TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic musical instrument having a volume adjustment function for performing volume adjustment such as fade-in and / or fade-out when performing automatic accompaniment.
[0002]
[Prior art]
Recent electronic musical instruments have a fade-out function that gradually attenuates the volume at the end of a song, and a fade-in function that gradually increases the volume by crossing the volume change together with the fade-out function at the joint of the song. Many have a function (this function is simply used at the beginning of a song). These volume adjustment functions are used particularly at the start, middle, or end of an automatic accompaniment performance of an electronic musical instrument.
[0003]
In these electronic musical instruments, when a fade-in SW (a switch for starting a fade-in) and a fade-out SW (a switch for starting a fade-out) are provided on the panel as panel SWs, the selection is made by pressing the fade-in SW. The fade-in for changing the volume of the middle automatic accompaniment performance from 0 to the value set by the volume is started, and the execution of the fade-in process is completed over a predetermined time. When the fade-out SW is pressed, the fade-out for changing the volume of the performance of the automatic accompaniment during the performance to 0 is started, and the execution of the fade-out process is completed over a predetermined time.
[0004]
Further, when a switch that functions as a fade-in switch and a fade-out switch is provided on the panel of the electronic musical instrument, the switch is pressed once while the automatic accompaniment is stopped, so that the fade-in process is performed, and the automatic accompaniment performance is performed. By pressing the SW again, the fade-out processing is executed.
[0005]
[Problems to be solved by the invention]
Normally, in these electronic musical instruments, the time required for volume adjustment such as fade-in / fade-out is preset (by the manufacturer) by default, and only one type of time is prepared (for example, the fade-in time is 4 times). Seconds, fade-out time is about 6 seconds).
[0006]
However, since the ending of the performance or the fade-out function used between the performances is a function for giving an effect to the performance, it is better to be able to set the time for adjusting the volume according to the tune. This is the same for the fade-in function. When only one type of time is set as described above, there is a problem that such time cannot be properly used.
[0007]
The present invention has been made in order to solve the above-described problems, and provides a plurality of work times for volume adjustment including a setting in advance or by a user, and allows a user to adjust the volume in accordance with the tune. To provide an electronic musical instrument having a volume control function that allows the user to freely select a working time for the electronic musical instrument.

[0025]
FIG. 3 is a flowchart showing a basic processing routine of the electronic musical instrument. That is, when the power is turned on, an initialization process is performed (step S101). Next, a panel switch event of the panel operation unit 105 is detected (step S102). When a panel switch event is detected (Step S102; Yes), panel event processing is performed (Step S103). Conversely, if no panel switch event is detected (step S102; No), after the panel event processing is completed, an event of a key switch of the keyboard unit 104 is detected (step S104). When an event of a key switch is detected (Step S104; Yes), key event processing is performed (Step S105). Conversely, if no key switch event is detected (step S104; No), the key accompaniment process is terminated, and then the automatic accompaniment playback process is performed (step S106). Thereafter, the process returns to step S102.
[0026]
FIGS. 4 and 5 are flowcharts showing a processing flow in the case where the fade-out processing is executed during the automatic accompaniment processing in the panel event processing in step S103 according to the conventional configuration of the electronic musical instrument.
[0027]
First, it is detected whether or not the automatic accompaniment start switch has been turned on (step S201). If it has been turned on (step S201; Yes), the automatic accompaniment process is executed (step S202), and the automatic accompaniment operation is being performed. The flag Auto is set (step S203). After the execution of this step 203 or when it has not been turned on in step S201 (step S201; No), it is detected whether or not the automatic accompaniment operation flag Auto is set (step S204). If the automatic accompaniment operation flag Auto is not set (step S204; No), the process proceeds to step S209, which will be described later, and performs other panel SW processing. On the other hand, when the automatic accompaniment operation flag Auto is set (step S204; Yes), it is detected whether or not the automatic accompaniment stop SW is ON (step S205). If the automatic accompaniment stop SW has not been turned ON (step S205; No), the process proceeds to step S301 and subsequent steps, which will be described later. On the other hand, when the automatic accompaniment stop SW is ON (step S205; Yes), the automatic accompaniment process is stopped (step S206), and both the automatic accompaniment operation flag Auto and the fade-out process flag Fout are turned OFF (step S205). S207, S208). Thereafter, other panel SW processing is performed (step S209).
[0028]
As described above, when the automatic accompaniment stop SW is not ON (step S205; No), it is detected whether or not the fade-out processing flag Fout is ON (step S301). If the in-fade-out processing flag Fout is not ON (step S301; No), the process proceeds to step S305 described later. On the other hand, when the flag Fout during the fade-out process is ON (step S301; Yes), it is detected whether the fade-out process is completed (step S302). If the fade-out processing has not been completed (step S302; No), the other panel SW processing in step S209 is performed. When the fade-out processing is completed (step S302; Yes), both the automatic accompaniment operation flag Auto and the fade-out processing flag Fout are turned off (steps S303 and S304). Thereafter, other panel SW processing is performed (step S209).
[0029]
If the above-mentioned fade-out processing flag Fout is not ON (step S301; No), it is detected whether or not there is an automatic accompaniment change event (step S305). If there is an automatic accompaniment change event (step S305; Yes), the change is made to the automatic accompaniment with the change event (step S306). Then, the process proceeds to the other panel SW process execution process of step S209.
[0030]
If there is no automatic accompaniment change event (step S305; No), it is detected whether or not there is a fade-out SW on event (step S307). If there is a fade-out SW ON event (step S307; Yes), a fade-out processing routine is executed (step S308), and then the fade-out processing flag Fout is turned ON (step S309). After that, the flow shifts to the other panel SW processing execution processing in step S209. On the other hand, when there is no fade-out SW on event (step S307; No), the process shifts to another panel SW process execution process of step S209.
[0031]
The above processing is a processing flow when the fade-out processing is executed during the automatic accompaniment processing in the case of the conventional configuration. In the fade-out processing routine of step S308, the fade-out processing time is fixed to one. The user cannot freely set the processing time as needed.
[0032]
On the other hand, FIGS. 6 and 7 show the processing flow when the fade-out processing is executed during the automatic accompaniment processing by the above-described embodiment of the present invention in which two types of fade-out processing work time are prepared. It is a flowchart.
[0033]
In these figures, since the same processing is performed in steps S201 to S209, the details are omitted. On the other hand, if the automatic accompaniment stop SW is not ON in step S205 (step S205; No), it is detected whether or not the fade-out processing flag Fout is ON (step S401). If the in-fade-out processing flag Fout is not ON (step S401; No), the process proceeds to step S407 described later. On the other hand, when the fade-out processing flag Fout is ON (step S401; Yes), it is detected whether or not there is a fade-out SW ON event (step S402). If there is a fade-out SW on event (step S402; Yes), a fade-out processing routine 2 is executed (step S403). After execution of this process or when there is no fade-out SW on event (step S402; No), it is detected whether or not the fade-out process has been completed (step S404). If the fade-out process has not been completed (step S404; No), the other panel SW process of step S209 is performed. When the fade-out processing is completed (Step S404; Yes), both the automatic accompaniment operation flag Auto and the fade-out processing flag Fout are turned off (Steps S405 and S406). After that, the flow shifts to the other panel SW processing execution processing in step S209.
[0034]
If the above-described fade-out processing flag Fout is not ON (step S401; No), it is detected whether or not there is an automatic accompaniment change event (step S407). If there is an automatic accompaniment change event (step S407; Yes), the change is made to the automatic accompaniment with the change event (step S408). Then, the process proceeds to the other panel SW process execution process of step S209.
[0035]
If there is no automatic accompaniment change event (step S407; No), it is detected whether or not there is a fade-out SW on event (step S409). If there is a fade-out SW on event (step S409; Yes), the fade-out processing routine 1 is executed (step S410), and then the fade-out processing flag Fout is turned on (step S411). After that, the flow shifts to the other panel SW processing execution processing in step S209. On the other hand, if there is no fade-out SW on event (step S409; No), the process shifts to another panel SW process execution process of step S209.
[0036]
In the above processing, when there is an ON event of the fade-out SW during the automatic accompaniment performance (when the fade-out SW is pressed once), the fade-out processing routine 1 is executed (step S410). If there is a fade-out SW on event again during execution of the fade-out processing routine 1 (when the fade-out SW is further pressed), the fade-out processing routine 2 is executed (step S403).
[0037]
As described above, unlike the conventional case, two default fade-out processing operation times are prepared, and the user can selectively use them as needed. This advantage is, for example, when performing continuous performance by switching automatic accompaniments with different tempos, when performing fade-out processing during that time, [automatic accompaniment with a high tempo] → (fading out for a short time) → [automatic accompaniment with a slow tempo] → (Long time fade-out) → [Fast tempo automatic accompaniment] allows you to select the fade-out time in consideration of the effect on the performance, thereby increasing the expressive power of the performance.
[0038]
Further, FIGS. 8, 9 and 10 show a processing flow when the fade-out processing is executed during the automatic accompaniment processing by the configuration of the embodiment of the present invention in which two or more types of the fade-out processing work time are prepared. It is a flowchart shown.
[0039]
In these figures, steps S201 to S209 perform the same processing as before, and thus the details are omitted. On the other hand, if the automatic accompaniment stop SW is not ON in step S205 (step S205; No), it is detected whether or not the fade-out processing flag Fout is ON (step S501). If the fade-out processing flag Fout is not ON (step S501; No), the process proceeds to step S509 described below. On the other hand, when the fade-out processing flag Fout is ON (step S501; Yes), it is detected whether or not there is a fade-out SW ON event (step S502). If there is a fade-out SW on event (step S502; Yes), the fade-out counter Fcnt is incremented (step S503), and a fade-out processing routine (a fade-out processing routine corresponding to a new Fcnt other than Fcnt = 1) is executed (step S502). S504). After execution of this process or when there is no fade-out SW on event (step S502; No), it is detected whether or not the fade-out process has been completed (step S505). If the fade-out processing has not been completed (step S505; No), the other panel SW processing in step S209 is performed. When the fade-out processing is completed (Step S505; Yes), both the automatic accompaniment operation flag Auto and the fade-out processing flag Fout are turned off (Steps S506 and S507), and the fade-out counter Fcnt is returned to 0 (Step S508). After that, the flow shifts to the other panel SW processing execution processing in step S209.
[0040]
If the above-mentioned fade-out processing flag Fout is not ON (step S501; No), it is detected whether or not there is an automatic accompaniment change event (step S509). If there is an automatic accompaniment change event (step S509; Yes), the change is made to the automatic accompaniment with the change event (step S510). Then, the process proceeds to the other panel SW process execution process of step S209.
[0041]
If there is no automatic accompaniment change event (step S509; No), it is detected whether there is a fade-out SW on event (step S511). If there is a fade-out SW on event (Step S511; Yes), the fade-out counter Fcnt is set to 1 (Step S512), and a fade-out processing routine (a fade-out processing routine corresponding to Fcnt = 1) is executed (Step S513). Thereafter, the flag Fout during the fade-out process is turned ON (step S514), and the process proceeds to the other panel SW process of step S209. On the other hand, when there is no fade-out SW on event (step S511; No), the process shifts to another panel SW process execution process of step S209.
[0042]
FIG. 10 shows a processing flow of the fade-out processing routine in steps S504 and S513. As shown in the figure, first, it is detected whether or not the fade-out counter Fcnt is 1 (step S521). If the counter Fcnt is 1 (step S521; Yes), the fade-out processing work time is set to 5 seconds. Then, a fade-out process is performed (step S522). If the counter Fcnt is not 1 (step S521; No), it is detected whether or not the fade-out counter Fcnt is 2 (step S523). If the counter Fcnt is 2 (step S523; Yes), The fade-out processing work time is set to 10 seconds to perform the fade-out processing (step S524). Thereafter, the above processing is repeated, and the last work time setting No. n. Here also, it is detected whether or not the fade-out counter Fcnt is n (step S525). If the counter Fcnt is n (step S525; Yes), the fade-out processing work time is set to n × 5 seconds and fade-out is performed. The process is performed (Step S526).
[0043]
In the above processing, when there is an ON event of the fade-out SW during the automatic accompaniment performance (when the fade-out SW is pressed once), the fade-out processing routine is executed for five seconds (step S511). During the execution of the fade-out processing routine, if there is a fade-out SW on event again (when the fade-out SW is further pressed), the fade-out processing routine is executed for 10 seconds (step S504). Thereafter, in the same manner, Fcnt is counted up by the counter 3a by the number of times the fade-out SW is turned on, and the fade-out process is executed in the fade-out process routine in a work time corresponding to the number of times the fade-out SW is pressed. When the fade-out SW is pressed for a time equal to or longer than the preset fade-out processing work time, the processing is performed with the fade-out counter Fcnt = n.
[0044]
FIG. 11 is a functional block diagram illustrating a configuration according to another embodiment of the present invention. The configuration includes a volume adjustment unit 1b that performs volume adjustment, an adjustment instruction unit 2b that instructs the volume adjustment, and a volume adjustment unit. Counter 3b for counting the number of times of instruction, time setting means 6 for setting a work time for volume adjustment, storage means 4b for storing a work time for volume adjustment, and work in accordance with the counted number. And control means 5b for reading the time and adjusting the volume over the working time.
[0045]
The configuration of the volume adjustment unit 1b, the adjustment instruction unit 2b, the counter 3b, and the control unit 5b is the same as the configuration of the volume adjustment unit 1a, the adjustment instruction unit 2a, the counter 3a, and the control unit 5a in the embodiment. The details are omitted because they are the same.
[0046]
The time setting means 6 includes at least the CPU 101 and a panel operation unit 105 having a panel scan circuit 105a, and can set a work time for volume adjustment.
[0047]
The storage unit 4b has substantially the same configuration as the storage unit 4a of the above-described embodiment, but includes a RAM 102. In this configuration, only the work time set by the time setting unit 6 is stored. It has become. However, the configuration may be such that both the work time set by the time setting means 6 and the work time set in advance are stored (in that case, the work time is constituted by the ROM 103 and the RAM 102).
[0048]
FIG. 12 shows a display screen of the panel operation when the various function setting mode is entered in the panel operation processing and the fade-out operation time is set by the time setting means 6. First, as shown in FIG. 7A, a fade-out number input screen is displayed, and an appropriate numerical value is input using a numeric keypad or an increment dial. Then, a fade-out time input screen shown in FIG. 3B is displayed (in this case, the fade-out number is input as 1), and an appropriate numerical value is input using the numeric keypad or the like (unit is seconds). After that, a confirmation screen for confirming the input so far is displayed as shown in FIG. If the displayed content is acceptable, the cursor is located at Y by default, so the enter key is pressed. To change the displayed content, move the cursor to N using the arrow keys and press the enter key. By repeating the above operation a plurality of times, a plurality of fade-out processing operation times can be set. The number of fade-out numbers that can be set is determined in advance by the capacity of the RAM 102 of each model. Therefore, even if an attempt is made to input more than the fade-out number, it is not accepted.
[0049]
In the above processing configuration, when two fade-out numbers are set, processing is performed in the same processing flow as in FIGS. 6 and 7, and when a larger number is set, FIGS. The processing is performed in the same processing flow as in step 10.
[0050]
In each of the above-described two embodiments, the fade-out process is described in detail in FIGS. 6, 7, 8, 9, and 10, but the fade-in process is similarly performed. become. That is, if there is an ON event of the fade-in SW after the automatic accompaniment is selected (when the fade-in SW is pressed once), the fade-in processing routine 1 is executed. During the execution of the fade-in processing routine 1, if there is a fade-in SW ON event again (when the fade-in SW is further pressed), the fade-in processing routine 2 is executed. Alternatively, when there is an ON event of the fade-in SW after the automatic accompaniment is selected (when the fade-in SW is pressed once), the fade-in processing routine is executed for four seconds. During the execution of the fade-in processing routine, if there is a fade-in SW ON event again (when the fade-in SW is further pressed), the fade-in processing routine is executed over 6 seconds. Further, similarly, Fcnt is counted up by the counter 3a or 3b by the number of times the fade-in SW is turned on, and the fade-in process is executed in the fade-in process routine by taking a work time corresponding to the number of times the switch is pressed.
