  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an electronic music apparatus according to an embodiment of the present invention.

  As shown in the figure, the electronic music apparatus of the present embodiment includes a performance operator 1 including a keyboard for inputting performance operation information such as sounding timing and pitch, and a plurality of information for inputting various information. A setting operation element 2 including switches and joysticks, a touch panel 3 for inputting various types of information including musical tone control information, and displaying various information, and a detection circuit for detecting an operation state of the performance operator 1 4, a detection circuit 5 that detects an operation state of the setting operator 2, a detection circuit 6 that detects a pressing operation such as an operation position or an operation pressure on the touch panel by a user, and a type and value of musical tone control information are input. A display circuit 7 for displaying various information including a GUI for displaying on the touch panel 3, a CPU 8 for controlling the entire apparatus, a control program executed by the CPU 8, and various table data. ROM 9 for storing data, RAM 10 for temporarily storing music data, various input information, calculation results, etc., timer 11 for measuring interrupt time and various times in timer interrupt processing, and various applications including the control program An external storage device 12 for storing programs, various music data, various data, and the like, a MIDI interface (I / F) 13 for inputting an external MIDI message and outputting a MIDI message to the outside, and a communication network 101 For example, a communication interface (I / F) 14 for transmitting / receiving data to / from a server computer (hereinafter abbreviated as “server”) 102, performance data input from the performance operator 1, or preset data A tone generator circuit 15 for converting music data into an audio signal; An effect circuit 16 for imparting various effects to the audio signal from the sound source circuit 15 and an audio signal from the effect circuit 16 are converted into sound, for example, a DAC (Digital-to-Analog Converter), an amplifier, a speaker, etc. And the like sound system 17.

  The above components 4 to 16 are connected to each other via a bus 18, a timer 11 is connected to the CPU 8, another MIDI device 100 is connected to the MIDII / F 13, and a communication network 101 is connected to the communication I / F 14. Are connected to the sound source circuit 15, and a sound system 17 is connected to the effect circuit 16. Here, the communication I / F 14 and the communication network 101 are not limited to the wired system but may be a wireless system. In addition, both types may be provided.

  Examples of the external storage device 12 include a flexible disk drive (FDD), a hard disk drive (HDD), a CD-ROM drive, and a magneto-optical disk (MO) drive. As described above, the external storage device 12 can also store a control program to be executed by the CPU 8. If the control program is not stored in the ROM 9, the external storage device 12 stores the control program. By reading it into the RAM 10, it is possible to cause the CPU 8 to perform the same operation as when the control program is stored in the ROM 9. In this way, control programs can be easily added and upgraded.

  FIG. 2 is a diagram showing a data format of the position information group stored in the position information group storage area 10 a secured at a predetermined position in the RAM 10.

  The position information group storage area 10a has a predetermined time nT (where “n” is a predetermined integer value, “T” is a period for detecting position information, and “nT” is 1 second, for example) It is formed by a ring buffer that holds a certain amount of position information group.

  The position information group includes an X coordinate value and a Y coordinate value of the position on the touch panel 3 (strictly, a musical tone control information control unit 3a described later with reference to FIG. 3) detected in the detection cycle T, and this position ( (The X coordinate value and the Y coordinate value) and the previously detected position (the X coordinate value and the Y coordinate value) and a plurality of sets of positional information including the movement speed and the elapsed time (a set of positional information). = N + 1) sets of position information.

  As will be described later with reference to FIG. 9, the latest set of position information (current position information) is detected and calculated every predetermined time T and stored in a predetermined position of the position information group storage area 10a. The X coordinate value and the Y coordinate value of the current position are usually the X coordinate value and the Y coordinate value of the position on the musical tone control information control unit 3a pressed by the user, but the user presses the musical tone control information control unit 3a. Since the current position may automatically move from the pressed position to the predetermined position when the operation is stopped, the X coordinate value and the Y coordinate value of the current position are the same as the X coordinate value and Y of the predetermined position. Coordinate value.

  The control process executed by the electronic music apparatus configured as described above will be described first with reference to FIGS. 3 and 4 and then in detail with reference to FIGS.

  FIG. 3 is a diagram illustrating an example of a screen displayed on the touch panel 3 when the touch panel 3 is used as a device for controlling two types of musical tone control information values of pitch bend and modulation depth.

  As shown in the figure, a musical tone control information control unit 3a composed of a secondary plane is provided on the touch panel 3, and an X axis and a Y axis are defined on the musical tone control information control unit 3a. The X-axis and Y-axis can be assigned different types of musical tone control information. In the example of FIG. 3, a modulation depth is assigned to the X-axis and a pitch bend is assigned to the Y-axis. Yes. When the type of musical tone control information assigned to each axis is determined, the default value is automatically set as the initial value (maximum value and minimum value) of the musical tone control information value. The initial value can be freely changed by the user as will be described later with reference to FIG.

  When the user performs a sliding operation on the musical tone control information control unit 3a using, for example, his / her finger F, the current position C on the musical tone control information control unit 3a is displayed with a “+” mark, and the sliding operation is performed. The locus from the start position S to the current position C is displayed in a predetermined display mode. Here, the trajectory display is performed based on the position information group stored in the position information group storage area 10a. Therefore, strictly speaking, the start point S of the trajectory corresponds not to the start position of the sliding operation but to the position of the set of position information stored the oldest in the position information group. Of course, if the sliding operation time is within the predetermined time nT (1 second in the present embodiment), the start point S of the locus coincides with the starting position of the sliding operation. Further, the predetermined display mode is, for example, a color corresponding to a thickness corresponding to an elapsed time and a moving speed. In the example of FIG. 3, the shape of the trajectory is displayed thicker as it approaches the current position C, but its color has not changed. This is because the drawing cannot be colored. Actually, a touch panel 3 that can be displayed in color is adopted, and the locus is colored according to the moving speed of the sliding operation. As the coloring mode, for example, a mode in which the color intensity is changed or the color itself is changed can be considered. When the aspect of changing the color intensity is adopted, a monochrome display touch panel may be adopted instead of the color display touch panel 3 as long as gradation display is possible. As described above, in this embodiment, the display mode of the trajectory is changed according to the elapsed time and the moving speed. Therefore, the elapsed time and the moving speed are included in the set of position information constituting the position information group. ing. Note that a plurality of selectable display modes may be prepared in advance so that the user can select from among them. By doing in this way, the freedom degree of the display mode of a locus can be raised. Specifically, the trajectory can be displayed in a user's favorite display mode, such as a trajectory having a constant thickness regardless of the passage of time or a trajectory having a constant color regardless of the moving speed.

  In the present embodiment, external performance information is input, musical tone control information included in the external performance information is acquired, and the acquired musical tone control information is assigned to the X axis and Y axis of the musical tone control information control unit 3a. If so, the trajectory can be displayed on the musical tone control information control unit 3a. In the example of FIG. 3, the trajectory from the starting point S ′ to the current position C ′ corresponds to the trajectory of the musical tone control information acquired from the external performance information. Here, as the external performance information, specifically, the performance information input from the MID II / F 13 from the other MIDI device 100 and the performance data stored in the external storage device 12 are reproduced. The performance information generated by can be listed. Note that the musical tone control information acquired from the external performance information is an area on the RAM 10 different from the position information group storage area 10a, but an area (not shown) having the same data format as the position information group storage area 10a. The locus from the starting point S ′ to the current position C ′ is displayed in a predetermined display mode based on the position information group stored in this area.

  Depending on the selected musical tone control information and the user's preference, it may be better not to display the trajectory. In this embodiment, it is possible to select whether or not to display the trajectory. Further, the user may be able to select whether or not to display the locus of the musical tone control information acquired from the external performance information.

  FIG. 4 is a diagram illustrating an example of a screen displayed on the touch panel 3 when the touch panel 3 is used as a device for controlling two types of musical tone control information values of pitch bend and brightness.

  The display example of FIG. 4 differs from the display example of FIG. 3 in that the minimum value of the musical tone control information (pitch bend) assigned to the Y axis, the type of musical tone control information assigned to the X axis (brightness), and the user's musical tone. The difference is that the finger F is separated from the musical tone control information control unit 3a after the sliding operation on the control information control unit 3a. Due to this difference, first, the display position and display mode of the X axis and the Y axis are different. Next, when the user removes the finger F from the musical tone control information control unit 3a after the sliding operation, the current position C moves to a predetermined position C ″ at a constant speed and stops. The pitch bend is normally controlled by an operator called a pitch bend wheel, and the user releases the hand from the pitch bend wheel. This is because the pitch bend wheel automatically returns to the initial state when the is not operated, and the pitch bend is not controlled. Therefore, in the illustrated example of FIG. 4, the value of the Y coordinate (= pitch bend value) is changed to a predetermined value without changing the value of the X coordinate (= brightness value). Of course, as with the pitch bend, if the musical tone control information of the type that returns to the initial state when not operated is assigned to the X axis, the X coordinate is also changed to a predetermined value in the same manner as the Y coordinate. That's fine. On the other hand, if musical tone control information of a type that does not need to be returned to the initial state even when no operation is performed is assigned to the Y coordinate, the Y coordinate is also slid like the X coordinate. What is necessary is just to maintain the state which finished dynamic operation.

  As can be seen by comparing FIG. 3 and FIG. 4, the “+” mark is displayed enlarged when the musical tone control information control unit 3 a is pressed rather than when it is not pressed. This is because if the “+” mark remains small, the “+” mark is hidden by the finger F, and it is difficult for the user to know where the musical tone control information control unit 3a is pressed.

  The musical tone control information assigned to the X axis and Y axis of the musical tone control information control unit 3a is preferably of a type having continuous values, such as MIDI control change, parameter control, pitch bend, and the like. This is because binary information such as note on / off has little meaning to display the locus. However, even if the tone control information is of a kind having discrete values, it is also possible to assign it to the X axis and the Y axis of the tone control information control unit 3a if it is meaningful to display the trajectory.

  Next, this control process will be described in detail.

  FIG. 5 is a flowchart showing a procedure of a main routine executed by the electronic music apparatus of the present embodiment, particularly the CPU 8. This main routine is started and executed in response to a timer interrupt that occurs every time the timer 11 times a predetermined time (for example, 3 msec).

This main routine
(1) Performance operation processing for generating musical sounds according to performance operators operated by the user (step S1)
(2) Musical sound control information selection processing for assigning the musical sound control information selected by the user to the X axis and Y axis of the musical sound control information control unit 3a (step S2)
(3) Range setting process for setting the range of the musical tone control information assigned to the X axis and the Y axis of the musical tone control information control unit 3a (step S3)
(4) Current position processing for performing processing related to the current position on the musical tone control information control unit 3a (step S4)
(5) Trajectory processing for displaying the trajectory of the current position on the musical tone control information control unit 3a (step S5)
(6) External performance information processing for displaying a trajectory based on musical tone control information acquired from external performance information (step S6)
It is mainly comprised by. In the present embodiment, the processes (4) to (6) are executed every timer interrupt, that is, every 3 msec. However, when the locus need not be displayed with high accuracy (the period T = 3 msec) may be executed every predetermined number of timer interruptions. Hereinafter, each process of (1)-(6) is demonstrated in order.

  FIG. 6 is a flowchart showing a detailed procedure of the performance operation process (1).

  As shown in the figure, (1) in the performance operation process, when the keyboard of the performance operator 1 is operated, in particular, the operation event data corresponding to the operated key, specifically, the pressing of the operation event data. Operation event data including key code data corresponding to the pitch of the key and key, velocity data corresponding to the key depression, and key-on data is generated, and the operation event is transmitted to the sound source circuit 15, whereby the operation from the sound source circuit 15 is performed. Generates a tone signal according to the event. As a result, the operation on the performance operator 1 is reflected in the musical tone generation (steps S11 → S12).

  FIG. 7 is a flowchart showing a detailed procedure of the tone control information selection process (2).

  As shown in the figure, in (2) musical sound control information selection processing, when the user performs musical sound control information selection operation for the X axis or Y axis of the musical sound control information control unit 3a, first, the X axis or Y axis is selected. , A predetermined option, that is, a kind of selectable tone control information is presented to the user (steps S21 → S22). Here, the selection operation of the musical tone control information with respect to the X axis or the Y axis is specifically the display field 3bx or 3by for displaying the name of the musical tone control information assigned to the X axis or the Y axis in FIG. This is pressing the inside or the vicinity thereof with the finger F. Then, by this pressing operation, a pull-down menu (option) in which names of a plurality of musical sound control information that can be selected on the axis are displayed below the display column 3bx or 3by. Of course, the selection operation method and the option presentation method are merely examples, and other methods may be adopted.

  When the user selects any tone control information from this pull-down menu, the selected tone control information is assigned to the corresponding axis, and the range of the tone control information, that is, the maximum value and the minimum value is set to the initial value. It is set (step S23). In the present embodiment, as described above, the initial value of the range is set by default for each musical tone control information, so if the type of musical tone control information is determined, the initial value is uniquely determined, and this initial value is Set automatically. Of course, not limited to this, the user may arbitrarily determine the initial value of the musical tone control information.

  Then, the value (current value) of the selected tone control information is acquired for the X axis or the Y axis, and the position on the touch panel 3, that is, the position on the tone control information control unit 3a is calculated and held (step S24). ) After initializing the position information group storage area 10a (step S), the display on the touch panel 3 is updated (step S26).

  (2) According to the musical tone control information selection process, for example, when the user assigns a modulation depth to the X axis and a pitch bend to the Y axis, as shown in FIG. 3, the X coordinate display fields 3bx to 3dx “Modulation Depth”, “127”, and “0” are displayed, and “Pitch Bend”, “+2 oct (octave)”, and “−2 oct” are displayed in the Y coordinate display fields 3by to 3dy. Then, the display position and display mode of the X axis and Y axis are determined, and the X axis and Y axis are displayed in the determined display position and display mode. That is, in the example of FIG. 3, since the origin O of the XY coordinates is located at the center of the Y axis and is located at the end of the X axis, the origin O of the XY coordinates is close to the center of the left end of the tone control information control unit 3a. As shown, the X axis and the Y axis are displayed. Further, a “+” mark indicating the current position is displayed in a normal size at the calculated position on the musical tone control information control unit 3a.

  FIG. 8 is a flowchart showing a detailed procedure of the range setting process (3).

  This (3) range setting process is performed when the user performs a setting operation for setting (changing) the range of the musical tone control information currently assigned to the X axis or the Y axis, that is, the maximum value or the minimum value. It is activated and executed (steps S31 → S32). Here, the setting operation is the same as the selection operation described with reference to FIG. 7, that is, in the display column 3cx, 3cy, 3dx or 3dy of the maximum value or minimum value of the X axis or Y axis, or in the vicinity thereof. A pressing operation with the finger F may be performed.

  For example, when the user presses the display field 3 dy with the finger F, a pull-down menu (option) in which a plurality of values that can be set as the minimum value of “pitch bend” is displayed below the display field 3 dy (step) S32). When the user selects any value from the pull-down menu, the currently set minimum value (“−2 oct” in the example of FIG. 3) is changed to the selected value (step S33). If the user selects, for example, “−1 oct” as the minimum value of “pitch bend”, the minimum value of “pitch bend” is displayed as “−1 oct” as shown in FIG.

  Since the processes in steps S34 and S35 are the same as the processes in steps S25 and S26 in FIG.

  (3) According to the range setting process, the currently set range is changed to the range selected by the user, and the display of the range, the display position and display mode of the X axis and the Y axis are also changed accordingly. .

  FIG. 9 is a flowchart showing a detailed procedure of the current position process (4).

This (4) current position processing is
(A) Processing for generating information on the current position and storing it in the position information group storage area 10a (b) Generating an event of musical tone control information based on the generated information on the current position, and generating the sound source circuit 15 or effect circuit 16 is mainly configured by processing to be sent to 16.

  Then, the processing (a) and (b) when the musical sound control information control unit 3a is pressed with the finger F, and the processing (a) and (b) when the pressing is stopped, This is realized by one flowchart.

  When the musical tone control information control unit 3a is being pressed with the finger F, the CPU 8 first sets the pressed position as a target position (steps S41 → S42). Next, the CPU 8 determines the current position by approaching the target position with a predetermined time constant (following speed) (step S43). When the musical tone control information control unit 3a is pressed with the finger F, the target position and the current position are the same, so at this time, the CPU 8 determines the target position as it is (ie, without approaching with a predetermined time constant) as the current position. To do. Based on the difference Δx between the X coordinate value of the current position and the X coordinate value of the previous position and the difference Δy between the Y coordinate value of the current position and the Y coordinate value of the previous position, the CPU 8 calculate.

Movement speed = {(Δx) ² + (Δy) ² } ^1/2 / T
Here, “T” is the period.

  Next, the CPU 8 stores the X coordinate value and the Y coordinate value of the current position, the calculated moving speed, and the elapsed time “0” in the position where the latest information is stored in the position information group storage area 10a ( Step S45).

  Further, the CPU 8 converts the X coordinate value and the Y coordinate value of the current position into each value of the musical tone control information assigned to the X axis and the Y axis, and converts each value of the musical tone control information obtained by the conversion. The included event data is generated and transmitted to the tone generator circuit 15 or the effect circuit 16 (step S46). Here, the number and types of event data to be generated differ depending on the types of musical tone control information assigned to the X-axis and the Y-axis, and the generated event data may be transmitted to either the tone generator circuit 15 or the effect circuit 16. It depends on the type of musical tone control information assigned to the X axis and Y axis. The above-mentioned “generate event data and transmit it to the sound source circuit 15 or the effect circuit 16” means this.

  When the tone control information control unit 3a is pressed with the finger F and then stopped, that is, when the finger F is released from the tone control information control unit 3a, the tone control assigned to the X axis or the Y axis As described above, when the information is of a type returning to the predetermined position, the CPU 8 sets the predetermined return position as the target position (steps S41 → S47 → S48). Then, the CPU 8 determines the current position by approaching the target position with a predetermined time constant (following speed) (step S43).

  The subsequent processing is the same as the corresponding processing (steps S44 to S46) when the musical tone control information control unit 3a is pressed with the finger F, and the description thereof is omitted.

  FIG. 10 is a flowchart showing a detailed procedure of the trajectory process (5). This (5) trajectory process draws a trajectory on the musical tone control information control unit 3a described with reference to FIG. 3 and FIG. Processing is mainly performed.

  In FIG. 10, first, the CPU 8 displays a mark indicating the current position (“+” in the present embodiment) at the current position (step S51). In the present embodiment, since the shape of the “+” mark changes depending on whether or not the user is pressing the musical tone control information control unit 3a, the CPU 8 outputs the output from the detection circuit 6 in step S51. When the value is checked and the user is pressing the musical tone control information control unit 3a, the sign “+” is enlarged from the normal shape by a predetermined magnification and displayed.

  Next, if the setting for performing the trajectory display is selected (that is, if “YES” is displayed in the display field 3e for displaying whether or not the trajectory is displayed), the CPU 8 stores the position information group storage area 10a. Is set as a target of a process of drawing a trajectory one by one from the latest (elapsed time “0”) position information set to a position information set that is back by a predetermined time nT (for example, 1 second) (step S53 and S57), for each set of position information to be processed, a trajectory is sequentially drawn as follows. That is, the CPU 8 determines the thickness and the moving speed according to the elapsed time from the position to be processed (X coordinate value and Y coordinate value) to a position (X coordinate value and Y coordinate value) one (time T) backward. A trajectory is drawn in a color corresponding to the color (step S54). Then, the CPU 8 adds the predetermined time T to the elapsed time to be processed (step S55). In step S45 of the (4) current position processing, the latest current position is stored in the position information group storage area 10a with the elapsed time “0”. Therefore, among the position information groups stored in the position information group storage area 10a, Older sets of position information need to be made older by the period T. The process of step S55 performs this process, and is not directly related to the process of drawing a trajectory.

  (5) According to the trajectory process, a trajectory from the start position S to the current position C as shown in FIG. 3 or a predetermined position after the current position C has passed from the start position S as shown in FIG. The trajectory up to C ″ is drawn in the musical tone control information control unit 3a.
