The display screen can be shifted by the above, and if there is a search instruction operation (SR) on either of the music content use screens A and B, (1) the music content search screen C is shifted to. On the search screen C, a search result (LS) of music content searched according to the search condition (RC) from among a large number of music contents SD: SD1, SD2,... Stored in the music content storage devices 4a, 4b is displayed. When the desired music content SD is further selected from the search result (LS) and the determination instruction operation (DB) is performed, the search result is retained (saved) as the search condition information (RC) and the search result (LS). (2) After being held (saved) in the means 2a, (2) moving to the original music content use screens A and B, and using the predetermined music content selected on the search screen C on the original use screens A and B Can do. Further, when a search instruction operation (SR) is performed on the use screens A and B and (3) the screen is moved again to the music content search screen C, the search condition (RC) is based on the search result information held in the search result holding means 2a. ) And the search result (LS) are reproduced on the music content search screen C, and the search result title display (TL) notifies that the search result is the previous search result. Further, when a new search condition (RC) is input (designated) in a state where the search result (LS) is displayed on the music content search screen C, the fact that the previous search result is indicated is also notified. I will explain in detail below.

[Various display examples of the search screen]
In the music content utilization system according to one embodiment of the present invention, when the music content utilization screens A and B are shifted to the music content retrieval screen C, or when the music content is retrieved according to the retrieval condition specified on the music content retrieval screen C. When the search condition is changed after the music content search, the display of the search result (LS) or the like on the music content search screen C is controlled based on the previous search history, and the search result (LS) title display ( By changing (TL), the convenience of searching for music contents is enhanced. 6 to 8 show various display examples of the search screen in the music content utilization system according to one embodiment of the present invention.

(1) Initial screen Ca: When the search screen C is moved for the first time, or when, for example, the drive 4b is removed after searching the music content for the removable drive 4b, the search result is returned for some reason (error). When the screen shifts to the search screen C after being invalidated, the initial screen Ca shown in FIG. 6 is displayed on the display 13 as the search screen C. In the lower part of the search screen C, the search, audition and decision buttons RB, TB, and DB described above are operably displayed, a search condition input display area RC is provided on the left side, and a search result list is displayed on the upper right side. A display area LS is provided, and a detailed data display area DT is provided at the lower right side.

  In the search condition input display area RC, the search location RC1 where the music content to be extracted by the search is recorded, the predetermined keyword RC2 representing the characteristics of the music content to be extracted, the time signature RC3 of the music content to be extracted, and the tempo RC4 of the music content to be extracted. The search condition can be set (designated) by inputting an arbitrary item among the search items such as the combination type of the music content material DE related to the music content to be extracted, that is, the data type RC5 of the music content to be searched. . In this case, for the search items RC1 to RC4, conditions can be specified by inputting in the search item input field, and for the search item RC5, by inputting a check in a desired search item input field (combination type check field), “Registration song” (automatic performance data + registration data), “registration” (registration data only) and / or “song” (automatic performance data only) can be designated.

  When a search process (search button process) is performed by operating the search button RB, the name and combination type of the music content that matches the search condition are displayed in the search result list display area LS. A predetermined display is made in the search result title (title) display field TL provided at the top. Further, when a predetermined music content is selected from the search result list LS, detailed data regarding the selected music content is displayed in the detailed data display area DT. However, in the initial screen Ca, there is no display of variable information in each of the display areas RC: RC1 to RC5, LS, and DT, and the search result title display field TL is also blank as shown by a broken line.

(2) First screen Cb: After a search process is performed by inputting a search item and pressing the search button RB, the first screen Cb shown in FIG. That is, for the input search condition RC: “search location RC1 = built-in drive, keyword RC2 = piano, data type RC5 =“ song with registration ”and“ registration ””, the search result title display field TL indicates “this search. "Result" is displayed, and the results of executing the search process according to the input search conditions are displayed in a list in the search result list display area LS.

  Further, the displayed search result list LS is moved to the desired line position by moving the cursor placed at the top line position of the list immediately after the search process (search button process) to the desired line position. The displayed song data (music content) can be selected, and the detailed data of the selected song data is displayed in the detailed data display area DT. Further, when the audition button TB is operated, the selected song data can be in a trial listening state in which the selected song data is developed (reproduced / set) on the electronic music apparatus on a trial basis. After a predetermined set time (for example, several minutes to several hours), the trial listening state is terminated and the original state is restored. For example, when the selected song data includes “type RC5 =“ song ”or“ song with registration ”, that is, automatic performance data, the automatic performance data is reproduced (musical tone generation) by the sound source / effect circuit 8 on a trial basis. If the selected song data includes “type RC5 =“ registration ”or“ song with registration ””, that is, registration data, registration is set in the sound source / effect circuit 8 on a trial basis. To develop.

  In the first screen Cb of FIG. 7A, as shown by hatching at the fourth line position of the list LS, the song of the fourth line type = “Regist” is further extracted from the plurality of song data retrieved by the retrieval process. The fact that data = “jazz piano” has been selected is highlighted, and its detailed data is displayed in the detailed data display area DT. Here, when the trial listening button TB is operated, registration based on this song data is provisionally set in the sound source / effect circuit 8, and a musical tone signal based on the actual performance of the performance operator 11 is experimentally tested in the provisional setting state. It can be generated.

(3) Second screen Cc: After searching on the search screen C, when the search screen C is temporarily exited to move to the music content use screens A and B and then transferred to the search screen C again, it is shown in FIG. The second screen Cc to be displayed is displayed as the search screen C. That is, for example, when the search is performed from the song recording / playback screen A to the search screen C and the first screen Cb of FIG. 7A is displayed, the determination button DB is operated to operate the song recording / playback screen A. , The search items input as the search conditions RC1 to RC5, the contents of the search result list LS, the detailed data of the song data (music content) in the list LS, and the information of the song data selected from the list LS Is not cleared and is stored in the search result storage area 2a of the RAM 2 as search result information. Therefore, when the screen is moved again to the search screen C, the search condition input is performed according to the search result stored in the search result storage area 2a. In the display area RC, the search result list, and the detailed data display areas LS and DT, information having the same contents as the search screen 2Cb is reproduced and the search result type is displayed. For Le display column TL, it is displayed as "Last Result" by a transition again to search screen C.

  In this way, when the screen is moved again to the search screen C, “previous display result” is displayed to notify the user that the search result list displayed on the search screen C = Cc is the previous search result ( Notification). Displaying at the time of re-transition to the search screen C without clearing the previous search result can effectively use the previous search result again and select new contents from the list of search results. There is great significance in terms of convenience.

(4) Third screen Cd: When the search condition is changed while the search result is displayed, the third screen Cd shown in FIG. For example, when the search is performed by moving from the song recording / playback screen A to the search screen C and the first screen Cb of FIG. 7A is displayed, the keyword is changed from “piano” to “guitar” as a search condition. When changed, the display content of the search result title display field TL displayed as “current search result” is changed to “previous display result”. Thereby, it is possible to notify (notify) the user that the contents of the search result list LS on the right side are not based on the search conditions currently set in the search condition input display area RC on the left side. In addition, since the change of the search condition cancels the state where the specific song data is selected, the highlighted display of the search result list LS and the data display in the detailed data display area DT disappear, and a new search stage is entered. Make users strongly recognize that they have entered.

[Example of processing in the search window]
9 to 11 are flowcharts showing processing examples on the search screen in the music content use system according to the embodiment of the present invention. The search screen processing in FIG. 9 is started by the processing in the search screen transition processing step (A5, B5) in the music content use screen processing, that is, the song recording / playback screen processing (FIG. 4) or the song editing tool screen processing (FIG. 5). . When the search screen process starts, the CPU 1 first examines the search result storage area 2a in the RAM 2, and determines whether or not previous search result information is stored in the search result storage area 2a in step C1. Here, when the search screen transition process is first performed after the operation of the music content use process, or the media 4b that is the search place (target) in the search process performed immediately before is inserted and removed, and the search result is cleared. When it is determined that there is no previous search result (C1 = NO) as in the case, the process proceeds to step C2, and any variable information is displayed in each display area RC: RC1 to RC5, LS, DT as shown in FIG. An initial search screen Ca that does not exist is displayed on the display 13, and the display of the name display column TL of the search result list LS is made blank.

  On the other hand, when it is determined in step C1 that there is a previous search result as in the case where the search is performed on the search screen C and then the music content use screens A and B are returned to the search screen C again (C1 = YES), the process proceeds to step C3, and the second search screen Cc as shown in FIG. That is, based on the search result information stored in the search result storage area 2a, the previous search result is reproduced in each of the display areas RC: RC1 to RC5, LS, DT, and the name display field TL of the search result list LS. Is the “previous search result”.

  After the search screen transition initial display process in step C2 or C3, various processes corresponding to various user operations are performed in step C4. 10 and 11 show examples of processing executed in step C4.

  The search condition setting process in FIG. 10 (1) starts when a search item is input to the search condition input display area RC: RC1 to RC5 by a user operation. First, in step D1, the input search place RC1 is entered. One or more search items among the keyword RC2, the time signature RC3, the tempo RC4, and the data type RC5 are set as the search condition RC. Next, when “current search result” is displayed in the name display field TL of the search result list LS on the search screen C in step D2, this display is changed to “previous search result” and the search condition is set. The process ends, and if not, the search condition setting process ends immediately. Then, the process returns to the “process according to the operation” (FIG. 9: C4) of the search screen process.

The search button process in FIG. 10 (2) starts when the user operates the search button RB on the search screen C. In the first step E1, the search condition setting process (FIG. 9: C1) sets the search condition RC. Song data (music content) SD including a music content material DE having a combination that matches the set search target data type (combination type) RC5 is extracted from the music content storage devices 4a and 4b. In this case, the extraction of the music content material of the combination that matches the search target data type RC is
(A) A method of referring to the description in the management data file MF included in each folder (second layer) Fa, Fb,... (See FIG. 2), or
(B) Any one of the methods for checking the existence of music content materials DE: DE1a, DE1b,... Included in each song folder (third layer), that is, song data (music content) SD: SD1, SD2,. By the method.

  In the next step E2, song data matching the other search conditions RC1 to RC4 set as the search condition RC in the search condition setting process (FIG. 9: C1) is further selected from the song data extracted in step E1. Extract. Then, in step E3, the song data extracted in step E2 is displayed as a search result in the search result list display area LS, and the name TL of the search result list LS is set as “current search result”.

  Next, in step E4, predetermined song data is automatically selected according to a predetermined rule, for example, the first song data in the search result list LS is selected. Then, the selected song data portion in the search result list LS is highlighted. Further, at step E5, the details of the selected song data are displayed in the detailed data display area DT, the search button process is terminated, and the process returns to the “process according to operation” (FIG. 9: C4) of the search screen process. .

  The song selection process in FIG. 11 (1) is started by the user's cursor operation in the search result list display area LS on the search screen C. In the first step F1, the desired song data is retrieved from the search result list LS based on the user operation. Select. For example, when the cursor is moved to the desired song data position and clicked, the song data at that position is selected. Then, in step F2, the details of the selected desired song data are displayed in the detailed data display area DT, the song selection processing is terminated, and the search screen processing “processing according to operation” (FIG. 9: C4) is performed. Return.

  The trial button processing in FIG. 11 (2) is started by the user operating the trial button TB on the search screen C. In the first step G1, the currently selected song data is developed on the electronic music device on a trial basis. To do. For example, if the material data DE of the song data (music content) SD is automatic performance data, the automatic performance data is reproduced (musical sound generation) by the sound source / effect circuit 8 and the material data DE of the song data (music content) SD. Is the registration data, the tone signal generator parameter is set in the sound source / effect circuit 8 in accordance with the registration data. Then, after the trial listening button TB is operated again or a predetermined time (for example, several minutes to several hours) elapses and the trial listening state is finished, the development of the selected song data is canceled in step G2. . For example, the reproduction of the automatic performance data is stopped, and the registration data is restored to the original setting state. Then, the audition button process is terminated, and the process returns to the “process according to the operation” (FIG. 9: C4) of the search screen process.

  The decision button process in FIG. 11 (3) is started by the user operating the decision button DB on the search screen C. In the first step H1, the current search conditions RC: RC1 to RC5, search result list LS and song data selection are selected. The state (DT) is stored in the search result storage area 2a as search result information. In this case, when previous search result information is stored in the search result storage area 2a, it is updated (overwritten) with new search result information.

  In the next step H2, the currently selected song data is determined as the song data to be subjected to the music content use processing, and the music content use screen processing, that is, the song recording / playback screen processing (FIG. 4) or the song editing tool screen processing. Processing to return to the previous screen determined in the previous screen determination step (A4, B4) of (FIG. 5) is performed, and this determination button processing and search screen processing (FIG. 9) are terminated.
