Description

  The present invention relates to an electronic musical instrument capable of performing various settings in a musical instrument main body using a performance operator (pitch designation operator) such as a keyboard.

  2. Description of the Related Art Conventionally, some electronic musical instruments perform functions different from the original pitch designation using performance operators such as a keyboard and performance information representing pitches. For example, in the automatic accompaniment device for an electronic musical instrument disclosed in Patent Document 1, it is possible to perform the following melody performance by playing a pre-registered performance pattern on the upper keyboard without operating the fill-in switch on the panel surface. The accompaniment pattern is automatically changed from the normal pattern to the fill-in pattern for only the bar.

  Further, in the electronic musical instrument of Patent Document 2, note events of a specific channel among MIDI channels (16 channels) that can be received as performance information are assigned to event codes, and the specific channel of the specific channel is received from an external device (MIDI keyboard). When a note event is received, a function corresponding to the event code assigned to the received note event is executed. For example, 1 is START / STOP, 2 is REGIST +, 3 is REGIST-, and the like. Performance information for control is transmitted from an externally connected MIDI keyboard. Further, the performance data processing device (PC) of Patent Document 3 also detects special combinations of MIDI events (performance data) that cannot be a normal performance when performance information is transmitted from the external performance device (EM). A predetermined function corresponding to this combination in advance is executed.

[Example of key pressing function in key pressing alternative mode]
In the electronic musical instrument according to the embodiment of the present invention, the environment of the electronic musical instrument can be set by operating the keyboard (5K) without operating the setting operator of the input operation unit 5 in the key pressing alternative mode. it can. In other words, in the key pressing alternative mode, the pitch information of the predetermined pitch change generated based on the predetermined operation of the keyboard (5K) according to the key pressing alternative rule (RL) determines the environment setting and setting mode of the electronic musical instrument. Used to do. FIG. 2 is a diagram for explaining an example of a key depression alternative rule according to one embodiment of the present invention.

  In the key pressing alternative mode, a pitch change pattern represented by pitch information based on a series of key pressing operations is called a “key pressing pattern”. In the ROM 3 or the predetermined external storage device 4, a key pressing pattern table PT indicating a correspondence relationship between the key pressing pattern and the setting item (environment setting item) regarding the environment of the electronic musical instrument is stored in advance together with the key pressing alternative rule RL. Thus, the user can specify a desired setting item by inputting a predetermined key pressing pattern. FIG. 2 (1) shows an example of correspondence between environment setting items and key pressing patterns based on the key pressing pattern table PT. In this example, the tempo setting can be specified by the key pressing pattern: C3 → D3 → E3, and the tone color setting can be specified by the key pressing pattern: C3 → G3 → E3. Further, the music selection can be designated by the key depression pattern: F3 → A3 → C4, and the page jump can be designated by the key depression pattern: G2 → B2 → D3. Further, ON / OFF switching of the metronome can be designated by a key pressing pattern: G3 → G3 → C4. It should be noted that the function to be associated with the key press pattern may be all or some setting functions related to the environment of the electronic musical instrument.

  For the setting items specified based on the key pressing pattern, the first type for executing the setting of the specified item as it is, such as “Metronome ON / OFF”, “Tempo setting”, “Tone setting” , Such as “Volume setting”, a second type that shifts to a state where the corresponding control parameter value is changed and accepted (referred to as “setting standby state”), and “Song selection”, “Page jump”, etc. As described above, the third type that displays the corresponding screen and shifts to a state (called “selection waiting state”) in which a display element (“screen element” or simply “element”) can be selected from the screen is selected. is there. In other words, for the setting item of the first type, when this setting item is designated, it can be instructed to set to the setting state opposite to the current setting state.

  On the other hand, in the case of the second and third types, since it is necessary to further determine the value, the control parameter is controlled by operating the keyboard (5K), not by operating the setting operator, as in the item setting. Is set to a desired value or a desired display element is selected from the screen. For this reason, in the key pressing alternative rule RL, not only the setting items are specified according to the key pressing pattern table PT, but also how the control parameter value is set according to the predetermined key pressing pitch and the screen element is set. The function in the process of setting the control parameter value corresponding to the key pressing operation and selecting the screen element is specified. In the key press substitution rule RL, in principle, functions related to setting contents such as a key press pattern are performed by white key operation, and functions related to setting procedures such as confirmation and cancellation are performed by black key operation.

  In other words, when specifying setting function items such as control parameter value setting and screen element selection, as described above, a desired item must be specified by playing a white key phrase corresponding to a predetermined key pressing pattern. Can do. Further, when a control parameter value is specifically set or a screen element is selected, a white key having a desired pitch may be operated. In this case, when setting a control parameter value such as a tempo value or a volume value, the key depression pitch immediately after entering the setting standby state corresponds to the control parameter value (default value or current value) before the change, and thereafter If the key depression target key (white key) is moved to the high tone side, the value is increased by a value corresponding to the movement amount from the immediately following key depression tone pitch, and if it is moved to the low tone side, the value is decreased by a value corresponding to the movement amount. For example, when the key is F3 → G3 → A3 when the default value 120 is in the tempo setting waiting state, the reference position (pitch) is determined when the F3 key is pressed, and 121 and A3 are pressed when the G3 key is pressed. It changes to 122 with the key. If the key is pressed in the order of F3 → C4 → G4 instead of F3 → G3 → A3, the reference position (pitch) is determined when the F3 key is pressed, and changes to 124 when the C4 key is pressed and 128 when the G4 key is pressed. In addition, when selecting a screen element, the screen displayed immediately after the selection standby state is, in principle, the element of the value corresponding to the reference pitch E4 is selected by default, and an arbitrary key (white key) is selected. When the key is pressed, an element separated by a value corresponding to the pitch distance (number of white keys) from the reference pitch E4 to the key pressing pitch is selected (described later in FIG. 3).

  On the other hand, the black key is mainly used to make an OK judgment on the result obtained by the white key operation. Basically, when the black key is operated, the state immediately before that is determined. There are also special uses for white and black keys. FIG. 2 (2) shows an example of a special key pressing rule in which a function on the setting / selection process is associated with a special key pressing pitch change (special key pressing operation) in the key pressing alternative rule RL.

  In FIG. 2 (2), the uppermost function: “continue key press input” is, for example, when the maximum sound of the keyboard (5K) comes when the value is gradually raised while pressing the key. In order to continue to increase the value, the key to be pressed is moved to the left (bass) side of the keyboard so that the increase in the value can be resumed. If you press one white key that is more than two octaves away in the opposite direction, you can continue to press the key. Further, after a plurality of white key operations, the functions of the “confirm” and “cancel” buttons on the normal user interface screen can be executed by a special key pressing operation. That is, as shown in the second row, when one black key within one octave before and after the previous key press (white key input) is pressed, the control parameters or elements set or selected by the key press operation until the previous key press The value of Also, as shown at the bottom, if you press one black key that is more than one octave away from the previous key press (white key input) (that is, a black key that is in a range exceeding one octave), the settings up to the previous key are set. Or the selection contents are discarded, and the original state before the setting or selection operation is restored.

  FIG. 3 shows an example of the setting screen 6S displayed when the setting item of the third type is designated together with the keyboard 5K. In the ROM 3 or the storage device 4 of this electronic musical instrument, automatic performance data called “song” is prepared, and in the key pressing alternative mode, the music selection is designated by the key pressing pattern: F3 → A3 → C4. As shown in FIG. 3 (1), the display unit 6 displays a music selection screen 6S in which song names: Song1, Song2,... Are ordered in the right direction and arranged in parallel over several stages using a number of prepared automatic performance data as selection elements. Can be displayed on the display. The state shown in the drawing shows a state in which “Song1” is selected and highlighted by default, and the default selection state for selecting the element: “Song1” is the sound of the keyboard 5K shown in FIG. It corresponds to the high E4 white key. That is, in this example, the pitch E4 becomes the reference pitch for element selection on a selection screen for selecting a desired element from a plurality of elements on the screen as in the music selection screen 6S.

  Therefore, for example, when the white key E4 is pressed on the music selection screen 6S of FIG. 3A, the selection state in which “Song1” is selected does not change. Next, as indicated by the solid line arrow, when the white key F4 adjacent in the right direction is pressed, “Song2” on the right side in the screen 6S is selected and highlighted. When the white keys G4 and A4 are sequentially pressed, “Song3” and “Song4” are selected. In addition, even if the white key E4 is pressed in the default state, the selection state in which “Song1” is selected does not change. Next, if one is placed and the white key G4 is pressed, 1 is displayed on the screen 6S. The third automatic performance data that has been placed and ordered: “Song3” is selected. Furthermore, if one is placed and the white key B4 is pressed, the fifth automatic performance data: “Song5” is selected.

  In the key press alternative mode, by specifying the page jump music selection by the key press pattern: G2-> B2-> D3, as shown in FIG. , Page 2,... Can be displayed on the display. In this example, there are five pages of page data, and page tabs each representing the name of each page are arranged in the right order. The state shown in the figure shows a state in which “page 2” is selected by default and the contents of page 2 are displayed. The default selection state in which the element: “page 2” is selected corresponds to the reference pitch E4 of the keyboard 5K. ing.

  Here, for example, when the white key E4 is pressed on the page selection screen 6S of FIG. 3 (2), the selection state in which “page 2” is selected does not change, and next, a solid line arrow As shown, when the white key F4 adjacent to the right is pressed, the next “page 3” having a page tab on the right in the screen 6S is selected, and the contents of page 3 instead of page 2 are selected. Is displayed. Next, when one key is skipped and the white key A4 is pressed, “page 5” after two pages is selected. However, when the white key D5 (not shown) is pressed, “page 1” is selected. That is, since the designated page data has only 5 pages, when “page 5” is selected, when a higher pitch (D5) is first depressed, the corresponding key depression pitch (D4) is selected. ) To select “page 1” becomes a new criterion. Note that the white key pitch may be repeatedly associated with the page without using a new reference. For example, after selecting “Page 5” by pressing the white key A4, pressing the adjacent white key B4 may shift the selection state to “Page 1”. Further, in the state shown in the drawing, as indicated by the broken line arrow, when the white key D4 in the left direction is pressed, “page 1” is selected.

  The confirm button DF and the cancel button CA that are displayed in the lower right of each screen so as to be operable have the same function as the buttons on the normal user interface screen, and the cursor can be “confirmed” or “ You can confirm or cancel the selection by pressing the Enter key or double-clicking according to the notation of “Cancel”, but you can easily do the same by simply operating the black key as shown in Fig. 2 (2). Can perform the functions.

  In the electronic musical instrument according to one embodiment of the present invention, the pitch storage means 2a for storing pitch information based on operations of a plurality of pitch designating operators (performance operators = keyboard 5K) for designating a plurality of pitches is provided. Provided. Enter key-alternating mode and specify a setting function that includes control parameter value settings such as tempo, volume, tone, etc., selection of elements on screen 6S, such as music selection, page jump, etc. Parameter value setting and screen element selection can be specified), and pitch information is stored in the pitch storage means 2a in response to a user operation of the performance operator 5K, and the pitch of the stored pitch information is obtained. Accordingly, the control parameter value can be set and the screen element can be selected. Furthermore, when the set control parameter value or screen element selection state is confirmed based on the user operation, control corresponding to the control parameter is executed according to the confirmed control parameter value, or the setting function designated according to the confirmed element selection Execute.

[Operation flow example]
4 to 7 are flowcharts showing operations based on electronic musical instrument processing according to an embodiment of the present invention, and FIGS. 4 and 5 are overall operational flows of electronic musical instrument processing. When the electronic musical instrument process is started by turning on the power of the electronic musical instrument, the CPU 1 first initializes in step S1 so that the operation input by the user can be accepted for the buttons, switches, sliders, and the like of the input operation unit 5. In the subsequent step S2, it is determined whether or not the user has instructed the start of the key pressing alternative mode by operating the key pressing alternative mode switch. When the start of the key pressing alternative mode is instructed (S2 = YES), The key substitution mode is entered, and a pitch information accumulation register: InputData (2a) is set in a predetermined storage area of the RAM 2.

  When the key pressing alternative mode is entered, the process proceeds to step S3, where the operation of the setting operator is checked to determine whether the key pressing pattern acceptance switch has been operated or any other setting operator has been operated. It should be noted that setting operators other than the key pressing alternative mode switch and the key pressing pattern reception switch can designate corresponding functions as setting operators originally prepared in the electronic musical instrument even in the key pressing alternative mode. Here, when another setting operator is operated (S3 = NO), the process proceeds to step S4, and a setting function corresponding to the operated setting operator is extracted.

  On the other hand, when the key depression pattern acceptance switch is operated (S3 = YES), the process proceeds to step S5, the acceptance of the key depression pattern is permitted, and the normal performance is stopped. Therefore, if the performance / playback processing (normal actual performance processing or automatic performance processing) is in progress, this is temporarily suspended and new normal performance is prohibited. In other words, when the key depression pattern acceptance is permitted, the normal performance is temporarily stopped, and the normal performance interruption state is maintained until the key depression alternative mode is ended (until just before step S18 described later). The sound and the key-press sound for setting the musical instrument environment are not mixed. After the normal performance stop process in step S5, the process proceeds to step S6.

  In steps S6 to S10, pattern corresponding function extraction processing is performed to extract a setting function corresponding to the key pressing pattern. That is, in the first step S6 of the pattern corresponding function extraction process, InputData (2a) is cleared, and in the next step S7, a series of key press input sounds by a user operation is received and pitch information is accumulated in InputData. When pitch information of a predetermined amount (for example, three sounds) is accumulated, in a subsequent step S8, the key press pattern table PT is referred to search for a setting function corresponding to the pitch string accumulated in InputData, and in step S9, It is determined whether or not the key pressing pattern table PT has a setting function corresponding to the pitch string of InputData. Here, when it is determined that there is no setting function corresponding to the InputData pitch sequence (S9 = NO), the process proceeds to step S10, and there is no setting function corresponding to the input key pressing pattern by voice or display. To the user and asks the user whether or not to press the key again. Here, if a key operation input is instructed by the user operation (S10 = YES), the process returns to step S6, and steps S6 to S10 are repeated while the key input input is instructed.

  After extracting the setting function by the operation of the setting operator in step S4, or when it is determined in step S9 that there is a setting function corresponding to the InputData pitch sequence and this is extracted (S9 = YES), step S11 Then, it is determined whether or not the extracted setting function is the first type function to be executed as it is. Here, when it is a 1st type (S11 = YES), the said setting function is performed by step S12. For example, if “Metronome ON / OFF” is specified when the metronome is on, the metronome is turned off (extracting the setting function to reverse the current setting state) As described above, the first type setting function that can be instructed immediately is executed as it is.

  On the other hand, when it is determined that the extracted setting function is not the first type (S11 = NO), the process proceeds to step S13. Steps S <b> 13 to S <b> 16 are preparation stages for accepting key press inputs according to the second and third type setting functions. Here, if the performance / playback processing is in progress, after the process of temporarily suspending in step S13, the process proceeds to step S14 (FIG. 5), and the extracted setting function is a third type for displaying a screen. It is determined whether it is a function of.

  Here, when it is determined that the function is the second type function only for setting the value of the control parameter (S14 = NO), in step S15, the user sets a desired value for the control parameter corresponding to the extracted setting function. Set to the setting standby state to accept input. In the setting standby state, the value of the control parameter corresponding to the setting function is indicated by the default value or the current setting value, and the user can know the initial value when the control parameter is set. For example, if it is tempo setting, the default or current tempo value is displayed on the tempo value display, and if it is volume setting, the default or current setting tempo value is displayed on the volume value display and the volume level. If the rough level is displayed on the indicator lamp and the tone is set, the default value or the currently set tone value (numerical value and tone name) is displayed on the tone value display and the tone of the category corresponding to this tone value is displayed. The built-in lamp of the selection switch is turned on. Then, the process proceeds to input data processing in step S17.

  On the other hand, when it is determined in step S14 that it is a third type function for displaying a screen (S14 = YES), a screen corresponding to the extracted setting function is displayed on the display of the display unit 6 in step S16. Then, a selection waiting state for accepting selection input of a user-desired element from the screen is made. Also in this case, the value of the element corresponding to the setting function is selected by default, and the user can know the initial value when the element is selected on the screen. For example, if it is a music selection screen, as shown in FIG. 3 (1), the automatic performance data (Song 1) selected by default is highlighted on the music selection screen, and if it is a page selection screen, FIG. 3 (2). As shown, the page (page 2) selected by default is displayed on the top layer. Then, the process proceeds to the input data processing in step S17, and parameter values are set or screen elements are selected by key press input.

  FIG. 6 is a flowchart showing a specific example of the input data processing performed in step S17 of FIG. In the input data processing, first, in step P1, the key input pitch information accumulation register: InputData (2a) is cleared, and in the next step P2, the operation of the keyboard 5K or the setting operator is waited for, and some operation input is performed. Is detected (P2 = YES), the process proceeds to step P3, where it is determined whether or not the detected operation input is a key pressing operation. On the other hand, when the input is a key pressing operation (P3 = YES), the process proceeds to step P4, and the pitch information input by the key pressing operation is examined to determine whether the input is a black key operation or not. Here, when the operation is based on the operation of the white key instead of the black key (P4 = NO), the process proceeds to the white key input process in step P5.

  FIG. 7 is a flowchart showing a specific example of the white key input process performed in step P5 of FIG. In the white key input process, it is determined in the first step Q1 whether InputData (2a) is empty. If InputData is empty (Q1 = YES), the process immediately proceeds to step Q11, and pitch information input by the white key operation is stored at the end of InputData as a value corresponding to the current state, and the white key is input. The time process is terminated, and the process returns to step P2 in FIG.

  On the other hand, if InputData is not empty (Q1 = NO), in step Q2, the pitch information input this time by white key operation is the pitch indicated by the pitch information (white key) at the end (last) of InputData (previous time). Whether the pitch is less than 2 octaves or not is determined. Here, if the current input pitch by the white key operation is less than 2 octaves from the last pitch of InputData (previous input pitch) (Q2 = YES), the process proceeds to step Q7. Steps Q7 to Q10 correspond to the change of the element selection state / parameter value according to the key press input for each white key. First, in step Q7, the number of white keys is calculated from the end pitch of InputData for the current input pitch, the amount of change from the previous input pitch is obtained, and then the end of InputData is determined in step Q8. It is determined whether or not the pitch (previous input pitch) is lower than the current input pitch.

  Here, when “previous input pitch <current input pitch” (Q8 = YES), in step Q9, the current state is updated by adding the amount of change to the current state, and displayed as necessary. Also update. When “previous input pitch> current input pitch” (Q8 = NO), in step Q10, the current state is updated by subtracting the amount of change from the current state, and displayed as necessary. Also update. That is, at step Q9 / Q10, the control parameter value is set by updating the current parameter value to a value that is plus / minus the value corresponding to the amount of change obtained at step Q7. The new tempo value is displayed on the numeric display, and if the volume is set, the new volume value is displayed on the numeric display and the corresponding approximate level is displayed with the level display lamp. Switch to (numerical value and timbre name) and turn on the timbre selection switch of the category corresponding to this timbre value (in this case, for example, if the timbre is changed by program change, the timbre corresponding to each value up to 127 is set. ) Thereby, the user can confirm the update status by the white key operation this time. In addition, for selecting an element on the screen, an element that is in the right / left direction is selected from the currently selected element by a value (number) corresponding to the amount of change obtained in step Q7, and the selected new element However, if it is a song or a page, for example, it is highlighted or displayed on the top layer. In this way, the direction and amount of key depression are reflected in the value.

  Then, after the update process of steps Q9 and Q10, the process proceeds to step Q11, the current input pitch information is stored at the end of InputData, the white key input process is terminated, and the process returns to step P2 of FIG. When the current input pitch is equal to the previous input pitch, the process returns from step Q2 to steps P7 to Q11 without performing any processing.

  If it is determined in step Q2 that the current input pitch is more than two octaves away from the previous input pitch (Q2 = NO), the process proceeds to step Q3. In steps Q3 to Q6, a process for continuing key pressing input (the uppermost stage in FIG. 2 (2)) is performed. First, in step Q3, it is determined whether or not the second pitch from the end of InputData (the input pitch of the previous time) is smaller than the last pitch of InputData (previous input pitch), and subsequent steps Q4 and Q5. Further, it is determined whether or not the pitch at the end of InputData (previous input pitch) is smaller than the current input pitch. If this is the second white key operation and the pitch information is stored only at the end of InputData, the process goes from step Q3 to step Q4 to step Q7.

  Here, when “previous input pitch <previous input pitch” (Q3 = YES) and “previous input pitch <current input pitch” (Q5 = YES) or “previous input pitch> When “previous input pitch” (Q3 = NO) and “previous input pitch> current input pitch” (Q4 = NO), the white key is again in the same direction as the previous key pressing operation direction. Is determined to have been operated, the process proceeds to step Q7, and the same processing as described above is performed in steps Q7 to Q11.

  Also, when “previous input pitch <previous input pitch” (Q3 = YES) and “previous input pitch> current input pitch” (Q5 = NO) or “previous input pitch> previous time” ”Input pitch” (Q3 = NO) and “previous input pitch <current input pitch” (Q4 = YES), this time the white key is in the opposite direction to the previous key pressing operation direction. It is determined that it has been operated, and the process proceeds to Step Q6. In step Q6, according to the special key pressing rule, the reference tone for continuation of key pressing input in FIG. 2 (2) is determined, InputData is cleared, and the current input pitch information is stored at the end of InputData. Then, the white key input process is terminated, and the process returns to Step P2 in FIG.

  Returning to the input data processing of FIG. 6, when it is determined in step P4 that a black key operation input has been made (P4 = YES), the process proceeds to step P6, and the pitch information stored in InputData is two or more. If the pitch information is 0 (InputData is empty) or 1 (P6 = NO), in step P8, the current status (default value, 1 (In this case, the value corresponding to the pitch of InputData) determines the element selection state or control parameter value, ends the selection or setting standby state, and executes the setting function with the determined content.

  When it is determined in step P6 that there are two or more pitch information of InputData (P6 = YES), the process proceeds to step P7, and the input pitch (black key) is one octave from the pitch information at the end of InputData. It is determined whether or not they are separated. Here, when the input pitch of the black key is within one octave of the end pitch of InputData (P7 = NO), it corresponds to the “determined” special key pressing operation. The element selection state or control parameter value is finalized (the value corresponding to the pitch at the end of InputData), the standby state is terminated, and the “confirmation process” is executed to execute the setting function with the confirmed content. If the black key input pitch is more than one octave away from the end pitch of InputData (P7 = YES), it corresponds to the special key-pressing operation of “Cancel”. The “cancel process” for ending the standby state is performed as is.

  If it is determined in step P3 that there is an operation input from a setting operator such as a button or slider instead of a key pressing operation (P3 = NO), whether or not InputData is empty is determined in step P10. judge. If InputData is empty (P10 = YES), it is determined in step P11 whether or not the operation input corresponds to “confirm”, that is, the one corresponding to “confirm”, that is, the confirm button DF. When the above operation is performed (P11 = YES), the process proceeds to step P8 and the above-described determination process is performed. When the operation input does not correspond to “confirm” (P11 = NO), it is determined in step P12 whether or not it corresponds to “cancel”, and the one corresponding to “cancel”, that is, the cancel button CA. When the operation is performed (P12 = YES), the process proceeds to Step P8 and the above-described canceling process is performed.

  When the operation input does not correspond to “cancel”, that is, when there is an input for selecting a screen element or a control parameter value by operating the setting operator for the designated setting function ( In step P13, the current state (selected state / value) is updated in accordance with the operation input, the corresponding display is updated as necessary, and the process returns to step P2. That is, in steps P11 → P12 → P13, it is possible to select an element and set a control parameter value by operating only the setting operator.

  If it is determined in step P10 that it is not empty (P10 = NO), the process returns to step P2. That is, while an element is selected or a control parameter value is set by a key pressing operation, element selection or value setting by an operation of another setting operator is not accepted.

  As described above, when the confirmation process in step P8 or the cancellation process in step P9 is performed, the input data process (S17: FIG. 5) is completed, the operation in the key-push substitution mode is also completed, and step S18 in the electronic musical instrument process is completed. Go to (Fig. 5). Further, when there is no instruction for re-keying input in step S10 (FIG. 4) of the electronic musical instrument processing (S10 = NO) or after the first type setting function is executed in step S12, the operation in the key pressing alternative mode is performed. End and proceed to step S18.

  In step S18, normal performance is permitted, and if the performance / reproduction processing is temporarily suspended, the performance / reproduction processing is resumed. After the processing of step 18 or when the start of the key pressing alternative mode is not instructed in step S2 (S2 = NO), the process proceeds to step S19, and processing other than in the key pressing alternative mode, for example, a new performance / While the reproduction process and the key pressing pattern table PT are changed and the power is on (S20 = NO), the processes of steps S2 to S19 are repeated. When the power is turned off (S20 = YES), an end process is performed in step S21, and then the electronic musical instrument process 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, in the embodiment, the electronic musical instrument is allowed to accept the key depression pattern using the dedicated key depression pattern acceptance switch. However, other button combination operations may be used, or the keyboard (5K) may be used. A special key pressing pattern such as simultaneous key pressing of the highest and lowest sounds may be used.

  The setting function is not limited to the song selection function, tempo value setting, page jump, and the like of the embodiment. In addition, with regard to the change width of the key press, in the embodiment, only the white key is used and the element is selected and the value is set by the number of the white keys. Good. Furthermore, in the embodiment, the value set by pressing the white key and the element to be selected are changed, and “determined (determined)” is determined by operating an appropriate black key nearby. The “operation” may be, for example, another switch installed near the keyboard, or may be a “confirm” operation when no key pressing operation is performed for a certain time such as one minute.

  When the setting function (item) is specified by a key pressing pattern, the key pressing following the key pressing pattern that can be determined may be applied to the setting of the value of the setting function.

  When setting a control parameter value by pressing the key, the value is actually changed from the second pressed key as the reference for starting the setting of the first pressed key, and the value / selected state is moved by one by pressing the first key. You may do it. Alternatively, the reference position may be determined in advance as C3, for example, and the value may be changed from the first key depression. In addition, when two sounds are pressed almost simultaneously, the distance between the two sounds may be reflected in the value. Also, in accordance with the type of parameter to be set (tempo, volume, etc.), a table is prepared in which each pitch is associated with a set value. After the key, the value may be changed according to the distance from the previous key press (number of white keys or semitone distance).

  Not only the pitch but also rhythm (timing, length, etc.) elements may be incorporated into the key-press pattern to be registered. The key pressing pattern table (PT) and the key pressing alternative rule (RL) may be editable by the user.

  In the embodiment, the number of white keys and the change width of the values are made the same. However, for example, the value and the selection state may be changed by a plurality of times the number of white keys. Further, when the value reaches the limit value, control may be performed so that the limit value is not exceeded even if there is a key press (white key).
