Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic accompaniment apparatus and a program suitable for synchronizing the performance of automatic accompaniment style data from a specific section.
[0002]
[Prior art]
The automatic accompaniment device has a function called “sync start” that starts automatic accompaniment (playback of accompaniment style data expressed in chords) in synchronization with a performance operation of pressing a keyboard or the like. In accompaniment when performing performance or the like, it is useful to synchronize the performance of automatic accompaniment style data from a specific section, for example, an intro section.
[0003]
When sync start is started from the intro section of the automatic accompaniment style data, the conventional sync start setting method is to stop the automatic accompaniment during performance by operating the automatic accompaniment stop switch provided on the panel, and operate the intro switch. Then, by selecting the intro section of the automatic accompaniment to be played next, and further operating the synchro switch, it is possible to set the standby state for the synchro start from the intro section of the automatic accompaniment. For this reason, many times of switch operations are required to set the standby for the synchro start from the intro section.
[0004]
In another setting method, the standby state of the synchro start from the intro section can be set by turning on the synchro switch during the reproduction of the intro section automatically accompanied. In this case, if the operation timing is removed and the synchro switch is turned on during playback of the main section, the standby state for sync start from the main section of the automatic performance is set.
[0005]
As described above, in the conventional apparatus, the operation for setting the standby state of the synchro start from the intro section takes time, or the operation does not take time, but the sync switch is turned on while the intro section is being played back. There was an inconvenience that turning on was not an easy task.
[0006]

It can also be stored in the storage device 5.
[0022]
A performance information processing device 16 such as another electronic musical instrument is connected to the MIDII / F 10 so that performance information can be exchanged in the MIDI format. In addition, although FIG. 1 demonstrated the system using an electronic musical instrument, you may comprise an automatic accompaniment system using a personal computer (PC) terminal.
[0023]
[Configuration example of automatic accompaniment information]
FIG. 2 is a diagram showing a configuration example of automatic accompaniment information used in the automatic accompaniment system according to one embodiment of the present invention. Automatic accompaniment information (automatic accompaniment data) is called “accompaniment style data” or simply “style data”, and a plurality of accompaniment style data is stored in the ROM 3 in advance. The accompaniment style data is performance data for reproducing accompaniment parts such as chord parts, bass parts, and drum parts, and is prepared for each genre or musical style. The user can also create new style data and store it in the RAM 4 or the external storage device 5.
[0024]
One (accompaniment) style includes multiple sections of performance data (chords, bass, and rhythm), and the types of sections include the intro section (the beginning of the song), the main section (the middle section), There is an ending section (tail). As shown on the left side of FIG. 2, one style data starts with a style number indicating the number of the style data, and an intro section (“Intro”), a main section (“Main”), an ending section (“Ending”). ) Followed by performance data, ending with “end” data.
[0025]
The performance data (section data) of each section is performance data for automatically playing the accompaniment music of several measures length (1 to 2 measures) corresponding to the section. As shown on the right side of FIG. Following the setting information such as the tempo, tone color, and volume for setting the playback mode at the time of performance, a set of performance events and processing timings constituting the performance data of the section follows, and ends with “end” data. Note that the section data is created to represent music along a specific chord (generally C major), and during automatic accompaniment, the pitch of the performance event read from the section data is specified by pressing a key. The pitch is converted based on the chords to be generated.
[0026]
[Example of operation]
FIG. 3 shows an example of the operation when the intro / sync start standby state is set in the automatic accompaniment system according to the embodiment of the present invention. A very schematic operation example of the synchro start setting in this automatic accompaniment system will be described with reference to FIG. 3. In this system, a “style selection” switch is used to designate a synchro start standby. In addition, accompaniment style data (automatic accompaniment information) represented by “style A”, “style B”, “style C”,... Can be selected by designating a style number using a numeric keypad. Consists of performance data of a plurality of sections represented by “main” or the like. When the “style selection” switch is operated during the reproduction of the accompaniment style data “style A” (T1), the reproduction of “style A” is immediately stopped, and the specific section data “intro” is set to the synchronization start standby state. . Therefore, when the key is pressed as it is (T2), the reproduction of “Intro” of “Style A” is started. On the other hand, when “Style B” is selected by the numeric keypad operation between the switch operation (T1) and the key press (T2) (T12), the specific section data “Intro” of “Style B” is synchronized at that timing (T12). Set to start standby.
[0027]
The operation will be described more specifically. Now, for example, as shown on the left side of FIG. 3, when playing performance data (section data) of an arbitrary section (eg, main section as shown) of “accompaniment style data A”, When the “style selection” switch of the panel operator of the operator device 12 is operated at the timing T1, the system waits for an intro section sync start (intro sync start) of “accompaniment style data A”. Set to
[0028]
Next, when there is a key depression (designating a chord) at timing T2, reproduction of performance data (intro section data) of the intro section of “accompaniment style data A” is started. When the reproduction of the intro section data of “accompaniment style data A” is completed at time (timing) T3, the reproduction of the main section data of “accompaniment style data A” is started.
[0029]
Further, during the reproduction of an arbitrary section data of an arbitrary accompaniment style data (for example, main section data of “accompaniment style data A” as shown in the figure), after the “style selection” switch is operated at timing T1, Without a key, at timing T12, if there is further operation of the numeric keypad for selecting the style of “accompaniment style data B”, intro synchronization start of “accompaniment style data B” is waited at timing T12. The setting is switched as follows.
[0030]
In this case, as shown in parentheses in FIG. 3, the reproduction of the intro section data of “accompaniment style data B” is started when there is a key depression (designating a chord) at timing T2. Then, when the reproduction of the intro section data of “accompaniment style data B” is completed at time T3, the reproduction of the main section data of “accompaniment style data B” is started.
[0031]
[Operation example of main processing]
FIG. 4 is a flowchart showing an operation example of the main processing according to one embodiment of the present invention. This main processing includes automatic accompaniment processing having a synchro start standby setting function and sound generation processing based on keyboard operation. The flowchart of FIG. 4 is turned off when the automatic accompaniment system (electronic musical instrument) is turned on. Represents the operation of the main process that has been activated until. When the main process is started by turning on the power, it is determined in step S1 whether or not the operation of the “start / stop” switch is detected.
[0032]
Here, when the operation of the “start / stop” switch is detected (S1 → YES), the process proceeds to step S2, and the processing of steps S2 to S4 starts and stops the automatic accompaniment for each operation of the “start / stop” switch. Set by switching. That is, in step S2, it is determined whether or not the automatic accompaniment is being reproduced. If automatic accompaniment is being reproduced (YES), it is instructed to stop the automatic accompaniment reproduction. A reading position (reading pointer) is set at the head position of the ending section data of the accompaniment style. With this setting, playback of the ending section data of the accompaniment style is started in a playback process (FIG. 6) described later, and automatic accompaniment is stopped after the end of the playback of the ending.
[0033]
If it is determined in step S2 that the automatic accompaniment is not being played back (NO), it means that the start of playback has been instructed, so that the process proceeds to step S4 to interrupt a playback process (FIG. 6) described later. Allow and start playback process and start automatic accompaniment. Here, when automatic accompaniment is stopped (when automatic accompaniment is not being played back), the data reading position for playback is always set at the beginning of the intro section data of the selected style at that time. Automatic accompaniment begins with the playback of a selection style intro.
[0034]
When the operation of the “start / stop” switch is not detected in step S1 (NO), or after the processing of steps S3 and S4, the process proceeds to step S5, and whether or not the operation of the “style selection” switch is detected. When the operation of the “style selection” switch is detected, the style selection process (FIG. 5) is performed in step S6, and then the process proceeds to step S7. Otherwise, the process proceeds to step S7.
[0035]
In step S7, the following “other processing” as in (1) to (3) is performed.
(1) Processing based on the numeric keypad operation when the “style selection” switch is not turned on (that is, when not in the synchro standby state):
If the automatic accompaniment is being played, playback of the new accompaniment style starts when a new accompaniment style is selected by operating the numeric keypad. However, the section to be played back is the section that was being played back when the numeric keypad was operated.
If the automatic accompaniment is stopped, the reading position is set at the beginning of the intro section data of the new accompaniment style selected by operating the numeric keypad.
(2) Various processes associated with operations of various switches (panel operation elements) on the panel.
(3) Sound generation processing associated with the operation (press and release key) of the keyboard (performance operator) and chord detection processing from the operated key. And so on.
[0036]
Then, after the process of step S7, it is determined whether or not the end is instructed in step S8. If the end is not instructed (NO), the process returns to step S1, and the operations of steps S1 to S8 are repeated until the end instruction is given. Then, when there is an end instruction (S8 → YES), this main process is ended.
[0037]
FIG. 5 is a flowchart showing an example of the operation of style selection processing according to an embodiment of the present invention. This flowchart shows an operation example of the style selection processing routine executed in step S6 of the main process. When the “style selection” switch is operated by the operation of this flowchart, the following (1) to (3) are performed. Processing operations are performed. That is, (1) or (2) can be performed to set the system to the intro / sync start standby state, and (3) can be performed to start automatic accompaniment from the intro section. :
(1) Set the system to the intro / sync start standby state for the currently selected accompaniment style, and stop the automatic accompaniment when this “style selection” switch is operated during automatic accompaniment playback. Position reset process "(S62), or
(2) “Ten-key operation processing” for setting the accompaniment style newly selected by the ten-key operation performed after the “style selection” switch is operated until the next key is pressed to the intro / sync start standby state. (S64, S65) and
(3) “Keyboard operation detection process” (S67) for starting the automatic accompaniment of (1) or (2) based on the first key depression detection after the “style selection” switch operation.
[0038]
In the first step S61 of the style selection processing routine of FIG. 5, it is determined whether or not the automatic accompaniment is being reproduced when the “style selection” switch is operated, and if it is being reproduced (YES). In step S62 of the “reading position reset process”, style reproduction (automatic accompaniment) is stopped and the reading position is reset. Here, “stop playback of the style” means that the musical sound being played is muted and the playback processing is stopped, and “reset the reading position” means that the intro of the currently selected accompaniment style. This is to move and set the reading position at the beginning of the section data.
[0039]
On the other hand, if the automatic accompaniment is not being played when the “style selection” switch is operated (S61 → NO) and after the process of step S62, the process proceeds to step S63 to determine whether the numeric keypad is operated. When the numeric keypad is operated, the “numeric keypad processing” is performed in steps S64 and S65. This “Numeric keypad operation” is activated when the numeric keypad is operated during the period from when the “Style selection” switch is operated until the next key is pressed (waiting for sync start). A style selection buffer in the RAM 4 is used.
[0040]
That is, in step S64, the style specified by the numeric keypad is changed to the style selection buffer [recording area for storing information (style number) indicating the selected style (the accompaniment style currently selected can be found by referring to the style selection buffer). In step S65, the reading position is set at the beginning of the intro section data of the selected accompaniment style. As described above, when the accompaniment style to be reproduced is changed during standby for the synchro start, the new accompaniment style data after the change is set to be reproduced from the intro section.
[0041]
When the numeric keypad is not operated (S63 → NO) and after the process of step S65, it is determined in step S66 whether or not a key pressing operation is detected. "NO" is determined, and the process returns to the ten-key operation detection step S63. Accordingly, the detection of the numeric keypad operation in step S63 is repeatedly performed until the next key depression operation is performed, and the intro / synchronous start standby state of the accompaniment style in which the reproduction is stopped in step S62 without performing the numeric keypad operation is set. Alternatively, it is possible to change the accompaniment style to be reproduced next by redoing the “numeric key operation process” in steps S64 and S65 by operating the numeric keypad again.
[0042]
Then, after the “style selection” switch is operated, when the key pressing operation is first performed, the determination in step S66 becomes “YES”, the process proceeds to step S67, and the “key pressing operation detecting process” is performed. In this “key press operation detection process”, the interrupt of the playback process (FIG. 6) is permitted when the first key press operation (chord designation by key press) is detected after the “style selection” switch is operated. Start the playback process. Thus, automatic accompaniment from the intro section of the selected style is started, and the process returns to step S7 of the main process (FIG. 4).
[0043]
[Reproduction processing]
FIG. 6 is a flowchart showing an operation example of the reproduction processing according to the embodiment of the present invention. This reproduction process can be started only during automatic accompaniment [while reproduction process interruption is permitted (S4, S67)], and is started every predetermined timing (MIDI clock timing) by the timer 2. In this example, the automatic accompaniment is always started from the reproduction of the intro section of the accompaniment style data, and the reproduction of the intro section data ends (the intro section data is read up to the last data). Then, the main reproduction starts automatically (the reading position is set at the head of the main section data). The main section data is repeatedly reproduced until an automatic accompaniment end instruction is issued. When the automatic accompaniment end instruction is issued, the main section data is switched from main section data to ending section data.
[0044]
When the reproduction processing flow starts, in the first step P1, an event to be processed at the current timing is processed at an event after the current reading position, and the reading position is moved to the next event position. Here, the rhythm event is sounded as it is, and the chord and bass events are sounded after pitch conversion based on the chord specified at that time. In the next step P2, it is determined whether or not the playback of the ending section has ended. If the playback of the ending section has not ended yet or the section being played is not ending (NO), The reproduction process is terminated, and the process of step P1 is repeated every time the next timing comes.
[0045]
Then, when the performance progresses and the reproduction of the ending section data is completed, the process proceeds from step P2 to step P3, the reproduction process is stopped to terminate the automatic accompaniment, and the reading position is set to the intro section data of the selected style. Set to the beginning of. As described above, normally, when the reproduction of the ending section data is finished, the automatic accompaniment by the reproduction process is stopped, and the reading position is set to the head of the intro section data of the selected style at that time.
[0046]
[Various Embodiments]
As mentioned above, although this invention was demonstrated about one Example, this invention can be implemented in a various aspect. For example, the specific section where the standby for the synchro start is set is an intro section in the embodiment, but may be other sections such as a main section and an ending section as necessary. Further, a specific section for setting the synchro start standby may be changed by initial setting or the like.
[0047]
In the embodiment, the operation of the “start / stop” switch is ignored during standby for the synchro start [S6; S61 to S66 (NO)], but the “start / stop” switch is operated during the standby for the synchro start. Then, automatic accompaniment may be started (reproduction processing is activated).
