  The external input accepting unit 56 accepts input of audio information from an external device connected to the karaoke device 10. Preferably, input of audio information from an external device corresponding to a specified musical instrument (electric guitar 50 in the present embodiment) to be determined by the performance sound adding means 60 described later is received. For example, input of audio information (performance signal) from the electric guitar 50 as an external device connected to the audio processing unit 22 to the audio processing unit 22 via the sound effector 46 and the audio input terminal 44 is received. . The audio information received by the external input receiving means 56 is supplied from the audio processing unit 22 to the amplifier 38 via the audio output terminal 36 and amplified by the amplifier 38 as described above from a speaker (not shown). Is output. Here, the external input receiving means 56 may be provided in a control unit built in the sound effector 46. Further, the voice processing unit 22 may function as the external input receiving unit 56.

  The performance control means 52 includes minus one performance control means 54. The minus one performance control means 54, for example, when the input of audio information from the external device is received by the external input reception means 56, among the performance sounds of the musical instruments corresponding to the plurality of tracks in the music data, The minus one (N-1) performance control is executed to output the performance sound of the musical instrument corresponding to the other tracks without outputting the performance sound of the track corresponding to the specified musical instrument. For example, in the case where the input of audio information from the electric guitar 50 is received by the external input receiving means 56, the musical instrument data corresponding to the electric guitar 50 among the performance sounds corresponding to a plurality of tracks in the music data. The performance sound of the musical instrument corresponding to the remaining track is output without outputting the performance sound of the track (eg, track 3). In other words, the output of the music based on the music data is controlled on the assumption that there is no track corresponding to the electric guitar 50. At the time of performance control by the minus one performance control means 54, if the input of audio information from the external device is received by the external input receiving means 56, the audio information input from the external device is as if one part (external) As a part corresponding to the apparatus, it is possible to realize a karaoke performance as if a band performance was performed in accordance with the performance of the musical instrument corresponding to the remaining track.

  The output speed setting means 58 sets the output speed of the music data in the music performance control by the performance control means 52 (minus one performance control means 54). That is, the output speed of the performance sound output based on the music data is set. For example, the output speed of the music data is set according to the operation of a speed control knob (not shown) provided on the operation panel 24. In such a speed control knob, the output speed of the music can be set from, for example, a normal (default) performance speed of −90% to + 90% in increments of 10%, for example. In the performance control of the music piece by the performance control means 52 (minus one performance control means 54), the sound processing unit 22 outputs the music piece at an output speed corresponding to the operation position of the speed control knob at that time. The performance output based on the performance information (MIDI data) is controlled. That is, basically, the output speed is controlled based on the tempo determined on the conductor track of the MIDI data, and the output speed is changed (corrected) corresponding to the operation position of the speed control knob. In other words, the output speed setting means 58 controls (changes) the tempo of the music performance control by the performance control means 52 (minus one performance control means 54) according to the operation position of the speed control knob.

  When the output speed set by the output speed setting means 58 is slower than a predetermined threshold value, the performance sound adding means 60 is configured to output a performance sound of a predetermined specified instrument among the plurality of types of instruments. Between the adjacent output timings (beat timings), performance sounds of instruments different from the instrument are added at equal time intervals (equal intervals between beat timings). Preferably, when the output speed set by the output speed setting means 58 is slower than the threshold during performance control by the minus one performance control means 54, the performance sound set in advance in the MIDI data is recorded. Adjacent output timings of musical instrument performance sounds (not output during performance control by the minus one performance control means 54) corresponding to tracks that are not output (tracks excluded from the output target by the minus one performance control means 54) Between each other, performance sounds of different instruments are added at equal time intervals. The threshold value corresponds to an extremely slow speed such as a normal (default) performance speed of −50% to −90%, and is, for example, 1/2 of the default value.

  The additional musical instrument type determining means 62 determines an instrument corresponding to the performance sound added by the performance sound adding means 60. Preferably, the performance sound adding means 60 adds a musical instrument exclusively for taking a rhythm, such as “bass drum”, “snare drum”, and “hi-hat”, which are percussion instruments that cannot set the scale of the performance sound. It is determined as the instrument corresponding to the sound. Preferably, the performance sound added by the performance sound adding means 60 from a musical instrument having a corresponding track in the music data to which performance sound is added by the performance sound adding means 60 is used. Select the corresponding instrument. That is, any musical instrument having musical score information corresponding to a rhythm track (for example, track 10) is added by the performance sound addition means 60 in the music data to which performance sounds are added by the performance sound addition means 60. Select the instrument corresponding to the performance sound to be played. For example, in the case where musical score information corresponding to “bass drum”, “snare drum”, and “hi-hat” is defined in the rhythm track of the music data to which performance sound is added by the performance sound addition means 60. Any one of the “bass drum”, “snare drum”, and “hi-hat” is selected as an instrument corresponding to the performance sound added by the performance sound addition means 60. Preferably, the musical instrument corresponding to the performance sound added by the performance sound adding means 62 may be arbitrarily selected by the user from a plurality of types of musical instruments that can be set in the MIDI data. Good. For example, the musical instrument corresponding to the performance sound added by the performance sound adding means 60 may be selected by an input operation via a remote controller (not shown).

  The additional musical instrument type determining means 62 is preferably used in the musical composition data to which performance sound is added by the performance sound adding means 60 according to the type of musical instrument (having corresponding musical score information). The musical instrument corresponding to the performance sound added by the performance sound addition means 60 is selected. For example, when “bass drum” is not used in the music data to which the performance sound is to be added and “hi-hat” is used, “hi-hat” which is a typical instrument for engraving the rhythm is used. The musical instrument corresponding to the added performance sound is selected. In addition, when “bass drum” is used in the music data to which the performance sound is added, and “hi-hat” is not used, “bass drum” which is a typical instrument for engraving the rhythm is used. The musical instrument corresponding to the added performance sound is selected. Further, when both “bass drum” and “hi-hat” are used in the music data to which the performance sound is added, “bass drum” and “hi-hat” correspond to the added performance sound. Select as instrument. In addition, when both “bass drum” and “hi-hat” are not used in the music data to which the performance sound is added, the “hi-hat”, which is a typical instrument for engraving the rhythm, is added. Select the instrument that corresponds to the sound.

  The performance sound adding means 60 is preferably predetermined among the plurality of types of musical instruments when the output speed set by the output speed setting means 58 is slower than a predetermined second threshold value. The performance sound according to the addition is added at equal time intervals between adjacent output timings of the performance sounds of the specified instrument, and a second performance sound is further added between the performance sounds according to the addition. to add. The second threshold value corresponds to a tempo slower than the threshold value used for the additional determination of the performance sound, and is, for example, 1/4 of the default value. The performance sound adding means 60 preferably adds the second performance sound at equal time intervals between the performance sounds related to the addition. That is, the performance sound of the musical instrument determined (selected) by the additional musical instrument type determining means 62 is added at equal time intervals between the performance sounds related to the addition. The type of musical instrument corresponding to the second performance sound may be the same musical instrument as the additional performance sound, or may be a different musical instrument. For example, when both “bass drum” and “hi-hat” are used in the music data to which the performance sound is added, “bass drum” and “hi-hat” are musical instruments corresponding to the added performance sound. May be used, a “bass drum” may be used as a musical instrument corresponding to the additional performance sound, and a “hi-hat” may be used as a musical instrument corresponding to the second performance sound.

  The resolution extraction means 64 extracts the resolution of the music (MIDI data) related to performance control by the performance control means 52 (minus one performance control means 54). For example, in the MIDI data in the music data to be performance controlled by the performance control means 52, the time unit (quarter note length) defined in the header is extracted as the resolution of the music related to the performance control. The resolution (time unit) extracted by the resolution extraction means 64 is, for example, “480” or “48”.

  The performance sound adding means 60 is preferably configured to output the performance sound to the second performance sound between the adjacent output timings of the performance sound of the specified musical instrument based on the tempo value and resolution in the MIDI data. Determine the additional position. That is, based on the tempo value corresponding to the output speed set by the output speed setting means 58 and the resolution (time unit) extracted by the resolution extraction means 64, the adjacent output timing of the performance sound of the specified instrument The position of the performance sound (second performance sound) to be added is determined. For example, when the tempo value is not less than the first threshold and not less than the second threshold (threshold corresponding to a tempo slower than the first threshold) and the resolution is “480”, “0 tick”, “120 tick”, “240 tick” , “360 tick” is determined as the additional position. When the tempo value is equal to or greater than the third threshold value (threshold value corresponding to a tempo that is slower than the second threshold value) less than the second threshold value and the resolution is “480”, “0 tick”, “60 tick”, “120 tick” ”,“ 180 tick ”,“ 240 tick ”,“ 300 tick ”,“ 360 tick ”,“ 420 tick ”are determined as the additional positions. When the tempo value is less than the third threshold and the resolution is “480”, “0 tick”, “30 tick”, “60 tick”, “90 tick”, “120 tick”, “150 tick”, “180 tick”, “ "210 tick", "240 tick", "270 tick", "300 tick", "330 tick", "360 tick", "390 tick", "420 tick", "450 tick" are determined as the additional positions. If the tempo value is equal to or less than the first threshold and equal to or greater than the second threshold and the resolution is “48”, “0 tick”, “12 tick”, “24 tick”, and “36 tick” are determined as the additional positions. If the tempo value is less than the second threshold and greater than or equal to the third threshold and the resolution is “48”, “0 tick”, “6 tick”, “12 tick”, “18 tick”, “24 tick”, “30 tick” “36 tick” and “42 tick” are determined as the additional positions. When the tempo value is less than the third threshold and the resolution is “48”, “0 tick”, “3 tick”, “6 tick”, “9 tick”, “12 tick”, “15 tick”, “18 tick”, “ “21 tick”, “24 tick”, “27 tick”, “30 tick”, “33 tick”, “36 tick”, “39 tick”, “42 tick”, “45 tick” are determined as the additional positions.

It is a figure which illustrates additional control, and the performance sound of "hi-hat" is added to output timing "0 tick", "120 tick", "240 tick", and "360 tick". Here, in FIG. 5, the performance sound of “hi-hat” is added to “0 tick” and “480 tick” where the performance sound of “electric guitar” exists, but there is a performance sound corresponding to the prescribed instrument. The performance sound need not be added to the output timing. This is the same in the following description.

  FIG. 6 shows the performance sound in the case where the tempo value of the music data shown in FIG. 4 is less than the second threshold and the third threshold or more, and “hi-hat” is selected as the musical instrument corresponding to the performance sound to be added.

In other words, the performance sound of “bass drum” is output timing “0 tick”, “120 tick”, “240 tick”, “360 tick”, and “snare drum” is output timing “60 tick”, “180 tick”, “300 tick”, “420 tick” ”Has been added. In other words, a performance sound of “snare drum” is further added as a second performance sound between the performance sounds of “bass drum” added as shown in FIG.

  FIG. 9 shows that the tempo value of the music data shown in FIG. 4 is less than the second threshold and greater than or equal to the third threshold, and “bass drum” and “hi-hat” are selected as musical instruments corresponding to the performance sound to be added. It is a figure which shows another example of additional control of the performance sound in the case, and output timings “0 tick”, “60 tick”, “120 tick”, “180 tick”, “240 tick”, “300 tick”, “360 tick”, “420 tick” "Bass drum" and "Hi-hat" performance sounds have been added. That is, the performance sound of “bass drum” is output at “0 tick”, “60 tick”, “120 tick”, “180 tick”, “240 tick”, “300 tick”, “360 tick”, and “hi-hat” at output timing “420 tick” Each performance sound has been added. In such an aspect, while taking the rhythm with the performance sound of the “bass drum” added at regular intervals between the output timings of the performance sound of the “electric guitar” which is the prescribed instrument defined in advance, By outputting the “hi-hat” performance sound immediately before the output timing of the performance sound of the “electric guitar”, it is possible to more appropriately grasp the output timing of the performance sound of the “electric guitar”.

  The performance sound adding means 60 preferably has a predetermined track in the music data corresponding to the same musical instrument as the performance sound to which the performance sound or the second performance sound is to be added. If the output timing of the performance sound (the performance sound being used) coincides with the output timing, the performance sound is not added. Preferably, the time position where the performance sound or the second performance sound should be added corresponds to a predetermined percussion instrument for which the scale of the performance sound cannot be set. If the timing coincides with the output timing, the performance sound is not added. In particular, the “bass drum” is selected as the musical instrument corresponding to the performance sound to be added, and the time position where the performance sound of the “bass drum” should be added is the “snare drum” predetermined in the music data. When the performance sound coincides with the output timing of the performance sound, such performance sound is not added. Further, “snare drum” is selected as the musical instrument corresponding to the performance sound to be added, and the time position where the performance sound of the “snare drum” is to be added is “bass drum” which is predetermined in the music data. When the performance sound coincides with the output timing of the performance sound, such performance sound is not added.

  FIG. 10 is a diagram exemplifying tracks and rhythm tracks corresponding to the prescribed musical instrument in the music data having a resolution of “480” to which the performance sound is added. In the example shown in FIG. 10, one bar (one unit) corresponding to “electric guitar” is illustrated as the prescribed instrument, and the performance sound of the “electric guitar” is displayed in “0 tick” and “480 tick”. Output timing is defined. In the rhythm track, “120 tick” and “360 tick” define the output timing of the performance sound of the “bass drum”.

  FIG. 11 shows the performance sound when the tempo value of the music data shown in FIG. 10 is not less than the first threshold and not less than the second threshold, and “bass drum” is selected as the musical instrument corresponding to the added performance sound. It is a figure which illustrates this additional control. In such a case, the output timings “0 tick”, “120 tick”, “240 tick”, and “360 tick” are determined as additional positions, but “120 tick” and “360 tick” have a performance sound of “bass drum” in advance. Output timing is defined. Accordingly, the performance sound is not added at such output timing, and the performance sound of “bass drum” is added to the output timings “0 tick” and “240 tick”.

  FIG. 12 is a diagram exemplifying tracks and rhythm tracks corresponding to the prescribed musical instrument in music data with a resolution of “480” to which the performance sound is added. In the example shown in FIG. 12, one bar (one unit) corresponding to “electric guitar” is illustrated as the prescribed instrument, and the performance sound of the “electric guitar” is displayed in “0 tick” and “480 tick”. Output timing is defined. Also, in the rhythm track, the output timing of the “snare drum” performance sound is defined for “120 tick” and “360 tick”. When the tempo value of the music data shown in FIG. 12 is not less than the first threshold and not less than the second threshold, and “bass drum” is selected as the musical instrument corresponding to the performance sound to be added, the output timing “0 tick” “120 tick”, “240 tick”, and “360 tick” are determined as the additional positions, and the output timing of the “snare drum” performance sound is determined in advance for “120 tick” and “360 tick”. Accordingly, the performance sound is not added at such output timing, and the performance sound of “bass drum” is added to the output timings “0 tick” and “240 tick”.

  The usage status extracting unit 66 shown in FIG. 3 extracts the usage status of the performance sound corresponding to the musical instrument previously determined in the music data corresponding to the musical instrument added by the performance sound adding unit 60. That is, when a track corresponding to the musical instrument to be added by the performance sound adding means 60 is predetermined in the music data to which the performance sound is to be added, the usage status determined for the track is extracted. Preferably, the volume (Volume) of a performance sound in a track predetermined in the music data corresponding to the musical instrument is extracted. Alternatively, the minimum volume (minimum value of velocity) of the performance sound in the track predetermined in the music data corresponding to the musical instrument is extracted.

  The performance control means 52 preferably controls the usage status of the performance sound of the musical instrument added by the performance sound adding means 60 based on the usage status extracted by the usage status extraction means 66. For example, the volume (Velocity) of the performance sound of the musical instrument added by the performance sound adding means 60 is set to the volume (Volume) or the minimum volume (minimum of the velocity) of the performance sound corresponding to the musical instrument predetermined in the music data. Value).

  FIG. 13 and FIG. 14 are flowcharts for explaining a main part of an example of the performance sound addition control by the CPU 12 of the karaoke apparatus 10, and are repeatedly executed at a predetermined cycle.

  First, in step (hereinafter, step is omitted) SA1, music reservation (music selection input) is accepted in response to an input operation by the operation panel 24 or the like. Next, in SA2, whether or not the guitar navigation mode is established, that is, the performance sound of the track corresponding to the “electric guitar” among the performance sounds of the musical instruments corresponding to the plurality of tracks in the music data is output. It is determined whether or not a minus one performance mode for outputting musical instrument performance sounds corresponding to the remaining tracks is established. If the determination in SA2 is negative, in SA3, normal karaoke performance processing, that is, performance control for outputting performance sounds of all tracks defined in the music data, is performed, and then this routine is terminated. However, if the determination in SA2 is affirmative, in SA4, preparation for performance of a predetermined music is performed according to the performance order of the reserved music table. For example, music data corresponding to the music is read from the music database 48 and developed in the RAM 16 or the like.

  Next, in SA5, the musical instrument used in the music data related to the performance start is checked. That is, the type, resolution, tempo value, and performance sound of each track (for example, performance sound corresponding to “hi-hat” and “bass drum”) for which performance sound (musical score information) is defined for the track in the music data ), The minimum volume value (minimum value of velocity) and the like are extracted. Next, in SA6, the output speed (tempo value) of the music data related to the start of performance is determined according to the operation position of a speed control knob (not shown) provided on the operation panel 24, and the addition of the performance sound is determined. Is determined. Further, based on the resolution extracted in SA5 and the tempo value of the music data determined in accordance with the operation position of the speed control knob, the designated tick that is the additional position of the performance sound is determined. Next, in SA7, the performance output of the music based on the music data developed in the RAM 16 or the like (excluding the track corresponding to “electric guitar”) is started. Thereafter, the sound input from the electric guitar 50 or the like which is an external device is received from the sound effector 46 or the like. Next, in SA8, it is determined whether or not the music performance is completed, for example, the music is played to the end. If the determination at SA8 is affirmed, the routine is terminated accordingly. If the determination at SA8 is negative, the processing from SA9 is executed.

  In SA9, a MIDI command (MIDI event) for 1 tick is executed. That is, the performance sound of the musical instrument specified in the Tick MIDI data is output. Next, in SA10, it is determined whether or not “Closed Hi-Hat” is unused and “Bass Drum” is used in the MIDI data relating to the performance. If the determination of SA10 is negative, the processing from SA16 shown in FIG. 14 is executed. If the determination of SA10 is positive, the tempo value related to the output of MIDI data is SA6 in SA11. It is determined whether or not the threshold value is less than or equal to the threshold value determined in (1). When the determination at SA11 is negative, the processing after SA8 is executed again. However, when the determination at SA11 is affirmative, at SA12, the designated Tick, which is the position where the performance sound is added, is used. It is determined whether or not there is. When the determination at SA12 is negative, the process after SA8 is executed again. When the determination at SA12 is affirmative, the process after SA13 is executed.

  In SA13, it is determined whether or not the number of times the performance sound is added is an odd number (odd number). If the determination in SA13 is affirmative, in SA14, a performance sound of “Bass Drum” is added to the designated Tick and transmitted to the audio processing unit 22 or the like, and then the processing in SA8 or lower is performed. Is executed again, but if the determination in SA13 is negative, that is, if the number of times the performance sound is added is an even number, in SA15, the designated tick is set to “Snare Drum”. After the performance sound is added and transmitted to the sound processing unit 22 and the like, the processing after SA8 is executed again. Here, the volume (Velocity) of the performance sound added in SA14 is smaller than the minimum volume (minimum value of velocity) in each track extracted in SA5. The same applies to SA15, SA21, SA22, and SA25.

  In SA16, it is determined whether or not both “Closed Hi-Hat” and “Bass Drum” are used in the MIDI data relating to the performance. If the determination at SA16 is negative, the processing from SA23 is executed, but if the determination at SA16 is affirmative, the tempo value for the output of MIDI data is determined at SA6 at SA17. It is determined whether or not it is below the threshold value. When the determination at SA17 is negative, the processing after SA8 shown in FIG. 13 is executed again. However, when the determination at SA17 is affirmative, at SA18, the current position is the position where the performance sound is added. It is determined whether or not a specified tick is present. When the determination at SA18 is negative, the process after SA8 shown in FIG. 13 is executed again. When the determination at SA18 is affirmative, the process after SA19 is executed.

  In SA19, a performance sound of “Closed Hi-Hat” is added to the designated Tick and transmitted to the sound processing unit 22 and the like. Next, in SA20, it is determined whether or not the number of times the performance sound is added is an odd number. If the determination of SA20 is affirmative, in SA21, a performance sound of “Bass Drum” is added to the designated Tick and transmitted to the audio processing unit 22 or the like, and then the processing of SA8 or lower is performed. Is executed again, but if the determination in SA20 is negative, that is, if the number of times the performance sound is added is an even number of times, in SA22, “Snare Drum” is added to the designated Tick. After the performance sound is added and transmitted to the sound processing unit 22 and the like, the processing after SA8 is executed again.

  In SA23, it is determined whether or not the tempo value relating to the output of MIDI data is equal to or less than the threshold value determined in SA6. When the determination at SA23 is negative, the processing after SA8 shown in FIG. 13 is executed again. When the determination at SA23 is affirmative, at SA24, the current position is the position where the performance sound is added. It is determined whether or not a specified tick is present. When the determination at SA24 is negative, the processing after SA8 shown in FIG. 13 is executed again. However, when the determination at SA24 is affirmative, at SA25, the designated Tick is set to “Hihat (Closed Hi). -Hat) "is added and transmitted to the sound processing unit 22 and the like, and then the processing from SA8 shown in FIG. 13 is executed again.

  FIG. 15 is a flowchart for explaining a main part of an example of the second performance sound addition control by the CPU 12 of the karaoke apparatus 10, and is executed in parallel with the performance sound addition control described above with reference to FIGS. 13 and 14. Is.

  First, in SB1, it is determined whether or not the tempo value relating to the output of MIDI data is equal to or smaller than a second threshold value smaller than the threshold value determined in SA6. If the determination at SB1 is negative, the routine is terminated accordingly. If the determination at SB1 is affirmative, the second tick is determined between the designated ticks determined at SA6. Designated Tick corresponding to the performance sound addition position is determined at equal time intervals, and in SB2, it is determined whether or not the current Tick is the second performance sound addition position. If the determination at SB2 is negative, the routine is terminated accordingly. If the determination at SB2 is affirmative, "Bass Drum", "Snare Drum ( The performance sound “Snare Drum)” or “Closed Hi-Hat” is added and transmitted to the audio processing unit 22 and the like, and then this routine is terminated.

  FIG. 16 is a flowchart for explaining a main part of an example of performance sound addition control (additional non-execution control) by the CPU 12 of the karaoke apparatus 10, and is performed in parallel with the performance sound addition control described above with reference to FIGS. 13 and 14. Is executed.

  First, at SC1, it is determined whether or not an output timing of a performance sound corresponding to the same musical instrument as the performance sound is determined in advance at the timing of adding the performance sound, that is, the designated Tick. When the determination of SC1 is affirmed, the processing after SC3 is executed, but when the determination of SC1 is negative, the performance sound to be added is “Bass Drum” in SC2. Whether or not the output timing of the performance sound corresponding to “Snare Drum” is determined in advance, or the performance sound to be added is “Snare Drum (Snare Drum)”. ) ”And whether or not the output timing of the performance sound corresponding to“ Bass Drum ”is determined in advance at the timing related to the addition. If the determination at SC2 is negative, the routine is terminated accordingly. If the determination at SC2 is affirmative, at SC3, the performance sound is added at the corresponding timing (designated Tick) and extended. After the transmission to the voice processing unit 22 is not executed, this routine is terminated.

  As described above, in the control described with reference to FIGS. 13 to 16, SA2, SA3, SA7, and SA8 are the operations of the performance control means 52, and SA2, SA7, and SA8 are the operations of the minus one performance control means 54. , SA7 is the operation of the external input receiving means 56, SA6 is the operation of the output speed setting means 58, SA14, SA15, SA19, SA21, SA22, SA25, SB3, and SC3 are the operations of the performance sound adding means 60. SA10, SA13, SA16, and SA20 correspond to the operation of the additional musical instrument type determining means 62, and SA5 corresponds to the operations of the resolution extracting means 64 and the usage status extracting means 66, respectively.

  Thus, according to the present embodiment, the output speed setting means 58 (SA6) for setting the output speed of the music data, and the output speed set by the output speed setting means 58 is lower than a predetermined threshold value. In the case of being late, a performance in which performance sounds of instruments different from the instrument are added at equal time intervals between adjacent output timings of performance sounds of a predetermined instrument among the plurality of types of instruments. Since the sound adding means 60 (SA14, SA15, SA19, SA21, SA22, SA25, SB3, and SC3) is provided, the performance sound for taking a rhythm between the performance sounds of the prescribed instruments Are added at equal intervals, for example, even when the output speed is set to be extremely slow, the user can easily take a rhythm. That is, it is possible to provide the karaoke apparatus 10 as a music performance apparatus that allows the user to take a rhythm appropriately regardless of the setting of the performance speed.

  Further, since the musical instrument corresponding to the performance sound added by the performance sound adding means 60 is selected from musical instruments having tracks corresponding to the music data, the musical instrument used in the target music data By using the performance sound as a performance sound for taking a rhythm, it is possible to suitably suppress the user from feeling uncomfortable by adding the performance sound.

  Further, the volume of the performance sound of the musical instrument added by the performance sound adding means 60 is set so as to be lower than the volume of the performance sound corresponding to the musical instrument predetermined in the music data. Thus, it is possible to easily distinguish between a performance sound added for taking a rhythm and a performance sound predetermined for music data.

  The music data is MIDI data, and the performance sound adding means 60 performs the performance between adjacent output timings of the performance sound of the specified musical instrument based on the tempo value and resolution in the MIDI data. Since the position where the sound is added is determined, in a music performance device that performs performance output based on MIDI data, which is widely used music data, a performance sound for taking a rhythm between the performance sounds of the prescribed instruments is used. It can be added in a suitable and practical manner.

  Further, since the musical instrument corresponding to the performance sound added by the performance sound adding means 60 is a percussion instrument that cannot set the scale of the performance sound, for example, a bass drum, a snare drum, a hi-hat, etc. are used exclusively for taking a rhythm. By adding the performance sounds of the specified instrument between the performance sounds of the prescribed instruments, it is possible to allow the user to take a rhythm in a suitable and practical manner without giving the user a sense of incongruity. it can.

  Further, the performance sound adding means 60 has a time position where the performance sound should be added coincides with an output timing of the performance sound predetermined in the music data corresponding to the same musical instrument as the performance sound to be added. In this case, since the performance sound is not added, it is possible to allow the user to take a rhythm by using the existing performance sound together without performing unnecessary control.

  The performance sound adding means 60 outputs the performance sound output timing predetermined in the music data corresponding to a specified percussion instrument whose time position to which the performance sound should be added cannot set the scale of the performance sound. Since the performance sound is not added in the case of a match, for example, the performance sound of the bass drum and the performance sound of the snare drum are duplicated and output, which is impossible in terms of music. It is possible to allow the user to take a rhythm by using the existing performance sound together while suppressing the above.

  Further, the performance sound adding means 60, when the output speed set by the output speed setting means 58 is slower than a predetermined second threshold, a predetermined rule among the plurality of types of musical instruments. The performance sound according to the addition is added at equal time intervals between the adjacent output timings of the performance sounds of the musical instrument, and a second performance sound is further added between the performance sounds according to the addition. Therefore, the user can easily take a rhythm even when the output speed is set to be slower by appropriately adding a performance sound for taking a rhythm as necessary.

  Further, the performance sound adding means 60 has a performance sound predetermined in the music data corresponding to a specified percussion instrument in which the time position where the second performance sound should be added cannot set the scale of the performance sound. Since the second performance sound is not added when it coincides with the output timing, the bass drum performance sound and the snare drum performance sound are output redundantly, for example. Thus, it is possible to allow the user to take a rhythm by using the existing performance sound together while suppressing the performance output that is impossible.

  The performance sound adding means 60 adds the second performance sound at equal time intervals between the performance sounds related to the addition, so that a performance for taking a rhythm as necessary is obtained. By appropriately adding a sound to a suitable time position, the user can easily take a rhythm even when the output speed is set slower.

  The musical instrument corresponding to the performance sound added by the performance sound adding means 60 can be arbitrarily selected by the user from the plurality of types of musical instruments, and therefore corresponds to the performance sound for taking the rhythm. By enabling the user to select the type of musical instrument, it is possible to more suitably suppress the user's uncomfortable feeling due to the addition of the performance sound.

  Also, the external input receiving means 56 (SA7) that receives input of audio information from the electric guitar 50 as an external device connected to the karaoke apparatus 10, and the audio information from the electric guitar 50 by the external input receiving means 56. Of the musical instruments corresponding to the plurality of tracks in the music data, the performance of the musical instrument corresponding to the remaining tracks without outputting the musical performance of the track corresponding to the prescribed musical instrument. Since the minus one performance control means 54 (SA2, SA7, and SA8) for outputting a sound is provided, an instrument such as an electric guitar 50 is connected to the karaoke apparatus 10, and the performance output by the karaoke apparatus 10 is output. In the form where the user performs the performance practice of the musical instrument in accordance with the Even if it is late set to end it can take the user to easily rhythm.

  The preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to these embodiments, and may be implemented in other modes.

  For example, in the above-described embodiment, the performance of the plurality of types of musical instruments is based on music data in which a plurality of tracks corresponding to the plurality of types of musical instruments are provided and the output timing of the performance sound of the corresponding musical instrument is determined in each track. The present invention is a karaoke apparatus 10 that performs performance output of music data selected from a large number of music data, and displays a lyric character video of the music on a video display device, as a music performance device that outputs sounds in parallel. However, the present invention is not limited to this example, and can be applied to other types of music performance apparatuses. For example, the present invention is also suitable for a music performance device as a musical instrument performance training device used exclusively for practicing the performance of an instrument such as the electric guitar 50, a consumer game machine for executing a game such as a so-called sound game, and the like. Applies to

  Further, in the above-described embodiment, the minus one performance control means 54, when the external input acceptance means 56 accepts input of audio information from an instrument such as the electric guitar 50, the track corresponding to that instrument. The performance sound of the musical instrument corresponding to the remaining track is output without outputting the performance sound, but this is just an example of suitable control, and the external input receiving means 56 is used to play the musical instrument such as the electric guitar 50. Even in the case where the input of audio information is not accepted, performance control by the minus one performance control means 54 can be performed. In such an aspect, for example, even when an acoustic guitar that cannot be connected to the karaoke apparatus 10 is practiced, there is an advantage that the user can easily take a rhythm while realizing effective practice. .

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
