[0002]

2. Description of the Related Art Generally, in an automatic performance apparatus, an arbitrary position in performance data can be designated, and a designated index is called a "marker". By using such markers, for example, as shown in Japanese Patent Application Laid-Open No. 7-64547, a repeat function is provided in which two markers are set and a portion between them is played repeatedly. Such a repeat function is often used when performing repetitive practice in a performance lesson.

[0003] In general, when practicing a certain music, the music can be more easily acquired by dividing the music into short sections and repeatedly performing the music. The practice of this repetition is as follows. Practice only the first measure. Practice only the second measure. Practice through bars 1 and 2 Practice only the 3rd measure. Practice only in measure 4. Practice through measures 3 and 4. It is common practice to practice in units of powers of measure 2, such as practicing through measures 1 to 4. It is also often practiced to practice sequentially from the beginning of the song in units of two measures. further,
If it is difficult to practice even one bar, you may practice again in half or beat units.

When such a practice method is employed by an automatic performance device, the repeat section is moved in units of one measure or two measures, or the repeat section is doubled or reduced in half forward or backward. Operation is required.

However, according to the conventional marker setting method, when the repeat section is changed forward or backward in double or half units, the marker to be moved is temporarily erased and moved to a new position. A complicated operation of resetting the marker there was required.

When the repeat section is moved in units of 1 bar or 2 bars, the two markers at both ends of the repeat section are erased, and the marker is set by moving to the start position and end position of a new repeat section. An operation of re-performing was required, and a very complicated operation was required. In addition, even if you want to move any of the markers in meaningful units such as beats or bars, you can delete the marker you want to move, move it to a new position, and set the marker there again. This required a complicated operation.

The present invention has been made in view of such a problem, and an object of the present invention is to enable an automatic performance device to move a marker to a desired position with a small number of operations.

FIG. 4 illustrates a marker with a music symbol used in the present embodiment. For example, FIG.
In the case of a musical score in which the first and second measures are repeated as in (1), in the actual performance data, the repeated portion is played twice. When a musical score is arithmetically generated from the performance data, a repeated symbol or the like is not displayed as shown in FIG.
There is a problem that it differs from the example of (1) and that it is difficult to take measures. In this case, it is conceivable that a mark such as a repetition symbol is added to the musical score generated by calculation later. At the same time, since the position of such repetition is a break point for practice, a marker is often set.

Therefore, as shown in FIG. 4 (3), by putting a mark of a music symbol on the marker, the music symbol can be inputted as a mark at the same time as the marker is inputted. For this reason,
The visibility of the music is improved. The marker with the music symbol may be designed so that the music symbol is drawn on a five-line staff as shown in FIG.

FIG. 8 shows the types of music symbols of the markers as described above and the variables indicating the types. In this example,
As the types of music symbols set on the markers, those having designs as shown in FIG. 8 are prepared. This is designated by the number of the type number designation switch 21 when in the type mode, and is stored in a marker type Mkty which is a register described later. The initial value of the marker type Mkty is “1”. Markers A, B, C, and D corresponding to the marker numbers are displayed at positions A in the figure.

FIG. 6 shows variables relating to the mode switches 13 to 18. The mode switches 13 to 18
Register Mds whose N / OFF state is distinguished by a subscript
w. Further, depending on the mode of the switch being pressed, the mode number Mdnum is changed from “0” to “6”.
Is set. The initial value of the mode number Mdnum is “0”.

FIG. 7 shows variables relating to the marker switches 1-4. Marker switches 1-4 are ON / OFF.
The OFF state is read into a register MkSw distinguished by a subscript. Further, the value of “1” to “4” is set to the marker number Mknum by the pressed switch. The position set for each marker A, B, C, D
The type set for each of the markers A, B, C, and D is stored in the marker position Pos distinguished by the subscript, and is stored in the marker type Mkty distinguished by the subscript. The initial value of the value of each marker position Pos is that Pos (1) is “0” (= the start position of the song = the start position of the first bar), Po
s (2) is the start position of the second measure (= end position of the first measure), and both Pos (3) and Pos (4) are “−1”. Note that "-1" means that no marker has been set.

First, a method of moving a marker in the apparatus of this embodiment will be schematically described with reference to FIG. Although the operation method here describes the most orthodox one, other than described here, the same marker movement can be performed by operating the switch group in another mode. .

1. FIG. 1 (1) When the user proceeds with the practice, first, the first measure I is repeatedly practiced. Therefore, the markers A and B are set at the beginning and end of the first bar by the marker move operation.
When the apparatus is in the initial state, the markers A and B are set at the beginning and end of the first bar.
No settings are required.

2. FIG. 1 (2) Next, the user moves to the next second bar by a marker shift operation to practice. Therefore, the markers A and B are moved to the beginning and end of the next second bar. This operation is performed by pressing the marker shift R switch 12.

3. FIG. 1 (3) Next, the marker A is jumped forward, and the first and second
Practice bars. Therefore, the marker A is moved to the beginning of the first bar. This operation is performed by pressing the marker switch 1 for specifying the marker A while the marker jump L switch is pressed.

4. FIG. 1 (4), FIG. 1 (5) Next, from the marker shift, move to the next two measures, jump the marker B forward, and practice the third measure. As a method of this operation, first, the marker shift R switch 12 is pressed and moved to the right while maintaining the section length of the markers A and B. That is, the marker A is moved to the beginning of the third measure, and the marker B is moved to the end of the fourth measure. Next, with the marker jump L switch 13 pressed, the marker switch 2 for specifying the marker B is pressed. As a result, the marker A moves to the beginning of the third bar.

5. FIG. 1 (6) Next, the fourth measure is practiced by the marker shift operation. This operation is performed using the marker shift R switch 12
By pressing, the markers A and B are moved to the right while maintaining the section length. That is, the marker A moves to the beginning of the fourth measure, and the marker B moves to the end of the fourth measure.

6. FIG. 1 (7) Next, the marker A is jumped forward, and the third and fourth measures are practiced. This operation is performed by pressing the marker switch 1 for specifying the marker A while the marker jump L switch 13 is pressed. As a result, the marker A moves to the beginning of the third bar.

7. Fig. 1 (8) Finally, the marker A is jumped forward, and from the 1 bar, 4
Practice up to the bar. This operation is performed by pressing the marker switch 1 for specifying the marker A while the marker jump L switch 13 is pressed. This allows marker A
Moves to the beginning of the first measure.

As described above, since the operation in which the markers A and B had to be reattached in the past was completed in one or two operations, the operability is remarkably improved.

The operation of this embodiment will be described below with reference to the flowcharts of FIGS. The variables used in these flowcharts include the variables relating to the mode switch [register Mdsw (i), mode number Mdnum], and the variables relating to the marker switch [register Mksw (i), marker number Mksw, position Po.
s (i), marker type Mkty (i)], and the following.

Other variables TyMod: "1" when in type mode, initial value is "0" Dmp: "1" when instructing mute processing of sound currently being played, initial value is "0" Cur: Current playing position (clock), initial value is “0” Rep: “1” in repeat state, initial value is “0” RepSt: repeat start position (clock), initial value is “0” (= start of music) RepEnd: Repeat end position (clock), initial value is Base × Beat (= Start of second measure = End of first measure) DispSt: Start position of musical score display (Clock),
The initial value is “0” (= the beginning of the song). DispEnd: End position of the score display (clock),
Initial value is MeasL (= score display range) MeasL: range for displaying music (clock) SongEnd: end position of the music (clock) Base: length corresponding to the denominator note of the time signature of the music (clock) Beat: music Number of beats of Move: Unit for moving marker (cloc)

First, the main routine of the present invention will be described with reference to FIG. When the apparatus power is turned on, a main routine is started, and first, an initialization process is performed (step A1). In this initialization processing, the performance information of the music is read, and the end position SongEnd, base Bass of the music are read.
e, beat Beat, and score display range MeasL
(Corresponding to a clock for 4 bars) is set. Also, note type data is calculated and generated from the note length data. Other variables are set to the initial values described above. Further, the position Pos (1) of the marker A is set to RepSt, and the position Pos (2) of the marker B is set to RepSt.
Set to End. As a result, the markers A and B are set with the beginning and end of the first measure as initial values.

After initialization is completed, type mode TyM
It is determined whether or not “od” is “1” (step A2).
If "1", the current mode is the type mode. In this case, the type is set for the marker (step A).
13-A17). This processing will be described later.

When the type mode TyMod is "0",
The current mode is not the type mode. In this case, a score display process is performed on the display screen 5 (step A3). In this score display processing, as described later, 5 is displayed on the display screen 5.
Display notation, bar lines, clef, notes and rests, and display markers.

Thereafter, it is determined whether or not the play switch 6 is ON (step A4). If the play switch 6 is ON, a tempo clock interrupt is permitted to perform the music automatically (step A5). When this tempo clock interruption permission is performed, a tempo clock interruption process described later is periodically executed, and the automatic performance of the music is started.

Next, it is determined whether or not the stop switch 7 is ON (step A6). If the stop switch 7 is ON, the tempo clock interrupt is prohibited to stop the automatic performance of the music (step A7). When this tempo clock interrupt prohibition is performed, the tempo clock interrupt processing is not executed, the sound being generated is muted, and the automatic performance of the music is stopped.

Further, it is determined whether or not the repeat switch 8 is ON (step A8). If "ON", steps A9 to A11 are executed. This step A9 to A11
Implements a toggle operation of the repeat switch 8 and determines whether the repeat Rep is already "1", that is, whether the repeat switch is in the repeat state (step A9). If the repeat state is in the repeat state, the repeat Rep is set to "0" to repeat the operation. The state is released (step A10). If the state is not "0", that is, if the state is not the repeat state, the repeat state is set by setting the repeat Rep to "1", and the performance sound is interrupted by setting the mute Dmp to "1". The current position Cur is set to the beginning RepSt-1 of the repeat (step A1)
1). The operation of “−1” is an operation for achieving consistency of the operation. Thus, when the repeat state is reached during the performance, the performance sound is temporarily turned off, and a new performance is started from the repeat start position RepSt.

Next, a marker switch process is performed (step A12). The marker switch process is a routine for performing a marker process according to the settings of the marker switches 1 to 4, and will be described later in detail.

On the other hand, if the type mode TyMod is "1", that is, the marker type is selected in the determination in step A2, the type and number of the marker shown in FIG. The user is prompted to select a type (step A13). Further, it is determined whether or not the EXT switch 22 has been pressed while the marker type is being selected (step A14). If the EXT switch 22 has been pressed, the type mode TyMod is set to "0" to interrupt the processing (step A17). Get out of. If the EXT switch 22 has not been pressed (step A14), it is determined whether or not the number switch 21 is ON (step A15).
Loop between 14 and wait. When any one of the number switches 21 is pressed, a number is set to a marker type Mkty (Mknum) having a marker number Mknum set in a marker switch processing routine described later (step A16), and the type mode TyMod is set.
Is set to "0" (step A17) to exit the type mode.

Next, the above-described musical score display processing routine is shown in FIG.
This will be described with reference to the flowchart of FIG. When the musical score display processing routine is started, the musical score display start position DispS
From t, a musical score, a bar line, a clef, etc. are displayed from the musical score display end position DispEnd (step B1).
Then, a loop variable i (clock) of the display clock is initialized to the score display start position DispSt (step B2). The loop variable i of the display clock indicates the current position where the display processing is being performed by the number of clocks.

If there is performance data at the display position indicated by the loop variable i, a note is displayed at that position (step B).
3). The display position is specified by associating the pitch of the performance data described above with the vertical position on the staff notation and the sounding timing with the horizontal position, and displaying the note specified by the note type at that position. I do. If a rest is necessary in relation to the previously displayed note, this is also displayed.

Next, a loop variable j corresponding to the marker number is initialized to "1". This loop variable j is
“1” indicates marker A, “2” indicates marker B, “3”
Represents the marker “C”, and “4” represents the marker D. When the marker position Pos (j) of the marker specified by the marker variable j is equal to the loop variable i of the display clock, the marker is displayed at the display position indicated by the loop variable i (step B6). In the marker display processing, the marker of the marker number j is set to a marker type Mkty at a predetermined position above the five staffs at the position of the display clock.
(J) is displayed.

If the marker position Pos (i) is not equal to the loop variable i, or if the marker is displayed in step B6, the loop variable j of the marker number is incremented by one (step B7), and the value becomes "4". It is determined whether all of the four markers A, B, C, and D have been displayed based on whether or not the display has reached (step B8). If "4" has not been reached, there is a marker for which the presence / absence of marker display has not yet been checked among the four markers A, B, C, D, so that the processing from step B5 is repeated. on the other hand,
If "4" has been reached (step B8), marker A,
This means that the presence / absence of marker display has been checked for B, C, and D. In this case, the loop variable i is incremented by one, and it is determined whether or not the incremented loop variable i has reached the musical score display start position DispEnd (step B10). For the display position indicated by the loop variable i, the processing from step B3 onward is repeated.
If the loop variable i has reached the musical score display start position DisplEnd, it means that all the performance data and the presence / absence of markers in the section to be displayed have been checked, and the process returns.

Next, the tempo clock interrupt processing will be described with reference to the flowchart of FIG. This tempo clock interrupt processing routine is started at the timing of each clock according to the tempo by the tempo clock interrupt generated by the tempo clock unit 36 when the tempo clock interrupt is permitted in the main routine. For example, in the case of a quarter note, the quarter note corresponds to 96 clocks, and this routine is started for each clock. In this tempo clock interruption processing routine, processing of sound generation processing and repeat, and processing of updating the musical score display as the automatic performance progresses are performed.

First, the current performance position Cur is incremented by one (step C1). Then, repeat Re
It is determined whether or not p is "1" (step C2). "0"
That is, if it is not in the repeat state, the current playing position Cu
It is determined whether r has reached the end position SongEnd of the music (step C3).
The tempo clock interrupt is prohibited (step C4), and the automatic performance is stopped. If the song end position SongEnd has not been reached (step C3), step C described later
The program proceeds to step 7 and thereafter to continue the automatic performance.

If the repeat Rep is "1", that is, the repeat state (step C2), the current performance position Cur
Is determined to have reached the repeat end position RepEnd (step C5). If it has reached, the process returns to the start position of the repeat section to perform an update process for performing a repeat performance (step C6). Specifically, Step C6
In the processing of, the current performance position Cur is returned to the repeat start position RepSt, the score display start position DispSt is similarly returned to the repeat start position RepSt, and the score display end position DispEnd is separated from the repeat start position RepSt by the score display range MeasL. At the selected position, that is, DispEnd ← RepSt + MeasL, and the mute Dmp is set to “1” in order to instruct the mute of the sound generated at the repeat end position RepEnd.

When the updating process is completed (step C
6) Alternatively, if it is determined that the music is not in the repeat state and that the song has not reached the end position SondEnd (step C3), the process proceeds to step C7 and continues the automatic performance. First, it is determined whether or not the mute Dmp is “1” (step C7). This silence Dmp is set to "1" when the performance position Cur reaches the repeat end position RepEnd, when a marker is instructed to jump to another position, and the like, and instructs silence at the current position. "1"
If so, mute the currently sounding sound and mute Dm
By setting p = 0, the mute is completed.

Next, it is instructed to sound at the current performance position Cur (step C9), and it is determined whether or not the current performance position Cur exceeds the musical score display end position DispEnd (step C10). And returns to end the tempo clock interrupt process in the current clock cycle. If it exceeds, the musical score display is updated (steps C11 to C13). In this update process,
The score display range M is set at the current score display start position DispSt.
easL is added to the new score display start position Dis
pSt, and a new score display end position DispEnd is obtained by adding the score display range MeasL to the current score display end position DispEnd. Further, the updated score display end position DispEnd is the song end position SongE.
nd is determined (step C12).
If it has reached, the musical score display end position DispEnd is set to the song end position SongEnd (step C13). After these processes, the process returns to end the tempo clock interrupt in the current clock cycle.

Next, the marker switch processing routine will be described in detail below with reference to the flowcharts of FIGS. In this marker switch processing routine, the ON / OFF states of the marker switch groups 1 to 4 and 11 to 20 are checked, and a marker operation is performed in accordance with those states. A jump process, a change operation of a repeat section designated by the markers A and B, a set process of the markers C and D and a jump process of a performance position and the like are performed.

First, in the flowchart of FIG. 12, the states of the mode switches 13 to 18 and the move unit designating switches 19 and 20 are detected. That is, when the marker switch process is started, it is determined whether or not the major (M) switch 19 is ON (step D1). If the switch is ON, the unit Move of the marker move is changed to the base Bas.
Set to e × beat Beat (step D2). This corresponds to the length of one bar. On the other hand, major switch 1
If 9 is OFF (step D1), it is determined whether the beat (B) switch 20 is ON (step D3) and ON.
Then, the unit Move of the marker move is set to the base Ba.
Set to se (step D4). This is equivalent to the length of one beat.

Thereafter, the mode number Mdnum is set to "0".
Then, the loop variable i of the mode number is initialized to "1" (step D5). Next, it is determined whether or not the i-th mode register Mdsw (i) is ON (step D).
6) If it is OFF, or immediately if it is ON, after setting the loop variable i to the mode number Mdnum (step D7), the loop variable i is incremented by one (step D8), and the incremented loop variable i becomes "6". It is determined whether or not it has exceeded (step D9).
If it exceeds “6”, it means that the ON / OFF state check has been completed for all of the mode switches 13 to 18. Therefore, if it is equal to or less than "6", the process returns to step D6 and the subsequent steps are repeated. Thus, the mode number Mdnum is set to the number corresponding to the ON switch among the mode switches 13 to 18.

After all mode switches have been checked, the processing is changed as follows according to the operation state of the marker switch group. First, shift switches 11 and 12
The operation performed when is operated will be described with reference to the flowchart of FIG.

In FIG. 13, shift switches 11, 1
It is determined whether or not 2 has been turned on (step E0).
If N, the following shift processing is performed. In the shift processing, the repeat section delimited by the markers A and B is moved by the section length dist in the form of a parallel movement to the right or left on the musical score while maintaining the section length dist.

First, it is determined whether or not the reverse rev is "1" (step E1). When the reverse rev is “1”, the front and rear of the markers A and B are reversed and the marker B is reversed.
Is on the left side (front side) on the score. The temporary positions Pos1 and Pos2 are set as follows according to the state before and after the markers A and B. The temporary positions Pos1 and Pos2 are names of temporary registers used for performing the shift processing. When the reverse rev is “0”, the position Pos (1) of the marker A is set to the temporary position Pos1, and the temporary position Pos2 is set.
Is set to the position Pos (2) of the marker B (step E2), and when the reverse rev is “1”, the position Pos1 of the marker B is set to the temporary position Pos1.
(2), and the position Pos (1) of the marker A at the temporary position Pos2 (step E).
3). This processing is for treating the front marker position as Pos1 and the rear marker position as Pos2 in the repeat section.

Next, the marker shift switches 11, 1
It is determined which of the two has been turned ON. That is, the marker shift R switch 12 for right shifting
Is determined to be ON. If it is ON, that is, right shift, it is determined whether or not the rear marker position Pos2 of the repeat section exceeds the end position SongEnd of the song (step E9). If not, the rear marker position Pos1 is set to the front marker position Pos1. The position Pos2 is set, and the section length dist is added to the rear marker position Pos2 (step E10). As a result, the entire repeat section is shifted rightward by the section length dist. Furthermore, the rear marker position Pos2 after the shift is the end position Son of the music.
It is determined whether or not gEnd has been exceeded (step E11). If it has, the end position SongEnd of the song is set to the rear marker position Pos2 (step E12). On the other hand, if the rear marker position Pos2 before the shift has already exceeded the end position SongEnd of the music (step E
9) Since right shift is impossible, the above-mentioned step E1
Steps 0 to E12 are not performed.

On the other hand, when the marker shift R switch 12 is
FF (that is, the marker shift switch 11 is ON)
If (step E4), this is a left shift. In this case, it is determined whether or not the front marker position Pos1 of the repeat section is before the head position “0” of the music (step E).
5) If not before, the front marker position Pos1 is set to the rear marker position Pos2, and the front marker position P
The section length dist is subtracted from os1 (step E
6). Thereby, the repeat section is shifted to the left by the section length dist as a whole. Further, it is determined whether or not the front marker position Pos1 after the shift is before the head position “0” of the music (step E7). If it is before, the head position “0” of the music is set to the front marker position Pos1 (step E7). Step E8). On the other hand, if the front marker position Pos1 before the shift is already before the head position “0” of the music (step E
5) Since the left shift is impossible, the above step E6
Steps E8 to E8 are not performed.

Thereafter, the start position RepS of the repeat section
The front marker position Pos1 is set to t, and the rear marker position Pos2 is set to the end position RepEnd of the repeat section.
Is set (step E16). And reverse re
It is determined whether or not v is "1" (step E13). According to the result, the contents of the temporary positions Pos1 and Pos2 updated by right shift or left shift are updated to the marker positions Pos (1) and Pos (2). Write back to That is,
If the reverse rev is “0”, the marker position Pos
(L), Pos (2) at temporary position PoS1, P
os2 is written back (step E14), and if the reverse rev is “1”, the marker position Pos
(1), Pos (2) at temporary position Pos2, P
os1 is written back (step E15), and the process returns.

On the other hand, when the operated switches are not the shift switches 11 and 12 (step E0),
As shown in FIG. 17, processing when marker switches 1 to 4 are used in combination with mode switches 13 to 18 is performed. Here, FIG. 14 is a flowchart mainly illustrating the set and jump processing relating to the markers C and D, and FIG. 15 is a flowchart mainly illustrating the jump processing and move processing relating to the markers A and B.
FIG. 17 is a flowchart mainly explaining the enlargement / reduction processing of the repeat section related to the markers A and B.

First, in FIG. 14, after the loop variable j of the marker number is initialized to "1" (step F
0), the j-th marker switch Mksw (j) is ON
Is determined (step F1), and if not ON, M
kon (j) is cleared to "0" (step F2).
This Mkon (j) is a variable for detecting a change when the marker switch is turned on. If the marker switch Mksw (j) is ON, it is determined whether or not Mkon (j) is "1" (step F3).
If (j) is already "1", the marker switch is not newly pressed, so the loop variable j is incremented by one to check the state of the next marker switch (step F4). ). If Mkon (j) is not “1”, since the marker switch has been newly pressed, “1” is set in Mkon (j) (step F4), and the process proceeds to step F5 and subsequent steps. As described above, the processing of steps F1 to F3 is equivalent to the processing of step F5 and subsequent steps.
This is to execute it only once for the ON operation of the marker switch.

If it is determined in step F3 that the marker switch has been newly pressed, the mode number Mdnum
Is "6" indicating the marker type mode.
If "6", that is, the marker type mode is specified, the marker type mode is entered. Therefore, "1" is set in the type mode TyMod, and the marker number Mkn is set.
A loop variable j is set in um (step F6), and the routine returns. With this processing, the processing of the marker type mode is performed in the main routine as described above.

If the mode number Mdnum does not indicate the marker type mode (step F5), it is determined whether the loop variable j of the marker number is "1" or "2" (step F7). This is to determine whether or not the marker A or B is designated by the marker switch 1 or 2. In the case of the marker A or B, the process proceeds to the processing of the flowchart of FIG. If it is not marker A or B, marker C or D is designated. In this case, the processing for the marker C or D is executed. First, it is determined whether or not the mode number Mdnum is “5” that specifies the marker clear mode (step F).
8) If marker clear mode is specified,
The position "Pos (j)" of the marker is set to "-1" meaning clear (step F9), and the setting of the marker C or D is released.

On the other hand, if the marker clear mode has not been designated (step F8), the mode number Mdnu
It is determined whether or not m is “0” indicating that none of the mode switches 13 to 18 is operated (step F1).
0). If it is not “0”, that is, even if any one of the mode switches 13 to 18 is operated, none of the modes of the markers C and D function.
The process goes to Step F14 for updating the loop variable j.

When none of the mode switches 13 to 18 is operated, as described above, the markers C and D are used for the marker switches 3 and 4 of the markers C and D.
Is pressed, the marker C or D is set at the current playing position if the marker C or D has not been set. If the marker C or D has already been set, the current playing position is jumped to the set marker position. Perform the operation.
Therefore, it is determined whether or not the position Pos (j) of the marker C or D is “−1” meaning clear (step F1).
1) If clear, that is, if the marker has not been set, the current performance position Cur is set to the position Pos (j) (step F13). If the marker has already been set (step F11), the position Pos (j) is set at the current performance position Cur.
Is set, and the position P is set at the head position DispSt of the score display.
os (j) is set, and the end position DispS of the score display is set.
A value obtained by adding the position Pos (j) and the musical score display range MeasL to t is set, and “1” is set to the mute Dmp to instruct the mute processing of the sound currently being generated (step F14). As a result, both the performance position and the display position jump to the already set marker C or D position.

Thereafter, the loop variable j is incremented (step F14), and it is determined whether or not the processing of all the marker switches has been completed (step F15). If the processing has not been completed, the process returns to step F1. This processing is also performed when the flow of FIGS. 15 and 16 described later ends.

Next, the processing in the case where it is determined in step F7 that the marker switches 1 and 2 corresponding to the markers A and B have been operated will be described with reference to the flowcharts of FIGS. First, the flowchart of FIG. 15 will be described. The processing in FIG.
For B, the mode numbers Mdnum are “0”, “5”,
"4", "3", that is, processing when the mode switch is not pressed, in the clear mode, or in the moving mode.

First, it is determined whether or not the mode number Mdnum is "0" which means no operation of all the mode switches 13 to 18 (step G1). All mode switches 13-18
Is operated, the markers A and B perform an operation of jumping the current performance position to the set marker position. Therefore, the position Pos is placed at the current performance position Cur.
(J) is set, the position Pos (j) is set at the head position DispSt of the score display, and the end position Di of the score display is set.
The position Pos (j) and the score display range Meas at spEnd
A value obtained by adding L is set, and "1" is set in the silence Dmp to instruct a silencing process of the sound currently being sounded (step G3). As a result, both the performance position and the display position jump to the already set marker A or B position.

If it is determined that any one of the mode switches 13 to 18 is operated (step G1), the mode number Mdnum is set to "4" which designates the marker move R mode for moving the marker A or B to the right. It is determined whether or not there is (Step G6). In the marker move R mode, the current position Pos of the marker A or B is set.
By adding the movement unit Move to (j), the marker A or B is moved to the right of the score (toward the back of the music piece) (step G7). Then, as a result of the movement, the marker A or B
It is determined whether or not the position Pos (j) has exceeded the end position SongEnd of the song (step G8). If it has, the position Pos (j) of the marker A or B is set as the end position SongEnd of the song. (Step G9).

On the other hand, if the mode is not the marker move R mode (step G6), the mode number Mdnum is set to the marker A
Alternatively, it is determined whether or not the value is “3” for specifying the marker move L mode for moving B to the left (step G1).
0). In the case of the marker move L mode, the movement unit Move is performed from the current position Pos (j) of the marker A or B.
Is subtracted to move the marker A or B to the left of the musical score (in the forward direction of the music) (step G11). Then, as a result of the movement, it is determined whether or not the position Pos (j) of the marker A or B is before the head position "0" of the music (step G12). The position Pos (j) of B is set to the head position "0" of the music (step G13).

When the jump processing and the movement processing of the marker A or B are completed, since the position of the marker A or B has been changed, the related variables are updated (steps G3 to G5). That is, the position Pos of the markers A and B
Compare the magnitudes of (1) and Pos (2) (Step G
3) Check which of the markers A and B precedes.
If the markers are in the order of A and B, the reverse rev is set to “0” and the repeat section length dist is set to “Pos
(2) -Pos (1) ", and set the position Pos of the marker A at the beginning position RepSt of the repeat section.
(1) is set, and the end position RepEn of the repeat section is set.
The position Pos (2) of the marker B is set to d (step G5). On the other hand, if the markers are in the order of B and A, the reverse rev is set to “1” and the repeat section length di
st is obtained and set by “Pos (1) −Pos (2)”, the position Pos (2) of the marker B is set to the head position RepSt of the repeat section, and the position Pos of the marker A to the end position RepEnd of the repeat section. (1) is set (step G4).

On the other hand, when the mode number Mdnum does not designate a move mode, the processing of the marker jump mode shown in the flowcharts of FIGS. 16 and 17 is executed. In this jump processing, when a marker A or B ahead of the repeat section is instructed to jump forward, the marker A or B is located at a position where the distance between markers (section length) is doubled. When the user jumps and is instructed to jump backward, the player jumps to a position where the distance (section length) between the markers becomes half. On the other hand, if the marker B or A behind the repeat section is instructed to jump forward, the marker jumps to a position where the distance between the markers (section length) is halved, and jumps backward. When the instruction is given, the position jumps to a position where the distance (section length) between the markers is doubled.

First, it is determined whether or not the mode number Mdnum is “2” which designates a marker jump R mode for making the marker A or B jump rightward (step H1). "2" for marker jump R mode, "2"
Otherwise, it is the marker jump L mode in which the marker A or B jumps to the left.

In the marker jump R mode, there are the following four ways of jumping the marker A or B. (1) Jump right at marker A in front of the repeat section,
Fix the rear marker B. That is, the repeat section is reduced in a state where the order of the markers is A and B. (2) The marker B on the front side of the repeat section is fixed, and the marker A on the rear side is jumped to the right. That is, the repeat section is extended when the order of the markers is B and A. (3) The marker A on the front side of the repeat section is fixed, and the marker B on the rear side is jumped to the right. That is, the repeat section is expanded in a state where the order of the markers is A and B. (4) Jump right at marker B in front of the repeat section,
The rear marker A is fixed. That is, the repeat section is reduced when the order of the markers is B and A.

On the other hand, in the marker jump L mode, there are the following four ways of jumping the marker A or B. (5) Jump the marker A at the front of the repeat section to the left,
Fix the rear marker B. That is, the repeat section is extended in a state where the order of the markers is A and B. (6) The marker B on the front side of the repeat section is fixed, and the marker A on the rear side is jumped to the left. That is, the repeat section is reduced when the order of the markers is B and A. (7) The marker A on the front side of the repeat section is fixed, and the marker B on the rear side is jumped to the left. That is, the repeat section is reduced in a state where the order of the markers is A and B. (8) Jump the marker B at the front of the repeat section to the left,
The rear marker A is fixed. That is, the repeat section is expanded in a state where the order of the markers is B and A.

In FIGS. 16 and 17, the above (1)
The same flow path (1) to (8)
(8) is assigned and associated. Hereinafter, these processes will be described in detail.

When the mode is determined to be the marker jump R mode (step H1), it is determined whether or not the loop variable j is "1", that is, whether the processing target is the marker A or B (step G1).
2) If it is a marker A, it is determined whether the marker A is before or after the repeat section by checking whether the reverse rev is “1” (step H3). If the reverse rev = 0, the processing of the marker A before the repeat of the above (1) is performed, and the position Pos (1) of the marker A is set to the current interval d.
advance to the right side position by half of ist (step H4),
Halves the repeat section. The division is rounded to an integer.

If reverse rev = 1, the above (2)
, The position Pos (1) of the marker A is advanced to the right position by the current interval dist (step H5), and the repeat section is doubled. As a result of the right jump of the marker A, it is determined whether or not the position Pos (1) exceeds the end position SongEnd of the song (step H6). If the position Pos (1) exceeds the end position, the end position SongEnd of the song is set to the position Pos (1). Set (step H7).

On the other hand, if it is determined in step H2 that the processing target is the marker B, it is determined whether the marker B is on the front side or the rear side of the repeat section based on whether the reverse rev is "1" (step H8). ). If the reverse rev = 0, the processing of the marker B on the rear side of the above-mentioned (3) is performed, and the position Pos (2) of the marker B is set to the current interval d.
The position is advanced to the right position by ist (step H9), and the repeat section is doubled. As a result of the marker B jumping to the right, the position Pos (2) becomes the end position So of the music.
It is determined whether or not ngEnd has been exceeded (step H10). If it has, the end position of the song Son is added to the position Pos (2).
gEnd is set (step H11).

On the other hand, in step H8, reverse rev = 1
If so, the marker B on the front side of the repeat in (4) above
Is performed, the position Pos (2) of the marker B is advanced to a position on the right side by half the current interval dist (step H).
12) Make the repeat section half of the current one. The division is rounded to an integer.

On the other hand, if it is determined in step H1 that the mode is the marker jump L mode, it is determined whether or not the loop variable j is "1", that is, whether the processing target is the marker A or B (step G13). If reverse
It is determined whether or not the marker A is the front side or the rear side of the repeat section based on whether or not ev is “1” (step H14). If the reverse rev = 0, the processing of the marker A before the repeat in the above (5) is performed, and the position Pos of the marker A is set.
(1) is returned to the left position by the current interval dist (step H5), and the repeat section is doubled.
As a result of the marker A jumping to the left, the position Pos
It is determined whether (1) is before the head position "0" of the music (step H16).
The head position "0" of the music is set to s (1) (step H17).

In step H14, reverse rev =
If it is 1, the processing of the marker A on the rear side of the above-mentioned (6) is performed, and the position Pos (1) of the marker A is returned to the position on the left side by half the current interval dist (step H4), and the repeat section To half of current. The division is rounded to an integer.

On the other hand, if it is determined in step H13 that the processing target is the marker B, the reverse rev is set to “1”.
It is determined whether or not the marker B is before or after the repeat section (step H19). If the reverse rev = 0, this is the processing of the marker B on the rear side of the above-mentioned (7), and the position Pos (2) of the marker B is returned to the left side position by half of the current interval dist (step H2).
0), the repeat section is halved from the current half. The division is rounded to an integer.

On the other hand, in step H19, the reverse r
If ev = 1, the processing of the marker B before the repeat in the above (8) is performed, and the position Pos (2) of the marker B
Is returned to the left position by the current interval dist (step H21), and the repeat section is doubled. It is determined whether or not the position Pos (2) is located before the head position “0” of the song as a result of the marker B being jumped to the left (step H22).
Is set to the beginning position of the song (step H2).
3).

When the processing of steps H1 to H23 is completed, the positions of the markers A and B are changed. Therefore, a new marker interval dist is calculated, and the start position RepSt and the end position RepEnd of the repeat section are set ( Steps H24 to H26). That is, the order of the markers A and B is determined based on whether or not the reverse rev is “1” (step H24). If the marker A is set after B, “Pos” is set in the marker interval dist.
(1) -Pos (2) "is set, and Pos (2) and Pos (1) are set at the start position RepSt and end position RepEnd of the repeat section, respectively (step H26). When the marker A is set before B, the marker interval dist is set to “Pos
(2) -Pos (1) "is set, and Pos (1) and Pos (2) are set at the start position RepSt and the end position RepEnd of the repeat section, respectively (step H25).

In implementing the present invention, various modifications other than those described above are possible. For example, in the above-described embodiment, the marker shift moves the repeat section so that a new repeat section comes before or after the previous repeat section. However, the present invention is not limited to this. Alternatively, the markers A and B before and after the repeat section may be moved in beat units. In this case, it is preferable to provide a setting means for setting the movement amount, and to move by the set movement amount.

Further, in the above-described embodiment, the expansion or reduction of the repeat section in the marker jump mode is set to twice the current repeat section in the case of enlargement, and to one half of the current repeat section in the case of reduction. However, the present invention is not limited to this, and the amount of enlargement or reduction is arbitrary,
For example, the size may be set to be an integral multiple in the case of enlargement, and set to a fraction of an integer in the case of reduction.

In the above-described embodiment, the expansion or reduction of the repeat section in the marker jump mode is instructed by using the jump switches 13 and 14 and the marker switches 1 and 2 for specifying the markers A and B. However, the present invention is not limited to such a switch arrangement. Alternatively, a reduction instruction operator for instructing reduction is provided to the rear side, and when expansion to the front is instructed by the expansion instruction operator, the marker on the front side of the repeat section is set to the front side, and the expansion to the rear side is performed. When instructed, the marker on the rear side of the repeat section is moved to the rear side. The rear side over, or may be caused to the mobile side of the marker after the repeat section on the front side in the case of reduction to the front is instructed.
