Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical score editing system that processes input musical score information and draws and edits it on a screen, and in particular, automatically assigns notes to a set staff. The present invention relates to a musical score editing system for creating musical composition information.

[Conventional technology]

Heretofore, as a device of this type, there has been proposed a music composition preparation device described in Japanese Patent Application Laid-Open No. 63-57234.

Specifically, using a personal computer and a high-resolution display started with a highly versatile OS (for example, MS-DOS manufactured by Microsoft), a personal computer and a high-resolution display are used to draw on a screen in accordance with music information input instructed by a pointing device or the like. And assigns the information to another composition information processing system via a storage medium such as a floppy disk or on-line, and transfers the final composition information to the composition creation device ( For example, a high-definition copy as a printed matter is created by outputting to a computer typesetting system. Note that the resolution that can be expressed by the personal computer and the output resolution on the composition creation device are greatly affected by hardware limitations.For example, if the resolution on the editing system is 300 DPI, the difference is about 700 to 900 DPI. This is usually the case.

[Problems to be solved by the invention]

By the way, the musical score information handled by the musical score composition creating apparatus mainly has a relation between a note and a staff.
However, a score is defined as a note and its associated modifiers (eg, slurs, mesoforte (m
In general, not only musical notation of symphony music composed of f) etc. but also musical notation accompanied by lyrics is handled.

However, in a conventional system, a note instruction and a lyrics input process are performed by an instruction means such as a pointing device.
Since the processing was performed character by character, the lyric input positions varied (especially when lyrics were input in a plurality of stages), which greatly reduced print quality and necessitated complicated input instructions. However, there is a problem that the visual operation load of the user is large. In addition, in this type of composition creation system, complicated layout data which cannot be processed by note layout as required by commercially available music software is required. That is, the pitch of each note is not fixed, and the assigned pitch varies depending on the note font size to be printed. Therefore, in the layout process, it is necessary to consider the size of the printing plate, the size of the note font to be adopted, the musical notation symbols (tie slurs, crescendos, etc.), etc., and are usually left to the manual work by a skilled person. There are many parts.

The present invention has been made in order to solve the above problems, and by calculating the assigned position of each note to be arranged while analyzing the sound length of the assigned note,
It is an object of the present invention to obtain a musical score editing system capable of automatically editing a note input at an optimum note assignment position with a simple operation.

[Means for solving the problem]

A musical score editing system according to the present invention includes a calculating means for analyzing a note length and an attached symbol attached to an arbitrary position on a staff image and calculating a note assignment position by calculating a note length, and based on a calculation result of the calculating means. Automatic assigning means for automatically reassigning each note and an attached symbol attached to each note.

FIGS. 3 and 4 are schematic diagrams for explaining the note arrangement position calculation processing by the calculation means 1e shown in FIG. 1, and assume that, for example, each note is assigned to a staff notation.

In these figures, t indicates the time axis, and the length of the sound of each note (defined by the note) allocated from the origin of the time axis to the beginning of the staff, that is, the total of the note value, is taken as a staff. This corresponds to the time axis t. C1 to C5 are margin areas (fixed values that are always required), and these margin areas C1
CC5 is removed from the staff length, and this is defined as staff length l. t _{1 to} t ₄ are link times, which correspond to the times to which the notes belong.

 First, the process of temporarily determining the note interval will be described.

When the link times t _{1 to} t _n are set, the minimum value t ₀ is defined. Assuming that the distances corresponding to the intervals between the link times t _{1 to} t ₄ are L _{1 to} L ₄ , the following equation (1) holds.

L ₁ + L ₂ + L ₃ + ... + L _N = 1 (1) Therefore, calculation unit 1e, the minimum value each distance multiplied by the constant α for converting the time interval to the distance interval on the ratio of each link time t ₁ ~t ₄ for the t ₀ to the shortest note spacing L ₀ L ₁
Regarded as corresponding to the ratio of ~L _N, defines the shortest note spacing L ₀ from the following second equation (2).

Accordingly, the distance L ₁ ~L _N as defined above equation (1) is calculated from the first (2), automatic editing means 1d on the basis of the auto-computed respective distances L ₁ ~L _N etc. Rearranges each note to optimize the allocation position. At this time, it is determined whether or not the overlap as shown in FIG. 5 has occurred. If the overlap has occurred, the assigned position is forcibly shifted rightward to a position where the note does not overlap. Go.

As a result, for example, when a note that protrudes from a staff is generated, the automatic editing of the note is completed by calculating a stuffing amount that converges the protruding portion and redistributing it.

The automatic note editing process in the musical score editing system according to the present invention will be described below with reference to the flowchart shown in FIG.

FIG. 6 is a flowchart for explaining an example of an automatic musical note editing process in the musical score editing system according to the present invention. Note that (1) to (6) indicate each step.

First, when "edit" of the menu 21 is instructed by the pointing device 2a, this flow starts, and first,
It is determined whether or not the editing target is a column (in the case of a musical score in which the staff is divided into parts) (1), and if YES, a time axis of the column total is created (2), and step (4) and thereafter. Proceed to.

On the other hand, if the determination in step (1) is NO, a time axis is created (3), and the calculating means 1e executes a process of tentatively determining a note interval (4), and executes an overlap confirmation process (5). A protruding confirmation process is executed (6), and each note is automatically edited.

Note that the automatic editing may be performed in parallel with the note assignment process, or the previously created score layout information may be read from the score layout data storage unit 7 and the automatic editing may be performed in response to the layout change. good.

Further, in the above-described embodiment, the case has been described where the arithmetic processing is performed with the constant α being regarded as fixed.

〔The invention's effect〕

As described above, the present invention analyzes the note length and the attached symbol attached at an arbitrary position on the staff image and calculates the assigned position of each note by analyzing the pitch.
Automatic assignment means for automatically reassigning each note and an attached symbol attached to each note based on the operation result of this operation means is provided. It can be assigned at intervals and anyone can easily assign notes to musically correct positions.

Even if each note is roughly assigned to the staff in the note assignment process, it is always automatically edited to the optimal note arrangement position, so the assignment operation burden of the note input person is eased and efficient. This produces effects such as the ability to assign and correct notes.
