[0002]
[Prior art]
Conventionally, some electronic musical instruments have an automatic performance function. For example, in order to perform accompaniment according to various styles (genre etc.) of music such as rock and country, pattern information is stored in advance according to the style type. ing. Then, in accordance with the performance of the performer, the pattern information corresponding to the selected style type is reproduced and the automatic performance is performed.
[0003]
The pattern information includes the main section that is used mainly for the performance of the entire song, the intro section that is used to play the prelude of the song, the fill-in section that is used to connect phrases in the middle of the song, and the end of the song. There are multiple section types, such as an ending section, used for playing parts. Each section type has a plurality of variations (for example, main A, main B, etc. for the main section).
[0004]
When the pattern information is switched during performance, the performer operates the style selection switch to switch the style type, or operates the section selection switch to switch the section type. In this specification, the performance pattern itself generated by reproducing the pattern information is simply referred to as “pattern”.
[0005]
[Problems to be solved by the invention]
Conventionally, pattern information can be switched as desired using a style selection switch or section selection switch, but when switching to pattern information to be reproduced next during a performance, a switch corresponding to the style type or section type after switching In addition, there is a case where a plurality of switches such as a style selection switch or a section selection switch must be operated at the same time.

7 to 11 are flowcharts of a control program (automatic performance program) executed by the CPU 1, FIG. 7 is a flowchart showing an example of the main process, and FIG. 8 is an example of the foot switch interrupt process (type 1). 9 is a flowchart showing an example of the operation of the foot switch interrupt process (type 2), FIG. 10 is a flowchart showing an example of the operation of the pattern interrupt process, and FIG. 11 is a flowchart showing an example of the operation of the song interrupt process. is there. Hereinafter, the control operation of the CPU 1 will be described based on each flowchart.
[0031]
When the main processing of FIG. 7 is started by turning on the power or the like, it is determined in step S1 whether or not a style type is selected by a style selection switch. If a style type is not selected, the process proceeds to step S3, where the style type is selected. Then, in step S2, reading of pattern information corresponding to the selected style type and the currently selected (selected) section type is set, and the process proceeds to step S3. Note that in the initial state when the power is turned on, the style type and section type are set to factory defaults, or the style type and section type selected at the previous power-off time are set.
[0032]
In step S3, it is determined whether or not the section type is selected by the section selection switch. If the section type is not selected, the process proceeds to step S5. If the section type is selected, the selected section type and the current section type are selected in step S4. The reading of the pattern information corresponding to the selected (selected) style type is set, and the process proceeds to step S5.
[0033]
In step S5, it is determined whether or not the pattern information reproduction start is instructed by the pattern reproduction switch. If the pattern information reproduction start is not instructed, the process proceeds to step S7. If the pattern information reproduction start is instructed, step S6 is performed. Thus, the foot switch interrupt process and the pattern interrupt process are activated (interrupt permitted), and the process proceeds to step S7. By starting this interrupt process, the foot switch interrupt process of FIG. 8 (type 1) and the pattern interrupt process of FIG. 10 can be executed.
[0034]
In step S7, it is determined whether or not the song information reproduction start is instructed by the song reproduction switch. If the song information reproduction start is not instructed, the process proceeds to step S10. If the song information reproduction start is instructed, step S8 is performed. In step S9, read pattern information corresponding to the first instruction event of the song information (pattern sequence) is set, and in step S9, pattern interrupt processing, song interrupt processing and foot switch interrupt processing are started (interrupt). Permission) and proceed to step S10. By starting this interrupt process, the foot switch interrupt process of FIG. 9 (type 2), the pattern interrupt process of FIG. 10, and the song interrupt process of FIG. 11 can be executed.
[0035]
In step S10, a pattern switching information creation / editing process is executed, and the process proceeds to step S11. In this creation / editing process, when a predetermined operation corresponding to creation is detected, a step of performing the creation process corresponding to the operation (pattern switching information creating means), and when a predetermined operation corresponding to editing is detected, There is a step (pattern switching information editing means) for performing an editing process corresponding to the operation. Each process is executed in accordance with the operation, and processes such as selection of pattern switching information, input of data, and storage of pattern switching information are performed. . If a predetermined operation corresponding to creation or editing is not detected, the process immediately proceeds to step S11.
[0036]
In step S11, song information is created, edited and added, pattern information is created, edited and added, pattern playback and song playback are stopped (the interrupt processing being started is stopped), various settings are changed, and the like. In step S12, it is determined whether or not there is an end instruction. If there is an end instruction, the process ends. If there is no end instruction, the process returns to step S1. Note that each processing in step S11 is also executed when a corresponding predetermined operation is detected, and if a predetermined operation is not detected, the process immediately proceeds to step S12. As a result, this main process repeats until the apparatus main body is started and then stopped.
[0037]
The foot switch interrupt process (type 1) in FIG. 8 is executed whenever the foot switch is operated during pattern reproduction. In step S21, referring to the pattern switching information, reading of the next pattern information is set and the process returns to the original routine. That is, the switching event data stored in the pattern switching information is sequentially read one by one for each foot switch operation, and the section type designated by the read switching event data and selected (and reproduced) at that time The reading of pattern information corresponding to the style type being set is set (reproduction initial setting), and the pattern information to be reproduced is switched.
[0038]
The foot switch interrupt process (type 2) in FIG. 9 is executed each time the foot switch is operated during song playback. First, in step S31, data (switching event data) corresponding to the currently reproduced pattern information is detected from the pattern switching information, and in step S32, new pattern information is generated in accordance with the data stored next to the detected data. Set to read and return to the original routine. In other words, this process is executed by a two-stage process in which the section type of the pattern information being reproduced is detected, and the section type specified to be reproduced next to the detected section type is read from the pattern switching information. Is done.
[0039]
Specifically, in step S31, the section type of the pattern information being reproduced when the foot switch is operated is detected, and switching event data indicating the same section type as the detected section type is included in the pattern switching information. Detect from. Next, in step S32, the switching event data next to the switching event data detected in step S31 is read, and the section type specified by the switching event data and the style type selected (reproduced) at that time Is set (reproduction initial setting), and the pattern information to be reproduced is switched.
[0040]
The pattern interruption process in FIG. 10 is started at predetermined times (clock timing) during pattern reproduction and song reproduction. First, in step S41, a process for detecting musical tone event data to be processed at the current timing is performed from the pattern information for which reading is set, and the presence or absence of musical tone event data to be processed is determined in step S42. If there is no musical sound event data to be processed, the process proceeds to step S44. If there is musical sound event data to be processed, the musical sound event data detected in step S43 is read out, and predetermined processing such as sound generation / mute is performed, and then step S44 is performed. Proceed to
[0041]
In step S44, it is determined whether or not the pattern information has been read to the end. If the pattern information has not been read to the end, the process returns to the original routine. Set so that re-reading starts from the beginning, and return to the original routine. As a result, various information can be read from the pattern information selected in sequence by operating the foot switch, specifying pattern switching information switching event data, section selection switch operation, style selection switch operation, etc., and reproducing the pattern information. Is done.
[0042]
The song interruption process in FIG. 11 is started at every predetermined time (clock timing) during song reproduction. First, in step S51, processing for detecting instruction event data to be processed at the current timing is performed from the song information (pattern sequence) set to be read, and the presence or absence of instruction event data to be processed is determined in step S52. . If there is no instruction event data to be processed, the process proceeds to step S54. If there is instruction event data to be processed, reading of pattern information instructed based on the instruction event data detected in step S53 is set, and the process proceeds to step S54. move on.
[0043]
In step S54, it is determined whether or not the song information has been read to the end. If it has not been read to the end, the process returns to the original routine. If it has been read to the end, the start of various interrupt processing is stopped in step S55. (Interrupt disabled), end song playback and return to the original routine. As a result, various information (instruction event data) is sequentially read out from the song information, and an instruction to switch patterns according to the song information (pattern sequence) is issued.
[0044]
By the above processes, for example, the following operation is performed. FIG. 1 is a diagram conceptually showing an example of pattern reproduction operation. The pattern A is a pattern obtained by reproducing the pattern information selected at the start of pattern reproduction (pattern information corresponding to the selected style type and section type). The pattern B is a pattern obtained by reproducing the pattern information defined to be read next to the pattern A in the pattern switching information. In the embodiment, the pattern switching information defines only the section type, the style type of the pattern B follows the style type of the pattern (pattern A) before switching, and the section type is defined by the pattern switching information.
[0045]
The pattern C is a pattern obtained by reproducing pattern information defined by the style type selected by the style selection switch and the section type of the pattern (pattern B) that has been reproduced so far. In this example, the section type is followed by the selection of the style type, but when the section type is selected, the style type of the pattern that has been reproduced is followed. The pattern D is a pattern obtained by reproducing the pattern information defined to be read next to the pattern C in the pattern switching information. As described above, the pattern switching information defines only the section type. In this case as well, as with pattern B, the style type of pattern D follows the style type of the pattern (pattern C) before switching, and the section type is It is defined by the pattern switching information.
[0046]
FIG. 2 is a diagram conceptually showing an operation example of song reproduction. The pattern A is a pattern in which pattern information read at the start of song reproduction, that is, pattern information indicated by instruction data stored at the head of song information (pattern sequence) is reproduced. The pattern B is a pattern obtained by reproducing the pattern information indicated by the second instruction data of the song information (pattern sequence). This pattern may follow the style type or section type of the previous pattern depending on the content indicated by the instruction data. The pattern C is a pattern obtained by reproducing the pattern information defined to be read next to the pattern B in the pattern switching information. In the embodiment, the pattern switching information defines only the section type, the style type of the pattern C is the same as the pattern (pattern B) before switching, and the section type is the section type of the pattern B in the pattern switching information. It is defined by the switching event data next to the matching switching event data.
[0047]
The pattern D is a pattern obtained by reproducing the pattern information defined to be read next to the pattern C in the pattern switching information. As described above, the pattern switching information defines only the section type. Similar to the pattern C, the style type of the pattern D is the same as that of the pattern C before switching, and the section type is defined by the pattern switching information. The pattern E is a pattern obtained by reproducing the pattern information indicated by the third instruction data of the song information (pattern sequence). In this case as well, the style type of the previous pattern is determined according to the content indicated by the instruction data. And may follow the section type. That is, in this example, in the song information (pattern sequence), the pattern information is defined in the order of pattern A → pattern B → pattern E, and the footsteps before switching from pattern B to pattern E are performed. In this example, the switch is operated twice and the pattern information is switched based on the pattern switching information.
[0048]
Note that when the pattern is changed by operating the style selection switch, section selection switch, or foot switch, the pattern switching timing is not limited to the method of changing the pattern when each switch is operated. The pattern may be changed when a predetermined timing such as head timing or beat timing arrives.
[0049]
In the embodiment, the switching event data of the pattern switching information represents the switching order of the section type, and can follow the style type. This is most useful, but besides this, the switching order of the style type is stored. Save the switching order of the style type and section type pair, and prepare the style type switching order information and the section type switching order information as separate files (pattern switching information), You may make it utilize them selectively or simultaneously. When using simultaneously, it is good to set so that each information may be switched by different operators.
[0050]
The switching operation means for instructing pattern switching based on the pattern switching information may be an operator other than the foot switch. However, since the pattern is switched during pattern reproduction, an operator that can easily perform the switching operation is preferable. For example, a foot switch that can be operated with a foot is preferable. In addition to the operation element, the switching operation means may recognize a predetermined voice input and perform pattern switching.
[0051]
Alternatively, pattern switching information may be prepared for each style type, for each section type, for each song information, and used according to the style type, section type, or song information.
[0052]
In the foot switch interrupt process, type 1 may be used during song playback, and type 2 may be used during pattern playback.
[0053]
Moreover, although embodiment demonstrated the case where the control program was previously memorize | stored in ROM2, it may be as follows not only in this. The HDD of the external storage device 9 is a storage device for storing control programs and various data (pattern information, song information, pattern switching information, etc.). When the control program is not stored in the ROM 2, the control program is stored in the HDD, and when the control program is read into the RAM 3, the CPU 1 can be operated in the same manner as when the control program is stored in the ROM 2. it can. In this way, control programs can be easily added and upgraded. The CD-ROM drive of the external storage device 9 is a device that reads a control program and various data stored in the CD-ROM. Therefore, a control program and various data are recorded on the CD-ROM, and the control program is loaded onto the HDD from the CD-ROM drive. As a result, a new installation or version upgrade of the control program can be easily performed. In addition to the CD-ROM drive, as the external storage device 9, a device for using various types of media such as a floppy disk device and a magneto-optical disk (MO) device may be provided.
[0054]
