[Prior art]
2. Description of the Related Art Conventionally, a device or a program for displaying a musical score based on automatic performance data is known (for example, JP-A-11-327427). In these devices, for example, a score is displayed on a display composed of a liquid crystal display panel (LCD), a CRT, or the like. In general, the automatic performance data has a format in which data for designating the pitch of a musical tone is included together with timing data of a sounding or muting event. Timing data is information representing the time at which an event occurs, the time interval between events, and the like. When a musical score is displayed based on such automatic performance data, the automatic performance data is analyzed, and the types of notes and rests are determined according to the duration of sound generation and the time interval of sound generation timing. Further, as the display position for displaying the note on the score, the display position in the vertical direction is determined according to the pitch, and the display position in the horizontal direction is determined according to the note length, thereby displaying the note, rest, various music symbols, and the like.

[Problems to be solved by the invention]
By the way, in general score display, the display of a note may be omitted as a score display method. In particular, when displaying a musical symbol of a type that connects notes and notes, for example, when displaying a performance symbol representing glissando, there are cases where a note at the time of glissando end (or glissando start) is displayed and not displayed. is there. That is, depending on the user, in order to express a characteristic musical expression, there are cases where it is desired to separately display the case where the note at the end of the glissando (or the start of glissando) is not displayed. However, in the conventional apparatus as described above, automatic performance data is analyzed and a note is displayed based on the result. In other words, since the automatic performance data display method is determined by a predetermined analysis method in the apparatus, musical notes are always displayed in the same display method uniquely throughout the entire score. As described above, in the conventional apparatus for displaying the score according to the automatic performance data, it is very inconvenient because the score display reflecting the note display in the method intended by the user cannot be performed at an appropriate position. There was a problem.
[0004]
The present invention has been made in view of the above-described points. The musical score display data has attribute information that designates whether to display each musical note symbol on the score or not, and according to the score display data. It is intended to provide a storage medium storing score display data that can display a score reflecting a user's intention by displaying a score, a score display device using the score display data, and a program. is there.

[0015]
Here, the data structure of the score display data will be described. FIG. 2 is a conceptual diagram showing an example of the data structure of the score display data.
The score display data defines the position (display position) where various events such as notes and music symbols to be displayed on the staff displayed on the display 6A are arranged, and the type of various events displayed at the display position. It is data to be. One musical score display data includes a plurality of event data composed of a sequence of timing data and musical score symbol data. The timing data defines the display position in the horizontal direction (X direction) on the display 6A where the musical score data should exist, and is described in the same format as the timing data of automatic performance data. For example, the unit is a predetermined number of notes (eg, 960 notes), such as relative timing from the previous event in time, absolute timing from the beginning of a song or the beginning of each measure, etc. In many cases, it is represented by a clock (also referred to as a tick) divided into 480 or the like. In this embodiment, as shown in FIGS. 4 to 6 to be described later, the timing data is set to “1: 1: 000”, “2: 3: 240”, etc., and “measure number: beat number: clock” in order from the front. ". In other words, “1: 1: 000” is timing data indicating the display position in the X direction represented by 0 (000) clock of the first beat of the first measure, and “2: 3: 240” is the second measure. Timing data indicating the display position in the X direction represented by 240 clocks of the third beat.
[0016]
The musical score data includes at least one of a normal event, a sub-event, and an attribute event. In this embodiment, the normal event is data for displaying a time signature, a key signature, a tempo mark, a clef, a note head, a note tail, a rest, a bar line, text, and the like on a score. Sub-event is data for modifying the normal event just before, for example, staccato or tenuto performance symbols related to the note event, dotted marks related to the note head event, symbols such as tie, glissando, portamento, etc. are displayed on the score. It is data to do. The attribute event modifies the immediately preceding normal event or sub-event, and includes, for example, a parameter that specifies “display / not display” the normal event or sub-event itself. Of course, the attribute event may include other parameters such as a horizontal offset value, a vertical offset value, and parameter values related to the display position of the normal event or sub-event. The above sub-events and attribute events have the same timing data as the regular events and sub-events to be modified. This clarifies the event to be modified. A plurality of sub-events and attribute events can be described for one normal event. A plurality of attribute events can be described for one sub-event.
[0017]
Each event data as described above is described by a text meta event in a standard MIDI file (SMF), for example, and predetermined “event information (for example, symbol such as“ FF ”)” indicating a meta event. A “type” indicating the type of the event data, a “data length” indicating the length of the event data which is variable length, and a plurality of parameters necessary for displaying the score corresponding to the “type” Become. For example, in the case of a normal event for displaying a note head, “Head” is described in “Type”, and the note type (for example, a half note or a quarter note) or the pitch (for example, C4, E5, or the like). (Note number corresponding to the pitch of the sound), a temporary symbol attached to the note (for example, sharp (#), flat (♭), etc.), etc. are included as parameters. In the case of a normal event for displaying a tail (for example, a beam or flag), “Stem” is described in “Type”, and the number of notes, the direction of the tail (for example, top and bottom), the number of flags, The number of beams starting display and the number of beams starting display later are included as parameters. If it is a sub-event for displaying glissando symbols, “Glissando” is described in “type”, and the glissando start / start / end / end, glissando symbol display type (for example, wavy lines and glissando “gliss” display) Are displayed simultaneously, or only wavy lines are displayed) as parameters. In the case of an attribute event, “Attribute” is described in “Type”, and includes whether or not a note is displayed, that is, designation of an applied attribute such as “display / not display”. Of course, it goes without saying that the name of “type” and the types of parameters included in each event are not limited to those described above.
[0018]
The electronic musical instrument shown in FIG. 1 displays a score on the display 6A according to the score display data. When displaying a musical symbol of a type that connects notes and notes (for example, glissando, slur, portamento, choking, etc.) when displaying the score, one of the adjacent notes (or the same type of music) is displayed. If the symbols are continuous, both the successive notes are displayed or not displayed on the score. Such a score display process is performed by the CPU 1 in the electronic musical instrument shown in FIG. 1 executing a predetermined program (software) for realizing the score display process. The processing operation of this “score display processing” will be described with reference to FIG. FIG. 3 is a flowchart showing an example of “score display processing”. Hereinafter, the processing operation of the processing will be described according to the flowchart shown in FIG. However, here, a case where a glissando symbol is displayed as a musical symbol of a type that connects notes and notes will be described as an example.
[0019]
In step S1, an area for temporarily storing data, which is provided in a predetermined area on the RAM 3, in this embodiment, each data storage area for time data, note data, and glissando start data is initialized (cleared). . The time data stores timing data in the musical score display data. The note data stores as much information as can display the notes existing at a predetermined time on the score based on one or more score display data. The glissando start data stores information that can specify the display start position of the glissando symbol on the staff displayed on the display 6A. In step S2, one event data (timing data + musical score data) is read from the musical score display data specified in accordance with the music selection, and the event data is stored in the data storage area on the RAM 3. Hereinafter, for convenience of explanation, event data temporarily stored in the data storage area of the RAM 3 will be referred to as “Data”.
[0020]
In step S3, it is determined whether or not “Data” exists in the RAM 3. That is, in step S2, it is determined whether one event data can be read from the score display data, and the read event data is stored in the RAM 3. If it is determined that there is no “Data”, that is, if there is no event data to be read out in the score display data and the event data cannot be read out and stored in the RAM 3 (NO in step S3), the data is stored in the RAM 3. It is determined whether or not the note data exists and the display attribute information in the note data is set to “display” (ON) (step S4). When note data exists and the display attribute information is set to “display” (YES in step S4), the note is displayed on the staff notation displayed on the display 6A according to the note data (step S5), the process ends. On the other hand, if the note data does not exist in the RAM 3 in the first place or if the display attribute information is set to “not display” (OFF) (NO in step S4), the process is terminated without displaying the note. To do. If it is determined in step S3 that there is “Data”, that is, if one event data can be read from the score display data and the read event data can be stored in the RAM 3 (YES in step S3), It is determined whether or not the time data remains the initial value (step S6). If the time data remains the initial value (NO in step S6), the time data is updated to the “Data” time, that is, the time data is updated to the “Data” timing data (step S7).
[0021]
In step S8, it is determined whether the time of “Data” is equal to the time data. If they are not equal (NO in step S8), it is determined whether or not the note data exists in the RAM 3 and the display attribute information in the note data is set to “display” (ON). (Step S9). When note data exists and the display attribute information is set to “display” (YES in step S9), the note is displayed on the staff notation displayed on the display 6A according to the note data (step S9). S10). In step S11, the time data is updated to the time “Data” and the note data is cleared (initialized). In this way, when there is a note to be displayed at a display position corresponding to the timing data, and the note is set to “display”, it is displayed on the display 6A every time the timing data of the score display data changes. The note is displayed at the display position on the staff. In step S12, whether or not “Data” is a note event for displaying a note (that is, whether or not it is a normal event or a sub-event related to a note used for displaying a note), or a note It is determined whether or not the attribute event includes a parameter specifying “display / not display”. When “Data” is a note event or an attribute event including a parameter for specifying “display / not display” of a note (YES in step S12), the content of “Data” is set in the note data (step S12). S13) Returning to the process of step S2, the processes from step S2 to step S13 are repeated. That is, when the event data (normal event, sub-event, attribute event) related to the read note is the same timing data, the content of each event data is added to the note data. As a result, information relating to the note to be displayed at a predetermined display position on the staff notation displayed on the display 6A corresponding to the timing data is accumulated in the note data.
[0022]
If “Data” is not a note event or an attribute event including a parameter for designating “display / not display” of a note (NO in step S12) in step S12, each corresponds to the contents of “Data”. Processing is executed (step S14 to step S16). If “Data” is a sub-event designating the start of display of a glissando symbol (YES in step S14), the contents of “Data” are set in the glissando start data of RAM3 (step S17). When “Data” is a sub-event that specifies the start / end (Start / End) of the glissando symbol, or a sub-event that specifies the display end (end) of the glissando symbol (step S15 or step S16). YES), a glissando symbol is displayed on the staff score displayed on the display 6A in accordance with the contents of the glissando start data stored in the RAM 3, the contents of the note data and the contents of “Data” (step S18). Then, the glissando start data is cleared (initialized) (step S19). On the other hand, if “Data” is not a sub-event that defines the display start, display start / end, and display end of the glissando symbol as described above (NO in all of steps S14 to S16), the content of “Data” is If it can be displayed on the staff displayed on the display 6A, it is displayed (step S20). When the processes of step S17, step S19, and step S20 are completed, the process returns to step S2, one next event data is read from the score display data, and the processes are repeatedly executed.
[0023]
By doing as described above, it is possible to control whether or not to display a note on a score according to an attribute event including a parameter specifying “display / not display” in the score display data. Here, a specific example of the score displayed based on the score display data will be described for each content of the score display data. In each of the diagrams shown in FIGS. 4 to 6, the upper diagram shows an example of specific data definition in the score display data, and the lower diagram shows a display example of a score displayed based on the score display data. Is shown. 4 to 6, symbols a, b, c,...
