Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for designating a performance section of a displayed score, and an apparatus for performing a designated section of a displayed score.
[0002]
[Prior art]
Some electronic musical instrument display functions and musical score display devices on PCs are used for automatic performances, for user performance practice with respect to model performances, or for scoring For this reason, there are some which have a function of not only automatically playing the entire displayed score on the apparatus side but also playing a range designated by the user.
[0003]
For example, a configuration has been disclosed in which a user designates a specific measure on a score displayed on a score display section and plays a score within that range (see Patent Document 1 described later).
[0004]
In such a prior art configuration, for example, when a score display as shown in FIG. 14 is displayed on the display means, an arbitrary performance as shown in FIG. 15 is performed by a cursor on the display screen and a pointing device such as a mouse. As shown in FIG. 16, the start position and the performance end position are designated as performance section information. As shown in FIG. 16, the information [S (n) is the data indicating the performance start position and E (n) is the performance stop position. Is stored in the data storage means.
[0005]
Therefore, the performance start position and the performance end position can be designated by changing the data content of the performance section information other than the position designation by the pointing device.
[0006]
[Patent Document 1]
JP 2000-56756 A (refer to claim 4)
[0007]
[Problems to be solved by the invention]
In the above prior art configuration, the performance start position and the performance end position are specified in units of measures, but it may be performed in units of time.
[0008]
When the above pointing device is used and positioned, the performance start position and performance end position for a measure can be specified by specifying the pointing device on an arbitrary measure. Will be able to do. In this case, the operability is improved, but it is difficult to specify a fine performance section such as a time unit.
[0009]
In other words, even if it is attempted to specify the performance interval in units of time, as specified on a specific note, etc., if the specification in units of measures as described above is executed as it is, the measure to which the note belongs is changed. All are specified, and such a detailed specification cannot be made.
[0010]
On the other hand, in a configuration in which the performance interval in time units, such as specified on specific notes, can be specified in detail, the specified specific notes, etc., are always specified, and the performance interval like a measure unit is always specified. Rough specification becomes difficult.
[0011]
In addition, the nerve is used for the designation, and conversely, the operability of the pointing device is deteriorated. In particular, with regard to operability, a pointing device is not always appropriate in terms of the user interface, such as requiring a certain degree of skill to make detailed designations such as time units on a musical score, and being a task that uses nerves. It wasn't.
[0012]
The present invention was devised in view of the above problems, and by performing appropriate improvements related to a user interface such as a pointing device, the performance section can be specified in units of measures with a rough specification operation or a simple specification operation. It is intended to provide a display musical score performance section specifying device and a display musical score specified section performance apparatus which can specify a performance section in time units by a detailed designation operation or a simple designation operation.
[0013]
[Means for Solving the Problems]
Therefore, the structure of the section designating device for display musical score performance according to the present invention is as follows.
Data storage for storing musical score data including at least musical note data, symbol data, and data necessary for musical score display, and musical score range delimiter data including range delimiter data of start bar position, end bar position, start time position, and end time position Means,

[0015]
In the configuration of the first aspect, the speed detected by the speed detecting means is detected by the range delimiter data generating means. Predetermined speed If it is faster, the start position and end position according to the designation are stored in the data storage means as the start bar position and end bar position, and the detection speed is Predetermined speed If it is later, the start position and end position according to the designation are stored in the data storage means as the start time position and end time position, and the musical score range stored in the data storage means by the performance data output means The musical score data in the delimiter data is output as performance data. Accordingly, in the rough designation operation in which the speed of detection is increased only by the speed detection means (from the designation start position designated by the position designation means to the designation end position) being detected by the speed detection means, in the measure unit, The performance section can be specified with a time signature, and the performance section can be specified in units of time by a fine specification operation that slows down the detection speed.
[0016]
Further, the configuration of claim 2 is not a configuration for discriminating the designation of the performance section in measure units and the designation of the performance section in time units from the difference in detection speed as in the configuration of claim 1 above. Depending on the type of click operation such as simple click or double click, or there are two or more click buttons, depending on which button is clicked, the performance interval in measure units and the performance interval in time units Is determined.
[0017]
That is, the configuration of the section designating device for display musical score performance of claim 2 is as follows:

A range delimiter data generating means for storing each position in the click operation order in the data storage means as a start time position and an end time position,
Performance data output means for outputting the musical score data in the musical score range delimiter data stored in the data storage means as performance data; and
It is characterized by having.
[0018]
In the above configuration, when the specific type of click operation detected by the click detection unit or the click operation of the specific click button is accompanied by a range specification from the specification start to the specification end, the range delimiter data generation unit The start position and the end position related to the range specification are stored in the data storage means as the start bar position and the end bar position, and the click operation different from the type detected by the click detection means or the click different from the above When the button click operation is performed on the score, the range delimiter data generation means stores the respective positions in the click operation order in the data storage means as the start time position and the end time position, and the performance data The output means plays the score data in the score range delimiter data stored in the data storage means. And to use the data will be output. Therefore, depending on what kind of click operation, such as simple click or double click, or there are two or more click buttons, and which button is clicked, the performance section can be specified in units of measures. The performance section can be specified in time units.
[0019]
As described above, in the configurations of claims 3 to 5, not only the performance data output means but also a musical tone generation means is provided, and a performance apparatus such as an electronic musical instrument can be realized.
[0020]
Among them, the configuration of the display score designation section performance device according to claim 3 is defined by the configuration of claim 1, in which a configuration including a musical tone generation means is provided instead of the performance data output means.
[0021]
That is, the configuration of claim 3 is

[0022]
The configuration of claim 4 is based on the above configuration of claim 3, and when the score display means is constituted by a touch panel and also serves as the configuration of position specifying means, the score displayed on the touch panel is displayed. When the first touch is made, The position specification specified by the position specification means is regarded as the start time position in the range delimiter data generation means. After that, the detection speed by the speed detection means Predetermined speed In the case of faster speed, the position initially regarded as the start time position is changed to the start bar position, and the designated end position is stored in the data storage means as the end bar position.
[0023]
This is because a touch panel provided in an electronic musical instrument or the like serves as a display means for displaying various musical scores and the like (score), and at the same time serves as a position specifying means such as the pointing device. The first touch on the panel is different from a normal pointing device consisting of a cursor and a mouse, so it does not know whether it corresponds to the cursor or the click operation of the mouse. First touch When there was Is The position designation designated by the position designation means and the start time position in the range delimiter data generation means When the touch part moves after that, the movement speed is detected, and the position at the time of touch-off (designated end position) at the position (designated end position) at the time of touch-off, the performance in units of measures The specification of the section and the specification of the performance section in time units are discriminated.

[0048]
Next, a flowchart of a main routine of the electronic piano 100 according to the present embodiment will be described.
[0049]
FIG. 6 shows a flowchart of a main routine of the electronic piano 100. First, when the power is turned on, the CPU 110, RAM 130, scan circuits 141 and 151, the panel display control circuit 142, the waveform data reading unit of the musical tone generation circuit 160, and the like are initialized (step S101). Thereafter, panel event processing (step S102), keyboard event processing (step S103), automatic performance processing (step S104), and other processing (step S105) are repeated. The panel event processing and automatic performance processing will be described later.
[0050]
FIG. 7 is a flowchart of the panel event process shown in step S102 of FIG.
[0051]
In the panel event processing shown in the figure, various displays are made at the beginning, and there is a mode selection screen, and the range delimiter performance mode in the automatic performance mode is also displayed, and these modes are selected. A selection display of musical score data necessary for the display is also displayed (step S201).
[0052]
Here, the user touches the display on the touch panel 140 to select the mode and the score data. The CPU 110 checks whether or not the score data is selected (step S202). If there is no selection (step S202; N), the process returns to step S201.
[0053]
On the contrary, when the musical score data is selected (step S202; Y), it is checked whether or not the range separation performance mode is selected in the mode selection display (step S203). When the mode is not selected (step S203; N), other mode processing (the automatic performance mode is usually performed because there is a score selection and the range separation performance mode is not selected) (step S216).
[0054]
Conversely, when the range delimiter performance mode is selected (step S203; Y), the score to be played in the mode is displayed (step S204).
[0055]
Then, on the score displayed on the touch panel 140, it is checked whether or not the user has touched (touched on) (step S205). If there is no touch-on (step S205; N), this check is repeated.
[0056]
On the other hand, if there is a touch-on (step S205; Y), the position at the time of touch-on in the score displayed on the touch panel 140 is acquired (step S206).
[0057]
The moving speed between the moving trajectories is detected by the speed detecting means 4 until the user releases the finger from the touch panel 140 at an arbitrary position (step S207).
[0058]
Then, it is checked whether or not the touch panel 140 is touched off (step S208). If the touch is not off (step S208; N), the process returns to step S207.
[0059]
On the other hand, if there is a touch-off (step S208; Y), the position at the time of touch-off in the score displayed on the touch panel 140 is acquired (step S209).
[0060]
Then, the speed threshold set by the speed threshold setting means 50 and stored in the RAM 130 are compared with the detected moving speed by the range delimiter data generating means 5 to check whether the moving speed is equal to or higher than the speed threshold. (Step S210).
[0061]
If the moving speed is equal to or higher than the speed threshold (step S210; Y), each bar position located when the touch-on / touch-off is performed is acquired (step S211), and the musical score range delimiter data is generated by the range delimiter data generation means 5. The start bar position information and the end bar position information are stored in the storage area 132 (step S212).
[0062]
On the other hand, if the moving speed is not equal to or greater than the speed threshold (step S210; N), each beat position located when the touch-on / touch-off is performed is acquired (step S213), and the score range is generated by the range delimiter data generation means 5 The start time position information and the end time position information are stored in the delimiter data storage area 132 (step S214).
[0063]
After the process of step S212 or step S214 is completed, it is checked again whether there is a touch-on (step S215). If there is a touch-on again (step S215; Y), the process returns to step S206 and the above processing is repeated. On the other hand, if there is no touch-on again (step S215; N), the panel event process ends and the process returns to the main routine.
[0064]
FIG. 8 is a flowchart of the automatic performance process shown in step S104 of FIG.
[0065]
In the automatic performance process shown in the figure, it is first checked whether or not the range delimiter performance mode is set (step S301).
[0066]
If it is not the range delimiter performance mode (step S301; N), the process is performed as another automatic performance mode (such as a normal automatic performance mode in which no range delimitation is specified) (step S309).
[0067]
On the contrary, if it is the range delimiter performance mode (step S301; Y), the score data and the score range delimiter data are read from the score data storage area 131 and the score range delimiter data storage area 132 of the data storage means 1 (step S302). ).
[0068]
Then, it is checked whether or not there is start bar position information and end bar position information from the score range delimiter data (step S303). If there is no such information (step S303; N), the process proceeds to step S305.
[0069]
On the contrary, if there is such information (step S303; Y), the start bar position information and the end bar position information are set as musical score range delimiter data to be automatically played (step S304).
[0070]
Next, it is also checked whether or not there is start beat position information and end beat position information from the musical score range delimiter data (step S305). If there is no such information (step S305; N), the process proceeds to step S307.
[0071]
On the contrary, if there is such information (step S305; Y), the start time position information and the end time position information are set as musical score range delimiter data to be automatically played (step S306).
[0072]
And, as musical score range delimiter data, (start bar position information and end bar position information) and / or (start time position information and end time position information) (one or both of these information may be used) automatically.
