FIG. 5 is a diagram showing an example of a music data format in the embodiment, and the music data is composed of track data, code sequence data, and style sequence data. The track data stores performance data for a plurality of tracks. The performance data is data in which performance event data and generation timing data indicating the generation timing thereof are stored in the order of reproduction, and are stored in, for example, an SMF (standard MIDI file) format. In the chord sequence data, chord event data representing the type and chord of the chord and generation timing data representing the generation timing thereof are stored in the order of performance progress.
[0021]
In the style sequence data, setting information for timbre settings and the like is recorded, and thereafter, start event data and end event data representing the playback section of the style data are respectively attached to the timing data and stored in the order of performance progress. ing. The start event data is a style name (including a section name) and a genre name. The style data to be read in the reproduction section is designated by the style name and the genre name. And from the start event data to the end event data of one reproduction section corresponds to one block.
[0022]
The style data is a performance data group having one or two measures and stores performance data groups for each genre (style). One style of performance data group is performance data for each of a plurality of sections. The sections are mainly the main section that is used to play the entire song, the intro section that is used to play the prelude of the song, the fill-in section that is used to play phrases in the middle of the song, and the performance of the end of the song. There are several types of sections such as ending sections used for.
[0023]
1 to 3 are diagrams showing an example of editing operation of style sequence data in the embodiment. FIG. 1 (A) shows style sequence data before editing, and FIG. 1 (B) shows editing operation on the editing screen. Show. 2 shows style sequence data after editing (FIG. 2A) and an editing screen after editing (FIG. 2B) in the first example of editing processing, and FIG. 3 shows a second example of editing processing. 3 shows style sequence data after editing (FIG. 3A) and an editing screen after editing (FIG. 3B). It should be noted that the data indicated by a thick frame in FIGS. 2 (A) and 3 (A) indicates that it is inserted data. Also, the horizontal directions in FIGS. 1B, 2B, and 3B correspond to the time axis, and the timing advances from the left to the right in accordance with the flow of music.
[0024]
“Style A start” shown in FIG. 1A is start event data for instructing the start of playback of style data of “style A”, and “end of style A” indicates the end of playback of style data of “style A”. This is the end event data to be instructed. “Start Style B” is start event data for instructing start of reproduction of style data of “Style B”, and “End of Style B” is end event data for instructing end of reproduction of style data of “Style B”. is there. “Timing A, Timing B, Timing C, Timing D” are timing data corresponding to each event data, and are time-sequentially in the order of “Timing A” → “Timing B” → “Timing C” → “Timing D”. It has become.
[0025]
The style A is, for example, the style data of the main section, and the style B is, for example, the style data of the fill-in section. As shown in FIG. 1 (B), the length of the block of the style A (block 1) is long. The length of the block (block 2) is shortened. Then, the style B block 2 is copied (pasted) so as to be superimposed on the style A block 1 by dragging and dropping with the mouse. At this time, the position where the block 2 is overlapped is assumed to be the timing a at the head position of the block 2 and the timing b at the end. In this case, block 2 (style B) is an additional block, and block 1 (style A) is an existing block.
[0026]
The first example shown in FIG. 2 is an example in the case where the rear part of the existing block is not created. When the block 2 is overlapped on the block 1, as shown in FIG. Is displayed as the new block 1 (the front of the existing block), and the block 2 is displayed as the new block 2. Then, the display after the new block 2 (the rear part of the existing block) of the block 1 is erased (data is erased). Then, as shown in FIG. 2A, in the style sequence data, “timing a” and “end style A” are inserted (stored) immediately after “start style A”. Also, “timing a” and “style B start” are inserted immediately after “end of style A”, and “timing b” and “style B end” are inserted immediately after “start of style B”. . Further, “timing B” and “end style A” (see FIG. 1) associated therewith are deleted. Note that the storage area (address) of data after the insertion position other than this is shifted.
[0027]
The second example shown in FIG. 3 is an example of the case where the rear part of the existing block is created. When the block 2 is overlaid on the block 1, as shown in FIG. Front) and new block 2 are displayed. Further, behind this new block 2, the part after the new block 2 of block 1 (the rear part of the existing block) is displayed as one new block 3. Further, as shown in FIG. 3A, the style sequence data includes “timing a” and “style A end”, “timing a” and “style B start” after “style A start”, as described above. “Timing b” and “Style B end” are inserted respectively. Immediately after the “end of style B”, “timing b” and “start of style A” are inserted, and immediately after this “start of style A”, “timing B” and “end of style A” before editing (see FIG. 1) is left as it is.
[0028]
6 to 9 are main part flowcharts of the performance information editing program executed by the CPU 1, and the control operation of the CPU 1 will be described based on the respective flowcharts. The processing of the main operation in FIG. 6 starts when the performance information editing program is started, and ends when the end is instructed. When the performance information editing program is started, an editing screen capable of displaying music data in blocks as shown in FIG. 1 (B) is displayed as an initial screen, and an input instruction from the user is waited for. Is performed.
[0029]
First, in step S1, it is determined whether or not there is an instruction (mouse operation) to overlay a new block (additional block) on an existing block. If there is no corresponding instruction, the process proceeds to step S3. If there is a corresponding instruction, the process of the block insertion operation of FIG. 7 is performed in step S2, and the process proceeds to step S3. In step S3, other processes are performed, and it is determined whether or not an end is instructed in step S4. If no end is instructed, the process returns to step S1, and if an end is instructed, the process ends.
[0030]
In addition, in the other process of step S3, the following processes are performed, for example. A process for the user to select music data to be displayed (opened) on the screen and a process for instructing the start or end of automatic performance (music playback) according to the displayed music data are performed. A process of executing an automatic performance according to the music data is performed. In executing this automatic performance, the performance data of the track data is transmitted to the tone generator circuit 8 to generate a musical sound. Also, various processes such as selectively reading out the style data in accordance with the style sequence data and performing pitch conversion on the style data in accordance with the code sequence data are performed.
[0031]
In the block insertion operation processing of FIG. 7, in step S11, the insertion location (timing) of the additional block in the style sequence data is detected from the state of the mouse operation, and in step S12, the beginning of the editing location (in the above example, Record the end event (timing data and end event data) of the existing block at “timing a”). That is, in the above example, the timing data for “timing a” and the end event data for “style A end” are recorded after the start event data for “style A start” corresponding to “timing A”.
[0032]
Next, in step S13, the start event and end event of the additional block are recorded following the recorded end event. That is, as shown in FIG. 2A or FIG. 3A, timing data and start event data, timing data and end event data of an additional block are recorded. In step S14, the rear process of the existing block shown in FIG. 8 or FIG. 9 is performed to return to the original routine.
[0033]
FIG. 8 is a first example of the existing block processing corresponding to FIG. 2. In step S21, timing data corresponding to the original end event data of the existing block is deleted, and in step S22, new style sequence data is created. Based on this, the front part of the existing block and the additional block are displayed on the screen, and the process returns to the original routine.
[0034]
FIG. 9 shows a second example of the existing block processing corresponding to FIG. 3, and it is detected in step S31 whether a part of the existing block remains behind the added block. Whether or not this part remains is detected by, for example, comparing the timing data corresponding to the end event data of the existing block and the rear end position (corresponding timing) of the additional block superimposed on the existing block. it can. Next, in step S32, it is determined whether or not a part of the existing block remains behind the additional block. If so, the process proceeds to step S33, and if not, the process proceeds to step S35.
[0035]
In step S33, following the end event data of the additional block, start event data for the same content (same style data) as the existing block is recorded together with the same timing data as the end event data of the additional block. Next, in step S34, based on the new style sequence data, the existing block front part, the additional block, and the existing block rear part are displayed on the screen, and the process returns to the original routine. The end event data at the rear of the existing block is used as it is because the end event data of the original existing block remains.
[0036]
In step S35, the original end event data of the existing block and the corresponding timing data are deleted, and in step S36, the existing block front part and the additional block are displayed on the screen based on the new style sequence data. Return to the original routine.
[0037]
By the above processing, the style sequence data is edited and the display is changed as shown in FIG. When automatic performance is performed using the edited style sequence data, in the case of FIG. 2, the style A is selected by the start event data of “style A start” at the timing A, and the style A (from the timing A to the timing a ( The front of the existing block is played back. At timing a, style B is selected by the start event data of “style B start”, and style B (additional block) is reproduced from timing a to timing b. In the case of FIG. 3, style A (existing block front) and style B are reproduced in the same manner as described above, but at the timing b when the reproduction of style B ends, the style is started by the start event data of “style A start”. A is selected, and style A (the rear part of the existing block) is reproduced from timing b to timing B.
[0038]
In this way, a performance suitable for the display example of FIG. 2 (B) or FIG. 3 (B) is performed, and the end event data of the existing style before editing is deleted when the rear part of the existing style is not created. (S21 in FIG. 8), unnecessary data is not included in the style sequence data, and accurate style sequence data suitable for display contents is obtained.
[0039]
In the example of FIG. 1, the case where the existing block and the additional block are in the same style sequence data has been described. However, the additional block may be selected from other style sequence data, a database, or the like.
[0040]
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. 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.
[0041]
The format of the style data is “event + relative time” that represents the time of event occurrence as the time from the previous event, and “event + absolute” that represents the time of event occurrence as absolute time in the song or measure. “Time”, “pitch (rest) + note length”, which indicates the timing of the event in terms of note pitch and note length, or rest and rest length, memory area for each automatic performance (playback function) minimum resolution Can be used in any format, such as a “solid method” in which performance events are stored in a memory area corresponding to the time at which the event occurs.
[0042]
The performance information editing program has been described on the case where the performance information editing program is recorded on the hard disk of the external storage device 5 and expanded on the RAM 3, but may be recorded on the ROM 2 particularly in the case of an electronic musical instrument or the like. Further, an external storage device 5 such as a flexible disk, CD-ROM, or MO disk may be used. In this way, new installation, addition or version upgrade of the performance information editing program can be easily performed. Further, a performance information editing program may be recorded on a flexible disk, a magnetic disk (MO) or the like and supplied to the RAM 3 or the hard disk. Further, the external storage device 5 may be a device for using various types of media other than those described above.
[0043]
In addition, since the communication interface 10 is connected to the server computer via the communication network 15 as described above, if the performance information editing program and various data are not stored in the hard disk device, the performance information editing program, Various data may be downloaded. In this case, the terminal device (personal computer) of the present embodiment serving as a client transmits a command requesting download of a control program and various data to the server computer via the communication interface 10 and the communication network 15. Upon receiving this command, the server computer distributes the requested program and various data to the terminal device of the present embodiment via the communication network 30, and the terminal device of the present embodiment receives these commands via the communication interface 10. Downloading is completed by receiving programs and various data and storing them in the hard disk.
