DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic music apparatus capable of performing various kinds of music control in accordance with a moving mode by moving a hand or the like in a space.
The electronic music device according to the present invention can be used, for example, for performing music control in an electronic musical instrument or the like. Here, the electronic music device of the present invention is an electronic musical instrument, a musical sound generating device, a musical sound changing device, or a control device thereof, such as a synthesizer, keyboard, drum machine, effect processor, effect pedal, sequencer, sound source module, Is included.

2. Description of the Related Art Conventionally, a non-contact electronic music apparatus which optically detects a movement of a hand or the like in a predetermined space and gives an operation instruction is known. This device has one light source (such as an infrared light emitting diode) that irradiates light into the space, and one light receiving element (infrared light) that receives light from the light source reflected by the hand when the hand enters the space. Sensors) are provided as a pair, and when the reflected light from the hand is received by the light receiver, when the amount of received light exceeds a certain threshold, a predetermined operation instruction is turned ON, and the light is received below the threshold. O if
This is a switch-like control to make the FF.

[0003]

In the above-mentioned conventional non-contact type electronic music apparatus, the intensity distribution of the light beam emitted from the light source is as shown in FIG. 26, for example. in this case,
The amount of light received by the light receiver differs between the case where the hand is held directly above the light source and the case where the hand is placed on the side, even at the same height. Therefore, when an on / off operation instruction is to be issued based on whether or not the amount of received light exceeds a predetermined threshold value, an erroneous operation may be caused if the operation instruction is simply issued using only the height of the hand as a guide. It is highly possible that That is, this type of conventional electronic music apparatus has a problem that it is difficult for an operator to recognize how much hand is brought close to the sensor before the switch is turned on or off, and thus it is not possible to stably give a music control operation instruction. There is a point. Also, as the content of the operation instruction, only binary control of whether or not to perform a certain music control, that is, ON or OFF for a predetermined process can be performed.

[0004] The present invention has been made in view of the above-described problems, and it is possible to reliably perform desired music control by moving an object in an operation space. It is an object of the present invention to be able to control music of various contents by making various changes.

[0005]

According to a first aspect of the present invention, there is provided an electronic music apparatus for outputting music and moving the music in a predetermined operation space. An electronic music device for issuing a music control instruction according to a movement mode of an object, comprising: one or more light sources for irradiating the operation space with light; and one or more light sources for receiving light reflected by an object in the operation space. And an optical sensor disposed so as to have at least two light paths from the light source through the object to the optical sensor, and output detection values corresponding to the amounts of light received through the respective paths. The optical means, the signal generating means for generating music, and the control of the music generated by the signal generating means when the mutual relation between the current values of the detected values of the respective paths becomes a predetermined relation. Music control means for performing the following. In this electronic music device, based on the detection values of the reflected light from the object that has passed through at least two paths, the correlation between the detection values of the respective paths has a predetermined relationship, for example, when the values have become the same value. Since the music control instruction is issued, the position of the object in which the music control instruction is generated in the operation space is relatively uniquely determined as compared with the conventional case in which one light source and one light sensor are used. This makes it easy for the operator to accurately grasp the timing at which the music control instruction is generated according to the moving operation of the object.

For example, this optical means is composed of two light sources arranged on a straight line and one optical sensor arranged at the center of the two light sources. If light from each light source is received in a time-division manner, two types of detection values are obtained, and the position where these detection values are the same value is generally considered to be immediately above the optical sensor. Thus, the operator can accurately grasp the timing at which the music control instruction is issued as the object moves. Note that the “predetermined relationship” is not limited to “when the detected values of the respective routes have the same value” as described above. For example, “the difference between the detected values of the respective routes is within a predetermined range” When
Alternatively, it may be “when the ratio of the detection values of the respective routes has reached a predetermined value”. The light of the light source described above may be not only ordinary visible light but also infrared light or ultraviolet light.

In the case where the electronic music apparatus according to the present invention is applied to, for example, an electronic musical instrument, the above-mentioned music control instructions include the control of an automatic performance apparatus, the control of a sound source, and the provision of an effect. This refers to control including control of the device (effector). In this case, the following control is specifically targeted. Automatic performance device: playback instruction of performance information, stop instruction, loop playback instruction, mute instruction, volume instruction, panpot instruction, switching of performance information, etc. Sound source: tone group switching instruction, tone number switching instruction, tone waveform switching instruction , Filter cutoff and resonance instructions, LFO depth and rate instructions,
Envelope instructions, etc. Effect giving device: ON / OFF instruction for effect, instruction for switching effect type, etc.

A peak value detecting means for detecting the peak value, a signal generating means for generating music, and controlling the music generated by the signal generating means in response to the detection of the peak value by the peak value detecting means. Music control means. For example, if an object is approached from the upper side toward the optical sensor and inverted at a desired height, and this time the object is moved away, a clear peak value will occur in the detection value, and based on this peak value, If the music control instruction is issued, the operator can accurately generate the peak value, and thus can accurately issue the music control instruction. In addition, the judgment that the peak value was detected,
The present detection value may be compared with the maximum value of the detection values, and the current detection value may be lower than the maximum value, or the current detection value may be lower than the maximum value by a predetermined value. You may. The peak value detecting means may detect a peak value of the detection value detected after the detection value detected by the optical means becomes smaller than a predetermined value.

Selecting means for selecting any music control mode. With this configuration, the maximum value of the detection value of each path for the movement of the object is:
Since various patterns are taken according to the movement mode of the object, the content of the operation instruction can be changed according to the movement mode, and therefore, the content of the operation instruction can be enriched. For example, the optical means is composed of two light sources arranged in a straight line on the left and right and one optical sensor arranged in the center position, and each light source generates light alternately with time, and each light source If light from the object is received in a time-sharing manner, two types of detection values can be obtained. In this configuration, the object moves from right to left and comes above the optical sensor, and the object moves from left to right. Since the maximum value of the detected value of each path is different from the case where it comes above the optical sensor, the music control instruction having different contents can be selected according to each of the movement modes. In this case, for example, when the detected values of the respective routes become the same, by observing the magnitude relationship of the maximum values of the detected values of the stored and updated routes, it is possible to determine in which direction the object is to be moved. Detection is performed, and different control is performed according to the operation direction (right to left or left to right). Note that the maximum value detecting means may detect the maximum value of the detection value detected after the detection detected by the optical means becomes smaller than a predetermined value.

And a selection means for selecting a music control mode corresponding to a range to which the peak value belongs in accordance with the peak value detected by the peak value detection means. For example, if the object is approached from the upper side toward the optical sensor, the object is inverted at a desired height, and the object is moved away this time, a clear peak value will be generated in the detection value, and based on this peak value, If the content of the music control instruction is changed, the content of the music control instruction can be variously set according to the height position at which the object is reversed from the approaching state to the distant state. Therefore, if the content of the music control instruction is changed according to the range of the peak value (that is, according to the height of the movement of the object), the content of the music control instruction performed according to the movement mode of the object can be further enriched. it can. Further, in this device, the operator recognizes at which height position the inversion is to be performed, so that a peak value corresponding to each position can be accurately generated, and therefore, a music control instruction having desired contents can be provided. Can be selected accurately. As described above, the determination that the peak value has been detected may be made by comparing the current detection value with the maximum value of the detection values, and when the current detection value falls below the maximum value. May be lower than the maximum value by a predetermined value.

The operation of this embodiment will now be described.
In this embodiment, various operation instructions can be given by moving the object up, down, left and right in the operation space above the beam controller provided on the panel. This operation instruction is, whether the object was moved from right to left as seen from the front of the panel, or moved from left to right, how high was the object viewed from the panel surface at that time,
The content of the operation instruction can be changed in accordance with the situation.

Light emitting diode 1 of beam controller
A and 1B are provided so that the beam irradiation directions are inclined outward, respectively. For example, when an object (for example, a hand) is moved in the direction of the arrow in FIG. 5 (from left to right), The detection values RA and RB of the light emitting diodes 1A and 1B have characteristics as shown in FIG. In FIG. 6, the horizontal axis represents the position of the object in the horizontal direction as viewed from the front of the beam controller (the front of the panel), and the vertical axis represents the values of the detection values RA and RB. First, the characteristics with respect to the infrared beam from the light emitting diode 1A will be described. As the object enters the operation space from the left side, the object approaches the light emitting diode 1A and the reflected light to the infrared sensor 2 increases. The value RA gradually increases, and eventually reaches a peak value RApeak (the top portion in the characteristic) corresponding to the height of the object at a position near the light emitting diode 1A, and thereafter, the object moves away from the light emitting diode 1A. Gradually decreases, resulting in a mountain shape as shown in the figure. Similarly, the characteristic with respect to the infrared beam from the light emitting diode 1B also has a peak shape with the peak value being RBpeak, but is different in that the position where the detected value RB has the peak value is near the light emitting diode 1B. It can be easily understood that similar characteristics can be obtained when the object is moved from right to left so as to enter the operation space.

As can be seen from the characteristics shown in FIG. 6, the position where the two detected values RA and RB have the same value at the same time is near the position directly above the infrared sensor 2 and at what height on the panel at that time. Detection values RA and RB depending on whether the object has been moved
(Absolute value) changes. Further, the detection value RA
It can be determined whether the object has been moved from right to left or from left to right, depending on which side of RB and RB has the peak value first. In the present embodiment, the content of the operation instruction is switched according to the movement mode of these objects, and the content of the operation instruction is also switched for each mode.

This mode is selected by pressing the MODE button 65
Carried out by pressing one of ₁ to 65 _7. 13 to 19
Shows specific display screens corresponding to the modes 1 to 7, respectively. This display screen is displayed on the display 66 on the panel. The details of the operation instruction in each mode will be described later. Here, an example of a typical format of the display screen will be described with reference to the display screen of mode 1 shown in FIG. The details of modes 1 to 7 shown in FIGS. 13 to 19 will be described later. In FIG. 13, the display screen shows detection values RA corresponding to the light emitting diodes 1A and 1B,
The RBs are displayed in the form of “L: ○” and “R: xx”, respectively, and the number of the current mode is indicated by the form “MODE = △”. Also, below “L → R”, corresponding to the case where the object is moved from left to right, the content of the operation instruction given to a predetermined target device (for example, a sequencer, a sound source or an effector) is shown. , “L ← R” indicate the contents of operation instructions to be performed in response to the movement from right to left. The contents of the operation instruction include, for example, “L → R”, a performance stop instruction to the sequencer, and “L ← R”.
R "indicates an instruction to start playback of a phrase. "VERT
In the column of “ICAL”, the control target (phrase number in the example of FIG. 13) of the operation instruction selected according to each height range of the hand in the vertical direction is displayed, and the range of the detection value corresponding to each height range is displayed. Is displayed in the column of “VALUE”. The closer the detection value is to "99", the lower the height is when viewed from the panel surface.
The closer to "0", the higher the height "

The operation of this embodiment will now be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. Here, FIG.
FIG. 9 is a flowchart of the main routine. FIG.
0 and FIG. 11 show a timer interrupt routine.
Is executed every 5 ms interrupt from the CPU 3 to the CPU 3. FIG. 12 is a flowchart of a process related to a light emitting diode.

First, the timer interrupt processing routine shown in FIGS. 10 and 11 will be described. This timer interrupt routine is based on a detection value R corresponding to the light emitting diodes 1A and 1B.
A and RB are sequentially detected, and based on these detected values,
The processing of updating the maximum values Amax and Bmax of the detected values, the ON / OFF processing of the LR trigger flag and the RL trigger flag, and the ON / OFF processing of the maximum value write permission flag are performed.

When the timer interrupt processing routine is started, first, processing relating to the light emitting diode 1A is performed (step S21). FIG. 12 shows a flowchart of this process. The light emitting diode 1A emits light (step S41), and the current detection value RA detected by the infrared sensor 2 is obtained.
(Ie, the detected value of the light emitting diode 1A according to the reflected light from the object) is stored in the A register as the current value A (step S42), and the light emitting diode 1A is turned off (step S43). When the processing related to the light emitting diode 1A is completed, next, the same processing related to the light emitting diode 1B is performed (step S22). As a result, the light emission timing of the light emitting diodes 1A and 1B alternates, and the detection value R from these light emitting diodes 1A and 1B is changed.
A and RB can be obtained in a time sharing manner.

When the current values A and B are obtained, it is next determined whether the maximum value write permission flag is ON or OFF (step S23). If ON, it means that the maximum values Amax and Bmax can be updated. Therefore, first, it is determined whether or not the current value A is equal to or greater than the maximum value Amax (step S24). Then the maximum value Amax
Is replaced by the current value A (step S2).
5) If the current value A is smaller than the maximum value Amax, it is assumed that the maximum value Amax has already reached the peak value and is not updated. Next, it is determined whether or not the current value B is equal to or greater than the maximum value Bmax (step S26). If the current value B is equal to or greater than the maximum value Bmax, the maximum value Bmax is replaced with the current value B to update (step S27). Current value B is maximum value B
If it is smaller than max, the maximum value Bmax is not updated.

Next, it is determined whether or not the two current values A and B are equal (step S28). Two current values A, B
Are equal, it means that the hand is at the middle position between the left and right (in the vicinity of the infrared sensor 2), as can be seen from the characteristic diagram of FIG. In this case, the maximum values Amax and B
The magnitude relationship of max is determined (step S29), and Amax is determined.
If .gtoreq.Bmax, the object moves from left to right and reaches an intermediate position (when Amax> Bmax) or swings up and down near the intermediate position (when Amax = Bmax)
If Amax <Bmax, it can be estimated that the object has moved from right to left. If Amax ≧ Bmax, it is determined whether the current value A is smaller than the maximum value Amax (step S30). This determination is to see whether the current value A is still increasing or has entered a decreasing state, whereby whether or not the current maximum value Amax is the peak value of the characteristic relating to the current value A (the peak of the mountain) is determined. Can be determined. If the current maximum value Amax is the peak value, it can be determined that the object has moved from left to right and has reached the middle position between the left and right.
The trigger flag is set to ON (step S31). On the other hand, if the maximum value Amax is not the peak value, the timer interrupt routine is terminated once so that the maximum value Amax can be further updated from the next time.

If it is determined in step S29 that Amax <Bmax, a similar comparison process is performed between the detected value B and the maximum value Bmax (step S32). If the maximum value Bmax is the peak value, the object moves from right to left. It is determined that it has reached the left and right intermediate position while moving, and the RL trigger flag is set to ON (step S33).

After the LR trigger flag or the RL trigger flag is set to ON, the maximum value write permission flag is turned OFF so that the maximum values Amax and Bmax detected as peak values do not fluctuate (step S34), and the maximum value Ama
x and Bmax are not rewritten. As described later, when the LR trigger flag or the RL trigger flag is turned ON, an instruction to start playing a phrase or the like is triggered, but the current values A and B become large by changing the hand movement immediately after this trigger. In such a case, a new maximum value may be written to the Amax register and the Bmax register. In such a case, when the next operation instruction is performed, “VALUE” is a small phrase (corresponding to the first phrase). ) May be selected as a control target and it may not be possible to trigger. Therefore, after the trigger, the maximum value write permission flag is turned off and the current value A or B once drops below a predetermined value (0). , The maximum value is not updated.

Therefore, when it is determined in step S23 that the maximum value write permission flag is OFF, it is determined that the hand held over the beam controller has passed the middle position between the left and right sides (that is, the trigger has been performed). In this case, when the current value A or B becomes “0” (steps S35 and S36), the hand once goes out of the operation space and the current operation instruction by the hand is completed. In this case, the maximum value write permission flag that has been turned off is turned on again in preparation for the next operation instruction.
N is set (step S37), and the timer interrupt routine ends.

As described above, in this timer interrupt routine, the current values A and B (= detection value RA and detection value RB) are stored in the Amax register and the Bmax register in the RAM 5, respectively.
The maximum value (peak) is stored in the Amax register and the Bmax register. For example, when the object is moved from left to right as shown in FIG.
The value of the register does not change from the position shown in FIG. When the object reaches the intermediate point (directly above the infrared sensor) and the current value A and the current value B become the same value (the position (a) in the figure),
The size of the Amax register and the size of the Bmax register are compared, and the control object corresponding to the larger value at this time (in this case, the peak value of the Amax register) is selected and the process is executed (mode = 1 described later). In this case, a process of “stopping phrase 2”). When execution of the processing is instructed, A
Although the max register and the Bmax register are cleared to "0", writing to the Amax register and the Bmax register is prohibited until the current value A and the current value B become "0".

Next, the main routine shown in FIGS. 8 and 9 will be described. When the power of the embodiment apparatus is turned on,
First, the above-described various registers and flags provided in the RAM 5 are initialized (step S1). Next, it is determined whether or not the beam controller button 61 has been operated (step S2). If the button controller button 61 has been operated, a toggle operation is performed by the operation, and the one that has been off until now has been switched on. For example, the display light emitting diode 611 is turned on, and the timer 10 for giving a timer interrupt is started. On the other hand, what has been ON by this operation
If it has been switched to FF, the display light emitting diode 611 is turned off, and the timer 10 is stopped (step S3).

[0040] Then, it is determined whether any of the MODE button 65 _{1-65 7} is depressed (step S
4) If pressed, the mode number corresponding to the pressed MODE button is written to the MODE register (step S5), and a display screen corresponding to the mode number written to this MODE register is displayed on the display 66. The display is switched so as to be performed (step S6).

Next, it is determined whether or not the LR trigger flag is ON (step S7). If it is ON, the hand has crossed from left to right. In this case, the maximum value Amax (Amax of the Amax register) With reference to the peak value, an operation instruction of “L → R” corresponding to the mode and control target information corresponding to the maximum value Amax are sent to a target device (for example, a sequencer, a sound source, an effector, etc.) (step S8). Thereafter, the LR trigger flag is turned off, and the Amax register and the Bmax register are cleared to "0" (step S9). If the LR trigger flag is OFF, it is determined whether or not the RL trigger flag is ON (step S10). If it is ON, the hand has crossed from right to left, and in that case, Bmax
By referring to the maximum value Bmax of the register, an operation instruction and control target information corresponding to the mode are sent to a target device (for example, a sequencer, a sound source, an effector, etc.) (step S1).
1), the RL trigger flag is turned off, and the Amax register and the Bmax register are cleared to "0" (step S1).
2). Next, other necessary processing is performed (step S
13), the above processing is looped and repeated (S2 to S1)
3).

The “other necessary processing” is “VERTICAL” before the trigger processing is performed in response to the ON of the RL trigger flag or the LR trigger flag.
The item to be controlled displayed below the item is displayed by changing the display form of the item to be controlled of the operation instruction performed by the trigger processing to another (for example, brightly illuminating or inverting the background black and white). May be performed. That is, the larger of the values of the Amax register and the Bmax register is "VALUE".
Is determined, and based on that, "VE
The display form of the items arranged under "RTICAL" is changed and displayed. By doing so, the operator can know in advance what the control target that is to be instructed to be operated before executing the operation instruction (before being triggered at the left / right intermediate position). The wrong process is not executed during the process.

Hereinafter, detailed examples of the modes 1 to 7 will be described. [Mode 1] FIG. 13 shows a display screen of mode 1. This mode 1 is a mode for giving an operation instruction for controlling the sequencer. When the object is moved from right to left above the beam controller, a phrase corresponding to the maximum value Bmax (peak value) at that time is triggered (start of performance) when the object passes through the right and left intermediate points. On the other hand, when the object is moved from the left to the right above the beam, the maximum value Ama at that time is obtained when the object passes through the left and right intermediate point.

When a stop instruction is issued by the movement of, the reproduction stop instruction of the corresponding phrase is sent to the sequencer with reference to the peak value of the Amax register.

[Mode 2] FIG. 14 shows a display screen of mode 2. This mode 2 is also a mode for giving an operation instruction for controlling the sequencer. Moving the object from right to left above the beam controller triggers a one-shot trigger to play the phrase corresponding to the peak value of the Bmax register only once when the object passes through the middle point between left and right. On the other hand, when the object is moved from the left to the right above the beam controller, when the object passes through the middle point between the left and right, a loop trigger is performed so as to repeatedly play the phrase corresponding to the peak value of the Amax register. Further, if the object is moved from left to right again after triggering the phrase in a loop, the loop reproduction of the phrase corresponding to the peak value of the Amax register is stopped when the object passes through the middle point between left and right.

I have. At this time, if the corresponding phrase has already been loop-played (repeatedly played), an instruction to stop loop playback is sent to the sequencer.

[Mode 3] FIG. 15 shows a display screen of mode 3. This mode 3 is a mode for giving operation instructions for controlling the sequencer and the effector. When the object is moved from right to left above the beam controller, the phrase corresponding to the peak value of the Bmax register is applied to the effect “O
N "to start playback. When the object is moved from left to right above the beam controller, a phrase corresponding to the peak value of the Amax register is triggered by the effect “OFF” when the object passes through the middle point between left and right. At this time, the effect switch 9 is instructed to switch the effect “ON / OFF” in accordance with the type of the effect stored in the phrase data.

VE / EQ ”.

When the CPU 3 is triggered from right to left, the CPU 3 refers to the peak value of the Bmax register and sends an instruction to reproduce the phrase corresponding to the trigger to the sequencer 7, and the type of the effect corresponding to the phrase. Is sent to the effector 9. When the trigger is triggered from left to right, an instruction to reproduce the corresponding phrase with reference to the peak value of the Amax register is sent to the sequencer 7. At this time, no effect is applied to the phrase.

[Mode 4] FIG. 16 shows a display screen of mode 4. This mode 4 is a mode for giving an operation instruction for controlling the sequencer 7. When the object is moved from right to left above the beam controller, when the object passes through the left and right intermediate point, the PHRAS of the RAM 5
Trigger the phrases registered in E1 to PHRASE3 in order. That is, for example, if this operation is performed after the reproduction of PHRASE1, PHRASE2 is reproduced. In short, it is "play next phrase". At this time, the volume of the reproduced phrase is reproduced in a volume corresponding to the peak value of the Bmax register. When the object is moved from left to right above the beam controller, the phrases registered in the RAM 5 are triggered in reverse order when the object passes through the left and right intermediate points. For example, PHRASE
If this operation is performed after playback of 3
To play. In short, it is "playback of previous phrase". At this time, the volume of the phrase to be reproduced is reproduced at a volume corresponding to the peak value of the Amax register.

When the CPU 3 is firstly triggered by a right-to-left operation, the sequencer issues an instruction to reproduce the first phrase stored in the RAM 5 in the corresponding volume by referring to the peak value of the Bmax register. Send to 7. At this time, the pointer is set to the reproduced phrase, and when the trigger is again triggered from the right again, the pointer is moved to the next phrase, and the next phrase is referred to by the corresponding volume by referring to the peak value of the Bmax register. An instruction to reproduce is sent to the sequencer 7.

When the CPU 3 is triggered by a left-to-right operation, the CPU 3 refers to the peak value of the Amax register, moves the corresponding pointer to the previous phrase, and replaces the previously triggered phrase with the previous phrase. By referring to the Amax register, an instruction to reproduce in the corresponding volume is sent to the sequencer 7. In this mode 4, the volume is controlled in accordance with the height in the vertical direction. However, the present invention is not limited to this, and an instruction such as a panpot or tempo is sent to the sequencer 7 in accordance with the height in the vertical direction. Is also good.

[Mode 5] FIG. 17 shows a display screen of mode 5. This mode 5 is a mode for giving an operation instruction for controlling the sequencer 7. Moving the object from right to left above the beam controller triggers a phrase corresponding to the peak value of the Bmax embodiment when the object passes through the left and right midpoint. At this time, whether or not another sequence or music data is being reproduced by the sequencer 7, the phrase is triggered and reproduction is started. On the other hand, when the object is moved from left to right above the beam controller, when the object passes through the left and right intermediate point, A
Trigger the phrase corresponding to the peak value in the max register. At this time, if the music data is being reproduced by the sequencer 7, the performance of the music by the sequencer 7 is muted to trigger a phrase. At this time, if the performance of the music on the sequencer 7 has already been muted, the muting is released.

On the display screen, the operation instruction content “MUTE ON ON” when the operation is performed from left to right is displayed below “L → R”.

3 ".

When the CPU 3 is triggered by an operation from right to left, the CPU 3 refers to the peak value of the Bmax register and sends a reproduction start instruction of the corresponding phrase to the sequencer 7, and is triggered by an operation from left to right. In this case, an instruction to start reproduction of the corresponding phrase is sent to the sequencer 7 with reference to the peak value of the Amax register, and an instruction to mute the music data played by the sequencer 7 is sent to the sequencer 7. Has become. At this time, if the music data of the sequencer 7 has already been muted, an instruction to cancel muting is sent to the sequencer 7. Therefore, when the music data is not reproduced by the sequencer 7, the phrase is triggered in the same manner from both the left and right sides.

[Mode 6] FIG. 18 shows a display screen of mode 6. This mode 6 is a mode for giving an operation instruction for controlling only the sound source 8. It is assumed that the tone colors that can be generated by the sound source 8 are set for each group as follows. Group number Group name Tone number Tone name: 1 Piano 1 Piano 1 1 Piano 2 Piano 2 1 Piano 3 Honky Tonk 2 Bass 1 Pick Bass 2 Bass 2 Wood Bass 2 Bass 3 Fretless Bass 3 Guitar 1 Clean Guitar 3 Guitar 2 Nylon Guitar 3 Guitar 3 distortion guitar...,...,...,.

When the object is moved from right to left above the beam controller, when the object passes through the left and right intermediate point,
The peak value = 0 to 5 according to the peak value of the Bmax register.
When the value is 0, the tone color group number is incremented. When the peak value is 51 to 99, the tone color number is incremented. When the object is moved from the left to the right above the beam controller, the tone color group number or the tone color number is decremented according to the peak value of the Amax register when the object passes through the middle point between the right and left.

On the display screen, the operation instruction content “decrement” when the operation is performed from left to right is displayed below “L → R”, and the operation is performed from right to left below “L ← R”. "Increment" is displayed when the operation instruction is issued.
In the "VERTICAL" column, it is possible to select whether a timbre group number or a timbre number is transmitted to the sound source 8 according to the vertical height of the object. The range of peak values to select them is "VAL
"UE" is displayed as "0 to 50".

When the CPU 3 is triggered by an operation from right to left, the CPU 3 sends an instruction to increment the timbre group number or timbre number to the sound source 8 with reference to the peak value of the Bmax register, and performs an operation from left to right. , The tone generator 8 sends a tone color group number or an instruction to decrement the tone color number to the sound source 8 with reference to the peak value of the Amax register.

In this mode 6, the timbre of the sound source 8 is switched by the operation of moving the object. However, the present invention is not limited to this, and can be applied to all parameters relating to the sound source 8. Further, for example, the control of the sequencer 7 may be performed instead of the control of the sound source 8 so that a phrase stored in the sequencer ROM 71 can be selected by incrementing / decrementing the phrase number. That is, the 100 phrases stored in the sequencer ROM 71 are divided into categories, and category numbers are assigned to the respective categories. Further, phrase numbers are assigned to the phrases included in each category number, and the tone group of mode 6 described above is assigned to the phrase. The category number and the tone number are used as the phrase numbers, and the category number or the phrase number is incremented or decremented in accordance with the right-to-left operation or the left-to-right operation of the object.

[Mode 7] FIG. 19 shows a display screen of mode 7. This mode 7 is a mode for giving an operation instruction for controlling only the effector 9. The effector 9 includes a plurality of effect patches composed of a combination of three types of effectors. The effect patches to be added can be selected by the other operators 64 in FIG.

The information is stored in a register (not shown) in the RAM 5.

When triggered by an operation from right to left, the CPU 3 sends an instruction to turn on the corresponding effect to the effector 9 with reference to the peak value of the Bmax register, and executes the operation from left to right. Amax if triggered
Refer to the peak value of the register and select the corresponding effect.
An instruction to set to FF is sent to the effector 9.

In the mode 7, the type of the effect is switched by moving the object. However, the present invention is not limited to this, and all parameters relating to the effector can be controlled by the same method.

As specific examples of the modes in the apparatus of this embodiment, in addition to those described above, various modes such as mode 8 to mode 10 described below are possible. These will be described below, but illustration is omitted.

[Mode 8: Sequencer control + sound source control]
This mode 8 is a mode in which a control operation instruction is given to the sequencer 7 and the sound source 8. Moving an object from right to left above the beam controller triggers the phrase corresponding to the peak value of the Bmax register when the object passes through the middle point between left and right. Modulation and pitch bend are applied with magnitudes corresponding to the detection value RA and the detection value RB (= current values A, B) of No. 2. This control is released when the value of the detection value RA or the detection value RB becomes 100 or more. Also, moving an object from left to right above the beam controller will simply trigger the phrase corresponding to the peak value of the Amax register when the object passes through the middle point between left and right. In this case, the modulation or pitch bend Is not controlled by moving the object.

On the display screen, below “L → R”, the operation instruction content “TRIGER + C” when the operation is performed from left to right
ONTROL ON ”is displayed, and below“ L ← R ”, the operation instruction content“ TRIGER ”when operated from right to left is displayed.
+ CONTROL OFF "is displayed. "VER
The number of the phrase triggered according to the height in the vertical direction is displayed in the column of “TICAL”, and the range of the peak value for selecting them is set to “0 to 33” in the column of “VALUE”.
It is displayed as follows. In this mode 8, after triggering the phrase, a parameter name for controlling the phrase selected in "VERTICAL" is displayed at the bottom of the screen, for example, "CONTROL = MODULATION".
And so on.

[Mode 9: Sound Source Control] This mode 9
This is a mode in which a control operation instruction for the sound source 8 is issued. The sound source 8 is a sound source including a filter. When the object is moved from right to left above the beam controller, after the object passes through the right and left intermediate points, the infrared sensor 2 responds to the current detection value RA (after passing the left and right intermediate points) and the detected value RB. The value allows the resonance of the filter to be variably controlled. When the object is moved from the left to the right above the beam controller, the cutoff of the filter is performed by a value corresponding to the detection value RA and the detection value RB of the infrared sensor 2 after the object passes through the left and right intermediate point. Can be variably controlled. Note that if the value of the detection value RA or the detection value RB is 1
When it becomes 00 or more, the control of these filters is released.

On the display screen, a parameter name “resonance” controlled when operated from left to right is displayed below “L → R”, and a right to left parameter is displayed below “L ← R”. Is displayed, the parameter name "cut-off" controlled when the operation is performed. The column of “VERTICAL” indicates that the parameter is continuously variably controlled by moving in the vertical direction after the object passes through the middle point between the left and right sides.
"ENCIAL CONTROL" is displayed. The sound source parameters such as “cut-off” set under “L → R” and “L ← R” may be selectable and set with other operators 64 on the panel.

[Mode 10: Sound Source Control] This mode 10
Is a mode in which a control operation instruction for the sound source 8 is issued. The sound source 8 includes an LFO (low frequency oscillator). When the object is moved from the right to the left above the beam controller, after the object passes through the left and right intermediate points, L is a value corresponding to the current detection values RA and RB of the infrared sensor 2 and L
The LFO depth (amplitude) of the FO can be variably controlled. When the object is moved from left to right above the beam controller, the LFO rate (period) is determined by a value corresponding to the detection value RA and the detection value RB of the infrared sensor after the object passes through the left and right intermediate points. Can be variably controlled. The value of the detection value RA or the detection value RB is 100
At this point, the above control is released.

On the display screen, under “L → R”, the parameter name “LFO” controlled when the operation is performed from left to right.
Depth "is displayed, and the parameter name" LFO rate "controlled when operated from right to left is displayed under" L ← R "
Is displayed. The column of “VERTICAL” indicates that the parameter can be continuously variably controlled by moving up and down after the object passes through the middle point between the left and right.
"EQUENCIALCONTROL" is displayed.

In the embodiment described above, a predetermined operation instruction is issued when the detection value RA and the detection value RB of the infrared sensor 2 become the same value.
The operation instruction may be issued when the difference between A and the detection value RB falls within a predetermined range, or when the ratio between the detection value RA and the detection value RB becomes a predetermined ratio. May be performed.

In the above embodiment, the position of the object in the up-down direction and the position of the object from which the two infrared rays LE
A variety of controls are performed by detecting whether the vehicle has reached the intermediate point of D, but a control according to the moving speed may be added by detecting the speed at which the object moves. . The detection of the speed can be realized by monitoring the Amax register and the Bmax register and detecting the time from the peak value of one of the registers to the intermediate point of the object.

As an application in this case, for example, the type of code is specified according to the height of the object. Also, the sound order of the constituent sounds of the chord is designated by the upstroke order in accordance with the operation from right to left, and the downstroke order in accordance with the operation from left to right. Furthermore, the timing and velocity at which the constituent sound is generated are specified according to the speed of the object. With this timing and velocity specification, if the speed is high, the sound of the remaining constituent sounds is sounded at a high timing after the sound of the first constituent sound, and at a large volume. If the speed is low, the remaining constituent sounds are generated at a later timing after the first constituent sound is generated, and at a lower volume. The display screen in this case is displayed as shown in FIG.

According to this method, if the trigger is caused by moving the object quickly from right to left, the sounding timing of the constituent sound is advanced, and the downstroke is sounded at a large volume. On the other hand, if the trigger is performed by slowly moving the object from left to right, the sounding of the constituent sound is delayed, and the upstroke is sounded at a low volume. This is exactly what makes simulation of guitar playing techniques possible.

In implementing the present invention, various modifications other than those described above are possible. For example, in the above embodiment, two infrared light emitting diodes 1A, 1B and 1
The movement of the object to the left and right is detected using the two infrared sensors 2 and the content of the operation instruction is changed depending on whether the movement is from right to left or from left to right. If the different processing is performed only according to the peak value (that is, the height) generated by the movement, the above-described embodiment can be simplified and the control can be performed with only one infrared light emitting diode and one infrared sensor. It is possible.

That is, the beam irradiation direction of the infrared light emitting diode 1A in the apparatus of the above-described embodiment is set to be perpendicular to the panel surface, and the light receiving surface of the infrared sensor 2 is also arranged upward in the same direction, and the infrared light emitting diode 1B is removed. In this case, the light emitting diode 1A is turned on continuously instead of in a time-division manner. Detecting the detection value RA every predetermined time,
If the detected value RA is increasing, the detected value RA is stored as the maximum value in the Amax register, and when the detected value RA starts to decrease, the value of the Amax register is set as a peak value, and the value is set according to the magnitude of the peak value. That is, predetermined processing is executed. Note that such a peak value indicates that the object is moving horizontally from the left or right direction and the infrared sensor 2
When you pass just above or when you return in the opposite direction,
Or, it occurs when the object is moved from top to bottom and returned upward in the middle.

In this case, the following registers and flags are set in the RAM 5. A register: present detection value R from light emitting diode 1A
A is stored as the current value A. Amax register: stores the maximum value Amax of the current value A up to the present. Trigger flag: When ON, instructs execution of processing. Maximum value writing permission flag: When ON, writing of the maximum value is permitted. Once execution of processing is instructed, the detection value RA
The maximum value write flag is "OFF" until the value becomes "0"
Therefore, the next processing is not performed.

In this embodiment, the following four modes 11 to 14 can be set by the MODE button. [Mode 11: Sequencer Control] When the detected value RA is no longer the maximum value (that is, when the value of the Amax register has reached the peak value), an instruction to reproduce the phrase corresponding to the maximum value Amax is sent to the sequencer 7. [Mode 12: Sequencer Control] When the detected value RA is no longer the maximum value (that is, when the value of the Amax register has reached the peak value), the sequencer issues a reproduction / stop instruction of the music data corresponding to the maximum value Amax. Instruct 7. [Mode 13: Sound Source Control] When the detected value RA is no longer the maximum value (that is, when the value of the Amax register has reached the peak value), the sound source is instructed to switch to the tone corresponding to the maximum value Amax. [Mode 14: Effect control] When the detected value RA is no longer the maximum value (that is, when the value of the Amax register has reached the peak value), the effector 9 is instructed to switch to the effect type corresponding to the maximum value Amax. To instruct.

The operation of this embodiment will be described below with reference to the flowcharts of FIGS. FIG. 21 is a flowchart of the main routine. FIG.
Is a timer interrupt routine.
Executed every 3ms interrupt to 3 First, the timer interrupt processing routine shown in FIG. 22 will be described. This timer interrupt routine is based on the light emitting diode 1A.
Are sequentially detected, and based on these detected values, update processing of the maximum value Amax of the detected values, on / off processing of the trigger flag, on / off processing of the maximum value write permission flag, and the like are performed. Is what you do.

When the timer interrupt processing routine is started, first, processing relating to the light emitting diode 1A is performed (step S61). This processing is to store the current detection value RA detected by the infrared sensor 2 as the current value A in the A register. When the current value A is obtained, it is next determined whether the maximum value write permission flag is ON or OFF (step S62). If ON, it means that the maximum value Amax can be updated. Therefore, it is determined whether the current value A is equal to or greater than the maximum value Amax (step S63). Amax is updated by replacing the current value A with the current value A (step S66).
If it is smaller than x, it is determined that the maximum value Amax has reached the peak value, and the trigger flag is set to "ON" (step S64). After the trigger flag is set to "ON", the maximum value write permission flag is turned off so that the maximum value Amax detected as the peak value does not fluctuate (step S65), so that the maximum value Amax is not rewritten. . The reason why the maximum value write permission flag is turned off is the same as in the above-described embodiment.

If it is determined in step S62 that the maximum value write permission flag is OFF, it is determined whether or not the current value A = 0 (step S67). It is determined whether or not the current operation instruction by hand from the inside to the outside has ended. When the current operation instruction is completed, the OFF maximum value write permission flag is set ON again in preparation for the next operation instruction (step S68), and the timer interrupt routine is ended.

Next, the main routine shown in FIG. 21 will be described.
