Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data setting device used for setting various data such as tempo data used for automatic performance, and an automatic performance device having the same.

[0002]

2. Description of the Related Art Conventionally, an electronic musical instrument having an automatic performance function is provided with a tempo up switch and a tempo down switch for changing the setting of tempo data that determines the tempo of the automatic performance. When the tempo up switch is operated with one touch, the tempo data is incremented for each operation, and when the tempo down switch is operated with one touch, the tempo data is decremented for each operation. In addition, if you keep pressing the tempo up switch, the tempo data will be continuously incremented at a fixed timing from the time when a predetermined time has elapsed, and if you continue to press the tempo down switch, the tempo data will change from the time when the predetermined time has passed to a constant timing. The tempo data is continuously decremented by.

[0003]

However, in such a conventional tempo setting function, the time until the tempo data starts changing and the timing of changing the tempo data are always constant when each switch is held down. It is constant.
Therefore, if you want to change the tempo data quickly,
Dissatisfaction occurs when the time until the tempo data changes and the timing of the change are slow. In addition, when it is desired to set the tempo data accurately, the timing of changing the tempo data may be unacceptable because the timing at which the switch operation is stopped is shifted when the desired tempo data is reached. Therefore, it is not possible to change the setting of the tempo data that suits the user's sense and speeding desire.

The present invention has been made in view of such conventional problems, and has a data setting device and a data setting device capable of changing data in a changing manner that suits the user's sense and speeding desire. It is an object of the present invention to provide an automatic performance device.

[0005]

In order to solve the above problems, according to the present invention, storage means for storing data, detection means for detecting a touch response to an operator,
First conversion means for converting the touch response into the amount of change in the data, second conversion means for converting the touch response into a waiting time until the change of the data is started, and the touch response with the data And a rewriting unit that rewrites the data stored in the storage unit according to the change amount, the waiting time, and the change time interval converted by each of the conversion units. The main point is to have.

[0006]

In the above structure, when the operator is touched, the touch response is detected by the detecting means. Then, the first conversion unit converts the touch response into a data change amount, and the second conversion unit converts the touch response into a waiting time until the data change is started.
The conversion means converts the touch response into a data change time interval. Then, when the touch response is converted into the change amount, the waiting time, and the change time interval by each conversion unit in this way, the rewriting unit rewrites the data stored in the storage unit according to these. Therefore, the data stored in the storage unit is changed in a different manner according to the strength and speed of the touch on the operator by the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of the automatic musical instrument according to this embodiment. In this block diagram, operation information from the control sw group 2 is input to the CPU 1 via the touch detection unit 3. The CPU 1 uses the operation information, the programs stored in the ROM 4, and the R
The display unit 6 and the sound source 17 are controlled based on the data stored in the AM 5. As the control sw group 2, FIG.
As shown in, a pair of tempo sw7, st / sp (start / stop) sw8, and five rhythm select s
w9 is provided, tempo sw7 is up sw7a
And down sw7b. Further, as the display unit 6, the LCD 10 indicating the value of tempo data is displayed.
Is provided.

The up sw7a and the down sw7b
As shown in FIG. 3, has a dome portion 11 made of rubber and having flexibility, and an operation portion 12 is formed on an upper portion of the dome portion 11. An annular first contact 13 is provided on the peripheral portion of the lower surface of the operation portion 12, and a second portion having a shorter protruding length downward than the first contact 13 is provided in the central portion.
Contact points 14 are provided so as to project. Also, the first contact 13 and the second
Lower contacts 15 and 16 are formed on the lower surface facing the contacts 14. Therefore, when the dome portion 11 is deformed by pressing the operation portion 12, the first contact 13 and the second contact 13
The contact point 14 comes into contact with the lower contact points 15 and 16 to be turned on with a time difference according to the strength of the touch on the operation unit 12, and the touch strength is increased by the ON time difference between the first contact point 13 and the second contact point 14. To be detected.

Further, the ROM 4 is provided with a conversion table shown below and shown in FIGS. Conversion table A (FIG. 4): the ON time difference T between the first contact 13 and the second contact 14 corresponds to the touch strength P of 0 to 10 that becomes larger as the ON time difference T becomes smaller. And remembered. Conversion table B (FIG. 5): touch strength P and increases as the touch strength P increases 1, 3,
The tempo change amount ΔT having four stages of 7 and 10 is stored correspondingly. Conversion table C (FIG. 6): touch strength P and decreases as the touch strength P increases, 1, 3,
Auto-increment wait time x consisting of 10 stages x
And are stored correspondingly. Conversion table D (FIG. 7): touch strength P and decreases as the touch strength P increases, 1, 3,
Auto increment change time ΔT consisting of 3 steps
i and i are stored correspondingly.

It should be noted that the ROM 4 together with these conversion tables and programs, the five rhythm select sw.
Five types of rhythm patterns corresponding to 9 are stored. Each rhythm pattern consists of data in which rhythm sounds such as rock and waltz that compose the rhythm are stored in the order of addresses. Then, when the automatic rhythm performance is started, the CPU 1 reads out the constituent data of the rhythm pattern selected in advance in the order of addresses, and sequentially instructs the sound source 17 to generate sound based on this data. Sound source 17 is CP
A musical tone waveform is generated according to an instruction from U1, and a rhythm sound is generated by operating the sound system 18 including an amplifier, a speaker, and the like by this musical tone waveform.

Next, the operation of this embodiment having the above configuration will be described according to the flow shown in FIG. That is,
When a power source (not shown) is turned on, the CPU 1 starts its operation according to the main flow shown in FIG. 8, and first executes an initialization process (SA1). In this initialization process, initial values are set in various registers used in the subsequent flow. Subsequently, sw processing (SA2), display processing (SA3), rhythm sound generation processing (SA4), and other processing (S) other than those executed in SA2 to SA4.
A5) is sequentially executed, and while the power is on, SA2
~ SA5 loop is repeated.

The sw processing (SA2) is performed according to the flow shown in FIG. 9, and the up sw processing (SB1), do
The wn sw process (SB2), the rhythm select sw process (SB3), and the st / sp sw process (SB4) are sequentially executed.

The up sw process (SB1) is shown in FIG.
And a series of flows shown in FIG. 11, the following flags and timers are used in this flow.

UpF: up sw flag IncF: Increment interval time count flag TstF: Increment start wait time count stop flag t: Increment start wait time timer t ₁ : Increment interval time count timer That is, whether the up sw7a is on first determine whether (SC1), if the Stay up-SW7a is turned off, the flag UPF, IncF, clears TstF, and a timer t, and t ₁ (SC2). Also, up s
When w7a is in the ON state, it is determined whether or not upF is in the set state (SC3). This upF is a flag set in SC9 described later, and is up s
Immediately after w7a is turned on, it is reset by the above-mentioned processing of SC2. Therefore, in this case, the ON time difference between the first contact 13 and the second contact 14 is set in the predetermined register T (SC4).

Next, based on the contents of the register T, the contents of the conversion table A are read out and stored in the register P (SC5).
A value indicating the strength of touch corresponding to the ON time difference between the first contact 13 and the second contact 14 is stored. Subsequently, the contents of the conversion tables B to D are read based on the contents of the register P and stored in the registers ΔT, x, ΔTi (SC6). Therefore, by this processing of SC6, ΔT
Stores the tempo change amount corresponding to the touch strength, x stores the auto increment wait time corresponding to the touch strength, and ΔTi stores the auto increment change time corresponding to the touch strength.

Further, the value of ΔT is added to the register Tn which stores the value of the current tempo to update it (SC
7) After resetting t (SC8), upF indicating that the above processing has been performed is set (SC9). Next, it is determined whether or not t = x (auto increment waiting time) (SC10 in FIG. 11). If t ≠ x, the flow is passed, and when t = x, TstF is set (S).
C11).

Next, it is determined whether or not IncF is in the set state (SC12). This IncF is a flag set in SC15 described later, and up sw7 is used.
Immediately after a is turned on, it is reset by the above-mentioned processing of SC2. Therefore, after adding the value of ΔT to the register Tn which stores the current tempo value, updating this (SC13), and resetting t ₁ (SC1
4), IncF indicating that this SC14 processing has been performed
Is set (SC15). Furthermore, t ₁ = ΔTi
It is determined whether or not (auto increment change time) (SC16), and if t ₁ ≠ ΔTi, this flow is exited, and the current tempo value is stored when t ₁ = ΔTi. After adding the value of ΔT to the register Tn and updating it (SC17), t ₁ is reset (SC1
8).

If the up sw7a is in the ON state, when this flow is executed again, SC1 to SC3
However, since upF = 1 already,
The processing of SC4 to SC9 is not performed, and SC3 → SC10 →
Go to SC11 → SC12. However, already IncF = 1
Since it is in the state of, the processing of SC13 to SC15 is not performed. Therefore, when the up sw7a is in the ON state, substantially only the determination process of SC16 to SC18 is performed, and ΔT is added to the register Tn storing the current tempo value each time t ₁ = ΔTi. Will be updated.

On the other hand, the timer interrupt 1 shown in FIG.
Is executed at fixed time intervals, and if downF or the upF described later is in the set state (SD1 is YES) and TstF is in the reset state (SD2 is YES), t is incremented (SD3). . When t = x is determined in SC10 of FIG. 11, since the auto-increment waiting time is stored in x, SC11 or less is kept until t = x and the auto-increment waiting time elapses. Will not be executed. Since this auto-increment waiting time is a value according to the strength of the user's touch on the up sw7a, the user can freely set the auto-increment waiting time by touching the up sw7a with an arbitrary strength. can do.

Further, the timer interrupt 1 shown in FIG.
In, when DecF or the IncF described later is in the set state (SD4 is YES), t ₁ is incremented. Then, at SC16 of FIG. 11, t ₁
= When it is determined the .DELTA.Ti, since the auto-increment change time is stored in the .DELTA.Ti, until becomes t ₁ = .DELTA.Ti elapses the autoincrement change time, so that the SC17 following process is not executed .
Also, since this auto increment change time also has a value according to the strength of the touch on the up sw7a by the user, the user can freely set the auto increment change time by touching the up sw7a with an arbitrary strength. can do. Then, when this auto increment change time has elapsed (SC16 is set to Y
ES), since the register Tn that stores the current tempo value is updated, the update speed = change speed of the tempo value changes according to the strength of the touch on the up sw7a by the user.

Moreover, the value ΔT added to the register Tn in SC17 is the value stored in the register ΔT in SC6, and this ΔT is also up sw7 of the user.
It is a value according to the strength of the touch on a. Therefore, the tempo data stored in the register Tn has a shorter waiting time and a shorter time interval as the touch on the up sw7a is stronger by executing the above-described flows shown in FIGS. 10 and 11, and , Increase with a large amount of change. Further, while the up sw7a is in the ON state, the tempo data value increases with the change amount at the time interval. And up sw7
When this is turned off by stopping the operation of a, the process proceeds from SC1 to SC2 as described above, and each flag upF,
After clearing IncF, TstF, and timers t and t ₁ , this flow is exited.

The down sw process (SB2 in FIG. 9)
Is performed according to the series of flows shown in FIGS. 13 and 14, but this flow differs from the above-described flows shown in FIGS. 10 and 11 only in the following points. That is, upF: up used in the above-mentioned up sw process.
Instead of the sw flag, a downF: down sw flag is used, and instead of the IncF: increment interval time count flag, a DecF: decrement interval time count flag is used. In addition, S of the above-mentioned up sw processing
In C7, SC13, and SC17, the value of ΔT is added to the register Tn which stores the value of the current tempo to update it, while the corresponding S of the down sw process is updated.
At E7, SE13, and SE17, the value of ΔT is subtracted from the register Tn that stores the current tempo value to update it.

Therefore, when the series of flows shown in FIGS. 13 and 14 are executed, the tempo data stored in the register Tn indicates that the stronger the touch on the down sw7b, the shorter the waiting time and the shorter time interval. ,
And it decreases with a large amount of change. Also, down
While sw7b is in the ON state, the tempo data value decreases with the change amount at the time interval, and d
When this is turned off by stopping the operation of own sw7b, this flow is exited.

Further, the rhythm select sw process (see FIG. 9)
SB3) is performed according to the flow shown in FIG. 15, and it is first determined whether or not there is a change in the state of the rhythm select sw9 (SF1). When any of the five rhythm select sw9 is operated and its state is changed, the rhythm number corresponding to the operated sw is stored in the register RR (SF2), and then the address is stored. The register AD is reset (SF3).

The st / sp sw processing (SB in FIG. 9)
4) is performed according to the flow shown in FIG. 16, and st / s
It is determined whether there is a change in the state of psw8 (SG
1). When the st / sp sw8 is operated and its state is changed, the start flag STF is inverted (SG2), and therefore the start flag STF is set to st.
Each time / sp sw8 is operated, it changes to 1,0.
After that, the address register AD is reset (SF
3) Exit this flow.

On the other hand, in the main flow shown in FIG. 8, the display process of SA3 subsequent to the sw process of SA2 is as shown in FIG.
This is performed according to the flow shown in FIG. 7, and the contents of the register Tn are displayed (SH1). Therefore, by the processing of this SH1, SC7, SC13 and SC1 in FIGS.
7, and SE7, SE13 and SE17 of FIGS.
The value of the register Tn updated by is displayed on the display unit 6 sequentially. Therefore, the value of the tempo data displayed on the display unit 6 also changes with the waiting time, the time interval, and the change amount according to the strength of the touch on the up sw7a and the down sw7b.

Further, in the main flow shown in FIG. 8, the rhythm sounding process of SA4 following the display process of SA3 is performed according to the flow shown in FIG. That is, first, it is determined whether or not the start flag STF is in the set state (SJ1), and if it is in the reset state, the address register AD is cleared and the register Tx is cleared.
The predetermined value is stored in (SJ2). If the start flag STF is set, the address register A
RR content (rhythm number) with D content as address
The rhythm pattern corresponding to is read from the ROM 4 (S
J3), and sends this to the sound source 17 (SJ4). Therefore, according to the transmitted rhythm pattern, the sound source 17
Sound system 1 by generating a musical tone waveform
Rhythm sound starts to be generated from 8.

Next, the register T in which the predetermined value is stored
It is determined whether or not the value of x is 0 or less, and when Tx ≦ 0, the address register AD is incremented. Further, it is determined whether or not AD = END (SJ5), that is, whether or not the reading up to the final data of the rhythm pattern has been completed. If AD ≠ END, then T
After storing a predetermined value in x (SJ9), the determination process from SJ3 is repeated. Further, when AD = END, the reading up to the final data of the rhythm pattern is completed, and when one rhythm pattern performance is completed by this, AD is reset (SJ8) and the processing of SJ9 described above is executed. After that, the determination process from SJ3 is repeated.

Therefore, by repeating the loop of SJ3 to SJ9, the sound system 18 sequentially generates the musical tones constituting the rhythm pattern, and the rhythm pattern is repeatedly automatically played. At this time, in the timer interrupt 2 of FIG. 19 executed at regular time intervals, when the start flag STF is in the set state (SI1 is YES), the value of the register Tn is subtracted from the current value of the register Tx, I am updating this. Here, since a predetermined value is stored in Tx as an initial value as described above, Tx decreases rapidly when the value of Tn is large and decreases slowly when the value of Tn is small. Therefore, every time Tx becomes "0" in SJ5 of FIG. 18, the address register AD is generated in the next SJ6.
By incrementing, the reading speed of the rhythm pattern becomes faster as the value of the tempo data stored in the register Tn becomes larger, and becomes slower as the value of the tempo data becomes smaller. Therefore, the rhythm composed of musical tones generated by the sound system 18 also increases or decreases the tempo depending on the value of the tempo data.

[0030]

As described above, according to the present invention, the amount of change in rewriting data, the waiting time until rewriting, and the change time interval in rewriting are changed according to the touch response to the operator. . Therefore,
Depending on the touch response to the operator, all the temporal elements related to rewriting the data will change, which makes it possible to change the setting of the data in a changing manner that suits the user's sense and speed desire. Become.
