[0020]
FIG. 2 is a diagram showing an example of each data format of performance data and score symbol data. In the present embodiment, performance data and score symbol data are generated individually.
[0021]
In the figure, the performance data is basically composed of a plurality of sets of sequences (n = 1, 2,...) Including event data 22n and timing data 21n indicating the generation timing of the event. End data 23 indicating the end of the data is arranged at the end of the performance data.
[0022]
Each timing data 21n represents the generation timing of the event data 22n positioned immediately after it, as an integer value in units of musical sound resolution (for example, 96th note length). There are various methods for expressing the generation timing, such as the method using the relative time from the previous event data and the method using the absolute time from the beginning of the song or measure. May be adopted.
[0023]
Each event data 22n is composed of data indicating a pitch, data indicating sound generation / mute, and data (not shown) indicating velocity. Note that when the event data instructs to mute, the data indicating the velocity is not usually required. In this case, the data indicating the velocity may not be included in the event data.
[0024]
The musical score symbol data is composed of a plurality of sets (n = 1, 2,...) Of symbol data 32n and position data 31n indicating the display position of the symbol on the score. End data 33 indicating the end of the data is arranged at the end.
[0025]
The position data 31n is expressed by a bar number and a display (pasting) position (XY coordinate) in the bar. Of course, this expression method is merely an example, and the present invention is not limited to this as long as the display position on the score can be uniquely expressed. For example, a method of expressing the position of the horizontal axis of a musical score with timing data, such as performance data, and expressing the position of the vertical axis with a pitch (in this case, including not only a musical tone but also an intermediate pitch) Is mentioned.
[0026]
Examples of the symbol data 32n include a repetition symbol indicating that performance data in a predetermined range in front (for example, one measure before one measure) is repeated as it is, a strength symbol indicating the strength of a sound, a tempo symbol indicating a tempo, and the like. .
[0027]
In the automatic performance device of the present embodiment, when performing automatically, it is performed based on performance data, and when displaying a score, notes are displayed based on the performance data, and symbols other than the notes are displayed. Is displayed based on musical score data.
[0028]
The control process executed by the automatic performance apparatus configured as described above will be described first with reference to FIG. 3 and then in detail with reference to FIGS.
[0029]
The automatic performance device of the present embodiment has a performance data creation / editing mode for creating performance data or editing the created performance data, and when the performance data creation / editing mode is selected, As shown in FIG. 3A, the staff notation display unit and the control data display unit are displayed on the display device 7 as a pair.
[0030]
The staff notation display unit displays a staff notation and displays a musical score symbol (including a note) pasted by the operator on the staff notation.
[0031]
The control data display unit displays the sound generation period (key-on timing and gate time or key-off timing) and velocity of the key-on event. In the control data display section of FIG. 3A, four bar-shaped figures 41k (k = 1, 2, 3, 4) are displayed. Each bar-shaped figure 41k has a velocity value corresponding to the height. The width indicates the pronunciation period.
[0032]
In the musical score display state of FIG. 3A, when the operator pastes a repetition symbol indicating that the performance data for one measure before one measure is repeated as it is in the staff notation display portion, as shown in FIG. 3B. In addition, a repetitive symbol 43 is displayed at the pasting position, and the contents of a predetermined type of control data (the sound generation period and velocity of the key-on event) of the measure, specifically, four bar shapes are displayed on the control data display section. A figure 42k (k = 1, 2, 3, 4) is displayed. In this case, as described above, the pasted symbol repeats the performance data of the previous measure as it is, as described above, and therefore the control data display section at the position of the repeated symbol displays the measure data of the previous measure. The same display contents as in the control data display section are displayed.
[0033]
In addition, when the operator edits the performance data in the performance data creation / edit mode, all the repeated symbols that have already been pasted are searched, and the control data display unit displays the performance data referenced by the repeated symbols. The contents of the specific type of control data in the bar are displayed again.
[0034]
Next, this control process will be described in detail.
[0035]
The automatic performance device of the present embodiment is a control process that characterizes the present invention.
(1) Repeated symbol pasting processing (2) Performing two types of control processing, performance data editing processing.
[0036]
FIG. 4 is a flowchart showing the procedure of the repeated symbol pasting process (1), and FIG. 6 is a flowchart showing the procedure of a search & copy process subroutine executed in the repeated symbol pasting process.
[0037]
FIG. 5 is a flowchart showing the procedure of the performance data editing process (2). The search and copy processing subroutine of FIG. 6 is also executed in this performance data editing process.
[0038]
Hereinafter, (1) the repeated symbol pasting process and (2) the performance data editing process will be described in order.
[0039]
First, when the operator pastes a repeated symbol on an arbitrary position on the staff, for example, at a position shown in FIG. 3B (step S1), as shown in FIG. After the position data and the repeated symbol data corresponding to the pasted position are inserted (step S2), a search & copy processing subroutine is executed (step S3).
[0040]
In the search and copy processing subroutine, a range corresponding to the length of the repeated symbol is searched before the timing corresponding to the position data of the repeated symbol in the performance data (step S21), and the found event data and its timing data are searched. Are copied backward from the timing corresponding to the position data of the repeated symbols (step S22). That is, in FIG. 3B, the operator pastes a repetition symbol that repeats the performance data for one measure before one measure. In this case, when search and copy processing is executed, FIG. As shown in FIG. 8B, the performance data for one measure before one measure, that is, the event data and its timing data within the range are searched, and as shown in FIG. It is copied backward from the timing corresponding to.
[0041]
Then, based on the copied performance data, a predetermined type of control data is displayed on the control data display section (step S4).
[0042]
In this way, when a repeated symbol is pasted, the control data display section displays the content of the specific type of control data for that measure, so the operator can visually view the performance data at the position corresponding to the repeated symbol. Can be confirmed.
[0043]
Next, when the operator edits the performance data (step S11), the repetition symbol included in the musical score data is searched from the top of the data (step S12), and the search & copy process is performed each time the repetition symbol is found. A subroutine is executed (steps S13 → S14 → S15 → S13).
[0044]
When no repeated symbol is found, a predetermined type of control data is displayed on the control data display unit based on the performance data (step S16).
[0045]
As a result, even if the performance data in the place where the repeated symbol is affected changes (addition, deletion, change, etc.) after the repeated symbol is pasted, this is reliably reflected in the repeated portion.
[0046]
In the present embodiment, the sound generation period and velocity of the key-on event are given as the predetermined type of control data displayed on the control data display unit. However, the pitch is added to each of the bar-like shapes shown in FIG. The pitch may be displayed as characters in or near the figures 41k and 42k. Further, only one of these three types of control data or two types arbitrarily combined may be displayed.
[0047]
In the present embodiment, the stave display unit and the control data display unit are displayed on the display device 7 at the same time. However, the present invention is not limited to this, and a stave display mode and a control data display mode are provided. Only one of them may be displayed by switching to the mode. Further, a mode for simultaneously displaying a staff score display and a control data display may be added to these two modes, and the three modes may be arbitrarily switched.
[0048]
In addition, the display mode of the control data display unit is not limited to the bar-shaped figure as in the present embodiment, and other modes such as a mode in which the contents of event data are displayed in a list or a mode in which a piano roll is imitated are adopted. May be.
[0049]
Further, in the present embodiment, when the performance data is edited, all the repeated symbols included in the corresponding musical score symbol data are searched, and the performance data referred to by the repeated symbols is copied again. However, the present invention is not limited to this, and only the repeated symbols that refer to the performance data actually affected by the editing may be searched, and only the performance data referenced by the repeated symbols may be copied again. For example, after searching for repeated symbols after editing, the performance data referenced only by the first found repeated symbol is copied, or the performance data referenced by the first found repeated symbol is edited. There is a method of determining whether or not to be influenced and copying the performance data only when the result is affected.
[0050]
In addition, as the repetition symbol, only the one indicating that the performance data for one measure before the first measure is repeated as an example has been described as an example, but this is only for convenience of explanation, and two measures, three measures, etc. Another measure unit may be employed, or a unit having a section shorter than the measure may be employed. If a repeated symbol having a different display mode is provided for each section having a different length so that the operator can select and paste one of them, the operability is further improved.
[0051]
Furthermore, in the present embodiment, the performance data and the musical score data are generated individually. However, the performance data and the musical score data may be included in the performance data. In this case, as described above, the position data indicating the display position of the symbol data is preferably adopted in the same format as the timing data of the performance data because the control process can be easily performed. It is not necessary to limit to this. In the present embodiment, it is assumed that the performance data and the musical score data are generated by the operator inputting one by one. Of course, the ready-made data is used and edited appropriately. You may do it.
