  In the present embodiment, the present invention is applied to a digital mixer. However, the present invention is not limited to this, and any device that has a touch panel display and can display a plurality of user-defined keys on the display can be used. You may apply to such a thing.

  The control process executed by the digital mixer 1 configured as described above will be described first with reference to FIG. 3 and then in detail with reference to FIGS.

  Similar to the conventional digital mixer, the digital mixer 1 displays a plurality of user-defined keys on the LCD 3a, and executes functions assigned to the user-defined keys in response to user touch operations on the user-defined keys. Is configured to do. However, in the conventional digital mixer, the display mode of the user-defined key is almost common across all the user-defined keys, whereas in the digital mixer 1, as shown in FIG. User-defined keys are grouped according to the condition that functions are assigned, the display mode is shared for each key group, and the display mode of user-defined keys in each key group is displayed in the shared display mode. The point is different.

  FIG. 3 is a diagram showing a screen of the LCD 3a when user-defined keys are grouped and displayed with a common user-defined key display mode for each key group. FIG. 4A shows an example in which the key background is shared for each key group, and FIG. 4B shows an example in which the shape of the user-defined key is shared for each key group. ) Shows an example in which the description (caption) of the function and parameter assigned to the key is displayed in the vicinity of each key in addition to the display mode of FIG. Shows an example in which the display position of the parameter description is changed with respect to the display example of FIG. Note that one function description is displayed for each key group, and one parameter description is displayed for each key.

  In addition, since it cannot be colored in the drawing, it is drawn in monochrome. However, in addition to the display modes of FIGS. 3A to 3D, if the display color of the key is changed for each key group. The visibility of the user with respect to the result of sharing the key display mode for each key group is further improved.

  3A to 3D, which display mode is used for display may be freely selected by the user, or may be fixedly determined in advance. In this embodiment, it is assumed that the user can freely select.

  Thus, in this embodiment, user-defined keys are grouped according to the condition that adjacent and related functions are assigned, and the display mode of user-defined keys is shared for each key group. It is possible to intuitively grasp at a glance which adjacent keys and the functions related to which keys are assigned.

  Next, this control process will be described in detail.

  FIG. 8 is a diagram showing the format of various tables used in this control process. (A) shows a function-category table (Function-Category Table), (b) shows a category table (Category Table), and (c) shows a key layout table (Category Table). (D) shows a key group table, and FIG. 4D shows a key group table.

  The function-category table is a table indicating to which category a function that can be assigned to a user-defined key belongs. The function-category table is preset in a factory setting or the like and stored in the ROM 9, for example. Here, some of the assignable functions will be briefly described. “Scene No” indicates the number assigned to each scene memory (not shown), “Fader 001” indicates the 001th fader among a plurality of faders, and “Mute Group 001” The 001th mute group in the case where all output channels are divided into a plurality of groups to form a mute group that can be muted at once is shown. “Category” is a superordinate concept of “function”. In this embodiment, “category” is used to generate a “key group”. In the present embodiment, the function-category table cannot be freely changed by the user. However, the function-category table is not limited thereto, and may be freely changed.

  The category table defines the display mode of user-defined keys for each key group (corresponding to the above category). For each category, the shape of the background (Back Ground), the key shape (Key Shape), and the category It defines the presence or absence of a caption (Caption-Category) and the presence or absence of a parameter caption (Caption-Param). The category table is created in a predetermined area of the RAM 10 or the external storage device 11. Here, “Goggle-Shaped” set as the shape of the background is the shape 3a1 in FIG. 3A, and “Rounded-Rectangle” is the shape 3a3 in FIG. 3A. “Ellipse” refers to the shape 3a2 in FIG. “Ellipse” set as the key shape refers to the shapes 3a1 and 3a3 in FIG. 3B, and “Connected” refers to the shape 3a2 in FIG. 3B. Further, the category caption is a description of “category” displayed on the user-defined key in FIGS. 3C and 3D, and when “On” is set, ), (D), and when “Off” is set, no caption is displayed as shown in FIGS. 3 (a) and 3 (b). The parameter caption is a description of the “parameter” displayed under or on the user-defined key in FIGS. 3C and 3D. When “On” is set, the caption display is displayed. If “Off” is set, no caption display is performed. In this embodiment, the category table is set so that the user selects and sets the value of each item for each category. However, the category table is not limited to this, and is set in advance in the same manner as the function-category table. The default function-category table is used when the user does not want the function-category table selection setting, and the default is used when the user desires the function-category table selection setting. The function-category table may be editable.

  The key layout table defines which user-defined key is adjacent in which direction for each user-defined key. Since the key layout table is uniquely determined when the number and arrangement of user-defined keys displayed on the LCD 3a are determined, the key layout table is set in advance and stored in the ROM 9 in the same manner as the function-category table. It should be noted that the key layout table does not need to be changed by the user, and therefore may not be edited.

  The key group table is used to register a key group including user-defined keys that are adjacent and to which related functions are assigned, and is created in a predetermined area of the RAM 10 or the external storage device 11. The key group table is created by the CPU 7 based on the function-category table and the key layout table.

  FIG. 4 is a flowchart showing a procedure of key group table creation processing executed by the digital mixer 1, particularly the CPU 7.

  The key group table creation process is a process for creating a key group table based on the function-category table and the key layout table as described above. Before describing the key group / table creation process in detail based on the flowchart, an outline of the algorithm of this process will be described.

  First, (1) one of the user-defined keys is set as a target key, and (2) one of the user-defined keys adjacent to the target key is set as an adjacent target by referring to the key layout table. Set to key. Next, (3) key group creation / addition processing is performed based on the function assigned to the adjacent target key. Then, while moving the adjacent target key, the process (3) is performed on all the user-defined keys adjacent to the target key. Further, the above processes (2) and (3) are performed on all user-defined keys while moving the target key.

  Returning to FIG. 4, the key group / table creation process is started when the user-defined key is displayed on the LCD 3a or when the function assigned to the user-defined key is changed.

  In this key group / table creation process, first, the CPU 7 sets the first one (for example, the smallest key number) of the user-defined keys as a target key (step S1). Next, if a function is assigned to the target key, the CPU 7 acquires the function information (steps S 2 → S 3 → S 4). Here, the function information is, for example, a name of a function assigned to each user-defined key on the setting screen (see FIG. 9B) described in the conventional digital mixer. Then, the CPU 7 performs adjacent key analysis processing based on the acquired function information and the target key (step S5).

  In the present embodiment, whether or not a function is assigned to a user-defined key can be freely determined by the user, so there may be a user-defined key to which no function is assigned. For user-defined keys to which no function is assigned, registration to the key group table is not performed. Therefore, if a user-defined key to which no function is assigned is set as the target key, the target The adjacent key analysis process is not performed for the key (steps S3 → S6).

  The processes in steps S3 to S5 are performed for all user-defined keys while moving the target key one by one (step S6 → S2 → S3 to S5 →... → S2 → end).

  FIG. 5 is a flowchart showing a detailed procedure of the adjacent key analysis process in step S5.

  In this adjacent key analysis process, first, the CPU 7 acquires the key numbers of all user-defined keys adjacent to the target key (step S11), and sets one of the user-defined keys as the adjacent target key. (Step S12). Of the processes in subsequent steps S13 to S17, the processes excluding the key group creation / addition process in step S16 can be immediately inferred from the processes in steps S2 to S4 and S6 in FIG. .

  FIG. 6 is a flowchart showing a detailed procedure of the key group creation / addition process in step S16.

In this key group creation / addition process, the CPU 7 mainly executes the following process. That is,
(11) When a key group corresponding to the category to which the function assigned to the adjacent target key belongs (category described in the function-category table) has not yet been generated, the key group is newly generated, The key number of the adjacent target key is registered in the generated key group (steps S21 → S22 → S23).
(12) When a key group corresponding to the category to which the function assigned to the adjacent target key belongs has already been generated,
(12a) When a user-defined key adjacent to the adjacent target key is included in the key group, the key number of the adjacent target key is registered in the key group (steps S21 → S24 → S25).
(12b) If the key group does not include a user-defined key that is adjacent to the adjacent target key, the category is the same as the key group generated in the process of (11) above. A different key group is generated, and the key number of the adjacent target key is registered in the generated key group (steps S21 → S24 → S22 → S23).

  Note that the reason why the processing of (12b) is provided is that, for example, two key groups of the same category may exist apart (not adjacent), and in this case, both key groups are the same. This is because even the category must have separate key groups.

  In this way, a key group table as shown in FIG. 8D is created.

  FIG. 7 is a flowchart showing the procedure of the user-defined key display process. In this user-defined key display process, the user-defined key is displayed for the first time after the function assigned to the user-defined key is changed (at this time, the key group / table creation process is executed at least once). Then it is executed.

In the user-defined key display process, the CPU 7 mainly executes the following process. That is,
(21) For each key group, the user-defined keys belonging to the key group are drawn in the designated display mode (steps S33 to S35).
(22) User-defined keys not included in the key group are individually drawn (steps S36 → S37).

  Before executing the process (21), the CPU 7 acquires information necessary for drawing (step S31). Specifically, the information necessary for the drawing is described in the display of the user-defined key in any of the display modes in FIGS. 3A to 3D and the category table. Information.

  The reason why the process (22) is provided is that some user-defined keys may not include a key group. What does not constitute a key group is specifically a user-defined key to which no function is assigned, or a user-defined key to which a function that is not related to any of the adjacent user-defined keys is assigned. It is.

  In this way, when the user-defined key display process is executed, the user-defined key is displayed in any one of the designated display modes in FIGS. 3 (a) to 3 (d).
