  FIG. 2 is a schematic diagram showing an example of the score display screen 24 (24a and 24b) according to the present embodiment. For convenience of explanation, the box is simply indicated by a box. However, in each section (bar) box, it is assumed that a staff score, musical note data, and the like are displayed. A hatched box indicates a specified section.

  FIG. 2A is a diagram showing an example of a score display screen 24a that displays an entire song based on song data. In the state shown in the figure, data for the second measure, data for the sixth measure, and data for the seventh measure are designated. The 6th bar and 7th bar data are continuous in time, but these data and the 2nd bar data are discontinuous in time.

  Further, as shown in the figure, the designated section (bar) is displayed in a display mode different from other sections (bars). Here, the different display modes include, for example, the background color of the designated section different from the background color of the other section, or one or both of the staff score and notes of the designated section are different from those of the other sections. It is to display with the thickness etc. In addition to this, the specification section and the other sections are referred to as displaying in different display modes so that the specified section and other sections can be visually distinguished and recognized. In this example, the reproduction start position is the head of the second measure indicated by the reproduction start position instruction RP.

  The music data in this embodiment is, for example, MIDI format automatic performance data. In this embodiment, in addition to generating the score display screen based on the automatic performance data in the MIDI format, data for displaying the score included in the song data separately from the automatic performance data for reproduction, or for reproduction The score display screen may be generated using score display data in a separate file from the song data. Furthermore, only the music score display data may be recorded, and automatic performance data may be generated from the music score display data during reproduction.

  FIG. 2B is a diagram showing an example of the score display screen 24b when only the designated section is displayed. The page switching tab 25 arranged on the left side in the figure can be switched to a desired page by selecting (for example, clicking after pointing) with an operator such as a mouse.

  As shown in the figure, on the score display screen 24b, only the designated section (2nd bar data, 6th bar data, 7th bar data) is displayed so as to be continuous in time. That is, the time intervals between the data of the second measure and the data of the sixth measure are displayed close together.

  By displaying only the designated section in a time-sequential manner in this way, it is possible to create a score only for the designated section. Therefore, the user can perform performance practice by looking at the score of only the necessary section.

  In this example, each of the score display screen 24a and the score display screen 24b is alternatively selected and displayed as a page, but these screens may be simultaneously displayed in parallel in the same window. Then, the score display screen 24b may be displayed in a separate window as a new display screen.

  FIG. 3 is a diagram illustrating an example of the section designation screen 34. The section designation screen 34 is displayed as a separate window in response to a section designation instruction from the user.

  The section designation screen 34 includes, for example, a configuration list CL, a selection switch SS for selecting whether or not a section is designated, a confirmation switch OK, and a cancel switch CN.

  A plurality of configurations can be displayed as a list in the configuration list CL. In each configuration, a configuration name and section information are recorded. The configuration name can be arbitrarily assigned by the user. The section information is information for identifying the designated section, and is recorded together with the configuration name when the user creates the section designation configuration.

  In the figure, the configuration indicated by the oblique lines is selected. In this example, configuration 2 is selected. Configuration 2 is a configuration in which data for the second measure, data for the sixth measure, and data for the seventh measure are designated, and the score display screen 24 based on this configuration is as shown in FIG.

  The selection switch SS for selecting presence / absence of section designation has two switches of “configuration to be reflected in the score” and “no section designation”, and the configuration currently selected under “configuration to be reflected in the score”. Are displayed in the configuration name box 35, and section information (information indicating the specified section) associated with the configuration name is displayed in the section information box 36. In addition, when the composition is reflected in the score, the “configuration to be reflected in the score” switch is selected with an operator such as a mouse. If no section is specified, select the switch without section specification.

  When creating or changing a configuration on the section designation screen 34, a new configuration name is input in the configuration name box 35, and a section (measure) to be specified in the section information box 36 is input by a number. Similarly, the configuration can be changed using the configuration name box 35 and the section information box 36. The section can be designated not only by the section designation screen 34 but also by selecting the section to be designated on the score display screen 24a with an operator such as a mouse.

  When the operation here is completed, the set content is reflected on the score display screen 24 and the like by operating the confirmation switch OK. When the cancel switch CN is operated, the setting change here is discarded, and the score display screen 24 is displayed based on the previous setting.

  The section designation screen 34 is not limited to the one shown in FIG. 3, and can display a plurality of configurations and section information of the plurality of configurations. The section information can be newly input and changed, and the configuration can be changed. Anything can be used as long as it can be selected.

  In addition, each of the plurality of components here may correspond to each page of the score display screen 24. In this case, for example, configurations 1 to 4 correspond to pages 1 to 4 of the score display screen 24.

  As described above, the configuration of the designated section may be recorded in advance for each piece of music data in addition to the one created by the user as described above so that the user can select it.

  FIG. 4 is a flowchart showing the automatic performance process according to the embodiment of the present invention.

  In step SA1, automatic performance processing is started. In step SA2, for example, music data to be processed is selected and read from a plurality of music data stored in the external storage device 15 in FIG.

  In step SA3, the entire music corresponding to the music data read in step SA2 is displayed on the display 14 of FIG. 1 in the same display manner. Here, displaying the score as a whole means a state where the score of the entire song can be displayed by scrolling or the like without necessarily displaying the entire song on one screen.

  In step SA4, various settings are performed. The settings performed here include, for example, whether or not a section is specified, a display mode in the case of specifying a section (displaying only the specified section / displaying the entire display), setting a playback start position, and whether or not repeated playback is performed.

  In step SA5, it is detected whether or not a reproduction start position instruction operation has been performed. If there is an operation for designating the reproduction start position, the process proceeds to step SA6 indicated by an arrow of YES, and the reproduction start position is updated (moved). Note that the display position of the reproduction start position instruction RP in FIG. 2 is also updated along with the update of the reproduction start position. If there is no instruction, the process proceeds to step SA7 indicated by a NO arrow.

  In step SA7, it is detected whether or not a section is designated. When the section is designated, the process proceeds to step SA8 indicated by a YES arrow. If no section is designated, the process proceeds to step SA16 indicated by a NO arrow.

  In step SA8, for example, the section designation screen 34 of FIG. 3 is opened, and the configuration of the designated section is selected from the configuration list, or a new configuration is created and section information is acquired.

  In step SA9, it is determined whether or not the setting is to display only the designated section. When displaying only the designated section, the process proceeds to step SA10 indicated by a YES arrow. When a section other than the designated section is also displayed (the whole is displayed), the process proceeds to step SA11 indicated by a NO arrow.

  In step SA10, a new score screen (for example, the score display screen 24b in FIG. 2B) is created, and the specified sections included in the section information acquired in step SA8 are displayed in a time-series order. Thereafter, the process proceeds to step SA12.

  In step SA11, the score of the entire song is displayed by changing the display mode of the designated section included in the section information acquired in step SA8 from the other sections (for example, the score display screen 24a in FIG. 2A).

  In step SA12, it is determined whether or not the reproduction start position is included in any of the designated sections. If it is within the designated section, the process proceeds to step SA16 indicated by an arrow of YES. If it is not within the specified section, the process proceeds to step SA13 indicated by a NO arrow.

  In step SA13, it is determined whether or not any of the designated sections included in the section information acquired in step SA8 is behind the playback start position. If there is a designated section, the process proceeds to step SA14 indicated by a YES arrow. If there is no designated section, the process proceeds to step SA15 indicated by a NO arrow.

  In step SA14, the reproduction start position is changed to the head of the designated section immediately after the reproduction start position. Thereafter, the process proceeds to Step SA16.

  In step SA15, the playback start position is changed to the head position of the head section of all the specified sections included in the section information acquired in step SA8.

  In step SA16, the reproduction process shown in FIG. 5 is performed. In the reproduction process, when there is a section designation, only the designated section is reproduced, and when there is no section designation, the entire music is reproduced. After the reproduction ends, the process proceeds to step SA17.

  In step SA17, an end operation of this process is detected. If an end operation is detected, the process proceeds to step SA18 indicated by a YES arrow, and the automatic performance process ends. If the end operation is not detected, the process returns to step SA2 indicated by the NO arrow and the subsequent processing is repeated.

  FIG. 5 is a flowchart showing the reproduction process performed in step SA16 of FIG.

  In step SB1, the reproduction process is started, and in step SB2, it is determined whether or not the section designation is set. If there is a section designation (section information is acquired in step SA8 in FIG. 4), the process proceeds to step SB3 indicated by an arrow of YES. If no section is specified (no section information is acquired in step SA8 in FIG. 4), or no section is specified in step SA7, the process proceeds to step SB6 indicated by a NO arrow.

  In step SB3, it is determined whether or not the setting for repeated playback is ON. If the repeat playback setting is ON, the process proceeds to step SB4 indicated by the YES arrow. If the repeat playback setting is OFF, the process proceeds to Step SB5 indicated by a NO arrow.

  In step SB4, the designated sections included in the section information acquired in step SA8 in FIG. 4 are reproduced in chronological order from the reproduction start position, all designated sections after the reproduction start position are reproduced, and then set to the head position of all designated sections. Return playback continues. Thereafter, the process proceeds to Step SB9.

  In step SB5, the designated sections included in the section information acquired in step SA8 in FIG. 4 are reproduced in chronological order from the reproduction start position. Thereafter, the process proceeds to Step SB9.

  In step SB6, it is determined whether or not the setting for repeated playback is ON. If the repeat playback setting is ON, the process proceeds to step SB8 indicated by a YES arrow. If the repeat playback setting is OFF, the process proceeds to step SB7 indicated by a NO arrow.

  In step SB7, all sections are reproduced in chronological order from the reproduction start position. Thereafter, the process proceeds to Step SB9.

  In step SB8, all sections are reproduced in chronological order from the reproduction start position, all the sections after the reproduction start position are reproduced, and then the playback is returned to the start position of all the sections. Thereafter, the process proceeds to Step SB9.

  In step SB9, it is determined whether or not reproduction has ended or whether or not there has been an instruction to end reproduction. When the reproduction is ended, the process proceeds to step SB10 indicated by an arrow of YES, and the reproduction process is terminated, and the process proceeds to step SA17 in FIG. If the reproduction is not terminated, the process returns to step SB2 indicated by the NO arrow and the subsequent processing is repeated.

  As described above, according to the embodiment of the present invention, it is possible to clearly display a plurality of designated non-consecutive sections in a display mode distinguished from other sections. Also, it is possible to continuously reproduce only the designated section. Furthermore, only the designated section can be displayed as a series of musical scores.

  In this way, for example, when the user refers to the score display and wants to concentrate and practice only a part of the music, a practice score suitable for the user can be prepared. Moreover, by preparing a plurality of sets of sections, it is possible to prepare a musical score for practice according to the situation.

  In the embodiment, the playback start position can be freely set by the user with an operator or the like. However, the playback start position may be controlled so that it cannot be set outside the designated section. Further, when the playback start position is moved in a section other than the designated section, for example, the playback start position may be immediately moved to a position in the designated section closest to the position or the start position of all designated sections.

  In the embodiment, the section is specified in units of bars. However, the present invention is not limited to this. For example, sections can be specified in units of beats, notes, phrases, multiple bars (2 to 8 bars, etc.), and the like. May be.

  Also, by connecting a printing device such as a printer to the automatic performance device of this embodiment, it is possible to print a score corresponding to the score display screen 24 generated in this embodiment.

  Note that this embodiment may be implemented by a general-purpose computer or the like in which a computer program or the like corresponding to this embodiment is installed.

  In that case, the computer program or the like corresponding to the present embodiment may be provided to the user while being stored in a storage medium that can be read by the computer, such as a CD-ROM or a floppy disk.
