Description

  The present invention relates to a program for realizing a control method for controlling an electronic music system including an electronic music device and a music control device for remotely controlling the electronic music device.

  2. Description of the Related Art An electronic music system including an electronic music device and a music control device that remotely controls the electronic music device has been known.

  For example, a PC (personal computer) in which DAW (digital audio workstation) software is installed and started is used as an electronic music device, and a compact physical controller including a single motor fader is used as a music control device. There is an electronic music system that uses a controller to control DAW software.

  Cubase (registered trademark) of STEINBERG, which is an example of DAW software, has a sequencer function and a mixer function. For example, each audio signal generated by reproducing each audio waveform recorded on each audio track by the sequencer function, Mixing can be performed by the mixer function. In addition, Cubase (registered trademark) can create a subtrack (automation) that sets the values of mixer channel parameters, etc. in time series for each audio track, and an automation subtrack is created for the audio track to be played. In this case, the automation subtrack is also played back in synchronization with the playback of the audio track.

  In addition, the STEINBERG Advanced Integration Controller CC121 (hereinafter referred to as “controller CC121”), which is an example of a physical controller, can switch audio tracks on the Cubase (registered trademark) side and is currently selected. When the audio track is switched to another audio track, the indicated position (fader position) of the motor fader is automatically moved from the current position to the position indicating the value set in the other audio track. (For example, refer to page 15 of Non-Patent Document 1).

  Furthermore, after assigning a part selected arbitrarily from various parameters on the Cubase (registered trademark) side to the controller CC121, the parameter is specified by pressing the button, and the knob is used to specify the parameter. There is also a function for setting parameter values (for example, see page 17 of Non-Patent Document 1).

  In the controller CC121, when a user operates a predetermined operator of the controller CC121 with one of various parameters on the Cubase (registered trademark) side specified in advance, any audio track is selected. However, there is also a function that changes the value of the one parameter regardless of the selection of the audio track (for example, see page 19 of Non-Patent Document 1).

CC121 Instruction Manual, 2008, Yamaha Corporation

  However, in the conventional music control apparatus, that is, the controller CC121, the parameters assigned to the motor faders, that is, the parameters that can be set by the motor faders are fixedly determined for any audio track (specifically, This is a volume parameter that defines the signal level when the audio signal of each audio track is input to the mixer), so the user has a desire to set different types of parameters for each audio track using the motor fader. Even so, I was unable to meet that demand. In particular, since it is not assumed that the motor fader is used in the sub-track, the motor fader is not used in setting the parameters in the sub-track.

  The controller CC121 assigns a desired parameter to a button, and then the value of the parameter assigned to the button can be set by operating the button and knob. This function is applied to the motor fader. Thus, an arbitrary parameter can be set using the motor fader. However, since it is necessary to complete the parameter assignment to the motor fader in advance, it is difficult to set the parameter type that is set in the motor fader each time the track or sub track is switched. It is.

  Furthermore, the controller CC121 can set the value of the target parameter with a predetermined operator regardless of the selection of the audio track, but it is necessary to specify the target parameter in advance on the Cubase (registered trademark) side. Therefore, every time a track or subtrack is switched, it is difficult to quickly set a target parameter in the track or subtrack.

  The present invention has been made paying attention to this point, and an electronic music system that makes it possible to easily and quickly set a target parameter in a track or sub-track each time a track or sub-track is switched. It is an object to provide a program for realizing a control method for controlling.

  In order to achieve the above object, a program according to claim 1, wherein the track of music data comprising at least one track and at least one subtrack that controls the track in time series and the subtrack are recorded. An electronic music device that displays on a display means in time series and edits and reproduces the track and the subtrack of the displayed song data, comprising a selection means for selecting the track or the subtrack And a computer control program for controlling an electronic music system comprising an editing operator and a music control device for remotely controlling the electronic music device, wherein the control method is displayed on the screen. A detecting step for detecting that a sub-track of the song data is selected, and the detecting step Therefore, in response to selection of a subtrack of the displayed song data, an assigning step of assigning the editing operator to an operator for setting a parameter assigned to the subtrack, and the editing operation And a setting step for setting a parameter assigned to the sub-track in accordance with a child operation.

  According to a second aspect of the present invention, in the program of the first aspect, the editing operator includes a presenting unit that presents a current value of a parameter to be set, and the control method further includes the selected subtrack. It has a 1st control step which controls the said presentation means so that the present value of the parameter currently allocated may be shown.

  The program according to claim 3 is the program according to claim 1, wherein the music control device further includes a selection operator for selecting the track or the sub-track, and the control method further includes the selection operator. A second control step for controlling the selection means for selecting the track or the sub-track according to an operation is provided.

  According to the first aspect of the present invention, in response to selection of a subtrack of the displayed song data, the editing operator is assigned to an operator for setting a parameter assigned to the subtrack. Since the parameters assigned to the sub-track are set according to the operation of the editing operator, the target parameter in the track or sub-track can be set easily and quickly each time the track or sub-track is switched. It becomes possible to set.

By reading it into the RAM 206, the CPU 204 can be operated in the same manner as when the control program is stored in the ROM 205. In this way, control programs can be easily added and upgraded.

  In the present embodiment, a PC on which DAW software is installed and activated is employed as the electronic music apparatus 2, but the present invention is not limited to this, and a dedicated apparatus that realizes DAW may be employed. Further, a PC on which music software that is not included in the category of DAW software is installed and activated may be used as the electronic music apparatus 2. As will be described later with reference to FIG. 2, the DAW software includes all the functions of the software sound source unit 2d, the sequencer unit 2e including a recorder (not shown), and the mixer unit 2g. It is not necessary to include DAW software that includes only a part of the DAW software. Otherwise, DAW software may be installed and started in a form that is added to the DAW software when necessary. Each function may exist as a single unit, and DAW software having only a function that controls them may be adopted. That is, it is sufficient to finally have a configuration including at least a sequencer, a sound source, and a mixer.

  FIG. 2 is a block diagram showing functional configurations of the music control device 1 and the electronic music device 2.

  The music control device 1 includes the control operator 101, the motor fader 103, and the display 107 as described above.

  The control operator 101 includes an operator 101a for designating a track, an operator 101b for designating a parameter value that can be designated regardless of the designation of the track, and a parameter that can be designated according to the designation of the track. There are four types of operators: an operator 101c for specifying a value and an operator 101d for specifying a parameter value that can be specified according to the designation of a subtrack. In the present embodiment, the motor fader 103 is for designating parameter values that can be designated according to the designation of the sub-track, like the operation element 101d. In the present embodiment, the sub-track refers to the “automation sub-track” described above in “Background Art” even if not specified.

  As described above, the display device 107 is composed of a plurality of LEDs, and most of them are embedded in the corresponding buttons (operation devices). Indicator 107b for parameters that can be specified independently of the designation of the track, indicator 107c for parameters that can be designated according to the designation of the track, and indicator 107d for parameters that can be designated according to the designation of the subtrack There is. However, in this embodiment, there is no indicator for designating a track. Of course, the present invention is not limited to this, and a display for designating a track may be provided.

  The control unit 1a mainly corresponds to the CPU 104, the ROM 105, and the RAM 106 in FIG. 1, and among the operation elements 101a to 101d and the motor fader 103, the operation state of the operation element whose operation state has changed (the knob or the motor fader 103). In this case, it is an indication position, and in the case of a button, it is on / off state) is converted into a MIDI (musical instrument digital interface) message, and then output to the electronic music apparatus 2 side according to the USB communication protocol. On the other hand, since the MIDI message is transmitted from the electronic music apparatus 2 to the music control apparatus 1 side at an arbitrary timing according to the USB communication protocol, the control unit 1a constantly monitors the MIDI message and transmits the MIDI message. When this MIDI message is received, its contents are analyzed, and the operation state of the operator (in this embodiment, the indicated position of the motor fader 103) and the display (in this embodiment, the LED is turned on / off) / Flashing) as appropriate. Although MIDI message transmission / reception is not shown in FIG. 2, the music control apparatus 1 side performs USB message transmission via the USB I / F 108 and the electronic music apparatus 2 side transmission via USB I / F 209.

  The electronic music apparatus 2 has a USB driver and a MIDI driver 2a installed. The USB driver and the MIDI driver 2a are for transmitting and receiving MIDI messages to and from the music control apparatus 1 in accordance with the USB communication protocol. Therefore, although not shown in FIG. 2, it goes without saying that the music controller 1 is also provided with a USB driver and a MIDI driver.

  The extension unit 2b is for extending the function of the application, that is, the DAW software, and is created exclusively for the music control apparatus 1. The extension unit 2b is realized by the CPU 204 executing extension software. This extension software is not normally provided in the DAW software, but is newly created to realize the present invention. Therefore, even if the DAW software is activated, the extension unit 2b is not automatically generated accordingly. For this reason, in the present embodiment, the extension software is read from the storage device 208 into the RAM 206 at the same time when starting the DAW software or when the extension unit 2b is required after starting the DAW software. Like to do.

  In this embodiment, the DAW software is mainly configured by a user interface unit 2c, a software tone generator unit 2d, a sequencer unit 2e, an effect unit 2f, and a mixer unit 2g. However, since each part 2c-2g cannot distinguish clearly each function in software, the block of each part 2c-2g is drawn with the broken line.

  The user interface unit 2c is connected to a character / numeric input keyboard (hereinafter abbreviated as “keyboard”) 201a and a mouse 201b included in the setting operator 201, and the display 207. A GUI (graphical user interface) environment of the music apparatus 2 is provided. That is, the user interface unit 2c accepts an operation input made by the user to the user interface unit 2c via the keyboard 201a and the mouse 201b, and gives an instruction corresponding to the operation input to a function that is a target of the operation input. In addition to the normal control processing to be performed, an operation input performed by the user using the control operator 101 of the music control device 1 is received via the extension unit 2b, and the operation for the function that is the target of the operation input is performed. A control process of giving an instruction according to the input is also executed. As a result, the music control apparatus 1 can remotely control various functions of the DAW software.

  The software tone generator 2d generates a digital audio signal by software. The software tone generator 2d includes a plurality of types of software tone generators (generated by a plurality of musical tone generation algorithms, manufactured by a plurality of manufacturers, etc.), and one or a plurality of tone generators are selected and used. I have to. Note that the software sound source unit 2d is composed entirely of software sound sources in the present embodiment, but is not limited to this, and may be composed entirely of hardware sound sources, so that both software sound sources and hardware sound sources can be used. May be. In the latter case, the software sound source and the hardware sound source may be distinguished and presented to the user, or may be presented together (without the user recognizing the distinction).

The sequencer unit 2e reproduces the song data stored in the song data storage area (not shown) selected by the user from the various song data stored in the storage device 208 and secured at a predetermined position in the RAM 206. To do. Each piece of music data is composed of a plurality of tracks, and a plurality of sub-tracks can be generated for each track. Examples of tracks and subtracks include the following.
(A) Audio track: A track made up of a sound waveform that forms part of a song. At the time of music reproduction, the audio waveform of the audio track is reproduced by the sequencer unit 2e and output to the mixer unit 2g as it is. On the other hand, at the time of recording, the sound waveform input from the audio signal input circuit 203 is recorded on the audio track. As sub-tracks of the audio track, volume (input attenuator at the mixer unit 2g for audio track output), mute (input mute on / off at the mixer unit 2g for audio track output), pan (for audio track output, It is possible to generate sub-tracks that define settings such as pan setting in the mixer unit 2g and send (level setting for sending the audio track output input to the mixer unit 2g from the mixer unit 2g to the effect unit 2f).
(B) MIDI track: a track composed of performance data in MIDI format that constitutes a part of a song. The performance data of the MIDI track is reproduced by the sequencer unit 2e. Then, the generated MIDI event is transmitted to an internal software MIDI module (a part of the software tone generator unit 2d) or an external MIDI device, and is used for generating musical sounds. As a subtrack of the MIDI track, a subtrack that defines parameters such as volume, mute, and pan can be generated in the same manner as the subtrack of the audio track, but the set value is used to control the MIDI sound source. Used. In addition, a MIDI-specific control change message sequence such as pitch bend may be placed in the subtrack of the MIDI track.
(C) Fx channel track: a track for controlling an effect return signal returned to the mixer unit 2g after an audio signal is sent from the mixer unit 2g to the effect unit 2f or an external effect device. As the sub track of the Fx channel track, a sub track defining the same parameters as the sub track of the audio track can be generated.
(D) Group channel track: A track for submixing a plurality of audio tracks. As a subtrack of the group channel track, a subtrack that defines the same parameters as the subtrack of the audio track can be generated.

  As described above, the sequencer unit 2e outputs the audio signal generated by reproducing the audio track of the song data to the mixer unit 2g, while the MIDI event generated by reproducing the MIDI track of the song data is generated by the software sound source unit 2d. Output to (MIDI tone generator module).

  The mixer unit 2g mixes the digital audio signal output from the software sound source unit 2d and the digital audio signal output from the sequencer unit 2e, and appropriately gives an effect to the mix signal via the effect unit 2f. And output to the CODEC 210.

  The CODEC 210 converts the digital audio signal output from the mixer unit 2g (after expansion if the digital audio signal is compressed) into an analog audio signal, and converts the analog audio signal to the sound system 211. Output to. The sound system 211 converts this analog audio signal into sound.

  The control process executed by the electronic music system configured as described above will be described first with reference to FIG. 3 and then in detail with reference to FIGS.

  FIG. 3A is a diagram illustrating an example of the configuration of the panel surface of the music control device 1. As shown in FIG. 5A, the four types of control operators 101a to 101d and a motor fader 103 are provided on the panel surface of the music control apparatus 1.

  FIG. 3B shows the sequencer displayed on the display 207 when the song data is read or newly created in the application on the DAW software and the sequencer unit 2e is ready for use. It is a figure which shows an example of the screen 207a. In the sequencer screen 207a of FIG. 5B, the volume sub-track of the audio 1 (Audio 1) track is hatched, and the volume sub-track is selected. Here, the selection of the track or sub-track is made by operating the control operator 101a (the channel select (CHANNEL SELECT) button in FIG. 3A) on the music control device 1 side, and the cursor on the electronic music device 2 side. This is done by clicking the mouse 201b in a state in which (not shown) is set to the target track or sub-track.

  A feature of the present invention is that each time a selected track or sub-track is switched, the parameter type set by the motor fader 103 is automatically switched to a type corresponding to the switched track or sub-track. Specifically, when an audio 1 track is selected, the motor fader 103 can set the value of an input attenuator (but a value that does not vary with time) with respect to the output of the audio 1 track, and the volume sub When a track is selected, the value of the input attenuator at the mixer 2g (however, the time-varying value (in FIG. 3B, time series data v)) can be set for one audio track output. When the sub-track is selected, the pan value in the mixer 2g (however, time-series data p in FIG. 3B) can be set for the audio 1-track output. It should be noted that the fader position of the motor fader 103 is automatically moved to a position for instructing a parameter value set in the track or sub-track after switching every time the selected track or sub-track is switched.

  As described above, in this embodiment, every time the selected track or sub-track is switched, the parameter type set by the motor fader 103 is automatically switched to the type corresponding to the switched track or sub-track. Therefore, it is possible to easily and quickly set a target parameter in the track or subtrack after the switching.

  Next, this control process will be described in detail.

  FIG. 4 is a flowchart showing a procedure of initialization processing executed by the electronic music apparatus 2, particularly the CPU 204. In FIG. 4, initialization processing executed by an application on the DAW software and executed by the extension unit 2b. The initialization process is shown.

  When the application is activated in response to a user activation instruction, the CPU 204 starts an initialization process and loads predetermined extension software into the RAM 206 (step S101). Here, the predetermined extension software is for generating an extension unit corresponding to the model of the music control apparatus. In this embodiment, the extension software is created for various types of music control devices and stored in advance in the storage device 208. Accordingly, in step S101, the software corresponding to the music control device 1 among the plurality of extension software in the storage device 208 is read and loaded. Of course, not all of the extension software is stored in the storage device 208, but when a part of the extension software is stored in the storage device 208 and the extension software to be loaded is not stored in the storage device 208, the extension software is stored. The software may be acquired from an external device (for example, a server) via a communication interface (not shown in the electronic music device 2 in FIG. 1, but the electronic music device 2 is normally provided).

  When the predetermined extension software is loaded in this way, the extension unit 2b is generated as shown in FIG. In response to this, the extension unit 2b also starts the initialization process. In this initialization process, first, the CPU 204 instructs the application to set a callback for a display component corresponding to the display unit 107 / drive unit 103b of the music control apparatus 1 (step S201). Here, the “display component” refers to various display components displayed on the LCD of the display 207 (for example, “m”, “s”, “R”, etc. in the sequencer screen 207a of FIG. 3B). Buttons such as “w” and parameter name display sections such as “volume” and “left and right pan”. The “display component corresponding to the display unit 107 / drive unit 103b of the music control device 1” corresponds to the display unit 107 (LED) / drive unit 103b among the various display components. However, some of the display 107 / driving unit 103b determines the corresponding display component only after the track or sub-track is determined. Therefore, in the initialization process, any track or sub-track is selected. However, for example, the track or subtrack to be selected first may be fixed, or the track or subtrack to be selected first is not determined, and the user can select the track or subtrack. Only when a subtrack is selected may the selected track or subtrack be selected. Furthermore, “callback setting” specifies a function to be called by an application among various functions prepared in the extension unit 2b when the display state of the display component corresponding to the display unit 107 / drive unit 103b changes. Is to set.

  In response to the instruction in step S201, the application performs callback setting (step S102). Next, in response to the inquiry from the extension unit 2b, the CPU 204 notifies the extension unit 2b of the state (setting value) of the display component (step S103).

  In response to this, the extension unit 2b acquires the display component state (setting value) corresponding to the display unit 107 / drive unit 103b of the music control device 1 from the application (step S202), and acquires the acquired display component state (setting). Value) is converted into a MIDI message and notified to the music control apparatus 1 (step S203).

  When receiving the MIDI message, the CPU 104 of the music control apparatus 1 analyzes the received MIDI message and reflects the analysis result on its own display unit 107 / drive unit 103b. In response to this, the state of the display 107 / drive unit 103b matches the state (set value) of the acquired display component. Note that the above-described processing on the music control device 1 side is not shown because it is not different from normal MIDI message reception processing.

  FIG. 5 is a flowchart showing the procedure of the track selection process executed by the electronic music apparatus 2, particularly the CPU 204, and shows the track selection process executed by the application and the track selection process executed by the extension unit 2 b. It is shown.

  The track selection processing on the application side is activated when any track (not including sub-tracks) is selected in the state where the sequencer screen 207a of FIG. 3B is displayed, for example. As described above, the track can be selected from either the music control device 1 side or the electronic music device 2 side. However, in the flowchart of FIG. 5, the track selection is performed from the electronic music device 2 side. The case where it went is shown. However, in the former case, that is, when the track selection is performed from the music control device 1, after performing the operation control process of FIG. 6 described later, the track selection process may be performed subsequently. When the application-side track selection process is activated, first, the CPU 204 notifies the extension unit 2b by a callback that a track has been selected (step S111). Note that when a track is selected, which of the functions prepared in the extension unit 2b is to be called is specified by the callback setting of the initialization process (see step S102 in FIG. 4). In the process of step S111, the CPU 204 passes the process to the function by a callback, that is, calls the function.

  In response to this, the extension unit 2b starts track selection processing. In this track selection process, the CPU 204 inquires the application which track is selected (step S211). In response to this, information for specifying the selected track is notified from the application to the extension unit 2b (step S112), and the extension unit 2b receives this information (step S211).

  The extension unit 2b instructs the application to update the callback setting based on the received track information (step S212). The sequencer screen 207a in FIG. 3B shows a state in which the volume sub-track of one audio track is selected as described above. From this sequencer screen 207a, the user selects one audio track, that is, its parent track. When selected, the display 107 / drive unit 103b of the music control device 1 whose display state should be changed in accordance with the selection of its parent track is turned on / off for each LED embedded in the controls 101c and 101d. / Blinking state and fader position of motor fader 103 (set value to drive unit 103b). Therefore, in this case, it is only necessary to maintain the current state of lighting / extinguishing / flashing of each LED embedded in the other operation element 101b (note that the operation element 101a has the above-described state in the present embodiment. Thus, since the LED is not embedded, there is no need to consider changing the display state of the operation element 101a. In other words, “update callback setting” in step S212 means updating the callback setting for the display component corresponding to the display unit 107 / drive unit 103b whose display state should be changed according to the selection of the track. Means.

  The subsequent processes, that is, the processes of steps S113, S114, S213, and S214, and the process executed by the music control device 1 in response to the process of step S214 are substantially the same as the corresponding processes in the initialization process of FIG. Since it is similar (if not similar, it can be easily applied by analogy), description thereof will be omitted.

The sub-track selection process when the sub-track selection is performed from the electronic music apparatus 2 side can be easily obtained by changing the track selection process of FIG. 5 as follows. That means
S111: Change “Select Track” to “Select Subtrack” S211: Change “Which track is selected” to “Which subtrack is selected and which parent track” S112: “Selected” Change "track" to "selected sub-track and its parent track" S213: change "track" to "sub-track".

  FIG. 6 is a flowchart showing a procedure of operation control processing executed by the music control device 1 and the electronic music device 2, particularly the CPU 104 and the CPU 204, when any one of the control operator 101 and the motor fader 103 is operated. FIG. 2 shows an operation control process executed by the music control apparatus 1, an operation control process executed by the extension unit 2b, and an operation control process executed by the application.

  When the motor fader 103 is operated, for example, of the control operator 101 and the motor fader 103, the CPU 104 converts the operated object, that is, the motor fader 103, and the operation amount, that is, the fader position, into a MIDI message. Then, it is transmitted to the electronic music apparatus 2 (step S321). The extension unit 2b acquires the operated target and its operation amount from this MIDI message (step S221) so that the display component corresponding to the operated target is in a state (set value) corresponding to the operation amount. The application is instructed (step S222).

  In response to this, the application sets the instructed display component to the instructed state (set value) (step S121) and executes various processes associated with the change (step S122).

  For example, in the sequencer screen 207a of FIG. 3B, the motor fader is selected with the user pressing the “w” button included in the operation element 101d and selecting the write function to the automation subtrack (volume subtrack). When the control unit 103 is operated in the upward / downward direction, the time-series data v of the volume parameter value, that is, the input attenuator value in the mixer unit 2g for the audio 1 track output is written to the selected automation subtrack. go. Here, the types of parameters are the names of parameters that can be selected when the user clicks the mouse 201b with the cursor placed on the parameter name display portion (for example, the portion where “volume” is displayed). When a name is selected from among the list in which is displayed, the parameter can be changed to that name. Therefore, the pan parameter assigned to the second subtrack (pan subtrack) can be selected also for the first subtrack (volume subtrack) of one audio track. When the pan parameter is selected for the first subtrack, the “w” button is pressed, and the motor fader 103 is moved up with the write function to the automation subtrack (volume subtrack) selected. When operated in the down / down direction, the pan parameter value, that is, the time series data p of the pan value in the mixer 2g for the audio 1 track output, is similar to the example shown in the second sub-track, The data is written on the first sub-track.

  FIG. 7 is a flowchart showing the procedure of display component state change processing executed by the electronic music apparatus 2, particularly the CPU 204. In FIG. 7, the display component state change processing executed by the application and executed by the extension unit 2 b are shown. The state change process of the display component to be performed is shown.

  In the application, first, the state (set value) of each display component is updated (step S131). As a result, among the display components whose state (set value) has changed, the callback is executed for the display component that is set to callback. (Step S132).

  In response to this, the extension unit 2b starts display component state change processing, and inquires of the application about the state (set value) of the display component (step S231). In response to this, since the application notifies the extension unit 2b of the state (setting value) of the display component (step S133), the extension unit 2b receives this information (step S231).

  The extension unit 2b converts the received state (setting value) of the display component into a MIDI message and notifies the music control device 1 (step S232). The process executed by the music control apparatus 1 in accordance with the process of step S232 is the same as the process executed by the music control apparatus 1 in accordance with the process of step S203 in FIG.

  In this way, even if the states (setting values) of various display components displayed on the LCD of the display 207 of the electronic music device 2 change, the display state of the display 107 / drive unit 103b of the music control device 1 Corresponds to the changed state (set value).

  In the present embodiment, one motor fader 103 is used as an operation element that automatically assigns a parameter of a type corresponding to the track or sub-track after the switching every time the track or sub-track is switched. The type of the operation element is not limited to the motor fader, but may be a simple fader without the driving unit 103b (in this case, the fader position does not move automatically), or may be a non-fader type operation element. . Furthermore, the number of operation elements need not be limited to one. However, as the number of operators increases, it becomes difficult to distinguish which parameter is operated by which operator, so it is necessary to clarify the correspondence between them by matching the color of the operator and the display color of the parameter. There is.

  Further, in the present embodiment, as exemplified in the sequencer screen 207a of FIG. 3B, the selected track or sub-track is indicated by a “slashed line” in order to distinguish it from other non-selected tracks or sub-tracks. However, the display mode for distinguishing between them is not limited to the diagonal line, and any display mode such as display color or reverse display may be adopted.
