Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for allowing a user to easily obtain a desired musical sound.

[0002]

2. Description of the Related Art In recent years,
For example, electronic musical instruments have become multifunctional and have various functions. To give a concrete example of the function,
An automatic performance function (here, it is a function including an automatic accompaniment function), a composition function for creating a music to be automatically performed, a multi-sound source function, and the like. Recently, most electronic musical instruments are MID
It is a model compatible with I (Musical Instrument Digital Interface). This MIDI is a standard for transmitting music information between different devices.

The user can compose music by using the composition function. This composition is performed, for example, by arranging note data (event data) consisting of pitches of musical tones, sounding start timings, and sounding durations (gate times) in a desired order of sounding.

In the composition function and the like, it is possible to set parameters relating to the entire performance such as tone color and sound effect. However, the parameter setting is, for example, after setting a certain parameter,
In order to set other parameters, each parameter had to be set independently. Also,
For the setting of one parameter, for example, after inputting (designating) the setting, it was necessary to confirm the setting as the setting of the parameter. From these things, the user can set (change) the parameters.
In order to do so, there has been a problem that complicated operations must be performed.

In an electronic musical instrument having a multi-tone generator function, parameters can be arbitrarily set for each track (channel). Therefore, in this case, the above problem becomes more serious. The problem of operability in setting this parameter is, regardless of the difference in function,
This is caused by the ability to set parameters.

By the way, in the automatic performance function,
A function has been installed so that a user can easily obtain a desired sound. The function is, for example, a function of automatically preparing a music with a sound desired by the user by preparing a plurality of options for designating a performance form of the music and allowing the user to select one of the options. Is. This function will be called a band making function here.

In the band make function, usually, a plurality of selection items having a plurality of options are prepared so that the user can be provided with various performance forms, and for each selection item, one option is selected by the user. I am trying to make it.

[0008] Normally, the user cannot immediately select a combination of options for each of the selection items to obtain a desired sound. Whether or not a desired sound can be obtained in a specified performance mode by a combination of options needs to automatically play a musical piece in the actually specified performance mode. From this, the user can repeatedly listen to the music by changing the combination of the options of each item, and listen to and compare the sound of the music obtained by each combination,
I was looking for a combination that gave me the desired sound.

However, in order to listen to the above-mentioned music, after designating the choices of each selection item, first, by instructing the reproduction thereof by operating a predetermined operator, and confirming its sound, I had to give instructions to finish the playback. To audition the song,
Since the user has to perform complicated operations,
It took a long time to find a combination of options that gave the desired sound.

An object of the present invention is to facilitate setting of parameters and change of the set contents. Another object is to facilitate the trial listening of music for automatic performance.

[0011]

A parameter control device according to a first aspect of the present invention is provided with a plurality of operators operated by a user, and responds to the contents of an operation performed by the user on the plurality of operators. Assuming that the setting of a plurality of parameters related to the pronunciation form of a musical sound is performed, the operation contents performed on a plurality of operators can be used for a plurality of parameters.
The recognition means for recognizing the setting content designated by the user for each parameter, and the setting content of one or more parameters recognized by the recognizing means when detecting an operation on a predetermined manipulator among a plurality of manipulators are applicable. And a control means for setting each as a parameter setting content.

As a result, for example, when the parameter setting contents are displayed on the screen and the parameter setting contents are designated on the screen, after the user arbitrarily changes the displayed setting contents of each parameter, , The changed settings can be confirmed at once.

A parameter control device according to a second aspect of the present invention comprises a plurality of operators operated by a user, and a tone generation mode of a musical tone is generated according to the contents of an operation performed by the user on the plurality of operators. Assuming that a plurality of parameters related to the above are set, the recognition means for recognizing the setting content of the parameter designated by the user from the operation content performed on the plurality of operators and the plurality of parameters are grouped in advance. Then, according to the change in the setting content recognized by the recognition means,
Control means for changing the setting content of each parameter in the group to which the parameter whose setting content has changed belongs.

As a result, the user can change the setting contents of the parameters of each track (channel), for example, by a single operation. The parameter control device is installed in a sequencer device, a tone generator device, an electronic musical instrument, or the like.

The automatic performance device of the present invention has a music data storage means for storing music data and a plurality of options.
Designation means for designating an option for each selection item for one or more selection items, and instruction means for instructing reproduction of the music data stored in the music data storage means,
And a reproducing means for reproducing a predetermined portion of the music data in a performance form based on the option for each selection item designated by the designating means when the reproduction of the music data is instructed by the instructing means.

Thus, for example, when a switch is provided as the above-mentioned instructing means, it is possible to perform a trial listening of the music reproduced according to the combination of the options selected for each selection item, simply by operating the switch. .

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a diagram showing an appearance of a system to which the first embodiment is applied. The first embodiment is realized as an electronic musical instrument 100. Electronic musical instrument 100
Is a keyboard 101 used to specify the musical sound to be pronounced,
A switch group 10 including the illustrated switches SW1 to SW9 and a plurality of other switches not particularly illustrated.
2 is provided. The electronic musical instrument 100 has a function of operating as a multi-tone sound source, a sequencer function (automatic performance function,
GM (general MID) with composition function
I) It is a compatible model.

A television 110 is connected to the electronic musical instrument 100. The electronic musical instrument 100 displays musical note data (event data), currently set sound source parameters, and the like on the screen of the television 110. It should be noted that the user changes the content displayed on the television 110 to the switch group 10
It can be designated by operating two predetermined switches.

Also, an external device such as a sequencer can be connected to the electronic musical instrument 100. This sequencer is, for example, a MIDI sequencer that sends music data for automatic performance to the outside in the form of MIDI data. When the MIDI data is sent from the sequencer, the electronic musical instrument 100 analyzes the MIDI data, pronounces musical tones, sets sound source parameters, etc. according to the analysis result, and displays the contents of the MIDI data on the television 110. Perform processing to display.

FIG. 2 is a block diagram of the configuration of the electronic musical instrument 100. As shown in FIG. 2, this electronic musical instrument 100
Is a CPU 20 that controls the entire musical instrument (and system)
1 and a ROM that stores various programs and control data
202, a RAM 203 mainly used as a work area by the CPU 201, the keyboard 101 and the switch group 102 described above, an image data output unit 204 for outputting image data for displaying an image on the screen of the television 110,
The MI of the sound system 205 that produces a musical tone according to the pronunciation command sent from the CPU 201 and the external device.
MIDI interface 20 for exchanging DI data
6 is provided.

The general operation of the above configuration will be described. The CPU 201 controls the operation of the entire musical instrument 100 based on the control program stored in the ROM 202, and thereby controls the operation of the entire system shown in FIG. 1.

When the user operates the keyboard 101, the CPU
The 201 identifies the operated key, obtains the speed (velocity) when the key is operated, generates a pronunciation command according to the operation content of the user, and outputs this to the sound system 205. .

Although not particularly shown, the sound system 205 includes, for example, a waveform ROM storing various tone waveform data, a sound source section for reading the waveform data from the waveform ROM, and a sound effect for the waveform data read by the sound source section. An analog waveform (musical sound) that is D / A converted from the added effector and digital waveform data output from the effector.
It is composed of a D / A converter that outputs a signal and a speaker that produces a musical sound by the waveform signal output by the D / A converter. By pronouncing a musical tone according to the pronunciation command input from the CPU 201, the musical tone is pronounced according to the operation performed on the keyboard 101 by the user.

The CPU 201 uses the sound system 2
In addition to outputting a sounding command to 05, sound source parameters that characterize the tones to be sounded are set. The sound source parameter is set when the user operates a predetermined switch of the switch group 102 or when the MIDI interface 206 receives MIDI data specifying the sound source parameter from an external device. Note that the sound source parameter is the type of waveform data (corresponding to a tone color) read from the waveform ROM, the type of acoustic effect added by the effector,
And its depth, volume, bread, etc.

MIDI interface 206 is MID
When the I data is received, the CPU 102 determines that MI
In addition to generating a pronunciation command according to the contents of the DI data and outputting it to the sound system 205 and setting sound source parameters, the contents of the MIDI data are displayed on the television 110 and MIDI data according to the user's designation. Is recorded in the RAM 203.

The display of images on the television 110 is performed as follows. For example, as mentioned above, MIDI
When displaying the MIDI data received by the interface 206, the CPU 201 analyzes the MIDI data and specifies the image data necessary for displaying the contents. After that, the specified image data is stored in the ROM 20.
The data is read from the data No. 2, processed as needed, and output to the image data output unit 204. In addition to this image data, the CPU 201 outputs coordinate data designating a position where the image data is displayed to the image data output unit 204.

The image data output unit 204 outputs the image data to the television 110 so that the image data is displayed at the display position indicated by the coordinate data. This image data is output to the television 110 in the form of a video composite signal based on the NTSC system for each operation line in correspondence with the screen display system of the television 110. As a result, MIDI data is displayed on the display screen of the television 110 in a preset display format.

On the other hand, the RAM 2 for the received MIDI data
The recording to 03 is performed as follows. RAM 20
A recording area (music data storage area) for recording music data is assigned to 3, and this recording area is divided into a plurality of recording target tracks. The recording target track is
The user operates the switch group 102 in advance to specify it. M
The recording of the IDI data in the RAM 203 is performed by sequentially writing the event data sent as a channel message in the MIDI data in the recording target track on the music data recording area of the RAM 203 designated by the user together with its input timing.

FIG. 3 shows the television 1 when the mixer mode is set.
FIG. 10 is an explanatory diagram of a mixer mode screen displayed in 10. The electronic musical instrument 100 has a function of operating as a multi-tone sound source, and can set a tone color, a volume (volume), an effect, etc. for each track. The mixer mode screen shown in FIG. 3 represents the sound source parameters for reproducing the music data stored in each track of the music data storage area of the RAM 203 in a table format. Further, on this mixer display screen, when the MIDI interface 206 receives MIDI data, the channel is regarded as a track, and the setting contents of the sound source parameters designated for each channel are displayed.

The settings of the sound source parameters displayed on the mixer mode screen can be changed. For example, when changing the setting of the sound source parameter belonging to each track on the music data storage area of the RAM 203, the CPU 2
01 reads the setting information from the RAM 203,
It is displayed on the television 110 in the form of the mixer mode screen of FIG. On the mixer mode screen, a cursor CR is displayed as shown in FIG. The user selects the upper switch S
By operating the cursor key composed of W6, the lower switch SW7, the left switch SW8, and the right switch SW9,
After moving the cursor CR to the column displaying the parameter whose setting you want to change, press the switch SW4 or SW.
By operating 5, the parameter is changed to a desired value. The switches SW4 and SW5 are switches for designating increase / decrease of the value of the parameter. User switches S
When W4 is operated, its value decreases in sequence and the switch SW
When 5 is operated, its value increases sequentially.

In this way, after changing the displayed value of the parameter to a desired value, the switch SW2 or SW3 is operated. As a result, the setting content of the parameter whose value has been changed is confirmed, and the setting content is changed to that value. Details of this will be described later.

As described above, the mixer mode is a mode in which the setting state of the sound source parameter of each track (channel) is displayed, the setting state of the sound source parameter is notified to the user, and the setting state can be changed. is there. This mixer mode allows the user to effectively function the electronic musical instrument 100 as a multi-tone sound source.

The music (event) data recorded in the RAM 203 can be edited. CPU 20
1 reads the music data (event) recorded in a desired track on the music data recording area of the RAM 203 according to the contents designated by the user in the switch group 102, and displays it on the television 110 in the form of, for example, a notation. Let The user can use the switch group 102 to insert, delete, move, copy, etc., music (event) data with respect to music (event) data displayed on the television 110.

The result of editing by the user and the result of changing the sound source parameter as described above are stored in the RAM 2
This is reflected in the content of the music data in the music data recording area No. 03, or in the automatic performance by the MIDI data being received.

To reproduce the music data in the music data recording area of the RAM 203, the CPU 201 sequentially reads out the event data from the reproduction target track in the storage area, and creates a sounding command for generating a musical sound with the read event data, It is performed by outputting it to the sound system 205. As a result, the automatic performance is performed in the same manner as when MIDI data is received.

The above is the configuration of the electronic musical instrument 100 and the general operation of each unit. Next, the CPU 201 causes the ROM 20 to
Various processes realized as an operation of executing the control program stored in No. 2 will be described with reference to FIGS.

First, the overall processing will be described with reference to the operation flowchart shown in FIG. In particular, when a power switch (not shown) is turned on (on), first, in step 401, initial processing such as clearing the register in the CPU 201 and the work area of the RAM 203 and initial setting is performed. When this initial process is completed, the process proceeds to step 402.

In step 402, a switch process is carried out for responding to the contents of the operation performed on the switch group 102 by the user. In the following step 403, other processing such as a keyboard processing for producing a musical sound according to the operation content performed by the user on the keyboard 101 is executed, and thereafter
The process returns to step 402.

As described above, by repeating the processing loop of steps 402 to 403, the user can switch group 1
02, the electronic musical instrument 100 operates in response to an operation performed on the keyboard 101 or the like.

Next, the switch processing in step 402 will be described in detail with reference to the operation flowchart shown in FIG. First, in step 501, it is determined whether the switch SW1 is turned on. Switch SW1
Is a switch for setting the mixer mode.
If the user operates this switch SW1 to set the mixer mode, the determination is YES and step 5
The processing moves to 02. Otherwise, the decision is N
When it becomes O, the process proceeds to step 503.

In step 502, a mixer mode process for realizing the function of the set mixer mode is executed. Then, the process proceeds to step 503. Details of this mixer mode processing will be described later.

At step 503, other processing corresponding to the operation performed by the user on the other switches of the switch group 102 is executed. When this other process ends, the series of processes also ends here, and then step 40 in FIG.
The other processing of No. 3 is executed.

FIG. 6 is an operation flowchart of the mixer mode processing in step 502. The mixer mode processing will be described in detail with reference to FIG. In the mixer mode, the mixer mode screen of FIG.
It is displayed on 10. The sound source parameters are set for each mode. The sound source parameter displayed on the mixer mode screen can be specified by operating the switch group 102, although a detailed description is omitted. As described above, the user can change each value of the sound source parameter displayed on the mixer mode screen by operating the switch group 102. These functions are realized by executing this mixer mode processing.

First, in step 601, the register of the CPU 201, which is associated with the setting of the mixer mode,
Initial processing such as clearing the work area of the RAM 203 and initial setting is performed. In this initial process, a process of displaying the sound source parameter specified by the user on the television 110 in the form of the mixer mode screen of FIG. 3 is also performed.

In the subsequent step 602, mixer mode switch processing for changing the setting contents of the sound source parameter is performed in response to the user's operation on the switch group 102. In a succeeding step 603, in response to the user's operation on the keyboard 101, a tone generation command is generated, and other processing including keyboard processing for transmitting it to the sound system 205 is performed. Thereafter, a series of processing ends.

FIG. 7 is an operation flowchart of the mixer mode switch process in step 602 of FIG.
The processing operation will be described in detail with reference to FIG. 7.
In the first embodiment, setting contents such as tone color, volume and effect are displayed as sound source parameters on the mixer mode screen of FIG. For these settings, move the cursor CR to the field where they are displayed and press the switch S
It can be changed by operating W4 or SW5.

The setting contents changed by operating the switch SW4 or SW5 are only the contents displayed. The changed setting content is confirmed by operating the switch SW2 or SW3, and is reflected in the actual sound source parameter.

Conventionally, the sound source parameters have been changed individually. Therefore, to change the setting content of one sound source parameter, first change the setting content, and then
It is necessary to perform a two-step operation of reflecting the changed setting contents, and the operation therefor is very complicated.

In the first embodiment, by confirming the change of the setting contents for each kind of the sound source parameter, the complicated operation as described above is avoided and the operability is improved. . Confirmation of the changed setting contents is realized by executing this mixer mode switch process.

In the mixer mode switch process of FIG. 7, a process of changing the displayed setting contents is performed in response to the operation of the switches SW4 and SW5. However, the process of changing the setting contents is not performed. It is omitted because it is not particularly important.

First, in step 701, the switch SW
It is determined whether 2 is turned on. This switch SW2
Is a switch for instructing the confirmation of the changed setting content, as described above. When the user operates the switch SW2, that is, when the user gives an instruction to confirm the changed setting content, the determination becomes YES, and the process proceeds to step 702. Otherwise, the determination is no and the process moves to step 706.

In step 702, a process for determining the range for confirming the setting contents is executed. In the first embodiment, the setting contents of the sound source parameter of each track are fixed for each kind of sound source parameter. From this, in step 702, the cursor C is moved to the recording start track of the variable indicating the head track of the range to be determined.
The track number where R is currently displayed (currently selected track) is moved to the recording end track of the variable indicating the end track of the range. The track number where the cursor CR is currently displayed (here, the sound source parameter of only one track). Of the currently selected track) is substituted into the currently processed track of the variable indicating the track number for which the currently set content is to be confirmed. The above variables are variables stored in the register in the CPU 201 or the RAM 203.

In step 703 following step 702, a process for recording the setting contents displayed on the track indicated by the current processing track is performed on the track indicated by the current processing track on the music data recording area of the RAM 203. As a result, the displayed setting contents are confirmed and the changes to the setting contents are reflected. Note that the sound source parameter whose setting content is fixed at this time is the sound source parameter of the line in which the cursor CR is displayed.

In step 704 following step 703, it is determined whether the value of the current processing track is equal to the value of the recording end track. Here, since the setting contents are fixed only for the currently selected track, the determination is YE.
S is reached, and a series of processing is ended here.

As described above, if NO in step 701, the process of step 706 is executed.
In step 706, it is determined whether the switch SW3 has been turned on. The switch SW3 is, as described above,
This is another switch for instructing to confirm the changed settings. When the user operates the switch SW3, that is, when the user gives an instruction to confirm the changed setting content, the determination becomes YES and the process proceeds to step 707. Otherwise, the determination is no and the process moves to step 708.

In step 707, a process for determining the range for confirming the setting contents is executed. This step 707
Then, the range is determined so that the setting contents of all the tracks (sound source parameters) where the cursor CR is currently displayed are fixed. Specifically, the beginning track number (leading track) is assigned to the recording start track, the final track is assigned to the recording end track, and the above-mentioned leading track is assigned to the current processing track. When the value substitution for each of these variables is completed, the process proceeds to step 703, and the setting contents within the determined range are confirmed. In the first embodiment, the value of the first track is 1, and the value of the last track is 16.

In step 704 following step 703, it is determined whether the value of the current processing track is equal to the value of the recording end track. If all the setting contents displayed within the range determined in step 702 are confirmed, the determination is YES, and the series of processing is ended here. Otherwise, the determination is no and step 705.
Move to the processing of. In this step 705, the currently processed track is incremented, and then step 7
Return to the process of 03.

By repeating the processing loop of steps 703 to 705, the setting contents of all the tracks are sequentially determined. If NO in step 706, the process of step 708 is executed next.

At step 708, it is determined whether or not any of the switches SW6 to SW9, which are cursor keys, is turned on. When the user moves the displayed cursor CR, the determination becomes YES and the process proceeds to step 709. If not, the determination is NO, and the series of processes ends here.

In step 709, a display position for moving the cursor CR is calculated according to the switch operated by the user, and a cursor moving process for displaying the cursor CR at the calculated display position is performed. After this process is completed
A series of processing ends.

The display position of the cursor CR to be moved by executing this cursor movement process is to specify the kind of the sound source parameter for fixing the setting contents and the track for fixing the setting contents when the switch SW2 is operated. become.

In the first embodiment, the setting contents are fixed by the type of the sound source parameter, but as shown in FIG. 3, the sound source parameters are collectively displayed in columns for each track on the mixer mode screen. Therefore, the setting contents may be fixed depending on the type of track. When the user operates a predetermined switch, the setting contents of the sound source parameter in the column where the cursor CR is displayed may be set as the setting contents of all tracks. Thus, the present invention can be applied flexibly.

Next, a second embodiment will be described. In the first embodiment, the setting contents can be fixed on all tracks by a single operation, but the setting contents must be changed for each sound source parameter of each track. Among the sound source parameters, there are also parameters such as volume that often change the setting contents similarly for each track. In the second embodiment, paying attention to this, the setting contents are decided.

Second Embodiment The configuration of the first embodiment is basically the same as that of the first embodiment. Therefore, the same reference numerals as in the first embodiment are used, and only the parts different from the first embodiment will be described.

FIG. 8 is an operation flowchart of the mixer mode switch process according to the second embodiment, which is executed as the process of step 602 of FIG. The processing operation will be described in detail with reference to FIG.

First, in step 801, the switch SW
It is determined whether 2 is turned on. This switch SW2
Is a switch for increasing the displayed setting content of the sound source parameter designated by the cursor CR by a predetermined unit value and instructing the confirmation of the setting content. When the user operates the switch SW2, the determination is YES and the process proceeds to step 702. Otherwise, the determination is no and the process moves to step 806.

At step 802, a process for determining the range for confirming the setting contents is executed. In the second embodiment, the range is all tracks. Therefore, in step 802, the beginning track number (starting track) is assigned to the recording start track, the final track is assigned to the recording end track, and the above-mentioned beginning track is assigned to the current processing track. When the value substitution for each of these variables is completed, the process proceeds to step 803. The value of the first track is 1, and the value of the last track is 16, as in the first embodiment.

In step 803, the unit value is added to the setting contents of the sound source parameter displayed at the track number indicated by the currently processed track, and the unit value is displayed.
A process of recording the added setting content in a corresponding track on the music data recording area of the RAM 203 is executed. As a result, the set contents, in which the unit value is added to the decided original setting contents, are displayed.

In step 804 following step 803, it is determined whether the value of the current processing track is equal to the value of the recording end track. When the setting contents of all the tracks are confirmed, the determination is YES, and the series of processing is ended here. Otherwise, the determination is no and the process moves to step 805. In step 805, the currently processed track is incremented, and then the process returns to step 803.

By repeating the processing loop of steps 803 to 805, the setting contents displayed within the range designated by the user are sequentially added and, at the same time, confirmed.

As described above, if NO in step 801, the process of step 806 is executed.
In step 806, it is determined whether the switch SW3 has been turned on. The switch SW3 is a switch for decreasing the displayed setting content of the sound source parameter designated by the cursor CR by a predetermined unit value and instructing the confirmation of the setting content. When the user operates the switch SW3, the determination is Y
It becomes ES and shifts to the processing of step 807. Otherwise, the determination is no and the process moves to step 811.

At step 807, a process for determining the range for confirming the setting contents is executed. Specifically, the leading track is assigned to the recording start track, the final track is assigned to the recording end track, and the leading track is assigned to the current processing track. When the value substitution for each of these variables is completed, the process proceeds to step 808.

In step 808, the unit value is subtracted from the setting content of the sound source parameter displayed on the track number indicated by the currently processed track, the unit value is displayed, and the subtracted setting content is stored in the music data recording area of the RAM 203. Perform the process of recording on the corresponding track above. As a result, the determined setting contents obtained by subtracting the unit value from the original setting contents are displayed.

In step 809 following step 808, it is determined whether or not the value of the current processing track is equal to the value of the recording end track. When the setting contents of all the tracks are confirmed, the determination is YES, and the series of processing is ended here. Otherwise, the determination is no and the process moves to step 810. In step 810, the currently processed track is incremented, and then the process returns to step 808.

By repeating the processing loop of steps 808 to 810, the setting contents displayed within the range designated by the user are successively subtracted, and at the same time, the setting contents are confirmed.

If NO is determined in step 806, the process of step 811 is executed next. Step 811
Then, it is determined whether or not any of the switches SW6 to SW9, which are cursor keys, is turned on. If the user moves the displayed cursor CR, the determination is YES.
Then, the process proceeds to step 812. If not, the determination is NO, and the series of processes ends here.

In step 812, the display position for moving the cursor CR is calculated according to the switch operated by the user, and the cursor moving process for displaying the cursor CR at the calculated display position is performed. After this process is completed
A series of processing ends.

By executing this cursor movement processing, the display position of the cursor CR to be moved specifies the type of the sound source parameter whose setting content is to be confirmed. In addition,
In the second embodiment, the setting content to be increased / decreased in each track is the setting content of the sound source parameter of the track itself. However, for example, the setting content of each track is set as the setting content of the track in which the cursor CR is displayed. Is also good. Further, the change and confirmation of the setting content may be performed not by the type of the sound source parameter as described above but by the track. Also, the setting contents of the parameters are shown in FIG.
Although it is displayed as a digital value as shown in, it may be displayed in an analog manner like a slider. The present invention does not limit the method of expressing the setting contents.

When the switch SW2 or SW3 is operated, the setting contents of the parameters on the mixer mode screen are changed and the changed setting contents are confirmed. Change,
You may make it determine separately. As described above, the present invention can be variously modified.

Next, a third embodiment will be described. Recently, sequencers and electronic musical instruments equipped with a band making function have been commercialized. The band making function is a function that allows the user to automatically perform a music piece in a desired performance mode by designating the rhythm and decoration of the music piece. In the third embodiment, the present invention is applied to an electronic musical instrument equipped with a band making function.

Like the second embodiment, the third embodiment is basically the same as the configuration of the first embodiment. Therefore, the same reference numerals as in the first embodiment are used, and only the parts different from the first embodiment will be described.

FIG. 9 is an explanatory diagram of a band make screen displayed on the television 110 when the band make mode is set. With reference to FIG. 9, a method of designating a performance form of a music piece (hereinafter, referred to as band make) according to the third embodiment will be described.

The band make mode is set by operating the switch SW1 shown in FIG. CPU2 in FIG.
01 detects that the switch SW1 is operated, the ROM 2
The image data is read from 02 and is output to the image data output unit 204 together with the coordinate data to display the band make screen of FIG.

In the lower part of the band make screen of FIG. 9, as the items to be selected by the user, the rhythm selection item M1, the selection item M2 relating to music decoration, etc., and the performer (band).
The selection item M3 of is displayed. A plurality of options are displayed in each of the selection items M1 to M3. The user selects a choice from among the selection items M1 to M3 to specify the performance form of the music, that is, perform band making.

Selection of the choices in each of the selection items M1 to M3 is performed using the cursor keys. Specifically, the left switch SW8 or the right switch SW9 is operated to move the cursor CR to the selection item for which an option is desired to be selected, and then the upper switch SW6 or the lower switch SW7 is operated to make the selection. Select the desired choice among the items. The option in each selection item thus selected is highlighted, for example, to notify the user that it is the currently selected option. In addition, M displayed above the band make screen of FIG.
EM is an illustration of members of each accompaniment part of the band selected by the user in the selection item M3.

The music data for automatic performance is stored in the ROM 202.
Stored in advance. When the CPU 201 detects the operation of the switch SW2 when the band make mode is set, the CPU 201 reads the corresponding music data from the ROM 202 based on the options of each selection item selected on the band make screen of FIG. 9, and stores the music data in the RAM 203. This is stored in the area and the sound source parameter of the sound system 205 is set. After that, the music data (event data) is sequentially read from the RAM 203 to generate a tone generation command, and the tone generation command is transmitted to the sound system 205, thereby performing an automatic performance in a performance mode specified by the user.

Next, various control processing operations executed in the third embodiment will be described in detail with reference to the operation flowcharts of FIGS. FIG. 10 is an operation flowchart of the switch process according to the third embodiment, which is executed as the process of step 402 of FIG. First, the switch process will be described with reference to FIG.

First, in step 1001, the switch S
It is determined whether W1 is turned on. The switch SW1 is
This is a switch for setting the band make mode.
When the user operates the switch SW1 to set the band make mode, the determination is YES, and the process proceeds to step 1002. Otherwise, the determination is no and the process moves to step 1003.

In step 1002, band make mode processing for realizing the set band make mode function is executed. Then, the process proceeds to step 1003. Details of this band make mode process will be described later.

In step 1003, the switch group 102
Other processing according to the operation performed by the user on the other switch is executed. When this other process ends,
Here, a series of processing is ended, and then, step 4 in FIG.
Other processing of 03 is executed.

FIG. 11 is an operation flowchart of the band make mode process of step 1002. The band make mode process will be described with reference to FIG. 11.

First, in step 1101, initial processing such as clearing the register of the CPU 201, the work area of the RAM 203, and initial setting is performed in accordance with the setting of the band make mode. In this initial processing, R
By reading the image data from the OM 202 and outputting the image data together with the coordinate data to the image data output unit 204, processing for displaying the band make screen shown in FIG. 9 is also performed.

Step 1102 following step 1101
Then, a band make mode switch process corresponding to the function at the time of setting the band make mode assigned to each switch of the switch group 102 is executed.

In the band make mode, each selection item M1
~ Audition of music automatically played by the combination of selections (selection contents) selected in M3 (pattern monitor)
You can do it. The pattern monitor starts when the user operates the switch SW1. The process of starting the pattern monitor is performed in the band make mode switch process. Details of the band make mode switch process will be described later.

Step 1103 following step 1102
Then, pattern monitor end processing for ending the pattern monitor is performed. The pattern monitor (listening) in the third embodiment has a predetermined range (pattern)
The music data is automatically played. The pattern monitor end process is a process for ending the pattern monitor depending on whether or not the automatic performance of the pattern has ended. The details will be described later.

Step 1104 following step 1103
Then, the music data is read from the RAM 203, a pronunciation command of the musical sound to be currently generated is generated, and the generated command is output to the sound system 205, thereby automatically performing
That is, the music reproduction processing for reproducing the music is executed. In the following step 1105, M of the MIDI interface 06
Other processing including processing for handling reception of IDI data is executed, and then a series of processing is ended.

FIG. 12 is an operation flowchart of the band make mode switch process of step 1102. The band make mode switch process will be described in detail with reference to FIG.

First, in step 1201, it is determined whether or not any of the switches SW6 to SW9, which are the up, down, left and right cursor keys, is turned on. When the user moves the displayed cursor CR, the determination becomes YES and the process proceeds to step 1202. Otherwise, the determination is no and the process moves to step 1203.

At step 1202, a display position for moving the cursor CR is calculated according to the switch operated by the user, and a cursor moving process for displaying the cursor CR at the calculated display position is performed. After this processing ends, a series of processing ends.

The display position of the cursor CR to be moved by executing this cursor moving process becomes the currently selected option. When the user operates the switch SW6 (upper switch) or the switch SW7 (lower switch), the cursor CR moves to a different option from the currently selected option.

In step 1203, it is determined whether the switch SW1 has been turned on. The switch SW1 is used to instruct the start of pattern monitoring (listening) when the band make mode is set. When the user operates this switch SW1 to instruct to start the pattern monitor (listening), the determination is YES and step 1
The process moves to 204. If not, the determination is NO, and the series of processes ends here.

At step 1204, it is determined whether the value of the pattern monitoring flag is 0 or not. The pattern monitoring flag is a variable held in the RAM 203.
The pattern monitoring flag indicates whether or not the pattern monitor (listening) is currently performed, and 1 is substituted when the pattern monitoring (listening) is being performed, and 0 is substituted when the pattern monitoring (listening) is not performed. If the pattern monitor (listening) is not currently performed, the determination in step 1204 is Y.
It becomes ES and shifts to the processing of step 1205. If not, the determination is NO, and the series of processes ends here.

At step 1205, each selection item M1.about.
Based on the option selected in M3 (see FIG. 9), pattern monitor start processing for starting reproduction of music data for pattern monitor (listening) is performed with the selected content.
After this processing ends, a series of processing ends.

FIG. 13 is an operation flowchart of the pattern monitor start processing in step 1205. The pattern monitor start processing will be described in detail with reference to FIG.

First, in step 1301, the RAM 20
An area for storing the music data of the selection specified by the user is secured in the music data storage area 3 and the ROM is stored therein.
A process of storing the music data read from 201 is performed. At this time, if other music data is stored in the music data storage area, a process of saving the music data in another storage area (buffer) is also performed.

The range of the music data to be pattern-monitored (listening) is predetermined. The range is indicated by the first measure of the range and the last measure (last measure) of the range. The music data stored in the RAM 203 in step 1301 is data within the range.

Step 1302 following step 1301
Now, the chord data of the bar before the bar currently played (current bar) is investigated. This is to specify the chord to be generated by the automatic performance. Following Step 1303
In 1305, the code is identified according to the investigation result.

In step 1303, it is determined whether or not there is code data before the current bar. Step 1303
When the code data is found as a result of the inspection of the code data of No., the determination is YES and Step 130
The process shifts to the process of No. 4. Otherwise, the determination is NO
Then, the process proceeds to step 1305.

In step 1304, the code data that is closest to the current measure (which is the first measure at this time) is set as the code data of the current measure. On the other hand, in step 1305, since the chord data cannot be found before the current measure, the preset (default) C tone code data is set as the chord data of the current measure.

The pattern monitor (listening) is performed by executing the processing of step 1304 or 1305.
The chord of the song to be played is confirmed. When these processes are completed, the process of step 1306 is executed next.

In step 1306, a combination of options selected by the user on the band make screen of FIG. 9 is fetched as screen selection information, and the sound system 205 is set according to the information.

Step 1307 following step 1306
Then, the reproduction start processing of the music data stored in the RAM 203 in step 1301 is performed. In this playback start process,
Initialization of a clock for managing the tone generation timing of this musical sound is performed. Moreover, 1 is also substituted for the pattern monitoring flag. By substituting 1 in the pattern monitoring flag, step 11 in FIG.
The music piece reproduction process No. 04 is actually executed. As a result, the music data for the pattern monitor (listening) is reproduced (automatically played).

FIG. 14 is an operation flowchart of the pattern monitor end processing in step 1103 of FIG.
Next, the pattern monitor end processing will be described in detail with reference to FIG.

First, in step 1401, it is determined whether or not the value of the pattern monitoring flag is 1. While the music data for pattern monitor (listening) is being reproduced (automatic performance), 1 is assigned to the in-pattern monitor flag. Therefore, if you are playing the song data,
The determination in step 1401 is YES and step 14
The processing moves to 02. Otherwise, the decision is N
It becomes O, and a series of processing is ended here.

In step 1402, it is determined whether or not the current bar exceeds the end bar of the reproduction range. When the music data in the range for pattern monitoring (listening) is reproduced, the determination is YES and the process proceeds to step 1403. If not, the determination is NO, and the series of processes ends here.

At step 1403, reproduction end processing is performed. In this playback end processing, the sound system 2
For example, the setting of the sound source parameter of 05 is returned to the original state.

Step 1404 following step 1403
Then, a process of restoring the data saved in the process of step 1301 of FIG. 13 to the original state is performed. In the subsequent step 1405, 0 is assigned to the pattern monitoring flag, and then the series of processing is ended.

As described above, in the third embodiment, only by operating the switch SW1, the music is reproduced in the performance mode designated in the band make mode. Since the music can be listened to by a simple operation, the user can quickly search for a combination that provides a desired sound from among a wide range of choices.

In the third embodiment, the switch for setting the band make mode is the same as the switch for instructing the reproduction of the music data, but these switches may be separate.

Next, a fourth embodiment will be described. In the third embodiment described above, the music can be listened to by a simple operation, but once the reproduction is started,
In order to listen to the music by using other combinations, it was necessary to wait until the reproduction of a predetermined range was completed. In many cases, the user only needs to listen to the first part of the music and the audition is sufficient. On the other hand, there are many cases where one trial listening is not enough.

In the former case, it takes time to find a desired combination. In the latter case, since it is necessary to instruct the reproduction of the music again after the reproduction of the music is ended, it is troublesome and the time for the instruction is wasted. The fourth embodiment is designed to avoid these problems.

Like the third embodiment, the fourth embodiment is basically the same as the configuration of the first embodiment. Therefore, the same reference numerals as in the first embodiment will be used to describe only the parts different from those in the third embodiment.

FIG. 15 is an operation flowchart of band make mode switch processing according to the fourth embodiment. This process is executed as the process of step 1102 in the band make mode process of FIG. The processing operation will be described in detail with reference to FIG.

First, in step 1501, it is determined whether or not any of the switches SW6 to SW9, which are the up, down, left and right cursor keys, is turned on. When the user moves the displayed cursor CR, the determination is yes and the process proceeds to step 1502. Otherwise, the determination is no and the process moves to step 1503. In step 1502, a display position for moving the cursor CR is calculated according to the switch operated by the user, and cursor movement processing for displaying the cursor CR at the calculated display position is performed. After this process is completed
A series of processing ends.

The display position of the cursor CR that is moved by executing this cursor moving process becomes the currently selected option. When the user operates the switch SW6 (upper switch) or the switch SW7 (lower switch), the cursor CR moves to a different option from the currently selected option.

In step 1503, it is determined whether the switch SW1 has been turned on. As will be described later, the switch SW1 is used to instruct the start and end of the pattern monitor (listening) when the band make mode is set. When the user operates this switch SW1, the determination becomes YES, and the process proceeds to step 1505. Otherwise, the determination is no and the process moves to step 1504.

At step 1504, when the music for the pattern monitor (listening) is being reproduced, the pattern monitor continuation processing for continuing the reproduction is executed. After this pattern monitor continuation process is completed, a series of processes is completed.

In step 1505, it is determined whether the value of the pattern monitoring flag is 0. When the pattern monitor (listening) is not performed, the determination is YES and the process proceeds to step 1506. Otherwise, the determination is no and the process moves to step 1507.

At step 1506, each selection item M1.about.
Based on the combination of the options (see FIG. 9) selected in M3, pattern monitor start processing for starting reproduction of music data for pattern monitor (listening) is performed with the combination contents. After this processing ends, a series of processing ends.

At step 1507, reproduction end processing is performed. In this playback end processing, the sound system 2
For example, the setting of the sound source parameter of 05 is returned to the original state.

Step 1508 following step 1507
Then, a process of restoring the data saved in the process of step 1301 of FIG. 13 to the original state is performed. In the subsequent step 1509, 0 is assigned to the pattern monitoring flag. Thereafter, a series of processing ends.

As described above, in the fourth embodiment, when the switch SW1 is operated to start the reproduction of the music, the reproduction of the music is repeatedly continued until the switch SW1 is operated again. Therefore, by operating the switch SW1 as necessary, the user can immediately end the reproduction of the music or continue the trial listening of the music. As a result, the user can search for a combination that provides the desired sound while checking the sounds obtained by each combination without performing a complicated and troublesome operation.

Next, the pattern monitor continuation processing of the above step 1504 will be described with reference to the operation flowchart thereof shown in FIG. First, step 1601
Then, it is determined whether or not the value of the pattern monitoring flag is 1. If music data is being reproduced, step 16
The determination of 01 is YES, and the process proceeds to step 1602. If not, the determination is NO, and the series of processes ends here.

At step 1602, it is determined whether or not the current bar exceeds the end bar of the reproduction range. When the music data in the pattern monitor (listening) range is reproduced, the determination is YES and the process proceeds to step 1603. If not, the determination is NO, and the series of processes ends here.

At step 1603, reproduction end processing is performed. In this playback end processing, the sound system 2
For example, the setting of the sound source parameter of 05 is returned to the original state.

Step 1604 following step 1603
Then, the process of returning the current measure to the start measure of the reproduction range is performed. In the subsequent step 1605, reproduction start processing for repeating reproduction of the music data is performed. In this reproduction start processing, initialization of a clock for managing the tone generation timing of this musical sound is performed. After the reproduction start process is completed, the series of processes is completed.

In the fourth embodiment, the switch S
The reproduction of the music data is repeated until W1 is operated, and the upper limit value for repeating the reproduction is set in advance. Even if the switch SW1 is not operated, the reproduction of the upper limit value is repeated, The audition may be ended. Further, although the start and the end of the trial listening of the music data are instructed by the same switch, these switches may be separate.

Although the present invention is applied to the electronic musical instrument 100 in the third and fourth embodiments, the application of the present invention is not limited to the electronic musical instrument. For example,
The present invention can be applied even to a device such as a sequencer that does not have a function of producing musical tones.

[0140]

As described above, the parameter control device of the present invention can reflect (determine) the setting contents designated by the user for each parameter at once as the setting contents of each parameter, so that a small number of operations are required. Can easily change (set) the parameter settings.
As a result, the setting contents of the parameters can be changed efficiently, and the time required for this can be shortened.

Further, the parameter control device of the present invention is
Since the change of the setting content for one parameter is reflected in the setting content of another parameter according to the content of the change, the same effect as above can be obtained. However, in some cases, the setting contents of the parameters can be changed very efficiently as compared with the above invention.

Further, since the automatic performance device of the present invention reproduces the music for trial listening in the performance mode designated by one option or a combination of a plurality of options in accordance with the operation of the switch or the like, The user can audition it with a simple operation. This makes it easy to find a playing style that provides the desired sound.
