Description

  The present invention relates to an electronic musical instrument and a program.

  2. Description of the Related Art Conventionally, in electronic musical instruments such as an electronic piano and a keyboard, a function called “dual or layer” for overlapping a plurality of timbres is known. When the layer function is turned on, the tone of the main part tone and the layer part tone are played simultaneously.

  There is also known a function called split, which divides the key range into left and right and plays different tones on the left and right. In the split function, a fixed position is set as a split point, a pitch higher than the split point is set as a right part (right key range), and a lower pitch is set as a left part (left key range). When the split function is turned on, when the right part is played, a tone is generated according to the tone of the right part, and when the left part is played, a tone is generated according to the tone of the left part.

  Furthermore, in an electronic musical instrument having both a layer function and a split function, for example, when the layer function is turned on for a light part when the split function is turned on and the light part is played, the main part is played. It is possible to play the tone of the part tone and the layer part tone at the same time.

  In such an electronic musical instrument, the on / off state of each part (main, layer, left part, etc.), the tone set for each part, etc. are displayed on the display panel or LED installed on the main panel of the electronic musical instrument body. Thus, various setting states can be confirmed without playing (without actually sounding) (see, for example, Non-Patent Document 1).

“Clavinova CVP-509 / 505/503/501 Instruction Manual”, [online], 2009, Yamaha Corporation, [searched on December 7, 2011], Internet <URL: http: //www2.yamaha. co.jp/manual/pdf/emi/japan/cla/cvp509_ja_om_d0.pdf>

  In an electronic musical instrument, settings may be changed during the performance or the settings may be confirmed, and it is desired that the current setting state can be intuitively confirmed.

  However, in the conventional electronic musical instrument, since the setting states of each part and the like are displayed as a list, each piece of information becomes small and may be difficult to see. Regardless of whether each part is on or off, the information on all parts is always displayed on the display screen, so it may be difficult to instantly determine which tone will sound with the current settings. is there. In addition, since there is no relationship between the display position on the display screen and the actual sound generation position (key range), it is possible to intuitively understand which tone is played by which keyboard (range) from the display on the display. Difficult to do.

  An object of the present invention is to make it easy to recognize a setting state in an electronic musical instrument.

  According to one aspect of the present invention, an electronic musical instrument includes a musical sound generating unit that generates musical sounds by a plurality of pronunciation parts, each of which is assigned a timbre and a range of sounds that are generated using the timbre, and information on the pronunciation parts. Display means having a display area to be displayed, switching means for switching between a sounding state and a mute state for each of the plurality of sounding parts, and the display area according to the sounding part brought into a sounding state by the switching means In the first mode in which the first sounding part and the second sounding part are simultaneously sounded, the dividing means for dividing the first sounding part and the second sounding part correspond to the first sounding part and the second sounding part. In addition to the first sound part and / or the second sound part, a third sound part is arranged so that the second sub display area is adjacent in the vertical direction. However, in the second mode in which sound is generated in a range different from that of the first and second sound parts, a third sub display area corresponding to the third sound part, and the first and / or second sub display areas Are divided so as to be adjacent to each other in the left-right direction, and display control means for displaying information on the sounding part in the sounding state in the divided display area.

  According to the present invention, it is possible to provide an electronic musical instrument whose setting state is easy to recognize.

As a result, the user can easily recognize that only the tone color of the main part is produced in the entire key range.

  FIG. 4B is an example of screen division when the main part and the layer part are on (sounding state) and the left part is off (silenced state).

  Since the main part and the layer part are on and the left part is off, the main part on / off button 44 and the layer part on / off button 45 are displayed in a display mode (solid line) indicating the on state, and the left part on / off button 46 represents the off state. Displayed in a display mode (broken line).

  Since the left part is off (split mode off), the screen is not divided into left and right parts, but only up and down. A main area 41 is arranged in the upper area of the timbre name display section 40 divided vertically, and a layer area 42 is arranged in the lower area. For example, the upper and lower division boundary lines are set so that the high volume part area is enlarged and the low volume part area is displayed small based on the volume balance between the main part and the layer part.

  Further, since the left and right division is not performed, the left key range display portion 48L is not displayed on the tone generation key range display portion 48, and the right key range display portion 48R is displayed in the entire area. As a result, the user can easily recognize that the timbres of the main part and the layer part are simultaneously generated in the entire key range. In addition, since the position of the upper and lower boundary lines is set according to the volume balance, the volume balance between the main part and the layer part can be easily confirmed.

  FIG. 4C is an example of screen division when the main part and the left part are on (sounding state) and the layer part is off (silenced state).

  Since the main part and the left part are on and the layer part is off, the main part on / off button 44 and the left part on / off button 46 are displayed in a display mode (solid line) indicating the on state, and the layer part on / off button 45 represents the off state. Displayed in a display mode (broken line).

  Since the layer part is off, the screen is not divided into upper and lower parts, but only the left and right parts are divided. A main area 41 is arranged in the right area of the timbre name display section 40 divided into left and right, and a left area 43 is arranged in the left area. The boundary line of the left and right division is set based on the split point, as will be described later.

Correspondingly, the left and right division positions of the timbre name display section 40 are also set to have the same width as that of the left area display section 48L.

  FIG. 4D shows an example of screen division when the layer part and the left part are on (sounding state) and the main part is off (silenced state).

  Since the layer part and the left part are on and the main part is off, the layer part on / off button 45 and the left part on / off button 46 are displayed in a display mode (solid line) indicating the on state, and the main part on / off button 44 represents the off state. Displayed in a display mode (broken line).

  Since the main part is off, the screen is not divided into upper and lower parts, and only the left and right parts are divided. A layer area 42 is arranged in the right area of the timbre name display section 40 divided into left and right, and a left area 43 is arranged in the left area. The boundary line for the left and right division is set based on the split point, as in the example shown in FIG.

  When only the layer part is on, the layer area 42 is displayed on the entire surface of the timbre name display unit 40, as in the state where only the main part shown in FIG.

  Also, since the left part is always sounded only in the left key range, even when only the left part is on, it is displayed on the left side of the screen in accordance with the split point, and the initial state shown in Fig. 2 (all parts are on) Or the main part and the left part shown in FIG. 4C are displayed in the same division mode as in the on state. At this time, the main part 41 (and the layer part 42) is displayed such as “No Voice” indicating that the sound is muted.

  As described above, by dividing the screen, the user can visually recognize the parts that are currently turned on, and also visually recognize the relationship between the parts (whether they are pronounced at the same time or divided into left and right). It becomes possible.

  In this embodiment, when the left part is on, as shown in FIGS. 5A and 5B, the left and right division positions of the timbre name display unit 40 are determined in accordance with the split point (in conjunction with the position). Is done. That is, the left part sounded in the left key range is displayed on the left side of the screen, and the parts (main part and layer part) sounded in the right key range are displayed on the right side of the screen.

  For example, as shown in FIG. 5A, when a split point is set near the center of the key range, the left / right division position of the timbre name display unit 40 is the same as the position where the split point is set. Set near the center of the key range.

  As shown in FIG. 5B, when a split point is set near the left end of the key range, the left and right division positions of the timbre name display section 40 are the same as the positions where the split points are set. Set near the left edge of the key range.

  As described above, in this embodiment, since the left and right division positions of the timbre name display section 40 are determined in conjunction with the split point setting position, the display width in the left and right direction of the display area of each part in the timbre name display section 40 is determined. From this, it is possible to know the approximate key range.

  Note that if the left and right division positions of the timbre name display unit 40 are determined in full linkage with the split point setting position, the left area 43 becomes too narrow depending on the split point setting position, and necessary information is displayed. It may be impossible to do this. Therefore, when the width of the left area 43 is equal to or smaller than a certain value, the split point and the left / right split position of the screen are stopped, and the split point and the left / right split position of the screen are changed as shown in FIG. It may be displayed in a shifted manner.

If it is within the pronunciation key range display section 48, the process proceeds to step SB4 indicated by the arrow “C”, and after the pronunciation key range setting screen is displayed on the display 14 (FIG. 1), the process proceeds to step SB11 and the tone color setting process is performed. And the process proceeds to step SA9 in FIG.

  In step SB5, the display mode of the part on / off button (main part on / off button 44, layer part on / off button 45, left part on / off button 46) that detected the operation is changed from the on state to the off state or from the off state to the on state.

  In step SB6, the timbre part corresponding to the detected part on / off button (main part on / off button 44, layer part on / off button 45, left part on / off button 46) is switched on / off (sound / silence).

  In step SB7, the timbre name display section division control processing shown in FIG. 8 is executed, and the display of the timbre name display section 40 is divided according to the on / off (sounding / silence) state of each timbre part. Thereafter, the process proceeds to step SB8. In step SB8, it is determined whether or not the operation determined in step SB2 is an operation of the left part on / off button 46. If it is an operation of the left part on / off button 46, the process proceeds to step SB9 indicated by a YES arrow. Otherwise, the process proceeds to step SB11 indicated by a NO arrow, and the timbre setting process is terminated. Proceed to step SA9 in FIG.

  In step SB9, according to the operation of the left part on / off button 46, the sound key range of the main part and / or the layer part is changed. When the left part on / off button 46 is changed from on to off (when the split mode is changed from on to off), the sound key range of the main / layer part is changed from “right key range” to “all key range”. The On the other hand, when the left part on / off button 46 is changed from OFF to ON (when the split mode is changed from OFF to ON), the sound key range of the main / layer part is changed from “all key range” to “right key range”. Be changed.

  In step SB10, the display of the sounding key range display section 48 is changed in accordance with the change of the sounding key range in step SB9. For example, when the left part is turned on, the left key range display portion 48L is displayed from the left end of the set tone key range display portion 48 to the split point. For example, when the left part is turned off, the left key range display portion 48L is not displayed. Thereafter, the process proceeds to step SB11, the tone color setting process is terminated, and the process proceeds to step SA9 in FIG.

  FIG. 8 is a flowchart showing the timbre name display section division control process executed in step SB7 of FIG.

  In step SC1, the timbre name display section division control process is started. In step SC2, it is determined whether or not the left part is currently on (sounding state). If the left part is on, the process proceeds to step SC3 indicated by a YES arrow. If the left part is off, the process proceeds to step SC5 indicated by an arrow of NO, the entire timbre name display unit 40 is set as the main / layer area, and the process proceeds to step SC6.

  In step SC3, as described with reference to FIG. 5, the timbre name display unit 40 is divided into left and right regions in accordance with the set split points. In the dividing process, for example, when 30% of the entire key range is set as the left key range, the left 30% region of the timbre name display unit 40 is set as the left region 43. As described above, when the left area 43 has a certain width (minimum required width) and necessary information cannot be displayed, the left area 43 may be divided with the minimum required width regardless of the split point. good.

  In step SC4, the right area is set as the main / layer area among the left and right areas divided in step SC3, and the left area is set as the left area 43. Thereafter, the process proceeds to Step SC6.

  In step SC6, it is determined whether or not one or both of the main part and the layer part are currently on (sounding state). If both the main part and the layer part are on, the process proceeds to step SC7 indicated by a YES arrow. If only one of the main part and the layer part is on, or if both parts are off, the process proceeds to step SC8 indicated by a NO arrow.

  In step SC7, the vertical division position of the main / layer area, which is the right area of the timbre name display section 40, is determined according to the volume balance (ratio) between the main part and the layer part. Arranged above, the layer area 42 is arranged below and divided vertically. When the main area 41 or the layer area 42 has a certain height (minimum required height) and necessary information cannot be displayed, the main area 41 or the layer area 42 is divided into upper and lower parts at the minimum required height regardless of the volume balance. Also good.

  In step SC8, the timbre image and text of the timbre part that is on are displayed in accordance with the position and size of each area. At this time, when only the left part is on (when the process proceeds from step SC6 to step SC8 according to the arrow of NO), the right main / layer area has a timbre in the right area such as “No Voice”. Display that part is off. Thereafter, the process proceeds to step SC9, the timbre name display section division control process is terminated, and the process proceeds to step SB8 in FIG.

  As described above, according to the embodiment of the present invention, by dividing the display screen of the timbre part, the user can easily visually recognize the part that is currently turned on, and the relationship between the parts (whether they are pronounced at the same time, Etc.) can be easily visually recognized.

  In addition, the display size of the timbre display area 30 is not changed when the display areas of the accompaniment style display area 31 and the song display area 32 are enlarged. Therefore, the information in the timbre display area 30 depends on the state of the home screen. When the home screen is displayed, it is possible to always check the setting state of each timbre part in the same state.

  In the above-described embodiment, when the timbre name display unit 40 is divided into upper and lower parts, the main area 41 is arranged on the upper side and the layer area 42 is arranged on the lower side. However, depending on the octave or transpose setting of each part, The higher one may be displayed above and the lower one may be displayed below.

  Further, the upper and lower division positions of the timbre name display unit 40 may be displayed in such a manner that the higher one is wider and the lower one is narrower according to the octave or transpose setting of each part, not the volume balance.

  In addition, when the timbre name display unit 40 is divided into upper and lower parts, the upper and lower dividing lines may be fixed and the sizes of the main area 41 and the layer area 42 may be fixed regardless of the volume balance or the like. In this case, the volume balance may be expressed by enlarging or reducing the display size of the timbre image (icon) or the like displayed in each area in proportion to the volume. Also, in that case, the volume balance of the left part with respect to the main part and layer part is also expressed by scaling the display size of the timbre image (icon) etc. in proportion to the volume, and the volume balance of all the parts is visually recognized. You may be able to do it.

  Further, in the above-described embodiment, a plurality of timbre parts can be set only in the right area in the split mode, but a main part and a layer part can also be set in the left area so that four timbre parts can be set. You may do it. In this case, the left area is also divided and displayed according to the above-described vertical division method of the right area.

  Further, in the split mode, it is not limited to the left and right division, and may be divided into three or more areas. Furthermore, in the layer mode, not only the two timbres of the main and layer can be pronounced simultaneously, but three or more timbres may be pronounced simultaneously. In these cases, depending on the number of timbre parts, Divide the screen horizontally and vertically.
