JP-A-8-83075

  In conventional electronic musical instruments, when editing the waveform data assignment state or deleting the assigned waveform data, the user needs to select the waveform data. When assigned to a key or a key range, it is extremely difficult to select target waveform data.

  The keyboard of an electronic musical instrument has a large number of keys, for example, 61 keys. For example, when different waveform data is assigned to each key, such as a drum tone, the waveform data options are also selected. Since there are only the number of keys, it is not easy to find the target waveform data.

  In addition, there is a disadvantage that it is difficult to intuitively understand the relationship between the displayed option and the key when assigning waveform data to the key or key range. For example, regarding a waveform assigned to the key range “C2-C3”, even if “C2-C3” is displayed as an option, some users may not immediately know which key it is. is there.

  In view of such circumstances, it is an object of the present invention to provide an electronic musical instrument that can easily select waveform data assigned to each key or key range of a keyboard.

  According to one feature of the present invention, a keyboard (14) composed of a plurality of keys (C1 to C6) and a screen for displaying a waveform assignment screen (We) showing an assignment state (Aw) of waveform data to the keyboard (14) Display means (16; S0), operation means (DRw; S0) capable of mode setting operation corresponding to display of waveform assignment screen (We), and waveform selection mode according to operation of operation means (DRw) Mode setting means (S4) for setting the value, transpose setting means ([0051]) for setting the transpose value [eg, +12 (= 1 octave up)], and the key of the keyboard (14) in the waveform selection mode In response to an operation (for example, C3 key depression), a transpose (for example, one octave) from the operated key (for example, C3) by a value set by the transpose setting means. Waveform data assigned to the assigned key (for example, C4) is selected as an assignment edit target (Se1), and the waveform selection means (S10, [0051] that enables the assignment state of the selected waveform data to be edited. ] An electronic musical instrument (computer) comprising: a keyboard (14) comprising a plurality of keys (C1 to C6) and operating means (DRw), and a computer functioning as an electronic musical instrument. A screen display step (S0) for displaying a waveform assignment screen (We) showing the waveform data assignment state (Aw) to the keyboard (14), and an operating means (DRw) corresponding to the display of the waveform assignment screen (We) Enabling step (S0) for enabling mode setting operation, and mode setting step for setting the waveform selection mode in accordance with the operation of the operating means (DRw) S4), a transpose setting step ([0051]) for setting a transpose value [for example, +12 (= 1 octave up)], and a key operation (for example, C3 key pressing) on the keyboard (14) in the waveform selection mode. ), Waveform data assigned to the key (for example, C4) transposed (for example, one octave up) from the operated key (for example, C3) by the value set in the transpose setting step. Provided is a waveform assignment program (Claim 3) for executing a procedure comprising a waveform selection step (S10, [0051]) that is selected as an assignment edit target (Se1) and that enables the assignment state of the selected waveform data to be edited. Is done. Note that the parentheses indicate the corresponding reference symbols of the embodiments added for the sake of understanding.

  In the electronic musical instrument according to the present invention, the assignment state (Aw) displayed by the display means (17; We; S0) is waveform name information indicating waveform data and a key range indicating a key range to which the waveform data is assigned. It can be configured to include information.

  The electronic musical instrument (computer) according to the present invention displays the waveform data assignment state (Aw) when editing the assignment of the waveform data to the keyboard composed of one or more keys of the keyboard (14). Corresponding to the display of the data allocation state (Aw), the mode setting operation by the operation means (DRw) becomes possible (S0). In addition, a transpose value can be set ([0051]). Here, when the waveform selection mode is set according to the user operation of the operation means (DRw) (S4) and a transpose value [for example, +12 (= 1 octave up)] is set, this waveform selection is performed. When a key operation (for example, C3 key depression) of the keyboard (14) is performed in the mode, a key (for example, one octave up) that is transposed by a value set from the operation key (for example, C3) (for example, The waveform data assigned to C4) is selected (Se1), and the assignment state of the selected waveform data can be edited (S10, [0051]).

  That is, according to the present invention, when any key on the keyboard is operated in the waveform selection mode, the waveform data assigned to the key transposed by the set value from the operation key is selected. Therefore, it is possible to easily select the target waveform data assigned to each key of the keyboard in consideration of the set transpose value as the target of assignment editing. In addition, it is possible to easily select the waveform assigned to the keyboard, and to edit the waveform data in the selected state such as changing the assigned state or deleting it from the assignment target. .

[Overview of waveform assignment]
In the electronic musical instrument according to one embodiment of the present invention, the waveform data is assigned to a key range composed of one or more keys of the keyboard. FIG. 2 shows an example of waveform data allocation in an electronic musical instrument according to an embodiment of the present invention. Symbols C1, C # 1, D1,... Attached to the keys exemplify the pitches of the keys. In the illustrated example, the keyboard 14 of the electronic musical instrument is a “C1” key to 61 keys up to “C6” key are provided.

  “Assignment example 1” shown in FIG. 2A shows an example of assignment of waveform data such as musical notes, and “waveform A” for each predetermined key range C1 to B1, C2 to B2,..., C5 to C6. , “Waveform B”,..., “Waveform D” are assigned predetermined waveform data specified by the name (waveform name information). In this example, each key range is approximately in octave units, but may be smaller or larger than one octave, and the pitch ranges of the key ranges may not be equal to each other.

  “Assignment example 2” shown in FIG. 2 (b) shows an example of assignment of waveform data such as drum sounds. For each key C1, C # 1, D1, D # 1, E1,..., B5, C6, Predetermined waveform identified by the names (waveform name information) “waveform 1”, “waveform 2”, “waveform 3”, “waveform 4”, “waveform 5”,. Data is allocated.

  FIG. 3 shows an example of a waveform editing screen We displayed on the display 16 when editing to assign waveform data to each key or key range of the keyboard 14 and an example of function assignment of the corresponding switch in the setting operator 15. Show. This waveform editing screen We is a display example at the time of “drum sound waveform editing” in which waveform data is assigned to each key as shown in FIG. 2B, and each key C1 to C6 has already been displayed in FIG. It is assumed that “Waveform 1” to “Waveform 61” are already assigned as shown in FIG.

  On the waveform editing screen We, a keyboard figure (image) Kb for displaying the keyboard 14 of the electronic musical instrument is displayed at the top, and along the right side of the screen, an additional operation guide image Ad indicating addition of the waveform, and deletion of the waveform are displayed. A deletion operation guide image Dt and a storage operation guide image Sv indicating storage of the setting state are displayed. Further, a waveform attribute information display area At is provided below the keyboard display image Kb, and a waveform assignment guide area Aw, a start key guide area Ks, and an end key guide area Ke are provided along the lower side of the screen.

  The waveform assignment guide area Aw includes an upper waveform assignment display section and a lower waveform selection guide section. The waveform assignment display section has waveform name information for designating waveform data and a key set for the waveform data. Waveform assignment information including area information is displayed, and the currently selected waveform data is highlighted. For example, the waveform allocation information “waveform 1: C1 to C1” at the top of the figure indicates that the waveform data indicated by the waveform name information “waveform 1” is assigned to the key “C1”, and the symbol “Se1”. As indicated by “”, it is highlighted by bold / italic fonts or shaded to indicate that “waveform 1” is currently selected. The waveform data includes not only data representing the waveform itself based on sampling or the like, but also a waveform parameter set in which calculation parameters for generating a desired waveform are combined.

  In the waveform assignment display section, displayable waveform assignment information including the currently selected waveform is displayed. In this display example, “Waveform 1” to “Waveform 4” including “Waveform 1” being selected are displayed. "Is assigned to each of the keys" C1 "to" D # 1 "is displayed on the waveform assignment display section. In this example, a predetermined waveform is assigned to each of 57 keys “E1” to “C6” that cannot be completely displayed on the waveform assignment display section. The allocation contents of the waveform allocation information of all the key ranges are called “allocation map”.

  The key to which the currently selected waveform is assigned is also highlighted (emphasized) on the keyboard figure Kb. For example, when “Waveform 1: C1 to C1” is selected as in this display example, the key C1 in the keyboard figure Kb is highlighted as indicated by the symbol “Se2”. Further, the waveform attribute information display area At is displayed as necessary, and various attribute information relating to the currently selected waveform data, for example, a specific name (nickname) of the waveform data, a sample rate, a length, etc. Is displayed.

  This waveform assignment state can be selected by a selective operation of a predetermined switch corresponding to the guidance display of the operation guidance unit. That is, in the operation guidance section of the waveform assignment guidance area Aw, a direct guidance image indicated by “direct”, “up (Δ)”, and “down (▽)” and an up and down guidance image are displayed. The image corresponds to the switch on which the up / down operation indications “Δ” and “▽” are made adjacent to the lower side of the display 16. These switches are assigned functions as waveform selection buttons when the waveform editing screen We is displayed on the display 16.

  More specifically, the function of the “waveform direct button DRw” is assigned to each of the two Δ / ▽ switches (the left end in the drawing) at a position corresponding to the direct guide image (“direct”). In addition, each of the three Δ switches (second step from the bottom in the figure and second to fourth from the left end) corresponding to the up guide image “up (Δ)” has a function of “waveform up button UPw”. Is assigned, and the function of the “waveform down button DNw” is assigned to each of the three ▽ switches (2nd to 4th from the left end in the lowermost figure in the figure) at the position corresponding to the down guide image “down (▽)”. It is done.

  For example, every time the user operates the waveform up or down buttons UPw and DNw, the waveform assignment information is scrolled and highlighted one by one upward or downward, so that the desired waveform assignment information is highlighted (Se1). When the operation of the buttons UPw and DNw is stopped when it is done, the target waveform data can be searched. When the user presses the waveform direct button DRw, the waveform selection mode is set. In this waveform setting mode, when a key desired to be selected in the keyboard 14 of the electronic musical instrument is pressed (for example, while pressing the button DRw), waveform allocation information relating to the waveform allocated to the pressed key is immediately displayed in the waveform allocation display section. Is highlighted (Se1), and the target waveform data can be searched.

  The start key and end key guide areas Ks and Ke are each composed of an upper start key and end key display section and a lower start key and end key selection guide section. Start key (lowest pitch key: key at the left end of the key range to which the waveform is assigned) and end key (highest pitch key: key at the right end of the key range to which the waveform is assigned) of the range to which the waveform is assigned Display start key and end key information is displayed. In this display example, since predetermined waveform data is assigned to each key and the key range is composed of one key, the lowest and highest pitch keys in the key range are equal, and the current “waveform 1” is Is selected. Accordingly, “C1” is displayed on the start key display portion and the end key display portion as shown in the figure.

  These start key and end key can be selected by selectively operating a predetermined switch corresponding to the guidance display of the start key and end key selection guide section. For example, for the start key selection guide section in the start key guide area Ks, a direct guide image indicated by “direct”, “up (△)”, and “down (▽)” and an up and down guide image are displayed. These images correspond to the switches with “Δ” and “▽” of the up / down operation adjacent to the lower side of the display 16. These Δ / ▽ switches are assigned a function as a button for selecting a start key in a key range relating to the currently selected waveform data.

  That is, the function of the “start key direct button DRs” is assigned to each of the two Δ / ▽ switches (fourth from the right end in the drawing) corresponding to the direct guide image “direct”. In addition, the function of the “start key up button UPs” is assigned to the Δ switch (second step from the bottom in the figure and third from the right end) corresponding to the up guide image “UP (Δ)”, and the down guide image “DOWN ( The function of the “start key down button DNs” is assigned to the ▽ switch (third from the right end in the lowermost stage in the drawing) at the position corresponding to “▽”.

  Therefore, every time the user operates the start key up or down button UPs, DNs, the start key is scrolled up or down one by one and displayed on the start key display section, so that the desired start key is displayed. If the button UPs or DNs operation is stopped when the button is pressed, the target start key can be determined. When the user presses the start key direct button DRs, the start key selection mode is set. In this start key selection mode, when a key to be selected on the keyboard 14 is pressed (for example, while pressing the button DRs), the pressed key can be immediately selected and determined as a target start key.

  In order to select the end key of the key range related to the currently selected waveform data, similarly for the end key selection guide section in the end key guide area Ks, two Δ / ▽ switches corresponding to the direct guide image “direct” The function of the “end key direct button DRe” is assigned to (second from the right end in the figure), and “END” is assigned to the Δ switch (the rightmost end in the second row from the bottom in the figure) corresponding to the up guide image “UP (Δ)”. The function of the “key up button UPe” is assigned, and the function of the “end key down button DNe” is assigned to the ▽ switch (at the rightmost end in the figure) at the position corresponding to the down guide image “down (）)”.

  Therefore, every time the user operates the end key up or down button UPe, DNe, the end key is scrolled up or down one by one and displayed on the end key display section, so that the desired end key is displayed. When the button UPe, DNe operation is stopped when the key is pressed, the target start key can be determined. Further, when the user presses the end key direct button DRe, the end key selection mode is set. In this end key selection mode, when the user presses a key to be selected on the keyboard 14 of the electronic musical instrument (for example, while pressing the button DRe), Immediately, the pressed key can be selected and determined as the end key of the selected waveform key range.

  For the operation of the waveform, start key or end key direct buttons DRw, DRs, DRe, the selection mode is set by turning on the button, and the original non-selection mode is switched by turning off the button. The For example, when the buttons DRw, DRs, and DRe are turned on, the waveform selection mode, the start key selection mode, or the end key selection mode is set, respectively, until the off operation is performed (that is, while the button is kept pressed). Depending on the key operation, waveform selection, start key selection or end key selection corresponding to the operation key is performed. Further, the original state can be restored by turning off the buttons DRw, DRs, and DRe. Each time the button is operated, the selection mode may be switched to the original non-selection mode.

  The user can add and delete waveform data and save the waveform data setting state using the waveform editing screen We. Therefore, the additional operation guidance image Ad, the deletion operation guidance image Dt, and the storage operation guidance image Sv are displayed corresponding to the three switches “A” to “C” adjacent to the right side of the screen. In these switches “A” to “C”, when the waveform editing screen We is displayed on the display 16, an “add button BA” for instructing addition of waveform data, and deletion of waveform data, respectively. A “delete button BB” for instructing and a function as a “save button BC” for instructing to save the waveform data setting state obtained using the waveform editing screen We are assigned.

  Here, the outline of the waveform assignment function of the electronic musical instrument will be described with reference to FIG. In this electronic musical instrument, during the waveform assignment process, the waveform editing screen We is displayed on the display 16, and the assignment state of the waveform data to the keyboard 14 is displayed on the waveform assignment display area in the waveform assignment guide area Aw. The Δ / ▽ operation switch (lower left in the figure) corresponding to the waveform assignment guide area Aw functions as a waveform direct switch DRw that enables setting of the waveform mode. When the user operates the waveform direct switch DRw, the waveform selection mode is set accordingly. Further, when a key operation on the keyboard 14 is performed in this waveform selection mode, the highlighted waveform Se1 is displayed on the waveform assignment state corresponding to the waveform data assigned to the operation key, and the waveform data is selected. To the user. In addition, for the selected waveform data, the allocation state can be edited on the waveform editing screen We.

[Waveform assignment process flow]
In one embodiment of the present invention, waveform data assigned to a key range consisting of one or more keys of a keyboard can be easily selected according to a waveform assignment program. FIG. 4 is a flowchart showing an example of a waveform assignment process executed in the electronic musical instrument according to the embodiment of the present invention.

  First, when this processing flow is started (step S0), the CPU 1 first displays the waveform editing screen We, and switches around the screen We, as shown in FIG. 3, include waveform direct, up and down buttons DRw, It functions as UPw, DNw, start and end key direct, up and down buttons DRs / DRe, UPs / UPe, DNs / DNe, add / delete / save buttons BAS, BB, BC.

  Here, if there is a user operation of the add button BA, an add button process is executed in step S1, and if there is no such operation, this step is passed. In the add button processing, a “waveform addition screen” (not shown) is displayed on the display 16 in accordance with the operation of the add button BA, the waveform data to be added is designated in accordance with the waveform designation operation, and the key range corresponding to the waveform data is designated. The start key is set according to the user operation. In addition, the end key of the key range may be set by the user in the same manner, or may be automatically set according to a predetermined rule. Then, by the addition determination operation by the user, the designation of the waveform data is added to the voice (timbre) data, the setting state of the additionally designated waveform data is included in the waveform assignment information, and the waveform editing screen We is returned.

  If there is a user operation of the delete button BB, delete button processing is executed in the next step S2, and if there is no such operation, this step is passed. In the delete button process, in response to the operation of the delete button BB, the waveform editing screen We highlights the waveform assignment display area in the waveform assignment guide area Aw and designates the currently selected waveform data as voice (timbre) data. The setting state of the waveform data whose designation is deleted is excluded from the waveform assignment information.

  If there is a user operation of the save button BC, the save button process is executed in the next step S3, and if there is no such operation, this step is passed. In the save button process, the current waveform data assignment setting state on the waveform editing screen We is saved as voice (tone color) data in accordance with the operation of the save button BC. For example, if the assignment of the drum sound waveform has been edited, it is stored as voice data related to the drum tone color, and if the assignment of the first piano sound waveform is edited, it is stored as voice data related to the first piano sound color. To do.

  If there is a user operation of the waveform direct button DRw, the waveform direct button process is executed in the next step S4, and if there is no such operation, this step is passed. In the waveform direct button process, when the waveform direct button DRw is turned on, the keyboard 14 is set to the waveform selection mode. Further, when the operation is turned off, the original state (normal state) is restored.

  If there is a user operation (ON operation) of the waveform up button UPw or the waveform down button DNw, the waveform up / down button process is executed in the next step S5, and if there is no such operation, this step is passed. In the waveform up / down button processing, the waveform data in the selected state is changed up or down by one according to the operation of the waveform up button UPw or the waveform down button DNw. In this case, when the waveform data is not displayed on the waveform assignment display section in the waveform assignment guide area Aw, the display on the waveform assignment display section is scrolled. Further, the range of the start key to the end key of the selected waveform data is displayed together with the waveform assignment display unit in the form of figures, characters or numbers.

  If there is a user operation of the start key direct button DRs, start key direct button processing is executed in the next step S6, and if there is no such operation, this step is passed. In the start key direct button process, when the start key direct button DRs is turned on, the keyboard 14 is set to the start key selection mode. Further, when the operation is turned off, the original state (normal state) is restored.

  User operation of the start key up button UPs or the start key down button DNs (if there is an on operation, start key up / down button processing is executed in the next step S7, and if there is no such operation, this step is passed. In the key up / down button processing, the start key information of the waveform assignment information is corrected by changing the currently set start key up or down for the currently selected waveform data, and the start key guide area Ks. The start key display of the start key display part of the waveform assignment guide area Aw is updated, and the range display of the start key to the end key displayed in the waveform assignment display part of the waveform assignment guide area Aw is updated. Overlapping the set start key to end key range It not possible. In addition, the pitch of the start key with respect to the waveform sound high is limited such that less sound end key height.

  If there is a user operation of the end key direct button DRe, end key direct button processing is executed in the next step S8, and if there is no such operation, this step is passed. In the end key direct button process, when the end key direct button DRe is turned on, the keyboard 14 is set to the start key selection mode. Further, when the operation is turned off, the original state (normal state) is restored.

  The user operation of the end key up button UPe or the end key down button DNe (if there is an on operation, end key up / down button processing is executed in the next step S8, and if there is no such operation, this step is passed. In the key up / down button processing, with respect to the currently selected waveform data, the currently set end key is changed one up or down to correct the end key information of the waveform assignment information, and the end key guidance area Ke The end key display of the end key display section is updated, and further, the range display of the start key to the end key displayed in the waveform assignment display section of the waveform assignment guide area Aw is updated, except for other waveform data. Duplicate settings cannot be made within the range of the set start key to end key. And, pitch the end key respect the waveform sound high is limited such that the pitch or the start key.

  If there is a user operation on the keyboard 14, keyboard processing is executed in the next step S10, and if there is no such operation, this step is passed. In the keyboard process, in a normal state, a musical sound based on the waveform data assigned to the key operated by the ON operation is generated, and the assigned state of the waveform data can be confirmed with the musical sound. Also, the musical sound is muted by the off operation. Further, in another state, that is, in the waveform selection mode, the start key selection mode or the end key selection mode, the following operation is performed.

  That is, in the waveform selection mode, the waveform data assigned to the operated key is selected by referring to the assignment map, and the range of the start key to end key is assigned to the waveform data selected by the ON operation. It is displayed on the edit screen We. In this case, if no waveform is assigned to the key, nothing happens. In the start key or end key selection mode, the selected key is set as the start key or end key for the waveform data currently selected by the ON operation, and the start key in the waveform assignment display section of the waveform assignment guide area Aw is set. ~ Update end key range display. However, as described above, it cannot be set in the range of the start key to the end key already set for other waveform data, and the pitch value of the start key ≦ the end key pitch value with respect to the waveform. The pitch value is limited.

  In the next step S11, it is determined whether or not an “EXIT” button (not shown) has been operated. While the “EXIT” button has not been operated (S11 → NO), the process returns to step S1 and responds to the various operations described above. The corresponding steps S1 to S10 are repeated. End determination: When an “EXIT” button (not shown) is operated (S11 → YES), the waveform assignment process is ended. When the setting state is not saved at the end of the process, the user may be inquired about whether or not the setting state should be saved.

  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, in the case of direct selection based on the operation of the direct buttons (DRw, DRs, DRe), the set transpose value may be taken into consideration. For example, when +12 (= 1 octave up) is set as the transpose value, if the operated key is C3, it is read as C4 and the waveform is selected or the start key or end key is selected. To do.

  The processing that can be performed on the waveform data selected by direct selection (DRw + arbitrary key) may be other than assignment map setting (start key and end key setting) and deletion. For example, the waveform data itself Editing (name editing, sample rate editing, length editing, processing with a filter, etc.) or other processing may be used.

  Further, the operator for setting the waveform selection mode is not limited to the switch around the display to which the direct button function is assigned, and a dedicated switch may be provided on the panel of the electronic musical instrument.
