DETAILED DESCRIPTION OF THE INVENTION
  FIG. 1 is a block diagram showing a main configuration of a karaoke system 1 according to an embodiment of the present invention. The karaoke system 1 has a control means 10 that controls the operation of the entire system. The control means performs various functions by executing programs stored in the ROM 11. The RAM 12 is used for temporarily storing various data during program execution. The HDD 13 stores song data for the karaoke system 1 to perform karaoke performance. The song data includes performance data (MIDI data) that is information for performing the song, image data that is information for selecting an image to be displayed on the monitor in accordance with the song, and synchronization with the performance of the song. It contains lyrics data, which is information about the lyrics telop displayed on the monitor.
[0017]
  An operation means 14 is connected to the control means 10. The operation means 14 is provided with various operation members for the user of the karaoke system 1 to input a requested song or to apply various effects (echo, transposition, tempo change) to the song being played. . The operating means 14 has receiving means for receiving a signal from a remote controller (remote controller) 15. The remote control 15 also has various operation members similar to the operation means 14, and the user can freely operate the karaoke system 1 with the operation means 14 or the remote control 15.
[0018]
  Of the music data read from the HDD 13 at the request of the user, performance data, that is, MIDI data is sent to the performance control means 16. The performance control means 16 incorporates a MIDI sound source chip, reproduces the requested music piece based on the MIDI data, and outputs an audio signal to the amplifier 17. As will be described in detail later, the display control means 20 changes the display content of the monitor 21 based on the program change command in the MIDI data.
[0019]
  The amplifier 17 synthesizes the audio signal input by the performance control means 16 and the audio signal of the user's singing voice input from the microphone 18, amplifies it, and outputs it as an audible sound from the speaker 19.
[0020]
  The background moving image playback device 22 is, for example, a video CD playback device, and is configured to selectively play back a plurality of genre videos. The control means 10 controls the background moving image playback device 22 based on the image data of the song data, and plays back a moving image of a genre corresponding to the image data. The video signal output from the background moving image playback device 22 is input to the display control means 20.
[0021]
  The display control means 20 generates image data of the lyrics telop to be displayed on the monitor 21 based on the lyrics data in the song data. And the video signal which synthesize | combined the background image sent from the background moving image reproduction | regeneration apparatus 22 and the image of a lyrics telop is output.
[0022]
  In the karaoke system 1 of the present embodiment, the display control means 20 further selects the instrument for each channel based on the instrument number set for each MIDI channel indicated by the MIDI data (performance data) program change command. The image shown is generated and combined with the background image and the lyrics telop image.
[0023]
  FIG. 2 shows a state in which the icon 21A of the instrument set to the MIDI channel is displayed simultaneously with the normal karaoke screen (background image, lyrics telop). Note that not all musical instruments of the MIDI channel but musical instruments corresponding to three channels are displayed in the example of FIG. The number of musical instruments to be displayed is not limited to this example, and may be set as appropriate according to the size of the icon, the screen size, and the like. In this embodiment, the musical instrument is displayed as an icon. However, the musical instrument name is not necessarily an icon, and other forms such as a musical instrument name may be used.
[0024]
  In the karaoke system 1 of the present embodiment, the operation of the instrument icon display executed by the control means 10 will be described with reference to FIG. In S1, the control means 10 determines whether or not a performance request has been generated, that is, whether or not the user's requested song has been input. If a performance request has not occurred (S1: NO), a standby state is made in which the determination of S1 is repeated. When there is a user request, a performance request is generated (S1: YES), and the process proceeds to the performance process after S3. In the following description, only display of musical instruments based on MIDI data will be described. The performance based on the MIDI data, the display of the background image, and the display of the lyrics telop are the same processes as in the prior art. However, as will be described later, when the musical instrument being played is changed, a musical instrument change command (program change command) is transmitted to the sound source chip of the performance control means 16 by interrupt processing.
[0025]
  In S3, the control means 10 sequentially reads the MIDI data from the first command. The MIDI data to be referred for displaying the musical instrument is a note on command, a note off command, and a program change command. FIG. 4 shows the data structure of the note-on command, and FIG. 5 shows the data structure of the program change command.
[0026]
  The program change command is a command for instructing which musical instrument sound color is assigned to the MIDI channel. That is, the program change command includes data specifying a channel and data indicating an instrument number set for the specified channel.
[0027]
  The note-on command is a command that indicates which sound is played by an instrument set to a certain channel with what strength. As shown in FIG. 4, it is composed of data specifying a channel, data indicating which sound is played (note number), and data corresponding to intensity (velocity).
[0028]
  Although not shown, the note-off command is a command that specifies which sound of which channel is to be stopped, and is composed of data specifying a channel number and a note number.
[0029]
  In S5, the control means 10 determines whether or not the MIDI data is a program change command. If it is a program change command (S5: YES), since it has MIDI channel and instrument number data, in S7, an instrument number is set in a channel table which is a correspondence table of MIDI channels and instrument numbers. The channel table is stored in the RAM 12.
[0030]
  If the MIDI data read in S3 is a note-on command, NO is determined in S5 and YES is determined in S9. In this case, since the sound of the instrument of the channel specified by the note-on command is played, the instrument icon 21A of the channel set in the channel table in S11 is displayed on the monitor 21. . The image data of the musical instrument icon is stored in advance in a memory (not shown) inside the display control means 20.
[0031]
  If the MIDI data read in S3 is note-off data, NO is determined in S5 and S9, and YES is determined in S13. In this case, the instrument icon 21A of the channel specified by the note-off command is deleted from the monitor 21.
[0032]
  In the above, in order to simplify the flowchart, the note-off command is used to immediately erase the icon of the instrument of the channel. However, in practice, a plurality of notes on the same channel are simultaneously turned on. There is a possibility. In this case, if at least one note is in the on state, the instrument icon is displayed as it is even if the note-off command is detected in S13. In some cases, the velocity of the note-on command is set to 0 (zero) instead of the note-off command. In this case, the note-on command is substantially the same as the note-off command, and the above-mentioned case (when the velocity data of the note-on command is zero) is also used as the note-off command in the determination of S13. Shall be included.
[0033]
  If the MIDI data is a command other than a note-on command, a note-off command, or a program change command (if NO is determined in S5, S9, S13), the instrument display is not affected. In particular, control for display is not executed. In S17, it is determined whether the MIDI data is the last data. If the MIDI data is not the last data (S17: NO), the processing from S3 is repeated. If the MIDI data is the last data, all the musical instrument icons 21A displayed on the monitor 21 are deleted in S19, and the process returns to S1.
[0034]
  With the above processing, the icon of the instrument of each MIDI channel is displayed on the monitor 21 only when the instrument is being played. For this reason, the user can confirm the musical instrument which is performing the karaoke music both auditorily and visually. At this time, since the musical instrument icon is displayed by being combined with the normal karaoke background image and the lyrics telop, the musical instrument can be confirmed without interrupting the karaoke performance.
[0035]
  In the karaoke system 1 of the present embodiment, in addition to the display of the instrument icon for each MIDI channel, the user can freely change the instrument of each MIDI channel (the instrument set by the MIDI data). it can. This will be described with reference to the flowcharts of FIGS.
[0036]
  The musical instrument is changed by operating a key provided on the operation means 14 or the remote controller 15. In the following description, a method of changing a musical instrument by operating keys provided on the remote controller 15 will be described. As described above, since the operation member 14 is provided with the same operation member as the remote control 15, it is also possible to operate the operation member provided on the operation means 14 in the same manner as described for the remote control 15 below. It is possible to change the instrument.
[0037]
  FIG. 8 shows a key arrangement of the remote controller 15. The remote controller 15 is provided with a key 15K for selecting a normal karaoke song and performing various effects (echo, transposition, song interruption, etc.) during performance. A display device 15M for confirming the operation of the key 15K is also provided.
[0038]
  Further, the remote controller 15 is provided with keys for changing the musical instrument, in addition to the keys 15K. The keys for changing the instrument are a change key 151, a selection key 152, a cancel key 153, a <key (left shift key) 15L, a> key (right shift key) 15R, a △ key (up shift key) 15U, and a ▽ key. (Down movement key) 15D.
[0039]
  The musical instrument change is started by operating the change key 151 when the performance of the karaoke song is started and the musical instrument is displayed on the monitor 21. When the change key 151 is pressed, interrupt processing for changing the instrument shown in FIGS. 6 and 7 is executed. That is, when the change key 151 is pressed, the operation mode of the karaoke system 1 is switched to the musical instrument change mode.
[0040]
  When the change key 151 is pressed and the interrupt process of FIG. 6 is started, in S21, musical instruments that are candidates for musical instrument change are displayed at predetermined positions on the monitor 21, as indicated by 21B in FIG.
[0041]
  After displaying the candidate musical instrument icon 21B in S21, the control means 10 determines whether or not the cancel key 153 is pressed. When the cancel key 153 is pressed (S23: YES), the display of the candidate instrument icon 21B is erased in S61, the interruption process is terminated, and the normal karaoke performance mode is restored.
[0042]
  If the cancel key 153 has not been pressed (S23: NO), the instrument icon 21A set for the selected channel number is blinked in S27. When this interrupt process is executed, a predetermined MIDI channel, for example, channel 1 is selected as an initial value. In the example of FIG. 10, the whistle icon displayed on the leftmost side of the icon 21A is displayed blinking.
[0043]
  The user can change the musical instrument indicated by the blinking icon. That is, in the state of FIG. 10, the whistle can be changed to another musical instrument. To change the icon (piano) displayed on the right side instead of the whistle or the icon (guitar) displayed on the right side to another instrument, the blinking position is moved with the <key 15L or> key 15R. be able to. In FIG. 10, if the> key 15R is pressed once, the center icon of the three icons 21A is selected and blinks. If the> key 15R is pressed again, the rightmost icon (guitar) can be blinked.
[0044]
  That is, if the control means 10 determines that the> key 15R has been operated in S29 of the flowchart of FIG. 6 (S29: YES), the channel number is incremented in S31. Here, if the channel numbers corresponding to the three icons 21A are incremented by 1 in the order of, for example, channel 1, channel 2, and channel 3, the process of S31 increments the channel number by 1. If they are not arranged side by side (for example, in the case of an arrangement of channel 1, channel 4, and channel 10 or an arrangement of channel 1, channel 7, and channel 4), the icons 21A are sequentially displayed from left to right in the order of the arrangement. The channel number shall be changed so that it is selected. When the channel number is changed in S31, the process returns to S23, and the icon of the newly selected instrument flashes unless the cancel key 153 is pressed (that is, as long as NO is determined in S23) ( S27).
[0045]
  Although omitted in the flowchart, when the> key 15R is operated again while the icon displayed on the rightmost side is selected with the> key 15R, the leftmost side of the icon 21A is selected. In this way, the selection position circulates.
[0046]
  When an icon is selected by operating the <key 15L in S33, the channel number is decremented so that the icon displayed on the left side of the currently selected icon blinks, as in the case of the> key 15R. Also in this case, although not shown, when the <key 15L is operated with the leftmost icon selected, the rightmost icon 21A is selected.
[0047]
  After the icon of the instrument to be changed is selected by the above operation, a loop is constituted by S23, S27, S29, S33 and S37, and the selected icon continues to blink. Here, in order to set which instrument to change to, the △ key 15U or the ▽ key 15D is operated.
[0048]
  When the Δ key 15U or the ▽ key 15D is operated (S37: YES), the control means 10 advances the process to S41 (FIG. 7). In S41, a predetermined icon is selected from the musical instrument icons 21B that are candidates for change. For example, the leftmost icon 21B is selected as the initial value. Next, the selected icon is displayed blinking (S43). As in the case of selecting the icon 21A, the left or right adjacent icon of the selected icon 21B is selected by the operation of the <key 15L and> key 15R (S45: YES, S47; or S49: YES). , S51). When an icon is newly selected, the icon selected in S43 is blinked. When the selection of the icon is completed, a loop is formed by S43, S45, S49, S53, S55, and S57, and the selected icon continues to blink. In FIG. 11, as an example, the musical instrument icon (guitar) displayed on the right among the musical instruments being played and the second icon (trumpet) from the right among the musical instrument icons 21B to be changed are selected. It shows how it is.
[0049]
  Here, if the Δ key 15U or the ▽ key 15D is operated (S53: YES), the process returns to S23 in FIG. 6, and the currently used instrument selection process can be redone. If the cancel key 153 is operated in S55, the icon display of the candidate musical instrument is stopped in S61, and the interrupt process is terminated.
[0050]
  After selecting the instrument currently in use, if a candidate instrument is selected and it is determined in S57 that the selection key 152 has been pressed (S57: YES), the instrument number representing the candidate instrument indicated by the selected icon 21B is selected. The channel table corresponding to the icon 21A is set, and a program change command is transmitted to the sound source chip of the performance control means 16 (S59). Then, the icon 21B of the candidate musical instrument is deleted from the monitor 21, and the interrupt process is terminated.
[0051]
  When the instrument number of the newly selected instrument is input to the channel table, an instrument icon corresponding to the newly input instrument number is displayed in S11 of the process of FIG. In addition, since the program change command is transmitted to the sound source chip in the performance control means 16 in synchronization with the new instrument number stored in the channel table, not only the icon but also the sound to be played is updated. The sound of the instrument input in is reflected. When the selection key 152 is pressed in the example of FIG. 11, the icon of the guitar currently being played changes to a trumpet icon, and the guitar part is played as the trumpet part.
[0052]
  In the karaoke system 1 described above, the processing of S7 of FIG. 3 executed by the control means 10 constitutes the musical instrument type acquisition means according to claim 1, and is executed by the display control means 20 and the control means 10. The processing of S11 in FIG. 3 corresponds to the display control means according to claim 1. The monitor 21 constitutes the display means described in claim 1. Further, the remote control 15, the operation means 14, the control means 10, the performance control means 16, and particularly the processing shown in FIGS. 6 and 7 executed by the control means 10 constitutes the changing means according to claim 4. . Further, the process of S21 and the display control means 20 executed by the control means 10 constitute the second display control means.
[0053]
  The operation means according to claim 7 is constituted by the remote control 15 and the operation means 14 of FIG. 1, and in particular, from the <key 15 L,> key 15 R, Δ key 15 U, ▽ key 15 D, and selection key 152 on the remote control 15. Composed.
[0054]
  In the above-described embodiment, the selection state is indicated by blinking of the icon. However, a cursor or the like is displayed, a predetermined display area including the selected icon is highlighted, or the selected state is selected. Various methods such as changing the color of the icon can be adopted.
[0055]
  In the above embodiment, the candidate musical instruments are displayed and a desired instrument is selected from the candidate musical instruments. However, after selecting the icon to be changed from the icon 21A without displaying the candidate musical instruments, A method of changing the icon selected in response to the operation of the △ key 15U or the ▽ key 15D to another icon is also possible. In this case, although a list of candidate musical instruments cannot be obtained, it is possible to select musical instruments from a large number of candidates regardless of the screen size.
[0056]
  In addition, the musical instrument being used and the candidate musical instrument may be selected not only by the icon but also by characters or numbers. The feature of the present invention is that the user can operate the performance and can easily confirm the operation content visually. FIG. 12 shows the change of the tempo visually in addition to the display of the musical instrument icon 21A being played. Although it has been possible to change the tempo of the song being played, in the present embodiment, when the tempo change key of the keys 15K of the remote controller 15 is operated, the tempo corresponds to the tempo as shown in FIG. The graph 21C and a numerical value indicating that the tempo is 88 beats per minute are displayed on the monitor 21. The length of the graph 21C and the numerical value 88 change as the tempo changes. When the tempo change is completed, these indications disappear.
[0057]
  In this way, the tempo setting can be changed while checking information on the tempo displayed on the monitor 21. For example, if a user remembers a tempo when a song is sung as a numerical value, it is always accurate. You can set the tempo to sing the song. This applies not only to tempo but also to transposition. If you know how much to transpose when you sing a song with the information displayed on the screen, you can enjoy karaoke from the next time, when you sing that song, surely transpose to a key that is easy to sing. .
[0058]
  Although an example of changing the tempo is shown in FIG. 12, not only the tempo but also transposition can be displayed in a graph, and the change can be performed more easily and reliably.
[0059]
  In the karaoke system 1 configured as described above, the musical instrument being played can be recognized not only as a sound but also as an image. In particular, if the image is an icon indicating a musical instrument, it is possible to intuitively grasp the musical instrument. Note that since the instrument type is acquired based on the MIDI data, an accurate instrument type can be acquired. In addition, the change of the musical instrument and the change of the tempo may be performed during the performance of the karaoke song, or the performance may be interrupted. In general, since it is desirable not to disturb the performance, it is preferable to perform a setting change interrupt process while continuing the performance.
[0060]
  Furthermore, according to the karaoke system 1 described above, it is possible to change the musical instrument being played, and it is possible to reproduce a karaoke performance rich in change while using the same song data. Here, since the candidate musical instrument to be changed is also displayed as an image, the user can easily select the changed musical instrument. In particular, when an image of a musical instrument that can be replaced with a musical instrument being played is an icon indicating the shape of the musical instrument, the musical instrument can be selected more easily.
[0061]
  It should be noted that the icon of the musical instrument image that can be replaced with the musical instrument being played is displayed in a list on the screen of the display device and selected from the list, so that it is easy to determine a candidate musical instrument and the operation is simple. .
[0062]
