 001” is displayed, and “002” and “003” are sequentially displayed in the sort order for each operation of the INC switch as in the case before the folder addition.

  That is, since the folders with IDs Fda and Fdb corresponding to the folder names with ID are more important than the folders without IDs Fd1 to Fd3 corresponding to the folder names without ID, the folder information CS is displayed on the display 12. In order to do this, first, the display character string CS (= “001.”, “123.”) corresponding to the ID-added folders Fda, Fdb is set to the younger one of the ID numbers (“001”, “123”) (“001. ”) In order. Then, display character strings CS (= “001” to “003”) corresponding to the folders without ID Fd1 to Fd3 are displayed from “001” in ascending order of the folder name FdN. Accordingly, the numbers corresponding to the IDless folders Fd1 to Fd3 that existed from the beginning are the same as before the folder addition.

  For reference, an example of a display character string after adding a folder by a conventional display method is shown in the rightmost column of the right table of FIG. In the conventional display method, after adding a folder, as in the case before adding a folder in the first column of the right table, all folder names are sorted by the folder name FdN, and the display character strings are sequentially determined from “001” in the sort order. The display order is sequentially displayed as “002”, “003”,... Therefore, according to the conventional display method, since the newly added folders Fda and Fdb, “004” and “005” are not displayed, and what number should be selected to select newly purchased data. There are problems such as not knowing and changing the number of data that has been heretofore.

  Although the display rule for folder information has been described with reference to FIG. 2, the same display rule can be applied to file information. For example, when music data file information stored in a selected folder Fd is displayed and desired file information is selected, processing is performed as follows: a plurality of music data under the folder Fd The file name (FiN) of the file (Fi) is acquired, and the file name with ID including the ID character string is sorted according to the first condition (for example, ID character string), and the file name without ID that does not include the ID character string Are sorted by the second condition (for example, file name FiN). Next, corresponding to the files with ID sorted under the first condition (for example, ID character string), the ID character strings are displayed on the character display in the sort order, and the ID character string is a specific file. An additional display (for example, with a dot) informs that the ID is indicated. Then, in correspondence with the file names without ID sorted by the second condition (for example, file name FiN), the numbers are displayed in numerical order from “001”. Regarding the directory of music data files, not only when a plurality of music data files are stored under the folder as described above, but also when a plurality of music data files are stored in the storage device ST without setting a folder. The file information display rule as described above is applied in the same manner. Note that the term “/” used in the following description means “or” in principle, and the terms before and after “/” correspond in the same order.

  As described above, in the electronic music apparatus according to one embodiment of the present invention, a plurality of music data files are stored under a plurality of folders set in the file storage means ST. In the folder display selection process / file display selection process, first, the folder name FdN / file name (FiN) corresponding to the folder Fd / file (Fi) is acquired, and the acquired folder name FdN / file name is an ID character string. To see if it contains. Next, the folder name with ID / file name with ID including the ID string is sorted in a predetermined order according to the first condition (for example, ID string), and the folder name without ID / ID without ID string The file names are sorted in a predetermined order according to the second condition (for example, folder name FdN / file name), and the character string CS indicating the folder Fd / file is sequentially displayed on the segment type character display 12 in the sorted order. . At this time, an ID character string is displayed corresponding to the folder name with ID / file name with ID, and the ID character string is an ID (identification information) indicating a specific folder with ID / file with ID. Announcements with additional indications (eg with dots). A number indicating the sort order is displayed corresponding to the folder name without ID / file name without ID. Then, when a selection operation is performed when a desired character string CS is displayed, a corresponding file / folder is selected.

[Example of operation flow in file / folder display selection processing]
FIG. 3 is a flowchart showing an operation example of the display order determination process in the file / folder display selection process according to one embodiment of the present invention, and “file (folder)” in FIG. 3 agrees with “file / folder”. is there. In the following description, it is expressed as “file / folder” or the like for convenience, but this processing flow is applied to each of the folder and the file. However, when a file and a folder are mixed in the same directory, this processing flow may be applied to each of the folder and the file, or the file and the folder may be handled equally.

  In FIG. 3, when the electronic music apparatus is operating in the file / folder display selection mode, display of file information / folder information is instructed by a user operation of a predetermined setting operator (file switch / folder switch). The CPU 1 starts this file / folder display order determination process. First, in step P1, a directory for displaying file information / folder information in the storage device ST is designated, and the process proceeds to step P2.

  In step P2, a list of file names (FiN) / folder names FdN included in the specified directory is acquired, read into the current buffer on the RAM 2, and the first file name information (FiN) / folder name information FdN in the list. The ID character string (number symbol: “_ ##” followed by character string: “ijk”) is checked. That is, it is checked whether an ID character string is included in the file name / folder name to be processed. In the next step P4, it is determined whether there is an ID character string in the file name / folder name as a result of the check. If there is an ID character string (P4 = YES), the process proceeds to step P5, where Add a flag “ID present” to the name / folder name.

  When it is determined that there is no ID character string (P4 = NO) or after the “with ID” flag addition processing in step P4, the process proceeds to step P6, and whether or not the current check target is the last file name / folder name Determine whether. If it is not the last file name / folder name (P6 = NO), the process returns to step P3, and the processes of steps P3 to P6 are repeated for the next file name information / folder name information. When the processes of Steps P3 to P5 are completed for the last file name information / folder name information (P6 = YES), the process proceeds to Step P7. That is, first, all file names / folder names are scanned and an “ID present” flag is added to those having an ID character string, thereby classifying them into “with ID” and “without ID”.

  In step P7, the file name / folder name with the “ID present” flag added is sorted by ID character string, and in the next step P8, it is determined whether there is a file name / folder name having the same ID character string. To do. Here, it is determined whether there is a file name / folder name having the same ID character string. If there is a file name / folder name having the same ID character string (P8 = YES), the process proceeds to Step P9. Sort file names / folder names having the same ID character string by file name / folder name. That is, in Steps P7 to P9, the file names / folder names with “ID” are sorted in the order of the ID character string (P7). Sort by (P9).

  When it is determined that there is no file name / folder name having the same ID character string (P8 = NO) or after the file name / folder name sorting process in step P9, the process proceeds to step P10 and the “ID present” flag is set. Sort missing file / folder names by file / folder name. That is, the file name without ID / folder name without ID is sorted by file name / folder name. Note that the inside of the electronic music apparatus (for example, the ROM 3) has a sort table that defines the sort priority order of character types, and the sort processing in steps P7 to P10 is performed by referring to this table.

  After the sort processing of the file name / folder name without the “ID” flag in step P10, the process proceeds to step P11, and the file list / folder list in which the file names / folder names sorted in steps P7 to P10 are arranged in the sort order is a file. This is set for calling information / folder information, and the file information / folder information at the head of this list, that is, the display character string CS is displayed on the display 12. Then, the display order determination process ends.

  By a series of steps P7 to P11, a file list / folder list in which file names / folder names are arranged in the order of “with ID” → “without ID” is created in the electronic music apparatus, that is, on the RAM 2. . FIG. 4 shows an example of a file list according to an embodiment of the present invention. In this file list, as shown in the frame of FIG. 4, the file name FiN and the display character string CS are described according to the sort order in each group in the order of the file name group with ID → the file name group without ID. . In order to facilitate understanding, the left and right sides of the frame show the file names FiN of the file list and the file Fi corresponding to the display character string CS and the type of the file or file name. The reference symbols = “Fia”, “Fib”,... Of the sorted file names FiN = “AA ... A _ ## aaa”, “BB ... B _ ## bbb”,. Show.

  Regarding the display of the file information, as described above, first, the file information at the head of the list, that is, the display character string CS = “aaa.” Is displayed on the display 12 by setting the file list. Here, when the INC switch is operated, the next file display process (FIGS. 5 to 6) instructs the next file display, and the display character string CS = “bbb.” Of the next order is called for display. And displayed on the display 12. Each time the INC switch is operated, the display character string CS is displayed in the ascending order of the list. On the other hand, when the DEC switch is operated, the display character string CS is displayed in the descending order of the list by the previous file display process (not shown). If the OK switch is operated, the file Fi corresponding to the display character string CS displayed on the display 12 at that time is selected and read from the recording device ST.

  The folder list is configured in the same manner as the file list (see FIG. 4), and the folder information is displayed by the next folder display process and the previous folder display process (both not shown). This is done in a similar manner.

  5 and 6 are flowcharts showing an example of the operation of the next file display process according to one embodiment of the present invention. The next file display process is started by operating the INC switch, that is, the next file instruction operation in step S1, and the CPU 1 performs the processes of steps S2 to S16. That is, for the file information CS currently displayed on the screen of the display 12, it is first determined in step S2 whether or not it corresponds to a file name with ID, and if it is a file name with ID (S2 = YES), further steps are performed. In S3, it is determined whether or not the file name with the last ID is supported. If the file name with the last ID does not correspond (S3 = NO), the display character string information CS corresponding to the file name with the next rank ID is called from the file list (S4), and the display character string CS is displayed. Is displayed on the display screen [ID display] (S5), and the next file display process is terminated.

  If it is determined in step S3 that it corresponds to the file name with the last ID (S3 = YES), the file name without ID is checked in the file list in step S6 (FIG. 6), and the file name without ID is checked in step S7. Determine if it exists. If the file name without ID exists (S7 = YES), the display character string information CS corresponding to the file name without ID at the head of the group without ID is called from the file list (S8), and the display character string CS is displayed. Is displayed on the display screen (S9), and the next file display process is terminated.

  If it is determined in step S2 (FIG. 5) that the current display corresponds to a file name without ID (S2 = NO), whether or not it corresponds to the last file name without ID in step S10 (FIG. 6). Determine. If the file name does not correspond to the last file name without ID (S10 = NO), the display character string information CS corresponding to the next file name without ID is called from the file list (S11), and the display character string CS is displayed. Is displayed on the display screen (S12), and the next file display process is terminated.

  If it is determined in step S10 that the current display corresponds to the last file name without ID (S10 = YES), the presence or absence of the file name with ID is checked based on the presence or absence of the “with ID” flag in the file list (S13). In step S14, it is determined whether a file name with ID exists. If it is determined in step S14 that a file name with ID exists in the file list (S14 = YES), or if it is determined in step S7 that a file name without ID exists in the file list (S7 = NO), the display character string information CS corresponding to the file name with the head ID is called from the file list (S15), and the head ID string and the dot indicated by the display character string CS are displayed on the display screen [ ID display] (S16), the next file display process is terminated.

  If it is determined in step S14 that the file name with ID does not exist in the file list (S14 = NO), the file is the same as in the case where it is determined in step S7 that the file name without ID exists (S7 = YES). The display character string information CS corresponding to the file name without ID at the head of the group without ID is called from the list (S8), the number: “001” is displayed on the display screen (S9), and the next file display process is terminated. .
