Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device, an automatic performance program, and a data structure of automatic performance data capable of jumping to an arbitrary position in music data and performing loop reproduction of an arbitrary section.

[0002]

2. Description of the Related Art It is possible to instantly jump to a corresponding bar by setting a desired bar in music data to each of a plurality of switches provided on an operation panel of an automatic performance device and operating each switch. Automatic playing devices are known. For example, the automatic performance device described in Japanese Patent Application Laid-Open No. 09-114456 is capable of setting information such as a song number and the number of measures to each switch, and when any switch is operated. On the other hand, it is designed so that it will automatically play by jumping to the bar set for that switch.

[0003]

However, in the conventional automatic musical performance device capable of jumping to the corresponding measure by operating the switch, the desired measure set in each switch is stored in the automatic musical instrument main body. It is made to be remembered. Therefore, when the song data is changed, the jump during automatic performance cannot be controlled, and when the automatically played song data is changed, it is necessary to reset each switch. There was a point. Moreover, the setting to each switch is made in units of measures, and there is a problem that it cannot be set in units of non-measures.

Therefore, the present invention provides an automatic performance device, an automatic performance program, and a data structure of automatic performance data which can easily perform a jump to an arbitrary position in music data and a loop reproduction of an arbitrary section. The purpose is to do.

[0005]

In order to achieve the above object, the automatic performance device of the present invention comprises an automatic performance means for reading and automatically playing music data, and the music data when the music data is loaded. In the song data, a detecting means for detecting a song position marker indicating a specific performance position in the song data, and when the automatic playing means is automatically playing the song data, one of the song position markers is designated. At this time, the performance position of the designated song position marker is jumped to and automatically played by the automatic performance means.

Further, in the above-mentioned automatic performance device of the present invention, the song position marker is assigned to any one of the plurality of switch means, and any one of the switch means is operated to be assigned to the operated switch means. The song position marker may be designated. Further, in the above-mentioned automatic performance device of the present invention, the song position marker is capable of designating a specific performance position of the song data in non-measure units, and when the song position marker is designated, it is designated. When the automatic playing is performed up to the position within the bar that corresponds to the playing position of the specified song position marker that will be reached next to the automatically playing position when the playing position of the specified song position marker is reached, You may make it jump and be played automatically.

Furthermore, in the above-mentioned automatic performance device of the present invention, after the song position marker is designated, the position of the automatic performance is waiting for a jump to reach the position within the next bar to be reached. When the same song position marker is designated again, the jump may be canceled. Furthermore, in the above-described automatic performance device of the present invention, a loop end marker indicating a loop end position during loop reproduction can be set in the music data, and when loop reproduction is instructed, the song position marker is set. Alternatively, when the song is automatically played to the position of the loop end marker, it jumps to the song position marker located before it and loops between the first song position marker or loop end marker located after the song position marker. It may be done.

Furthermore, in the above-described automatic performance device of the present invention, the song position marker may include loop count information, and loop reproduction may be performed for the number of loops at the jumped song position marker. Furthermore, in the above-mentioned automatic performance device of the present invention, the name of the marker may be given to the song position marker. Furthermore, in the above-mentioned automatic performance device of the present invention, song position information storage means for storing setting information corresponding to the performance position of the song position marker detected by the detection means,
Setting means for setting the playing position of the song position marker in non-measure units, and when setting the playing position of the song position marker, a setting corresponding to the playing position after setting of the song position marker Information may be stored again in the song position information storage means.

Furthermore, in the above-mentioned automatic performance device of the present invention, there is further provided setting means for setting the performance position of the song position marker and / or the loop end marker in non-measure units, and the performance position of the marker is set. In doing so, the time distance between the markers may not be set below a predetermined value. Furthermore, in the above-mentioned automatic performance device of the present invention, during automatic performance or loop reproduction, the display means assigned to the song position marker corresponding to the performance position displays that fact. Good.

Next, the data structure of the automatic performance data of the present invention which can achieve the above object is such that the event data for generating and controlling the musical tone and the timing data indicating the occurrence timing of the event data alternate. A data structure of automatic performance data which can be automatically played by an automatic performance device comprising at least a data sequence arranged in the event data, wherein the event data includes a song position marker indicating a specific performance position in the automatic performance data. At least one is included. Further, in the data structure of the automatic performance data of the present invention, the song position marker can be a loop start position or a loop end position during loop reproduction, and the event data includes a specific performance in the automatic performance data. A loop end marker indicating the position and serving as a loop end position during loop reproduction may be included. The automatic performance device of the present invention may be realized by an automatic performance program having the same function.

According to the present invention as described above, it is possible to insert a song position marker or a loop end marker, which indicates a specific performance position in the music data, into the music data. Therefore, when the song data is changed, the song position marker and the loop end marker are detected from the song data and automatically set. Therefore, even if the music data is changed, it is possible to easily perform a jump to an arbitrary position in the music data and a loop reproduction of an arbitrary section. Since a song position marker and a loop end marker can be inserted in the song data as event data, song position setting and loop end setting can be easily performed for each song data. The timing of the song position marker and the loop end marker can be set in non-measure units, for example, the number of measures, the number of beats, and the clock. In this case,
If the markers are too close to each other, it is meaningless to set them, and therefore it is preferable not to set them. When jumping to the specified song position marker, when the performance position reaches the in-measure position corresponding to the position of the specified song position marker, which is reached after the jump is specified, the specified song I try to jump to the performance position of the position marker. As a result, the user can jump without making the user feel uncomfortable.

Furthermore, since the loop end can be set by the loop end marker in addition to the song position during loop reproduction, the loop end can be set at any position other than the song position. Further, since the display means such as the LED is provided corresponding to the song position marker, it is possible to grasp which song position is currently being reproduced by the display means. Furthermore, since the name and the number of loops can be set for each song position marker, the song position can be easily understood and the loop playback can be freely controlled. If the switch means for instructing to jump to the song position is a toggle switch whose state is inverted each time it is operated, the instruction to jump to the song position can be easily canceled.

It is set as the number of loops during loop playback. Event data of the song position marker is general MI
It can be created and edited by a DI sequencer. If any of such song position markers SPJ-01 to SPJ-04 is specified during automatic performance in the automatic performance device 1 shown in FIG. 1, the performance position of the specified song position marker is jumped to. It will be played automatically. In order to realize such an operation, when the song data is loaded from the external storage device 14 or the like into the RAM 13, a song position marker in the song data is detected, and the contents and song described in the event data are detected. Setting information including the number of bars, the number of beats, the number of clocks, and the musical tone setting data effective at the position of the song position, which is obtained from the timing data of the position marker, is stored in the song position marker information storage area secured in the RAM 13. Four song position markers SPJ-01-S
An example in which PJ-04 is detected and its setting information is stored in the song position marker information storage area is shown in FIG.
Shown in.

The setting information of each song position marker stored in the song position marker information storage area shown in FIG. 4 is as follows. The first song position marker SPJ-01 having the song position number “01” has the number of measures “1” and the number of beats “1”, which is the first beat of the first measure at the beginning of the song data, and the clock. The number “000” is a song position, the name of the song position is “Intro”, the number of loops is “5”, and setting information is configured from setting data such as program change and control change. The second song position marker SPJ-02, which has the song position number “02”, has the bar number “16”, the beat number “2”, and the clock number “000” as the song position. Is "Choru
s ”, the number of loops is“ infinite ”, and setting information is configured from setting data such as program change and control change. The third song position marker SPJ-03, which has the song position number “03”, has the number of measures “8”, the number of beats “1”, and the number of clocks “000” as song positions. Is “Verse”, the number of loops is “infinite”, and setting information is configured from setting data such as program change and control change. Song position number "04"
Fourth song position marker SPJ-
04 is the number of measures "24", the number of beats "1", the number of clocks "0"
00 ”is a song position, the song position is not named, the number of loops is“ 2 ”, and setting information is configured from setting data such as program change and control change.

Then, the information in the song position information storage area is referred to, and each position marker is assigned to a song position switch constituting a part of the panel operator 22, respectively. In this case, the song position number and the song position switch number are assigned so as to correspond to each other. That is, when the information in the song position information storage area is as shown in FIG. 4, the first song position marker SPJ-01 is assigned to the first song position switch 31 shown in FIG. 2 song position marker SP
J-02 is assigned, and the third song position switch 33 has a third song position marker SPJ-03.
And the fourth song position marker SPJ-04 is assigned to the fourth song position switch 34. When one of the song position switches 31 to 34 is operated, the song position switch jumps to the performance position indicated by the song position marker assigned to the song position switch. When jumping, the song position marker is the position that corresponds to the position (beat, clock) indicated by that song position marker, and that will arrive next to the position that was being played when the song position switch was operated. By jumping from the position in the bar corresponding to the position shown by, the unnatural feeling is prevented from occurring as much as possible in the continuous automatic performance.

In the example shown in FIG. 3, the maximum number of song position markers is four. In this case, the song position numbers are “01” to “04” as shown in FIG. 4, but the order does not have to be the time position order, and the time position may be reversed. In addition, markers with other numbers become loop end markers that indicate loop ends. Further, in the notation of the song position marker shown in FIG. 3, the first ":" is a delimiter that indicates the delimiter between the song position number and the song position name, and the second ":" is the song position name and the loop count. Is a delimiter indicating the delimiter. If a song position name that can be an arbitrary character string is used for the notation of the song position marker, the user can easily identify the type of the marker. Furthermore,
The number of loops is the number of repetitions during loop reproduction. If this loop count is not specified, the loop will be infinite (repeated until loop playback is turned off).

Furthermore, as shown in FIG. 4, setting data such as program change and control change corresponding to the position of the song position marker is stored corresponding to each song position switch. As a result, when a jump or loop is performed, an appropriate program change, control change, or the like can be set at the position of each song position marker. As will be described later, when the marker position is edited and moved, the setting data is also corrected to correspond to the moved position.

More specifically, the jump from the position corresponding to the position indicated by the song position marker will be described with reference to FIGS. In FIG. 5, the position Tj of the song position marker assigned to the operated song position switch is set as the first beat (bar start) of the bar with a time signature of 4/4.
The position when the song position switch is operated at the first and a half beats of a bar with four beats is indicated by Tp1 and is 4/4.
The position when the song position switch is operated at the second and a half beats of the time signature is indicated by Tp2, and the position when the song position switch is operated at the first and a half beats of the 3/4 time measure is indicated by Tp3. ing. In this case, since the position Tj is the first beat, the song position switch is set to the position Tp1 or the position Tp.
When the operation is performed at 2, the jump is made to the position Tj from the first beat of the first bar thereafter, and the performance is automatically started. Although the time signature is changed at the position Tp3, when the song position switch is operated at the position Tp3, the beat is automatically played by jumping from the first beat of the first bar to the position Tj.

Next, in FIG. 6, the time signature is not changed and is set to 4/4, and the position Tj of the song position marker assigned to the operated song position switch is set to the second beat, which is 1 during automatic performance. The position when the song position switch is operated at the half beat is indicated by Tp1,
The position when the song position switch is operated at the second and half beats is indicated by Tp2. In this case, the position Tj
Since it is the second beat, when the song position switch is operated at the position Tp1, the song is automatically played by jumping to the position Tj from the second beat in the bar which is half beat later. When the song position switch is operated at the position Tp2, 2 in the next measure
From the beat, the position is jumped to the position Tj to be automatically played.

Next, in FIG. 7, the position Tj of the song position marker assigned to the operated song position switch is set to the second beat of the bar of 4/4 time, and the bar of 3/4 time is played during the automatic performance. The position when the song position switch is operated at the first and a half beats of is indicated by Tp1, and the position when the song position switch is operated at the second and a half beats of the 3/4 time bar is indicated at Tp2. In this case, since the position Tj is the second beat, when the song position switch is operated at the position Tp1, the second beat of the bar, which is half a beat later, is moved to the position Tj regardless of the change of the time signature. You can jump and play automatically. Further, when the song position switch is operated at the position Tp2, regardless of the change of the time signature, the second beat of the next bar is jumped to the position Tj to be automatically played.

Next, in FIG. 8, the position Tj of the song position marker assigned to the operated song position switch is the fourth beat and a half of the bar of 4/4 time,
The position when the song position switch is operated at the 1st beat and the 16th minute of the 3/4 bar during the automatic performance is Tp1.
The position when the song position switch is operated at the second and a half beats of the measure of 3/4 time is shown as Tp2, and the song position at the 1st and 16th minute of the next 3/4 measure. The position when the switch is operated is indicated by Tp3. In this case, the position Tj is the fourth and a half beats, and since the time signature has been changed from the 4/4 time signature to the 3/4 time signature, the song position switch is moved to the position Tp.
When operated with 1, the position Tj starts from the first beat and a half of the next measure, which is the fourth and a half beats from the first beat of the measure of 3/4 time.
You can jump to and play automatically. The same applies when the song position switch is operated at the position Tp2. Furthermore, even when the song position switch is operated at the position Tp3, 1 of the measure of 3/4 beat
From the first beat and a half of the next measure (the measure next to Tp1) which is the fourth and a half beats counting from the beat, the performance is automatically jumped to the position Tj.

Next, in FIG. 9, the position Tj of the song position marker assigned to the operated song position switch is set to the second beat of the 3/4 time signature, and the bar of the 4/4 time signature is set during the automatic performance. The position when the song position switch is operated at the first and a half beats of is indicated by Tp1, and the position when the song position switch is operated at the second and a half beats of the 3/4 time bar is indicated by Tp2. The position when the song position switch is operated at the third and a half beats of the 3 / 4-beat measure is indicated by Tp3. In this case, the position Tj is the second beat, and the time signature is 3 /
Since it has been changed from 4 beats to 4/4 beats, when the song position switch is operated at the position Tp1, the song is automatically played by jumping from the second beat of the measure of 4/4 beats to the position Tj. Like Also, the position Tp2
When the song position switch is operated, since the second beat is in the past, the song is automatically played by jumping to the position Tj from the second beat of the next 4/4 time bar. In addition, set the song position switch to position Tp.
When the operation is performed at 3, the jump is made to the position Tj from the second beat of the 3 / 4-beat measure next to that measure, and the performance is automatically performed.

By the way, the loop end marker can be embedded in the song data by the event data of the loop end marker described in the text meta event and the timing data indicating the time position thereof, like the song position marker. The loop end marker can be inserted at an arbitrary position, and one or more loop end markers can be inserted for one song position marker section. In the example shown in FIG. 3, three loop end markers SPJ-LE3, SPJ-LE21, SPJ-LE22.
Has been inserted. Loop end marker SPJ-LE
3 is inserted between the third song position marker SPJ-03 and the second song position marker SPJ-02, and the loop end marker SPJ-LE2.

It is inserted between PJ-04. These loop end markers are loop end positions for loop reproduction when the loop switch 35 shown in FIG. 3 is operated to turn on loop reproduction.

Explaining it concretely in the example shown in FIG. 3, when the loop switch 35 is pressed, it will play to some marker position that appears next, return to the song position marker immediately before, and move to any marker that appears next. The specified number of times specified in the song position marker,
Or play infinitely. That is, when the loop switch 35 is operated between the first song position marker SPJ-01 and the third song position marker SPJ-03, the first song position marker SPJ-01.
And the third song position marker SPJ-03 are repeated five times as specified by the first song position marker SPJ-01 for automatic performance. After that, it will proceed to the next. Also, the third song position marker S
When the loop switch 35 is operated between the PJ-03 and the loop end marker LE3, the third song position marker SPJ-03 is designated between the third song position marker SPJ-03 and the loop end marker LE3. Infinite number of times (until the loop switch 35 is operated again to cancel the loop reproduction), the automatic performance is repeated.

When the loop switch 35 is pressed between the loop end marker LE3 and the second song position marker SPJ-02, the second song position marker SPJ-02 is played first, and then the third song position marker SPJ-02 is played. Returning to the marker SPJ-03, the portion between the loop end marker LE3 and the loop end marker LE3 is repeated infinitely repeatedly as specified by the third song position marker SPJ-03, and is automatically played. Furthermore, the second song position marker SPJ-02 and the loop end marker LE21.
When the loop switch 35 is pressed between the second song position marker SPJ-02 and the loop end marker LE21, the second song position marker SP21
Automatically repeats an infinite number of times specified by J-02. Furthermore, when the loop button is pressed between the loop end marker LE21 and the loop end marker LE22, first the loop end marker LE22 is played, and then the second song position marker SPJ-0.
Return to No. 2 and make a second line between the loop end marker LE21.
The song position marker SPJ-02 will be played repeatedly indefinitely.

Furthermore, the loop end marker LE2
When the loop button is pressed between the second and fourth song position marker SPJ-04, first the fourth song position marker SPJ-04 is played, and then the second song position marker SPJ-02 is returned to, the loop end The marker LE21 is automatically played repeatedly infinitely as specified by the second song position marker SPJ-02. Furthermore, if the loop button is pressed after being designated by the fourth song position marker SPJ-04, the song will be played until the end of the song, and then the song designated by the fourth song position marker SPJ-04 will be performed. During the end, the automatic performance is repeated twice as specified by the fourth song position marker SPJ-04. Then, after that, the automatic performance ends.

By the way, as shown in FIG. 3, light emitting elements LED1 to LED5 are provided on the song position switches 31 to 34 and the loop switch 35, respectively. The light emitting elements LED1 to LED4 can emit light in green and red, for example, and the light emitting element LED5 can emit light in green, for example. The light emitting elements LED1 to LED4 provided corresponding to the song position switches 31 to 34 emit green light when a corresponding song position marker is set in the loaded song data. This is when the area of the song position marker is not being automatically played, and when the area of the song position marker is being automatically played, red light is emitted. Further, the light emitting element LED5 in the loop switch 35 emits green light when the loop reproduction is turned on. Since the song position switches 31 to 34 and the loop switch 35 are toggle switches whose states are inverted each time they are operated, it is possible to easily cancel the jump instruction to the song position and the loop reproduction instruction. Become.

When any button or the like for editing the song data is operated, the song data editing process is started, and it is determined in step S21 whether or not the position of the song position marker is to be edited. If it is determined that the editing of the position correction of the song position marker is instructed, the process proceeds to step S22 and the position of the song position marker is corrected according to the operation of the panel operator 22. In this case, at least one of the measure, beat, and clock is modified, and the modification may be designated by a numerical value, or the position of the marker displayed on the display 24 may be moved. However, when the distance between the two song position markers is within a predetermined value, the correction is invalidated or automatically set to exceed the predetermined value. For example, 2
When the distance between two markers is within 1 beat, the correction is invalidated or set to 1 beat. Then, similarly to the case where it is determined in step S21 that the edit of the position correction of the song position marker is not instructed, the process proceeds to step S23.

In step S23, it is determined whether the name of the song position marker or the number of loops has been edited. Here, if it is determined that the name of the song position marker or the editing of the number of loops is instructed, the process proceeds to step S24 and the name of the song position marker and the number of loops are corrected according to the operation of the panel operator 22. Then, as in the case where it is determined in step S23 that the edit of the position correction of the song position marker is not instructed, the process proceeds to step S25. In step S25, it is determined whether or not another event has been edited. If it is determined that the editing of the event such as the note data, the control change data, the program change data, or the like is instructed, the process proceeds to step S26, and the event data instructed according to the operation of the panel operator 22 is changed. Fix it. Then, the process proceeds to step S27 as in the case where it is determined in step S25 that the editing of the other event is not instructed.

In step S27, it is determined whether or not the end of editing is instructed. If it is determined that the end of editing is instructed, in step S28 the song position marker in the song data after editing is checked. To be done. Then, the setting information corresponding to the checked song position marker is acquired,
In step S29, the song position information storage area secured in the RAM 13 is stored as shown in FIG. The setting information can be acquired by reading the setting data such as control change or program change from the beginning of the song data while updating it to the position of the song position marker, or from the position of the song position marker to the beginning of the song data. This is performed by searching the setting data and acquiring the found setting data. When the processing of step S29 ends, the music data editing processing ends. If it is determined in step S27 that the editing is continued, the process returns to step S21 and the processes of steps S21 to S26 are repeatedly executed to edit the music data.

In the song data editing process,
You may make it display the song position marker information which reflected the edit result on the display 24. Also,
As will be described later, the song position marker is inserted into the song data by operating (double-clicking) the song position switches 31 to 34 at the time of playing the song data. It may be inserted.
Also, the inserted song position marker may be deleted. Furthermore, the insertion, editing, and deletion of loop end markers can be performed by an external MIDI sequencer (a MIDI sequencer that can handle text meta events).
Although any sequencer may be used), the loop end marker may be inserted or edited in the song data editing process.

Next, FIG. 1 is a flowchart of a music piece data reproducing process executed in the automatic performance device according to the present invention.
3 to FIG. When the start of the automatic performance is instructed, the music data reproduction process is started and it is determined whether or not the event reproduction timing read in step S31 has been reached. Whether or not the event reproduction timing has been reached is determined by comparing the value of the timer separately counted according to the tempo with the value of the timing data of the event data. Here, when it is determined that the time indicated by the timing data has been reached, the process proceeds to step S32, and it is determined whether or not the event is a song position marker. If it is determined that the event is a song position marker, it is determined in step S33 whether the loop reproduction mode is set. Here, when the loop switch 35 is operated and it is determined that the loop playback mode is set, it is determined in step S34 whether or not the song position marker that has reached the event playback timing is other than the first song position marker of the song data. It This process is performed so that the song position marker at the beginning of the song data will not be looped because there is no loop destination.

Here, if it is determined that the song position marker that has reached the event reproduction timing is other than the song position marker at the beginning of the song data, loop reproduction is possible, and therefore, the previous song position marker is reached in step S35. Jump and reflect the setting information at the jumped song position marker. Next, in step S36, it is determined whether the number of loops set in the jumped song position marker is a finite number. Here, when the number of loops is a finite number of times like the first song position marker and the fourth song position marker, in the song position marker stored in the song position information storage area in step S37. The loop count is decremented by "1". Further, as a result of the decrement, it is determined whether or not the number of loops has become “0”. Here, if it is determined that the number of loops has become “0”, the loop mode is canceled in step S39, and the corresponding light emitting element LED5 is turned off.
When the process of step S39 ends, the process proceeds to step S46 shown in FIG.

If it is determined in step S31 that the time indicated by the timing data has not been reached, the processes of steps S32 to S39 are skipped and the process proceeds to step S46 shown in FIG. Also, step S3
If it is determined in 6 that the number of loops is not a finite number, the processes of steps S37 to S39 are skipped and the process proceeds to step S46 shown in FIG. Further, when it is determined in step S38 that the number of loops is not "0", the process of step S39 is skipped and the process proceeds to step S46 shown in FIG. Also,
If it is determined in step S33 that the mode is not the loop playback mode, and if it is determined in step S34 that the song position marker is the head song position marker, the jump is made to the position of the song position marker detected in step S32. If there is a light emitting element LED corresponding to the song position marker before the jump which is lit in red which is the second aspect, the process is branched to step S40, and the light emitting element LED is made to emit the green color which is the first aspect. . Next, in step S41, the light emitting element LED corresponding to the jump destination song position marker detected in step S32 is caused to emit light in red which is the second mode. When the process of step S41 ends, the process proceeds to step S46 shown in FIG.

If it is determined in step S32 that the event reaching the event reproduction timing is not the song position marker, the process branches to step S42 to determine whether the event is the loop end marker. If it is determined that the event is the loop end marker, it is determined in step S43 whether the loop reproduction mode is set. Here, if the loop switch 35 is operated and it is determined that the loop reproduction mode is set, it is determined in step S44 whether or not there is a song position marker before the loop end marker that has reached the event reproduction timing. Here, if there is a song position marker before the loop end marker, the process jumps to step S35 described above. And
When the processes of steps S35 to S39 described above are executed and the process of step S39 ends, the process shown in FIG.
Go to step S46 shown in. If it is determined in step S42 that the event reaching the event reproduction timing is not the loop end marker, the process branches to step S45 to perform other event processing. Examples of other event processing include sound generation processing and mute processing for note events, tone color setting processing for program change events, various setting processing such as volume and effects for control change events, pitch change processing for pitch bend events, and time signature for beat events. The change process and the tempo change process for the tempo change event are completed. If it is determined in step S43 that the loop reproduction mode is not set, and if there is no song position marker before the loop end marker that has reached the event reproduction timing in step S44 and there is no return song position marker. If determined, the process proceeds to step S46 shown in FIG.

In step S46 shown in FIG. 14, it is determined whether or not the song position switch is single-clicked. When the song position switch is single-clicked, the process of jumping to the position of the song position marker corresponding to the operated song position switch is performed. Therefore, when the single-click is performed and YES is determined in step S46, In step S47, it is determined whether the non-jump waiting mode is set. The jump wait mode is a mode from the operation of the song position switch to the actual jump, and the jump wait mode is from the position Tp shown in FIGS. 5 to 9 described above until the jump timing. If it is determined that the non-jump mode is set, the timing of the playing position of the song position marker corresponding to the song position switch operated in step S48 is checked, and the jump timing is set. When to jump
This is as described above with reference to FIGS. Then, in step S49, the jump waiting mode is set, and the light emitting element LED corresponding to the song position switch operated in step S50 is turned on in the third mode, for example, blinking green light.

If it is determined in step S47 that the jump waiting mode is set, step S5
Branch to 4. When the song position switch is operated further in the jump wait mode, jumping is cleared when the same song position switch is operated, and when a different song position switch is operated. It is reset so that it jumps to the position of the song position marker that corresponds to the song position switch. Such processing is executed in the processing of step S54 and thereafter, and step S54
Then, the jump waiting mode is cleared, and further the jump timing set in step S55 is cleared. Next, the light emitting element LED corresponding to the cleared jump position is made to emit the green light which is the first mode. Next, in step S57, it is determined whether the same song position switch as the song position switch that was operated when the jump waiting mode was set was operated. If it is determined that the same song position switch has been operated, the corresponding jump set has been cleared in steps S54 to S56, and the process directly proceeds to step S51.
If it is determined that a different song position switch has been operated, the process branches to step S48 and step S4.
The jump to the position of the song position marker corresponding to the newly operated song position switch is set by performing the above-described processing in step S50 from step 8. The jump set so far has been cleared in steps S54 to S56.

When the processing in step S50 is completed, it is determined in step S51 whether or not the song position switch has been double-clicked. When the song position switch is double-clicked, the beginning position of the bar at the current playing position becomes the song position marker for that song position switch. Therefore, in step S52, the start timing of the current measure is stored in the bar number, beat number, and clock fields of the song position information storage area corresponding to the double-clicked song position switch. Next, the setting data column of the corresponding song position information storage area stores setting data such as a program change or control change at the beginning of the current bar. As a result, if the song position marker information is already stored in the corresponding song position information storage area, the corresponding song position marker is updated, and if it is not stored, a new song position marker is added. Become. When the process of step S53 ends, the process proceeds to step S58 shown in FIG. During automatic performance, setting data such as program change and control change at the current bar head position is buffered each time the bar head is reached.

In step S58, it is determined whether or not the jump timing set in step S48 has been reached. If it is determined that the jump timing has been reached, the jump position is jumped to the position of the song position marker and the setting data such as program change and control change at the song position marker is reflected. Then, step S
At 60, the light emitting element LED in the song position switch corresponding to the song position marker of the jump destination
Is lighted in red which is the second mode, and the other light emitting elements LEDs are lighted in green which is the first mode. Then, as in the case where it is determined in step S58 that the jump timing has not been reached, the process proceeds to step S61.

In step S61, the loop switch 35
It is determined whether or not has been operated. If it is determined that the loop switch 35 has been operated, step S62.
Determines whether or not it is currently in loop mode,
If it is determined that the loop mode is currently set, the loop mode is canceled in step S63. That is, the loop reproduction can be canceled by operating the loop switch 35 during the loop reproduction. If it is determined in step S62 that the loop mode is not currently set, the process branches to step S64 and the loop reproduction mode is set. When it is determined in step S61 that the loop switch 35 is not operated, and in step S63 or step S64.
When the processing of step S6 is completed, the process proceeds to step S65, and it is determined whether or not the reading of all the event data is completed and the music piece data is completed. If it is determined that the song data has ended, the song data reproduction process ends. Also,
If the music data has not ended, the process returns to step S31 and the above-mentioned music data reproduction processing is repeatedly executed.

Next, FIG. 1 is a flow chart of a music data storage process executed in the automatic performance device 1 according to the present invention.
6 shows. When a button or the like instructing the storage of the music data loaded in the RAM 13 is operated, the music data storage processing shown in FIG. 16 is started, and the RAM 1 is stored in step S71.
The timing data and event data of the song position marker in the song data loaded in No. 3 are deleted. Then, in step S72, the timing position information and event data of the song position marker are created by referring to the contents of the song position information storage area and R
It is inserted in the music data loaded in AM13. Next, in step S73, the song data stored in the RAM 13 in which the newly created song position marker is inserted is saved in a storage medium such as the external storage device 14. As a result, even when the song position marker of the song data loaded in the RAM 13 is edited, the edited song data is saved in the storage medium.

By the way, the present invention may have a form in which an automatic performance application software called an automatic performance program is installed in a personal computer, such as a karaoke device,
It may be applied to a game device, a portable communication terminal such as a mobile phone, and an automatic playing piano. When applied to a mobile communication terminal, not only the case where the predetermined function is completed only by the terminal, but a part of the function is given to the server side, and the predetermined function is realized as the entire system including the terminal and the server. You may do it. Further, the form of the automatic performance device according to the present invention can be an electronic musical instrument. In this case, the electronic musical instrument is not limited to a keyboard musical instrument, but may be a string musical instrument type, a wind instrument type, a percussion musical instrument type, or the like. In addition, the automatic performance device according to the present invention is a device separate from the electronic musical instrument body,
Each device may be connected using communication means such as I or various networks. Further, the automatic performance program and song data according to the present invention may be supplied to an electronic musical instrument or a personal computer from an external storage medium or an external device via the communication interface 19. The communication interface 19 and the communication network 18 are not limited to wired ones and may be wireless. Also, both may be provided.

Furthermore, the data structure of the music data according to the present invention is "event + relative time" in which the occurrence time of a performance event is represented by the time from the previous event, and the occurrence time of a performance event is music or measure. "Event + Absolute time" expressed in absolute time, "Pitch (rest) + note length" that represents performance data in terms of note pitch and note length or rest and rest length, minimum resolution of performance Any form may be used, such as a "solid method" in which a memory area is secured for each time and the performance event is stored in the memory area corresponding to the time when the performance event occurs. Furthermore, the processing method for automatically playing music data is to change the processing cycle according to the set tempo, the processing cycle is constant, and the value of the timing data in the music data is changed according to the set tempo.

Furthermore, the method of storing the music data for a plurality of channels may be a format in which the data of a plurality of channels are mixedly stored, or a format in which the data of each channel is stored separately for each track. Furthermore, in the memory, the time-series music data may be stored in a continuous area, or the data scattered and stored in the scattered areas may be separately managed as continuous data. It is good (that is, it is sufficient that the data can be managed as continuous data in time series, and it does not matter whether or not the data is continuously stored in the memory).

[0051]

Since the present invention is configured as described above, it is possible to insert a song position marker or a loop end marker indicating a specific performance position in the music data into the music data. Therefore, when the song data is changed, the song position marker and the loop end marker are detected from the song data and automatically set. Therefore, even if the music data is changed, it is possible to easily perform a jump to an arbitrary position in the music data and a loop reproduction of an arbitrary section. Since a song position marker and a loop end marker can be inserted in the song data as event data, song position setting and loop end setting can be easily performed for each song data. The timing of the song position marker and the loop end marker can be set in non-measure units, for example, the number of measures, the number of beats, and the clock. In this case, if the markers are too close to each other, it is meaningless to set them, and therefore it is preferable that the markers cannot be set. When jumping to the specified song position marker, when the performance position reaches the in-measure position corresponding to the position of the specified song position marker, which is reached after the jump is specified, the specified song I try to jump to the performance position of the position marker. As a result, the user can jump without making the user feel uncomfortable.

Furthermore, since the loop end can be set by the loop end marker in addition to the song position in loop reproduction, the loop end can be set at any position other than the song position. Further, since the display means such as the LED is provided corresponding to the song position marker, it is possible to grasp which song position is currently being reproduced by the display means. Furthermore, since the name and the number of loops can be set for each song position marker, the song position can be easily understood and the loop playback can be freely controlled. If the switch means for instructing to jump to the song position is a toggle switch whose state is inverted each time it is operated, the instruction to jump to the song position can be easily canceled.
