Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input information changing device for an electronic musical instrument, which changes the effectiveness of a key or the like based on input information input from a key of an electronic piano or the like.

[0002]

2. Description of the Related Art Conventionally, there are electronic pianos, electronic keyboards, and the like as electronic musical instruments for playing by changing a hit state. For example, in an electronic piano that plays by pressing a key on the keyboard, In response, a musical sound is generated and the performance is performed.

In this electronic piano, in order to detect the state of keystroke, a sensor is arranged below the key or the like, so-called information such as key moving speed information (initial) or key pressing force information (after). Touch information (touch data)
Is being detected. In addition, in the electronic piano, in order to change the pronunciation state according to the strength of keystrokes, all keys on the keyboard are adjusted collectively by key touch sensitivity (key touch effectiveness). ing. The effectiveness of the key touch defines, for example, the relationship between the initial size of the touch information indicating the key pressing speed and the size of the signal output to the sound source (that is, the sound output level). Therefore, for example, as shown in FIG. 8, by using an oblique line for changing data (touch curve), the touch data before conversion on the horizontal axis of the graph is changed to the touch data after conversion on the vertical axis. Based on the touch data, the sound output level is adjusted.

[0004]

However, if the so-called split mode is adopted, it may not always be possible to perform a sufficient performance by simply adjusting the effect of key touches in a batch. .

That is, conventionally, an electronic piano or the like has a function of a split mode in which the keyboard is divided into left and right regions corresponding to the right hand and the left hand, and input information by the keys belonging to each region is processed respectively. If you want to play with this split mode set,
For example, the bass is played in the left area and the melody is played in the right area.

However, especially for beginners, since the strength of the right hand and the strength of the left hand are different, there is a problem in that good performance is difficult if the entire keyboard is set to have the same key touch effect. In addition, even advanced players have the problem that it is not always easy to perform an excellent performance if the effect of key touch is the same.

The present invention has been made in order to solve the above-mentioned problems, and by adjusting the effect of key touch or the like, for example, even a beginner can perform a good performance, and an advanced player can play a more excellent performance. An object is to provide an input information changing device for an electronic musical instrument that can be performed.

The functions of 17c will be briefly described.

Of the three types of curves for setting the effectiveness of the key touch shown in FIG. 3, for example, FIG. 3 (B)
When the normal input is selected and there is a key input at a certain value (for example, 1/2 of the maximum value on the horizontal axis), a value proportional to the key input (for example, 1/2 of the maximum value on the vertical axis). ) Is pronounced. Further, when the light type shown in FIG. 3A is selected, even if a key input is made with the same value as that for the normal type, a sound is produced larger than the normal tone. That is, even if the key 3 is pressed weakly, a larger sound can be obtained than in the normal setting. On the other hand, when the heavy type shown in FIG. 3 (C) is selected, even if a key input is made with the same value as that for the normal type, a sound smaller than that for the normal type is produced. That is, even if the key 3 is strongly pressed, only a smaller sound can be obtained than in the normal setting.

That is, the light switches 15a and 17a, the normal switches 15b and 17b, and the heavy switch 15
By selecting and pressing c and 17c, it is possible to arbitrarily change the effect of the left and right key touches and play. Next, the electrical configuration of the electronic piano 1 will be described based on the block diagram of FIG.

As shown in FIG. 4, the main control portion of the electronic piano 1 includes a CPU 21 for performing an arithmetic operation, a ROM 22 for storing a control program and a map (or an arithmetic expression) corresponding to a touch curve, input information and the like. RAM2 for temporary storage
3, a sound source 24, a keyboard scan circuit 25 for detecting the states of the keys 3 of the keyboard 5, and a panel switch scan circuit 26 for detecting the states of the switches 11 to 17, which are connected via a bus 27. The keyboard 5 is connected to the keyboard scan circuit 25, and the switches 11 to 11 provided on the panel 7 are connected to the panel switch scan circuit 26.
17, a speaker 29 is connected to the sound source 24 via an amplifier 28.

Next, the operation of the touch information changing device for an electronic musical instrument of the present embodiment having the above-mentioned structure will be described with reference to the flow charts of FIGS. Here, FIG.
6 shows the overall processing of the present apparatus, FIG. 6 shows the switch processing performed according to the pressed switches 13 to 17, and FIG.
Indicates a key-on process performed according to the pressed key 3.

First, as shown in FIG. 5, the power switch 11
Is entered, the step (the step will be referred to as S below)
At 100, initial setting is performed. For example, the effect of touching all the keys 3 is set so as to be collectively determined by using the normal graph of FIG. Further, the split flag SPF is set to φ to indicate that the split mode is not set.

In subsequent S110, a switch process described later is performed, and in S120, a key-on process also described later is performed. Further, in subsequent S130, a key-off process indicating the end of the input with the key 3 is performed, and in S140, other processes such as an indicator not shown are performed, and the present process is temporarily terminated.

Next, in the switch processing shown in FIG. 6, first, in S200, it is determined whether or not there is an event input of the lower touch curve setting switch group 15, that is, the light switch 15a, the normal switch 15b, and the heavy switch 1.
It is determined whether any of 5c is pressed. If an affirmative judgment is made here, the routine proceeds to S210, while if a negative judgment is made, the routine proceeds to S220.

In S210, the map corresponding to the lower touch curve used to change the effectiveness of the key touch is changed according to the pressed lower touch curve setting switch group 15. That is, the light switch 15a, the normal switch 15b, or the heavy switch 15c is changed to one of the lower touch curves as shown in FIG.

On the other hand, in S220, similarly to S200, whether or not there is an event input of the upper touch curve setting switch group 17, that is, whether or not any of the light switch 17a, the normal switch 17b, and the heavy switch 17c is pressed. To determine. If an affirmative judgment is made here, the routine proceeds to S230, while if a negative judgment is made, the routine proceeds to S240.

In S230, the map corresponding to the upper touch curve used for changing the effectiveness of the key touch is changed according to the pressed upper touch curve setting switch group 17 in the same manner as in S210. In other words, the light switch 17a, the normal switch 17b, or the heavy switch 17c is changed to one of the upper touch curves as shown in FIG.

That is, in the processing of S200 to S230, in order to determine the appropriate effect of the key touch of the lower and upper keys, the touch curves are set individually according to the ON / OFF state of both switch groups 15 and 17. This is a process for doing. Then, in S240, it is determined whether or not there is an event input of the split mode setting switch 13. If an affirmative determination is made here, the process proceeds to S250, and if a negative determination is made, the process proceeds to S280.

In S250, the split mode flag S
It is determined whether the PF is 1, that is, whether the split mode is currently set. If an affirmative determination is made here, the process proceeds to S260, and if a negative determination is made, the process proceeds to S270. In S260, the split mode setting switch 1 is operated in the split mode in S240 and S250.
Since it is determined that 3 has been pressed, that is, it has been determined that the split mode has been canceled, the split mode flag SPF is set to φ and the process proceeds to S280.

On the other hand, in S270, the above S240 and S
In 250, it is determined that the split mode setting switch 13 has been pressed when not in the split mode, that is, it is determined that the split mode has been set. Therefore, the split mode flag SPF is set to 1 and the process proceeds to S280.

At S280, other switch processing and the like are performed, and this processing is once terminated. Next, in the key-on process shown in FIG. 7, first, in S300, it is determined whether or not there is a key-on. If an affirmative determination is made here, the process proceeds to S310.
On the other hand, if a negative decision is made, this processing is once terminated.

In S310, the split mode flag S
Whether the PF is 1 or not, that is, whether or not the split mode is currently set is determined. If an affirmative determination is made here, the process proceeds to S320, and if a negative determination is made, the process proceeds to S340. S320
Then, it is determined whether the key 3 is lower or upper based on the key number, that is, it is determined whether the pressed key 3 is on the left side (lower) or right side (upper) of the keyboard 5 and is on the lower side. If so, the process proceeds to S330, while if it is in the upper, the process proceeds to S340.

At S330, since the key number is lower, the touch data of the key 3 is changed based on the map of the touch curve of the lower set at S210 of FIG. On the other hand, in S340, since the key number is in the upper, the touch data of the key 3 is changed based on the map of the touch curve of the upper set in S230 of FIG. Even if it is determined in S310 that the current split mode is not set, this S3
40. At that time, regardless of the key number, a predetermined touch curve (in the present embodiment, S2 in FIG. 6 is used).
The touch data of the key 3 is changed based on the upper touch curve set at 30).

That is, in the processing of S300 to S340, it is determined whether the pressed key 3 is the lower or upper according to the key number, and the touch is performed based on the touch curve set corresponding to each area. This is a process for changing data. In the following S350, sound generation processing is performed based on the touch data changed in S330 or S340, and the present processing is terminated.

As described above, in this embodiment, by operating the lower and upper touch curve setting switch groups 15 and 17, the lower touch curve and the upper touch curve for setting the effectiveness of the key touch are set. , Each can be set to a desired curve. Therefore, when the key 3 is pressed, it is determined whether the key 3 is the lower or the upper, and based on the touch curves of the lower or the upper preset by the switches 15 and 17, The touch data input by the key 3 can be changed to appropriate touch data.

For example, when a beginner operates an electronic piano, the lower (left hand) side generally becomes weaker. Therefore, if the light switch 15a of the lower touch curve setting switch group 15 is pushed in advance and the lower side is weakly pressed, a loud sound is produced. On the other hand, if the heavy switch 17c of the upper touch curve setting switch group 17 is pressed and the upper side is strongly pressed, a small sound is produced, so that a good balance between the left and right can be performed. .

When playing the accompaniment on the lower side and playing the melody on the upper side, the normal switch 15b of the lower touch curve setting switch group 15 is pushed in advance, while the light switch 17a of the upper touch curve setting switch group 17 is pressed. If you keep pressing, you can perform a stable accompaniment and perform an excellent performance with clear strength.

In other words, in the present invention, the touch curves of the lower and upper can be set to desired curves, so that there is a remarkable advantage that even beginners and advanced players can easily perform excellent performances. It should be noted that the present invention is not limited to the above-mentioned embodiments and can be of course implemented in various modes within the scope of the gist of the present invention.

[0037]

As described in detail above, in the input information changing apparatus for an electronic musical instrument of the present invention, the effect of the input means corresponding to each area divided by the input separating means is individually changed by the individual input information changing means. Therefore, even a beginner, for example, can perform a sufficiently excellent performance. In addition, since the effect of the input means in each area can be easily and arbitrarily changed, a variety of excellent performances can be easily realized regardless of whether the player is a beginner or an advanced player.
