  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 2 is a block diagram showing a hardware configuration of a personal computer as a performance program reproducing device provided with a tempo setting device according to an embodiment of the present invention. In FIG. 1, a personal computer (hereinafter referred to as “personal computer”) 1 includes a personal computer body 2, an input device 3 including a keyboard 3 a and a mouse 3 b, a display 4, a speaker 5, and a microphone 6. Note that the personal computer main body 2, the input device 3, the display 4, the speaker 5, and the microphone 6 may be independent from each other, or may be an integrated notebook personal computer or the like.

  The personal computer main body 2 includes a CPU 20, a ROM 21, a RAM 22, a CD-ROM driver 23 and a sound source 24, and an input / output interface 25. In the CPU 20, the sound source 24 is a sound device such as a MIDI sound source or a sound card. The input / output interface 25 includes an output terminal for the speaker 5 and also includes an input terminal for connecting the microphone 6. The automatic performance data and tempo setting program executed by the personal computer 1 are recorded on a CD-ROM as a recording medium, and are taken into the personal computer main body 2 using the CD-ROM driver 23.

  FIG. 1 is a block diagram showing the main functions of the tempo setting device. In the figure, a tempo setting device 7 has a tempo value input unit 8 and a performance start instruction unit 9 for manually starting a performance program. Further, a tap tempo input unit 10, an output selection unit 11, a tempo detection unit 12, and a tap end detection unit 13 for automatically starting a performance program are provided. Further, a tempo value setting unit 14 is provided as a common function for manual start and automatic start. The automatic performance unit 15 executes a performance program according to the tempo value set by the tempo setting device 7 to generate a musical sound.

  The manual start mode by the function shown in FIG. 1 will be described. The tempo value input unit 8 is a numeric keypad of the keyboard 3a, for example, and inputs the number of beats numerically. The beat value input from the tempo value input unit 8 is stored in the tempo value setting unit 14 secured in the RAM 22. The performance start instructing unit 9 is, for example, a return key (or other predetermined key) of the keyboard 3a. 15 reproduces a performance program that is on standby in the RAM 22 according to the tempo value read from the tempo value setting unit 14, and generates a musical sound from the speaker 5.

  Next, the automatic start mode by the function shown in FIG. 1 will be described. The tap tempo input unit 10 is, for example, a shift key (or other predetermined key) of the keyboard 3a. When a predetermined screen (described later) is displayed on the display 4, the tap tempo input unit 10 is pressed when the shift key is pressed a predetermined number of times. The number of tap signals corresponding to the number of times is input to the tempo detection unit 12. In the after-effect mode described later, the first tap signal may be input when the shift key is pressed once and then the pressed shift key is released. When the tap signal is input, the tempo detection unit 12 detects an input interval of the tap signal based on the reference clock, calculates a beat value per minute from the interval, and inputs the beat value to the tempo value setting unit 14. The tap end detection unit 13 inputs the tap end signal to the automatic performance unit 15 when a predetermined number of tap signals are detected.

  The output selecting unit 11 includes, for example, a selection button (described later) displayed on the display 4. The selection button determines the tempo in the output mode, or determines the tempo by three tappings and performs the third tapping. It is selected whether it is a double-starting mode for starting performance (a mode that starts in response to “high” of the “sun, high”). In the after-effect mode, the tempo detection unit 12 detects the input interval of the first and second tap signals and calculates the tempo value at the interval. Further, the tap end detection unit 13 outputs a tap end signal as soon as the second tap signal is input in the output mode, and immediately taps when the third tap signal is input in the pre-twist mode. Output an end signal.

  In the pre-paid twice mode, the tempo detection unit 12 calculates a tempo value by an average value of the input intervals of the first and second tap signals and the input intervals of the second and third tap signals. The calculated tempo value is input to the tempo value setting unit 14 and the tap end detection unit 13. Then, in the double-starting mode, the tap end detection unit 13 inputs a tap end signal to the automatic performance unit 15 when the third tap signal is input. When the tap end signal is input, the automatic performance unit 15 reproduces the performance program read into the RAM 22 and put into standby according to the tempo value read from the tempo value setting unit 14, and generates a musical sound from the speaker 5.

  Next, the operation of the tempo setting device 7 will be described in accordance with the flowcharts of FIGS. 3, 5, and 7 with reference to screen display examples of the display 4 shown in FIGS. In step S <b> 1 of FIG. 3, a start screen is displayed on the display 4. FIG. 4A is an example of a start screen, and a manual start mode button 41 and an automatic start mode button 42 are displayed on the display 4. The cursor 43 is placed on one of these buttons 41 and 42 and the mouse 3b is clicked to select a performance start mode. In the following description, the operation of moving the cursor to the icon on the screen and clicking the mouse 3b is described simply by turning “button” or “switch” “on”.

  In step S2, it is determined whether the manual start mode or the automatic start mode is selected depending on which of the buttons 41 and 42 is turned on. If it is the manual start mode, the process proceeds to step S3 and a tempo value input screen is displayed. FIG. 4B shows an example of a tempo value input screen, in which an input tempo value display frame 44, a message 45 “Please input tempo value”, and an input end button 46 are displayed.

  In step S4, it is determined whether a tempo value has been input. When a tempo value is input from the numeric keypad of the keyboard 3a, the input tempo value is displayed in the input tempo value display frame 44 in step S5. The input tempo value is stored in the buffer. In step S6, it is determined whether or not the end button 20 is turned on. If step S6 is positive, the process proceeds to step S7, and the input tempo value of the buffer is set in the tempo value setting unit 14.

  In step S8, a performance start instruction screen is displayed. FIG. 4C is an example of a performance start instruction screen, and a performance start button 47 is displayed. In order to execute the performance program, the performance start button 47 is turned on or the return key of the keyboard 3a is pressed.

  In step S9, it is determined whether or not performance is started. If the performance is started, the process proceeds to step S10, the tempo value is read from the tempo value setting unit 14, and the performance program is executed at the tempo to generate a musical sound. Note that the musical score may be displayed on the display 4 together with the musical sound. The performance process is well known and will not be described. Although explanation is omitted in the flowchart, if the delete button 26 is turned on in each screen of FIGS. 4 and 6, the screen returns to the previous screen.

  If it is determined in step S2 that the automatic start mode is selected, the process proceeds to step S11 (FIG. 5). In step S11, a selection screen for either the after-effect mode or the pre-paid twice mode is displayed. FIG. 6A is a display example of a selection screen for either the after-effect mode or the double-stroke mode, and the double-stroke mode instruction button 48 and the double-stroke mode button (Sun, high-direction button) 49 are displayed. Yes. When these buttons are turned on, the tap mode is selected depending on which is turned on. That is, the buttons 48 and 49 constitute the output selecting unit 11.

  In step S12, it is determined whether or not the tap mode is an after-effect mode. If the output instruction button 48 is turned on, the process proceeds to step S13 to display a tapping input instruction. FIG. 6B is an example of display of a tapping input instruction, in which a message 50 “Please tap for tempo setting” is displayed.

  In step S14, it is determined whether or not a predetermined operator (in this example, a shift key) has been pressed (tapping on). If tapping is on, the process proceeds to step S15 to determine whether or not the shift key is released (tapping off). If it is determined that the tapping is off, the process proceeds to step S16 to output a tap signal and start a timer for counting the tapping interval.

  In step S17, it is determined again whether tapping is on. If step S17 is affirmative, the number of beats (tempo value) per minute is calculated by the tempo detection unit 12 based on the count value of the tap interval timer in step S18, and set in the tempo value setting unit 14.

  In step S19, since tapping twice corresponding to the output by the operation of the shift key has been performed, the tap end detection unit 13 instructs the automatic performance unit 15 to start performance. In step S20, the automatic performance unit 15 reads the tempo value set by tapping from the tempo value setting unit 14, executes the performance program according to the tempo value, and generates a musical sound.

  On the other hand, if it is determined in step S12 that the mode is not the after-act mode, the process proceeds to step S21 (FIG. 7) for the pre-paid twice mode, and “3” is set to the count value C1 of the counter for the number of tappings. . In step S22, a display for prompting a tapping input instruction is performed. It is a display of FIG.6 (b). In step S23, it is determined whether or not the shift key is pressed (tapping on). If tapping is on, the process proceeds to step S24, and the count value C1 is decremented (-1).

  In step S25, a tap signal is output and a timer for counting the tapping interval is started. In step S26, it is determined whether tapping is on. If tapping is on, the process proceeds to step S27, and the count value C1 is decremented (-1). In step S28, the count value of the tap interval timer is calculated as the first time interval TEMPO1. In step S29, it is determined whether or not the count value C1 is “0”. Since the count value C1 is not “0” at first, the process proceeds to step S30. In step S30, the time interval TEMPO1 is written as TEMPO2 in the buffer, the process proceeds to step S31, the tapping interval timer is reset to “0”, and the process proceeds to step S25.

  When the third tapping-on is detected in step S26, the count value C2 is decremented in step S27 and the count value C1 becomes “0”. Therefore, the determination in step S29 becomes affirmative, and the process proceeds to step S32.

  In step S32, an average value of the time interval TEMPO1 and the time interval TEMPO2 is calculated and set as the time interval TEMPO. In this case, if the difference between the two is larger than the predetermined value, the time interval TEMPO1 detected later is weighted so that the average value does not deviate from the time interval TEMPO1.

  In step S33, the number of beats per minute (tempo value) is calculated by the tempo detection unit 12 based on the tap interval time TEMPO and set in the tempo value setting unit 14. In step S34, the tap end detection unit 13 instructs the automatic performance unit 15 to start playing because tapping has been performed a predetermined number of times (three times) in the two-stroke mode by operating the shift key. In step S35, the automatic performance unit 15 reads the tempo value from the tempo value setting unit 14, executes the performance program according to the tempo value, and generates a musical sound.

  As described above, according to this embodiment, when the tempo is recognized by a predetermined number of tappings, the performance starts immediately after the last tapping. Therefore, when the conductor calls out “Sun, high”, the voice can be uttered simultaneously with the sound of “high”. In addition, it is possible to start singing or performing with the performance method suitable for the general “outfact” in the command method, that is, with the voice of the conductor “high” only.

  In the present embodiment, the tempo value is calculated based on the time from when the key as the tap tempo input unit 10 is released (tapping off) to the next key pressing (tapping on) in the effect mode. However, this is an aftertact, and the tempo is determined by an operation similar to the operation of swinging the baton from the bottom to the top. A tempo value may be calculated. In short, it is only necessary that the performance can be started immediately after the final tapping is completed.

  In this embodiment, the tempo is set before the performance is started. However, a well-known tempo control method that can change the tempo can be used during the performance.

  This embodiment shows the best mode of the present invention and can be modified by those skilled in the art without departing from the present invention. For example, functions such as a performance start instruction button and a tap tempo input key can be assigned by arbitrarily selecting input means such as a keyboard and a mouse.

  Further, in this embodiment, the output selecting unit for selecting the output mode and the pre-paid twice mode is provided, but the tempo is fixedly determined in any one of these modes and the performance is started. Also good.

  Furthermore, in the present embodiment, description has been given of the case where either one of the after-act mode and the double-stroke mode can be selected. However, the present invention is not limited to this, and after calculating the tempo value at the interval between the two strike points. Further, a mode for starting performance after one beat according to the tempo value may be further provided, and this mode may be selected together with the after-act mode and the pre-pause twice mode.
