Description

  The present invention relates to an electronic music apparatus capable of performing various types of music control according to the movement mode by moving a hand or the like in a space. The electronic music apparatus according to the present invention can be used for performing music control in an electronic musical instrument, for example. 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, a keyboard, a drum machine, an effect processor, an effect pedal, a sequencer, and a tone generator module. Is included.

  2. Description of the Related Art Conventionally, there is known a non-contact type electronic music apparatus that optically detects a movement of a hand or the like in a predetermined space and gives an operation instruction. This device has one light source (infrared light emitting diode, etc.) 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. When the reflected light from the hand is received by the light receiver, when the amount of received light exceeds a certain threshold value, the predetermined operation instruction is turned on and the threshold value is not exceeded. In this case, switch-like control is performed to turn it off.

  In the conventional non-contact type electronic music apparatus described above, the intensity distribution of the irradiation light beam from the light source is as shown in FIG. In this case, the amount of light received by the light receiver is different between the case where the hand is placed directly above the light source and the case where the hand is placed on the side, even at the same height. Therefore, if an on / off operation instruction is to be made depending on whether or not the amount of received light exceeds a predetermined threshold, if the operation instruction is simply made using only the height of the hand as a guide, a malfunction will occur. There is a high possibility of end. That is, the conventional electronic music apparatus of this type has a problem that it is difficult for an operator to recognize how much a hand is brought close to a sensor and whether the switch is turned on or off. There is a point. Further, as the contents of the operation instruction, only binary control of whether or not to perform certain music control, that is, ON or OFF for a predetermined one process can be performed.

  The present invention has been made in view of such problems, and enables desired music control to be reliably performed by moving an object in an operation space, and further various changes in the movement mode of the object. The purpose is to enable music control of various contents.

  In order to solve the above-described problems, an electronic music apparatus according to the present invention, as a first mode, outputs music and controls music according to the movement mode of an object that moves the music in a predetermined operation space. An electronic music device that directs light to the operation space, and one or more light sensors that receive light reflected by an object in the operation space from the light source. Optical means arranged so as to have at least two paths of light from the object to the optical sensor and outputting detection values corresponding to the amount of light received through the paths, and music Signal generating means for generating, and music control means for controlling 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 relationship. Is. In this electronic music apparatus, based on the detection value of reflected light from an object that has passed through at least two paths, the mutual relationship between the detection values of each path is a predetermined relationship, for example, when they become the same value. Since the music control instruction is performed, the position of the object where the music control instruction is generated in the operation space is relatively uniquely determined as compared with the case where there is one light source and one optical sensor each. The operator can accurately grasp the timing at which the music control instruction is generated in accordance with the movement operation of the object.

  For example, this optical means is composed of two light sources arranged on a straight line and one photosensor arranged at the center, and each light source generates light alternately in time, If the light from the light source is received in a time-sharing manner, two types of detection values are obtained, and the position where these detection values are the same is usually considered to be near the optical sensor. The person can accurately grasp the timing at which the music control instruction is issued as the object moves. The above-mentioned “predetermined relationship” is not limited to “when the detection value of each route becomes the same value” as described above. For example, “the difference between the detection values of each route is within a predetermined range. Or “when the ratio of the detection values of each path reaches a predetermined value”. The light from the light source described above may be not only normal visible light but also infrared light or ultraviolet light.

In addition, as the above-described music control instruction, when the electronic music apparatus according to the present invention is applied to, for example, an electronic musical instrument, the music control includes automatic performance apparatus control, sound source control, and effect applying apparatus (effector). ) Control including the control of). In this case, the following control is specifically targeted.
Automatic performance device: Performance information playback instruction, stop instruction, loop playback instruction, mute instruction, volume instruction, panpot instruction, performance information switching, etc. Sound source: tone group switching instruction, tone number switching instruction, sound source waveform switching instruction Filter cutoff and resonance instructions, LFO depth and rate instructions, envelope instructions, etc.
Effect applying device: Effect ON / OFF instruction, effect type switching instruction, and the like.

  An electronic music device according to the present invention is a second embodiment of an electronic music device that outputs music and controls the music according to a movement mode of an object that moves in a predetermined operation space. An optical means comprising: a light source that irradiates light to the operation space; and an optical sensor that receives light reflected by an object in the operation space, and outputs a detection value corresponding to the amount of light received by the optical sensor; Triggered by the peak value detecting means for detecting the peak value of the detected value appearing as the object moves, the signal generating means for generating music, and the peak value detecting means detecting the peak value Music control means for controlling music generated by the signal generation means. For example, if an object is approached from the upper side toward the optical sensor and is inverted at a desired height and this time the object is moved away, a clear peak value is generated in the detected value, and based on this peak value If the music control instruction is performed, the operator can accurately generate the peak value, and thus the music control instruction can be performed accurately. The determination that the peak value is detected may be a case where the current detection value is compared with the maximum value of the detection value, and the current detection value falls below the maximum value. It may be a case where a predetermined value is below the maximum value. The peak value detection means may detect a peak value of a detection value detected after the detection value detected by the optical means becomes smaller than a predetermined value.

  An electronic music apparatus according to the present invention is a electronic music apparatus that outputs music and controls the music in accordance with a movement mode of an object that moves in a predetermined operation space, as a third mode. One or more light sources that irradiate light to the operation space and one or more optical sensors that receive light reflected by an object in the operation space, and light from the light source through the object to the optical sensor. Optical means arranged to have at least two paths, and output detection values corresponding to the amount of light received through each path, and the detection values of the detection values for each of the paths. Depending on the mutual relationship between the maximum value detection means for detecting the maximum value up to the present, the signal generation means for generating music, and the maximum value of the detection value of each path, a predetermined type of the signal generation means One of different music control modes It is obtained and selecting means for selecting a music control mode. With this configuration, the maximum value of the detected value of each path with respect to the movement of the object takes various patterns according to the movement mode of the object, so that the contents of the operation instruction can be changed according to the movement mode. Therefore, it is possible to enrich the contents of operation instructions. For example, the optical means is composed of two light sources arranged on the left and right straight lines and one photosensor arranged at the center position, and each light source generates light alternately in time, and each light source has a light source. If the light from the light is received in a time-sharing manner, two types of detection values can be obtained. In this configuration, the object moves from the right to the left and moves above the photosensor, and moves from the left to the right. Since the maximum value of the detected value of each route differs when the light sensor is over, the music control instruction having different contents can be selected according to each moving mode. In this case, for example, when the detection value of each route becomes the same, by looking at the magnitude relationship of the maximum value of the detection value of each route that has been stored and updated, it is possible to determine from which direction the object is moved. Detect and perform different control depending on the operation direction (right to left or left to right). The maximum value detection 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.

  According to a fourth aspect of the present invention, there is provided an electronic music device that outputs music and controls the music according to a movement mode of an object that moves in a predetermined operation space. An optical means comprising: a light source that irradiates light to the operation space; and an optical sensor that receives light reflected by an object in the operation space, and outputs a detection value corresponding to the amount of light received by the optical sensor; The peak value detecting means for detecting the peak value of the detected value that appears as the object moves, the signal generating means for generating music, and the range that the peak value can be obtained in advance are divided into two or more ranges. Different types of music control modes of the signal generation means are assigned to each range, and the music control mode corresponding to the range to which the peak value belongs is selected according to the peak value detected by the peak value detection means With a selection means to Those were example. For example, if an object is approached from the upper side toward the optical sensor and is inverted at a desired height and this time the object is moved away, a clear peak value is generated in the detected value, and based on this peak value If the contents of the music control instruction are changed, the contents of the music control instruction can be variously set according to the height position where the object is reversed from the approaching state to the distant state. Therefore, if the contents of the music control instruction are changed according to the range of the peak value (that is, according to the height of the movement of the object), the contents of the music control instruction performed according to the movement mode of the object can be further enriched. it can. Also, in this device, the operator recognizes at which height position the reversal is to be performed, so that a peak value corresponding to each position can be accurately generated. Can be selected accurately. As described above, the determination that the peak value is detected may be a case where the current detection value is compared with the maximum value of the detection value, and the current detection value falls below the maximum value, It may be a case where the detection of is lower than the maximum value by a predetermined value. The peak value detection means may detect a peak value of a detection value detected after the detection value detected by the optical means becomes smaller than a predetermined value.

  Moreover, the electronic music apparatus which concerns on this invention is a maximum value detection means which detects the maximum value to the present of the said detected value about each of the detected value of each said path | route in the above-mentioned 1st form as a 5th form. And a selection means for selecting one of the plurality of different music control modes of the predetermined type of the signal generation means in accordance with the correlation between the maximum values of the detected values of the respective paths. And the music control means performs music control in the music control mode selected by the selection means when the mutual relationship between the current values of the detected values of the respective paths has become a predetermined relation. Is.

  According to a sixth aspect of the present invention, there is provided an electronic music apparatus according to a sixth aspect of the music control mode selected by the selection unit when the peak value detection unit detects a peak value in the fourth mode. The music control means for performing the music control is provided.

  Moreover, the electronic music apparatus according to the present invention can also be configured in a form in which the first, third, and fourth forms are combined. That is, this electronic music apparatus is an electronic music apparatus that outputs music and controls the music according to the movement mode of an object that moves in a predetermined operation space, and irradiates the operation space with light 1 The above light source and one or more optical sensors that receive light reflected by the object in the operation space have at least two light paths from the light source to the optical sensor through the object. Optical means arranged to output a detection value corresponding to the amount of light received through each path, and a maximum for detecting the maximum value of the detection value to date for each of the detection values of each path A maximum value selecting means for selecting one of the maximum values according to the mutual relationship between the maximum value of the detected values of the respective paths, a signal generating means for generating music, Divide the range into two or more ranges. A selection means for selecting a music control mode corresponding to a range to which the maximum value selected by the maximum value selection unit belongs, It is assumed that music control means for controlling the control mode of the music selected by the selection means is provided when the mutual relationship between the current values of the detected values of the respective paths becomes a predetermined relation.

  Each of the electronic music devices described above includes speed calculation means for determining the moving speed of the object based on the detected value, and ranges of values that the moving speed can take, divided into two or more ranges, for each range. And a fourth selection unit that assigns the content of the operation instruction and selects an operation instruction having a content corresponding to the range to which the moving speed belongs according to the value of the moving speed obtained by the speed calculating unit. . According to this configuration, the contents of the operation instruction can be changed depending on the obtained difference in the moving speed of the object, so that the contents of the operation instruction to be performed according to the movement mode of the object can be further enriched.

  In each of the electronic music apparatuses described above, the optical means is composed of two light sources arranged apart from each other and one optical sensor arranged therebetween, and each light source generates light alternately in time. The optical sensor can be configured such that light from each light source is received in a time division manner. For example, by tilting the optical axes of two light sources outward, it is possible to irradiate light so that the operation space has at least a part of the irradiation area that does not overlap, and the object movement detection mechanism is compact. Can be configured.

  Each of the electronic music devices described above can employ a tone generation means for generating a tone as the signal generation means. At this time, each music control unit described above can instruct the tone generation unit to control the characteristics of the generated tone. The control of the characteristics of the musical tone includes, for example, control of whether or not an effect is applied to the musical tone, selection of the tone color of the musical tone to be generated, and the like. Similarly, the selection means described above can instruct the musical sound generation means to select the control mode of the characteristics of the generated musical sound. The selection of the control mode of the characteristics of the musical sound includes, for example, selection of whether or not to add an effect to the musical sound, selection of the tone color of the musical sound to be generated, selection of the type of effect applied to the musical sound, and the like. In addition, as the above-described musical sound generating means, a musical sound can be generated by reading data representing a phrase stored in advance. At this time, each of the music control devices described above can instruct the music sound generation means to perform control related to reading of data expressing the phrase. The control related to reading is, for example, start or stop of reading of data representing a phrase, or selection of a phrase to be read. Similarly, the selection means described above can instruct the musical sound generation means to select a mode relating to reading of data expressing the phrase. The selection of the aspect related to reading is, for example, starting or stopping reading of data expressing a phrase, or selecting a phrase to be read.

  As described above, according to the present invention, desired music control can be reliably performed by moving an object in the operation space. In addition, music control of various contents can be performed by changing the movement mode of the object.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a hardware configuration diagram when an electronic music apparatus according to an embodiment of the present invention is applied to an electronic musical instrument, and two infrared light emitting diodes and one infrared sensor are provided in an optical sensor portion for detecting hand movement. Used. In FIG. 1, 1A and 1B are infrared light emitting diodes (hereinafter simply referred to as light emitting diodes), and 2 is an infrared sensor for detecting infrared rays. 3 is a CPU (central processing unit) that performs overall control of the apparatus, 4 is a main body ROM that stores a control program and various tables, 5 is a working RAM that stores various registers and flags to be described later, Reference numeral 6 denotes various operators and indicators arranged on the panel, 7 is a sequencer, 8 is a sound source, 9 is an effector, and 10 is a timer, which are connected to each other via a bus 11.

  The sequencer 7 can perform up to eight phrases simultaneously, and the performance data of 100 phrases is stored in a ROM (sequencer ROM 71) inside the sequencer. In addition to these phrases, the sequencer 7 can reproduce one piece of music data, and 10 pieces of music data are stored in the sequencer ROM 71. The sound source 8 has a multi-timbral configuration with a simultaneous sound number of “128”, and the sequencer 7, the sound source 8, the effector 9, and the bus 11 are connected as shown in the figure. The timer 10 is started when a beam controller button shown in FIG. 2 described later is pressed and turned ON, interrupts the CPU 3 every 5 ms, and executes a timer interrupt routine described later.

  FIG. 2 shows an external view of the panel of the apparatus of this embodiment. A beam controller comprising two light emitting diodes 1A and 1B and an infrared sensor 2 is disposed on the panel. The light emitting diodes 1A and 1B are arranged in a horizontal row as viewed from the front side of the panel of the electronic musical instrument, and the infrared sensor 2 is arranged in the middle. The space above the beam controller on the panel becomes an operation space for performing an operation instruction by moving an object (specifically, usually a hand). The beam controller is turned ON / OFF by a toggle operation of a beam controller button 61 provided in the vicinity thereof.

  The light emitting diodes 1A and 1B are controlled to be turned on in a time-sharing manner so that the light emission timings are staggered, and therefore, the infrared light beam is not simultaneously irradiated into the operation space. The light emitting diodes 1A and 1B are provided such that the beam irradiation direction is inclined outward from the vertical direction of the panel. FIG. 5 shows an isolevel curve of the infrared beam irradiated from the light emitting diodes 1A and 1B. FIG. 5 is an equilevel curve when the electronic musical instrument of the embodiment is viewed from the front side in the horizontal direction on the panel surface, and the infrared beams of the light-emitting diodes 1A and 1B are inclined toward each other. I understand. In this way, the inclination is provided on the outer side by shifting the irradiation space of the infrared beam irradiated by the respective light emitting diodes 1A and 1B in the left-right direction as viewed from the front, thereby moving the object in the operation space in the left-right direction. This is to make it possible to reliably detect the moving operation of. In addition, such an arrangement has an advantage that the apparatus can be made compact.

  The infrared sensor 2 is an element that receives an infrared beam irradiated from the light emitting diodes 1A and 1B and reflected by an object in the operation space and outputs an electric quantity corresponding to the received light level. Since the light-emitting diodes 1A and 1B are controlled to be turned on in a time-sharing manner, the infrared sensor 2 receives the infrared rays (reflected light) of the light-emitting diodes 1A and 1B at alternating timings. In this embodiment, the level of infrared rays irradiated from the light emitting diode 1A and reflected from the object is “detection value RA”, and the level of infrared rays irradiated from the light emitting diode 1B and reflected from the object is “detection value RB”. .

  The other operation element 64 is an operation element used for selecting a phrase registered in the PHASE 1 register to the PHASE 3 register provided in the RAM 5 and an operation element for selecting music data to be reproduced by the sequencer. Since a general one is adopted, a detailed explanation is omitted. MODE buttons 651 to 657 are operators for selecting a mode to be described later, and any one of modes 1 to 7 can be selected. The PLAY button 62 is a button for reproducing the selected music data, and the STOP button 63 is a button for stopping reproduction.

  The phrase performance data stored in the ROM 71 in the sequencer 7 has a data structure as shown in FIG. That is, in addition to the performance data of a phrase, the type of effect that is preferable to be used in the phrase (for example, chorus, reverb, etc., used in a specific example of mode 3 to be described later) is stored.

FIG. 4 shows the configuration of data stored in the RAM, and includes the following registers and flags.
MODE register: Indicates the number of the current mode (initialized to MODE = 1 when the power is turned on).
A register: indicates the current detection value RA as the current value A (initialized to 0 when the power is turned on).
B register: indicates the current detection value RB as the current value B (initialized to 0 when the power is turned on).
Amax register: indicates the maximum value Amax of the detected value RA to date (initialized to 0 when the power is turned on).
Bmax register: indicates the maximum value Bmax of the detected value RB up to the present (initialized to 0 when the power is turned on).
Maximum value write enable flag: A flag indicating whether or not writing to registers Amax and Bmax is permitted (initialized to ON when the power is turned on). ON indicates write permission, OFF indicates write prohibition.
LR trigger flag: A flag indicating that the object has moved from the left to the right above the beam controller as viewed from the front of the panel and has passed through the left and right intermediate points (near the infrared sensor 2) (initialized to OFF when the power is turned on) )
RL trigger flag: A flag indicating that the object has moved from right to left and passed through the left and right intermediate points (initialized to OFF when the power is turned on).
PHASE 1 register: indicates the number of a phrase registered as the first phrase.
PHASE2 register: indicates the number of the phrase registered as the second phrase.
PHASE 3 register: indicates the number of the phrase registered as the third phrase.

  The operation of this embodiment apparatus will be described below. In this embodiment apparatus, various operation instructions can be given by moving an object up and down, left and right in an operation space above the beam controller provided on the panel. This operation instruction is whether the object is moved from the right to the left when viewed from the front of the panel, or from the left to the right, how much is the height of the object viewed from the panel surface at that time, The contents of the operation instructions can be changed according to the situation.

  Since the light emitting diodes 1A and 1B of the beam controller are provided so that the beam irradiation direction is inclined outward, for example, an object (for example, a hand) is placed in the direction of the arrow (the direction from left to right) in FIG. As it moves, the detected values RA and RB of the light emitting diodes 1A and 1B exhibit characteristics as shown in FIG. In FIG. 6, the horizontal axis indicates the position of the object in the horizontal direction as viewed from the front surface of the beam controller (panel front surface), and the vertical axis indicates the detection values RA and RB. First, the characteristics of 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 (vertex 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 mountain shape with a peak value of RBpeak, except that the position where the detection value RB reaches the peak value is in the vicinity of 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 of FIG. 6, the position where the two detection values RA and RB are the same at the same time is near the position directly above the infrared sensor 2, and the object is moved at what height on the panel at that time. The magnitudes (absolute values) of the detection values RA and RB vary depending on whether they are set. Further, it can be determined whether the object is moved from the right to the left or the left to the right depending on which side of the detection values RA and RB has the peak value first. In the apparatus of this embodiment, the contents of the operation instructions are switched according to the movement mode of these objects, and the contents of the operation instructions are also switched for each mode.

  This mode is selected by pressing one of the MODE buttons 651 to 657. 13 to 19 show specific display screens corresponding to the modes 1 to 7, respectively. This display screen is displayed on the display 66 on the panel. The contents of detailed operation instructions 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 detailed contents of modes 1 to 7 shown in FIGS. 13 to 19 will be described later. In FIG. 13, the display screen displays the detection values RA and RB corresponding to the light emitting diodes 1A and 1B in the form of “L: OO” and “R: XX”, respectively, and the current mode number is “MODE = It is shown in the form of “△”. Also, under “L → R”, the contents of operation instructions to be given to a predetermined target device (for example, a sequencer, a sound source, an effector, etc.) corresponding to the movement of the object from left to right are shown. , “L ← R” shows the contents of the operation instruction to be performed in response to the movement from right to left. The contents of this operation instruction include, for example, a performance stop instruction to the sequencer by “L → R”, a phrase reproduction start instruction by “L ← R”, and the like. In the “VERTICAL” column, control targets (phrase numbers in the example of FIG. 13) selected according to the height range of the hand in the vertical direction are displayed, and the detection value corresponding to each height range is displayed. The range is displayed in the “VALUE” column. As the detected value is closer to “99”, the height is lower as viewed from the panel surface, and as the detected value is closer to “0”, the height is higher.

  The operation of this embodiment apparatus will be described below with reference to the flowcharts of FIGS. 8 and 9 are flowcharts of the main routine. FIGS. 10 and 11 are timer interrupt routines, which are executed for every interrupt of 5 ms from the timer 10 to the CPU 3. FIG. 12 is a flowchart of processing relating to a light emitting diode.

  First, the timer interrupt processing routine shown in FIGS. 10 and 11 will be described. This timer interrupt routine sequentially detects the detection values RA and RB corresponding to the light emitting diodes 1A and 1B, and based on these detection values, updates the maximum values Amax and Bmax of the detection values, the LR trigger flag and the RL An on / off process of a trigger flag, an on / off process of a maximum value write permission flag, and the like are performed.

  When the timer interrupt processing routine is started, first, processing related to the light emitting diode 1A is performed (step S21). FIG. 12 shows a flowchart of this process. The light emitting diode 1A is caused to emit light (step S41), and the current detection value RA detected by the infrared sensor 2 (that is, the detection value corresponding to the reflected light from the object with respect to the light emitting diode 1A) is stored as the current value A in the A register. (Step S42), the light emitting diode 1A is turned off (Step S43). When the process related to the light emitting diode 1A is completed, the same process related to the light emitting diode 1B is performed (step S22). As a result, the light emitting diodes 1A and 1B emit light alternately, and the detection values RA and RB from the light emitting diodes 1A and 1B can be obtained in a time division manner.

  If 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 it is ON, it means that the maximum values Amax and Bmax can be updated. Therefore, it is first determined whether or not the current value A is equal to or greater than the maximum value Amax (step S24), and the current value A is equal to or greater than the maximum value Amax. If the current value A is smaller than the maximum value Amax, the maximum value Amax is updated as if it has already reached the peak value. Do not do. Next, it is determined whether or not the current value B is greater than or equal to the maximum value Bmax (step S26), and if it is greater than or equal to the maximum value Bmax, the maximum value Bmax is updated by replacing it with the current value B (step S27). If the current value B is smaller than the maximum value Bmax, 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). If the two current values A and B are equal, it means that the hand is in the left and right intermediate position (near the infrared sensor 2), as can be seen from the characteristic diagram of FIG. In this case, the magnitude relationship between the maximum values Amax and Bmax is determined (step S29). If Amax ≧ Bmax, the object moves from left to right and reaches the intermediate position (when Amax> Bmax). Alternatively, it can be estimated that the object is swung up and down near the intermediate position (when Amax = Bmax), and if Amax <Bmax, it can be estimated that the object has moved from right to left. If Amax ≧ Bmax, it is determined whether or not the current value A is smaller than the maximum value Amax (step S30). This determination is made to see whether the current value A is still increasing or has entered a decreasing state, so that the current maximum value Amax is the peak value of the characteristic related to the current value A (the peak of the mountain). Can be determined. If the current maximum value Amax is the peak value, it can be determined that the object has moved from the left to the right and has reached the intermediate position between the left and right, and therefore the LR 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 once ended so that the maximum value Amax can be further updated after the next time.

  If it is determined in step S29 that Amax <Bmax, a similar comparison process is performed for the detected value B and the maximum value Bmax (step S32). If the maximum value Bmax is a peak value, the object has moved from right to left. It is determined that the left / right intermediate position has been reached, 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 values Amax and Bmax are set. Is not rewritten. As will be described later, when the LR trigger flag or the RL trigger flag is turned ON, a phrase performance start instruction or the like is triggered, but the current values A and B are increased by changing the hand movement immediately after the trigger. In some cases, 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 given, “VALUE” corresponds to a small phrase (corresponding to the first phrase). ) May be selected as a control target and triggering may not be possible. Therefore, after triggering, the maximum value write permission flag is turned OFF and the current value A or B once falls below a predetermined value (0). Otherwise, the maximum value is not updated.

  Therefore, when it is determined in step S23 that the maximum value write permission flag is OFF, it can be considered that the hand held over the beam controller has passed the left and right intermediate positions (that is, triggered). In this case, when the current value A or B becomes “0” (steps S35 and S36), it is determined that the hand has once left the operation space and the current operation instruction by the hand has ended. In this case, in preparation for the next operation instruction, the OFF maximum value write permission flag is set to ON again (step S37), and the timer interrupt routine is terminated.

  As described above, in this timer interrupt routine, the maximum values (peaks) of the current values A and B (= detected value RA and detected value RB) are stored in the Amax register and the Bmax register in the RAM 5, respectively. Therefore, in the Amax register and the Bmax register, as shown in FIG. 7, for example, when the object is moved from left to right, the value of the Amax register does not change from the position (a) in the figure. 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 (position (A) in the figure), the size of the Amax register and the Bmax register are compared. Then, 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 (in the case of mode = 1 described later, the process of “stopping phrase 2”) ). When execution of processing is instructed, the Amax register and Bmax register are cleared to “0”, but writing to the Amax register and Bmax register is prohibited until the current value A and current value B become “0”. It is like that.

  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 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), and if it has been operated, a toggle operation is performed by that operation, so that what has been turned off so far is switched on. For example, the light emitting diode 611 for display is turned on, and the timer 10 for starting a timer interrupt is started. On the other hand, if what has been turned on by the operation has been switched to OFF, the display light emitting diode 611 is turned off and the timer 10 is stopped (step S3).

  Next, it is determined whether any of the MODE buttons 651 to 657 has been pressed (step S4). If pressed, the mode number corresponding to the pressed MODE button is written to the MODE register (step S5). The display is switched so that a display screen corresponding to the mode number written in the MODE register is displayed on the display 66 (step S6).

  Next, it is determined whether or not the LR trigger flag is ON (step S7). If the flag is ON, the hand has crossed from left to right. In this case, the maximum value Amax (peak value) of the Amax register is determined. , The control target information corresponding to the operation value “L → R” corresponding to the mode and the maximum value Amax is sent to the target device (eg, sequencer, sound source, 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 the LR trigger flag is ON, the hand has crossed from right to left. By referring to the maximum value Bmax, an operation instruction and control target information corresponding to the mode are sent to the target device (eg, sequencer, sound source, effector, etc.) (step S11), the RL trigger flag is turned OFF, and the Amax register and Bmax register are set. It is cleared to “0” (step S12). Next, other necessary processing is performed (step S13), and the above processing is looped and repeated (S2 to S13).

  In addition, as the “other necessary processing”, before the trigger processing is performed in response to the ON of the RL trigger flag or the LR trigger flag, the trigger for the item to be controlled displayed under “VERTICAL” is displayed. A process may be performed in which the display mode of the item to be controlled by the operation instruction performed by the process is changed from that of another item (for example, brightly lit or the background is reversed in black and white). That is, it is determined which range of “VALUE” the larger of the values of the Amax register and the Bmax register falls, and based on this, the display form of the items arranged under “VERTICAL” is changed and displayed. It has become. By doing so, the operator can know in advance what the control target is to be instructed before executing the operation instruction (before triggering at the middle position between the left and right). The wrong process is not executed in the middle.

Hereinafter, detailed specific examples of 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 left and right intermediate points. On the other hand, when the object is moved from left to right above the beam, the performance of the phrase corresponding to the maximum value Amax (peak value) at that time is stopped when the object passes through the left and right intermediate points.

  On the display screen, “STOP” is displayed when “L → R” is operated from left to right, and when “L ← R” is operated from right to left The operation instruction content “TRIGER” is displayed. In the “VERTICAL” column, the number of the phrase to be triggered / stopped according to the height in the vertical direction of the object is displayed, and the setting of the peak value range for controlling them is displayed in the “VALUE” column. 0-33 ".

  When the trigger is instructed by the movement of the object 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, and the object moves from left to right. When a stop instruction is given, a peak stop value of the Amax register is referred to and a corresponding phrase playback stop instruction is sent to the sequencer.

  [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. When the object is moved from right to left above the beam controller, a one-shot trigger is performed so that the phrase corresponding to the peak value of the Bmax register is played only once when the object passes through the left and right intermediate points. 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 left and right intermediate points, a loop trigger is performed so that the phrase corresponding to the peak value of the Amax register is repeatedly played. Furthermore, when the phrase is triggered by a loop and then the object is moved again from the left to the right, the loop playback of the phrase corresponding to the peak value of the Amax register is stopped when the object passes through the left and right intermediate points.

  On the display screen, the operation instruction content “LOOP TRIGER / LOOP STOP” when operated from left to right is displayed under “L → R”, and from right to left under “L ← R”. The operation instruction content “ONE SHOT TRIGER” when operated is displayed. In the “VERTICAL” column, the number of the phrase that is triggered according to the height in the vertical direction is displayed, and in the “VALUE” column, the range of peak values corresponding to the height of each phrase is, for example, “0 to 33”. "Is displayed.

  When the CPU 3 is instructed to trigger the movement from right to left, it refers to the peak value of the Bmax register and sends an instruction to start playback of the corresponding phrase in one shot (one-time playback). When triggered by a movement from left to right, an instruction to loop-play the corresponding phrase is sent to the sequencer with reference to the peak value of the Amax register. At this time, if the corresponding phrase has already been played back in a loop (repeated playback), an instruction to stop the loop playback is sent to the sequencer.

  [Mode 3] FIG. 15 shows a display screen of mode 3. 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 triggered by the effect “ON” to start reproduction when the object passes through the left and right intermediate points. When the object is moved from left to right above the beam controller, the phrase corresponding to the peak value of the Amax register is triggered with the effect “OFF” when the object passes through the left and right intermediate points. At this time, an effect switching “ON / OFF” instruction is given to the effector 9 in accordance with the type of effect stored in the phrase data.

  On the display screen, the operation instruction content “EFFECT ON + TRIGER” when operated from left to right is displayed under “L → R”, and operated from right to left under “L ← R”. The operation instruction content “EFFECT OFF + TRIGER” is displayed. In the “VERTICAL” column, the number of the phrase that is triggered according to the height in the vertical direction is displayed, and in the “VALUE” column, the range of peak values corresponding to the height of each phrase is, for example, “0 to 33”. "Is displayed. In mode 3, the effect type corresponding to the three phrases registered in the PHASE of the RAM is displayed as “CHORUS / REVERVE / EQ” in the “EFFECT TYPE” column at the bottom of the screen. It is like that.

  When the CPU 3 is triggered from the right to the left, the CPU 3 refers to the peak value of the Bmax register, sends an instruction to reproduce the phrase corresponding to the peak value to the sequencer 7, and gives the type of effect corresponding to the phrase. An instruction is sent to the effector 9. When triggered from left to right, the sequencer 7 is instructed to reproduce the phrase corresponding to the peak value of the Amax register. 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, the phrases registered in PHRASE 1 to PHRASE 3 of the RAM 5 are triggered in order when the object passes through the left and right intermediate points. That is, for example, when this operation is performed after reproducing PHASE1, PHASE2 is reproduced. In short, it becomes “next phrase playback”. At this time, the volume of the phrase to be reproduced is reproduced with 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, when this operation is performed after the PHASE3 is reproduced, the PHASE2 is reproduced. In short, it becomes “Previous phrase playback”. At this time, the volume of the phrase to be reproduced is reproduced with a volume corresponding to the peak value of the Amax register.

  On the display screen, the operation instruction content “PRIVIE PHRASE TRIGER” when operated from left to right is displayed under “L → R”, and operated from right to left under “L ← R”. The operation instruction content “NEXT PHRASE TRIGER” is displayed. In the “VERTICAL” column, “VOLUME CONTROL” is displayed, indicating that the phrase is triggered at a volume corresponding to the height in the vertical direction.

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

  When the CPU 3 is triggered by a left-to-right operation, the corresponding pointer is moved to the previous phrase by referring to the peak value of the Amax register, and the previously triggered phrase is changed to the Amax register. An instruction to reproduce with the corresponding volume is sent to the sequencer 7 by referring to it. In this mode 4, the volume is controlled according to the height in the vertical direction. However, the present invention is not limited to this, and a panpot or tempo instruction is sent to the sequencer 7 according to the height in the vertical direction. 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. When the object is moved from right to left above the beam controller, the phrase corresponding to the peak value of the Bmax embodiment is triggered when the object passes through the left and right intermediate points. At this time, whether or not another phrase or song data is being reproduced by the sequencer 7, the phrase is triggered to start reproduction. On the other hand, when the object is moved from left to right above the beam controller, the phrase corresponding to the peak value of the Amax register is triggered when the object passes through the left and right intermediate points. 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 and the phrase is triggered. At this time, if the musical performance of the sequencer 7 has already been muted, the muting is canceled.

  On the display screen, “MUTEON TRIGER / MUTE OFF” is displayed when “L → R” is operated from left to right, and “L ← R” is displayed from right to left. The operation instruction content “TRIGER” when operated is displayed. The “VERTICAL” column displays the number of the phrase that is triggered according to the height in the vertical direction, and the peak value range for selecting those phrase numbers is “0 to 33” in the “VALUE” column. Is displayed.

  When the CPU 3 is triggered by a right-to-left operation, the CPU 3 sends a corresponding phrase playback start instruction to the sequencer 7 with reference to the peak value of the Bmax register, and when triggered by a left-to-right operation. Sends the instruction to start playback of the corresponding phrase to the sequencer 7 with reference to the peak value of the Amax register, and sends to the sequencer 7 an instruction to mute the performance of the song data being played by the sequencer 7. . At this time, if the music data of the sequencer 7 has already been muted, an instruction to cancel the mute 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 way from both the left and right.

[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 timbres 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 11 Piano 2 Piano 21 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 ............ The sound source 8 generates timbres according to these tone group numbers and tone numbers sent from the CPU 3.

  When the object is moved from right to left over the beam controller, the timbre group number is incremented when the peak value = 0 to 50 according to the peak value of the Bmax register when the object passes through the left and right intermediate points. When the peak value = 51 to 99, the timbre number is incremented. When the object is moved from left to right above the beam controller, the timbre group number or timbre number is decremented according to the peak value of the Amax register when the object passes through the left and right intermediate points.

  On the display screen, the operation instruction content “decrement” when operated from left to right is displayed under “L → R”, and when operated from right to left under “L ← R” The operation instruction content “Increment” is displayed. In the “VERTICAL” column, it is possible to select whether a timbre group number or a timbre number is sent to the sound source 8 in accordance with the vertical height of the object. The range of peak values for selecting them is displayed as “0-50” in the “VALUE” column.

  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 the timbre number with reference to the peak value of the Bmax register, and is triggered by an operation from left to right. If it is, the tone value group number or an instruction to decrement the tone color number is sent 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 an object moving operation. However, the present invention is not limited to this, and can be applied to all parameters related to the sound source 8. Further, for example, the sequencer 7 may be controlled instead of the control of the sound source 8, and the phrase stored in the sequencer ROM 71 may be selected by incrementing / decrementing the phrase number. That is, the 100 phrases stored in the sequencer ROM 71 are divided into categories and assigned category numbers, and the phrase numbers are assigned to the phrases included in each category number. The category number or tone number is used as a phrase number, and the category number or phrase number is incremented or decremented according to the operation from right to left of the object or from left to right.

  [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 made up of combinations of three types of effectors. An effect patch to be added can be selected by the other operation element 64 shown in FIG.

  When the object is moved from right to left above the beam controller, the effect corresponding to the peak value of the Bmax register is turned on when the object passes through the left and right intermediate points. When the object is moved from left to right above the beam controller, the effect corresponding to the peak value of the Bmax register is turned off when the object passes through the left and right intermediate points.

  On the display screen, the effect “ON” that is the operation instruction content when operated from left to right is displayed under “L → R”, and the operation is performed from right to left under “L ← R”. The effect “OFF” which is the content of the operation instruction in the case of being performed is displayed. In the “VERTICAL” column, three types of effects in the effect patch (in this example, wah, distortion, reverb) are displayed above and below to select the type of effect to be controlled ON / OFF. The range of the peak value is displayed as “0 to 33” in the “VALUE” column. The three types of effects under the column “VERTICAL” are set by the other operation elements 64, and are stored in a register in the RAM 5 (not shown).

  When the CPU 3 is triggered by a right-to-left operation, the CPU 3 sends an instruction to turn on the corresponding effect with reference to the peak value of the Bmax register to the effector 9 and is triggered by the left-to-right operation. In this case, an instruction to turn off the corresponding effect with reference to the peak value of the Amax register is sent to the effector 9.

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

  In addition to what has been described above, various modes such as mode 8 to mode 10 shown below are possible as specific examples of modes in this embodiment apparatus. These will be described below, but illustration is omitted.

  [Mode 8: Sequencer Control + Sound Source Control] This mode 8 is a mode for instructing control operations to the sequencer 7 and the sound source 8. 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 triggered when the object passes through the left and right intermediate points. Modulation and pitch bend are applied with a magnitude corresponding to the detection value RA of 2 and the detection value RB (= current values A and B). Note that this control is canceled when the detection value RA or the detection value RB reaches 100 or more. Also, if the object is moved from left to right above the beam controller, the phrase corresponding to the peak value of the Amax register is simply triggered when the object passes through the left and right intermediate points. In this case, modulation or pitch bend is performed. Is not controlled by moving the object.

  The display screen displays “TRIGER + CONTROL ON” when “L → R” is operated from left to right, and “L ← R” is operated from right to left. The operation instruction content “TRIGER + CONTROL OFF” is displayed. In the “VERTICAL” column, the number of the phrase that is triggered according to the height in the vertical direction is displayed, and the peak value range for selecting them is displayed in the “VALUE” column such as “0 to 33”. Is displayed. In this mode 8, after triggering the phrase, the parameter name that controls the phrase selected by “VERTICAL” is displayed at the bottom of the screen, for example, “CONTROL = MODULATION”. It has become.

  [Mode 9: Sound source control] This mode 9 is a mode for instructing the sound source 8 to perform control operations. The sound source 8 is a sound source provided with a filter. When the object is moved from right to left above the beam controller, the object passes through the left and right intermediate points, and then corresponds to the current detection value RA and detection value RB of the infrared sensor 2 (after passing the left and right intermediate points). The value allows the filter resonance to be variably controlled. When the object is moved from the left to the right above the beam controller, the filter is cut off with 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 points. Can be controlled variably. When the detection value RA or the detection value RB reaches 100 or more, the control of these filters is cancelled.

  On the display screen, the parameter name “Resonance” controlled when operated from left to right is displayed under “L → R”, and operated from right to left under “L ← R”. The parameter name “Cut off” is displayed. The column “VERTICAL” displays “SEQUENCE CONTROL” indicating that the parameter is continuously variably controlled by moving in the vertical direction after the object passes through the left and right intermediate points. Sound source parameters such as “cut-off” set under “L → R” or “L ← R” may be selected and set by the other operation elements 64 of the panel.

  [Mode 10: Sound Source Control] This mode 10 is a mode for instructing the sound source 8 to perform control operations. The sound source 8 includes an LFO (low frequency oscillator). When the object is moved from right to left above the beam controller, the LFO LFO depth is set to a value corresponding to the current detection value RA and detection value RB of the infrared sensor 2 after the object passes through the left and right intermediate points. (Amplitude) can be variably controlled. When the object is moved from the left to the right above the beam controller, the LFO rate (cycle) is set to a value corresponding to the detection value RA and detection value RB of the infrared sensor after the object passes through the left and right intermediate points. Can be controlled variably. When the detection value RA or the detection value RB reaches 100 or more, the above control is released.

  The display screen displays the parameter name “LFO Depth” that is controlled when operated from left to right under “L → R”, and operates from right to left under “L ← R”. The parameter name “LFO rate” to be controlled in the case of being set is displayed. The column “VERTICAL” displays “SEQUENCE CONTROL” indicating that the parameter is continuously variably controlled by moving in the vertical direction after the object passes through the left and right intermediate points.

  In the above-described embodiment apparatus, a predetermined operation instruction is performed when the detection value RA and the detection value RB of the infrared sensor 2 become the same value, but the detection value RA and the detection value RB An operation instruction may be issued when the difference falls within a predetermined range, or an operation instruction may be issued when the ratio of the detected value RA and the detected value RB reaches a predetermined ratio. .

  In the above-described embodiment, the position of the object in the vertical direction and the position from which the object is moved to the middle point between the two infrared LEDs are detected, and various controls are performed. The speed at which the object moves may be detected, and control according to the moving speed may be added. This speed detection can be realized by monitoring the Amax register and the Bmax register and detecting the time from when one of them reaches the peak value until the object reaches the intermediate point.

  As an application in this case, for example, the type of code is designated according to the height of the object. In addition, the order of sound generation of the chords is designated in accordance with the right-to-left operation, and the order of sounding in the up-stroke according to the operation from left to right. Furthermore, the timing and velocity at which the constituent sounds are generated are designated according to the speed of the object. In this timing and velocity designation, if the speed is fast, the remaining constituent sounds after the first constituent sound are pronounced at a fast timing and at a high volume. On the other hand, if the speed is slow, the remaining constituent sounds after the first constituent sound are generated at a slow timing and with a small volume. Further, the display screen in this case is displayed as shown in FIG.

  According to this method, if the object is moved quickly from right to left and triggered, the sounding timing of the constituent sounds is accelerated and the downstroke is sounded with a large volume. On the other hand, if the object is moved slowly from left to right and triggered, the sounding of the constituent sounds is delayed and the upstroke is pronounced at a low volume. It is possible to simulate a guitar cutting technique.

  In the practice of the present invention, various modifications other than those described above are possible. For example, in the above-described embodiment, the left and right movements of the object are detected by using the two infrared light emitting diodes 1A and 1B and one infrared sensor 2, and the movement from right to left or left to right is detected. The contents of the operation instructions are changed accordingly, but if the different processing is merely performed according to the peak value (ie, height) created by the movement of the object in the space, the above-described embodiment is simplified. Control can be performed with only one infrared light emitting diode and one infrared sensor.

  That is, the beam irradiation direction of the infrared light emitting diode 1A in the above-described embodiment apparatus is set perpendicular to the panel surface, and the light receiving surface of the infrared sensor 2 is also arranged in the same direction upward, and the infrared light emitting diode 1B is removed. In this case, the light-emitting diode 1A is lit continuously rather than time-divisionally. The detected value RA is detected every predetermined time. If the detected value RA increases, the detected value RA is stored in the Amax register as the maximum value. When the detected value RA starts to decrease, the value of the Amax register is peaked. As a value, a predetermined process corresponding to the magnitude of the peak value is executed. Such a peak value is obtained when the object moves horizontally from the left or right direction and passes right above the infrared sensor 2 or returns to the opposite direction in the middle, or the object moves from top to bottom. Occurs when moving up and returning from the middle.

In this case, the following registers and flags are set in the RAM 5.
A register: Stores the current detection value RA from the light emitting diode 1A as the current value A.
Amax register: Stores the maximum value Amax of the current value A up to the present time.
Trigger flag: Instructs execution of processing when ON.
Maximum value write permission flag: When ON, writing of the maximum value is permitted. Once the execution of the process is instructed, the maximum value write flag is set to “OFF” until the detection value RA becomes “0”, so the next process is not performed.

In the apparatus of 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 becomes the peak value), a playback instruction for the phrase corresponding to the maximum value Amax is sent to the sequencer 7.
[Mode 12: Sequencer control] When the detected value RA is not the maximum value (that is, when the value of the Amax register reaches the peak value), the sequencer issues a song data playback / stop instruction corresponding to the maximum value Amax. 7 is instructed.
[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 becomes the peak value), the sound source is instructed to switch to the timbre 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 reaches the peak value), the effector 9 is instructed to switch to the effect type corresponding to the maximum value Amax. Instruct.

  The operation of the apparatus of this embodiment will be described below with reference to the flowcharts of FIGS. Here, FIG. 21 is a flowchart of the main routine. FIG. 22 shows a timer interrupt routine which is executed for every interrupt of 5 ms from the timer 10 to the CPU 3. First, the timer interrupt processing routine shown in FIG. 22 will be described. This timer interruption routine sequentially detects the detection value RA corresponding to the light emitting diode 1A, and based on these detection values, the update processing of the maximum value Amax of the detection value, the on / off processing of the trigger flag, the maximum value writing The permission flag is turned on / off.

  When the timer interrupt processing routine is started, first, processing related to the light emitting diode 1A is performed (step S61). This process is a process of storing the current detection value RA detected by the infrared sensor 2 in the A register as the current value A. If the current value A is obtained, it is next determined whether the maximum value write permission flag is ON or OFF (step S62). If it is ON, it means that the maximum value Amax can be updated. Therefore, it is determined whether or not the current value A is equal to or greater than the maximum value Amax (step S63). Amax is updated by replacing it with the current value A (step S66). If the current value A is smaller than the maximum value Amax, 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), and the maximum value Amax is not rewritten. . The reason for turning off the maximum value write permission flag 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), so that the hand held over the beam controller is removed from the operation space. It is determined whether or not the current operation instruction by hand has ended. When the current operation instruction is completed, in preparation for the next operation instruction, the turned off maximum value write permission flag is set to ON again (step S68), and the timer interrupt routine is terminated.

  Next, the main routine shown in FIG. 21 will be described. When the power of the embodiment apparatus is turned on, first, the various registers and flags provided in the RAM 5 are initialized (step S51). Next, panel processing corresponding to steps S2 to S6 of the above-described embodiment is performed (step S52). Next, it is determined whether or not the trigger flag is ON (step S53). If the trigger flag is ON, the maximum value Amax (peak value) of the Amax register is referred to and the target device (eg, sequencer, sound source, effector, etc.) is in the mode. An operation instruction corresponding to is sent (step S8). Thereafter, the trigger flag is turned OFF, and the Amax register is cleared to “0” (step S55). Next, other necessary processing is performed (step S13), and the above processing is looped and repeated (S2 to S13).

  In this embodiment apparatus, the current value A is compared with the maximum value Amax, and the music control is started when the current value A falls below the maximum value Amax. However, the present invention is not limited to this. For example, the music control may be started when the current value A falls below a maximum value Amax by a predetermined value. For example, assuming that the predetermined value is 5 and the current maximum value Amax is 50, the process is not executed while the current value A is decreasing from 50 to 45, and the process is not performed until 44 or less. To execute. By doing so, it is possible to prevent the processing from being performed unintentionally due to subtle movements of the object or noise from the outside world.

  Further, in the implementation of the present invention, the following modifications are possible in addition to those described above.
