  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a diagram showing a front panel of an electronic musical instrument which is a musical sound generator according to an embodiment of the present invention. Here, an electronic organ is assumed as the electronic musical instrument 1, but the present invention is not limited to this. The electronic musical instrument 1 has a keyboard device 4 including an upper keyboard 2 and a lower keyboard 3. Further, the keyboard device 4 includes a pedal keyboard (not shown) arranged at the lower part of the electronic musical instrument 1 instead of the front panel. On the left side and upper side of the keyboard device 4 (in this specification, the side far from the performer is described as “up” and the side close to the performer is described as “down” in the top view of the electronic musical instrument 1) Arranged.

  The control panel 5 includes a display device 6 located substantially in the center, and an operation unit 7 provided on the left and right of the display device 6 and on the left side of the keyboard device 4. The display device 6 displays each setting state and operation state of the electronic musical instrument 1. The operation unit 7 includes a timbre selection unit 8, a draw bar 9, an automatic performance operation unit 10, a keyboard conductor 11, and an increment dial 12. A main switch 100 is provided to the right of the increment dial 12, and speakers 33 are provided to the left and right of the control panel 5.

  The timbre selection unit 8 has a plurality of timbre setting buttons and a setting button such as a volume provided for each of the timbre series of the upper keyboard 2, the lower keyboard 3, and the pedal keyboard (details will be described later). The keyboard conductor 11 is a group of switches that enable dynamic arrangement according to the musical composition by intensively controlling on / off of the timbre sequence selected by the timbre selection unit 8 during performance (see FIG. 4). . The timbre series can be set to 6 series for the upper keyboard 2 and the lower keyboard 3 and 4 series for the pedal keyboard.

  FIG. 3 is a diagram showing an example of a switch of the timbre selection unit 8, and shows a timbre selection unit of the first solo (upper solo 1) among a plurality of timbres provided for the upper keyboard 2 as an example. The upper solo 1 is provided with a tone selection switch 13 for selecting flute, saxophone, violin, cosmic (synthesizer), oboe, trumpet, guitar, and all of these tone series, and a volume setting button 14 for each tone. An effect / setting switch 15 and a portamento setting switch 16 are provided. When one of the timbre selection switches 13 is turned on to select a timbre (for example, a violin), a global mode screen is displayed on the display device 6, and a range for setting the selected timbre (violin) is set from the screen. be able to.

  FIG. 3 shows an example of a switch relating to the first solo in the timbre selection unit 8, and the upper keyboard 2 and the lower keyboard 3 include the second solo, the first orchestra as the timbre series in addition to the first solo, Second orchestra, special, and tibia percussion will be provided. Further, the first solo, the second solo, the orchestra, and the tibia are set as the tone color series on the pedal keyboard. The listed timbres are examples, and the timbres set for the upper keyboard 2, the lower keyboard 3, and the pedal keyboard are not limited to these.

  FIG. 4 is a diagram of the keyboard conductor 11. In FIG. 4, the keyboard conductor 11 is composed of 16 switches 11a to 11p corresponding to the timbre series set for each of the upper keyboard 2, the lower keyboard 3, and the pedal keyboard. For the lower keyboard 3, since buttons are set in the same manner as the upper keyboard 2, a part of the illustration is omitted. By turning on these switches 11a to 11p, it is possible to generate sound with the timbre set by the timbre selection sections 8 to 10. For example, the switch 11o is pressed to enable sound generation with the tone color (for example, violin) set in the upper solo 1 shown in FIG. As a result, the violin sound can be produced within the set range. Further, when the switches 11a to 11p are turned on, a sound range that can be generated with the tone color assigned to the turned-on switch is displayed on the display device 6. A display example of the sound range will be described later.

  FIG. 5 is a diagram illustrating an example of the display device 6. The display device 6 includes a liquid crystal display panel (LCD) 17, left and right selection switches 18 L and 18 R used for setting / changing information displayed on the LCD 17, and a lower function switch 19. A plurality of selection switches 18L and 18R and function switches 19 are provided on the left and right and below the LCD 17, respectively, corresponding to the information display positions in the LCD 17, respectively. FIG. 5 is a diagram showing the display device 6 on which the “zone” editor screen is displayed as an example of the global mode. The “zone” refers to a tone range that can be generated with the tone color assigned by the tone color selection unit 8.

  On the zone editor screen, which range of keys of the keyboard device 4 is played and which tone color can be generated is displayed. In this example, the LCD 17 shows five types of keyboard graphics in which a tone color series soundable region set in the upper keyboard 2 is set. Here, the first solo (SLO1), second solo (SOLO2), first orchestra (ORCH1), second orchestra (ORCH2), and special (SPECIAL) zones are displayed in order from the top. In this example, the zone set for the first solo (SOLO1) and special (SPECIAL) is indicated by a horizontal line drawn below the corresponding portion of the keyboard figure. An example of the display related to the zone will be described later.

  Tone assignment using the switches shown in FIGS. 3 and 4 can be performed as follows. With the power turned on, first, the tone color selection switch 13 of the tone color selection unit 8 is turned on to select the tone color to be set. As a result, as shown in FIG. 6, a screen for setting the upper and lower limits of the zone is displayed on the LCD 17 of the display device 6. In FIG. 6, a zone upper limit key screen (ZONE HIGH KEY) for setting an upper limit is displayed. Since the default value key is initially displayed on this screen, the switch 18R (R5) located beside the display is turned on, and the increment dial 12 is rotated. Then, the key names are switched in order, so that the dial operation is stopped when the desired key name is reached, and the effect / setting switch 15 is turned on. As a result, the upper limit of the zone is determined, and then the zone lower limit key screen (ZONE LOW KEY) for setting the lower limit on the display device 6 is displayed on the lower left portion of the LCD 17 (not shown). The lower limit of the zone is determined using the switch 18L (L5) and the increment dial 12 corresponding to the position where the key screen is displayed. When the zone is set, the effect / setting switch 15 is turned on to confirm the setting. As a result, the selected tone color is assigned to the set zone.

  The display of the zone is not limited to the form shown in FIG. FIG. 7 is a diagram showing a display example of the set zones. In FIG. 7, a zone for one tone color series is displayed on the LCD 17. In FIG. 7, a keyboard shape figure 2A, a display indicating that the keyboard is the upper keyboard 2 ([KBD] Upper), a display indicating that the tone series is special ([CND] Special), and setting A display (G 1 -F # 4) indicating the zone being displayed is displayed on the LCD 17. Further, in the keyboard shape figure 2A, the zone is clarified by making the display form of the key different between the zone and the non-zone. For example, in a portion other than between G1 and F # 4, the color of the white key and the black key is reversed, the white key is displayed in black, and the black key is displayed in white. Between G1 and F # 4, the white key is displayed in white and the black key is displayed in black according to the actual key color. The keyboard figure of FIG. 7 may be displayed on the LCD 17 for a single timbre sequence, or the display form of FIG. 7 is adopted when a plurality of timbre sequences are displayed on one screen as shown in FIG. May be.

  The display of the zone is not limited to that performed on the LCD 17. FIG. 8 is a diagram showing a modification of the zone display. In this example, a light emitting element (for example, LED) is provided corresponding to each key of an actual keyboard, and a zone is displayed by turning on or off the LED. FIG. 8 shows an example of the upper keyboard 2. LED rows 20 and 21 are provided in association with the keys of the upper keyboard 2. The LED string 20 is disposed above the upper keyboard 2 corresponding to the black key, and the LED string 21 is disposed below the upper keyboard 2 corresponding to the white key. Among these LED rows 20 and 21, those included in the zone are turned on, and the others are turned off. This clearly distinguishes between zones and non-zones. In FIG. 8, black circles indicate LEDs that are turned on, and white circles indicate LEDs that are turned off.

  FIG. 9 is a system configuration diagram of the electronic musical instrument 1. The electronic musical instrument 1 includes a CPU 23, a ROM 24, a RAM 25, an interface 26, and a sound source 27 connected to the system bus 22. The interface 26 is connected to the keyboard device 4, the control panel 5, the display device 6, and an input / output terminal 28 such as MIDI. A digital signal processing device (DSP) 29, a digital / analog conversion circuit (D / A) 30, an amplifier (AMP) 31, and a speaker 33 are electrically connected to the sound source 27. The sound source 27 can have a waveform memory.

  The CPU 23 reads, through the interface 26, the state of each key of the keyboard device 4 (including the pedal keyboard), key release, switches, volumes, and the like provided in the control panel 5 and the display device 6. Then, the sound source 27 is driven in accordance with the read state to generate a musical sound signal. The musical sound signal is input to the DSP 29 and applied with an effect. The output signal of the DSP 29 is converted into an analog signal by the D / A 30 and then input to the speaker 33 via the amplifier 31 and is generated as a musical sound from the speaker 33. The

  FIG. 10 is a flowchart of the main loop process of the electronic musical instrument 1. When the main switch 100 is turned on (for example, pushed down), the power is turned on and the main loop process is started. First, in step S1, a predetermined initialization process is performed. In step S2, it is determined whether an event has been detected. If it is determined that an event has occurred, the process proceeds from step S2 to step S3, and predetermined event processing is performed (an example will be described later). After the event processing, and when no event is detected and step S2 is negative, the process proceeds to step S4. In step S4, time variable processing is performed. The thing variable process is a process for acquiring how much time has passed since the previous process, and is used so that the CPU 23 is interrupted at an interruption time of a predetermined interval. The main loop process is repeated until the main switch 100 is turned off and the power is turned off.

  FIG. 11 is a flowchart of event processing. The event process includes a key press event, a key release event, a switch event, and other processes. In FIG. 11, in step S31, it is determined whether or not the detected event is a key pressing event. If step S31 is affirmative, it will progress to step S32 and a key pressing process will be performed. In the key pressing process, the tone generation channel of the sound source 27 is assigned. If the event is not a key press event, the process proceeds to step S33, and it is determined whether or not the event is a key release event. If step S33 is affirmative, the process proceeds to step S34 to perform a key release process. In the key release process, a channel that is sounding is searched and a process for releasing the channel is performed. It should be noted that a known technique can be used for the key pressing process and the key releasing process, and therefore, detailed description thereof is omitted.

  If it is neither a key press event nor a key release event, the process proceeds from step S33 to step S35, and it is determined whether or not the detected event is a switch event. The switch event refers to the overall processing of the control panel 5, and the presence / absence of the switch event is determined by the presence / absence of a state change of a switch or the like (excluding the main switch 100) of the operation unit 7 provided on the control panel 5. If step S35 is affirmative, the process proceeds to step S36 to perform a predetermined switch process corresponding to the switch whose state has changed (an example will be described later). If step S35 is negative, processing corresponding to another event is performed in step S37. Other processing includes timer event processing, MIDI information reception processing, and the like.

  FIG. 12 is a flowchart of (Process A) as an example of the switch process. In step S41, it is determined whether or not the generated switch event is a switch-on event. If it is a switch-on event, the process proceeds to step S42, and if it is not a switch-on event, the process proceeds to step S43.

  In step S42, it is determined whether or not the switch that has been turned on is the switches 11a to 11p of the keyboard conductor 11. In the flowchart, the switches 11a to 11p are indicated by a symbol KC [n]. [N] is a variable from 0 to 15, and corresponds to 16 switches 11 a to 11 p provided as the keyboard conductor 11. That is, the switch 11a is indicated by KC [0], the switch 11b is indicated by KC [1],... Each of the switches 11a to 11p has an LED as an indicator. When the set timbre series is turned on (soundable), the LED is turned on, and the timbre series is turned off (soundless). When the LED is turned off. If step S42 is positive, the process proceeds to step S44.

  In step S44, the states of the switches 11a to 11p are reversed. That is, the LED provided on the pressed switch is turned on. Along with this, it is possible to generate sound by the tone color assigned to the switch.

  In step S45, the display mode of the LCD 17 is set to the global mode. The display mode includes a global mode, a home mode, and other modes. Home mode is the initial screen when the power is turned on. The global mode is a mode for displaying a tone setting for each key, a zone setting as shown in FIGS. In step S46, the displayed tone color series, that is, the zone display relating to the nth switch of the keyboard conductor 11 is performed.

  If step S42 is negative, that is, if any switch other than the switches 11a to 11p of the keyboard conductor 11 is operated, the process proceeds to step S47. In step S47, it is determined whether or not a switch for setting (or changing) a zone has been turned on. These switches are switches corresponding to the zone upper limit key screen and the zone lower limit key screen, and are the selection switches 18L and 18R and the increment dial 12 in the above-described example. If step S47 is positive, the process proceeds to step S48 to set the upper and lower limits of the zone.

  If the determination in step S47 is negative, the process is for other switches (switches not related to the main part of the present invention). Therefore, the process proceeds to step S49, and a predetermined process corresponding to the ON operation of the switch is performed.

  If step S41 is negative, the switch is turned off. In step S43, whether or not the switch that has been turned off is the nth switch among the switches 11a to 11p of the keyboard conductor 11 is determined. Determined. If step S43 is positive, the process proceeds to step S50, and the display on the LCD 17 is switched to the home mode. That is, among the switches 11a to 11p of the keyboard conductor 11, the timbre series zone display corresponding to the nth switch returns to the home mode screen. Therefore, according to the switch process A, the zone display corresponding to the tone color series is displayed only while the switch of the keyboard conductor 11 is being pressed. If step S43 is negative, the process proceeds to step S51 to turn off other switches. Steps S42 and S43 are determined in order from n = 0 to n = 15.

  FIG. 13 is a flowchart of the switch process B. In FIG. 13, in step S61, it is determined whether or not the generated switch event is a switch-on event. If it is a switch-on event, the process proceeds to step S62, and if it is not a switch-on event, the process proceeds to step S63.

  In step S62, it is determined whether or not the switch that has been turned on is the switches 11a to 11p of the keyboard conductor 11. If step S62 is positive, the process proceeds to step S64. In step S64, the states of the switches 11a to 11p are reversed. This is the same as step S42.

  In step S65, the display mode of the LCD 17 is set to the global mode. In step S66, the timbre series displayed on the global mode screen, that is, the zone display relating to the nth switch of the keyboard conductor 11, is switched.

  In step S67, a predetermined time TL is set in the zone display timer Tz, and time measurement by the zone display timer Tz is started. The zone display is maintained until the zone display timer Tz counts the predetermined time TL.

  If step S62 is negative, the process proceeds to step S68. In step S68, it is determined whether or not a switch for setting (or changing) a zone has been turned on. If step S68 is positive, the process proceeds to step S69 to set the upper and lower limits of the zone. When step S68 is negative, it progresses to step S70 and the predetermined process corresponding to ON operation of other switches is performed.

  Steps S61, S62, S64 to S66, and S68 to S70 are the same processes as steps S41, S32, S44 to S46, and S47 to S49 described with reference to FIG. The switch process B is different from the switch process A in that it includes the process of step S67 and does not include processes corresponding to steps S43 and S50. Therefore, when step S61 is negative, only the switch-off process corresponding to the switch turned off is performed at step S63.

  As described above, in the switch processing B that does not include the step of determining whether the switch that has been turned off is the keyboard conductor 11 switch or the step of returning to the home mode, the global mode is set even if the keyboard conductor 11 switch is turned off. Retained. This global mode is returned to the home mode by a process described later. Accordingly, the zone display is continued in the global mode during that time.

  FIG. 14 is a flowchart showing an example of other processing (step S37) in FIG. In step S71, it is determined whether other processing is a timer event. If it is a timer event, the process proceeds to step S72, and it is determined whether or not the zone display timer Tz set in step S67 has become zero. If it is determined that the zone display timer Tz has become zero, the process proceeds to step S73. In step S73, the display on the LCD 17 is switched to the home mode. That is, when a predetermined zone display time has elapsed, the display of the zone ends and the screen returns from the global mode screen to the home mode screen.

  In step S74, “−1” is set in the zone display timer Tz. Thereby, it is prohibited to perform the process by the value of the zone display timer Tz until the timer value TL is set again in step S67.

  When step S72 is negative, it progresses to step S75 and other timer processing is performed. If step S71 is negative, the process proceeds to step S76 to perform other event processing other than the timer event, for example, processing related to MIDI reception.

  FIG. 15 is a flowchart of the interrupt process. This process is executed every predetermined interrupt time, and detects all states (events) of a plurality of timers provided in the electronic musical instrument 1. In step S81, it is determined whether or not all timer events have been detected based on whether or not the timer identification data Txx is equal to or greater than zero. If step S81 is affirmative, it will progress to step S82 and will decrement the timer identification data Txx (-1). In step S83, an event of the timer Txx is detected. In step S84, it is determined whether all timer events have been detected. If step S84 is positive, the interrupt process ends.

  In the next embodiment (switch processing C), after the switch of the keyboard conductor 11 is pressed, the mode is switched to the global mode after a predetermined time has elapsed and the zone display is performed.

  FIG. 16 is a flowchart of the switch process C. In step S91, it is determined whether or not it is a switch ON event. If step S91 is affirmative, the routine proceeds to step S92, where it is determined whether or not the switch in which the ON event is detected is the nth switch among the 16 switches of the keyboard conductor 11. If step S92 is affirmative, the process proceeds to step S93 to invert the state of the nth switch of the switches 11a to 11p. This is the same as step S44 in FIG. In step S94, a predetermined time TL is set in the zone display timer Tz. That is, in the switch process C, after inverting the switch state, the timer Tz is set and the count is started without immediately shifting to the zone display screen unlike the switch process A and the switch process B.

  If the determination in step S92 is negative, the process proceeds to step S95, and it is determined whether or not the switch for performing the zone setting (or change) of the nth timbre series set in the switches 11a to 11p is turned on. Determine. If step S92 is affirmative, the process proceeds to step S96 to set the upper and lower limits of the zone and change the zone setting. If step S95 is negative, the process proceeds to step S97, and a predetermined process corresponding to an on operation of other switches other than the switch included in the keyboard conductor 11 is performed.

  If step S91 is negative, that is, if it is determined that the switch has been turned off, the process proceeds to step S98. In step S98, it is determined whether or not the switch that has been turned off is the n-th switch of the keyboard conductor 11. If step S98 is affirmative, the process proceeds to step S99 to set "-1" in the zone display timer Tz. If step S98 is negative, the process proceeds to step S100, and a predetermined process corresponding to an off operation of other switches other than the switch included in the keyboard conductor 11 is performed.

  FIG. 17 is a flowchart showing an example of other processing (step S37) when the switch processing C is performed. In step S101, it is determined whether or not other processing is a timer event. If it is a timer event, the process proceeds to step S102, and it is determined whether or not the zone display timer Tz set in step S94 in that timer event has become zero. If it is determined that the zone display timer Tz has become zero, the process proceeds to step S103. In step S103, the display on the LCD 17 is switched to the zone display. That is, when a predetermined zone display time elapses, the timbre series zone corresponding to the nth switch among the switches 11a to 11p of the keyboard conductor 11 is displayed.

  In step 104, “−1” is set in the zone display timer Tz. Thereby, the process based on the value of the zone display timer Tz is not performed until the timer value TL is set again in step S94.

  If step S102 is negative, the process proceeds to step S105 to perform other timer processing. If step S101 is negative, the process proceeds to step S106, and other event processing other than the timer event, such as processing related to MIDI reception, is performed.

  In the switch process C shown in FIGS. 16 and 17, if the ON operation is continued until the time TL when the switch of the keyboard conductor 11 is set in the zone display timer Tz elapses, the display is switched to the zone display. However, the zone display is not performed in the switch operation of the keyboard conductor 11 for a short time which is less than the time TL.

  FIG. 1 is a block diagram showing the main functions of the zone display by the switch process A. In FIG. 1, a timbre assigning means 35 is a means for setting a timbre and a set sound range (zone) in switches 11a to 11p for each timbre series provided as the keyboard conductor 11, and includes a timbre selection section 8, an index dial 12, and a selection. Switches 18L and 18R are included. The allocation contents set by the timbre allocation means 35, that is, the timbres and zones corresponding to the switches 11 a to 11 p are stored in the allocation storage unit 36.

  The switch state detection unit 37 detects whether the switches 11a to 11p of the keyboard conductor 11 serving as sound generation setting switches are turned on or off. When an on operation is detected, an “on detection signal” with identification information of the switch that has been turned on is output. When an off operation is detected, an “off detection signal” with the identification information of the switch that has been operated off is output. To do. The on-detection signal and the off-detection signal are input to the display control unit 38, and the display control unit 38 reads the stored zone and timbre from the assignment storage unit 36 in response to the on-detection signal to the LCD 17 to display the zone. . Further, the display control unit 38 stops the zone display by the LCD 17 in response to the ON detection signal.

  Thereby, while the switch of the keyboard conductor 11 is turned on in response to the on operation, the zone to which the tone corresponding to the switch is assigned is displayed on the LCD 17.

  FIG. 18 is a block diagram showing the main function of zone display by the switch processing B, where the same reference numerals as those in FIG. 1 denote the same or equivalent parts. The switch-on detection unit 39 outputs an “on detection signal” when it detects that the switches 11 a to 11 p of the keyboard conductor 11 as the sound generation setting switch are turned on. The on detection signal is input to the timer 40 and the display control unit 41, and the display control unit 38 reads the stored zone and timbre from the assignment storage unit 36 in response to the on detection signal to the LCD 17 for display of the zone. Further, the display control unit 41 stops the zone display by the LCD 17 in response to the time TL set in the timer 40 (timer Tz) being ended (time-up).

  Thus, when the keyboard conductor 11 switch is turned on, the zone to which the tone corresponding to the switch is assigned is displayed on the LCD 17 until the timer 40 expires regardless of whether the switch is turned off. Is displayed.

  FIG. 19 is a block diagram showing the main function of zone display by the switch process C. The same reference numerals as those in FIG. 1 indicate the same or equivalent parts. The on detection signal output from the switch on detection unit 39 is input to the timer 42, and the off detection signal is input to the display control unit 43. The timer 42 is activated in response to the ON signal, and when the set time has elapsed, in response to the end of the time-up, the stored zone and timbre are read from the allocation storage unit 36 on the LCD 17 and displayed in the zone. . Further, the display control unit 38 stops the zone display by the LCD 17 in response to the off detection signal. When the on detection signal disappears, the timer 42 stops timing and is reset.

  Thereby, only when the switch of the keyboard conductor 11 is continuously turned on for the time set in the timer 42, the zone to which the tone corresponding to the switch is assigned is displayed on the LCD 17, and the switch is turned off. Until it is done, the zone display is continued.

  According to the above-described embodiment, by simply operating the switch of the keyboard conductor 11 during the performance, the zone that can be generated with the tone assigned to the switch is displayed according to the operation state of the switch. The performer can perform the performance while confirming the zone as required by a simple operation.

  In addition, this invention is not limited to this embodiment, It can change and apply. For example, the upper and lower limits of the zone may be entered by actually pressing the keys of the keyboards 2 and 3 instead of using the increment dial 12.

  In addition, when the zone display is performed by the display elements (LEDs 20 and 21) arranged on the keyboards 2 and 3, the display may be performed in different colors according to the timbre series (that is, the switches 11a to 11p).
