Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for editing music data (performance information) used for automatic performance in electronic musical instruments, computer music, etc., and particularly to a performance information editing apparatus suitable for editing facial expressions. And a performance information editing program.

[0002]

2. Description of the Related Art If music data is composed only of note information, a mechanical and expressionless performance will result. In order to perform more natural, beautiful, and lively performances, it is necessary to add various musical expressions and musical instrument-likeness as control data, and music data can be edited on electronic musical instruments or computers. It is being appreciated. However, in such an editing system, if it is left to the user which expression is added to which part of the music, the user needs to be familiar with the characteristics of music and musical instruments. Therefore, in order to make the system easily usable by a wide range of users, it is better to automatically perform the part that the system can judge. In addition, it is also important to reflect the user's intention, which part should be given what kind of facial expression.

By the way, in the above-mentioned editing system, music data is displayed on a screen of a computer or the like in a musical score format or a piano roll format, and a musical score or bar corresponding to an event is selected to correspond to the selected one. The method of setting the event to be edited as the editing target is used. Also, when selecting this note, etc., a method is often used in which a two-dimensional area (frame) is specified on the screen by operating the mouse and the note containing the notehead in that area is selected for editing. There is.

[0004]

However, if the above selection operation is erroneous, an appropriate editing result cannot be obtained. For example, in the case of giving a musical expression to a note as shown in FIG. 2, it is assumed that a facial expression range is designated as a selection range A in the same figure. In this case, the note a is not included in the selection range A even within the period of the selection range A. This may be the case where only the notes above a certain range are intentionally selected, but it is more natural to think that the selection of the range has failed due to the selection like the selection range B in FIG. . Also, although it depends on the type of facial expression, it is not possible to expect very good results with facial expression that divides the range by the range as shown in FIG. In other words, the facial expression of the performance is determined by the context before and after the arrangement of the notes, and even if the individual notes are given different facial expressions, an unnatural result is often brought about. For example, when the expression of a guitar is specified by designating in the selection range A of FIG. 2, the vibrato is added as shown in FIG. 4, and the advantage of automatic expression is not very exerted.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible for a performance information editing apparatus to give an appropriate facial expression even if the user makes an error in selecting an event.

The external storage device 5 is a flexible disk device (FDD), a hard disk device (HDD), a magneto-optical disk (MO) device, a CD-ROM device, a digital multipurpose disk (DVD) device, or the like. 5 supplies music data and performance information editing program. In the embodiment, the performance information editing program is installed from the CD-ROM device of the external storage device 5 to the hard disk device, and the performance information editing program is expanded from the hard disk device to the RAM 3 and executed by the CPU 1. In addition, the external storage device 5 is
It is used to store edited music data, and is also used as a database of rule templates and the like that define the rules that indicate the matching conditions and correction details during facial expression processing.

Further, the CPU 1 is, for example, an external storage device 5
The operating system installed in the hard disk drive (HDD) of the above-mentioned computer uses the working area of the RAM 3 to perform normal control. Specifically, for example, the display of the display device 12 is controlled, the data corresponding to the operation of the operator 11 such as the keyboard and the mouse is input, and the display position of the mouse pointer (cursor) on the display device 12 is controlled. The mouse click operation is detected. As a result, the input setting operation and the like by the user is executed by the processing of the so-called graphical user interface (GUI) by displaying the display device 12 and operating the mouse.

The music data in the embodiment is a normal S
It is stored in the MF (standard MIDI file) format, for example, performance data for a plurality of tracks. The performance data is data in which performance event data and generation timing data representing the generation timing thereof are stored in the reproduction order, and the music can be reproduced by using SMF sequencer software or the like.

The process of adding a facial expression to the music data is performed based on the rule selected by the user. This rule represents a rendition style corresponding to a special musical symbol attached to a musical score, and includes, for example, glissando rendition, choking rendition, vibrato rendition, slide up, slide down, and the like. The rule template is prepared for each rule (for each type of playing style), and the matching condition data indicating where the suitable playing style is reflected and the data matching the matching condition And the data of the correction content indicating whether to correct.

Then, the user selects a rule to be reflected in the music data, and a range (selection range) for editing the two-dimensional range of the timing and the pitch is selected with respect to the display in the musical score format or the piano roll format on the screen. When the user specifies, the edit range is determined from the selected range, and the rule template corresponding to the rule is used to automatically edit an appropriate portion (an appropriate event) in which the rule within the edit range is reflected.

FIG. 1 is a flow chart of the main part of a performance information editing program executed by the CPU 1. This process is started when a facial expression giving program is designated in the main flow, and ends when the end is instructed. First, in step S1, the music data to be processed is displayed on the screen of the display device 12 (in a score format or a piano roll format), and in step S2, the rules (contents of facial expressions) to be adapted to the music data are set. Take the action you want. Then, in step S3, the range to be edited by the user (selection range)
Is specified, and if not specified, the process returns to step S2, and if specified, the process proceeds to step S4.

When displaying the music data, in the score format, for example, as shown in FIG. 2, musical notes (event display elements) are displayed on the staff.
Is displayed. In the piano roll format, one note is displayed by a bar (event display element) with the horizontal axis corresponding to time and the vertical axis corresponding to pitch. The vertical axis position of the bar corresponds to the pitch, the head of the bar corresponds to the sound generation timing, and the length of the bar corresponds to the sound length (gate time). In the following description, the case of displaying in score format is described as an example, but in the case of piano roll format, “note” may be read as “bar”.

In step S4, an event corresponding to a note not included in the selection range is detected from the period (selection period) from the start time to the end time of the selection range. The "selection range" is the range of a two-dimensional rectangular frame specified on the screen, and the "selection period" is the range of the timing progression direction (horizontal direction in the musical score format) of this selection range. That is. Further, the “editing range” described later is a range corresponding to all events targeted for the editing process.

When the processing in step S4 is completed, it is determined in step S5 whether or not an event corresponding to a note not included in the specified selection range is detected. If not detected, the process proceeds to step S6 and is detected. If so, the process proceeds to step S7. In step S6, the event corresponding to the note included in the specified selection range is determined as the editing range, and the process proceeds to step S8. In step S7, the event corresponding to the note included in the specified selection range and the detected event (event corresponding to the note not included in the selection range) are determined as the edit half and the process proceeds to step S8.

Then, in step S8, the edit portion is determined for each rule from the events included in the edit range, the edit portion is edited with the edit content corresponding to the rule, and the process proceeds to step S9. In this editing process, control data is added to the event corresponding to the music data, and a symbol corresponding to facial expression is displayed on the screen.
In step S9, it is determined whether or not the end of the facial expression imparting program is designated. If the end is not instructed, the process returns to step S2, and if the end is instructed, the process is ended.

The details of the editing process are described in Japanese Patent Laid-Open No. 2001-2001.
159892 (Japanese Patent Application No. 2000-077340).

The expression expression of a guitar will be described as an example of the expression expression rule as follows. a) If the note is longer than a certain amount, vibrato is added. b) Add slide-up at the beginning of the phrase. c) When consecutive notes have a certain length or more and a pitch difference of a certain amount or more, a slide down is added between the notes. d) When a note is a note of a certain length or more and both of the notes before and after the note have low pitches, choking up is added to the note.

Based on the above rules, when the facial expression is applied in the selection range A as shown in FIG. 2, the result as shown in FIG. 3 is obtained. That is, even if the selection range A is erroneously designated as shown in FIG. 2, only the vibrato is not added as in the conventional FIG. 4, but the facial expression processing including the event corresponding to the note a is performed. The result of doing. As shown in FIG. 3, slide up, slide down and chalking up are also added. Needless to say, the same applies when the selection range B as shown in FIG. 5 is designated.

Depending on the type of facial expression, it may be effective to add individual facial expressions to the discrete events. In the case of music data corresponding to a piano staff, the MIDI data (performance data) corresponding to the bass clef (for the left clef of the clef) and the treble clef (for the clef of the right hand) of the grand staff are 1 When the data is MIDI data of a track, it is interpreted that the expression is intended to be applied only to the selected range (notes that may be played with the right hand). Therefore, in contrast to the first selection function which edits all the notes within the selection period of the selection range including the selected note, the second selection function which edits only the notes selected in the selection range
Prepare a selection function of, and record as a table which of the first and second selection functions to use according to the rule,
The selection function corresponding to the selected rule is determined by referring to the table, and the selected selection function is set as an edit target.

The display format of the music data may be a piano roll format in addition to the musical score format of the embodiment. Note that the first one bar of FIG. 2 is shown in FIG. 6 in the piano roll format, and the two-dimensional selection range A corresponding to the pitch and timing is shown.
When is specified, the same processing as that in the musical score format can be performed.

The display format, such as an event list format in which event data is simply arranged in the order of timing, displays note events along with time progression.
Any note event may be selected from among the plurality of note events as long as the note event to be edited for expression expression can be arbitrarily selected (in an irregular manner) instead of the time progression order.

Although the above-described embodiment is composed of a personal computer and software, the present invention can also be applied to an electronic musical instrument. In that case, the performance information editing program and the rule template may be recorded in the ROM 2.

Since the communication interface 10 is connected to the server computer via the communication network 15 as described above, when the performance information editing program and various data are not stored in the hard disk device,
You may make it download a performance information edit program and various data from a server computer. In this case, the terminal device (personal computer) of this embodiment, which serves as a client, transmits a command requesting the download of the control program and various data to the server computer via the communication interface 10 and the communication network 15. The server computer receives this command, distributes the requested program and various data to the terminal device of the present embodiment via the communication network 30, and the terminal device of the present embodiment sends these programs via the communication interface 10. The download is completed by receiving the program and various data and storing them in the hard disk.
