BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance data editing device and a recording medium recording a performance data editing program, and in particular, separation (division) and synthesis of (accompaniment) style sequence data corresponding to song data such as a melody. The present invention relates to a performance data editing device and a recording medium having a performance data editing program recorded therein for supporting editing of performance data so as to facilitate editing processing of the performance data.

[0002]

2. Description of the Related Art Conventionally, there has been known an automatic performance device for performing automatic accompaniment using (accompaniment) style sequence data in order to perform accompaniment corresponding to song (sequence) data as performance information. In such an automatic performance device, the (accompaniment) style sequence data created by the user is used to specify the pronunciation timing data and the pronunciation style so that the desired accompaniment style is played (pronounced) at a desired timing. Style data (including,
Section data) is arranged in chronological order.

In the conventional automatic performance device described above, when the desired style sequence data is edited, by directly changing the numerical data or the character data expressed by a predetermined character string which constitutes the existing style sequence data. It is known to be configured to obtain desired style sequence data.

Further, in the conventional automatic performance device, song (sequence) data (= timing data for each event representing the pronunciation of a musical sound and data in which event data is arranged in time series) is displayed on the screen and a mouse or the like is displayed. There is also known a device which can perform editing such as separation (division) and composition of song (sequence) data by operating the input / output device.

That is, in the editing function of the conventional automatic performance device, a desired position of the displayed song (sequence) data is designated, and the song (sequence) data is edited at the data position. More specifically, when performing division processing of song (sequence) data, specify the position to be divided with a mouse cursor or the like on the screen of the display, and divide the song (sequence) data at the specified position. It was.

[0006]

Now, let us consider a case where the editing method in the conventional song data editing apparatus is simply applied to the editing of style sequence data.

For example, when the designated division position is a position in the middle of the performance of the style data, the style data that originally forms the style sequence data does not exist at the designated position in the style sequence data. By inserting the data for delimiting the style data at the position, the accompaniment ends at the insertion position, and thereafter, no accompaniment is performed until the pronunciation start data of the next style data is read in the style sequence data. There was a problem that it would not be performed.

Further, in the above-mentioned conventional performance data editing apparatus, the style sequence data is edited by inputting numerical values in order to avoid the above problems, and there is a problem that the editing operation is troublesome. Further, it is difficult for the performance data editing apparatus for inputting numerical values as described above to edit while comparing the style sequence data with the corresponding song data, and the style sequence data is created or edited to match the song data. The work was very cumbersome. Especially for beginners, this point makes the work difficult.

Therefore, a first object of the present invention is to accurately obtain a desired style sequence data by a simple operation without causing a defect such as a section in which no accompaniment is performed even when the style sequence data is edited. (EN) Provided are a performance data editing device and a recording medium having a performance data editing program recorded therein.

A second object of the present invention is to provide a performance data editing apparatus and a recording medium having a performance data editing program recorded therein, in which the editing operation of style sequence data is simple. Further, a third object of the present invention is to provide a performance data editing device capable of performing editing work while comparing song (sequence) data and style sequence data, and a recording medium recording the performance data editing program. It is in.

In the determination in step S32, if an instruction to execute the separation process is given (step S32;
Yes), as shown in FIG. 10, the timing data corresponding to the separation position SP, the style end data indicating the end of the first half of the separated style sequence data, and the leading pronunciation style and section of the latter half of the style sequence data are displayed. The same style number data SN and the same section data SC as the style data of the first half portion to be expressed are inserted at the specified cutoff position (step S33).

Then, the controller 11 adds the two separated style data to the style information display area 34 with a new section name (both "Main B" in FIG. 11) in the style information display area 34, as shown in FIG. Blocks are displayed as edit target marks (step S34), and the process proceeds to step S6.

(3.1.4) Compositing Process Next, the controller 11 includes the keyboard unit 12,
Via the keyboard interface 13 and the bus 14, or the mouse 15 and the mouse interface 1
6 and the bus 14 are used to determine whether or not style sequence data synthesis processing is designated (step S).
6).

Specifically, as shown in the upper part of FIG. 15, the synthesis processing designation is made by clicking the "bond (adhesive)" mark button in the button with the mouse.

If it is determined in step S6 that the synthesis processing of style sequence data has not been designated (step S6; No), the process proceeds to step S8. In the determination in step S6, when the synthesis processing of style sequence data is designated (step S6; Yes), the processing shifts to the synthesis processing routine of style sequence data (step S7).

(3.1.4.1) Composition Processing Routine FIG. 12 shows a composition processing routine of style sequence data. The controller 11 shifts to the synthesis position designation processing, and causes the operator to designate the synthesis position of the style sequence data (step S41).

More specifically, as shown in FIG. 14, the operator designates the combining position SY on the screen of the display 24 via the keyboard unit 12 or the mouse 15.

Next, the controller 11 determines whether or not an instruction to execute the combination processing of the style sequence data corresponding to the combination position SY is given by the operator via the keyboard unit 12 or the mouse 15 (step S42). .

If it is determined in step S42 that the instruction to execute the combining process is not given (step S42).
42; No), and when the instruction to execute the combining process is given in the determination in step S42 that shifts the process to step S8 (see FIG. 3) (step S42; Ye
s), as shown in FIG. 13, style end data SEN (= timing data TD2P and style end data SendP) indicating the end timing of the style data on the front side of the position where synthesis is instructed, and the style number of the style data on the rear side. The data SNP and the section data SCP are deleted (step S43).

Then, the controller 11 uses the style sequence data obtained by the synthesis as shown in FIG.
As shown in, the section name (“Main B” in FIG. 15) is displayed in a block as a new edit target mark in the style information display area 34 (step S44), and the process proceeds to step S8.

Then, in accordance with instructions (not shown) such as start and end of reproduction of the automatic performance, sound generation processing of the automatic performance is performed based on the song data and the created style sequence data (step S8). This automatic performance sound generation processing is music sound generation based on conventionally known MIDI data, and a detailed description thereof will be omitted here.

Next, as shown in FIG. 4, the style and section of the desired block of the style sequence data displayed on the screen are changed (step S9). Specifically, the mouse 15 is operated to move the cursor to a block in the desired style sequence data on the screen.

After that, when a button (not shown) of the mouse 15 is clicked, a list box listing the styles and section names shown in FIG. 14 is displayed. Then, by selecting the desired section name in the displayed list box with the mouse 15, the section set in the block is changed to the selected section.

The same applies to changing the style. In the figure, when "select style" in the list is selected using the mouse 15, a dialog box showing a list of styles is displayed on the screen. Then, the user uses the mouse 15 to select the desired changed style name from the displayed list.

With the above processing, it is possible to change the setting of the style and section of each block s of the style sequence data. Subsequently, other processing such as selection of song data is performed (step S10), and it is determined whether or not an instruction to turn off the power is given (step S11).

In the determination in step S11, if the instruction to turn off the power is not issued (step S11; No), the process proceeds to step S2, and the processes from step S2 to step S11 are similarly repeated. It will be. In the determination in step S11, if an instruction is issued to turn off the power (step S11; Y
es), the power is turned off, and the process ends.

As described above, according to the first embodiment, inconveniences such as the occurrence of a section in which the accompaniment is not played occur in the style sequence data created after the style data is separated and synthesized, The desired style sequence data can be accurately created by a simple operation.

Further, since the style sequence data is displayed in the style information display area along with the section name as a block to be edited as a block, the input / output device such as a mouse is used to visually perform the edit processing such as separation and composition. This can be done and the editing operation can be facilitated.

Further, by displaying the style sequence data on the display screen of the display 24 simultaneously with the display of the song data, the user can try to associate the song data with the style sequence data. It is possible to read the flow of style sequence data and perform more advanced editing work.
