A return switch RWD, a record switch REC for starting recording, and the like are included. When the edit window selection switch ES is selected by operating the mouse on the screen of FIG. 3, the screen of FIG. 3 is switched to the screen of FIG. Also, when the song window selection switch SS in the control bar CB is selected by a mouse operation on the screen of FIG. 4, the screen of FIG. 4 is switched to the screen of FIG.

Here, the pattern sequence setting operation on the screen of FIG. 3 will be described. First, the arrow pointer AR
Select Then, the pointer AR is set to a desired tag T
A desired genre is selected by clicking on G and clicking with the mouse 18. As a result, for example, “Rock1”
Is displayed as shown in the figure.

Next, a desired accompaniment pattern is selected. When selecting an accompaniment pattern of the first section the main M ₁ is dragged with the mouse 18 by applying to the arrow pointer AR to the icon corresponding to the desired accompaniment pattern. If you want to select an accompaniment pattern of the first main M ₁ other than the section, "Intro" to the arrow pointer AR,
A desired section is selected by clicking on either “Main2” or “Ending” with the mouse 18. A black circle is displayed for the selected section. In such a state, the arrow pointer AR is put on the icon corresponding to the desired accompaniment pattern and dragged with the mouse 18.

In any case, the dragged icon can be mounted on the sequence display PSD. The icon that has been dragged first may be mounted in the position locator PL next to the start mark SM. At the start of dragging, the dragged icon is displayed with its yin and yang inverted, and when the crucifixion ends (switch off the mouse 18), the icon returns to the non-inverted display at that position.

Before selecting a desired icon by dragging, it is convenient to be able to preview the performance based on the accompaniment pattern corresponding to the icon. In this embodiment, it is possible to shift to the trial listening mode by placing an arbitrary pointer such as an arrow pointer AR at the center of a desired icon.

For example, when the arrow pointer AR is pointed at the center of a desired icon, the arrow pointer AR changes to a speaker pointer SP. Then, when the mouse 18 is clicked, the performance starts. The performance at this time corresponds to the accompaniment pattern data of the section selected on the display section SC of the accompaniment pattern data corresponding to the icon selected by the speaker pointer SP, and the icon selected by the speaker pointer SP. This is automatically performed based on the code sequence data of the section selected by the display unit SC among the code sequence data. As an example, the section of the intro Int is selected with an icon corresponding to S ₁ with respect to the accompaniment style data genre of FIG 2 is selected,
Automatic performance is performed based on the accompaniment pattern data of the intro Int in the accompaniment pattern data APD and the chord sequence data of the intro Int in the chord sequence data CSQ.

When the user clicks in the state of the speaker pointer SP, the selected icon is displayed with its inversion reversed, and the speaker pointer SP is displayed in step 8 in FIG.
At 4, the speaker shape changes from a simple speaker shape to a speaker shape in a sound emitting state (hereinafter, referred to as a playback pointer) as shown in parentheses. Then, in the state of the playback pointer, the automatic performance is repeated until a stop command is given.

The stop command can be given by clicking with the mouse 18. The automatic performance stops in response to the stop command, and the playback pointer returns to the original pointer shape (when the pointer shape changes to a speaker, the previous pointer shape [for example, an arrow pointer]).

[0037] without clicking with the mouse 18 in the state that has changed from Aropointa AR to the speaker pointer SP, and drag, play is not performed, the pointer shape spin
Back from over mosquitoes to Arrow. Then, the icon moves according to the drag operation of the mouse 18.

By repeating the drag operation while performing the audition as described above as necessary, a plurality of desired icons can be arranged and attached on the sequence display PSD. Thereafter, the icons can be rearranged by selecting and moving one or more desired icons on the sequence display PSD. Also in this case, the accompaniment pattern can be previewed as needed.

There are three icon selection methods: single selection, intermittent multiple selection, and multiple selection of range designation. In any of these methods, the selected icon is displayed with its inversion reversed. .

The single selection is performed by pointing the arrow pointer AR to a desired icon and clicking with the mouse 18. The intermittent multiple selection is performed by successively selecting a plurality of desired icons by a mouse operation in the same manner as in the case of single selection while holding down the shift key on the keyboard of the personal computer. The multiple selection of range specification is a selection method of specifying a desired range and collectively selecting a plurality of icons in the desired range. In this case, assuming the selection range, the arrow pointer AR is applied to one corner of the arrow and dragged with the mouse 18, and a rectangular frame of dot display showing a change in the selection range as the pointer AR moves appears on the screen. When the mouse 18 is turned off while the icons are surrounded by a rectangular frame, a plurality of icons within the rectangular frame are selected at once.

One or more icons selected by any of the selection methods can be freely moved on the sequence display PSD by dragging with the mouse 18. When a plurality of icons are selected, all the icons related to the selection can be dragged by dragging any one icon related to the selection.

When a trial listening is desired on the sequence display PSD, the speaker pointer SP is selected.
Then, when the speaker pointer SP is placed on a desired icon and clicked with the mouse 18, an automatic performance is started based on the accompaniment pattern data and the code sequence data corresponding to the clicked icon. In this case, the accompaniment pattern data and the chord sequence data correspond to the selected section. The automatic performance is performed only once, and is not repeated. Therefore, when the user wishes to listen to the music a plurality of times, he or she may perform the click operation each time the performance is completed.

After arranging a plurality of desired icons on the sequence display PSD in a desired arrangement and attaching them,
Perform the connection operation. That is, after selecting the pencil pointer PN and dragging the pointer PN to one of the icons to be connected with the mouse 18, the connection line L appears as the pointer PN moves. Then, when the connection line L reaches the other icon to be connected, the mouse 1
When the switch 8 is turned off, both icons are connected by a connection line L. Such a connection operation is performed on a plurality of desired icons in the order of performance. As a result, the connection state is displayed on the sequence display PSD as shown in the figure, and the pattern sequence storage unit PSM of the memory 16 indicates the playing order of the accompaniment pattern data corresponding to the displayed connection state. Pattern sequence data is stored.

On the sequence display PSD, even after connecting the icons, the above-mentioned trial listening can be performed for each icon. To listen to the performance from the beginning to the end of the connected icon in accordance with the pattern sequence data, the performance can be started by placing the arrow pointer AR on the play switch PLY and clicking with the mouse 18.

FIG. 4 shows an edit window 20B as another screen of the display device 20, and this window 20B is used for correcting or creating code sequence data. Edit window 20B
Includes three display units: a chord palette CP, a part tone color display unit PV, and a chord sequence display CSD.

The code pallet CP has the same 1 as in FIG.
Zero tags TG are displayed, and a block area BA related to the selected tag is displayed. In the block area BA, a preset key (for example, “C”) and a preset tonality (measure “Maj” or minor “mi”) for a style (for example, “rock and roll”) related to the selection are provided.
n ") is displayed. These keys and tonality can be changed, but the description of the changing means is omitted.

In the block area BA, 15 code beat blocks CB ₁ , CB ₂ ... CB ₅ ... CB ₁₅ representing chords suitable for the style, key and tonality of the selection.
Is displayed. These beat blocks include CB ₁ ,
Two beats such as CB ₂ and four beats (one bar) such as CB ₅ and CB ₁₅ are included.
Bar). Depending on the genre, a beat block representing a chord including tension may be displayed. The color of the beat block is determined for each chord type.

On the part tone color display section PV, tone colors of four parts, drum, bass, chord 1 and chord 2 are displayed. In addition, generation or non-generation of a performance sound can be selected for each part. For a part that generates a performance sound, an X mark is displayed in a square in front of the part name.

In the code sequence display CSD, a tool box TB and a control bar CB are displayed in the same manner as in FIG. 3, and an edit code sequence CSE corresponding to the style relating to the selection is displayed. The accompaniment pattern combined with the chord sequence CSE is displayed by the icon SI and the section mark S. In the example of FIG. 4, the accompaniment pattern is
The icon SI ₂ is accompaniment pattern corresponding Intro.

Here, the code sequence setting operation on the screen of FIG. 4 will be described. First, the arrow pointer AR is selected. Then, the pointer AR is assigned to a desired beat block on the code palette CP and dragged with the mouse 18 to attach the beat block to a desired position of the code sequence CSE on the sequence display CSD. In this case, gluing can be performed in units of one beat, and when a beat block already exists at a desired position, overwriting is performed in units of one beat. At the start of dragging, the dragged beat block is displayed with the yin and yang inverted, and after the crucifixion is completed, the beat block returns to the non-inverted display.

Before a desired beat block is selected by dragging, a performance based on the chord indicated by the beat block can be previewed. That is, it is possible to shift to the trial listening mode by placing an arbitrary pointer such as the arrow pointer AR at the center of the desired beat block.

For example, when the arrow pointer AR is placed at the center of a desired beat block, the arrow pointer AR becomes
It changes to the speaker pointer SP. And mouse 18
Click on to start playing. The performance at this time is automatically performed based on the accompaniment pattern data corresponding to the display of the icon SI and the section mark S, and the chord data or chord sequence data corresponding to the beat block selected by the speaker pointer SP. You.

When the user clicks in the state of the speaker pointer SP, the selected beat block is displayed with its inversion inverted, and the speaker pointer SP changes to a playback pointer. Then, in the state of the playback pointer, the automatic performance is repeated until a stop command is given.

The stop command can be given by clicking with the mouse 18. The automatic performance stops in response to the stop command, and the playback pointer returns to the original pointer shape (when the pointer shape changes to a speaker, the previous pointer shape [for example, an arrow pointer]).

[0055] without clicking with the mouse 18 in the state that has changed from Aropointa AR to the speaker pointer SP, and drag, play is not performed, the pointer shape spin
Back from over mosquitoes to Arrow. Then, the beat block moves according to the drag operation of the mouse 18.

By repeating the drag operation while performing the audition as described above as necessary, a desired plurality of beat blocks can be glued or overwritten on the sequence display CSD. Thereafter, a desired code sequence can be set by selecting a portion requiring correction on the sequence display CSD in units of one beat and moving it in the horizontal direction, or changing the code content. Also in this case, a trial listening can be performed if necessary.

As the beat block selection method, there are four methods of single selection, one bar selection, continuous selection, and multiple selection of range specification.

The single selection is performed by placing the arrow pointer AR on a desired beat and clicking with the mouse 18. Selection of one measure is performed by placing the arrow pointer AR on an arbitrary beat belonging to a desired measure and double-clicking with the mouse 18. The continuous selection is performed by placing an arrow pointer on the first beat of a desired section and dragging it with the mouse 18 to the end of the section, and a plurality of beats belonging to the dragged section are collectively selected. The multiple selection of the range specification is a method of specifying a desired range and collectively selecting a plurality of beats in the range. The specific operation is the same as that described above regarding the icon selection.

To cancel the selection, the mouse 18 is clicked on a portion other than the beat block. At this time, the reverse display returns to the non-reverse display. Also, when the pointer is changed in the tool box TB, the selection is released and the reverse display is returned to the original state.

One or a plurality of beat blocks selected by any of the selection methods can be freely moved right or left on the chord sequence CSE by dragging with the mouse 18, and can be attached in units of one beat. When a plurality of beat blocks are selected, all of the selected beat blocks can be dragged by dragging any one of the selected beat blocks.
At the start of dragging, the dragged beat block is displayed with the yin and yang inverted, and after the crucifixion is completed, the beat block returns to the non-inverted display. When dragging to a place where a beat block already exists, it is overwritten. The beat block of the movement source is a blank beat block.

To change the code content of one beat in the code sequence CSE, select the pencil pointer PN. Then, a pencil pointer PN is set to a desired beat Bx.
And clicking with the mouse 18, a two-level input pop-up menu of root and code type appears on the screen. Therefore, a desired route and a chord type are selected from the pop-up menu, and dragged to a position of one beat Bx and attached.

When the beat block is moved or the code content is changed as described above, the display content of the code sequence CSE is changed each time, and the code in the memory 16 is changed in accordance with the new display content. The code sequence data in the sequence storage unit CSM is rewritten.

When a trial listening is desired on the sequence display CSD, the speaker pointer SP is selected, the speaker pointer SP is applied to a desired bar on the code sequence CSE, and the mouse pointer 18 is clicked. Then, the performance starts from the clicked bar, and the performance is stopped at the end of the chord sequence CSE and is not repeated. When a click is made in a portion other than the beat block, the performance is performed from the beginning to the end of the chord sequence CSE. This performance is not repeated. If you want to re-listen in any case, just click again.

FIG. 5 shows the flow of the processing of the main routine. This routine is started when the power is turned on or the like.

First, at step 30, an initialization process is executed, and various registers in the memory 16 are initialized. Then, the process proceeds to a step 32, wherein a mouse processing subroutine is executed as described later with reference to FIG.

Next, at step 34, other processing is executed. The processing in this case is as follows: (a) In the floppy disk set in the FDD 22, the Fa in FIG.
(b) a process of registering an accompaniment pattern code sequence or the like corresponding to a favorite icon in a recording area corresponding to “volite”.
There is a process of registering a desired accompaniment pattern, a code sequence, and the like from a predetermined format floppy disk in a recording area corresponding to “Disk” in FIG.

FIG. 6 shows a mouse processing subroutine. In step 40, it is determined whether or not the mouse 18 has been clicked. If the determination result is affirmative (Y), the process proceeds to step 42, and a subroutine of a click process is executed as described later with reference to FIG.

When the result of the determination at step 40 is negative (N) or when the process at step 42 has been completed, the routine proceeds to step 44, where it is determined whether or not the mouse 18 has been dragged. If the result of this determination is affirmative (Y), the routine proceeds to step 46, where a subroutine of a drag process is executed as described later with reference to FIG.

When the result of the determination at the step 44 is negative (N) or when the processing at the step 46 has been completed, the routine proceeds to a step 48, where it is determined whether or not the mouse 18 has been moved. If this determination is positive (Y), step 5
Then, the subroutine of the movement process is executed as described later with reference to FIG.

When the result of the determination at step 48 is negative (N) or when the processing at step 50 is completed, the routine returns to the routine of FIG.

FIG. 7 shows a subroutine of the click process. In step 60, the position where the click operation is performed is determined to be one of an icon, a beat block, a control bar, and others.

When the click operation position is an icon, the process proceeds to step 62, and a subroutine of an icon click process is executed as described later with reference to FIG. Thereafter, the process returns to the routine of FIG.

When the click operation position is a beat block, the process proceeds to step 64, and a block click process is executed as described later with reference to FIG. After this, FIG.
Return to the routine.

If the click operation position is on the control bar, the process shifts to step 66 to determine whether the click operation position is the window selection switch (SS or ES in FIG. 3). If this determination is positive (Y), step 6
Then, the process proceeds to step 8 to perform a window switching process. That is, when the window selection switch is the edit window selection switch ES, the screen of FIG. 3 is switched to the screen of FIG. 4, and when the window selection switch is the song window selection switch SS, the screen of FIG. 4 is switched to the screen of FIG. . Thereafter, the process returns to the routine of FIG.

If the result of the determination in step 66 is negative (N), other processing (for example, performance start processing in accordance with the selection of the switch PLY) is performed in step 70, and then the routine shown in FIG. Return to

When the click operation position is not any of the icon, the beat block and the control bar, other processing is performed in step 72. The process here includes a process of loading accompaniment style data (FIG. 2) for one genre into the memory 16 from the floppy disk of the FDD 22 by selecting a tag.

Of the data loaded into the memory 16,
The code sequence data CSQ corresponding to the style related to the selection is stored in the code sequence storage unit CSM. Then, the data in the storage unit CSM is displayed as the editing code sequence CSE when the screen is shifted to the screen of FIG. After step 72, the process returns to the routine of FIG.

FIG. 8 shows a subroutine of the icon click process. In step 88, it is determined whether the pointer shape is an arrow, a speaker, or any other.

If the pointer has an arrow shape, the flow advances to step 82 to perform icon selection processing. The single icon selection process described above is performed in step 82. Thereafter, the process returns to the routine of FIG.

When the pointer is a speaker,
In step 84, the pointer shape is changed to playback as shown in parentheses. Then, in a step 86, it is determined whether or not the instruction by the speaker pointer is an icon on the icon palette IP. If the result of this determination is affirmative (Y), the routine proceeds to step 88, where a performance based on the accompaniment pattern and the code sequence data corresponding to the designated icon is started. This performance can be repeated.

Next, in step 90, it is determined whether or not the mouse 18 has been clicked. This judgment result is negative (N)
If so, the process returns to step 88, and the performance is continued until the mouse 18 is clicked. When the determination result of step 90 becomes affirmative (Y) in response to the click with the mouse 18, the process proceeds to step 92, where the performance is stopped and the pointer shape is returned to the original shape. Thereafter, the process returns to the routine of FIG.

If the decision result in the step 86 is negative (N), it means that it is an icon on the sequence display PSD, and the process proceeds to a step 94. In step 94, the performance based on the accompaniment pattern and the code sequence data corresponding to the icon designated by the speaker pointer is started. When the timing of the last bar of the first performance is reached, the process proceeds to step 92, where the performance is stopped and the pointer shape is restored in the same manner as described above. As a result, the performance is performed only once.

If the pointer shape is neither an arrow nor a speaker, other processing is performed in step 96. The processing here includes the above-described processing of deleting an icon using the eraser pointer. Thereafter, the process returns to the routine of FIG.

In the performance processing of step 88 or 94, the bass, chord 1 and chord 2 other than the drum part
The tone pitch indicated by the accompaniment pattern is modified as appropriate according to the chord indicated by the chord sequence data. Key event data representing the pitch based on such pitch correction processing is supplied to the tone generator of the electronic musical instrument 26 via the MIDI interface 24, so that the bass, chord 1 and chord 2 are automatically played. For the drum part, automatic rhythm performance is performed by supplying key event data indicating the percussion instrument name indicated by the accompaniment pattern of the drum part to the rhythm sound source section in the tone generator of the electronic musical instrument 26 via the MIDI interface 24. Done.

FIG. 9 shows a subroutine of the block click process. In step 100, it is determined whether the pointer shape is an arrow, a speaker, or any other.

If the pointer has an arrow shape, the flow advances to step 102 to perform beat block selection processing. The above-described processing for single selection of a beat block is performed in step 102. Thereafter, the process returns to the routine of FIG.

When the pointer shape is a speaker,
In step 104, the pointer shape is set to playback as in step 84 described above. And step 1
At 06, it is determined whether or not the instruction by the speaker pointer is a beat block on the code palette CP. If the result of this determination is affirmative (Y), the routine proceeds to step 108, where a performance based on the sequence data corresponding to the designated code block and the selected accompaniment pattern is started.
This performance can be repeated.

Next, in step 110, it is determined whether the mouse 18 has been clicked. If the result of this determination is negative (N), the process returns to step 108 and the performance is continued until the mouse 18 is clicked. If the result of the determination at step 110 becomes affirmative (Y) in response to the clicking of the mouse 18, the process proceeds to step 112, where the performance is stopped and the pointer shape is restored. Thereafter, the process returns to the routine of FIG.

The result of determination at step 106 is negative (N).
If so, it means that it is a beat block on the sequence display CSD, and the routine goes to step 114. In step 114, the performance based on the sequence data corresponding to the measure indicated by the speaker pointer and the selected accompaniment pattern is started. When the timing of the last bar of the first performance ends, step 1
In step 12, the performance is stopped and the pointer shape is restored in the same manner as described above. As a result, the performance is performed only once from the designated bar to the end.

If the pointer shape is neither an arrow nor a speaker, other processing is performed in step 116. The processing here includes the processing of deleting a beat block using the eraser pointer described above.
Thereafter, the process returns to the routine of FIG.

In the performance processing of steps 108 and 114, the drum, bass, chord 1 and chord 2 parts are automatically performed in the same manner as described above with reference to steps 88 and 94. Note that when a part other than the beat block is clicked on the sequence display CSD, an automatic performance is performed from the beginning to the end of the chord sequence CSE.
Step 72 is performed.

FIG. 10 shows a subroutine of the drag process. In step 120, it is determined whether the pointer shape is an arrow, a speaker, or any other.

If the pointer has an arrow shape, the process proceeds to step 122, where it is determined whether the starting point is an icon or a beat block. If this determination result is affirmative (Y), the process proceeds to step 124. If the starting point is an icon, the icon is moved and attached to the sequence display PSD. The movement of the icons is performed by either the icon palette IP or the sequence display PSD. When the start point is a beat block, the beat block is moved and attached to the sequence display CSD.
The movement of the beat block is performed using either the code palette CP or the sequence display CSD.

Next, at step 126, only when the beat block is attached, the code sequence storage unit CSM of the memory 16 is matched with the displayed code sequence.
Rewrite the code sequence data of And FIG.
Return to the routine.

If the determination result of step 122 is negative (N)
If so, the process moves to step 128 and other processes are performed. Examples of the processing here include the above-described multiple selection processing for range specification and continuous selection processing. After this,
It returns to the routine of FIG.

When the pointer shape is a pencil,
In Step 130, it is determined whether the dragging is between the icons on the sequence display PSD. If the determination result is affirmative (Y), the process proceeds to step 132, where the connection line L is connected from the start point to the end point. Then, the process proceeds to step 134.

In step 134, the pattern sequence data is written into the pattern sequence storage unit PSM of the memory 16 or the pattern sequence data in the storage unit PSM is rewritten according to the connection state of the displayed icon. Thereafter, the process returns to the routine of FIG.

If the result of the determination in step 130 is negative (N)
, The process returns to the routine of FIG. Also, when the pointer shape is neither the arrow nor the pencil, the process returns to the routine of FIG.

FIG. 11 shows a subroutine of the movement process. In step 140, the pointer is moved.

Next, in step 142, it is determined whether the pointer has entered the center of the icon or beat block. The size of the center of the icon or beat block is
It is predetermined in consideration of the size of the pointer. If the determination result of step 142 is affirmative (Y), the process proceeds to step 144.

In step 144, the pointer shape is changed to a speaker. As a result, a sound generation instruction can be made by clicking the mouse 18. Thereafter, the process returns to the routine of FIG.

The determination result of step 142 is negative (N)
If so, the process moves to step 146 to determine whether the pointer has deviated from the center of the icon or beat block. If the result of this determination is positive (Y), step 1
The process proceeds to step 48, where the pointer shape is restored.

The determination result of step 146 is negative (N)
Or when the processing of step 148 is completed, the routine returns to the routine of FIG.
