Description

  The present invention relates to an electronic musical instrument locking device, and more particularly, to an electronic musical instrument that can prevent a panel switch or a wheel for setting various parameters from being erroneously operated to generate a musical sound that is not intended by a player. It relates to a locking device.

  There is an electronic musical instrument of the genre called a stage piano that is used for stage performances or used for live performances. This electronic instrument has a panel switch for setting various parameters, a wheel for controlling pitch and modulation, and an expression pedal (Expression Pedal) and foot switch (Foot Switch) for controlling the expression with your foot. ) Etc. are provided.

  In an electronic musical instrument, it is preferable to provide a panel switch, a wheel, an expression pedal, a foot switch, and other controls for setting various parameters as described above in order to perform an expression that is rich in expression and effective. .

  Patent Document 1 proposes that the parameters of the effect should not be changed as the player does not want to change the timbre in the electronic musical instrument. Now, while the effect setting information is set by the resist data, this effect setting information is prioritized over the effect setting information selected by the tone selection switch, so that the resist data is expanded and set by the effect setting information. The effect that has been changed is prevented from being changed by changing the tone.

An electronic musical instrument is also proposed in Patent Document 2 in which a part of the electronic musical instrument is disabled as necessary and control based on preset information is enabled so that a beginner can easily perform.
JP 2003-44049 A Japanese Examined Patent Publication No. 62-7559

  Although it is preferable to have controls such as panel switches, wheels, expression pedals, and foot switches for setting various parameters in an electronic musical instrument, it is preferable for effective performance, but on the other hand it is negative. There is also. For example, in live performances, the performer often performs in intense movements, touching the controls such as panel switches and wheels, and changing the tone to an unintended tone, or adjusting the balance May change. When the tone is set to piano, the performance is usually performed without applying vibrato, but if the performer touches the modulation wheel by mistake, vibrato is added.

  As proposed in Patent Documents 1 and 2, simply disabling some functions of the electronic musical instrument, select and use the functions of the controls such as panel switches, wheels, expression pedals, and foot switches as appropriate. However, it is not possible to eliminate erroneous operation of the operator that is desired to be fixed during performance.

  An object of the present invention is to solve the above-mentioned problems, and to easily invalidate an operator to be invalidated among operators such as switches and wheels for setting various parameters in an electronic musical instrument. An object of the present invention is to provide an electronic musical instrument lock device capable of preventing unintended musical sounds from being generated while appropriately selecting and utilizing functions.

In order to achieve the above object, the present invention provides a locking device for an electronic musical instrument having at least two operation units of a panel switch, a wheel, an expression pedal, and a foot switch, and the panel switch, wheel, expression pedal, and foot. A setting means for individually setting at least two operation units of the switches as a lock range, a registration switch and a registration registration unit, and a lock switch for setting and releasing the lock, set the locking range by means, the locking set preferences and unlock the switch, also the lock information for locking separately each operation unit that is configured as a lock range by the setting unit registration switch Each of By response registered in the registration registration unit, when said registration switch is operated, there is a first feature that locks the operation unit corresponding calls the lock information from the corresponding registration registration unit.

  A second feature is that the parameter for the locked operation unit is fixed to the parameter corresponding to the operation state of the operation unit at the time when the locked operation unit is set.

  In addition, there is a third feature in that, when an operation unit that is provided with a display unit and is locked is operated, the display unit displays that the operation unit is in a locked state.

According to the first feature of the present invention, the plurality of lock types can be set independently, so that a musical tone not intended by the performer is not generated while appropriately selecting and utilizing the function of the operator. Can be. The lock can be set by a simple operation called a registration call operation.

  Further, according to the second feature, it is possible to easily switch between a performance in which the parameter is an arbitrary fixed value and a performance in which the parameter can be changed.

  Further, according to the third feature, it is possible to easily recognize whether the operation invalidity of the operation element is due to lock-on or due to a device malfunction.

  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 to which the present invention is applied. 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. This operation panel 3 is a zone on / off for enabling / disabling (on / off) the sound key range setting on the wheel (for pitch bend control, modulation control) 3-1, main volume 3-2, and keyboard 5. Switch 3-3, zone select switch 3-4 for enabling setting of the sounding key range, volume balance adjusting volume 3-5 for adjusting the sound volume in the sounding key range, internal output (INT) and external output (EXT) LED for display 3-6. The zone on / off switch 3-3, the zone select switch 3-4, the volume balance adjusting volume 3-5, and the internal output (INT) and external output (EXT) display LEDs 3-6 are arranged in four lines here. Thus, the four tone key ranges can be set individually. The zone on / off switch 3-3 and the zone select switch 3-4 have a built-in LED and indicate whether it is currently on or off by turning on or off.

  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.

  For example, when the SW1 of the series 1 in the zone on / off switch 3-3 is turned on, the sounding key range set for the series 1 becomes valid, and the LED built in the SW1 lights up to notify that effect. In addition, the tone color currently set for the series 1 is displayed on the LCD 3-12. Here, if the zone select switch SW1 ′ of the series 1 is pressed and turned on for a short time, the tone color currently set for the series 1 is displayed on the LED 3-12, and if it is held down for a long time, it is set for the series 1. The pronunciation key range (zone) is displayed on the LCD 3-12. If the two keys of the keyboard 5 are sequentially pressed while pressing SW1 ', the key range between the two keys is set as a new tone key range.

  When the sounding key range is the entire key range of the keyboard 5, the LED built in SW1 is lit in red, and when it is a partial key range, the LED is lit in green. As a result, when the SW1 is pressed, it can be recognized 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, even when the LED built in SW1 is off and the setting of sequence 1 is invalid, by turning on SW1 ′, the tone key range currently set for sequence 1 can be confirmed on LCD 3-12. You can also change that. The same applies to other zones 2 to 4 of the zone on / off switches SW2 to SW4.

  Here, if the entire keyboard range is divided into, for example, series 1 and 2 and different timbres are assigned, performance in split mode can be performed by turning on both SW1 and SW2. Also, if overlapping sound key ranges are set in SW1 and SW2, both the SW1 and SW2 are turned on, so that it is possible to perform in dual mode using the overlapping keys.

  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, zone on / off switch processing (S37), zone select switch processing (S38), and other panel switch processing (S39) are sequentially executed.

  In the zone on / off switch process (S37) and the zone 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 that there is no key switch event in S55 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 the lock function on / off and assignment change processing (S32). First, it is determined whether or not there is an ON event of the lock switch 3-8 (S58). If it is determined that the lock switch 3-8 is not present, the process is terminated. If it is determined, it is determined whether or not the lock is currently OFF (S59). ). Here, if it is determined that the lock is not currently turned on, that is, it is turned on, the lock on is changed to the lock off (S60), and then this 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 zone on / off switch process (S37). First, the presence / absence of an on event of the zone on / off switch 3-3 is determined (S65). If it is determined that there is an on event, the LED in the zone select switch 3-4 of the group with the on event is turned on, and others The LED incorporated in the zone select switch 3-4 of the series is turned off (S66). Next, the number (No....) Of the on-event series and its tone name are displayed on the LCD 3-12 (S67), and the LED built in the zone 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 area of the keyboard 5, and is lit in green when the area is a partial area.

  If it is determined in S65 that there is no on event, it is determined whether or not there is an off event of the zone 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, it is determined whether at least one LED in the other zone on / off switch 3-3 is lit. 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 zone select switch 3 of the sequence is selected. -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, it is possible to set the sound key range of a certain series in accordance with the on event of a zone on / off switch 3-3 of the certain series, and the sound key ranges of other series that are on according to the off event. Rather than making the setting possible, it is possible to improve the operability when setting the sound key range. In addition, it is predicted that a sequence having a small sequence number among the sequences being turned on is selected according to an off event of the zone on / off switch 3-3 because a sequence having a small number is normally used. This is because it is possible to appropriately set in what form the series is changed.

  FIG. 7 is a flowchart showing the zone select switch process (S38). First, it is determined whether or not there is an on-event of the zone select switch 3-4 (S73). If it is determined that there is an on-event, the LED in the zone select switch 3-4 with the on-event is turned on. The LED in the affiliated zone 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 zone select switch 3-4 in which the LED is lit can be changed by the tone color setting switch 3-14, and the tone key range is set by pressing and holding the zone select switch 3-4. It can also be changed.

When it is determined in S73 that there is no on event and after the processing in S75, it is determined whether or not the zone 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 in the zone 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 the sound is not on, the process is terminated. If it is determined that the sound is on, the zone on / off switch 3-3 is set according to whether the sound generation range set here is the entire area or a partial area of the keyboard 5. The built-in LED is lit in red or green (S79).
In the present invention, the lock type is registered as a registration. After setting the lock type as described above, the registration type is registered as a registration by pressing the registration selection switch 3-15 of the registration selection and calling switch 3-15 and then pressing the registration registration switch 3-16. be able to. Accordingly, for example, the panel lock type, the wheel lock type, the expression pedal lock type, and the foot switch lock type can be registered as registration for each of the registration selection switches 1, 2, 3, and 4. Then, by operating the registration selection / calling switch 3-15, the registered lock type can be called and set.

  Although the embodiment has been described above, the present invention is not limited to this and can be variously modified. For example, the lock switch 3-8 can be used for settings other than the lock setting. After pressing the lock switch 3-8, the menu display up / down switch (MENU) 3-11 is operated to sequentially display other setting screens. Here, the parameter value selection up / down switch (VALUE This can be realized by performing a parameter value selection operation in step 3-13.
