Therefore, in the following description, as shown in FIG. 2B, when the keyboard display device 24 is provided below the key 22, the “keyboard display device 24 corresponding to the key 22” is “the key 22 of the keyboard display device 24. "Display part corresponding to".

  FIG. 3 is a schematic plan view showing an example of display by the keyboard display device 24 according to the embodiment of the present invention. 3A shows a display example of the normal performance mode, FIG. 3B shows a music selection mode, FIG. 3C shows a performance control mode, and FIG. 3D shows a tone color selection mode. Switching between modes is performed using the mode switch 12. It should be noted that a specific key (for example, the lowest tone key, the highest tone key, etc.) may be used as the mode change switch 12 instead of the mode change switch.

  In the normal performance mode, nothing is displayed on the keyboard display device 24 as shown in FIG.

  In the song selection mode, as shown in FIG. 3B, the keyboard display device 24 corresponding to the key of the lowest tone is currently displayed as being in the song selection mode, and the keyboard display device corresponding to each subsequent key is displayed. 24 displays music data (selectable by the user) stored in the electronic musical instrument 1. The music data is selected by operating (pressing) the key 22 on which the desired music data is displayed.

  In the performance control mode, as shown in FIG. 3C, the keyboard display device 24 corresponding to the key of the lowest tone is displayed as being currently in the performance control mode, and the keyboard display device corresponding to each subsequent key. Reference numeral 24 indicates parameters such as the current volume value, tempo value, and the like, and command for reproducing and stopping music data. By operating (pressing) the key 22 on which a desired command is displayed, the command is executed.

  In this embodiment, the velocity value when the key 22 on which the parameters (volume, tempo, etc.) are operated is detected, and the corresponding parameter is changed based on the detected velocity value. For example, when the key 22 to which the volume parameter is assigned is operated, the detected velocity value may be used as it is as the volume parameter value, or the detected velocity value may be multiplied by a predetermined coefficient as the volume parameter value. good.

  The change of the parameter value is not limited to the velocity value of the corresponding key. For example, the parameter value may be changed by an aftertouch value. When the key 22 having the position detection function is used, the operation position of the key 22 is changed. The volume value may be determined based on the above. Furthermore, an up / down switch for setting the upper and lower parameters may be displayed on the key 22.

Also good. In this case, as in the above example, parameters, commands, etc. are assigned to each key 22, and the parameters, commands, etc. are displayed on the keyboard display device 24 corresponding to each key 22, to which the parameters, commands, etc. are assigned.

  FIG. 4 is a flowchart showing main processing of the electronic musical instrument 1 according to the embodiment of the present invention. This main process is started when the electronic musical instrument 1 is turned on.

  In step SA1, the main process is started. In step SA2, the mode variable on the RAM 7 (FIG. 1) is initialized to “normal performance mode”. The mode variables are, for example, “0” in “normal performance mode”, “1” in “music selection mode”, “2” in “performance control mode”, and “3” in “tone selection mode”.

  In step SA3, the operation of the mode selection switch 12 (FIG. 2) is detected, and “1” is added to the mode variable in the RAM 7. However, when the addition result reaches the number of modes (here, 4), it returns to “0”. If no operation is detected, the process proceeds to the next step SA4. Thereafter, in step SA4, the process is distributed according to the current mode variable. If the mode variable is “0”, the normal performance mode process in step SA5 is performed. If “1”, the music selection mode process in step SA6 is performed. If “2”, the performance control mode process in step SA7 is performed. In the case of “3”, the process proceeds to the timbre selection mode process of step SA8. When each mode process ends, the process proceeds to step SA9. Details of each mode process will be described later.

  In step SA9, other processing is performed. Here, the other processing is processing other than each mode processing from step SA5 to step SA8, for example, editing of various data stored in the electronic musical instrument 1, communication setting, setting of various functions, and the like. Yes, it is the setting or execution of each function provided in the normal electronic musical instrument 1. Thereafter, the process returns to step SA3 and the subsequent processing is repeated. In this main process, the processes in steps SA3 to SA9 are repeated until the electronic musical instrument 1 is powered off.

  FIG. 5 is a flowchart showing the normal performance mode process executed in step SA5 of FIG.

  In step SB1, normal performance mode processing is started, and in step SB2, it is determined whether or not the mode is a transition from another mode. That is, it is detected whether or not the current normal performance mode process has been started as a result of the mode change being performed by detecting the operation of the mode switch 12 in step SA3 in FIG. If it is determined that the transition is from the other mode, the process proceeds to step SB3 indicated by an arrow of YES. If the transition is not from the other mode, that is, if the normal performance mode process is continuously started, NO is determined. The process proceeds to step SB5 indicated by an arrow.

  In step SB3, the display on the keyboard display device 24 (FIGS. 1 and 2) is erased and initialized. Thereby, the image (for example, display of FIG. 3 (B)-(D)) of the former mode (mode before transition) process is erase | eliminated. Thereafter, in step SB4, all performance operators (keys) 22 are set in a playable state. That is, various parameters, commands, and the like assigned to the performance operator are initialized, and a musical sound corresponding to the operation of the performance operator 22 can be generated. When a specific key 12 is used as the mode switch 12, the mode switch command assignment to the specific key 12 may not be canceled.

  In step SB5, the user's performance operation on the performance operator 22 is detected. If a performance operation is detected, the process proceeds to step SB6 indicated by an arrow of YES, and a musical sound corresponding to the performance operation for the performance operator 22 for which the performance operation is detected is generated. If no performance operation is detected, the process proceeds to step SB7 indicated by an arrow of NO, the normal performance mode process is terminated, and the process returns to step SA9 in FIG.

  FIG. 6 is a flowchart showing the music selection mode process executed in step SA6 of FIG. Here, description is made on the assumption that display corresponding to FIG. 3B is performed.

  In step SC1, the music selection mode process is started, and in step SC2, it is determined whether or not the mode is a transition from another mode. That is, it is detected whether or not the current music selection mode process is activated as a result of the mode change being detected by detecting the operation of the mode switch 12 in step SA3 of FIG. If it is determined that the transition is from the other mode, the process proceeds to step SC3 indicated by an arrow “YES”. If the transition is not from the other mode, that is, if the music selection mode process is continuously started, NO is selected. The process proceeds to step SC8 indicated by an arrow.

  In step SC3, the display on the keyboard display device 24 (FIGS. 1 and 2) is erased and initialized. As a result, the image of the previous mode (mode before transition) process (for example, the display of FIGS. 3C and 3D) is deleted. Thereafter, the character string “SONG SELECT MODE” is displayed on the keyboard display device 24 corresponding to the key of the lowest pitch (for example, A2).

  In step SC4, all song files (song data) stored in the external storage device 15 or ROM 8 of the electronic musical instrument 1 are searched, and a song table STB including the path to the detected file is stored on the RAM 7 (FIG. 1). To create. For example, as shown in FIG. 9, the song table STB is a reference table that records a note number and a path to a song file in association with each other. Note that the song table STB may be prepared in advance in the external storage device 15 or the ROM 8, or may be created when a new song is stored in the electronic musical instrument 1 or may be added to a previously created song table STB.

  In step SC5, the music table STB stored in the RAM 7 or ROM 8 is referred to, a character string representing the music name is acquired from the music file specified by the file path in the recording order in the music table STB, and the acquired character string is acquired. Is displayed on the keyboard display device 24 corresponding to the key 22 represented by the note number.

  In step SC6, the display mode of the keyboard display device 24 corresponding to the key 22 corresponding to the currently selected song file is made different from the display mode of the keyboard display device 24 corresponding to the other keys 22. For example, the music title display is underlined.

  In step SC7, the display mode of the keyboard display device 24 corresponding to the key 22 within the music selection range (for setting operation) is changed to the display mode of the keyboard display device 24 corresponding to the key 22 outside the music selection range (for performance operation). Different from. For example, keys that are within the song selection range are all lit brightly except for characters, and keys that are outside the song selection range are turned off. The key 22 in the music selection range is a key to which a music file is assigned. The music file allocation may be performed using all the keys 22, or only a predetermined number of keys 22 from the low sound side or the high sound side may be set as the music selection range. Further, a predetermined number of keys 22 from both the low sound side and the high sound side may be used as the music selection range.

  In step SC8, the presence / absence of a user operation on the key 22 within the song selection range (for setting operation) is detected. If an operation is detected, the process proceeds to step SC9 indicated by a YES arrow, and if no operation is detected, the process proceeds to step SC11 indicated by a NO arrow.

  In step SC9, a file path corresponding to the note number of the key 22 whose operation is detected in step SC8 is acquired with reference to the music table STB. Thereafter, in step SC10, the automatic performance unit is instructed to play the music file specified by the file path acquired in step SC9. An automatic performance unit (not shown) is a well-known automatic performance program that is simultaneously executed in the main process, various mode processes, and time-division processing, and is realized by the CPU 9, the ROM 8, the RAM 7, and the like.

  In step SC11, it is detected whether or not the user performs a performance operation on the key 22 outside the music selection range (for performance operation). If an operation is detected, the process proceeds to step SC12 indicated by a YES arrow, and a musical sound corresponding to the performance operation on the performance operator 22 for which the performance operation is detected is generated. If the performance operation is not detected, the process proceeds to step SC13 indicated by the arrow of NO, the music selection mode process is terminated, and the process returns to step SA9 in FIG.

  FIG. 7 is a flowchart showing the performance control mode process executed in step SA7 of FIG. Here, description is made on the assumption that display corresponding to FIG.

  In step SD1, performance control mode processing is started, and in step SD2, it is determined whether or not the mode is a transition from another mode. That is, it is detected whether or not the current performance control mode process is activated as a result of the mode change being detected by detecting the operation of the mode switch 12 in step SA3 in FIG. If it is determined that the transition is from the other mode, the process proceeds to step SD3 indicated by an arrow “YES”. If the transition is not from the other mode, that is, if the performance control mode process is continuously started, NO is determined. The process proceeds to step SD8 indicated by an arrow.

  In step SD3, the display on the keyboard display device 24 (FIGS. 1 and 2) is erased and initialized. Thereby, the image (for example, display of FIG. 3 (B), (D)) of the former mode (mode before transition) process is deleted. Thereafter, the character string “PLAY CONTROL MODE” is displayed on the keyboard display device 24 corresponding to the key of the lowest pitch (for example, A2).

  In step SD4, “VOLUME”, “STOP”, “CONTINUE”, “START” are sequentially displayed on the keyboard display device 24 corresponding to the key (eg, B2 to F3) higher than the key of the lowest pitch (eg, A2). ”And“ TEMPO ”are displayed. The command for executing various processes displays the command name here and assigns the command to the key 22.

  In step SD5, the current volume parameter value is acquired, the acquired parameter value (numerical value) and a graph corresponding to the parameter value are displayed, and the key 22 (the key of B2) in which the character string “VOLUME” is displayed in step SD4. Is displayed on the keyboard display device 24 corresponding to.

  In step SD6, the current tempo parameter value is acquired, the acquired parameter value (numerical value) and a graph corresponding to the parameter value are displayed, and the key 22 (the key of F3) displaying the character string “TEMPO” in step SD4. Is displayed on the keyboard display device 24 corresponding to.

  In step SD7, the display mode of the keyboard display device 24 corresponding to the key 22 within the performance control range (for setting operation) is changed to the display mode of the keyboard display device 24 corresponding to the key 22 outside the performance control range (for performance operation). Different from. For example, for keys within the performance control range, all keys other than graphs and letters are lit brightly, and keys outside the performance control range are turned off. The key 22 within the performance control range is a key to which a parameter or command is assigned. The parameters and commands may be assigned using all the keys 22 or only a predetermined number of keys 22 from the bass side or the treble side may be used as the performance control range. Further, a predetermined number of keys 22 from both the low sound side and the high sound side may be used as the performance control range.

  In step SD8, the presence / absence of a user operation on the key 22 (B2 key) displaying the character string “VOLUME” in step SD4 is detected. If an operation is detected, the process proceeds to step SD9 indicated by a YES arrow, and if an operation is not detected, the process proceeds to step SD11 indicated by a NO arrow. The detection here is determined, for example, based on whether or not the MIDI note number generated by the key operation is the tendon note number (“47” in the case of B2) corresponding to the volume operation.

  In step SD9, the velocity value of the key operation detected in step SD8 is acquired, and the volume parameter value is updated with the acquired velocity value. For updating the parameter value, the detected velocity value may be used as the volume parameter value as it is, or the detected velocity value may be multiplied by a predetermined coefficient to obtain the volume parameter value. The values acquired here are not limited to velocity values, but can be changed by key operations such as aftertouch, note-on to note-off time, frequency of note-on / off per unit time, etc. Anything is acceptable.

  In step SD10, the current volume parameter value updated by the process in step SD9 is acquired, the acquired parameter value (numerical value) and a graph corresponding to the parameter value are displayed, and the character string “VOLUME” is displayed in step SD4. Display on the keyboard display device 24 corresponding to the key 22 (B2 key).

  In step SD11, the presence or absence of a user operation on the key 22 (F3 key) displaying the character string “TEMPO” in step SD4 is detected. If an operation is detected, the process proceeds to step SD12 indicated by an arrow of YES, and if an operation is not detected, the process proceeds to step SD14 indicated by an arrow of NO. The detection here is determined by, for example, whether or not the MIDI note number generated by the key operation is the tendon note number corresponding to the tempo operation (“53” in the case of F3).

  In step SD12, the velocity value of the key operation detected in step SD11 is acquired, and the tempo parameter value is updated with the acquired velocity value. The parameter value may be updated by using the detected velocity value as it is as the tempo parameter value or by multiplying the detected velocity value by a predetermined coefficient to obtain the tempo parameter value. The values acquired here are not limited to velocity values, but can be changed by key operations such as aftertouch, note-on to note-off time, frequency of note-on / off per unit time, etc. Anything is acceptable.

  In step SD13, the current tempo parameter value updated by the process in step SD12 is acquired, the acquired parameter value (numerical value) and a graph corresponding to the parameter value are displayed, and the character string “TEMPO” is displayed in step SD4. Displayed on the keyboard display device 24 corresponding to the key 22 (F3 key).

  In step SD14, the presence / absence of a user operation on the other keys 22 (keys other than B2 and F3) within the performance control range (for setting operation) is detected. If an operation is detected, the process proceeds to step SD15 indicated by a YES arrow, and if an operation is not detected, the process proceeds to step SD16 indicated by a NO arrow.

  In step SD15, the command assigned to the key 22 whose operation is detected in step SD14 is executed. For example, when there is an operation on the key 22 displaying the character string “PLAY”, the automatic performance is started.

  In step SD16, it is detected whether or not the user performs a performance operation on the key 22 outside the performance control range (for performance operation). If an operation is detected, the process proceeds to step SD17 indicated by a YES arrow to generate a musical sound corresponding to the performance operation for the performance operator 22 for which the performance operation has been detected. When the performance operation is not detected, the process proceeds to step SD18 indicated by a NO arrow, the performance control mode process is terminated, and the process returns to step SA9 in FIG.

  When parameter values other than volume and tempo are displayed on the keyboard display device 24, the parameter name of the parameter value is displayed on the keyboard display device 24 corresponding to the arbitrary key 22 in step SD4, and step SD5 or step SD6 is displayed. The parameter value is displayed in the same way as. Further, the displayed parameter value can be edited by the same processing as in steps SD8 to SD10 or steps SD11 to SD13.

  Further, when a command other than the above-described automatic performance-related commands is displayed on the keyboard display device 24, the command name of the command is displayed on the keyboard display device 24 corresponding to an arbitrary key 22 and the key 22 is displayed in step SD4. The command can be assigned to and the command can be executed by the processing of steps SD14 to SD15.

That is, it is detected whether or not the current timbre selection mode process is activated as a result of the mode change being performed by detecting the operation of the mode changeover switch 12 in step SA3 in FIG. If it is determined that the transition is from the other mode, the process proceeds to step SE3 indicated by an arrow “YES”. If the transition is not from the other mode, that is, if the timbre selection mode process is continuously started, NO is determined. Proceed to step SE7 indicated by an arrow.

  In step SE3, the display on the keyboard display device 24 (FIGS. 1 and 2) is erased and initialized. Thereby, the image (for example, the display of FIG. 3 (B), (C)) of the previous mode (mode before transition) process is deleted. Thereafter, the character string “VOICE SELECT MODE” is displayed on the keyboard display device 24 corresponding to the key of the lowest pitch (for example, A2).

  In step SE4, referring to the timbre control table VCT stored in the external storage device 15 or the ROM 8 of the electronic musical instrument 1, each timbre name corresponds to the key 22 represented by the note number associated with each timbre. Displayed on the keyboard display device 24. For example, as shown in FIG. 10, the timbre control table VCT is a reference table that records a note number, a timbre number that can be selected by the electronic musical instrument 1, and a timbre name corresponding to the timbre number.

  In step SE5, the display mode of the keyboard display device 24 corresponding to the key 22 corresponding to the currently selected tone color is made different from the display mode of the keyboard display device 24 corresponding to the other keys 22. For example, the note name display is underlined.

  In step SE6, the display mode of the keyboard display device 24 corresponding to the key 22 within the timbre selection range (for setting operation) is changed to the display mode of the keyboard display device 24 corresponding to the key 22 outside the timbre selection range (for performance operation). Different from. For example, keys that are within the timbre selection range are all lit brightly except for characters, and keys that are outside the timbre selection range are turned off. The key 22 in the timbre selection range is a key to which a timbre is assigned. The timbre assignment may be performed using all the keys 22 or only a predetermined number of keys 22 from the low tone side or the high tone side may be set as the tone color selection range. Further, a predetermined number of keys 22 from both the low tone side and the high tone side may be used as the tone color selection range.

  In step SE7, the presence / absence of a user operation on the key 22 within the timbre selection range (for setting operation) is detected. If an operation is detected, the process proceeds to step SE8 indicated by an arrow “YES”, and if an operation is not detected, the process proceeds to step SE10 indicated by an arrow “NO”.

  In step SE8, the timbre number corresponding to the note number of the key 22 whose operation is detected in step SE7 is acquired with reference to the timbre control table VCT. Thereafter, in step SE9, the timbre number acquired in step SE8 is set in the sound source unit (sound source circuit 18 in FIG. 1).

In step SE10, it is detected whether or not the user performs a performance operation on the key 22 outside the timbre selection range (for performance operation). If an operation is detected, the process proceeds to step SE11 indicated by an arrow of YES, and a musical sound corresponding to the performance operation for the performance operator 22 for which the performance operation is detected is generated. If the performance operation is not detected, the process proceeds to step SE12 indicated by an arrow of NO, the timbre selection mode process is terminated, and the process returns to step SA9 in FIG.
In the above timbre selection process, the timbre name is directly selected. However, the timbre is divided into categories for each instrument type, and individual timbres are selected by selecting from the higher layers in order. Anyway. For example, first select an instrument type such as "Plucked string instrument", "Percussion instrument", "Woodwind instrument", "Brass instrument", etc. Then, for example, from "Brass instrument", "Trumpet", "Trombone", An instrument name such as “horn” may be selected, and finally, for example, a trumpet variation of individual instruments such as “trumpet 1” and “trumpet 2” may be selected from “trumpet”. In this case, a timbre control table is prepared for each layer, each option in the upper timbre control table is associated with the lower timbre control table, and the lowest timbre control table is as shown in FIG. And At this time, in step SD8, the timbre number or the identifier of the timbre control table is acquired, and when the identifier of the timbre control table is acquired in step SD8, the display on the keyboard display device 24 is updated by returning to step SD4. You can do it. In addition, such hierarchization can be performed in the same manner in other modes of processing.

  As described above, according to the embodiment of the present invention, since the display function corresponding to each key of the keyboard device is incorporated, it is possible to display commands, function options, and parameters on each key in accordance with the setting operation mode of the musical instrument. . Therefore, the number of operators on the setting panel can be greatly reduced, and it is not necessary to print the correspondence between keys and parameters, and the appearance of the electronic musical instrument can be made clean. Moreover, the freedom degree in exterior design can be improved. Furthermore, it is possible to cope with various or complicated setting operation modes.

  Further, according to the embodiment of the present invention, since commands, parameters, and the like assigned to the key are displayed on the key itself, the operation is intuitive and easy for the user to understand. In addition, since the parameter value can be displayed as a key, the current parameter value can be easily understood.

  Furthermore, according to the embodiment of the present invention, the key velocity such as the velocity of the operation to which the parameter is assigned, the after touch, the time from note-on to note-off, the frequency per unit time of note-on / off, etc. The value of the parameter can be changed depending on the value that can be changed. Therefore, the user can intuitively change the parameter.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.
