Description

  The present invention relates to a performance information editing / playback apparatus for editing performance information for performing an automatic performance or automatic accompaniment in an electronic musical instrument or the like.

  2. Description of the Related Art Conventionally, in the technical field of electronic musical instruments and computer music, there are some that perform automatic accompaniment by playing performance information called style data composed of pitch data and timing data, for example. Such style data is composed of a plurality of parts such as percussion instruments and other accompaniment parts. In addition, the user performance data including a plurality of parts can be created or edited, and the user performance data can be reproduced.

  In the function of editing and reproducing such performance information, the following processing is conventionally performed.

  In order to create user performance data using style data composed of multiple parts, there is a function to copy the style data as user performance data. The user performance data is recorded in the recording area.

  Further, at the time of reproduction, user performance data and style data can be reproduced simultaneously.

  There is also a recording mode in which performance data can be recorded (recorded) on a part designated by user performance data by operating a recording switch and a start switch.

  It should be noted that there is no prior art document information to be disclosed because there is no document known invention related to the present invention that the applicant knows at the time of filing the patent.

  When writing (copying) style data to user performance data, all the parts of the style are written at once, so it is possible to create extensive performance data by copying only a part of the style. If possible, it is easy to edit and easy to use. Even in such a case, conventionally, since the user performance data and the style data are reproduced at the same time, the performance as intended by the user may not be reproduced. In particular, when style data and user performance data have parts that are duplicated in the same sound source channel, the music source will play a music that is a merged part of the overlapping sound source channels, which is inconvenient. is there.

  Furthermore, in the recording mode in which recording is possible with the recording switch and the start switch, when the user designates a part (when recording is performed) and when the user does not designate a part (when recording is not performed) The display state is exactly the same, and it is difficult to intuitively understand whether or not performance data is recorded.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a performance information editing / playback apparatus that is easy to use when creating, editing, and the like of user performance data.

Playing information playback apparatus according to claim 1, the style data memory means the musical event storing the recorded style data with the timing to form the accompaniment tone at the reference chord, and sequentially recorded melody part tone event with timing, Accompaniment parts that record musical sound events sequentially with timing, style sequences that record style instruction events that specify style data sequentially with timing, and chord events that are information for instructing chords as the performance progresses with timing comprising a user performance data storage means for storing user performance data is composed of a sequential record code sequence, and the performance information playback apparatus capable of playback of the user performance data, the accompaniment part is the code sequence Chord event Together comprising a tone event recorded the style data and voice pitch converting a based, corresponding to the instrument channel or tone of style data indicated by the sound source channel or the style sequence and tone of the accompaniment parts are the same and which, in accordance with the selection operation Yu chromatography the, whereas one of the musical event style data sequentially indicated by the style sequence according to the playing progression tone event of the accompaniment part of the user's performance during data selection means for selecting, the time to the user of the performance data reproducing means for reading a musical event of one and the melody part tone event or the style data tone event of the accompaniment parts selected by said selection means If, musical event of the read-out the accompaniment part The other is to play both the musical event of the style data and musical event of the melody part, said when you play a musical event of the style data, in accordance with the play progresses, the musical tone from the style data that has been instructed by the style sequence When an event is read out and the musical tone event thus read is converted based on the chord event of the chord sequence, and the musical tone event of the accompaniment part is played back, the style data is converted into a pitch and recorded. Means for reproducing a musical sound event of the accompaniment part including a musical sound event .

According to the performance information editing / playback apparatus of the first aspect, either one of the predetermined part of the user performance data and the part of the style data can be alternatively selected and reproduced together with a part other than the predetermined part of the user performance data. Therefore, the performance as intended by the user can be reproduced and the usability is improved. Further, the predetermined part of the user performance data and the plurality of parts of the style data have the same sound source channel or timbre, and these parts are alternatively selected and reproduced, so these parts are merged. Music is never played.

Further, the selected style data can be reproduced with a pitch suitable for a part other than the predetermined part of the user performance data.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 9 is a block diagram of an embodiment in which the performance information editing / playback apparatus of the present invention is configured by a personal computer and software. The personal computer main body includes a CPU 1, ROM 2, RAM 3, timer 4, external storage device 5, detection circuit 6, display circuit 7, communication interface 8, and MIDI interface 9.

  The detection circuit 6 is an input interface and inputs an operation event of the mouse and the keyboard 11. The display circuit 7 is a video card, a video chip or the like, and performs display control of the display 12. The communication interface 8 is connected to a communication network 13 such as a LAN (local area network), the Internet, or a telephone line to communicate with a server computer or the like. Further, the MIDI interface 9 performs MIDI communication with a sound source device (MIDI device) 14, and outputs MIDI data to the sound source device 14 when reproducing user performance data and style data. The sound source device 14 generates musical sounds from the sound system 15. . The timer 4 is a circuit for generating various interrupt signals for performing each interrupt signal for performing reproduction / recording interrupt processing or for interrupt processing for detecting an operation event of the keyboard.

  The CPU 1 performs normal control using the working area of the RAM 3 by an OS (operating system) installed in a hard disk device (HDD) of the external storage device 5, for example. Specifically, for example, display of the display 12 is controlled, data corresponding to the operation of the mouse and keyboard 11 is input, control of the display position of the mouse pointer (cursor) on the display 12 and detection of a mouse click operation. Etc. Thereby, an input setting operation or the like by the user is executed by a so-called graphical user interface (GUI) process by displaying on the display 12 and operating the mouse.

  The external storage device 5 is a floppy disk device (FDD), a hard disk device (HDD), a magneto-optical disk (MO) device, a CD-ROM device, a digital multipurpose disk (DVD) device, and the like. A performance information editing / playback program is provided. The external storage device 5 is used to store the created user performance data, or is used as a database of music template data and style data that is basic information when creating user performance data.

  It is also possible to connect to the communication network 13 via the communication interface 8 and receive various data such as a performance information editing / playback program, song template data, or style data from the server computer. In this embodiment, the performance information editing / playback program, song template data, and style data are stored in the hard disk device (HDD) of the external storage device 5, and the CPU 1 edits / plays back the performance information of the hard disk device (HDD). The program is developed in the RAM 3, and the performance information editing / playback process is controlled based on the program in the RAM 3.

  FIG. 3 is a diagram showing an example of a format of user performance data in the embodiment. The user performance data is data for music reproduction created by the user. One user performance data includes a melody part part 1, an accompaniment part part 2, a percussion instrument part part 3, a style sequence which is time series data of accompaniment styles, and a chord sequence indicating chord progression. It is configured.

  In each of the parts 1, 2, and 3, timing and musical sound event information are sequentially recorded after the initial information such as timbre and tempo, and finally end data is recorded. The style sequence is information for sequentially reading out styles in accordance with the progress of performance. Instruction events for instructing timing and style are sequentially recorded, and finally end data is recorded. Furthermore, the chord sequence is information for instructing chords in accordance with the progress of the performance. Chord events, which are information indicating the chord type, root tone, bass tone, etc., are recorded sequentially with timing, and finally the end data is recorded. To be recorded. In the following description, each of the parts 1, 2, and 3, the style sequence and the code sequence is also referred to as “track”.

  FIG. 4 is a diagram illustrating an example of a format of style data in the embodiment. This style data is accompaniment playback data prepared in advance, and is stored in the ROM 2 or the external storage device 5 for each of many music genres such as jazz and rock (that is, the prepared data itself) Cannot be changed). The style data is composed of two parts, an accompaniment part 2 and a percussion instrument part 3. Each part 2 and 3 has initial information such as timbre followed by timing and musical event information. Recorded, and finally end data is recorded. Part 2 other than the percussion instrument part is data corresponding to the musical score of the music based on a predetermined reference chord (for example, C measure). When this style data is read during reproduction, a musical tone event is based on the chord of the chord sequence. The pitch information inside is converted into a pitch that matches the chord.

  Here, in the user performance data, an accompaniment part and a percussion instrument part are assigned to parts 2 and 3, and the style data is read out by a style sequence, and the accompaniment part and the percussion instrument part can also be reproduced by this style data. However, this enables the accompaniment sound (accompaniment + percussion instrument) to be added to the melody even with the data of only the melody of part 1 and the style sequence and chord sequence. On the other hand, in the user performance data, the accompaniment sound can be added to the melody with only the data of the parts 1, 2, and 3 without using the style sequence. In such a case, it is necessary to create accompaniment part and percussion part data in parts 2 and 3 of the user performance data. At this time, the desired part can be copied (written) from the style data and edited (created). The work is facilitated and various performance data can be created.

  Note that the parts 2 and 3 of the user performance data and the parts 2 and 3 of the style data correspond to (assign) the same numbered parts. For this reason, when both the user performance data and the style data are reproduced at the same time as in the prior art, the music that has been merged with the overlapping pronunciation channels has been reproduced.

  FIG. 1 is a diagram showing an example of a display screen when editing and creating user performance data in the embodiment of the present invention. This screen is displayed when user performance data (during creation or created performance data) is selected on an initial screen (not shown), and a performance data display window W1 showing the track contents of the selected user performance data is displayed. In addition, a REC switch (REC) SW1, a start switch SW2, a stop switch (STOP) SW3, and a mode select switch (MODE-SELECT) SW4 are displayed as screen switches, and an input box B for selecting a style is displayed.

  In the performance data display window W1, the part names “part 1”, “part 2”, and “part 3” are displayed in the PART-NAME display section. The REC-PART display area is an area for displaying the setting status of the recording mode for each part. In the example in the figure, part 2 displayed with a circle is set to the recording mode, and parts 1 and 3 are displayed. Indicates that the recording mode is not set. Each time the mouse is clicked on the REC-PART display section corresponding to each part (hereinafter simply referred to as “click”), setting / non-setting of the recording mode is switched alternately.

  Recording is started by clicking the REC switch SW1 and clicking the start switch SW2, and the input data is then written to the part in the recording mode state. At this time, the start switch SW2 is displayed as shown in FIG. 2A before the start of recording. However, when the start switch SW2 is clicked, any part 1, 2, or 3 of the user performance data is recorded. If the mode is not set, the display shown in FIG. 2B is displayed. If at least one of the parts 1, 2, and 3 is set in the recording mode, the display shown in FIG. Is displayed. That is, the display mode of the display related to recording differs depending on whether or not the part is designated for recording in the user performance data and when the part is not designated for recording. Therefore, it is possible to intuitively understand whether or not performance data is currently recorded.

  The PERFORMANCE-DATA display section is an area for displaying the contents of each track of performance data in blocks. The horizontal axis from left to right corresponds to the time passage direction, and the time passage direction corresponds to, for example, a measure. A separator line L is displayed. A block in the shape of an oval bar is displayed as a part display area at a location (section) where data is recorded. In this PERFORMANCE-DATA display section, when a desired block is selected by double-clicking, detailed data (not shown) in the selected block is displayed, and the data is in a detailed editing state. For the style sequence and code sequence, each sequence name is displayed and the contents of each sequence data are displayed in blocks.

  In the example of FIG. 1, the track of part 1 indicates that there is no performance data in the first section, and performance data created by the user is recorded in the second and third sections. In the part 2 track, the performance data of part 2 of style A (copied data) is recorded in the first section, the performance data is not recorded in the second section, and the performance data created by the user is recorded in the third section. It shows that. The track of part 3 shows that performance data (copied data) of part 3 of style C is recorded over the first to third sections. The style sequence track indicates that the first section indicates style A, and the second and third sections indicate style B. The chord sequence track indicates that the first section indicates chord A, the second section indicates chords B and C, and the third section indicates chord D.

  In FIG. 1 and the following description, “user created”, “style A”, “style C”, “style A”, “style B”, “chord A”, “chord B”, “chord C” The notation of “chord D” generally represents the performance data name, style name, and chord name. For example, the corresponding name is actually displayed on the display screen (FIG. 1). In particular, chords “A to D” do not correspond to the root of the chord.

  The STYLE-SELECT display part of the input box B is an area for selecting a style in a list menu format. When the down switch SW5 is clicked, a list box is displayed below the input box B. When a style is selected (clicked) from this list, the selected style name is displayed in the input box B. In the example shown in the figure, “Style A” is selected. When this style is selected, a style data display window W2 is displayed beside the STYLE-SELECT display section, and the parts constituting the selected style are displayed as blocks in the style display window W2. In the example shown in the figure, style A is composed of a short part 2 and a long part 3.

  When a desired block (part) in the style data display window W2 is clicked and dragged and dropped at a desired position of the desired part in the PERFORMANCE-DATA display portion of the performance data display window W1, the block dragged to that position is displayed. The part data is pasted. In the example of FIG. 1, the block of part 2 of style A in the style data display window W2 is pasted on the first section of the track of part 2 of the user performance data. Similarly, it is shown that another style C part 3 block is pasted in the first to third sections of the part 3 track of the user performance data.

  The length of the part 2 block of the style data display window W2 is shorter than the length of one section of the PERFORMANCE-DATA display section. In this case, by pasting once in one section, the part within the section 2 is repeated to display performance data and blocks of a length suitable for the section. Also, the track of the part 3 of the user performance data includes the first and second blocks of the part 3 of the style C to be pasted (the same block as the part 3 of the style A in FIG. 1 although not shown). The past performance data and blocks of Part 3 are displayed over the first to third sections by pasting each of the third sections.

  With the above function, data of one desired part of style data can be written in user performance data. Furthermore, as shown in FIG. 1, it is also possible to create user performance data that can sound parts of different styles (style A and style C) in parallel at the same time.

  The stop switch SW3 is a switch that is clicked when stopping the reproduction operation and the recording operation.

  The mode select switch SW4 is a switch that is clicked when switching data to be read out as an accompaniment part. Whether the style data is selected (adopted) or the user performance data is selected (adopted) as the data of part 2 and part 3. Switch. In the user mode, part 2 and part 3 of the user performance data are selected, and in the style mode, part 2 and part 3 of the style data are selected. The mode select switch SW4 is displayed as shown in FIG. 5A in the user mode, and is displayed as shown in FIG. 5B in the style mode, and the display color changes.

  6 to 8 are flowcharts of the performance information editing / playback program executed by the CPU 1, and the control operation of the CPU 1 will be described based on each flowchart. When the main process of FIG. 6 is started, first, in step S1, a process for selecting user performance data to be edited or a new creation, a screen corresponding to the selected or newly created user performance data (FIG. 1). Display processing), initialization processing such as resetting various flags, and the like. Next, it is determined whether or not there is a click event of the mode select switch SW4 in step S2. If there is no click event, the process proceeds to step S4. If there is a click event, the contents of the MODE flag are inverted (1 → 0/0 →) in step S3. 1) and the display mode of the mode select switch SW4 is changed as shown in FIG. 5, and the process proceeds to step S4. The MODE flag is “0” for the style mode, and “1” for the user mode.

  In step S4, it is determined whether or not there is a click event of the start switch SW2. If there is no click event, the process proceeds to step S6. If there is a click event, the contents of the REC flag and the part of the user performance data are set to the recording mode state in step S5. Based on whether it is set or not, the display mode is changed as shown in FIG. Further, “1” is set to the RUN flag, and the performance data reading start is set, and the process proceeds to step S6. The REC flag is a flag indicating whether or not data input during music reproduction is recorded in the performance data. “1” indicates that recording is performed, and “0” indicates that recording is not performed. If the REC flag is “0”, the setting of the recording mode state of the part is not discriminated, and the playback state (FIG. 2B) is always set. The RUN flag is a flag indicating whether or not a later-described reproduction / recording process (interrupt process) is to be started, and “1” indicates that it is started, and “0” indicates that it is not started.

  In step S6, the editing process of FIG. 7 is performed. In step S7, other processes are performed. In step S8, it is determined whether or not the main process is finished. If not finished, the process returns to step S2. finish. In the other process of step S7, the process of setting the RUN flag to “0” by clicking the stop switch SW3, the process of inverting the contents of the REC flag by clicking the REC switch SW1, and the process of clicking the REC-PART display section “ A process of changing the display mode of display / non-display of “O” and a process of changing the recording mode setting / non-setting state of each part based on the click.

  Through the processing in step S5 described above, the display mode of the start switch SW2 can be varied according to the setting / non-setting of the recording mode.

  In the editing process of FIG. 7, in step S11, it is determined whether or not a style is selected on the STYLE-SELECT display unit. If no style is selected, the process proceeds to step S13. If a style is selected, step S12 is performed. The selected style component part is displayed as a block in the style data display window W2, and the process proceeds to step S13. In step S13, it is determined whether or not the block has been moved (click and drag). If there is no movement, the process proceeds to step S17. If there is a movement, the block of style data (part) is moved (from the style data display window W2) in step S14. If it is not a movement of the style data block, the process proceeds to step S16. If it is a movement of the style data block, it corresponds to the movement position in step S15. The pitch information of the part of the moved block is converted based on the contents (chords) of the chord sequencer. For example, in the first section of Part 2 in FIG. 1, the pitch is converted based on the chord A in the first section of the chord sequence track.

  In step S16, the performance data corresponding to the moved block (including the data after the pitch conversion in step S15) is recorded in the corresponding part of the user performance data in FIG. 3 in the data format of the musical event. At the same time, the display on the display unit (FIG. 1) is converted into new user performance data, and the process proceeds to step S17. For example, in the first section of part 2 in FIG. 1, the performance data (style A part 2 data) after pitch conversion is recorded in the musical event data format in part 2 of the user performance data in FIG.

  In step S17, other processing is performed, and the process returns to the main routine. In the other processing in step S17, the detailed data in the block is edited and the block length is expanded or contracted. If the block length is extended, the data is repeatedly recorded for the extended length, and the block length is set. If it is shortened, the excess data is deleted. Further, in this other process, a process of creating and editing a new block (performance data) is performed as in the second and third sections of part 1 or the third section of part 2, for example.

  Through the processes of steps S14, S15, and S16 described above, one part of the style data can be pitch-converted according to the chord sequence of the user performance data and recorded (copied) in the user performance data.

  The reproduction / recording process of FIG. 8 is started only when the RUN flag is “1” (during reproduction) in the interruption process, and it is determined whether or not the MODE flag is “0” in step S21. If the MODE flag is not “0”, it is in the user mode. Therefore, in step S22, the current timing event of each part in the user performance data is processed and the process proceeds to step S24. If the MODE flag is “0”. In the style mode, in step S23, the user performance that does not overlap with the current timing event based on the style and chord sequence specified by the style sequence and the style data parts (parts 2 and 3 in the above example). Processing for the event at the current timing in the data part (part 1) is performed, and the process proceeds to step S24.

  In step S24, it is determined whether or not the REC flag is "1". If the REC flag is not "1", the recording is not in progress, so the process returns to the original routine and if the REC flag is "1". Since recording is in progress, in step S25, information in the input buffer is recorded as performance data events in the recording mode part together with timing data, and the process returns to the original routine. This input buffer is a buffer for sequentially recording information corresponding to a user performance using an electronic musical instrument connected to the MIDI interface 9, for example, and information on the user performance at each input buffer interrupt timing is recorded. The contents of this buffer are cleared every time the recording process to the part in step S25. Thereby, for example, blocks (performance data) of the second and third sections of the part 1 track of FIG. 1 and the third section of the part 2 track can be created.

  Through the processes in steps S22 and S23 described above, the overlapping parts of the user performance data and the style data are not reproduced at the same time, so that the performance intended by the user can be reproduced.

  The content of the part in the user performance data is not limited to that of the embodiment, but it is preferable that a predetermined part type (musical instrument type) is determined in advance for the part number as in the embodiment.

  As a matter of course, the number of parts in the user performance data is not limited to that of the embodiment, and any number may be used as long as it can correspond to the parts in the style data. Further, the correspondence between the part of the user performance data and the part of the style data may be determined as the corresponding part instead of the part number instead of the part set with the timbre set in the part.

  In the embodiment, a plurality of types of style data are stored for each genre of music. However, a plurality of types of style data may be stored for each genre and each variation (intro, fill-in, main, ending, etc.).

  Furthermore, although the style data in the embodiment is stored as part data corresponding to a plurality of parts, a code sequence optimum for the style data may be stored together with the part data. In that case, when a style part (style block) is pasted to the user performance data, the pitch may be converted by a chord sequence in the style data.

  When writing style data to user performance data, it may be possible to write only to parts having the same part number.

  Also, the recording mode may be set for each of the style sequence and the code sequence.

  Further, the style part data stored in each part of the user performance data may be data indicating the corresponding style part data instead of the musical sound event data format.

  Although the above embodiment is configured by a personal computer and software, the present invention can also be applied to an electronic musical instrument. In this case, it is not limited to a keyboard instrument, and may be a string instrument type, a wind instrument type, a percussion instrument type, or the like. Moreover, you may apply to an automatic performance piano. In addition, the sound source device, the sequencer, the effector, and the like are separate devices, and the devices may be connected using communication means such as MIDI or various networks.

  The format of user performance data, style data, style sequence, and chord sequence is “event + relative time” that represents the time of event occurrence as the time from the previous event, and the event occurrence time is absolute in the song or measure. “Event + absolute time” expressed in time, “pitch (rest) + note length” indicating the timing of the event in terms of note pitch and note length or rest and rest length, for each automatic performance minimum resolution Any format may be used such as a “solid method” in which a memory area is secured and a performance event is stored in a memory area corresponding to the time when the event occurs.

  In the above embodiment, the performance information editing / playback program is recorded on the hard disk of the external storage device 5. However, the performance information editing / playback program may be recorded on the ROM 2 particularly in the case of an electronic musical instrument or the like. Furthermore, an external storage device 5 such as a floppy disk, CD-ROM, or MO disk may be used. In this way, new installation, addition or version upgrade of the performance information editing / playback program can be easily performed. Further, a performance information editing / playback program may be recorded on a floppy disk, a magnetic disk (MO) or the like and supplied to the RAM 3 or the hard disk.

  Further, the communication interface 8 and the MIDI interface 9 may be general-purpose interfaces such as RS-232C, USB (Universal Serial Bus), IEEE1394, and the like.
