Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device,
More specifically, the present invention relates to an automatic performance device suitable for reproducing music data having a large amount of set-up data arranged at the beginning thereof.

[0002]

2. Description of the Related Art Generally, in music data reproduced by an automatic performance device, a large amount of set-up data (a parameter for setting a tone color, etc.) is set at the beginning of the first measure of the music. Is data that needs to be set in the sound source in advance before performing actual tone generation / silence processing based on performance data, which is data for performing tone generation / silence processing. There is.

For example, in the MIDI standard music data, a large amount of set-up data for controlling a sound source such as a program change and a control change is provided at the beginning of the first measure of the music. It is arranged.

[0004]

However, in the case where the automatic performance device reproduces the music data in which a large amount of set-up data is arranged at the beginning of the first measure of the music, the automatic performance device generates a large amount of data. The sound source to which the set-up data of is sent is used for processing this large amount of set-up data (based on program changes and control changes, controlling the sound source such as setting the tone color). It was supposed to take time.

Therefore, when the performance data exists at the first beat of the first measure of the music, the performance of the first beat of the first measure is performed due to the processing of the set-up data in the sound source. There is a problem in that the sounding timing of the musical sound based on the data is delayed, and the sounding of the time length specified by the performance data cannot be secured.

For example, as shown in FIG. 8 (a), a large amount of set-up music is set at the beginning (first beat) of the first measure of the music.
When the data A is arranged and the performance data B for instructing the pronunciation of the quarter note at the first beat exists, it takes time for the sound source to perform the processing of the setup data A such as the tone setting processing. Is set, and the sound generation timing at which the sound source actually produces a musical sound based on performance data B is set
The processing time of the update data A was delayed by (Δt) seconds.

That is, originally, as shown in FIG. 8C, a quarter note based on the performance data B has to be pronounced at the beginning of the first beat of the music, but in reality As shown in FIG. 8 (d), the set-up data A is to be sounded with a delay of processing time (Δt) seconds, and it is not possible to secure sounding for a time length of a quarter note.
The actual duration of pronunciation was shorter than the time interval of quarter notes.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to set a large amount of sets at the beginning of the first measure of the music.
Even when playing music data that has update data, the time length of the musical tone specified by the performance data is not shortened due to the processing of the set-up data in the sound source. The present invention aims to provide an automatic performance device.

[0009]

In order to achieve the above object, an automatic performance device according to the present invention comprises a storage means for storing music data and a reproduction means for reproducing the music data stored in the storage means. In an automatic performance device that sequentially reproduces the music data stored in the storage means by the reproduction means, the reproduction start of predetermined data in the music data stored in the storage means is shifted by a predetermined time. did.

[0010]

[Operation] Since the reproduction start of the predetermined data in the music data can be shifted for a predetermined time, the reproduction start of the music data excluding the set-up data is shifted by a predetermined number of measures, and the sound source is set. After the processing of the update data, the sound source can be made to generate the actual musical sound based on the music data excluding the set-up data.

Therefore, since the actual tone generation of the musical tone in the sound source is not affected by the processing time of the set-up data, it is possible to secure the tone generation of the musical tone with the accurate time length designated by the music data.

[0012]

(Bar number setting switch) When the bar number setting switch is operated, a bar number setting processing routine to be described later is started,
It will be set to the measure number setting mode, and up S
As the number of moving bars, which is the number of bars by which the music data other than the set-up data set by the parameter setting processing routine (described later) in the edit execution processing routine (described later) is moved by operating W and the down SW, It can be set by selecting "1" or "2".
Measure number display area 20a of the display unit 20
"1" or "2" is displayed as the set number of moving measures. FIG. 2 shows a state in which “1” is set as the number of moving measures.

(Parameter setting SW) Parameter setting S
When W is operated, a parameter setting processing routine, which will be described later, is started and the parameter setting mode is set. By operating the up SW and the down SW, the parameters (program change, track) previously set in the ROM 14 are operated.・ Volume etc. is called in sequence, and edit data (Edit Da) of the display unit 20 is displayed.
ta) It can be displayed in the display area 20b. These parameters are stored in a loop in the ROM 14, and when the down SW is operated, the up S
It can be called in order from the direction opposite to the operation of W. Thus up SW and down S
The parameter called by the operation of W and displayed in the edit data display area 20b is registered in the RAM 16 as set-up data by operating the enter SW. At this time, the edit data display area 20b
The display of is reversed, indicating that it has been registered as set-up data. Figure 3 shows the program change (Program Change) set up.
The state set as data is shown. If the enter SW is operated again for the parameters registered as set-up data, the set-up
The registration as data is deleted, and the display in the edit / data display area 20b is also restored.

(Edit execution SW) Edit execution S

(Re-edit execution SW) When the re-edit execution SW is operated, a re-edit execution processing routine, which will be described later, is activated, and the set-up data set by the parameter setting processing routine moved by the edit execution SW is activated. A process of restoring the music data other than the above is executed.

The operation and operation of the above-described automatic musical instrument according to the present invention will be described with reference to the flow charts shown in FIGS.

As described above, the resolution of the automatic performance device according to the present invention is up to quarter notes, and FIG. 7 shows an example of music data.

The music data shown in FIG. 7 is a music of "quarter beat", and one bar is composed of four quarter notes. The concept of time of one bar is recorded as a relative time t (the time interval between the collection of data which should be theoretically processed on the same time (hereinafter, this is referred to as a block)). To do. Therefore, at the beginning of the music data, the relative time t is "0", and the relative time between blocks is "1". Note that the total relative time T records a value obtained by accumulating the relative time t, and is a position display of the elapsed time from the start of the performance.

In the following description, for ease of understanding, the case of processing the music data shown in FIG. 7 will be described.

First, the bar number setting processing routine which is activated by the bar number setting switch will be described.

FIG. 3 shows a bar number setting processing routine,
When the measure number setting switch is operated, the measure number setting mode is entered (step S302).

When the measure number setting mode is entered, the processing is divided depending on whether the up SW or the down SW has been operated. First, a process when the up SW is operated will be described.

The up SW sets the number of moving measures to "1".
It is an operator for increasing the number, and when the up SW is operated (step S304), the process proceeds to step S306.

In step S306, it is determined whether or not the setting is "1". To set the number of moving measures,
Since it is prepared only for "1" or "2", if the determination result of step S306 is negative (N), that is, if the number of moving measures is already set to "2", the subsequent processing is not performed. Then, this bar number setting processing routine is ended.

On the other hand, if the determination result of step S306 is affirmative (Y), that is, if the number of moving measures is set to "1", the process proceeds to step S308. In step S308, the setting of the number of moving measures is increased by "1" (that is, the setting of the number of moving measures becomes "2"), and this measure number setting processing routine is ended.

Therefore, when the up SW is operated, "2" is set as the number of moving bars.

Next, the processing when the down SW is operated will be described.

The down SW sets the number of moving measures to "1".
This is a manipulator for decreasing, and when this down SW is operated (step S310), the process proceeds to step S312.

In step S312, it is determined whether the setting is "2". To set the number of moving measures,
Since it is prepared only for "1" or "2", if the determination result of step S312 is negative, that is, if the number of moving measures has already been set to "1", this processing is performed without performing the subsequent processing. The measure number setting routine ends.

On the other hand, if the determination result of step S312 is affirmative, that is, if the number of moving measures is set to "2", the process proceeds to step S314.

In step S314, the setting of the number of moving measures is decreased by "1" (that is, the setting of the number of moving measures becomes "1"), and this measure number setting processing routine is ended.

Therefore, when the down SW is operated, "1" is set as the number of moving bars.

Next, the parameter setting processing routine started by the parameter setting SW will be described.

FIG. 4 shows a parameter setting processing routine. When the parameter setting SW is operated, the parameter setting mode is entered (step S402).

When the parameter setting mode is entered, the up S
The processing is divided depending on whether W is operated or the down SW is operated. First, a process when the up SW is operated will be described.

The up SW is an operator for sequentially calling up parameters that can be set as set-up data, and when the up SW is operated (step S4).
For 04), the process proceeds to step S406.

In step S406, the parameters are called in the order registered in the ROM 14 in advance. When the process of step S406 ends, the process proceeds to step S408.

Next, the processing when the down SW is operated will be described.

The down SW is an operator for calling up parameters that can be set as set-up data in the reverse order of the up SW. When the down SW is operated (step S410), the step S412
Go to.

In step S412, the parameters are called in the reverse order to the order registered in the ROM 14 in advance. When the process of step S412 ends, the process proceeds to step S408.

In step S408, it is determined whether the enter SW has been operated. If the determination result in step S408 is negative, that is, if the enter SW is not operated, the process returns to step S404 or step S410 to perform the process for the next parameter, and the above process is repeated.

On the other hand, if the determination result in step S408 is affirmative, that is, if the enter SW is operated, the process proceeds to step S414, and the parameter called at the time of operating the enter SW (called in step S406 or step S412). Parameter) has already registered the setting as set-up data.

The determination result of step S414 is positive,
That is, when the parameter called in step S406 or step S412 has already registered the setting as set-up data, step S4
Proceed to 16.

At step S416, step S406.
Alternatively, the setting registration as the setup data is deleted for the parameter called in step S412, and this parameter setting processing routine is ended.

On the other hand, the determination result of step S414 is negative, that is, step S406 or step S412.
If the parameter called in step S1 is not registered as the setup data, step S
Proceed to 418.

In step S418, step S406.
Alternatively, the setting as the setup data is registered for the parameter called in step S412, and this parameter setting processing routine is ended.

Further, a process of moving the music data other than the set-up data set by the parameter setting processing routine and started by the operation of the edit execution SW by the number of moving measures set by the bar number setting routine. The edit execution processing routine for executing the will be described.

FIG. 5 shows an edit execution processing routine. When the edit execution SW is operated, the edit mode is entered (step S502).

When the edit mode is entered, step S
In 504, all the data registered as set-up data in step S418 out of the music data in “Relative time total T = 0” shown in FIG. 7 are located in order from the beginning of the music data. Then, change the music data in order. When the process of step S504 ends, the process proceeds to step S506.

In step S506, whether the number of moving measures set by the measure number setting routine is "1" or "2".
To determine if.

If it is determined in step S506 that the number of moving measures set by the measure number setting routine is "1", the process proceeds to step S508 and step S41.
Among the data (performance data) other than the data registered as set-up data in 8, the relative time t of the data located at the very beginning is “4” (time value for one bar) Is added, and this edit execution processing routine ends. That is, a process of moving one bar (hereinafter, referred to as "one bar edit process") is executed for data other than the data registered as the set-up data in step S418.

Therefore, when reproducing the music data shown in FIG. 8A, as shown in FIG. 8B, the set-up data A registered as the set-up data in step S418 is , The first of the first measure
The performance data B, which is still located at the beginning of the beat, but which instructs the pronunciation of the quarter note of the first beat of the first measure, is moved to the first beat of the second measure.

Therefore, even if the sound source takes a long time to process the set-up data A, the actual pronunciation based on the performance data B starts from the first beat of the second measure, so that the performance data The sound generation time of the musical sound designated by B is not shortened.

On the other hand, if it is determined in step S506 that the number of moving measures set by the measure setting routine is "2", the flow advances to step S510 to register the data registered as set-up data in step S418. Among the data (performance data) other than the above, “8” (2
The time value of the measure) is added, and this edit execution processing routine is ended. That is, a process of moving two measures (hereinafter referred to as "two-bar edit process") is executed for data other than the data registered as the set-up data in step S418.

Therefore, although not shown in particular, FIG.
In the case of reproducing the music data shown in, the set-up data A registered as the set-up data in step S418 remains located at the beginning of the first beat of the first measure, The performance data B instructing the pronunciation of the quarter note of the first beat of one measure is moved to the first beat of the third measure.

Therefore, even if the sound source takes a long time to process the set-up data A, the actual pronunciation based on the performance data B starts from the first beat of the third measure. The sound generation time of the musical sound designated by B is not shortened.

Next, a re-editing execution processing routine will be described, which is started by the operation of the re-editing execution SW and executes processing for restoring the music data moved by the edit-execution SW to the original state.

FIG. 6 shows a reedit execution processing routine. When the reedit execution SW is operated, the reedit mode is entered (step S602).

When the re-edit mode is entered, the position of the performance data located at the very beginning is checked in step S604, and if "t <8", the music data for which one-bar edit processing has been executed or one-bar edit is executed. It is determined that the music data has undergone neither the processing nor the two-bar edit processing, and the process proceeds to step S606.

On the other hand, if "8≤t", it is determined that the two-bar edit process has been executed, and the process proceeds to step S616.

First, steps S604 to S6.
The case of proceeding to 06 will be described.

In step S606, it is determined whether or not there is performance data within the range of "0≤T <4". If the determination result of step S606 is negative, that is, if the performance data is within the range of "0≤T <4", the music data for which the one-bar edit process and the two-bar edit process have not been executed, or one bar After executing the edit process and the two-bar edit process, it is determined that the music data is the performance data added to the first measure, and the process proceeds to step S614, where error processing such as displaying an error message on the display unit 20 is performed. This reedit execution processing routine ends. That is, in this case, since the reedit SW is operated for the music data that cannot be reedited, error processing is performed and the reedit execution processing routine is ended.

On the other hand, if the result of the determination in step S606 is affirmative, that is, if there is no performance data within the range of "0≤T <4", it is determined that the music data can be reedited, and the process proceeds to step S608.

In step S608, the relative times t individually held by the set-up data within the range of "0 <T <4" are summed, and this value is stored as a variable X in the register set in the RAM 16. . That is, after executing the one-bar edit process, the setup data does not exist within the range of “0 <T <4”. However, after executing the one-bar edit process, the operator May write the set-up data in the first measure, and in that case, the set-up data exists within the range of “0 <T <4”. Step S6
When the process of 08 is completed, the process proceeds to step S610.

In step S610, the relative time t of the setup data within the range of "0 <T <4" is set to
Rewrite all as "0". That is, all set-up data existing within the range of “0 <T <4” is also rewritten to “relative time t = 0”. Step S610
When the process of (3) is completed, the process proceeds to step S612.

In step S612, the relative time t of the performance data located at the very beginning is rewritten to "t-4 + X", and the set-up data existing in the range of "0 <T <4" is changed to "t <4 <X". The influence on the performance data due to the rewriting to the relative time t = 0 ”is eliminated, and the reedit execution processing routine is ended.

Therefore, by the above processing, the music data whose performance data has been moved by the one-bar edit processing is
It will be restored to the original state before the move.

Next, steps S604 to S6.
The case of proceeding to 16 will be described.

In step S616, the relative times t individually held by the set-up data within the range of "0 <T <8" are summed, and this value is stored in the register set in the RAM 16 as the variable X. . That is, after the 2-bar edit process is executed, the set-up data does not exist within the range of “0 <T <8”, but after the 2-bar edit process is executed, the operator May write the set-up data in the first or second measure, and in that case, the set-up data exists within the range of “0 <T <8”.
When the process of step S616 ends, step S61
Go to 8.

In step S618, the relative time t of the setup data within the range of "0 <T <8" is set to
Rewrite all as "0". That is, all set-up data existing within the range of “0 <T <8” is also rewritten to “relative time t = 0”. Step S618
When the process of (3) is completed, the process proceeds to step S620.

In step S620, the relative time t of the performance data located at the very beginning is rewritten to "t-8 + X", and the set-up data existing in the range of "0 <T <8" is changed to "t <8 <X". The influence on the performance data due to the rewriting to the relative time t = 0 ”is eliminated, and the reedit execution processing routine is ended.

Therefore, by the above processing, the music data whose performance data has been moved by the two-bar edit processing is
It will be restored to the original state before the move.

Although not described in detail in the above embodiment, the automatic musical instrument has a default (default value), and the default and the setting state by the operating section 18 are set in a predetermined area of the RAM 16. It is stored in and can be read out at any time.

In the above embodiments, the case of the MIDI standard has been described, but the present invention is not limited to this, and the present invention can of course be applied to an automatic performance device that processes music data other than the MIDI standard. .

[0081]

Since the present invention is constructed as described above, it has the following effects.

In an automatic performance device having a storage means for storing music data and a reproducing means for reproducing the music data stored in the storage means, for sequentially reproducing the music data stored in the storage means by the reproducing means, Since the reproduction start of the predetermined data in the music data stored in the storage means is shifted for a predetermined time, when the reproduction start of the music data excluding the set-up data is shifted for a predetermined time, the sound source is set. -After processing the update data, the sound source can be made to generate the actual musical sound based on the music data excluding the set-up data.

Therefore, since the actual tone generation of the musical tone in the sound source is not affected by the processing time of the set-up data, it is possible to secure the tone generation of the musical tone with an accurate time length designated by the music data.

Therefore, according to the present invention, even when the music data in which a large amount of the setup data is arranged at the beginning of the first measure of the music is reproduced, the processing of the setup data in the sound source is performed. Therefore, it is possible to surely prevent the time length of sounding the musical sound designated by the performance data from being shortened.
