DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for selecting arbitrary waveform data from waveform storage means for storing sampling waveform data of musical tones and the like, displaying the selected waveform data on a display screen, and cutting a part or all of the waveform data. The present invention relates to a waveform editing apparatus that edits arbitrary waveform data by an operation such as copy and paste.

[0002]

2. Description of the Related Art In a waveform editing apparatus capable of editing sampled waveform data such as musical tones on a display screen, an arbitrary area (Region: Region) on the display screen is designated, and the designated area is cut. The data is stored in the buffer or the area is copied to the buffer, and can be pasted to another area or other waveform data, or the sound of the area can be generated.

In a conventional waveform editing apparatus, the above functions are realized by dedicated software for waveform editing or by the functions of the waveform editing apparatus itself. The waveform data is used to be read out as a musical tone waveform during performance.) The overall start, end address, loop start and end addresses, release start and end addresses,
Input means is provided for setting the start and end addresses of the region.

[0004]

However, the above-mentioned conventional waveform editing apparatus designates basic functions for editing such as cut, copy, paste, etc., and specifies the start and end addresses of the entire waveform, loop, release, region and the like. However, these functions were not enough to improve operability. For example, when editing a certain waveform, sometimes it is necessary to find an appropriate position in terms of hearing and set its address as the start or end address of a loop or region. In this case, it is not possible to easily extract an address that can be recognized as an appropriate position in terms of hearing and set it as a start or end address. Further, since the width of the horizontal axis of the display screen is limited, there is usually a waveform portion which does not appear on the display screen, but it is not easy to bring an arbitrary address to the display screen.

[0005] It is an object of the present invention to provide a waveform editing apparatus capable of improving operability at the time of editing a waveform and improving editing efficiency.

It is another object of the present invention to provide a waveform editing apparatus which facilitates optimal editing in accordance with the audibility of an operator when editing waveform data.

[0007]

According to the present invention, there is provided a waveform editing apparatus comprising: a waveform storage means for storing waveform data of musical tones and the like; and a display means for displaying arbitrary waveform data stored in the waveform storage means. Prepare. The display means further displays an address at a specific position (start address, end address of each portion) of the waveform data as a parameter setting address, and displays an address of an arbitrary position of the display portion of the waveform data as a monitor address. I do. As a target of the waveform data stored in the waveform storage means, a sound source of a natural instrument such as a piano is usually selected, and sound data of each pitch is collected from the sound source, and waveform data sampled at an appropriate frequency is used. You. When a plurality of waveform data are stored in the waveform storage means, the waveform data displayed on the display means is:
Arbitrary data is selected from the plurality of waveform data. The selection of the waveform data can be made directly by a selection switch on the display panel or the like, but it is also possible to select by external MIDI data by connecting a MIDI interface as shown in the embodiment described later. It is.

A monitor address for specifying an arbitrary position of the waveform data displayed on the display means can be changed by a monitor address specifying operator. The monitor address is displayed together with the waveform data on the display screen. As a display mode, the address itself can be directly displayed or displayed with a cursor.

In the waveform editing apparatus according to the present invention, in addition to the above configuration, when the position specified by the monitor address changes on the display screen, the waveform data corresponding to the change is read out from the waveform storage means to generate a sound. It is provided with sound generating means. Further, when the designated position changes, a display control means for moving the waveform data displayed in accordance with the change is provided. Further, there is provided means for making the parameter setting address equal to the monitor address designated by the monitor address designation operator. Therefore, when this means is activated, a monitor address representing an arbitrary position of the waveform data on the display screen is set as an arbitrary parameter setting address such as the start and end addresses of the waveform and the start and end addresses of the loop. Is done.

Further, the waveform editing apparatus according to the present invention, together with the waveform storage means, the display means, and the display control means, sets the monitor address designated by the monitor address designating operator on the parameter setting displayed on the display means. A monitor address changing means for making the address equal to the address is provided. Therefore, by activating the monitor address changing means, various start and end addresses are immediately set to the monitor address. Since the display portion of the waveform data is controlled so that the position of the monitor address is always displayed on the display means, when the monitor address becomes equal to the parameter setting address, the waveform data at the position of the parameter setting address is displayed at that moment. Will be displayed.

In the waveform editing apparatus according to the present invention,
Further, when there are a plurality of parameter setting addresses displayed on the display means (when a plurality of start addresses and end addresses are displayed), any one of these parameter setting addresses is designated by a cursor or the like. A parameter setting address selecting means for selecting,
Further, the monitor address changing means is configured to make the monitor address equal to the changed parameter setting address when the selection destination of the parameter setting address is changed. Note that the change of the parameter setting address includes a case where the selection destination of the parameter setting address is changed and a case where the parameter setting address itself selected by the parameter setting address selecting means is changed by a numerical key or the like.

[0012]

In the waveform editing apparatus according to the present invention, when the monitor address of the waveform data displayed on the display means is changed by the monitor address designating operator, the waveform data corresponding to the change is read and sounded. The operation is stopped when a proper position comes to the sense of hearing. If the parameter setting address changing means is activated at that stage, the parameter setting address can be made equal to the monitor address at the stopped position. For example, when the parameter setting address is the end address of the loop, when the change of the monitor address is stopped at a position that is considered to be appropriate from the viewpoint of hearing, and the parameter setting address changing means is started, the address of the stop position is immediately changed to the end address of the loop. Is set as The same applies to the case where the parameter setting address is the end address of a predetermined region and the case where the parameter setting address is the end address of the entire waveform.

Further, in the configuration having a monitor address changing means for making the monitor address equal to the parameter setting address instead of the parameter setting address changing means, when the monitor address changing means is activated, the monitor address at that time is set to the parameter setting address. Change it to be equal to the address. As a result, since the monitor address is changed, the position of the display waveform data is changed in accordance with the change so that the position of the monitor address is on the display screen.

When a plurality of parameter setting addresses are displayed, for example, when a waveform start address, a waveform end address, a loop start address, a loop end address, etc. are displayed, a parameter selection means such as a cursor selects one of them. Can be selected, but when the selected parameter setting address is changed, for example, when the selected parameter setting address is changed from a start address to an end address, By activating the monitor address changing means, the monitor address is changed to be equal to the changed parameter setting address.

In this way, by loading an address considered to be an appropriate position in terms of hearing to the parameter setting address, the address of the waveform data designated by the monitor address is immediately set as the parameter setting address, or conversely. The parameter setting address can be loaded to the monitor address, and the position of the parameter setting address can be immediately displayed on the display means.

FIG. 2 is a schematic view of the operation panel 9 of the electronic musical instrument.

A display 8 is arranged substantially at the center of the operation panel 9, and a shuttle / jog dial 20, a numerical input switch group 21 and a cursor key 22 are arranged on the right side of the display 8, and on the left side of the display 8. Is provided with an L mode designation switch group (described later) 23, and below the display 8,
Shift switch 24 and function switch 25
Is arranged.

The shuttle / jog dial 20 has an inner rotary knob (jog) and an outer rotary knob (shuttle) arranged on the same axis. By rotating one or both dials, the shuttle / jog dial 20 will be described later. The monitor address can be changed continuously. The numerical input switch group 21 includes ten-keys, and is used to directly change the values of various addresses displayed on the display 8 with the keys. The cursor key 22 is used to move a cursor displayed on the display 8. The type of various parameter setting addresses can be selected by moving the cursor. The L mode designation switch group 23 is used to designate a rough operation mode of the electronic musical instrument. Rough operation modes include a recording processing mode used as a sampler,
There are a waveform edit mode used as an editor, a waveform assignment mode for deciding to which range the stored waveform data is assigned when the entire range is divided into a plurality of ranges, and another mode. Function switch 25
Has a switch function displayed below the display 8.
The shift switch 24 is a switch for instructing the shift function of the function switch 25.

As described above, this electronic musical instrument has the recording processing mode functioning as a sampler, the waveform edit mode functioning as an editor, and the waveform assigning mode for assigning a waveform to a sound range. Although the display screen of the display 8 and the function of the function switch 25 are changed, the waveform edit mode according to the present invention is further divided into four stages (S mode), and the display screen is changed according to each mode. And the function of the function switch changes.

The contents of the four-stage S mode will be described below.

FIG. 3 shows that when the waveform edit mode is selected on the L mode selection screen, four S mode screens can be selected, and a jump menu screen can be pop-up displayed from the three mode screens. It indicates that there is.

The S mode includes a quick setting mode, a process setting mode, a lube setting mode, and a parameter setting mode.

The main functions in each setting mode are as follows.

(1) Quick setting mode Only a minimum editing function is provided for a user who does not want to edit waveform data in detail.

(2) Process setting mode The region of the waveform data to be edited is referred to as a region here, and an edit operation such as cut, copy, paste (paste) is performed on the region (hereinafter, this edit operation). Is called a job). However, it is possible to have a plurality of region areas.

(3) Loop setting mode The sustain area of the waveform data is reproduced by repeating the loop data, and its main function is to make fine settings for this loop.

(4) Parameter setting mode A setting address of a specific position of the waveform data displayed on the display screen, for example, a waveform start address, a loop start address, etc. is called a parameter setting address here. The main function is to set the type.

It should be noted that the jump menu screen which is displayed as a pop-up is displayed when a specific switch is operated under specific conditions in the quick setting mode, the process setting mode, and the loop setting mode.

FIG. 4 shows a quick setting mode screen.

In the figure, a region R1 displays general items including attributes and the like relating to the currently selected waveform data. A region R2 displays a part or all of the selected waveform data on the horizontal axis and the time axis. As a graphic. In a region R3, a monitor address for designating an arbitrary position of the waveform data and a parameter setting address indicating a specific position are numerically displayed. The area R4 indicates the switch function of the function switch 25. The upper row shows the switch function when the shift switch 24 is not pressed, and the lower row shows the switch function when the shift switch 24 is pressed.

In the region R1, the mode of the current display screen is the quick setting mode, the displayed waveform data name is MyVocal, and the horizontal axis of R2 extends from the left end to the right end. Indicates that the display time width is 12.5 milliseconds. Also,
The letter S indicates that it is waveform data relating to a stereo signal, and ZRLL displayed on the right side thereof indicates other attribute information.

In the region R2, a part or all of the currently selected waveform data is graphically displayed with the horizontal axis as a time axis as described above, and the vertical lines a, A vertical line b indicating the position of c and the monitor address is displayed, and the symbol name of the line is displayed below each vertical line.

In a region R3, a waveform and a loop length are displayed as other parameters together with various parameter setting addresses and monitor addresses. In the example shown in the figure, WVS represents a waveform start address, WVE represents a waveform end address, SLS represents a sustain loop starter address, SLE represents a sustain loop end address, and Mn represents a monitor address. Also, W
VL represents a waveform length, and SLL represents a sustain loop length. Note that a rectangular area indicated by CS represents a cursor.
Is the cursor key 2 located at the lower right of the display 8
The user can move up and down or left and right by the operation 2. In the above display state, the parameter setting addresses such as WVS and WVE are stored in the registers assigned to the RAM 14, and the CPU 12 reads the data in the registers in the RAM 14 and the waveform data in the waveform RAM 4 at the same time. Then, the data is displayed on the display 8. Since these parameter setting addresses indicate the setting address of a specific position such as the start address and end address of the currently displayed waveform data, this register and means for designating the parameter setting address by its display are constituted. I do.
Further, the monitor address represented by Mn specifies an arbitrary position of the waveform data displayed in the area R2, and this monitor address is also allocated in the RAM 14 like the parameter setting address. It is stored in a predetermined register. Then, the CPU 12 controls the display position of the waveform data so that the position of the monitor address always appears within the display range of the region R2. Therefore, in any case, the position of the monitor address always exists within the display range of the region R2. In the example shown in the figure, the vertical line indicated by b is the position of the monitor address. Further, an arbitrary parameter setting address, monitor address, or length can be selected by the cursor CS. As described later, when the parameter setting address selected by the cursor CS is changed, the changed (newly selected) is automatically performed according to the mode or through a predetermined operation.
The parameter setting address is loaded into the monitor address, and the monitor address is controlled to be equal to the changed (newly selected) parameter setting address. As a result, the display area of the waveform data is automatically adjusted so that the position of the monitor address falls within the display screen of the region R2, and the display screen jumps to the changed (newly selected) parameter setting address. .

Next, the function of each switch in the region R4 will be described.

The Qui shown in the upper part of the region R4
“c”, “Proc”, “Loop”, and “Parm” indicate switches of a quick setting mode, a process setting mode, a loop setting mode, and a parameter setting mode, respectively. FIG.
Since the display is in the quick setting mode, “Quic” is highlighted. “Scrb” is a scrub playback switch. The scrub reproduction means a function of reproducing and generating waveform data corresponding to a monitor address that changes when the jog / shuttle dial 20 is rotated. When this switch is on, it keeps blinking, indicating that the scrub playback function is on. When the jog / shuttle dial 20 is operated at this time, the waveform data is reproduced in accordance with the change of the monitor address. The operation of the jog / shuttle dial 20 is as follows.
Since the monitor address is continuously changed, accordingly, the waveform data flows rightward or leftward so that the position of the monitor address is located on the display screen. The difference between the jog dial and the shuttle dial will be described later.

"Time" is a switch for extending or shortening the reproduction time. That is, a parameter input & expansion / contraction processing execution screen for expanding / contracting the reproduction time without changing the pitch of the tones to be generated is started. “Buff” opens a pop-up screen for performing an operation for storing or recalling the currently edited data in a temporary buffer for temporarily storing the data being edited. This temporary storage buffer is used, for example, when it is desired to return to the state in the middle of the editing performed so far.

Next, the switch when the shift switch 24 is pressed (the switch displayed in the lower part of the region R4) will be described.

"♪ Mon" is a switch for causing the waveform data to be reproduced at the normal speed from the position of the current monitor address.

As described above, "Job" opens a pop-up screen for editing the waveform data in the range specified by the region by an operation such as cut, copy, and paste.

"Jump" is a switch relating to the present invention.

The Jump function is divided into three modes in a parameter setting mode described later. Each mode is an auto mode, an action mode, and a manual mode.

When the auto mode is set, this "Jump" is highlighted, indicating that the switch itself does not function. When the cursor CS jumps to the position of another parameter setting address in the region R3 and the parameter setting address selected by the cursor CS is changed, the changed (newly selected) parameter setting address is used. Automatically loaded to monitor address. As a result, the display portion of the waveform data moves so that the waveform data loaded to the monitor address, that is, including the newly selected parameter setting address is displayed in the region R2. That is, the display range on the waveform data jumps to the position of the parameter setting address where the cursor CS has moved. In this case, even when the value of the parameter setting address selected by the cursor CS is changed by the numerical keys, the waveform data jumps to the changed parameter setting address.

In the action mode, there is no automatic jump when the cursor CS is moved to another parameter setting address as in the auto mode. However, when the "Jump" switch is pressed, a jump operation similar to that in the auto mode is executed for the parameter setting address at the cursor CS at that point.

In the manual mode, a pop-up screen for inputting a jump destination is opened when the "Jump" switch is operated regardless of the movement of the cursor CS as described above. FIG. 8 used in the following description of the operation.
Indicates a jump menu that is popped up at this time. In the jump menu, all other parameter setting addresses that cannot be displayed due to restrictions on the screen in the region R3 are also displayed at the same time. By selecting an arbitrary parameter setting address in this jump menu using the cursor (operating the "Go" switch),
It is possible to jump to the waveform data where the selected jump address is located. If the "Edit" switch is operated before the "Go" switch is operated, the jump is stopped and the screen returns to the screen before the pop-up of the jump menu. "M → A" and "A → M" 3 is a switch according to the invention.

"M → A" loads the monitor address to the parameter setting address currently selected by the cursor CS, and makes the selected parameter setting address equal to the monitor address at that time. Also,
“A → M” loads the parameter setting address selected by the cursor CS to the monitor address, and makes the monitor address equal to the parameter setting address selected at that time.

As described above, since the monitor address is always displayed in the area R2, when the "A → M" switch is operated, the position of the parameter setting address selected by the cursor CS is changed to the monitor address in the area R2. Will be displayed at the position.

The two switches arranged on the right side of “A → M” are switches for expanding and reducing the time width on the horizontal axis of the region R2.

In the above quick setting mode screen, only the waveform start, end address, and start and end addresses of the sustain loop can be selected as the parameter setting address, and the length and suspending of the waveform data can be selected as the length. Since only the length of the loop is possible, it is possible to edit only these. For example, change the waveform start address using the numerical keys (in this case, if the length is not locked, the length data is also automatically changed), change the value of the sustain loop start address, or Or change the length data. Further, by turning on the “Job” switch, various waveform editing operations can be performed on the area specified by the parameter setting address.

Next, the process setting mode will be described with reference to FIG.

As described above, in the process setting mode, an arbitrary region in the waveform data can be defined as a region region, and various editing operations can be performed on this region by a job. .

A characteristic feature of the screen shown in FIG. 5 in comparison with the screen shown in FIG. 4 is that the number of switches “♪ Rgn” and “R♯ ++” are increased in the switches shown in the region R4. .

The region is set by selecting one of the region numbers 1 to 3 with the "R $ ++" switch.
This can be performed by displaying the information in the region R3. By sequentially pressing this switch, the parameter setting address and the length of the region displayed in the region R3 are sequentially rotated and displayed from the region number 1. A region that cannot be set on the quick setting mode screen shown in FIG. 4 can be set on this process setting screen, and allows editing for that region. The vertical line d shown in the region R2 of the figure indicates the position of the start address of the region of the currently designated number, and the vertical line of e indicates the position of the end address of the region. Although the positions of some switches are different from those of the display screen shown in FIG. 4, switches having the same display name have the same function. The "♪ Rgn" switch newly displayed on this screen is a switch for starting the reproduction of the waveform data from the start address of the region specified on the display screen R3. The “Lock” switch is a selection switch for setting the length value selected by the cursor CS to a locked state or an unlocked state. As described in FIG. 4, if the length value is not in the locked state, when the start address is changed, the length value is automatically changed. if,
If this switch is set to the locked state,
Changing the start address automatically changes the end address so that the length is constant.

In the process setting mode shown in FIG. 5, compared to the quick setting mode in FIG. 4, a job for a region, that is, editing can be performed, so that more detailed editing can be performed. Note that some preset values can be given in advance as selectable regions. As the type of the preset, a length between addresses at a specific position such as a period from the beginning to the end of the waveform data, a period from the start to the end of the sustain loop, and the like can be considered. In this case, the preset value is given by a region number other than the already used “1” to “3”. When this preset value is used, when the parameter setting address corresponding to the preset value is changed, the address of the region is automatically maintained so as to match the change.

Next, the loop setting mode will be described with reference to FIG.

As described above, in the loop setting mode, a delicate editing of the sustain loop can be mainly performed. As characteristic switches shown in the region R4, an “X fd” switch, a “♪ Lp” switch,
This is a “Rel” switch.

The "X fd" switch activates a pop-up screen for inputting parameters for cross-fading from the loop end to the loop start in the range to be looped. The “Rel” switch sets whether the area of the waveform data to be displayed is in the range of the release loop or the range of the sustain loop. This switch is a toggle switch, "Rel" and "Su"
s "are displayed in order.

Further, “LpTum” displayed in the area R3
The "e" switch determines the degree of loop tune for finely adjusting the pitch of the loop portion, and the value can be determined by a numerical key.

In this loop setting mode, "Jo
Various edits can be made using the "b" switch. Other switches have the same functions as the switches already described.

Next, the parameter setting mode will be described with reference to FIG.
This will be described with reference to FIG.

In this mode, parameters different from those shown in region R3 of the display screen in each of the modes shown in FIGS. 4 to 6 are set. As a parameter, a configuration such as a sampling frequency (Freq) can be set as one of other parameters in addition to a parameter such as a sampling frequency (Freq). As the configuration, "Scale" indicating the display unit of the horizontal axis in the display screen region R2, the number of clocks per bar "B"
"PM" and the number of beats per bar "TPM"
Adrs "," ScrbDev "and" ScrbSp "
d ”.

"JmpAdrs" determines the mode of the "Jump" switch available in FIGS. The modes that can be selected here include the auto mode “a” as described above.
uto ", an action mode" act ", and a manual mode" man ". This mode is switched and displayed by predetermined switches "+" and "-" included in the numerical value input switch group 21. In the example shown in the figure, the action mode “act” is set as the jump mode.

"ScrbDev" designates which of the jog dial and the shuttle dial is valid at the time of the above-described scrub reproduction. As shown in the drawing, when both is selected, scrub playback is performed using either dial. When one of the dials is designated, scrub playback is performed when the designated dial is operated, but scrub playback is not performed when the other dial is operated. That is, in that case, the monitor address changes and the display waveform data simply moves to the right or left.

"ScrbSpd" designates whether the maximum speed at the time of scrub reproduction is set to the standard speed or triple the standard speed. When the normal shown in the figure is designated, a standard speed (writing speed at the time of recording) is designated. When 3 times is specified, the playback speed is about 3 times faster at the same dial rotation speed than normal, but the moving speed of the display waveform is also faster, so that the target position is quickly reached and scrub playback is performed. Sometimes the playback pitch is high.

"Scale" sets the time direction unit of the waveform display screen. The unit includes a memory address (address), a time (time) and a beat (b).
eat). “BPM” and “TPM” are “Sca
"le" is a parameter used when a beat is selected as a time unit, and specifies the number of tempo clocks for one bar and the number of beats for one bar, respectively.

FIG. 8 shows the above-mentioned jump menu. As shown in the figure, the menu screen shows all parameter setting addresses for the currently selected and displayed waveform data. Therefore, by moving the cursor to an arbitrary position of the parameter setting address and operating the "Go" switch, it is possible to jump to the address selected by the cursor.

FIGS. 9 and 10 show examples of display waveforms in the region R2 of the display screen. In FIG. 9, in the parameter setting mode, “Scal
Since “e” is set to time, a unit of time msec is displayed as a time axis scale on the display screen. In FIG. 10, since a beat is selected as “Scale”, “time” is displayed as a unit of the beat on the display screen.

FIG. 10 shows the waveform data reduced in the time axis direction as compared with FIG. Here, “S>” and “<S” in FIGS. 9 and 10 are sustain loops, “R>” and “<R” are release loops, and “1”.
> ”And“ <1 ”are the region number 1 and“ W
">" And "<W" are marks indicating the start address and end address of the waveform. “M” is a mark indicating the position of the monitor address.

Next, the operation of the electronic musical instrument in the waveform edit mode will be described with reference to the flowcharts shown in FIG.

FIG. 11 shows the main operation of the electronic musical instrument.

When the system is reset by turning on a power switch or the like, various initial settings are performed in n1, and MIDI data reception processing is performed in n2. At this time, if the received MIDI data has a note-on,
The note-on reception event routine shown in FIG. 12 runs.
After the completion of the MIDI reception process, the control waits for the L mode designation at n3, that is, the designation of any one of a recording process mode, a waveform edit mode, a waveform allocation mode, and other modes. In the case of the recording processing mode, the process proceeds to n5, in which a signal of a sound of a piano or the like input from the microphone 1 is sampled and stored in the waveform RAM 4 as waveform data. When the waveform assignment mode is designated, n7
, The whole pitch is divided into several ranges, and a waveform is assigned to specify one waveform for each range.

Hereinafter, the note-on reception event routine and the operation in the waveform edit mode of n6 will be described.

In the note-on reception event routine, the received MIDI channel number is loaded into the register m, and the note number is loaded into the register NN.
Next, processing for assigning a sound channel for new sound generation is performed. Subsequently, the tone color data corresponding to the MIDI channel number set in the register m is stored in the register TCm.
(Tone data is preset in this register), and the sound is prepared by setting the assigned channel together with the pitch MN. That is, since the timbre and the pitch are determined, the waveform in the timbre and the tone range determined by the waveform assignment processing of n7 is determined, and therefore, each parameter setting address (WVS, WV) of this waveform data
E, SLS, SLE, RLS, and RLE) are set as the assigned channels of the reading unit 5 (n12).
Further, a note-on is transmitted to the assigned channel, and the process ends (n13).

By the above processing, the sound generation start is instructed to the assigned channel, and the reading unit 5 starts reading the waveform data and outputs the read waveform data to the sound system 6. Is played as is.

FIG. 13 shows an S mode setting routine in the waveform edit mode at n6 in FIG.
That is, in the S mode, as shown in FIG. 3, a quick setting mode, a process setting mode, a loop setting mode,
When there is a parameter setting mode and a switch (function switch 25) corresponding to each S mode is pressed, a corresponding screen is displayed in any of n22 to n25.

FIG. 14 shows the S set as described above.

At n30, a tone generation channel assignment process is performed, and the parameter setting address of the displayed waveform corresponding to the pressed switch is loaded to the monitor address MA.

When the pressed switch is "♪ Mon", this processing is skipped. After n31,
The start address position of the switch pressed on the monitor address position on the display screen overlaps. Next, the reproduction preparation of the waveform from the monitor address MA is instructed to the assigned channel, and a note-on is sent to the channel. Note that note-on is transmitted at n13 in FIG. 12, and note-on is also transmitted at n33. This is because it is necessary to generate note-on as an instruction to start sound generation to the reading unit 5 when the note-on is not received by the MIDI reception processing and the waveform data displayed manually is selected. . At n34, the read address of the waveform data of the read section 5 advances, and as the waveform data is reproduced, the monitor address is updated on the display screen, the vertical line b is moved, and the monitor address is displayed. Perform display control to scroll so as not to deviate from the range. Here, the display scrolling method is shown in FIG.
This will be described with reference to FIG.

The display scroll has three modes as shown in FIG. The first mode is a mode in which the position of the vertical line b of the monitor address MA is fixed and the waveform is moved rightward or leftward as shown in FIG. The second mode is a mode in which the vertical line b of the monitor address MA is moved to the left or right while the position of the waveform is fixed, as shown in (2). In this case, when the line b comes to the left end or the right end, the line b is fixed there and the waveform is moved in the opposite direction. Still another mode is to move the vertical line b while fixing the position of the waveform as shown in FIG. 3 (3), and when it comes to the end, hold the line b at the opposite end. In this mode, the same line b is moved in the same direction again.

The display scroll includes the above (1) to (3)
Any of the display modes can be selected, and that mode can be selected by another mode specification routine of n8 specifying the L mode.

Next, a routine when the jog or shuttle dial is operated will be described with reference to FIG.

When a jog or shuttle dial operation event occurs, it is determined whether a waveform is currently displayed. If it is not a waveform display, other processing is performed (n41) and the processing ends. After confirming the waveform display state, the monitor MA is moved according to the operation amount detected by the dial. Here, in the case of a jog dial, the moving amount of the monitor address MA is determined according to the detected dial rotation speed, and in the case of the shuttle dial, the monitor address MA is monitored according to the detected dial rotation angle (displacement from the reference angle). The moving amount of the address MA is determined. At this time, the maximum speed at the time of moving the monitor address is changed depending on whether the maximum speed of the scrub reproduction of "ScrbSpd" in FIG. 7 is set to the standard speed or to three times the standard speed.

The moving speed of the monitor address until the maximum speed is reached also changes depending on whether the mode is × 1 or × 3. In this case, if the operation speed of the jog or shuttle is slow, the MA moves. The operability is improved by lowering the speed and increasing the moving speed of the MA rapidly when the operating speed is increased. When the monitor address MA is moved, the display position of the waveform is updated according to the value of MA (n43). Then, if the scrub playback mode is set for the jog or shuttle dial at that time, the process proceeds to n45, where the waveform reading unit 5 reads and plays back the waveform corresponding to the movement of the monitor address MA for the channel being scrubbed. Instruct.

FIG. 17 shows the "M → A" switch-on event routine, and FIG. 18 shows the "A → M" switch-on event routine.

In FIG. 17, when the "M → A" switch-on event occurs, the monitor address at this time is loaded to the parameter setting address selected by the cursor. First, at n50, the monitor address is selected by the cursor CS. It is determined whether or not the current parameter is an address parameter (parameter setting address). If not, the process ends. If the parameter setting address has been selected, at n51, the monitor address MA is loaded to the parameter setting address specified by the cursor CS. Then, the display state is updated to the display state according to the value. In this case, the updated display content is the update of the address value in the area R3, and the waveform display in the area R2 does not change.

On the other hand, in FIG. 8, when the "A → M" switch-on event occurs, the same check as in n50 is performed in n53, and when it is confirmed that the parameter setting address is selected by the cursor, the cursor is checked. The selected parameter setting address is loaded to the monitor address (n54). Then, the display range of the waveform is updated so that the position corresponding to the value of the monitor address MA is displayed in the region R2, and the display value of “Mn” in the region R3 is updated (n55).

Therefore, in FIG. 17, the waveform display range is unchanged, but in FIG. 18, the waveform display range is updated.

As described above, the "M → A" switch and the "A →
By using the "M" switch, it is possible to immediately change the waveform display to a desired state, and there is an advantage that operability when starting a job is greatly improved.

Next, the cursor switch event routine will be described with reference to FIG.

When the cursor key 22 arranged at the lower right of the display 8 is operated, this routine is entered. First, when each of the cursor switches (any of the four cursor switches) is operated, the cursor CS is set and moved in the moving direction of the operated cursor. (N60). Then, the parameter number corresponding to the new cursor position is set in the register PN (n61). Therefore, the register PN indicates the number of the parameter at the cursor position, and this value is used in FIGS. Next, it is determined whether the jump mode is the auto mode and whether the parameter number designated by PN is one of the parameter setting addresses. If the cursor has selected the parameter setting address and the jump mode is the auto mode, the process proceeds to n63, and the parameter setting address selected at that time is loaded to the monitor address (n63). Then, the display range of the waveform is updated according to the value of the monitor address MA (n64). If the jump mode is not the auto mode, or if the parameter setting address has not been selected, the processing of n63 and below is skipped.

By the above operation, for example, the cursor CS is moved to WV on the quick setting mode display screen of FIG.
From E to WVS, when WVS is selected, when the jump mode is the auto mode, the value of the monitor address becomes equal to the value of WVS, and the monitor address newly loaded in the region R2 accordingly. The display of the waveform data is updated so that the position is displayed.

FIG. 20 shows the "Jump" switch-on event routine.

When the jump mode is the auto mode, this switch is invalid because it is highlighted. When the switch is not pressed, n71 or n73 is effective.
The following is performed: If the jump mode is the action mode, the process proceeds to n71, where n6 in FIG.
3, n64. In the case of the manual mode, a jump menu shown in FIG. 8 is displayed in a pop-up at n73 and below, and the parameter setting address of the display position number j selected by the cursor is loaded to the monitor address MA (n75). The display range of the waveform is updated according to the value of the address MA (n76).

As described above, in the operation shown in FIGS. 19 and 20, in the auto mode or the action mode, the desired position (cursor CS
Jump to a certain parameter setting address), and when setting to the manual mode, jump to an arbitrary parameter setting address. As a result, there is an advantage that the operability from changing various parameter setting addresses or starting a job to performing an editing operation is significantly improved.

In the embodiment described above, except for the characteristic part according to the present invention, other characteristic parts for improving operability are as follows.

First, when the scrub playback mode is set and the jog / shuttle dial is operated, the display is scrolled in accordance with the playback of the waveform. As shown in FIG. Either a method of running the display of the monitor address or a method of running the waveform with the display of the monitor address fixed can be selected.

By selecting the scrolling method of the waveform display, a display mode preferred by the operator can be obtained, which leads to an improvement in operability. Note that the scrolling method specifically includes the methods shown in (1) to (3) of FIG.

Further, it is possible to select whether the maximum speed at the time of the scrub reproduction is set to the standard speed or n times (for example, 3 times) the standard speed. In this way, for example, when the waveform data is short, the standard speed is set, and when the waveform data is long, the standard speed is set to three times, so that the target position can be reached quickly. When set, when the monitor address is moved at the maximum speed (during scrub playback), the sound of the pitch at the time of recording is played, and the operability is improved, such as making it easier to find the target position. .

Also, "♪ Mon", "♪ Rgn", "♪
As indicated by the “Lp” switch, the start address at the time of reproduction can be set to any of the monitor address, the start address of the region or the root. Since the start of the reproduction is only required to perform one-touch operation of the corresponding switch, it is possible to easily confirm each parameter setting address and the like, which also leads to improvement of operability.

Further, in the parameter setting mode screen of FIG. 7, the time direction unit of the display screen can be set to any one of a memory address, a time, and a beat as a configuration of “Scale”. Can be selected as appropriate. Therefore, this also improves operability.

An address which seems to be an appropriate position can be set as it is as an end address of the loop or the like, and there is an advantage that operability at the time of waveform editing becomes very good.

On the contrary, the parameter setting address can be made equal to the monitor address. In this case, when the selected parameter setting address is changed, the monitor address is made equal to the changed parameter setting address immediately.
