Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device such as a sequencer, an automatic accompaniment device, or an automatic rhythm performance device having a function of displaying performance data, and particularly to a display that is easy for a user to use when creating or editing performance data. The present invention relates to a performance data processing device and method.

  2. Description of the Related Art A sequencer-type automatic performance device that stores performance data (performance information) input from a keyboard of an electronic musical instrument, a computer, or the like and reproduces a performance sound based on the stored performance data has been conventionally known. In such an automatic performance device, the user can freely create performance data of the performance sound he wants to play, and the user can edit the stored performance data as desired. That is, the automatic performance device is provided with various functions so that the user can easily create and edit performance data. Among such functions, there is a function in which a performance data editing screen is displayed in a window on a screen in a predetermined format, so that a user can input, arrange, and edit performance data with a high degree of freedom. As a performance data editing screen displayed on a window, for example, the user can select block data (for example, every predetermined measure such as every bar) at any point in bar units or beat units divided into track units displayed on the screen. A track view window that allows you to compose a song by pasting the performance data that is delimited by), and inputting the performance data simply by pasting notes and symbols etc. into a musical score (for example, 5-line notation) A staff window that allows you to input performance data such as pitches in numerical values for each note. A list window that allows you to precisely input performance data such as pitch. Piano roll window for inputting data and rhythm parts Edit screen a variety is such that drum window. The user can simultaneously display a plurality of performance data editing screens of a desired format in a window, and can easily create and edit performance data from the window-displayed performance data editing screen. Power users can make full-fledged songs smoothly. Processing such as display and input of performance data on the performance data editing screen is performed by a performance data processing device.

  By the way, in a conventionally known performance data processing apparatus, when new performance data is created or desired existing performance data is edited, a performance data editing screen (for example, a track view window) of a predetermined format is always displayed. A window was displayed as the initial screen. However, a performance data editing screen (for example, a staff window or a piano roll window) to be used from the beginning may be determined by some users. Even in such a case, the conventional performance data processing apparatus uses an initial screen. Only the performance data editing screen of a certain format could be displayed on the window. For this reason, there is a problem in that the user has to input a predetermined command each time to display a performance data editing screen in a desired format on a window, and the input operation is troublesome.

  In addition, when a user newly creates or edits performance data, the user may use one or more point indices (hereinafter, referred to as markers) for designating an arbitrary position of the performance data displayed in the window, or a performance index. It is possible to set and input a predetermined repetition symbol or the like instructing repetition of the same sound, the same sound type and the same bar in the data. However, when both the marker and the repetition symbol are set and input at the same predetermined position on the performance data, the setting input positions overlap, and only at least one of the marker and the repetition symbol is displayed at the setting input position. . In other words, there is a problem that it is inconvenient to edit the performance data because the setting contents are difficult to understand for the user. Conventionally, a repetition symbol (for example, a repeat mark, dal segno, da capo, etc.) indicating that the performance of a large number of measures is to be repeated can be set and input. Or a repetition symbol that instructs to repeat the performance of the immediately preceding note in a bar (hereinafter, these symbols are particularly referred to as partial repeat symbols). There is also a problem that setting cannot be input for.

  Further, there is a display device which displays a chord name of a performance sound on a screen when a performance data editing screen is displayed on a window. However, when displaying the chord name, the chord name data stored in the performance data is displayed on the screen as it is, corresponding to the chord notation in a transposing instrument such as a wind instrument (for example, a trumpet or a saxophone). Since the chord name is not displayed, there is also a problem that the user who composes the music for the transposed instrument is inconvenient and inconvenient for editing the performance data.

  The present invention has been made in view of the above points, and when displaying a chord name of performance data, it is possible to change and display / input a chord name so as to correspond to a chord notation in a transposing instrument such as a wind instrument. It is an object of the present invention to provide an apparatus and a method for processing performance data.

  A performance data processing apparatus according to the present invention includes a display unit for displaying at least a chord name, a storage unit for storing performance data including at least a chord name, and a storage unit for displaying performance data for a transposed instrument. Control means for converting a chord name of the stored performance data into a chord name corresponding to the transposed musical instrument and controlling to display the chord name on the display means.

  The performance data is data that musically characterizes the music to be played, and the display means displays the performance data in a predetermined display format. When displaying performance data, the display means displays at least a chord name. The storage means stores performance data including at least a chord name. When an instruction is given to display the performance data in a display corresponding to the transposed instrument, the control means converts the code name of the performance data stored in the storage means into a code name corresponding to the transposed instrument and displays it. By doing so, even a user who uses the transposing instrument can easily edit the performance data.

  The invention can be constructed and implemented not only as a device invention, but also as a method invention. Further, they can be implemented by appropriately combining them. Furthermore, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, and can also be implemented in the form of a storage medium storing such a program.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a hardware block diagram showing the configuration of an electronic musical instrument incorporating a performance data processing device according to the present invention.

  The electronic musical instrument is controlled by a microcomputer including a microprocessor unit (CPU) 1, a program memory 2, and a working memory 3. The CPU 1 controls the operation of the entire electronic musical instrument. For the CPU 1, a program memory 2, a working memory 3, a key press detection circuit 4, a detection circuit 5, a display circuit 6, a sound source circuit 7, an effect circuit 8, an external storage device 9, a MIDI memory, via a data and address bus 1D. An interface (I / F) 10 and a communication interface 11 are connected to each other. The CPU 1 is connected to a timer 1A that measures an interrupt time and various times in a timer interrupt process.

  The program memory 2 stores various programs executed or referred to by the CPU 1, various data, and the like, and is configured by a read-only memory (ROM) or the like. The working memory 3 temporarily stores various information related to performances and various data generated when the CPU 1 executes a program. A predetermined address area of a random access memory (RAM) is assigned to each of the working memories 3. Used as a flag. The keyboard 4A is provided with a plurality of keys for selecting the pitch of musical tones, and has a key switch corresponding to each key. This keyboard 4A can be used for playing musical tones. , Can also be used as input means for performance data. The key press detection circuit 4 detects the press and release of each key of the keyboard 4A and generates a detection output. Note that the keyboard 4A may include various operators for inputting various music conditions related to the performance music. For example, it may include various operators such as a numeric keypad for inputting numerical data and panel switches for selecting, setting, and controlling pitches, timbres, effects, and the like. The mouse 5A designates the position of a music piece displayed on the display 6A to input various music conditions relating to the music piece, or performs a predetermined process (for example, a window display of a music data editing screen displayed on the display 6A). To perform on / off operations and block data or musical note paste operations on the performance data editing screen). The mouse detection circuit 5 detects the operation state of the mouse 5A, and outputs information corresponding to the operation state to the CPU 1 via the data and address bus 1D. The display circuit 6 displays various information such as the control state of the CPU 1 and the contents of the performance data on a display 6A composed of, for example, a liquid crystal display panel (LCD) or a CRT.

  The tone generator 7 can simultaneously generate tone signals on a plurality of channels, inputs data and performance information given via an address bus 1D, and generates tone signals based on the data. The tone signal generated by the tone generator 7 is generated via the sound system 8A. Further, the effect circuit 8 gives various effects to the tone signal generated from the tone generator circuit 7. Any tone signal generation method may be used in the tone generator circuit 7. For example, a waveform memory reading method for sequentially reading out musical tone waveform sample value data stored in a waveform memory according to address data that changes in accordance with a pitch of a musical tone to be generated, or a method in which the address data is used as a predetermined A known method such as an FM method for performing tone modulation sample value data by executing a frequency modulation operation or an AM method for executing tone amplitude sample value data by executing a predetermined amplitude modulation operation using the address data as phase angle parameter data. May be appropriately adopted. Further, the tone generator circuit is not limited to the one that uses the dedicated hardware, and the tone generator circuit may be configured using a DSP and a microprogram or a CPU and a software program. Further, these may be used in combination. Further, a plurality of tone generation channels may be formed by using one circuit in a time sharing manner, or one tone generation channel may be formed by one circuit.

  The external storage device 9 stores performance data such as performance data (to be described later) and rhythm patterns, and data related to control of various programs executed by the CPU 1. When the control program is not stored in the ROM 2, the control program is stored in the external storage device 9 (for example, a hard disk), and is read into the RAM 3 to store the control program in the ROM 2. Similar operations can be performed by the CPU 1. By doing so, it is possible to easily add a control program or upgrade the version. The external storage device 9 is not limited to a hard disk (HD), but may be a floppy disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), or a DVD (for Digital Versatile Disk). It may be a storage device using various removable storage media.

  The MIDI interface (I / F) 10 is for inputting MIDI standard performance information from another MIDI device 10A or the like outside the electronic musical instrument, or for outputting MIDI performance information to the outside of the electronic musical instrument. The communication interface 11 is connected to a communication network 11B such as a LAN, the Internet, or a telephone line. The communication interface 11 is connected to the server computer 11A via the general communication network 11B, and transmits control programs and various data from the server computer 11A. This is for taking in the musical instrument device side. That is, when the control program and various data are not stored in the ROM 2 or the hard disk, it is used to download the control program and various data from the server computer 11A. The electronic musical instrument device serving as a client transmits a control program and a command for requesting download of various data to the server computer 11A via the communication interface 11 and the communication network 11B. The server computer 11A receives this command, distributes the requested control program and data to the apparatus via the communication network 11B, and the apparatus receives the control program and various data via the communication interface 11. By storing the data on the hard disk, the download is completed. Note that the MIDI interface 10 is not limited to the one using a dedicated MIDI interface, and the MIDI interface is configured using a general-purpose interface such as RS232-C, USB (Universal Serial Bus), IEEE 1394 (Itriple 1394). You may do so. In this case, data other than the MIDI message may be transmitted and received at the same time.

  FIG. 2 is a diagram conceptually showing one embodiment of a data configuration of performance data employed in the present invention. The performance data processing device displays a musical score on the display 6A or reproduces the performance according to the performance data (see performance processing described later).

  Performance data is roughly divided into one master track data and a plurality of note track data. The master track data includes, for example, items for storing data relating to timing, chord names, markers, repetition symbols, etc., and is data commonly used for all note track data. The chord name data is data used for displaying a chord name and specifying a chord for automatic accompaniment. The marker data is data used to jump and display the pointer of the mouse 5A to the position at the time of data input. The repetition symbol data is data used for repeatedly controlling all note track data. Each note track data stores data used only in that track, such as note data and partial repeat symbols. Note data is data used for sound generation and mute. Partial repeat symbol data is data used to repeat one or more note data immediately before a partial repeat symbol in a certain track. The master track data and the note track data include the generation timing data of the data, and the contents of the data (for example, identification data indicating code name and code name data. And data). The timing data is recorded as a relative time from the previous data as an example. The timing data may be represented by an absolute time from the beginning of the music or the beginning of the bar. That is, the format of the performance data (master track data and each note track data) is of the “event + absolute time” format in which the occurrence time of the event (data content) is represented by the absolute time in a song or a bar, "Event + relative time" format in which the time is represented by the time from the previous event, "Pitch (rest)" in which the performance data is represented by the pitch and note length of the note or the rest and rest length What type of format, such as the “+ sign length” format, the “solid format” format where the memory area is secured for each minimum resolution of performance and the events are stored in the memory area corresponding to the time when the performance event occurs It may be. As described above, the timing data is data used for a position at which a chord name, a marker, a repetition symbol, or the like is displayed on a screen, or a sounding timing at the time of a performance.

  It goes without saying that the master track data may include, as items, other performance parameters relating to the entire music, such as timbre, tempo, and time signature, in addition to the items described above.

As shown in FIG. 2, the performance data is not limited to the one in which the master track data and each note track data are continuously stored in the storage area. Good. For example, the master track data and each note track data may be stored on separate memories. However, in this case, it is needless to say that scattered data must be separately managed as continuous data. For example, a table in which the master track data and each note track data are associated with each other may be prepared, and the performance data may be determined by referring to this table.
Further, the data of each note track may be mixedly stored in one track. In this case, track identification data may be added to each event.

FIG. 3 is a diagram conceptually showing an embodiment of a data configuration of a storage register of various setting values employed in the present invention.
The storage register is a register for storing various setting values input from the display by the user using a keyboard or a mouse. In this embodiment, the setting values of the default window, the setting values of the display filter, the code instrument type And data items that record The “setting value of the default window” is setting information (for example, “1” when the default window is opened) as to whether or not to open a window desired by the user (hereinafter referred to as a default window) as an initial screen. Is set to "0" when the default window is not opened) and the type of the default window (for example, a list window or a piano roll window). A plurality of windows can be set in the “default window type”, and the set plurality of default windows are opened (or not opened) according to the setting information. The “display filter setting value” is divided into marker display filter on / off information and repetition symbol display filter on / off information. The marker display filter on / off information is information for determining whether or not to display a marker on a window-displayed screen. For example, “1” is displayed when a marker is displayed, and “1” is displayed when a marker is not displayed. Is set to "0". The repetition symbol display filter on / off information is information for determining whether or not the repetition symbol is to be displayed on the screen displayed on the window. For example, when displaying the repetition symbol, "1" is displayed. If is not displayed, "0" is set. The "chord instrument type" records the type of instrument and the fundamental tone (tuning). For example, the instrument type is a "normal instrument" in the case of a musical instrument whose fundamental note is a "C" sound such as a piano, and an instrument whose fundamental note is not a "C" sound such as a trumpet or a saxophone (for example, the fundamental note in a trumpet is "Bb"). 'And the fundamental note in the alto saxophone is'Eb'), it is recorded as a “transposed instrument”. Of course, the present invention is not limited to this, and each instrument name may be recorded. In the case of a "transposed instrument", the fundamental tone of the instrument is recorded in "tuning" (for example, "Bb" is recorded for a trumpet, and "Eb" is recorded for an alto saxophone. ). However, when the musical instrument type is “normal musical instrument”, either the fundamental tone “C” may be recorded in “tuning” or not.

  It should be noted that the above-mentioned various setting value storage registers may be provided only as one common to all the performance data, or may be provided in plural to correspond to individual performance data. Good. In addition, a part of the various setting values may be common to all the performance data, and the rest may be provided for each performance data (for example, stored in the performance data). For example, only the chord instrument type may be provided for each piece of performance data. Further, it goes without saying that the storage register may include other data items in addition to the data items described above.

  FIG. 4 is a flowchart showing one embodiment of the performance processing executed by the performance data processing apparatus according to the present invention, and FIGS. 5 to 8 are flowcharts showing the details of each processing shown in FIG.

The performance process is started by a predetermined process such as power-on, and starts to be executed. First, in step S101, an initial setting process for performing various initial settings is performed. In step S102, window setting / display processing for setting the content of the performance data to be displayed in the window is performed. In step S103, an input item setting / display process is performed when there is an input from the user. In step S104, a performance sound reproduction process based on the performance data is performed. When the reproduction process is completed, the process returns to the process of step S101, and the above-described processes are repeated.
Hereinafter, the operation of each of the above-described processes will be described in detail with reference to the flowcharts of FIGS.

First, the initial setting process (step S101) will be described in detail. FIG. 5 is a flowchart illustrating an example of the initial setting process.
In step S1, a track view window is displayed. In the track view window, the user successively stores block data (for example, performance data divided into predetermined units such as one bar) at arbitrary points in measure units or beat units divided in track units displayed on the screen. (See FIG. 9 or FIG. 10, etc.), and the window is displayed as an initial screen in this embodiment. As can be understood from FIGS. 9 and 10, the track view window in the present embodiment is provided with processing selection fields such as “file”, “window”, and “setting” in the upper part of the screen, and the user can select the processing with the mouse 5A or the like. Desired processing can be performed by selecting a field. That is, a data field for displaying or inputting performance data is provided in the middle and lower parts of the screen, and block data can be displayed and input in the middle part of the screen and a chord name can be displayed in the lower part of the screen. It has become. Since such a track view window is already commonly used, a description thereof will be omitted.
Needless to say, the display items and formats of the track view window are not limited to those described above. That is, fields other than the fields described above may be provided, and each field may be displayed at any position.

Referring back to FIG. 5, in order to determine whether there is another window (default window) to be initially displayed together with the track view window, the setting value of the default window of the storage register is referred to (step S2). If the setting value of the referred default window is not the setting of “open default window” (NO in step S3), there is no need to open the default window as the initial screen, and the process jumps to step S5. If the set value of the referred default window is the setting of “open default window” (YES in step S3), the window set to the default window type is displayed as an initial screen simultaneously with the track view window (step S3). S4). For example, if the default window setting is "Open default window" and the window type set as the default window type is "Staff window", both the track view window and the staff are used. Are displayed on the display 6A so as to be overlapped (or arranged side by side). In step S5, other initial settings are performed. In other initial settings, for example, a sound source is set.
As described above, it is possible to automatically display a window of an arbitrary format at the time of starting the process, and it becomes unnecessary for the user to input an instruction command for displaying a desired window format. Very convenient to use.

  In the above description, an example of opening a new window at the time of initialization with respect to the default window has been described. However, when a new creation instruction is given by the user at an arbitrary time or when an existing performance data file is opened, the default window is opened. Window processing may be performed. Alternatively, the setting information of the default window may be stored for each performance data file, and a different type of window may be opened for each performance data file. Alternatively, setting information of a default window for each user may be stored, and a window of a different format may be opened for each user by inputting a user name when starting up the apparatus or the program. Also, the default window type is set to open / not open and the default window type is set separately. "Do not open default window" may be selectively set from options such as "Open / Do not open" and "Window type when opening" at the same time. . Also, a setting may be made such that a plurality of windows are opened at the same time (for example, a plurality of windows are displayed separately in an area).

Next, the window setting / display processing (step S102) will be described in detail. FIG. 6 is a flowchart showing one embodiment of the window setting / display processing.
In step S6, it is determined whether or not performance data to be edited of performance data has been read. When an instruction to read the performance data is issued to edit the performance data (YES in step S6), the performance data is read from the external storage device 9 or the like into the RAM 3, and the track view window and the above-described initial setting process ( The contents of the performance data are displayed according to the default window displayed in FIG. 5) (step S7). On the other hand, if the instruction to read the performance data has not been issued to create new performance data (NO in step S6), the process jumps to step S8 without performing the processing in step S7. In step S8, it is determined whether or not a change has been made to the "set value of the default window" in the storage register. That is, it is determined whether the setting of the default window displayed during the initial setting process has been changed. If the default window setting value has been changed (YES in step S8), the changed default window setting value is stored in the storage register (step S9). If the setting value of the default window has not been changed (NO in step S8), the process jumps to step S10.

  FIG. 9 shows a display example when the set value of the default window is changed. That is, in the window display (pop-up menu) opened according to the operation of the mouse 5A by the user, there are items named “default window” and “open default window”, and further “list”, “piano roll” “ A pop-up menu with windows such as "staff" and "drum" opens. The “default window” is an item for the user to select a default window to be displayed as a window as an initial screen. In this embodiment, the “staff” window is selected. “Open default window” is an item for selecting whether to open or not to open the default window as an initial setting. In the present embodiment, when setting to open the default window, a check display is performed at the left end thereof, and the default window is displayed. If you do not want to open the window, remove the check mark at the left end. That is, in the state shown in FIG. 9, the setting is such that the staff window is opened simultaneously with the track view window as the initial screen.

Returning to FIG. 6, in step S10, it is determined whether or not the set value of the display filter has been changed. If the set value of the display filter has been changed (YES in step S10), the changed set value of the display filter is stored (step S11). Then, the marker data and the repetition symbol data are read from the master track data, and the data whose display is turned on is displayed on the track view window (step S12). If the display of both the marker and the repetition symbol is off, neither is displayed.
FIG. 10 shows a display example when the set value of the display filter is changed. In this embodiment, unlike the case where the set value of the default window is changed, a new pop-up menu is displayed regardless of the field selection of the track view window, and the user selects a display filter from the pop-up menu. It has become. In the pop-up menu, there are items named “Add marker”, “Marker name” (M1, M2) and “Marker list”, “Display filter”, “Insert repeat” and “Repeat list”. The “display filter” further includes items named “marker” and “repeat symbol”. “Add marker” is an item used when a new marker is added. The “marker name” (M1, M2) and the “marker list” indicate the currently set marker. When M1 or M2 displayed as the “marker name” is selected, a pointer is set to the position of the marker. Etc. jump. On the other hand, the “marker list” displays a list of registered markers, and also displays a window in which a marker can be added, a position can be changed, or a marker can be deleted. The “display filter” is an item for setting a symbol (a marker or a repetition symbol) to be displayed on the screen. In the present embodiment, the display is performed by performing a check display at the left end of the “marker” or the “repetition symbol”. Can be set as follows. That is, only the markers (M1, M2) are displayed in the state shown in FIG. “Insert repeat symbol” is an item used when a new repeat symbol is added. The “repetition symbol list” displays a currently set repetition symbol and a window in which the position of the repetition symbol can be changed or deleted.

  Returning to FIG. 6, when the setting value of the display filter has not been changed (NO in step S10), the process jumps to step S13. That is, the process proceeds to the next process without changing the display position of the marker or the repetition symbol displayed in the track view window. In step S13, it is determined whether or not the setting value of the chord instrument type has been changed. If the set value of the chord instrument type has been changed (YES in step S13), the set value of the changed chord instrument type is stored (step S14). Then, the chord name data is read from the master track data, and the chord name transposed according to the chord instrument type is displayed on the track view window (step S15). If the setting value of the code instrument type has not been changed (NO in step S13), the process ends. That is, the process proceeds to the next process without changing the code name displayed in the track view window.

  FIG. 11 shows a display example when the setting value of the chord instrument type is changed. In this embodiment, when an instrument type data field for each track in the track view window is selected, a new window is displayed (instrument type setting dialog), and the user can set a chord instrument type from the dialog. It is supposed to do. The instrument type setting dialog includes items named “type” and “tuning”. “Type” is an item for selecting the type of instrument, and the type of instrument includes “normal instrument” and “transposed instrument”. "Tuning" is an item for determining a fundamental tone (tuning) by selecting a transposing instrument type (for example, soprano saxophone, alto saxophone, French horn, etc.) when "transposing instrument" is selected in "kind". In this embodiment, any one of a set of the instrument name and the fundamental tone (tuning) is selected and set. That is, in the state shown in FIG. 11, since the alto saxophone is selected as “tuning”, the fundamental tone (tuning) is “Eb”.

Here, the change display of the code name (step S15) will be briefly described.
As described above, the transposing instrument is an instrument having a fundamental tone other than 'C'. For example, the trumpet is generally based on the 'Bb' sound, and the C major scale for the trumpet is an actual sound and the Bb major scale. Therefore, the part of the trumpet must be transposed high (second major). However, a chord name on the C major scale is recorded in the chord name data of the master track data, and if the chord name is directly displayed as a transposed instrument code in the track view window, it is very difficult for the user to understand. Therefore, in order to display a chord suitable for the transposed instrument, the "chord name data" is transposed according to the fundamental tone recorded in "tuning" and displayed in the track view window.

In the above description, an example of displaying the marker and the repetition symbol in the track view window has been described. However, the display is performed in a window of another display format such as a staff window or a piano roll window. Is also good. Also, the display filter can be set on / off independently for the marker and the repetition symbol. However, the display filter can be set to “display only the marker”, “display only the repetition symbol”, “display both”, “do not display both”, etc. As described above, any one of a plurality of options having different on / off combinations may be selectively set.
Furthermore, with respect to the setting of the chord instrument type, an example has been shown in which one of the options in which the instrument name and the fundamental tone (tuning) is set is selected and determined. It may be set independently. Alternatively, a musical instrument icon in the shape of a musical instrument may be displayed instead of or in addition to the musical instrument name so that the fundamental tone can be selected and set by the musical instrument icon.

Next, the input item setting process (step S103) will be described in detail. FIG. 7 is a flowchart illustrating an embodiment of the input item setting process.
In step S16, it is determined whether or not a marker input (addition, position change, deletion, etc.) has been performed. That is, it is determined whether or not the user has added, changed the position, or deleted the marker. If a marker has been input (YES in step S16), the input marker is written into master track data (or erased in the case of marker deletion) (step S17). At this time, if the marker display filter is on (YES in step S18), the set marker is displayed in the track view window (step S19). If the marker has not been input (NO in step S16), the process jumps to step S20 without performing the above-described processes (the processes in steps S17 to S19).

  In step S20, it is determined whether an input of a repetition symbol (addition, position change, deletion, etc.) has been performed. If the repeat symbol has not been input (NO in step S20), the process jumps to step S24. If the repetition symbol has been input (YES in step S20), the input repetition symbol is written into the master track data (or erased if the repetition symbol is deleted) (step S21). Then, it is determined whether or not the display filter for the repetition symbol is turned on (step S22). If the repeat symbol display filter is on (YES in step S22), the input repeat symbol is displayed in the track view window. If the display filter of the repetition symbol is not turned on (NO in step S22), the process jumps to step S24.

Here, a brief description will be given of a method of displaying the marker and the repetition symbol when the marker and the repetition symbol are set at the same position or in the vicinity of the performance data. FIG. 12 is a conceptual diagram conceptually showing one embodiment of a display method for displaying a marker and a repetition symbol. However, in the present embodiment, only the display position where the marker and the repetition symbol in the track view window can be displayed is enlarged.
As can be understood from FIG. 12, when the marker and the repetition symbol are set at the same position on the performance data or in the vicinity thereof, if both the display filters are turned on, the marker name and the repetition symbol overlap, and the Hard to see. Therefore, if the display filter for only the repetition symbol is turned on or the display filter for only the marker is turned on, the marker and the repetition symbol do not overlap and are displayed, which makes it very easy for the user to see.
When the marker and the repetition symbol are set at the same position on the performance data or in the vicinity thereof, at least one of the markers and the repetition symbol is displayed at a position shifted from the original position so that both the marker and the repetition symbol are simultaneously displayed. Is also good. For example, the display of the marker may be shifted leftward or rightward (see another example). In this case, a display symbol (a downward triangle) indicating the original position may be displayed at the original position without shifting.
Also, when the display filter is turned off, the display of the marker or repetition symbol is not completely erased, but the display filter is turned on and displayed faintly with a light color etc. that does not disturb the displayed symbol You may make it.

  Returning to FIG. 7, in step S24, it is determined whether a code name has been input (addition, change, deletion, etc.). If the chord name has been input (YES in step S24), the input chord name is displayed in the track view window (or the display is deleted in the case of deleting the chord name) (step S25). Then, the code name obtained by transposing the input chord name according to the chord instrument type is written in the master track data (or deleted in the case of deleting the chord name) (step S26). That is, when the user inputs a transposed musical instrument chord on the track view window, the chord is changed to the chord name in the C major when recording the chord in the "chord name data". If the code name has not been input (NO in step S24), the process jumps to step S27. If the master track data is configured to record “chord name data” for each of the normal and transposed instruments, the chords for each instrument can be recorded without changing the chord name. It is needless to say that it is not necessary to change the code name and record (or display) it. In this case, it is necessary to also record which transposed instrument the chord name is recorded. In step S27, it is determined whether or not the input (addition, position change, deletion, etc.) of the partial repeat symbol in the staff window has been performed. If a partial repeat symbol is input in the stuff window (YES in step S27), the input partial repeat symbol is displayed in the stuff window (or the display is erased in the case of partial repeat symbol deletion) (step S27). S28). Then, the input partial repeat symbol is written into the track data corresponding to the stuff window (or erased when the partial repeat symbol is deleted) (step S29).

Here, the partial repeat symbol will be briefly described.
FIG. 13 is a conceptual diagram conceptually showing one embodiment of an input screen for a partial repeat symbol. 14A and 14B are explanatory diagrams for explaining the input of a partial repeat symbol. FIG. 14A is a diagram for explaining a partial repeat in beat units, and FIG. 14B is a diagram for explaining a partial repeat in bar units. It is.
The beat-based partial repeat symbol is a copy of a preceding beat-based note in beat units (see the upper diagram in FIG. 14A). When such a partial repeat symbol is input on the window, it can be input even if the user has input a slightly shifted upper, lower, left, or right position (see the middle and lower diagrams in FIG. 14A). The bar-based partial repeat symbol is a copy of the immediately preceding bar-based note in bar units (see the upper diagram in FIG. 14B). Even when such a partial repeat symbol is input on the window, it can be input even if the user inputs the bar in the bar up, down, left, and right with a slight shift (see the middle and lower diagrams in FIG. 14B). . As described above, the partial repeat symbol can be input at any position on the window according to the user's preference. Of course, it is needless to say that a desired note or rest can be input after these partial repeat symbols to create and edit performance data. Further, another note may be newly input in the same beat or the same bar. In this case, a state of “copied forward note + newly input other note” is obtained.

  When the user inputs a partial repeat symbol on the window, the partial repeat symbol is recorded in the track data (see FIG. 2). When recording a partial repeat symbol, timing data is also recorded in the track data, but this timing data is used to determine the position where the partial repeat symbol is displayed when displaying the partial repeat symbol on the window. Is the data to be processed. For example, the timing data in the partial repeat symbols input at the positions shown in the upper, middle and lower parts of FIG. 14B are recorded differently, and if the timing of the upper part is “2”, the timing of the middle part is It becomes “1” and is recorded as “3” in the lower diagram. Then, the partial repeat symbol is arranged and displayed at a predetermined position on the window corresponding to each timing data. Note that data for determining the vertical position on the display may also be recorded.

Next, the performance data reproduction process (step S104) will be described. FIG. 8 is a flowchart showing one embodiment of the performance data reproducing process.
In step S30, it is determined whether a reproduction instruction has been issued. If the reproduction instruction has not been issued (NO in step S30), the process jumps to step S34. On the other hand, when the reproduction instruction is given (YES in step S30), the data of each note track data is processed (that is, the repetition part is reflected) based on the repetition symbol data of the master track data, and the data is stored in the reproduction buffer. Is copied (step S31). The partial repeat number of each note track in the playback buffer is searched, and the beat or measure unit immediately before the found partial repeat number (beat unit or measure unit is determined according to the type of the partial repeat symbol) The note data is copied in beats or measures after the immediately preceding note data (step S32). Then, a predetermined reproduction process is started (step S33), and the performance is started according to the performance data. The reproduction process (step S33) is executed at a predetermined processing cycle (for example, a timer interrupt process), but the predetermined cycle may be a cycle corresponding to the tempo or a cycle independent of the tempo. . That is, a method of changing the processing cycle according to the set tempo, a method of changing the value of the timing data during automatic performance according to the set tempo while the processing cycle is constant, In the above, any processing method such as a method of changing the counting method of the timing data in the performance data according to the tempo may be used. As an example, there is one that executes the reproduction processing at a cycle of 1 / 96th of a quarter note. In step S34, "other processing" is performed.

  Note that, with respect to the partial repeat symbol, note data reflecting the partial repeat symbol is created when a reproduction instruction is issued, but note data reflecting the symbol is created when the partial repeat symbol is input. It may be. When storing the performance data file, note data reflecting the symbol may be created. Further, note data reflecting the symbol may be displayed in a staff window, a piano roll window, or the like.

  The electronic musical instrument is not limited to a keyboard instrument, but may be a string instrument, a wind instrument, or a percussion instrument. Further, in the above-described embodiment, the description has been given of the case where the sound source device, the automatic performance device, and the like are incorporated in one electronic musical instrument main body. However, the present invention is not limited to this. It goes without saying that the present invention can be similarly applied to a device configured to connect each device using a communication unit. Further, the configuration may be a configuration of a personal computer and application software. In this case, the processing program may be supplied from a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, or may be supplied via a network. Further, the present invention may be applied to creation of performance data used for a karaoke device, or may be applied to an automatic accompaniment device.

According to the above embodiment, since the user can automatically open the window of the desired format, it is not necessary to perform a predetermined operation for opening the window of the desired format each time. This makes it possible to immediately edit the performance data without performing the editing.
Also, since markers and repetition symbols are not displayed overlapping on the window, or chord names are displayed on the window corresponding to transposing instruments, users can create and edit performance data. Is easily performed.
Further, since the input of the partial repeat symbol and the performance corresponding to the input can be performed, it is possible to obtain an effect that the user can perform more various musical expressions.
