The MIDI section track section (tracks 1 to 15 MIDI data) includes a data block (1), a data block (2),..., A data block (n), and a data block end. The data block portion (data blocks (1) to (n)) is composed of a delta value and a transfer MIDI data string.

  The performance control means 80 develops the target MIDI data in a storage device such as the RAM 42 when outputting a musical composition based on the MIDI data. FIG. 7 is a diagram illustrating a MIDI ring buffer formed in the RAM 42. As shown in FIG. 7, the MIDI ring buffer is composed of MIDI buffers (1) to (64) for 64 records, and each MIDI buffer has 4-bar counter transmission timing, 4-bar step transmission timing, transfer size, In addition, a transfer MIDI byte sequence is stored. FIG. 8 is a diagram illustrating a control ring buffer formed in the RAM 42 corresponding to the MIDI ring buffer. As shown in FIG. 8, the control ring buffer is composed of control buffers (1) to (64) for 64 records, and each control buffer has 4-bar counter execution timing, 4-bar step execution timing, and control information. Is to be memorized. FIG. 9 is a diagram for explaining the 4-bar counter and 4-bar steps. The 4-bar counter is a counter to which 1 is added every time the performance progresses for 4 bars, and monotonically increases without decreasing in the arrangement performance mode described later. The four-bar step is a value indicating time information in the four bars, and is reset to zero every four bars. Further, these four bar steps are the finest (minimum resolution) time information in the performance based on the MIDI data, and when the time base is 48, 192 for one bar and 768 for four bars.

  FIG. 10 is a diagram illustrating a development table formed in the RAM 42. This expansion table is an area for temporarily storing information necessary for template expansion. The expansion information for 64 records, that is, the expansion information at the time of a four-measure counter where the remainder value at 64 is 0, Expansion information at the time of a four-measure counter with a remainder value of 1,..., Development information at the time of a four-measure counter with a remainder value at 62 of 62, and information at the time of a four-measure counter with a remainder value of 63 at 64 The expansion information is expanded. The expansion information of each MIDI buffer includes 1 bar development information, 2 bars development information, 3 bars development information, 4 bars development information, 8th note 1st code information, 8th note 2nd code Information, third eighth chord information,..., Eighth thirty first chord information, and eighth eighth thirty second chord information. When the performance control means 80 outputs the performance tune, the MIDI data developed on the RAM 42 in this manner is read as needed and sent to the MIDI sound source 56, and the control information in the control ring buffer is read out. The performance output from the MIDI sound source 56 is performed.

  Returning to FIG. 3, when the performance control means 80 sequentially outputs a plurality of performance songs by the performance control means 80, the key performance control means 84 performs a predetermined key performance having a predetermined tempo in parallel (synchronized) with the output of the performance music. Is output. The keynote performance preferably has a constant tempo (not necessarily constant), and has a sense of unity so that the genre can be known by itself when listening to rhythms, chords, and tunes. It consists of a syllable or melody, and a plurality of types (genres) of key performances such as house, trance, hip hop, reggae and the like are predetermined. The tempo is a reference speed for playing music, and determines the time length of each note in the case of a musical score. Preferably, a predetermined key performance can be selected by an input operation of the electronic quick sample device 22 or the like from a plurality of types of key performances determined in advance. The predetermined key performance selected by the input operation is output in parallel with the output of the performance music. The arrangement performance mode for sequentially outputting a plurality of performance songs on the key performance, that is, the control operation by the key performance control means 84 will be described in detail below.

  The keynote performance control means 84 includes a raw sound output control means 86 and a MIDI replacement control means 88. Specifically, the keynote performance is output by the raw sound output control means 86 and the MIDI replacement control means 88. The raw sound output control means 86 causes the codec unit 34 to decode the sound data as predetermined raw sound data (information that can be directly converted into analog sound information by decoding) to output the key performance. The key performance database 68 provided in the hard disk 44 stores a plurality of audio data having at least a constant tempo corresponding to each genre and having a sense of unity in rhythm, chords, tunes, and the like. The raw sound output control means 86 continuously decodes the plurality of audio data via the codec unit 34 and outputs the decoded data as the key performance. As the audio data, various file formats such as PCM format data, WAV data and MPEG format data can be considered. The audio data preferably has a length of 4 bars (or 1 bar) at the tempo for each genre, and the data of 4 bars (or 1 bar) is output at the time of output. Is continuously decoded, so that the keynote performance is output so that the user's ear can hear it as a series of music. The keynote performance based on the audio data corresponds to a drum track in the MIDI data. This is because the drum track in MIDI data generally takes into account the peculiarity that each keyboard is associated with a musical instrument rather than a pitch, and the keynote performance based on the audio data is preferably Output as an alternative to drum tracks in MIDI data.

  Preferably, when the performance control means 80 sequentially outputs a plurality of performance tunes, the live sound output control means 86 does not output the performance tunes, that is, between performance tunes (waiting for the next tune performance). The keynote performance based on the audio data is also continuously output. That is, in the arrangement performance mode of the present embodiment, between the performance songs until the output of one performance music is finished and the output of the next performance music is started, the performance music is output along with the performance of those performance music. A key performance for a song having the same tempo, rhythm, music tone, etc. as the key performance is output, and the performance music and the performance music are connected by a uniform syllable or melody. . As a result, it is possible to prevent a problem that the arrangement is interrupted every time the performance of one piece of music is finished, and it is possible to favorably maintain the atmosphere of the exciting place.

  Here, the MIDI data stored in the music database 66 preferably includes a plurality of sections related to performance time information, and the raw sound output control means 86 determines the plurality of sections according to these sections. Are sequentially output in parallel with the output of the performance music by the performance control means 80. This division is, for example, a performance division defined in the meta information of the MIDI data. That is, the meta information of the MIDI data includes, for example, an intro, Amelo, Bmelo, Cmelo, fill, chorus, and interlude at predetermined performance times. , And variable beats, etc. are defined, and the raw sound output control means 86 outputs audio data corresponding to these divisions in units of one measure. In the key performance database 68, for each genre, there are a plurality of types (for example, five types) such as “non-exciting”, “exciting”, “Fill”, “connection to next”, and “connection to song waiting”. ) Are stored for a plurality of sets (for example, 4 sets), and each set stores at least one piece of audio data for each of the classifications. The live sound output control means 86 outputs, for example, audio data corresponding to “swell” in parallel with the performance when the performance of the category in which the meta information in the MIDI data is intro or rust, and the meta information is A When playing a melody, B melody, C melody, or an interlude performance, audio data corresponding to “non-climax” is output in parallel with the performance, Simultaneously with the performance, the audio data corresponding to “Fill” is output, and while the performance music is not being output, that is, when waiting for the next music performance, “connection to next” or “connection to music waiting” Audio data corresponding to is output. As described above, a plurality of audio data having a sense of unity in rhythm, tempo, music tone, and the like are continuously output in synchronization with the output of the performance music based on the MIDI data. It is possible to realize a performance form in which a plurality of performance songs are output on the performance.

  The MIDI replacement control means 88 replaces at least one of the plurality of tracks in the MIDI data with predetermined key performance data. For example, among 16 tracks in the MIDI data developed in the development table, a bass track and / or a synthesizer system track is recorded with predetermined key performance data prior to the output of a performance song based on the MIDI data. Replace with. Here, the key performance data to be replaced is data for outputting a syllable or melody having a unified sense of rhythm, tempo, melody, etc. corresponding to each genre. Like the other tracks, the MIDI sound source 56 performs a performance based on the key performance data. That is, a performance song based on the MIDI data is output in a state in which a predetermined track of the plurality of tracks in the MIDI data is replaced with the key performance data, so that a track corresponding to the key performance data is output. Is output as the key performance. At this time, since the key performance corresponding to the replaced key performance data has a sense of unity in the rhythm, tempo, and tune, etc., a plurality of performance songs are output in a predetermined rhythm with the sense of unity. Can be realized.

  The MIDI replacement control means 88 preferably creates the key performance data by transposing the key performance data template stored in the key performance database 68 according to the target MIDI data. Here, transposition is a shift to another key while maintaining a relative pitch relationship of a predetermined chord or melody, that is, transposition. In the key performance database 68, for each genre, there are a plurality of types (for example, five types) such as “non-exciting”, “exciting”, “Fill”, “connection to next”, “connection to waiting for music”. A plurality of (for example, four) sets of classified key performance data templates are stored. That is, in this embodiment, a key performance data template is determined in advance corresponding to a plurality of types of audio data output by the raw sound output control means 86. Each set in each genre includes 13 types of codes (1 type for “connection to next” and “connection to waiting for song”), that is, “C”, “Cm”, “ 13 keynotes corresponding to “Caug”, “C6”, “CM7”, “C7”, “Csus4”, “Cm6”, “Cm7”, “Cdim”, “Cm7b5”, “Cb5”, “Cmb5” A data template is stored. That is, all the keynote performance data templates are prepared in the C key, and are used by being shifted up and down from the C key in accordance with the chord of the target section.

  The MIDI replacement control means 88 transposes a template whose code matches that of the 13 types of templates corresponding to “rising”, for example, with respect to a category whose meta information in the MIDI data is intro or rust. The key performance data is created, and a predetermined track in the section is replaced with the key performance data. In addition, for a category whose meta information is A melody, B melody, C melody, or interlude, the keynote performance is transposed from the 13 types of templates corresponding to “non-excited” and the template matches the chord. Data is created, and a predetermined track in the section is replaced with the key performance data. In addition, for a category whose meta information is “fill”, key performance data is created by transposing a template whose chord matches that of the 13 types of templates corresponding to “Fill”, and a predetermined track in the category is created. Is replaced with the key performance data. When two or more tracks are replaced with key performance data such as a bass track and a synthesizer track, the template is transposed and replaced for each track.

  In the keynote performance database 68, only one type of template corresponding to “connection to next” and “connection to tune waiting” is stored one by one. This is because it is assumed that the performance music based on the MIDI data is not output, that is, between performance music (waiting for the next music performance), and it is not necessary to transpose. That is, the MIDI replacement control means 88 obtains the key performance data from the key performance data template stored in the key performance database 68 between the performance songs for which performance music based on the MIDI data is not output. The key performance data is created and sent to the MIDI sound source 56 to output a key performance based on the key performance data. Specifically, first, after outputting one to several measures of the key performance based on the key performance data corresponding to the “connection to the song waiting” template, “connection to the next” is started until the output of the next song is started. The key performance based on the key performance data corresponding to the template is repeatedly output. As described above, the MIDI replacement control means 88 is based on the keynote performance data template while the performance control means 80 is not outputting the performance music, that is, between performance music (waiting for the next music performance). Since the performance is continuously output, it is possible to prevent a problem that the arrangement is interrupted every time the performance of one piece of music is finished, and it is possible to favorably maintain the atmosphere of the excitement.

  11 to 14 are diagrams for explaining replacement of MIDI data by the MIDI replacement control means 88. FIG. Preferably, the key performance data template is prepared in units of one bar as in the case of the audio data. The key performance data template is transposed and connected to the key performance data. Is done. For example, as shown in FIGS. 11 and 12, two types of key performance data templates (hereinafter, those shown in FIG. 11 are referred to as template data A, and those shown in FIG. 12 are referred to as template data B) are used for MIDI data. Considering the case of replacement, first, as shown in FIG. 13A, the RAM 42 is secured with a connected reading area for four bars and a temporary reading area for one bar. Next, as shown in FIG. 13B, the template data A shown in FIG. 11 is stored in the temporary reading area. Next, as shown in FIG. 13C, the template data A stored in the temporary reading area is stored (copied) in the linked reading area. Next, as shown in FIG. 13D, the template data B shown in FIG. 12 is stored in the temporary reading area. Next, as shown in FIG. 13E, the template data B stored in the temporary reading area is linked (stored) to the template data A in the linked reading area. By repeating the storing and connection as described above for four bars, key performance data for four bars is formed in the connection reading area, and the key performance data thus formed is shown in FIG. As described above, the data is stored in a predetermined track in the performance area secured in the RAM 42 (replaced with the data stored in the track). Note that when MIDI data is held separately for each track, each track has a variable length, so the actual data size of each track even when played on the time axis with the same length. May be different.

  Here, when the key performance data is created by transposing the key performance data template, the MIDI replacement control means 88 preferably performs correction for reducing the uncomfortable performance on a predetermined track. Do. For example, when creating the key performance data corresponding to the bass track, if the lowest tone is equal to or lower than a predetermined sound (for example, C1) by transposing the key performance data template in accordance with the target category, The key performance data is created by transposing one more octave after the pause. In addition, when the highest tone exceeds a predetermined tone (for example, F3) by transposing the key performance data template in accordance with the target section, it is further transposed one octave lower after the transposition. The key performance data is created. In this way, for example, the key performance data corresponding to the bass track can be within the predetermined range (C1 to F3), and the key performance corresponding to the bass is too low or too high. Can reduce the sense of incongruity in performance.

  FIG. 15 is a diagram illustrating a template file name table 70 used for outputting the key performance. The template file name table 70 may be stored in advance in a storage device such as the hard disk 44, or is created each time a genre is selected at the start of the arrange performance mode and is stored in the RAM 42 or the like. It may be temporarily stored. As shown in FIG. 15, the template file name table 70 includes voice data for outputting a key performance via the codec unit 52 and a key performance data template used for replacing a predetermined track in the MIDI data. Are defined in association with each other. That is, four sets of data from a set 0 to 3 are defined for a predetermined genre, and each set includes the above-described five classifications, that is, “non-exciting”, “exciting”, “Fill”, “next connection” , One voice data (raw sound) and thirteen key performance data templates (MIDI-1 to MIDI-13) are defined corresponding to each of the “connection to music waiting”. Here, the audio data and the key performance data template defined in the same classification in each set are used corresponding to the common category in the target MIDI data, in other words, the key performance control. The means 84 sequentially decodes a plurality of audio data stored in the key performance database 68 via the raw sound output control means 86 by the codec unit 34 according to the division, and synchronizes with the output of the audio data. Then, the MIDI data track replacement is performed via the MIDI replacement control means 88 so that the key performance based on the key performance data template corresponding to each audio data is output. As described above, in this embodiment, the key performance by decoding the audio data through the raw sound output control means 86 and the predetermined track of the MIDI data by the MIDI replacement control means 88 are replaced with the key performance data in advance. In the above description, a mode is described in which a key performance by playing through the MIDI sound source 56 is output in parallel (simultaneously), but a mode in which only one of the two types of key performance is output is also possible. Conceivable.

  Preferably, the MIDI data has a head flag for taking a beat timing one measure before (192 steps before) an intro flag indicating a start position of a section whose meta information is intro. The replacement control means 88 controls replacement of a predetermined track in the MIDI data according to the head flag. That is, control is performed so that replacement of a predetermined track in the MIDI data starts from one measure after the head flag. Generally, MIDI data has a predetermined time from the start of data setup to the start of output. As described above, the MIDI replacement control means 88 performs the keynote performance from the keynote performance data template stored in the keynote performance database 68 between performance songs for which performance music based on the MIDI data is not output. Data is generated, and the key performance data is sent to the MIDI sound source 56 to output the key performance based on the key performance data. The key performance based on the key performance data corresponding to the “connection” template is repeatedly output. Here, when the start of the MIDI data of the next song is one bar (step 192), that is, when the setup is performed one bar before the intro flag indicating the start position of the segment whose meta information is intro. At the same time as the start of the setup, the output of the keynote performance based on the keynote performance data corresponding to the “connection to next” template is stopped, and there is a rest section of one measure, and then the meta information is intro Control is performed so that the above-described replacement of the predetermined track is performed from the start position of the section. On the other hand, when the start of the MIDI data of the next song after the setup is not one bar (192 steps), the timing will not match if the replacement of the predetermined track is started one bar after the start of the setup. Therefore, in such a case, simultaneously with the start of setup, the output of the key performance based on the key performance data corresponding to the “connection to next” template is stopped, and the above-described predetermined track replacement is performed after step 192 of the head flag. Is controlled to be performed. Further, the performance control means 80 is arranged so that the tempo of the performance music output based on the MIDI data matches the tempo of the key performance based on the audio data output from the raw sound output control means 86. The output start timing of the target MIDI data is controlled based on the above.

  Returning to FIG. 3, the performance control means 80 corrects the tempo of the output performance song according to the tempo of the key performance output by the key performance control means 84 in parallel with the output of the performance music. Correction means 82 is included. In general, since the tempo of audio data (raw sound data) is fixed, a plurality of performance songs based on MIDI data are sequentially output in parallel with the basic performance by decoding the audio data via the raw sound output control means 86. In this case, it is necessary to adapt the performance tempo of the MIDI data to the tempo of the audio data. For this reason, the tempo correction means 82 preferably uses the tempo of the performance song output via the MIDI sound source 56 and the keynote output via the codec unit 52 in parallel with the output of the performance song. Practically, it becomes 1/2 times, 1 time, or 2 times so that it becomes 1 / n times, 1 time, or n times (n is a power of 2) the tempo of performance, that is, the tempo of audio data. Correct as follows. FIG. 16 is a diagram exemplifying a tempo correction table 72 used for the output tempo correction of the performance tune by the tempo correction means 82. As shown in FIG. 16, the genre selected at the start of the arrangement performance mode, such as tempo = 70 in the reggae air range, tempo = 90 in the hip hop arrangement, tempo = 125 in the house arrangement, and tempo = 140 in the trans arrangement. A predetermined tempo is predetermined for each, and this tempo matches the tempo of the audio data in each genre. The tempo correction means 82 forcibly corrects the tempo value held by the music corresponding to each genre, that is, the output tempo of the MIDI data. Note that the basic performance that is output by replacing a predetermined track of the target MIDI data via the MIDI replacement control means 88 depends on the tempo of the target MIDI data, so the performance tempo of the MIDI data is determined. By adapting to the tempo of the audio data, the output tempo of the key performance by replacing the predetermined track naturally matches the tempo of the audio data.

  In FIG. 16, “4” indicates the MIDI data performance tempo is ½ times the tempo of the audio data, “2” is 1 time the tempo of the audio data, and “1” is twice the tempo of the audio data. It shows that each is corrected. In other words, in the reggae air range with tempo = 70, music with a default tempo value of 50 or less is tempo = 35, which is half the tempo of the audio data, and music with a default tempo value of 51 or more and 104 or less. Tempo = 70, which is one time the tempo of the audio data, and music whose default tempo value is 105 or more are corrected to tempo = 140, which is twice the tempo of the audio data. In a hip-hop arrangement with tempo = 90, a song with a default tempo value of 50 or less has a tempo = 45, which is half the tempo of the audio data, and a song with a default tempo value of 51 to 139. Is corrected to tempo = 90, which is one time the tempo of audio data, and music whose default tempo value is 140 or more is corrected to tempo = 180, which is twice the tempo of audio data. Further, in the house arrangement with tempo = 125, the music whose default tempo value is 93 or less has a tempo = 62.5 which is ½ times the tempo of the audio data and the default tempo value is 94 or more and 187 or less. The music is corrected to tempo = 125, which is one time the tempo of the audio data, and the music whose default tempo value is 188 or more is corrected to the tempo = 250, which is twice the tempo of the audio data. Also, in the trans-arrangement with tempo = 140, music with a default tempo value of 97 or less is tempo = 70, which is half the tempo of audio data, and music with a default tempo value of 98 or more and 209 or less. Tempo = 140, which is one time the tempo of the audio data, and music whose default tempo value is 210 or more are corrected to tempo = 280, which is twice the tempo of the audio data. As described above, when a plurality of performance tunes are sequentially output by the performance control means 80, the performance tempo of the performance tunes is made the key performance tempo by decoding the audio data via the raw sound output control means 86. By adapting, the performance music based on the MIDI data and the tempo of the key performance based on the audio data are synchronized (synchronized). As a result, it is possible to realize a performance form in which a plurality of performance songs are organically combined with a predetermined rhythm with a sense of unity, giving the user the impression of a series of continuous songs.

  Here, considering that the performance tempo of the musical composition is made to be ½ times or twice the tempo of the audio data to be output in parallel by the tempo correction means 82, the key performance based on the key performance data template. There may be a case where correction is necessary for replacement of data. For example, the voice data and the key performance data template stored in the key performance database 68 with the classification of “Fill” are used for the classification in which the meta information in the MIDI data is “fill” as described above. Is, for example, a section of one measure immediately before the start of the section whose meta information is chorus. Regarding the application of the key performance data based on the key performance data template in this category, when the performance tempo of the MIDI data is doubled by the tempo of the audio data to be output in parallel by the tempo correction means 82, Since the section in which the meta information in the MIDI data is “fill” is half as long as the default, the key performance data obtained by transposing the key performance data template is directly applied to the chorus section. It will take up to. Further, when the performance tempo of the MIDI data is set to ½ times the tempo of the audio data to be output in parallel by the tempo correction means 82, the division in which the meta information in the MIDI data is “fill” is the default. Since the key performance data obtained by transposing the key performance data template is applied as it is, the length is twice as long as that of the case, so that it starts from two bars before the division where the meta information is rusted. For this reason, the MIDI replacement control means 88, when the tempo correction means 82 makes the performance tempo of the performance music ½ or twice the tempo of the audio data to be output in parallel, “Fill”. The track replacement is performed so that the key performance data based on the key performance data template stored in the above category is applied to the section of one measure immediately before the section whose meta information is chorus.

  Further, when the performance tempo of the musical composition is doubled by the tempo of the audio data to be output in parallel by the tempo correction means 82, it is necessary to correct the resolution referring to the development information and chord information of MIDI data. There is. For example, in the default MIDI data, the resolution of a quarter note is set to 48 steps, which is equivalent to the resolution of an eighth note being 24 steps. The performance control means 80 outputs performance music based on the MIDI data with reference to the development information and chord information of the MIDI data with such resolution, and the tempo correction means 82 performs the performance of the performance music. When the tempo is set to twice the tempo of the audio data to be output in parallel, the resolution of the eighth note is set to 48 steps. Therefore, the default MIDI data for reference to development information, chord information, etc. Differences occur between For this reason, when the performance control means 80 uses the tempo correction means 82 to double the performance tempo of the musical composition to be output in parallel, the resolution of the eighth note is equivalent to 24 steps. Make corrections so that Alternatively, a mode is also conceivable in which even-numbered data is ignored by referring to only odd-numbered data among the development information and chord information for each eighth note.
