  However, in the above-described conventional performance device, sound generation data is set in advance for each designated point, and music is formed by repeatedly producing sound at each designated point based on this setting. For this reason, since the same music is repeated at a predetermined interval, the degree of freedom of composition is limited. Similarly, in the case of the light emission pattern, since the same light emission pattern is repeated at a predetermined interval, the degree of freedom of the light emission pattern is limited, and the user may get bored.

  For this reason, an object of the present invention is to provide a performance device capable of forming a musical piece and a light emission pattern with a higher degree of freedom with different sound generation intervals and light emission states for each designated point.

The performance device according to the present invention includes a plurality of key switches in which the X and Y coordinates are two-dimensionally arranged in the range of (1, 1) to (m, n), and each has a light emitting element therein. depending on a sound and a light emitting playing device, a counting means for counting a storage means for storing a light emission pattern, a pressing down time of detecting the selection of the selected key switch of the light emitting elements of said plurality of key switches, wherein When the pressing time measured by the time measuring means reaches a predetermined time or more , the light emission pattern is read out, and based on the light emission pattern, the light emitting elements of the key switches around the selected key switch as the pressing time elapses the emit light, and control means to shift to a push mode in which the by going emission control allowed to emit light around the key switch of the key switch light is emitted sequentially, the It is characterized in that was example.

  In this configuration, when a key switch is selected, a musical tone is produced with the sound quality, tone length and pitch assigned to the key switch. At the same time, the light emitting element provided in the key switch emits light with a preset light emission pattern. Accordingly, various light emission patterns can be obtained depending on the selection time of the key switch.

Further , the light emission pattern of the light emitting elements in a predetermined region including the light emitting elements provided in the key switch is changed.

Further, in the performance device of the present invention, the storage means stores sounding data corresponding to each of the plurality of key switches and effect information of the sounding data, and the control means shifts to the push mode , The effect information is read out, and the sounding data assigned to the selected key switch is effected in time series and output as the pressing time elapses .

In this configuration, when the selection time of the key switch is equal to or longer than a predetermined time length, a musical tone is generated with the sound quality, tone length, and pitch assigned to the selected key switch being effected.
The performance device according to the present invention is characterized in that when the selection of the selected key switch is released by the control means, the push mode is released.

According to the present invention, it is possible to realize a light emission pattern and a sound generation pattern that do not generate a repetitive pattern with a relatively short period. At this time, the user need only perform the operation of selecting the key switch, and thereby, it is possible to easily play a musical composition and a light emission pattern with a higher degree of freedom and a higher degree of freedom.

  A performance device according to a first embodiment of the present invention will be described with reference to the drawings. This performance device is provided with a plurality of key switches arranged in a matrix on a substantially rectangular parallelepiped plate-shaped casing, and plays a musical piece by selecting a desired number of key switches. In addition, this musical performance device can obtain sound generation data and light emission patterns of different sound generation patterns according to the distance between the selected key switch group and the predetermined end of the matrix display area. As a result, the performance device of the present embodiment can easily perform a musical composition with a higher degree of freedom and a higher degree of freedom than a conventional performance device, and can easily realize a complicated light emission pattern.

FIG. 1 is a front view of the performance device 1 of the present embodiment.
FIG. 2 is a diagram showing the configuration of the switch group 10 and the light-emitting display unit 110 when the performance device 1 of FIG. 1 is viewed from the front side (user side).

  The performance device 1 has a substantially rectangular parallelepiped flat plate-shaped casing 500 and is supported by a stand 400. The casing 500 includes a key switch group 10 including key switches 100 arranged on a top surface thereof in a two-dimensional matrix. In the key switch group 10, 16 key switches 100 are arranged in the vertical direction and the horizontal direction, respectively, and a total of 256 key switches 100 are two-dimensionally arranged as a whole.

  The key switch 100 is, for example, a push-type switch, and a light emitting display unit 110 including an LED or the like is disposed therein. All of the light emitting display portions 110 constitute a light emitting display portion group 11. The light emitting display unit 110 emits light when the key switch 100 is pressed by the user. The light emitting display unit group 11 emits light in a predetermined pattern according to a combination of pressing a control switch 22 and a key switch 100 described later.

  The positions of the key switches 100 of the key switch group 10 and the light emitting display portions 110 of the light emitting display portion group 11 are shown in a two-dimensional coordinate system in which the vertical direction is the Y coordinate and the horizontal direction is the X coordinate. Here, in the following description, the coordinates of the key switch 100 at the left end and the lower end in FIG. 2 are mtSW (1, 1), and the coordinates of the key switch 100 at the right end and the upper end are mtSW (16, 16). ). Further, according to this arrangement, the coordinates of the left and lower light emitting display units 110 in FIG. 2 are mtLED (1, 1), and the coordinates of the right and upper light emitting display units 110 are mtLED (16). 16).

  Control buttons 22A to 22D are arranged on the left frame portion from the user side of the key switch group 10 and the light emitting display unit group 11 in the casing 500, and control buttons 22E to 22H are arranged on the right frame portion. Further, the control button 22I and the stereo speaker 80 are disposed on the upper frame portion of the casing 500, and the control buttons 22J and 22K and the liquid crystal display unit 21 are disposed on the lower frame portion. In addition, an input terminal 23 to which one end of the connection cable 300 is connected is disposed on the side surface of the housing 500 on the upper frame side. The other end of the connection cable 300 is connected to another performance device that is a communication partner, and the performance device 1 communicates with another performance device via the connection cable 300.

  FIG. 3 is a block diagram showing an electrical configuration of the performance device 1 shown in FIG.

  The performance device 1 includes a main CPU 2, a ROM 3, a storage unit 4, a RAM 5, a sound source 6, a matrix display input unit 9, a display unit 21, a control switch 22, a timer 13, an input / output unit 14, an other unit communication I / F 24, and a communication A structure in which the I / F 25 is connected via the bus line 15 is provided.

  The ROM 3 stores a start program for starting the performance device 1. The storage unit 4 is, for example, a rewritable storage unit that can store data, such as a flash memory or a hard disk. The storage unit 4 stores a predetermined program such as a performance processing program for causing the performance apparatus 1 to perform a performance, and stores predetermined data necessary for executing the program. The predetermined data includes, for example, sound generation setting data. The sound generation setting data includes a correspondence relationship between each key switch 100 and a pitch assigned to each key switch 100 and a reference tone color set by default for the sound source 6. It is the data shown. The sound generation setting data is set based on, for example, the MIDI standard.

  The RAM 5 functions as a work area for the main CPU 2 and temporarily stores programs and data read from the storage unit 4. The RAM 5 includes a coordinate storage unit 51 and a correspondence storage unit 52 that indicate the coordinates of the key switch group 10 illustrated in FIG. 1.

  The coordinate storage unit 51 is a storage unit that stores the ON state of each key switch 100. The coordinate storage unit 51 is configured by a 16 × 16 table having the same shape as the arrangement of the key switch group 10 illustrated in FIG. 2, and the area corresponding to each key switch 100 is configured by a 1-bit flag. When the key switch 100 is continuously pressed for a predetermined time length, the area corresponding to the pressed key switch 100 is set to “1”. The state set to “1” is the ON state, and the state where the area corresponding to the key switch 100 is set to the reset “0” is the OFF state.

  In addition, the correspondence storage unit 52 stores a note number table T in which a list of note numbers to be assigned to each switch 100 is registered. In this embodiment, in the note number table T, 16 note numbers are assigned to Y coordinates = 1 to 16 in the initial setting, and set to have the same pitch for X coordinates = 1 to 16. Is done. Here, the note number is a numerical value for instructing the pitch etc. to the sound source 6 from the performance processing unit 201, which will be described later, and “60” is the central “scale (C4)”. In this embodiment, note numbers “60” to “75” are assigned to the Y coordinate, and the default settings at the time of activation are “60” for Y coordinate = 1 and “61” for Y coordinate = 2. ”And Y coordinates are assigned in order, and up to“ 75 ”is assigned to Y coordinates = 16. Note that note numbers may be independently assigned to all the switches 100 of 16 × 16 = 256. Further, the range of the assigned note numbers is not limited to “60” to “75”.

  The sound source 6 is, for example, a MIDI sound source, which generates a digital audio signal with a predetermined tone color and outputs it to the D / A converter 7. Here, the sound source 6 can generate a digital audio signal with external tone colors input from the outside along with a plurality of types of built-in tone colors (piano, guitar, etc.). The note number is associated with each switch 100 by the above-described note number table T. Therefore, a plurality of types of musical tone data are associated with each switch 100 by being assigned a note number. The sound source 6 receives a tone color designation (tone color designation) from the main CPU 2 and also receives a note number notification, whereby a digital audio signal based on the note number notified with the designated tone color is transmitted to a predetermined tone length (for example, (200 msec).

  The D / A converter 7 converts the digital audio signal input from the sound source 6 into an analog audio signal and outputs the analog audio signal to the sound system 8. The sound system 8 converts the input audio signal into sound and emits the sound from the speaker 80.

  The matrix display input unit 9 includes the key switch group 10, the light emitting display unit group 11, and the sub CPU 12 described above with reference to FIG.

  The sub CPU 12 detects the coordinates of the pressed key switch 100 (FIG. 2) and outputs it to the main CPU 2 as pressed key switch position information.

  The timer 13 measures time and notifies the main CPU 2. The input / output unit 14 is an interface circuit for inputting / outputting data between the various storage media 400 and the performance device 1 (main CPU 2). The control switch 22 is a switch that accepts various control commands.

  The main CPU 2 controls the operation of each connected component. The main CPU 2 functions as a performance processing unit 201, a movement route calculation unit 202, and a display processing unit 203 by executing a performance program.

  The performance processing unit 201 uses the sound generation setting data stored in the storage unit 4 to control the generation of the sound signal of the sound source 6 so as to generate sound corresponding to the key switch 100 on which the user has performed a performance operation. Specifically, the performance processing unit 201 performs tone specification on the sound source 6 with a predetermined initial tone color as initialization processing, and the note number corresponding to the Y coordinate of each switch in the note number table T with the above-described initial setting. Register.

  The performance processing unit 201 acquires the pressed key switch position information from the sub CPU 12 to detect the coordinates of the key switch 100 pressed by the user.

  The performance processing unit 201 refers to the note number table T to execute a sound generation process for specifying the note number corresponding to the notified coordinates and notifying the sound source 6. As a result, the sound source 6 generates a sound signal corresponding to the key switch 100 pressed by the user and having a set tone color.

  The movement route calculation unit 202 calculates a movement route mt having coordinates perpendicular to one side of the matrix display input unit 9 set in advance from the acquired coordinates of the key switch 100.

  FIG. 4 is a diagram showing the relationship between the obtained coordinates of the key switch 100 and the movement route of the so-called “bounce mode” shown below.

  As shown in the example of FIG. 4, the movement route mt has coordinates at predetermined time intervals vertically downward (along the Y-axis direction) from the coordinates selected by the key switch 100 toward the lower end of the matrix display input unit 9. When it moves gradually and reaches the coordinates of the lower end, it is a so-called “bounce”, a route that moves vertically upward (along the Y-axis direction) to reach the selected coordinates of the key switch 100. Further, the moving route mt “bounces” again at the selected coordinates of the key switch 100 and moves vertically downward. In other words, the movement route mt is a coordinate movement track that reciprocates between the selected coordinate of the key switch 100 and the coordinate of the lower end of the matrix display input unit 9 having the same X-axis coordinate.

  The movement route calculation unit 202 uses the selection timing of the key switch 100 as the start timing from the calculated movement route mt and the movement speed of the preset coordinates, and the coordinates of the selection key switch 100 and the coordinates of the lower end of the matrix display input unit 9. The coordinates of each key switch 100 between are given to the display processing unit 203 in order. In addition, the movement route calculation unit 202 gives the performance processing unit 201 the timing when the coordinates according to the calculated movement route mt reach the coordinates of the lower end of the matrix display input unit 9 and the coordinates of the selected key switch 100. .

  The performance processing unit 201 refers to the note number table T, and executes sound generation processing for notifying the sound source 6 at the notified timing. As a result, the sound source 6 generates a sound signal corresponding to the key switch 100 pressed by the user and having a set tone color. That is, in this “bounce mode”, the sound generation process corresponding to the selection key switch 100 from the sound source 6 at the timing when the coordinates on the movement route mt coincide with the coordinates of the selection key switch 100 and the coordinates of the lower end of the matrix display input unit 9. Is executed.

  Such calculation processing and sound generation processing of the movement route mt are performed in parallel for each selected key switch 100. That is, the calculation of the movement route mt and the sound generation process at a predetermined timing are performed for each selection key switch 100 individually. At this time, the coordinate movement speed of each movement route may be set to be the same or different.

  For this reason, the musical sound output from the sound source 6 is a sound assigned to each selection key switch 100 that is sounded at a sound generation cycle according to the distance between the selection key switch 100 and the lower end of the matrix display input unit 9. Since they are superposed, they are formed by a combination of very random sounds with low correlation. As a result, the musical sound output from the sound source 6 is very interesting and highly flexible in accordance with the key switch input timing from the user.

  The display processing unit 203 executes processing (display processing) for controlling the light emission display of the light emitting display unit group 11.

  FIGS. 5A and 5B are conceptual diagrams showing the light emission state of the matrix display input unit 9 in the bounce mode. FIG. 5A shows a point in time when a predetermined key switch 100 is selected, and FIG. 5B shows the matrix display input unit 9 from the selection key switch 100. (C) is when the moving coordinates reach the lower end of the matrix display input unit 9, and (D) is from the lower end of the matrix display input unit 9 to the selection key switch 100. The point in time when the movement coordinates move on the movement route mt is shown.

  In this display processing, the display processing unit 203 causes the light emitting display units 110 corresponding to the key switches 100 on the moving route mt to emit strong light sequentially based on the timing and coordinates given from the moving route calculating unit 202. For example, in the example of FIG. 5, when the user selects the key switch 100 of mtSW (13, 8), the mtLED (13, 8) is made to emit strong light at the time of selection (FIG. 5A), and sequentially described above. At this timing, the mtLED (13, Y1) emits strong light while moving the movement coordinate on the movement route mt downward (FIG. 5B). When the movement coordinates reach the lower end of the matrix display input unit 9, the mtLED (13, 1) corresponding to the key switch 100 at this position is caused to emit strong light (FIG. 5C). Then, sequentially, the mtLED (13, Y2) is caused to emit strong light while moving the movement coordinate on the movement route mt upward at the aforementioned timing (FIG. 5D). Then, the display processing unit 203 sequentially causes the light emitting display unit 110 on the movement route mt to emit light while reciprocating the movement coordinates on the movement route mt. Thus, it seems to the user that the light continues to move while bouncing back and forth between the selection key switch 100 and the lower end of the matrix display input unit 9 in conjunction with the sound generation.

  Such display processing is also performed in parallel for each selected key switch, and the period of reciprocation depends on the distance between each key switch and the lower end, and as shown in FIG. It is possible to obtain a display in which a plurality of lights that do not have bounce. FIG. 6 is a diagram showing the matrix display input unit 9 in a state where a plurality of key switches are selected in the bounce mode.

  Next, the operation process of the performance device of this embodiment will be described.

  FIG. 7 is a flowchart of the bounce mode process of the performance device of this embodiment.

  When the user continues to press the predetermined key switch 100 as described above, the sub CPU 12 of the matrix display input unit 9 sets the corresponding key switch 100 to the selected state, and displays the coordinate information corresponding to the selected key switch 100. This is given to the main CPU 2 (S1).

  From the acquired coordinates, the main CPU 2 calculates the movement route mt by calculating the coordinates of the lower end of the matrix display input unit 9 whose X coordinate is the same as that of the corresponding key switch 100 by the movement route calculation unit 202 ( S2). Further, the performance processing unit 201 of the main CPU 2 gives sound generation data corresponding to the selection key switch 100 to the sound source 6 to execute predetermined sound generation (S3), and the display processing unit 203 emits light corresponding to the selection key switch 100. The light emission quenching process of the display unit 110 is executed (S4).

  The moving route calculation unit 202 of the main CPU 2 sequentially gives coordinates along the calculated moving route mt so as to go downward of the matrix display unit 9 (S5), and until the lower end coordinate is given, the display processing unit 203 performs the light emission quenching process of the light emission display unit 110 for each given movement coordinate (S6 → S4).

  When the coordinates of the lower end on the movement route mt are given, the performance processing unit 201 of the main CPU 2 gives the sound generation data corresponding to the selection key switch 100 to the sound source 6 to execute predetermined sound generation (S6 → S7) and display. The processing unit 203 executes light emission quenching processing of the light emitting display unit 110 at the lower end coordinates (S8).

  When the coordinates reach the lower end of the matrix display input unit 9, the movement route calculation unit 202 of the main CPU 2 sequentially gives the coordinates along the calculated movement route mt so as to be directed upward of the matrix display unit 9 (S9). Until the coordinates of the selection key switch 100 are given, the display processing unit 203 executes the light emission quenching process of the light emitting display unit 110 for each given movement coordinate (S10 → S8).

  This loop process is continuously executed until a stop input is made by the user. Here, as a stop input method, for example, a method of pressing the key switch 100 corresponding to the coordinates of the lower end may be used. And this stop process can be set for every selection key switch, and the user can change the combination of the selection key switch 100 easily, and can change a music easily.

  In the above description, a coordinate system is set in which the horizontal direction is the X-axis direction, the vertical direction is the Y-axis direction, the X coordinate increases from the left side to the right side, and the Y coordinate increases from the lower side to the upper side. However, the definitions of these directions and the like are arbitrary and may be set as appropriate. As a result, the lower end of the matrix display input unit 9 is not set as the rebound end as described above, but the right end, the left end, and further the upper end can be set as the rebound end.

Next, a performance device according to a second embodiment will be described with reference to the drawings.
This embodiment has the same mechanical and electrical configuration as the first embodiment, but differs in sound generation processing and light emission quenching processing. Therefore, description of the same parts as those in the first embodiment is omitted.

  In addition to the sound generation setting data for each key switch 100, the storage unit 4 stores effect information of sound generation data when the key switch 100 is kept pressed for a predetermined time or more in the “push mode” described in detail below. I remember it. Similarly, the storage unit 4 also stores a light emission pattern of the light emission display unit 110 when the key switch 100 is kept pressed for a predetermined time or more in the “push mode”.

  The performance processing unit 201 uses the sound generation setting data stored in the storage unit 4 to control the generation of the sound signal of the sound source 6 so as to generate sound corresponding to the key switch 100 on which the user has performed a performance operation. Specifically, the performance processing unit 201 performs tone specification on the sound source 6 with a predetermined initial tone color as initialization processing, and the note number corresponding to the Y coordinate of each switch in the note number table T with the above-described initial setting. Register.

  The performance processing unit 201 acquires the pressed key switch position information from the sub CPU 12 to detect the coordinates of the key switch 100 pressed by the user.

  The performance processing unit 201 refers to the note number table T to execute a sound generation process for specifying the note number corresponding to the notified coordinates and notifying the sound source 6. As a result, the sound source 6 generates a sound signal corresponding to the key switch 100 pressed by the user and having a set tone color.

  Based on the coordinates of the selection key switch 100 obtained by the performance processing unit 201, the display processing unit 203 executes processing (display processing) for controlling the light emission display of the corresponding light emission display unit 110.

  Here, the main CPU 2 measures the continuous pressing time of each key switch 100 based on the pressing information from the sub CPU 12. When the user continues to press the key switch 100 and the continuous pressing time exceeds a predetermined threshold time, the performance processing unit 201 and the display processing unit 203 are controlled to shift to the “push mode”.

  When the performance processing unit 201 detects the transition to the “push mode”, the performance processing unit 201 reads the effect information from the storage unit 4 and effects the sound generation data in time series. The effected pronunciation data is given to the sound source 6. Here, as this effect, for example, a process of gradually changing the pitch, gradually changing the sound length, gradually changing the volume, i.e., frequency modulation, repetitive period change, amplitude change, etc. It is a process to be executed.

  By such processing, it is possible to obtain a great variety of continuous pronunciation data according to the pressing time of the user. Then, by continuing to press down a plurality of key switches, it is possible to easily obtain musical data having a greater variety, high taste, and high degree of freedom. At this time, it is not necessary for the plurality of key switches to have the same pressing start time. If the pressing start times are different, a wider variety of musical tone data can be obtained. The effect information may be the same for all the key switches, but the degree of freedom of the musical sound data is further improved by making the information different.

  When the display processing unit 203 detects the shift of the “push mode”, the display processing unit 203 reads the light emission pattern from the storage unit 4 and controls the light emission display unit 110 corresponding to the light emission pattern.

  FIG. 8 is a diagram showing a light emission pattern of the matrix display input unit 9 in the push mode, where (A) shows the push mode start (one point press), and (B) shows the press point changes to two points for a predetermined time. Indicates the time that has elapsed.

  First, when the display processing unit 203 detects the shift of the “push mode” at a specific key switch 100A, the light emission of the key switch 100A that the user presses with the finger 901 as shown in FIG. From the state where the display unit 110A emits light, light emission control is performed in a predetermined area including the surrounding light emitting display unit 110B. At this time, the light emission display portion 110A of the push key switch 100A that originally emits light increases the light emission intensity with the elapsed time.

  Next, when the display processing unit 203 detects the shift of the “push mode” with another key switch 100C, the light emission of the key switch 100C that the user presses with the finger 902 as shown in FIG. 8B. From the state where the display unit 110C is caused to emit light, light emission control is performed in a predetermined area including the surrounding light emitting display unit 110D. At this time, the range of the light emitting display portion 110B around the light emitting display portion 110A is further expanded.

  As described herein, the light emission pattern is not limited to the one that gradually becomes stronger and wider, but the one that gradually becomes weaker, the one that is gradually weakened, and the light emission range can be made wider or narrower.

  By such processing, various light emission patterns can be obtained according to the pressing time of the user. Further, by continuing to press down a plurality of key switches, it is possible to easily obtain a light emission pattern that is more diverse, more interesting, and has a high degree of freedom.

  Thereby, the user can perform not only audibly fun but also very visually.

  Next, the operation process of the performance device of this embodiment will be described.

  FIG. 9 is a flowchart of the push mode process of the performance device of this embodiment.

  When the user continues to press the predetermined key switch 100 as described above, the sub CPU 12 of the matrix display input unit 9 sets the corresponding key switch 100 to the selected state, and displays the coordinate information corresponding to the selected key switch 100. This is given to the main CPU 2 (S11 → S12 → S13).

The performance processing unit 201 obtains sound generation data corresponding to the corresponding key switch 100 and generates a sound, and the display processing unit 203 performs normal strong light emission processing on the corresponding light emission display unit 110 (S14).
At this time, the main CPU 2 counts the pressing time using the timer 13 (S15).

  When the measurement pressing time exceeds a predetermined threshold Tth (S16), the main CPU 2 switches to the “push mode”, the performance processing unit 201 effects the sounding data (S17), and the display processing unit 203 has a predetermined light emission pattern. Light emission control is performed (S18).

  Such processing is continued until the corresponding key switch 100 is released (S18 → S11 → S12).

  By performing such a configuration and processing, the user can easily compose a musical sound with a high degree of preference and a high degree of freedom, and a display pattern with a high degree of freedom and a high degree of freedom can be easily created. Can get to.
