Description

  The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument that can easily set parameters for a keyboard and has improved operability.

  For electronic musical instruments such as electronic pianos, in addition to the normal mode in which a single tone is assigned to the entire keyboard range, the keyboard is divided into multiple key ranges, each with a bass on the left hand and a melody on the right hand. Some have a split mode in which musical tones are output by assigning them to different timbres, and a dual mode in which a plurality of timbres are assigned to one key and the musical tones of those timbres are simultaneously output when the key is pressed.

  When performing using such an electronic musical instrument, the performer sets the tone key range and tone color in advance, and can perform the selection in normal mode, split mode, or dual mode by performing these selection operations. . At this time, the mode is displayed on an indicator such as an LED.

  Patent Document 1 describes an electronic musical instrument that enables switching between normal performance and split performance by short-time operation of an operator, and enables timbre confirmation by long-time operation of the operator.

  In Patent Document 2, a keyboard dividing point is set by a first key pressing operation, and then the first key pressing position is set in advance to the key range corresponding to the second key pressing position by a second key pressing operation. An electronic musical instrument is described in which a selected timbre is assigned, and keyboard division points can be set and timbres can be exchanged between keyboard ranges.

  An electronic musical instrument that can be played with various keyboard parameters can be played quickly and easily, and the current settings can be easily recognized. It is desirable to obtain.

  Conventionally, in electronic musical instruments, the current mode is displayed with an indicator such as an LED, but when the keyboard's sounding range is set to the full range, it is partly set. But the LED lights up. For this reason, the performer cannot distinguish between the two by simply looking at the LED, and can recognize it only after actually pressing the key, or recalls the setting state in advance and displays it on a display unit such as an LCD. It was possible to recognize it by performing the same operation as when setting the pronunciation key range.

  In order to set multiple tone ranges and timbres in advance and enable them to play in split mode or dual mode, set each tone range and tone in each of the multiple sequences. An on / off switch that can enable / disable the setting for each series is provided, and a select switch for setting the tone key range and tone color corresponding to each on / off switch is considered. In such a case, it is desired that the operability of setting such as a tone key range and tone color is good and that an operation with no sense of incongruity is possible with a limited operation panel configuration.

  In view of the above-described problems, an object of the present invention is to provide an electronic musical instrument that can easily set parameters for a keyboard and has improved operability.

  In order to achieve the above-described object, the present invention provides an electronic musical instrument that has a plurality of sequences, each of which has a parameter for a musical tone keyboard sounded for each of the sequences and performs sound generation based on the parameter. Instructing means for instructing whether or not each of them can be sounded individually, display means for corresponding to the instructing means and displaying whether or not the series is instructed to be soundable, and parameters for each series A setting operation unit for setting, and the display means has a different display form depending on whether the parameter enables sound generation of the entire keyboard range or a part of the keyboard range. The point has the first feature.

  Further, according to the present invention, the different display forms of the display means are the first display color when the parameter enables sound generation of the entire keyboard range, and the sound of a part of the key range can be generated. In this case, the second characteristic is that the second display color is different from the first display color.

  In the present invention, when it is instructed that the sound can be generated by the instruction means, it is possible to set parameters for the keyboard such as a sound key range and a tone color in the sequence, thereby setting various parameters in the sequence. Operability can be improved. In addition, it can be easily recognized from the display form of the display means whether the parameters set for each series enable the sound of the entire keyboard range or a part of the keyboard range.

It is a block diagram which shows one Embodiment of the electronic musical instrument to which this invention was applied. It is a front view which shows the external appearance structure of an operation panel. It is a flowchart which shows an example of the main routine in MPU. FIG. 4 is a continuation of the flowchart of FIG. 3. It is a flowchart which shows on / off of a lock function, and an allocation change process. It is a flowchart which shows an on / off switch process. It is a flowchart which shows a selection switch process. It is explanatory drawing of operation | movement when an ON / OFF switch is turned ON. It is explanatory drawing of operation | movement when an ON / OFF switch is turned ON.

  The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an electronic musical instrument according to the present invention. In the figure, an MPU 1 includes a ROM and a RAM, and controls the entire electronic musical instrument according to a control program stored in the ROM. In addition to the control program, the ROM stores various parameters for setting the performance state, such as a plurality of tone color parameters and effect parameters. The RAM is used as a work area for the MPU 1 and is also used as a buffer for temporarily storing data of various registers. This RAM may be backed up by a battery, for example.

  In addition to the timer interrupt circuit, the MPU 1 also has a serial port for connection to MIDI interfaces (MIDIin, MIDIout) 2-1, 2-2. The MIDI interfaces 2-1 and 2-2 are signal transmission / reception circuits that exchange MIDI messages with external MIDI devices.

  The operation panel 3 has various panel switches for setting a state during performance, and has an appearance configuration as described later. A panel interface (I / F) 4 scans the operation panel 3 to generate switch event information indicating ON / OFF of the panel switch, and a display such as an LCD (hereinafter referred to as LCD) disposed on the operation panel 3. To display various setting information from the MPU 1. The switch event information is stored in the RAM of the MPU 1 in association with each panel switch.

  The keyboard (keyboard) 5 has a plurality of keys (keys), and includes, for example, two sensors for detecting key event information indicating ON / OFF of each key and touch information indicating key pressing strength, that is, velocity. Have. The keyboard I / F 6 scans the sensor and generates key event information and touch information based on the state. Such information is stored in the RAM of the MPU 1 in association with the key number.

  Event information generated by the operation of the expression pedal 7 is converted into digital information by the A / D converter 8 and then stored in the RAM of the MPU 1. On / off event information by the operation of the foot switch 9 is also stored in the RAM of the MPU 1.

  The event information stored in the RAM is input to the tone generator 10 as appropriate. The tone generator 10 is a circuit for generating a musical tone signal based on event information by a waveform readout method. From the waveform memory in which digital musical tone waveform sample values are stored, the tone generator 10 sequentially generates waveforms at an address interval proportional to the pitch to be generated. Data is read out, and an interpolating operation is performed to generate a musical sound waveform signal. The tone generator 10 has an envelope generating circuit, multiplies the musical tone waveform signal by an envelope signal generated based on the set envelope parameter, adds an envelope, and outputs a musical tone signal. The tone generator 10 has a plurality of, for example, 32 tone generation channels. Actually, however, a plurality of tone signals can be independently generated simultaneously by operating one tone generator in a time-division multiplexing manner. It is configured.

  The effector 11 includes a DSP (Digital Signal Processor), and can apply various effects such as reverb and echo to the musical sound generated by the tone generator 10 according to the operation of the operation panel 3.

  The D / A converter 12 converts a digital musical tone signal into an analog signal, and this analog signal is given to the sound system 13 to output a musical tone.

  FIG. 2 is a front view showing an external configuration of the operation panel 3. The operation panel 3 enables / disables (on / off) the setting of parameters such as the tone range and tone of the wheel (for pitch bend control and modulation control) 3-1, main volume 3-2, and keyboard 5. ON / OFF switch 3-3, select switch 3-4 for instructing that parameters such as a tone key range and tone color can be set alternatively, volume balance adjusting volume 3-5, internal output (INT) And an external output (EXT) display LED 3-6. The on / off switch 3-3 corresponds to the instruction means of the present invention.

  On / off switch 3-3, select switch 3-4, volume balance adjustment volume 3-5, and internal output (INT) and external output (EXT) display LEDs 3-6 are arranged for four lines here. Thus, parameters such as the four tone key ranges and timbres can be individually set. If this is divided into two lines, it is possible to perform in the split mode or dual mode, and if it is over three lines, it is possible to perform with further timbres superimposed. The on / off switch 3-3 and the select switch 3-4 have a built-in LED and indicate whether it is currently on or off by turning on or off. The LED with the built-in on / off switch 3-3 corresponds to the display means of the present invention.

  The operation panel 3 further includes an effect, equalizer, tone modify, MIDI CC (Control Change) parameter setting switch group 3-7, lock switch 3-8, effect on / off switch 3-9, and reverb on / off switch 3. -10, menu display up / down switch (MENU) 3-11, LCD 3-12, parameter value selection up / down switch (VALUE) 3-13, tone color setting switch 3-14, registration selection and calling switch 3-15 and a resist registration switch 3-16. The LCD 3-12 can display 2 × 16 characters, for example.

  In an electronic musical instrument, the standard state of the simplest mode, that is, the standard state of the normal mode is usually set in the initial state such as when the power is turned on. Different settings and performance modes can be set. The menu, operation instructions, and setting state at that time are displayed on the LCD 3-12.

  The following describes an example in which the tone key range and tone parameters can be set by operating the on / off switch 3-3 (SW1 to SW4) and the select switch 3-4 (SW1 ′ to SW4 ′). The present invention includes a keyboard capable of setting at least one of parameters for a keyboard such as a tone generation key range and a tone color of each tone generation key range.

  For example, when the SW1 of the series 1 in the on / off switch 3-3 is turned on, the tone key range set for the series 1 becomes valid, and the LED built in the SW1 lights up to notify that effect. This LED has a different display form depending on whether the set tone key range is the entire key range or a part of the keyboard 5. For example, when the sounding key range is the entire key range of the keyboard 5, it is lit in red, and when it is a partial key range, it is lit in green. Thereby, at the stage when SW1 is pressed, it is possible to know whether the tone key range set for the series 1 is the entire key range of the keyboard 5 or a partial key range.

  Further, the tone color currently set for the series 1, for example, “1.AC. Bass” is displayed on the LCD 3-12. When the LED built in SW1 is lit in red or green, it is possible to perform using the tone key range and tone color set for series 1.

  If the select switch SW1 ′ of series 1 is pressed for a long time, for example for a few seconds, and turned on, the tone key range (zone) currently set for series 1 is displayed on the LCD 3-12, and the LED built in SW1 ′ lights up. . For example, the tone key range “1.Key Range (I) A-1> C 7” of the INT section (internal output) is displayed in the upper row of the LCD 3-12, and the tone key range of the EXT section (external output) is displayed in the lower row. “1.Key Range (E) A-1> C7” is displayed. Since the tone generation key range set in this case is the entire key range of the keyboard 5, the LED built in SW1 is lit red.

  Here, in order to change the sound key range set for the series 1, while holding down SW1 ', first, the lowest key of the left hand, for example, "A-1" is pressed. As a result, the display on the LCD 3-12 changes to “1. Key Range (Both) A-1> ---”, and the lowest key of the pronunciation key range is set. Note that “(Both)” represents a sound key range for both the INT section and the EXT section. These can be set separately.

  Next, while pressing SW1 ', the highest key of the left hand, for example, "B2" is pressed. As a result, the display on the LCD 3-12 becomes “1. Key Range (Both) A-1> B2”, and the highest tone of the tone generation key range is set. If the second key depression is lower than the first key depression, the left and right are automatically switched and set. Here, when SW1 'is released, the tone key range "A-1> B2" for system 1 is determined. Since the tone key range set in this case is a partial key range of the keyboard 5, the LED built in SW1 is lit in green.

  If SW1 is pressed again to turn it off, the red or green display is extinguished, and a performance that does not use the tone key or tone set for system 1 is possible.

  Even when SW1 is off, the currently set tone color can be displayed on the LCD 3-12 by pressing SW1 'for a short time, and the tone color can be changed by the tone color setting switch 3-14 in this state. . Further, if SW1 'is pressed and held, the currently set sounding key range can be displayed on the LCD 3-12, and the sounding key range can be changed by performing the same operation as described above in this state.

  The case where the tone key range and tone color are set for the sequence 1 has been described above, but the tone key range and tone color can be set in the same manner for the other sequences 2 to 4 as well. Here, if the entire key range of the keyboard 5 is divided into, for example, series 1 and 2 and different timbres are assigned, performance in the split mode can be performed by turning on both SW1 and SW2. In addition, if overlapping sound key ranges are set for SW1 and SW2, both the SW1 and SW2 are turned on, so that the keys in the overlapped portion can be pressed to perform in dual mode. For example, the right hand pronunciation key range “C 3> C 7” can be set for series 2, and the key range that overlaps the tone key range set in series 1 and 2 for series 3 and 4 is set as the pronunciation key. A different tone can be set.

  In order to facilitate the setting operation of the sound key range, when the on / off switch 3-3 is turned on, it is preferable to turn on the LED incorporated in the select switch 3-4 of that series.

  FIG. 8 is an explanatory diagram of this operation. For example, when the on / off switch SW2 of the series 2 is turned on by pressing the on / off switch SW2 of the series 2 in a state where the on / off switches SW1 and SW3 of the series 1 and 3 are on, the LED inside the SW2 is lit and the Indicates that the setting is valid with series 1 and 3. Along with this, the select switch 3-4 indicates that the LED in the series 2 switch SW2 'is lit and the tone key range and tone color for the series 2 can be set. At this time, the LCD 3-12 displays the timbre currently set for the series 2, for example, “2.Strings”. Here, the tone color can be changed by the tone color setting switch 3-14, and by pressing and holding SW2 ', the tone key range set for the series 2 can be displayed and the setting can be changed. .

  Further, when the on / off switch 3-3 built-in LED is turned off in order to facilitate the sound key range setting operation, the other series of select switches 3-4 built-in accordingly. It is better to turn on the LED.

  FIG. 9 is an explanatory diagram of this operation. When SW2 is pressed again in the state of FIG. 8 to turn it off, the LED built in SW2 is turned off, indicating that the setting is invalid. Along with this, the LED built in SW2 ′ is turned off, and one of the systems 1 and 3 that are currently on, for example, the LED built in SW1 ′ of system 1 is turned on to set the tone key range and tone for system 1. Indicates that it has become possible. Further, the LCD 3-12 displays a tone color currently set for the system 1, for example, “1. Concert Pioano”. The tone color can be changed by the tone color setting switch 3-14, and by pressing and holding SW1 ', the tone key range set for the series 2 can be displayed and the setting can be changed. It should be noted that it is designed as appropriate which of the current on-line systems to be settable as the built-in LED of the on / off switch 3-3 is turned off. Yes.

  Next, lock setting by operating the lock switch 3-8 will be described. The lock switch 3-8 is operated to set / release (ON / OFF) the lock. There are several lock types, such as wheel lock, panel lock, expression pedal lock, and foot switch lock. The wheel lock disables the operation of the wheel 3-1, the panel lock disables the operation of the panel switches 3-3 to 3-11 and 3-13 to 3-16, and the expression pedal lock disables the expression pedal 7. In the foot switch lock, the operation of the foot switch 9 is invalidated. Which type of lock is effective is selected by a parameter value selection up / down switch (VALUE) 3-13.

  When the lock switch 3-8 is operated to lock on, the current lock type is displayed on the LCD 3-12. For example, if the current lock type is panel lock, “Lock Type 1: Panel Lock” is displayed on the LCD 3-12. At this time, if the lock switch 3-8 is operated again to turn off the lock, the panel lock is released.

  The lock type can be changed by the lock switch 3-8 and the parameter value selection up / down switch (VALUE) 3-13. For example, to change from panel lock to wheel lock, call the current lock type “Lock Type 1: Panel Lock” and use the parameter value selection up / down switch (VALUE) 3-13 to set the lock type “Lock Type 2: Wheel Lock”. ”Can be selected. In addition, when changing to expression pedal lock or foot switch lock, “Lock Type 3: Expression Pedal Lock” and “Lock Type 4: Foot Switch Lock” can be selected with the parameter value selection up / down switch (VALUE) 3-13. Just choose.

  It should be noted that it is not limited to one of the above lock types, and it is preferable that a plurality of them can be combined to form a lock range. Thereby, a necessary part can be appropriately selected and locked by a simple operation. How the lock range is determined is also arbitrary. It is also preferable that all the controls other than the keyboard 5 and the main volume 3-2 can be locked.

  When the panel switch of the operation panel 3 is operated in the panel lock state, the LCD 3-12 displays that it is currently in the panel lock state. If necessary, it displays that it is necessary to release the panel lock to enable the operation. Thereby, the performer can easily recognize that the switch operation of the operation panel 3 is not effective due to the panel lock, and can be distinguished from the apparatus malfunction. This can be notified by a display device such as an LED other than the LCD 3-12.

  When the lock is set, the parameter for the locked operation unit can be fixed to the parameter corresponding to the operation state of the operation unit at the time when the operation unit is set to the locked state. For example, in the case of wheel lock, the parameter of the setting state of the wheel 3-1 when the wheel lock is made is set as a fixed value. By doing in this way, it is possible to easily switch between the performance in which the pitch bend and the modulation are arbitrarily fixed values by the on / off of the lock switch 3-8 and the performance in which the performance can be changed.

  Also, in the case of the expression pedal lock, if the lock operation is performed at a position where the expression pedal 7 is located, the performance can be controlled by the performance and the pedal at a fixed volume in the locked state by turning on / off the lock switch 3-8. You can easily switch to playing at the volume you want.

  FIG. 3 and FIG. 4 are flowcharts showing an example of the main routine in the MPU 1, and here, particularly, the lock processing is shown in detail. First, when the power is turned on, the MPU 1 and the LSI constituting the tone generator 10 are initialized (S31). Next, on / off of the lock function and allocation change processing are executed (S32). Details of this processing will be described later. Next, the presence / absence of an on-event of panel switches other than the lock switch 3-8 is determined (S33). If it is determined in S33 that there is an on event, it is determined whether or not the lock is on (S34). If it is determined that the lock is on, it is further determined whether or not the panel lock is on (S35). . If it is determined in S35 that the panel lock is on, the LCD 3-12 displays an interrupt indicating that the panel lock is on for a predetermined time (for example, 1 second), and invalidates the on event determined in S33. (S36). If it is determined in S35 that the panel lock is not on, on / off switch processing (S37), select switch processing (S38), and other panel switch processing (S39) are sequentially executed.

  In the on / off switch process (S37) and the select process (S38), the parameters set for the series 1 to 4 are validated or the parameters are reset. Details of these processes will be described later. The other panel switch processing (S39) is the same as the panel switch processing in the conventional electronic musical instrument.

  When it is determined in S33 that there is no on-event of any panel switch other than the lock switch 3-8, and after the processing of S36 and S39, the presence or absence of an event of the wheel 3-1 is subsequently determined (S40). If it is determined in S40 that there is an event, it is determined whether or not the lock lock is on (S41). If it is determined that the lock is on, it is further determined whether or not the wheel lock is on (S42). ). If it is determined in S42 that the wheel lock is turned on, the fact that the wheel lock is turned on is displayed for a predetermined time on the LCD 3-12, and the event determined in S40 is invalidated (S43). If it is determined in S42 that the wheel lock is not on, wheel processing (S44) is executed.

  When it is determined in S40 that there is no wheel event, and after the processing in S43 and S44, the presence or absence of an expression pedal 7 event is subsequently determined (S45). If it is determined in S45 that there is an event, it is determined whether or not the lock is on (S46), and if it is determined that the lock is on, it is further determined whether or not the expression pedal lock is on ( S47). If it is determined in S47 that the expression pedal lock is ON, the fact that the expression pedal 7 is ON is displayed on the LCD 3-12 for a predetermined time, and the event determined in S45 is invalidated (S48). . If it is determined in S47 that the expression pedal lock is not on, an expression process (S49) is executed.

  When it is determined in S45 that there is no event of the expression pedal 7, and after the processing of S48 and S49, the presence or absence of an event of the foot switch 9 is subsequently determined (S50). If it is determined in S50 that there is an event, it is determined whether or not the lock is on (S51). If it is determined that the lock is on, it is further determined whether or not the foot switch lock is on (S52). ). If it is determined in S52 that the foot switch lock is on, the LCD 3-12 displays that the foot switch 9 is on for a predetermined time and invalidates the event determined in S50 (S53). If it is determined in S52 that the foot switch lock is not on, a foot switch process (S54) is executed.

When it is determined in S50 that there is no event of the foot switch 9, and after the processing of S53 and S54, it is determined whether or not there is a key switch event of the keyboard 5 (S55). If it is determined in S55 that there is a key switch event, the internal output / external output (INT / EXT) and sound generation range are checked for each series, and sound generation processing and MIDI OUT processing are executed according to the check result (S56). When it is determined in S55 that there is no key switch event and after the process of S56, each volume process of the operation panel 3 is executed (S57), and the process returns to S32.
FIG. 5 is a flowchart showing lock function on / off and assignment change processing (S32). First, the presence / absence of an on event of the lock switch 3-8 is determined (S58). If it is determined that there is no event, the process is exited. ). If it is determined that the lock is not currently turned on, that is, it is turned on, the lock-on is changed to lock-off (S60), and the process is exited. At this time, the LED built in the lock switch 3-8 is turned off.

  If it is determined in S59 that the current lock is off, the lock is turned on (S61) and the current lock type is displayed on the LCD 3-12 (S62). Next, the presence / absence of an on event of the parameter value selection up / down switch (VALUE) 3-13 is determined (S63). If it is determined that there is no on event, this process is terminated. The lock type is changed in accordance with the event, stored, and displayed on the LCD 3-12 (S64). Then, this process is exited.

  FIG. 6 is a flowchart showing the on / off switch process (S37). First, the presence / absence of an on event of the on / off switch 3-3 is determined (S65). If it is determined that there is an on event, the LEDs included in the select switch 3-4 with the on event are turned on. The LED in the series select switch 3-4 is turned off (S66). Next, the number (No....) Of the on-event series and the tone name thereof are displayed on the LCD 3-12 (S67), and the LED built in the on / off switch 3-3 of the on-event series is turned on (S68). ). Here, the LED is lit in red when the sound generation range is the entire key range of the keyboard 5, and is lit in green when the key range is partial.

  If it is determined in S65 that there is no on event, it is determined whether there is an off event of the on / off switch 3-3 (S69). If it is determined that there is no off event, the process is terminated. If it is determined that there is an off event, whether or not the LED incorporated in at least one on / off switch 3-3 of another series is lit, that is, other It is determined whether the line is on (S70). If it is determined in S70 that the other sequence is not on, the process is terminated. If it is determined that the sequence is on, a sequence having a small sequence number is selected from the on-sequences, and the select switch 3- 4 The built-in LED is turned on (S71), and the sequence number and its tone color name are displayed on the LCD 3-12 (S72).

  As described above, the on / off switch 3-3 of a certain series automatically turns on the select switch 3-4 of that series, and the other is in the on state according to the off event. The operability of setting various parameters including the sound key range can be improved by automatically changing the select switch 3-4 in the series to the on state. In addition, it is predicted that a sequence having a small sequence number among the sequences being turned on is selected in accordance with an off event of the on / off switch 3-3. This is because it is possible to appropriately set in what form the series is changed.

  FIG. 7 is a flowchart showing the select switch process (S38). First, it is determined whether or not there is an on event of the select switch 3-4 (S73). If it is determined that there is an on event, the LEDs in the select switch 3-4 of the group having the on event are lit, The LED built in the select switch 3-4 is turned off (S74). Next, the number of the on-event series (No....) And its tone color name are displayed on the LCD 3-12 (S75). Here, the tone color of the select switch 3-4 whose LED is lit can be changed by the tone color setting switch 3-14, and the tone key range is changed by long pressing the select switch 3-4. You can also

  If it is determined in S73 that there is no on event, and after the processing in S75, it is determined whether or not the select switch 3-4 is on (S76). If it is determined that it is not turned on, the process is exited. If it is determined that it is turned on, the sound generation range of the series is set based on the key pressed during the turn-on. At this time, the LCD 3-12 displays the newly set sounding range (S77). Next, it is determined whether or not the LED incorporated in the on / off switch 3-3 of that series is lit, that is, whether or not the series is on (S78). If it is determined in S78 that it is not on, this process is terminated. If it is determined that it is on, an on / off switch is set according to whether the tone key range set here is the entire key range or a partial key range of the keyboard 5. 3-3 The built-in LED is lit in red or green (S79).

  In the above, the switch function and its status display function are realized by the LED built-in switch, such as the on / off switch and the built-in LED, and the select switch and the built-in LED, but the present invention is not limited to this. For example, it can be realized by a plurality of on / off switches and their corresponding LEDs, and a large LCD that collectively displays a plurality of select switches and their corresponding LEDs, and a touch panel disposed on the LCD surface.
