Abstract

PROBLEM TO BE SOLVED: To easily grasp the position of a song position during editing of sequence data.SOLUTION: An edition object area is cut out from a piano roll, a scroll bar 210c having a virtual knob for moving the edition object area in a time axis direction is added thereto, and the edition object area and the scroll bar are displayed on a display device; and a song position mark SPM corresponding to the song position SP is displayed on the scroll bar 210c. Here, when the song position SP is set outside the edition object area, the display position of the song position mark SPM is calculated by making the position of an end part of the virtual knob in the scroll bar 210c correspond to the position of an end part of the edition object area in a note input area of the piano roll, and on the other hand, when the song position SP is set within the edition object area, the display position is calculated by making the length of the virtual knob in the time axis direction correspond to the length of the edition object area in the time axis direction.

Description

  The present invention relates to a technique for supporting editing of sequence data representing a melody of a song.

  DTM (Desktop Music) technology for editing and playing music using a computer is generally popular, and an example thereof is the song synthesis technology disclosed in Patent Document 1. In DTM, a GUI imitating a piano roll (hereinafter simply referred to as “piano roll”) representing information representing a series of musical notes that compose the melody of a song (in the case of song synthesis, lyrics that are pronounced along with the musical notes). Sequence data to be input by the user and to control driving of the sound source is generated based on the information. Since all the notes constituting the melody of the music are described in the piano roll, the length of the piano roll in the time axis direction is determined according to the length of the music to be edited. For this reason, depending on the length of the music, it may be difficult to display the entire piano roll collectively. Therefore, the display area is cut out from the entire piano roll using a display frame having a predetermined length such as several bars in the time axis direction and displayed on the display device, and the display frame is displayed on the time axis by operating a scroll bar or the like. It is generally done to move in the direction.

JP-A-11-352997

  By the way, in DTM, in order to facilitate the editing work, the song roll position where the note start position for receiving the input of a new note or the like when the playback start position when the sequence data being edited is played back as a sound is the piano roll Set on the time axis. However, if the display frame is gradually moved in the time axis direction, the song position is out of the display area and is not displayed. When it is necessary to return the display frame to the song position again, it is necessary to deal with it by operating the scroll bar, etc., but in which direction of the time axis the display frame should be moved. There are cases where it cannot be grasped instantaneously.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique for easily finding a song position during editing of sequence data.

  In order to solve the above-described problem, the present invention inputs a series of notes constituting the melody of the song via a piano roll having a note input area having a length corresponding to the song length of the song to be edited. In the editing apparatus that generates sequence data representing the display area, (A) a display unit, and (B) a part of the note input area is displayed using a display frame having a predetermined length in the time axis direction of the piano roll. Piano roll display processing to be displayed on the display unit together with a scroll bar having a virtual knob for moving the display frame along the time axis, and a playback start position when the sequence data being edited is played as sound Alternatively, a process for displaying on the scroll bar a mark corresponding to a position set on the time axis as a note input position for receiving a new note input. The positions of both ends of the virtual knob on the scroll bar correspond to the positions of both ends of the display area on the time axis, and the display closer to the position from the position set on the time axis The display position of the mark is calculated by associating the distance to the end of the region with the distance from the display position of the mark to the end of the virtual knob corresponding to the end, and the mark is displayed at the display position. There is provided a sequence data editing device characterized by having a control unit for executing mark display processing.

  As described above, the song position is a reproduction start position when reproducing the sequence data being edited as a sound, or a note input position that accepts input of a new note or the like. Therefore, according to the present invention, the mark corresponding to the song position is displayed on the scroll bar. For this reason, even if the song position moves out of the display area in the process of editing sequence data, the user can display the display frame up to the position of the song position based on the relative positional relationship between the mark and the virtual knob on the scroll bar. It is possible to instantly grasp whether the virtual knob should be operated in the direction of the beginning of the song or the end of the song. As another aspect of the present invention, a program for causing a computer to execute the piano roll display process and the mark display process may be distributed. As a specific distribution aspect of the program, a CD- A mode in which data is written and distributed on a computer-readable recording medium such as a ROM (Compact Disk-Read Only Memory) or a mode in which the data is distributed by download via telecommunications such as the Internet can be considered.

  As a specific calculation mode of the display position of the mark corresponding to the song position, when the position set on the time axis is included in the display area, the width of the display area in the time axis direction Corresponding to the width of the virtual knob in the time axis direction, the display position of the mark is calculated, and when the position set on the time axis is on the tune start side with respect to the display area, The display position is calculated by making the distance to the position correspond to the distance from the top of the scroll bar to the display position of the mark, and the position set on the time axis is closer to the end of the music than the display area. In some cases, the display position is calculated by associating the distance from the end of the song to the position with the distance from the end of the scroll bar to the display position of the mark. According to such a calculation mode, the width of the virtual knob in the time axis direction is changed according to the ratio of the display area to the entire note input area (for example, if the ratio is a predetermined value or more, the ratio is set to the ratio). Accordingly, the width of the virtual knob in the time axis direction is changed, and if the ratio is less than the predetermined value, the width of the virtual knob in the time axis direction is fixed). The above mark is not displayed on the virtual knob even though it is set, or the song position is set on the virtual knob even though the song position is set to the beginning (or end) of the song. The occurrence of inconsistencies such as the display of the mark is avoided. This point will be described in detail later.

  Here, the mark corresponding to the song position may be displayed at any time regardless of the relative positional relationship between the display frame on the time axis and the song position. The mark may be displayed when the position is out of the display frame. At least if the above mark is displayed when the song position is out of the display frame, the user can instantly determine which direction to operate the virtual knob when returning the display frame to the position of the song position. It is because it can be made to grasp.

  In a more preferred aspect, in the mark display process, the control unit sets the positions of both ends of the virtual knob on the scroll bar on the time axis for auxiliary information indicating the configuration of the song to be edited in the time axis direction. The auxiliary information on the scroll bar is defined as the distance from the position on the time axis represented by the auxiliary information to the end of the display area closer to the position, corresponding to the positions of both ends of the display area. The display position of the auxiliary information is calculated in correspondence with the distance from the display position to the end of the virtual knob corresponding to the end, and the auxiliary information is displayed at the display position. As another preferable aspect, the display area is cut out using a display frame having a predetermined length in the pitch axis direction intersecting the time axis, and the display frame is moved along the pitch axis. In the process of displaying on the display unit together with the scroll bar having the virtual knob for the mark and the mark display process, the position of both ends of the virtual knob on the scroll bar is displayed on the pitch axis for the auxiliary information indicating the pitch. The auxiliary information on the scroll bar is a distance from the position on the pitch axis corresponding to the position of both ends of the area and corresponding to the pitch indicated by the auxiliary information to the end of the display area near the position. The display position of the auxiliary information is set in correspondence with the distance from the display position of the virtual knob to the end of the virtual knob corresponding to the end. Out is the process for displaying the auxiliary information on the display position also considered aspects to be executed by the control unit.

It is a figure which shows an example of the musical editor screen displayed on the display part 120a of the song synthesizing | combining apparatus 10. FIG. It is a figure for demonstrating the calculation method of the display position of the song position mark SPM in this embodiment.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration example of a singing voice synthesizing apparatus 10 that functions as an editing apparatus according to an embodiment of the present invention. This singing voice synthesizing apparatus 10 has a singing voice synthesizing database (not shown in FIG. 1) in which waveform data of a large number of voice segments are made into a database, and synthesizes a singing voice by connecting these voice segments. It is. As shown in FIG. 1, the singing voice synthesizing apparatus 10 includes a control unit 110, a user I / F unit 120, a storage unit 130, and a bus 140 that mediates data exchange between these components. The control unit 110 is, for example, a CPU (Central Processing Unit). The control unit 110 functions as a control center of the singing voice synthesizing apparatus 10 by executing a program stored in the storage unit 130.

  The user I / F unit 120 is for providing various user interfaces for allowing the user to use the singing voice synthesizing apparatus 10. As shown in FIG. 1, the user I / F unit 120 includes a display unit 120a, an operation unit 120b, and an audio output unit 120c.

  The display unit 120a is, for example, a liquid crystal display and its drive circuit. Various editing screens for realizing singing synthesis are displayed on the display unit 120a. Examples of the editing screen displayed on the display unit 120a include a musical editor screen and a track editor screen. The musical editor screen is an editing screen that prompts the user to edit the sequence data (track data) that represents the melody of the part and the lyrics that are pronounced according to the melody for each part of the song, such as the main vocal part and chorus part. is there. As the musical editor screen, a screen simulating a piano roll is used as in the conventional synthesizer. On the other hand, the track editor screen displays the sound waveform of each track data generated for each part as a thumbnail, and allows the user to edit the singing voice of the entire song to be edited, such as adjusting the volume balance of each part. It is an edit screen for.

  The operation unit 120b is a pointing device such as a mouse or a keyboard, for example. When an operation is performed on the operation element (left and right buttons of the mouse and various keys of the keyboard), the operation unit 120b delivers operation content data corresponding to the operation content to the control unit 110. Thereby, the content of the operation performed by the user on the operation unit 120b is transmitted to the control unit 110, and the control unit 110 executes a process according to the operation content. The audio output unit 120c includes a sound source circuit that outputs an audio signal under the control of the control unit 110, and a speaker that outputs an audio signal output from the sound source circuit as sound (none of which is shown). This audio output unit 120c is used when confirming the sensation of the music represented by the sequence data being edited.

The storage unit 130 includes a nonvolatile storage unit 132 and a volatile storage unit 134.
The nonvolatile storage unit 132 is, for example, a hard disk. The non-volatile storage unit 132 stores the above-described song synthesis database (not shown) and also stores a song synthesis program 132a. On the other hand, the volatile storage unit 134 is, for example, a RAM (Random Access Memory), and is used as a work area when the singing synthesis program 132a is executed. Examples of processing executed by the control unit 110 according to the singing synthesis program 132a include editing processing and singing synthesis processing. The editing process is a process that supports editing of music by prompting input of notes constituting the melody of the music, lyrics to be sung along with the music notes, information indicating the pronunciation of the lyrics, and the like. On the other hand, the singing synthesis process is a process of synthesizing a singing voice according to the editing content in the editing process. Of these two processes, the singing composition process is not particularly different from that in the conventional singing composition apparatus, and therefore the description thereof will be omitted, and the following description will focus on the editing process.

  As shown in FIG. 1, the editing process of the present embodiment includes a musical editor process and a track editor process. The musical editor process is a process in which a musical editor screen is displayed on the display unit 120a to prompt editing of track data of each part and input of lyrics of the part. On the other hand, the track editor process is a process for displaying the track editor screen on the display unit 120a and prompting the adjustment of the volume of each part. Of these two processes, the track editor process is not particularly different from that in the conventional singing voice synthesizing apparatus. Therefore, detailed description thereof will be omitted, and the following will focus on the musical editor process.

  The musical editor process of this embodiment includes a piano roll display process and a mark display process as shown in FIG. The piano roll display process is a piano roll 210 (see FIG. 5) that prompts the user to input a series of notes representing the melody of the part designated for editing, lyrics to be pronounced in accordance with the notes, and control data indicating the pronunciation of the lyrics. 2) display control. As shown in FIG. 2, the piano roll 210 extends in a time axis direction orthogonal to a pitch display area 210a simulating a piano keyboard and a piano keyboard arrangement direction (hereinafter referred to as a pitch axis direction) in the pitch display area 210a. And a note input area 210b for inputting existing notes. The note input area 210b has a length corresponding to the length of the song to be edited. The left end is at the beginning (top of the song) and the right end is at the end (end of the song). It corresponds. As shown in FIG. 2, the note input area 210b is divided into a plurality of cells in the pitch axis direction and the time axis direction. The plurality of cells correspond to the pitch indicated by each key of the piano keyboard of the pitch display area 210a, and the division unit in the time axis direction of the plurality of cells is a beat (1 beat or 1/2 beat) unit. . In the present embodiment, as shown in FIG. 2, by writing lyrics in a plurality of cells that are continuous in the time axis direction, it is possible to specify a pitch and a pronunciation time (ie, a note) when the lyrics are pronounced, Furthermore, by drawing a wavy line indicating the sound generation mode (for example, fine pitch fluctuation or inflection) in association with each lyrics, it is possible to input control data indicating the sound generation mode.

  In the piano roll display process, as shown in FIG. 2, the control unit 110 uses a display frame (shown by a dotted line in FIG. 2) having a predetermined time length (for example, several bars) in the time axis direction. A part of the note input area 210b is cut out as the display area EA, and is displayed on the display unit 120a together with the scroll bar 210c for moving the display frame in the time axis direction and the image of the pitch display area 210a. The screen displayed on the display unit 210a in this way is the musical editor screen. Note that the length of the section cut out from the note input area 210b as the display area EA (that is, the length of the display frame in the time axis direction) may be appropriately set by the user. As shown in FIG. 2, the scroll bar 210c is provided with a virtual knob 210d for receiving an operation of moving the display frame in the time axis direction. The width of the virtual knob 210d in the time axis direction depends on the ratio while the ratio of the display area EA occupying the entire note input area 210b (for example, the ratio of the widths in the time axis direction) is a predetermined value or more. It is determined (for example, in proportion), and is set to a fixed value when the ratio falls below the predetermined value. This is to prevent the operation of the virtual knob 210d from becoming too narrow and hindering the operation. The virtual knob 210d is a display area EA when the length of the scroll bar 210c in the time axis direction corresponds to the length of the entire note input area 210b in the time axis direction (that is, the length of the song to be edited). Is placed at a position corresponding to. That is, the position of the left end of the virtual knob 210d on the scroll bar 210c corresponds to the position of the left end (end on the tune side) of the display area EA, and the position of the right end of the virtual knob 210d is the right end (curve of the display area EA). Corresponds to the position of the end of the end.

  A user who visually recognizes the musical editor screen shown in FIG. 2 selects a song start position (see FIG. 2) that is a playback start position when playing back the sequence data being edited as a sound or a note input position for receiving an input of a new note. Can be set. In addition, it is possible to perform an auto scroll setting or the like regarding whether or not to move the song position SP along with music reproduction. In the present embodiment, the control unit 110 executes the mark display process when the song position SP is set. The mark display processing calculates the display position when the song position mark SPM corresponding to the song position SP (in FIG. 2, a line segment parallel to the pitch axis) is displayed on the scroll bar 210c, and the song position is displayed at the display position. This is processing for displaying the mark SPM.

  In the mark display process of the present embodiment, the control unit 110 determines the distance in the time axis direction from the end of the display area EA on the side close to the song position SP to the song position SP of the virtual knob 210d corresponding to the end. Calculation is performed in correspondence with the distance from the end to the display position of the song position mark SPM. More specifically, the control unit 110 determines that the song position SP is closer to the beginning of the song than the display area EA (hereinafter, Case 1), and the song position SP is within the display area EA (hereinafter, Case 2). , And the case where the song position SP is located at the end of the song from the display area EA (hereinafter referred to as case 3), the display position of the song position mark SPM in each case is calculated in the following manner.

(Case 1) In this case, as shown in FIG. 3A, the control unit 110 moves from the beginning of the song to be edited (the left end of the note input area 210b) to the left end of the display area EA (ie, at the song position SP). Distance LB to the end on the near side (in this embodiment, distances measured in beats such as 1 beat and 1/2 beat, and the same applies to distances SBL, SPL, SPR, SBR, and RB described later), Position SB (LB> SB) from the beginning of the song to the song position SP and the position coordinate SL in the time axis direction of the left end (that is, the top) of the scroll bar 210c when the upper left corner of the display surface of the display unit 120a is the origin of coordinates. , And the position coordinate KL in the time axis direction of the left end of the virtual knob 210d (that is, the end corresponding to the left end of the display area EA), the time axis direction of the song position mark SPM The position coordinates SPP calculated so as to satisfy the following equation (1).
SBL / LB = (SPP-SL) / (KL-SL) (1)
The distance LX from the song position SP to the left end of the display area EA is equal to LB-SBL, and the distance from the song position mark SPM to the left end of the virtual knob 210d is equal to KL-SPP. Therefore, the position coordinate SPP of the song position mark SP should be calculated according to the following equation (1) ′.
LX / LB = (KL-SPP) / (KL-SL) (1) ′
Here, the above formula (1) is obtained by rearranging the formula (1) ′ in consideration of LX = LB−SBL. That is, calculating the position coordinate SPP of the song position mark SPM in the time axis direction according to the equation (1) is calculating the position coordinate SPP according to the equation (1) ′ (that is, from the song position SP to the display area EA). Is equivalent to the distance from the song position mark SPM to the corresponding end of the virtual knob 210d).

(Case 2) In this case, as shown in FIG. 3B, the control unit 110 performs a song from the left end of the display area EA, the width in the time axis direction of the display area EA (the width measured in beats) NB. Using the distance SBL in the time axis direction to the position SP, the position coordinate KL in the time axis direction on the left end of the virtual knob 210d and the position coordinate KR on the right end when the upper left corner of the display surface of the display unit 120a is the coordinate origin. The position coordinate SPP of the song position mark SPM in the time axis direction is calculated so as to satisfy the following equation (2).
SBL / NB = (SPP-KL) / (KR-KL) (2)

  In the present embodiment, when the set position of the song position SP is on the song start side with respect to the center of the display area EA (that is, when the end of the display area EA on the side close to the song position SP is the left end). Of course, the position coordinate SPP of the song position mark SPM in the time axis direction is calculated according to the equation (2) even when the set position of the song position SP is located at the end of the song from the center of the display area EA. The reason is as follows.

When the setting position of the song position SP is at the end of the song from the center of the display area EA, the end of the display area EA on the side close to the song position SP is the right end. Therefore, in this case, the position coordinate of the song position mark SPM in the time axis direction according to the following equation (3) based on the distance SLR (see FIG. 3B) between the right end of the display area EA and the song position SP. SPP 'should be calculated.
SBR / NB = (KR-SPP ') / (KR-KL) (3)

Here, as shown in the following equation (4), when the difference between the SPP calculated according to the equation (2) and the SPP ′ calculated according to the equation (3) is calculated, the difference between the two becomes zero. Note that SBL + SBR = NB was used in the calculation of equation (4) (see FIG. 3B).
SPP−SPP ′ = {(KR−KL) × SBL / NB + KL}
− {− (KR−KL) × SBR / NB + KR}
= (KL-KR) + (KR-KL) * (SBL + SBR) / NB
= 0 (4)

  That is, the calculation shown in Expression (2) and the calculation shown in Expression (3) are completely equivalent. Therefore, if the song position mark SPM is calculated using the equation (2) regardless of whether the set position of the song position SP is on the tune start side or the song end side with respect to the center of the display area EA, The distance in the time axis direction from the end of the display area EA closer to the song position SP to the song position SP is the distance from the end of the virtual knob 210d corresponding to the end to the display position SPP of the song position mark SPM. It is calculated according to the distance. This is the reason why the song position mark SPM is calculated using the equation (2) regardless of whether the set position of the song position SP is on the song head side or the song end side with respect to the center of the display area EA.

(Case 3) In this case, as shown in FIG. 3C, the control unit 110 displays the right end of the display area EA (as shown in FIG. 3C, the display near the song position SP). The distance RB in the time axis direction from the end of the area EA to the end of the song to be edited, the distance SBR from the right end to the song position SP (RB> SBR), and the upper left corner of the display surface of the display unit 120a are coordinated The position coordinate SR in the time axis direction of the right end (the end of the scroll bar 210c) of the scroll bar 210c and the position of the right end of the virtual knob 210d (the end corresponding to the right end of the display area EA) in the time axis direction when the origin is set. Using the coordinate KR, the position coordinate SPP of the song position mark in the time axis direction is calculated so as to satisfy the following equation (5).
SBR / RB = (SPP-KR) / (SR-KR) (5)

  The reason why the calculation method of the display position SPP of the song position mark SPM is changed in accordance with the relative positional relationship between the display area EA and the song position SP on the time axis in the present embodiment is as follows. As described above, the length of the virtual knob 210d in the time axis direction is basically proportional to the number of bars cut out as the display area EA, but the size of the display area EA relative to the entire note input area 210b is a constant value. Is less than, the length of the virtual knob 210d in the time axis direction becomes a fixed value regardless of the number of bars, and the proportional relationship is not established.

  If the display position SPP of the song position mark SPM is simply calculated as “the length of the scroll bar 210c × the position of the song position SP / the length of the song to be edited”, the above proportional relationship does not hold. Then, although the song position is displayed in the display area EA, the contradiction that the song position mark SPM is not displayed on the virtual knob 210d, or the song position SP is set to the left (or right) of the display area EA. Nevertheless, a contradiction may occur such that the song position mark SPM is displayed on the virtual knob 210d.

On the other hand, if the calculation formula for the display position SPP of the song position mark SPM is switched in accordance with the relative positional relationship between the display area EA and the song position SP on the time axis, these contradictions will occur. Absent. For example, in the case 1, since LB> SB, the expression (1) is evaluated as the following expression (6), and when KL> SL is noted and the SPP is solved, KL> SPP is obtained. That is, the display position SPP of the song position mark SPM is always on the tune start side with respect to the left end of the virtual knob 210d, and no contradiction occurs.
(SPP-SL) / (KL-SL) = SB / LB <1 (6)

  In the case of (Case 2), SPP <KR is guaranteed from the right side of Expression (2), and SPP ′ (= SPP)> KL is guaranteed from the right side of Expression (3) equivalent to Expression (2). . Therefore, the display position SPP of the song position mark SPM is on the virtual knob 210d, and no contradiction occurs. Further, in the case of (Case 3) as well, when Formula (5) is evaluated in consideration of SBR> 0 and SR-KR> 0, SPP-KR> 0, that is, SPP> KR. . That is, the display position SPP of the song position mark SPM is always at the end of the song from the right end of the virtual knob 210d, and no contradiction occurs.

Thus, according to the present embodiment, the above-described contradiction does not occur in any of cases 1 to 3. In other words, in order to prevent the above contradiction, in this embodiment, the calculation formula for the display position of the song position mark SPM is switched according to the relative positional relationship between the display area EA and the song position SP. It is.
The above is the configuration of the singing voice synthesizing apparatus 10 of the present embodiment.

Next, the effect of this embodiment will be described according to the use case of the singing voice synthesizing apparatus 10.
(1) Effect of playing the song being edited with auto scrolling of the song position SP turned off In this case, since the auto scrolling of the song position SP is turned off, Along with the movement, the song position SP deviates from the display area EA. In such a music playback process, it is assumed that the user finds a part that the user is not satisfied with and performs an operation to stop the music playback at that location, thereby stopping the music playback. When the operation is performed, if the song position SP is out of the display area EA and the display frame needs to be returned to the position of the song position SP, the user operates the virtual knob 210d to display it. It is necessary to move the frame in the time axis direction. In such a case, conventionally, it has not been possible to instantaneously grasp whether the song position SP is located at the beginning or end of the song when viewed from the display area EA. Since the position mark SPM is displayed on the scroll bar 210c, the user can use the clue to the positional relationship between the song position mark SPM and the virtual knob 210d as the song position SP is viewed from the display area EA. It can be easily grasped in which of the above.

(2) Effects when copying / pasting control parameters of other parts For example, if the melody is almost complete but the song position SP is set in a certain part and the sound of that part is to be improved, DTM In many cases, the method of copying / pasting the control parameters and the like of other parts (parts that have already been convinced) is often used. In this case, first, the user scrolls the display frame to the copy source portion in order to refer to the copy source control parameter, and performs an operation of copying the control parameter set in the portion (the first parameter). Step). Thereafter, the user scrolls the display frame to the position of the song position SP, and pastes the control parameter in the corresponding location (second step). Conventionally, by immersing yourself in editing the music, forgetting whether the song position SP was on the song start side or the song end side when viewed from the current display area EA, the second step is executed. According to this embodiment, the song position SP is viewed from the display area EA on the tune side or the ending side, based on the positional relationship between the song position mark SPM and the virtual knob 210d. It can be easily ascertained which one of these is present, and there is no problem in the execution of the second step.

(3) Effect in cooperation between the track editor screen and the musical editor screen In DTM, the part to be corrected in relation to other parts while comparing the information of each part displayed in the thumbnail on the track editor screen and the relevant part Often, work such as searching for a place to be corrected is performed. In this case, the user sets the song position SP at the correction location specified by referring to the thumbnail display on the track editor screen, and then switches to the musical editor screen to correct the corresponding location. In some cases, it may not be possible to instantly determine whether the song position SP is on the beginning or end of the song as viewed from the display area EA at that time. However, according to the present embodiment, it is possible to easily grasp whether the song position SP is on the song head side or the song end side when viewed from the display area EA, based on the positional relationship between the song position mark SPM and the virtual knob 210d. By moving the virtual knob 210d to the position of the song position mark SPM, the correction location can be easily reached.

Although one embodiment of the present invention has been described above, the following modifications may of course be added to this embodiment.
(1) In the embodiment described above, the song position mark SPM is always displayed on the scroll bar 210c regardless of the relative positional relationship between the song position SP and the display area EA on the time axis, but the song position SP is displayed. The song position mark SPM may be displayed only when it is out of the area EA.

(2) In the above-described embodiment, the song position mark SPM corresponding to the song position SP is displayed on the scroll bar 210c, but the loop start position and end position when the sequence data being edited is played back in a loop are displayed in the musical editor. It may be set on the screen and a mark indicating the position may be displayed on the scroll bar 210c. In addition, the start position and end position of A melody, the start position and end position of B melody, the start position and end position of chorus, or the song to be edited is composed of multiple parts (main vocal part, chorus part, etc.) If there is a mark, a mark indicating the configuration of the entire song in the time axis direction, such as the start position and end position of each part, may be displayed on the scroll bar 210c. That is, the display position of the mark representing the entire composition of the song is calculated and displayed on the scroll bar 210c in the same manner as the song position mark SPM. According to such an aspect, it is possible to easily grasp the relative positional relationship between each constituent element such as A melody and B melody and the display area EA, for example, sequentially in order of A melody, B melody, and rust. When editing the entire song after completion, it is easy to edit other components with reference to already completed components. In addition to the start position and end position of each component of the song, the bar number when the first measure number is set to 1 for every predetermined number of measures (for example, 10 measures) from the beginning of the song to be edited, The sound waveform of the song (the sound waveform of the sound emitted according to the sequence data of the song to be edited) or the lyrics of a song may be displayed on the scroll bar 210c. This is because the measure number, sound waveform, and lyrics also represent the composition of the song to be edited in the time axis direction. In short, auxiliary information (such as a mark or bar number indicating the start position or end position of each component) is displayed on the scroll bar 210c so that the user can understand the composition of the song to be edited in the time axis direction. The display position may be calculated in the same manner as the display position of the song position mark SPM.

(3) In the above-described embodiment, the song position mark SPM corresponding to the song position SP is displayed on the scroll bar 210c. In addition to this, a display area EA is cut out using a display frame having a predetermined length in the pitch axis direction intersecting the time axis, and a virtual knob for moving the display frame along the pitch axis is provided. In addition to being displayed on the display unit 120a together with the scroll bar, in the mark display processing, characters indicating the pitch information and the upper and lower limit pitch names and frequencies of the auxiliary information (pitch name and frequency of each sound or range (soprano, alto, etc.)) Column), the positions of both ends of the virtual knob on the scroll bar correspond to the positions of both ends of the display area EA on the pitch axis, and the position from the position on the pitch axis corresponding to the pitch indicated by the auxiliary information. The distance from the display position of the auxiliary information on the scroll bar to the end of the display area EA on the side closer to In correspondence to the distance to the end of the virtual knob calculates the display position of the auxiliary information, may be caused to execute the process of displaying the auxiliary information on the display position control unit 110. In addition, when displaying auxiliary information indicating a sound range on a scroll bar in the pitch axis direction, different colors may be given to the scroll bar (or display target area EA) for each sound range.

(4) In the above-described embodiment, the present invention is applied to the editing function in the song synthesizer. However, the application target of the present invention is not limited to a singing voice synthesizing apparatus, and may be any editing apparatus that generates sequence data representing a melody from a series of notes inputted as constituting a melody of a song.

(5) In the above embodiment, when the song position SP is on the left side (the beginning of the song) from the display area EA, when the song position SP is in the display area EA, the song position SP is on the right side of the display area EA. The display position SPP of the song position mark SPM was calculated using different formulas for each of the three cases in the (end of music) side. However, the display position SPP of the song position mark SPM may be calculated by dividing the positional relationship between the song position SP and the display area EA more finely. For example, when the song position SP is on the left side (the beginning of the song) from the display area EA, and when the song position SP is on the left side of the midpoint from the beginning of the song to the left end of the display area EA, The display position SPP of the song position mark SPM may be calculated using an expression different from that in the above. The same applies to the case where the song position SP is on the right side of the display area EA.

(6) In the above-described embodiment, a program that causes the control unit 110 to display a sequence data editing screen that clearly shows the features of the present invention is stored in advance in the nonvolatile storage unit 132. It may be distributed by writing in a computer-readable recording medium, or may be distributed by downloading via a telecommunication line such as the Internet. The program distributed in this way is installed in a general computer device such as a personal computer, and the control unit (CPU) of the computer device is operated in accordance with the program, so that the computer device is edited by the editing device of the present invention. It is because it becomes possible to make it function as.
