DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument editing apparatus for editing the tone of a musical tone formed by an electronic musical instrument.

[0002]

2. Description of the Related Art A conventional electronic musical instrument synthesizes musical tones with not so many parameters, so that it is possible to directly edit an electronic musical instrument having a keyboard or the like. In this case, the tone of the musical tone being edited could be confirmed immediately by playing the keyboard.

However, in recent electronic musical instruments, a tone is edited using a dedicated editing device (computer) in order to synthesize a musical tone using an extremely large number of parameters.

[0004]

In this case, when the tone being edited is to be produced, when the electronic musical instrument is far from the editing device, the editing must be interrupted and the keyboard or the like must be operated, which is bothersome. Was. Further, even when the editing device and the electronic musical instrument are integrated, it is necessary to temporarily stop the editing operation to operate the keyboard or the like. Further, in computer music using a sound source and a sequencer software of a computer, the keyboard itself does not exist, and in some cases, even if the timbre is edited, the sound cannot be reproduced on a trial basis.

For this reason, it has been proposed that a graphic such as a keyboard is displayed on a screen, and when the graphic is designated (clicked) with a pointing device such as a mouse, the tone being edited is pronounced. The volume and the sounding time could not be set, and the change in the tone due to the difference in the volume could not be confirmed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic musical instrument editing apparatus that allows a user to test a musical tone at an intended volume.

[0007]

According to the present invention, there is provided a display screen, a designation means for designating an arbitrary position on the display screen, an operation force detection means for detecting an operation force of the designation means, and a tone color of a musical tone. A tone editing means for displaying a parameter for controlling the parameter on the display screen and changing a parameter displayed at the position designated by the designation means, and detecting that the designation means has designated a specific position on the display screen. A specific position designation detecting unit, a sounding unit that emits a musical tone of a parameter displayed on a display screen when the specific position designation detecting unit detects the designation of the specific position, and the specific position designation detecting unit is located at the specific position. Level control means for controlling the sounding level based on the operation force of the designation means detected by the operation force detection means when the designation is detected. That.

[0008]

According to the present invention, the parameters of the musical tone to be edited are displayed on the display screen, and the parameters specified by the specifying means are changed. Further, when the specific position is specified by the specific position specifying means, the musical tone is generated. The specific position is, for example, an icon. The level (volume) at the time of sound generation is controlled according to the operating force of the specifying means detected by the operating force detecting means. This makes it easy to test-listen to the musical tone being edited, and allows the user to produce a musical tone at a desired volume.

FIG. 1 is a block diagram of an electronic musical instrument incorporating an editing device according to an embodiment of the present invention. This electronic musical instrument includes a musical sound synthesizing circuit 18 and a MIDI interface 17, and synthesizes musical tones based on performance information input from the MIDI interface 17, and the electronic musical instrument itself does not include a performance device such as a keyboard. . Further, a display 16 is provided, and the timbre parameters of the musical tone can be displayed and edited on this display.

This electronic musical instrument is controlled by the CPU 10. The CPU 10 has a ROM 12 and an R
The AM 13, the display interface 14, the sensor interface 15, the MIDI interface 17, and the tone synthesis circuit 18 are connected.

The ROM 12 stores an apparatus program and various timbre data shown in a flowchart described later. In the RAM 13, a register for temporarily storing performance information input from the MIDI interface and an area for storing edited timbre data are set.

The display interface 14 and the sensor interface 15 are connected to a display 16. The display 16 includes a large liquid crystal panel 16a and a touch panel 16b provided on the surface thereof. The display interface 14 is connected to a liquid crystal panel 16a, and the sensor interface is connected to a touch panel 16b.

A MIDI playing device such as a keyboard is connected to the MIDI interface 17.

The MIDI performance device includes a performance operation unit such as a keyboard and a control unit.
Generate DI data. This MIDI data is MIDI
The data is input to the electronic musical instrument via the interface 17.

The voice synthesizing circuit 18 synthesizes a tone signal based on the performance data input from the CPU 10. The synthesized tone signal is input to the sound system 19. The sound system 19 amplifies and outputs the input tone signal.

FIG. 2 shows a schematic configuration diagram of the touch panel 16b. FIG. 3 is a schematic configuration diagram of an electronic pen 20 which is a pointing device used in the touch panel 16b. The touch panel 16b is formed by pattern-forming 640 vertical lines and 480 horizontal lines on both sides of a transparent resin panel. The vertical line defines the X coordinate on the screen, and is an X coordinate detection line for detecting the X coordinate of the position where the electronic pen 20 has touched.

The horizontal line defines the Y coordinate on the screen.
This is a Y coordinate detection line that detects the Y coordinate of the position where the electronic pen 20 has touched. On the other hand, the electronic pen 20 includes a pen shaft 21 which is a conductor. The pen shaft 21 is urged in a direction to protrude from the pen body 20, but the touch panel 16b
To move into the pen body 20. A ferrite core 22 is attached to the upper end of the pen shaft 21. Around the ferrite core 22, a coil 23 is fixedly mounted on the pen body. The resonance frequency of the coil 23 fluctuates due to the vertical movement of the ferrite core 22.

When a magnetic field is applied to the surface of the touch panel 16b and the electronic pen 20 approaches the touch panel 16b, a high frequency is generated in the coil 23 by the magnetic field. Electronic pen 2
When 0 (pen shaft 21) is brought into contact with the touch panel, the X coordinate detection line passing through the position where the pen shaft 21 is in contact,
A weak high-frequency current is applied to the Y coordinate detection line. The sensor interface 15 constantly scans the X coordinate detection line and the Y coordinate detection line. The sensor interface 15 detects that the electronic pen 20 has touched (clicked) the coordinates of the coordinate detection line by detecting the high-frequency current, and sends the coordinates to the CPU 10. Also, by detecting the detected high frequency, the strength of pressing the electronic pen 20 against the touch panel 16b is detected. That is, when the electronic pen 20 is strongly pressed against the touch panel 16b, the pen shaft 21 enters into the main body, and the ferrite core 22 attached to the upper end also enters into the coil 23. As a result, the resonance frequency becomes lower. Therefore, the operating force of the electronic pen 20 can be detected by monitoring the detected frequency.

In this way, the coordinates on the display 16 designated (clicked) by the tip of the electronic pen 20 can be detected by the touch panel 16b, and the operating force can be detected. Such a technique is disclosed in, for example, Japanese Patent Application Laid-Open No. 64-53222.

FIG. 4 shows a display 16 (liquid crystal display 16).
It is a figure showing the example of a display of a). This figure is a display example in the timbre edit mode. The screen is of a window type, and the tone color parameters of the selected musical tone are displayed in a list in windows 30 and 31. By specifying parameters using the electronic pen 20 and changing these parameters using the electronic pen 20 or other input operators, the timbre can be edited. In the edit mode, a plurality of timbres can be edited in parallel, and windows 30 and 31 of each timbre are partially overlapped and displayed.
In this drawing, the timbres of PIANO1 and FLUTE are edited in parallel. The parameters of the tone displayed on the front can be changed.

A sound icon 32 is displayed in the upper right part of the screen. There are two types of sounding icons 32: a speaker graphic (speaker-type icon: FIG. 5A) and a keyboard graphic (keyboard-type icon: FIG. 5B) shown in FIGS. 5A and 5B. In FIG. 4, a keyboard icon is displayed.) When the sounding icon 32 is designated (clicked) with the electronic pen 20, the tone being edited is sounded. When the sound icon 32 is specified twice (double-clicked) continuously with the electronic pen 20, a window for setting parameters for test sound generation is displayed on the display 16 as shown in FIG.

In the figure, a TYPE area is an area for selecting which of a speaker type icon and a keyboard type icon is to be displayed. SPEAKER, KEYBOARD
Are selected in each of the columns in which a circle is displayed in the circle at the left end. In addition, a speaker type icon (SPEAKE
R), the pitch (PITC
H) can be set. To set the pitch, the user enters a new pitch by adding or subtracting after specifying a numerical value ("A3" is displayed in the figure) with the electronic pen 20. In addition, a keyboard icon (KEYBOA)
When (RD) is designated, the shift amount (NOTE SHIFT) of the pitch (basically C3 to C4) designated on the keyboard can be set. In this case as well, the field of the numerical value (+12) is designated by the electronic edition 20 to increase or decrease or input a new value.

The NOTE OFF area is an area for designating when the generated musical tone is to be muted. There are three options: release (when the electronic pen 20 is released from the icon), after a predetermined time, or when re-clicked (sound generation starts with the first click and silences with the second click). When a time after a predetermined time is selected, the time can be set. In the figure, it is set to 1000 ms.

Further, the VELOCITY area is an area for setting a level of a musical sound to be generated. There are three options: a predetermined value, a pen, and an operator. The predetermined value is given by velocity data (0 to 127) and can be set by the user. In the figure, it is set to 63. When the pen is selected, the level is controlled by velocity data generated based on the operation amount data of the electronic pen 20. When an operator is selected, the electronic musical instrument or MIDI interface 17 is selected.
The velocity data is generated on the basis of the operation amount data of another operation element input via the.

In FIG. 5, NOTE OFF indicates a click at the time of re-clicking, and VELOCITY indicates that a pen is selected.

FIG. 7 is a flowchart showing the operation of the electronic musical instrument. When the power of the electronic musical instrument is turned on, first, an initialization operation is executed (n1). The initialization operation includes clearing a register, transmitting preset tone color data to the tone synthesis circuit 18, and the like. Thereafter, a click (input) by the electronic pen 20 is detected (n2).

When an input is detected, it is determined whether or not the coordinate value is on the sounding icon (n3).

If it is on the sounding icon, it is determined whether the tone color parameter is currently being displayed (in a window) (n
4). If the tone parameters are displayed in a window,
It is determined whether or not the currently displayed icon is a keyboard icon (n5). If it is a keyboard icon, the key of the keyboard at the clicked position is detected, and a value obtained by adding the NOTE SHIFT to the key code of this key is set in the key code register KC (n6). Next, it is set in the key velocity register KV based on the set contents.

That is, selected one of data generated based on the operation amount data of the electronic pen, data generated based on the operation amount data of the operating element, and a predetermined value is set (n7: FIG. 6). According to this, the electronic pen 20 is selected.) The sounding event data, KC, KV, and other data are sent to the tone synthesis circuit 18, and when sound is muted, sounding / silence processing is executed by sending out silence data (n8).

If the displayed icon is a speaker type icon, a preset pitch (PITCH) is set in KC (n9), and the pitch is set in the key velocity register KV based on the set contents. Set (n10). Thereafter, the operation of n8 is executed.

On the other hand, if the content displayed at the position where the pen is operated is not a sounding icon, a corresponding process (other window process) is executed (n13). The contents include a change in parameter selection and a change in parameter value.

Thereafter, display processing is executed to reflect the processing contents on the display (n11), and other tone processing such as forming a tone signal based on performance data input from the outside via the MIDI interface (n12). Execute

Hereinafter, the operation of n2 or less is repeatedly performed.

Although the electronic pen 20 is used as a pointing device in this embodiment, a mouse may be used. In this case, the click switch of the mouse has an operation pressure detection function.

Although the control flowchart is shown in a procedure-oriented manner, a program using an object-oriented method may be executed.

In this embodiment, one of the keyboard-type icon and the speaker-type icon is displayed on the screen. However, both may be displayed, and the musical tone may be produced in the specified method.

A mouse or display for editing musical sounds may be separated from the main body of the controller, so that a general-purpose configuration can be used which can be shared by a plurality of electronic musical instruments.

It is also possible to produce a plurality of tones simultaneously.
