An electronic musical instrument (computer) comprising a display means (S3) for displaying the displayed parameters in a graphic form on the planar display (16), and a plurality (n) of keys (C1 to C6). ) And a keyboard (13) formed in the vicinity of the keyboard (13) i) Arranged in a matrix so that the direction coincides with the key arrangement direction (K) of the keyboard (13) and the direction of the column (j) coincides with the direction orthogonal to the key arrangement direction (K) of the keyboard (13). Related to a keyboard (13) in a computer (electronic musical instrument) comprising a plurality of (mn) display elements (Dij: 1 ≦ i ≦ m, 1 ≦ j ≦ n) and a planar display (16) A parameter setting step (S2) for setting parameters (key range parameters) to be performed, and a display step (S3) for displaying the parameters set in the parameter setting step (S2) on the planar display (16) as graphic figures A parameter setting display program (Claim 3) for executing the procedure is provided. Note that the parentheses indicate the corresponding reference symbols, terms, and the like of the embodiments added for convenience of understanding.

  In the electronic musical instrument according to the present invention, the display means (S2) is represented by the graphic figure in the empty display area (for example, i = 10 to 12) where the graphic figure is not displayed on the planar display (13). Information relating to the parameters to be displayed can be displayed as characters and / or numbers (for example, FIG. 3 [a]) [Claim 2].

  In the electronic musical instrument according to the present invention, a planar display (16) in which a plurality of (mn) display elements (Dij: 1 ≦ i ≦ m, 1 ≦ j ≦ n) configured by LED elements or the like are arranged in a matrix. Is arranged in the vicinity of the keyboard (13). Regarding the display element arrangement in the planar display (16), the row (i) direction matches the key arrangement direction (K) of the keyboard (13), and the column (j) direction corresponds to the key arrangement direction of the keyboard (13) ( K) and the display element (Dij) corresponds to the entire key range (C1) of the keyboard (13) so that each row is aligned with each key (C1 to C6) of the keyboard (13). To C6: Number of keys = n). When various key range parameters related to the key range of the keyboard (13) such as key range division parameters and key scaling parameters are set (S2), the set key range parameters are graphically displayed on the surface display (16). A graphic is displayed (S3).

  Therefore, according to the present invention, on the surface display provided over the entire keyboard in the vicinity of the keyboard, various keyboard parameters set in relation to the keyboard are displayed as graphic figures, and the keyboard parameters are displayed. Since the amount of display information is made to correspond directly to the keyboard, it is easy to grasp the correspondence between the key range parameters and the keyboard, and the key range parameters can be displayed in an easy-to-understand manner. In addition, the user can easily check the set key range parameters, and when setting a new key range parameter, the parameter setting range specified by the keyboard operation is displayed in a planar manner near the keyboard. Key range parameters can be created or edited while checking with a device.

  Further, in the electronic musical instrument according to the present invention, setting information relating to various key range parameters can be displayed in a table intent form such as letters and numbers in an empty display area other than the graphic figure display part (for example, 3 (a)), it becomes easier to understand the contents of various key range parameters currently set in relation to the keyboard.

[System Overview]

Are connected to each other.

  The CPU 1 executes various music information processing including parameter setting display processing using a clock by a timer according to a predetermined control program. The RAM 2 is used as a work area for temporarily storing various data necessary for these processes. In addition, in order to execute these processes, the ROM 3 stores various control programs including a parameter setting display program, preset various key range parameters, performance data, and the like.

  The “key range parameter” means a parameter that can be set in relation to the key range (including one key) of the tone control parameters used for generating the tone signal. There are a “key range division parameter” that assigns a predetermined tone color to each key range and a “key scaling parameter” that represents a key scaling state of musical tone control parameters such as touch curve, filter, volume, and tuning.

  The external storage device 4 is not only a built-in storage medium such as a hard disk (HD) but also a compact disk read only memory (CD-ROM), a flexible disk (FD), a magneto-optical (MO) disk, a digital multipurpose disk ( Various data can be stored in an arbitrary external storage device 4 including various portable external recording media such as a small memory card such as a DVD and a smart media (registered trademark).

(Configuration of area indicator and key range parameter setting display)
In an electronic musical instrument according to an embodiment of the present invention, in order to display various key range parameters set corresponding to the key range of the keyboard, a planar shape configured by arranging a large number of LED display elements in a planar shape. A display is provided in the vicinity of the keyboard, and various parameters can be set in association with the keyboard according to the parameter setting display program, and the set various parameters can be graphically displayed on the surface display. FIG. 2 is a flowchart showing an example of parameter setting display processing according to one embodiment of the present invention, and FIG. 3 shows a planar display and a display example in an electronic musical instrument according to one embodiment of the present invention.

  Parameters used for generating musical tone signals in an electronic musical instrument include key range parameters that are set according to the key range (including one key) of the keyboard 13. For example, the key division parameter is used to divide the keyboard 13 into two or more key ranges and assign parameters such as timbre to each key range. In addition, various parameters such as touch curve, filter, volume, and tuning may be set uniformly for all keys on the keyboard 13 regardless of the key range, but are set so that the rate and level change depending on the key range. In many cases, a rich musical expression is made. Changing the parameter value depending on the key range in this way is called key scaling, and these parameters set by key scaling are called key scaling parameters. In this electronic musical instrument, it is possible to display such key range parameters in an easy-to-understand manner by using a planar display device arranged close to the keyboard.

  First, a configuration example of the planar display 16 will be described with reference to FIG. The planar display 16 is arranged on the front panel in the vicinity of the keyboard 13, and is formed by arranging a large number of display elements D11, D12,. A planar display body including n columns of display elements Dij (1 ≦ i ≦ m, 1 ≦ j ≦ n) is formed. Each display element Dij that functions as a display element of the planar display body is configured by, for example, an LED element. In FIG. 3, the off state (light-off state) is indicated by a white pattern, and the on-state (lighting state). This is shown in black.

  The surface display 16 is provided with LED display elements Dij in a matrix over the entire key range of the keyboard 13. The row positions j of the display elements Dij are arranged corresponding to the keys of the keyboard 13, and in this example, n LED elements equal to the total number n of keys of the keyboard 13 are provided along the key arrangement direction K. It is done. The row positions i of the display elements Dij are arranged in a direction orthogonal to the key arrangement direction K of the keyboard 13, and m LED elements are provided for each key in the key arrangement orthogonal direction. In the illustrated example, the keyboard 13 of the electronic musical instrument has 61 keys “C1” to “C6”, and the number of columns of display elements is n = 61. In addition, 12 LEDs are provided for each key, and the number of display element rows m = 12.

  Parameter display example 1 in FIG. 3A shows a display example when displaying the key range division parameters for the keyboard 13. In this case, the state of the key range division is displayed graphically as a stepped figure using the lower three stages [i = 10 to 12 (= m)] of the LED display elements Dij of the surface display 16. . For example, when the keyboard 13 is set to be divided into two upper and lower key ranges, the corresponding key is set to the lower key range by turning on (lighting) the lowermost LED [i = 12 (= m)]. It is shown that the corresponding key is set in the upper key range by turning on (lighting) the LED [i = 10] in the third row from the bottom.

  In the illustrated example, the keyboard 13 is divided into two upper and lower key ranges with the “C3” key as a dividing point (split point: the lowest pitch key of the high pitch side key range), and the lowest step [i = 12 (= m) ], By turning on the LED display elements Dij of j = 1 to 24, the user is informed that the lower key range has been set for the corresponding “C1” to “B2” keys, and three steps from the bottom. The upper key range is set to the corresponding “C3” to “C6” key by turning on the LED display elements Dij of j = 25 to 61 (= n) among the LEDs [i = 10] of the eyes. To the user.

  When the keyboard 13 is set to be divided into upper, middle, and lower three key ranges, the lower key range and the third lowermost LED are turned on as in the case of two divisions. Each of the upper key ranges is displayed, and it can be indicated that the corresponding key is set to the middle key range by turning on (lighting) the LED [i = 11] in the second row from the bottom.

  When the key range division parameters are displayed as shown in FIG. 3A, the upper eight LEDs [i = 1 to 8] are used to display each key range at an upper position corresponding to each step graphic. Information indicating the tone color designated for each key range can be displayed in a table intent such as letters and numbers. In the illustrated example, since the bass tone color and the piano tone color are set in the lower key range and the upper key range, the setting states are displayed as “BASS” and “PIANO” in alphabet. In this case, the LED display element D9j [j = 1 to 61 (= n)] in the fourth stage from the bottom [i = 9] is not used for display and is set to “always off”. Can be clearly separated from the graphic display of the key range by the lower three-stage LEDs [i = 10 to 12].

  In this way, when the state of the key range division is displayed in a stepped graphic figure by a plurality of steps (three rows) of LEDs, the lower key range LED is also lit in the lower stage, and the middle key range to the upper key range For the LED, the LED above it (the second and third steps from the bottom) lights up, and the image of the LED row that displays each key range according to the upper key range, middle key range to upper key range corresponds Therefore, the amount of information is abundant as compared with the prior art in which the key range is displayed with a single-stage LED, and it is easy to understand the state of each key range. Further, since the LEDs are arranged over the entire key range of the keyboard 13, the letters and numbers representing the parameter functions designated for each key range can be displayed in a large and easily understandable manner.

  Note that the divided key ranges are not limited to those assigned with a normal keyboard performance tone as described above, and other parameter functions may be assigned. For example, an automatic accompaniment chord designation function can be assigned to the divided key range. In this case, the fact that the chord designation function is assigned may be displayed with letters or numbers, or when there are a plurality of chord designation modes, which mode is displayed. Alternatively, the arpeggio performance function can be assigned to the divided key range, and in that case, the fact that the arpeggio performance function is assigned may be displayed with letters or numbers, and the arpeggio performance mode and pattern type When there are a plurality of patterns, the mode or pattern may be displayed.

  As a method for designating a region division point (key split point), a key (for example, “C3” in the example shown in the figure) while pressing a predetermined region division designation switch (for example, lower key range division designation switch). A method of operating a key can be used. In this case, when dividing into three areas, the lower key area division designation switch and the middle key area division designation switch may be operated in the same manner.

  As another division point designation method, a method of designating the division position by operating the "+" or "-" switch or dial as a key position designation means while pressing the division designation switch is adopted. May be. Alternatively, instead of pressing the division designation switch as described above and performing another operation, the division designation switch is used as a division designation mode designation means, and after operating this to enter the division designation mode, keys, switches, etc. The division position designation operation may be performed according to the above, and the division designation mode may be held until a separately provided EXIT switch is operated. Further, the dividing point may be designated by a method other than these.

  Parameter display example 2 in FIG. 3B shows a display example when key scaling parameters are displayed. In this case, all the LED display elements Dij [i = 1 to 12 (= m), j = 1 to 62 (= n)] of the planar display 16 are used to generate a touch curve used for generating a musical sound signal. The key scaling state for various parameters such as filter, volume, and tuning can be divided into 12 levels and represented graphically. The illustrated example shows the key scaling state of the parameter representing the filter characteristics, and the state in which the cutoff frequency of the low-pass filter changes according to the key range is represented by a line graph.

  As a key scaling state designation method, a method in which a user operates a key whose parameter value is to be changed while pressing a predetermined scaling designation switch. For example, if an arbitrary key is operated while pressing the “+” designation switch, the scaling value corresponding to the key increases, and if an arbitrary key is operated while the “−” designation switch is pressed, the scaling value corresponding to the key is increased. To be reduced. In this case, the two keyboard positions specified by the key operation are taken as break points (break points) of the scaling curve, and two break points having the scaling value set by the operation of the “+” or “−” specification switch are arbitrary. By performing an operation of connecting with a straight line or a curve, a scaling value designating operation for each key can be omitted, and a scaling curve in which both break points are connected with a straight line or a curve can be obtained. Further, the scaling state may be set by another method.

  When the key scaling parameter is displayed as a broken line graphic figure as shown in FIG. 3B, the graphic figure is displayed in the empty display area where the graphic figure is not displayed on the planar display 16 as necessary. Information relating to the parameters being displayed may be displayed as a table intent such as letters or numbers (for example, “filter” or its abbreviation “FL” in FIG. 3B).

  Here, the characteristics of the electronic musical instrument according to the embodiment of the present invention can be summarized as follows. In this electronic musical instrument, a plurality of display elements Dij (1 ≦ i ≦ m, 1 ≦ j ≦ n) composed of LED elements or the like are arranged in the vicinity of the keyboard 13 in the entire key range C1 to C6 (the number of keys). A planar display 16 arranged in a matrix is provided over n). The row (i) direction of the matrix arrangement coincides with the key arrangement direction K of the keyboard 13, the column (j) direction coincides with the direction orthogonal to the key arrangement direction K, and the display element Dij of each column (j) Are aligned with the keys C1 to C6 of the keyboard 13. When various key range parameters related to the key range of the keyboard 13 such as the key range division parameter [a] and the key scaling parameter [b] are set, the set key range parameters are displayed on the surface display 16 as a graphic figure. Is displayed. In addition, in the empty display area other than the graphic figure display portion, information on the key range parameter can also be displayed in a table intention form such as characters and / or numbers. For example, in FIG. 3A, the upper and lower key ranges based on the key range division parameters are displayed in the lower three rows [i = 10 to 12], and the timbres “bass” and “piano” assigned to the upper and lower key ranges are set. Is displayed in the display area of the top eight lines [i = 1 to 8].

  Next, the parameter setting display procedure will be briefly described with reference to the processing flow shown in FIG. First, when the user operates the parameter setting switch in the setting operator 14, the parameter setting mode of step S1 is entered, and the CPU 1 displays the names of various key range parameters that can be set according to the key range in the parameters on the display 15. Display a list on the setting screen. On the other hand, when a user operation for designating the name of the desired key range parameter is performed, the process proceeds to step S2, and the key range parameter designated by the designated name is read from the ROM 3 or the external storage device 4 onto the RAM 2, Set the relevant key range parameters.

  In the parameter setting in step S2, information (referred to as parameter information) explaining the content and function of the read key range parameter may be displayed on the parameter setting screen to allow the user to confirm the parameter. The key range parameter may be edited. The editing of the key range parameter includes correction (change) of parameter information and correction (change) of the content of the key range parameter.

  In addition, when the content of the key range parameter is corrected, the content of the key range parameter can be corrected / changed according to the user operation by the method described above. For example, with respect to the key range division parameter, the user performs the operation of designating the tone color to be assigned to each key range, and then operates the division designation switch and operates the key as the division point, thereby dividing the key range. Points can be corrected. As for the key scaling parameter, the key scaling state can be corrected by operating the key while operating the scaling designation switch “+” or “−”.

  In the parameter display stage of the next step S3, the contents of the key range parameters that are currently set are displayed on the surface display 16. For example, when only confirming parameters or editing only parameter information, the contents of the read key range parameters are displayed as they are in graphics, letters and numbers. When editing the parameter contents, the contents of the key range parameter currently being edited are displayed in the same figure.

  For example, when editing the contents of the key range division parameter, since the key range division of the keyboard 13 is designated using the operated key as the division point, as shown in FIG. The staircase graphic corresponding to this key range division is displayed graphically by the lower three-stage [i = 1-10-11] LEDs, and each key area of the staircase graphic is displayed by the upper eight-stage [i = 1-8] LEDs. The tone specified in is displayed with letters and numbers. When editing the contents of the key scaling parameter, a scaling value corresponding to the operation amount of the scaling designation switch “+” or “−” is designated for the operated key. As described above, the LED corresponding to the set scaling value is turned on among the LEDs of the surface display 16 and the scaling parameter is displayed as a graphic figure.

  In the subsequent step S4, it is detected whether or not the OK switch has been operated. If the user's desired setting has not been made and the OK switch has not been operated (S4 → NO), the process returns to the parameter setting stage in step S2 and is designated. The parameter setting (editing) and display processing in steps S2 and S3 are repeated for the key range parameters.

  In this way, the user confirms that the desired setting has been made for the key range parameter from the display contents of the display 15 and the planar display 16 in steps S2 and S3, and OK if the user understands this. When the switch is operated (S4 → YES), necessary post-processing is performed on the key range parameter. For example, when only the key range parameters are displayed (no editing), the key range parameters are set in the musical tone signal generation units 8 and 9 as necessary. When a new key range parameter is created by editing the parameter, the new key range parameter after editing is saved in the external storage device 4 as necessary, or the key range parameter is generated as a musical tone signal. Set in parts 8 and 9. Then, after performing necessary post-processing, the process proceeds to step S5.

  In step S5, it is detected whether or not the setting completion switch has been operated. When there is a next key range parameter that the user wants to set and the setting completion switch is not operated (S5 → NO), the process proceeds to step S6. In step S6, the next parameter is designated in accordance with the user operation, and then the process returns to step S2 to repeat the parameter setting, display and approval determination processes in steps S2 to S4 for the next key range parameter, and Necessary post-processing is performed every time (S4 → YES).

  Then, the user confirms the setting contents of all the key range parameters to be set, and after passing through necessary post-processing, when the setting completion switch is operated (S5 → YES), the parameter setting display processing is ended.

[Various Embodiments]
The preferred embodiment of the present invention has been described above with reference to the drawings. However, this is merely an example, and the present invention can be variously modified without departing from the spirit of the invention. For example, regarding the structure of the planar display, display elements may be arranged in a range (j> n) exceeding the entire key range of the keyboard. Furthermore, a display area including this range (j> n) may be an empty display area for displaying letters and numbers.

  The display contents of the surface display can be shared not only for the key range parameter but also for other displays. For example, a performance guide is displayed in the performance guide mode, and the parameter is displayed when a parameter not related to the keyboard is set.

  Further, the types of the key range parameters displayed on the surface display are not limited to those exemplified in the embodiment, and include arbitrary parameters set according to the key range. In addition, a graph-like figure that graphically represents a parameter and a table intent form such as letters and numbers may be displayed in different display modes such as color, brightness, and continuous lighting / flashing.

  Furthermore, in addition to the planar display (16), the same content as the planar display may be reduced or displayed on the LCD or the like (15) on the operation panel. Alternatively, the planar display may be configured by an LED element having a switch function, an LCD with a touch panel, or the like, and the parameter value may be set according to a designation operation on the planar display. When a planar display is configured with an LCD, each display element may be a collection of a plurality of small pixels or a single large pixel, and does not necessarily match the pixel. In addition, it is practical to configure a planar display with a plurality of LCD panels.

  Further, the planar display is not limited to m = 12, n = number of keys (61), and m may be more or less than 12 (however, at least in order to enable graphic display) 2 or more), n may be larger than the number of keys. For example, by providing two or more columns of display elements for each key, it is possible to increase the display resolution of the table intent shape such as key range parameter figures and letters / numbers, and the display becomes easier to see. Moreover, you may comprise with displays other than LED and LCD.
