Description

Electronic piano aerial shooting auxiliary device

The present invention relates to an auxiliary device, in particular to an electronic piano aerial recording and inserting auxiliary device capable of automatically switching tone colors by a pedal device.

Electronic keyboards often play an important role in music performance, and many electronic pianos have built-in automatic accompaniment rhythms and the sounds of various instruments (such as piano, guitar, violin, organ, brass, etc.) for users to choose, and It helps users to interpret the music more richly.

In the process of playing music with an electronic keyboard, in most cases, the user will use the right hand to play the main melody of the music, and use the left hand to play a chord or accompaniment that matches the main melody. Further, in order to increase the integrity and richness of the music, an accompaniment melody (which is played with the right hand and different from the main melody) is added to the empty shot of the main melody (that is, where the gap between the two phrases in the main melody is large) (Also known as "empty shot insertion") is an indispensable arrangement method, especially in the type of song.

However, if you encounter a song with a faster rhythm or a higher overall complexity, It is very difficult for layer keyboard users to take into account both hand playing and fast and frequent switching of tone. Therefore, how to make the user in the actual live performance can reach the place where the main melody needs to be inserted in the air, The keyboard quickly and automatically switches to a different instrumental tone than the main melody to play the "empty shot insert" part for the user, which has become the subject of this case.

Usually where the main melody is empty, the ending of the phrase is long. The player's left hand is responsible for the manipulation of chords and accompaniment. Therefore, the main melody and insert play are usually performed by the right hand. In order to free up the right hand to play the insert, the end of the phrase must be maintained by the sustain pedal, and it can continue to sound after the finger leaves the key (otherwise, the end of the main melody phrase will break when the right hand plays the insert. Drop). The new model is to allow the keyboard player to perform a single action of pedaling, without having to manipulate the keyboard keys of the keyboard, so that the keyboard can perform the sustaining and the automatic switching of the tone color together.

Therefore, it is an object of the present invention to provide an electronic keyboard aerial shot insertion assisting device capable of automatically switching the tone of the main melody playing area by stepping on the pedal device.

The new electronic keyboard aerial shot auxiliary device is suitable for being electrically connected with a pedal device and an electronic piano. The electronic keyboard has a main melody playing area for being played to output a main melody. The electronic keyboard aerial shot auxiliary device includes an input. Unit, one electrical connection A processing unit of an input unit, and an output unit electrically connected to the processing unit. When the input unit receives an operation signal, the processing unit generates a sustain signal and a tone switching instruction according to the operation signal, and outputs the sustain signal and the tone switching instruction to the keyboard through the output unit, so that the keyboard According to the sustain signal, the main melody is continuously sounded, and according to the tone switching instruction, the output tone of the main melody playing area is changed.

In some embodiments, the time point when the processing unit outputs the tone switching instruction is after the time point when the sustain signal is output. This sequence is to ensure that the sound of the note to be sustained is maintained before changing the tone of the main melody playing area. In addition, the tone switching instruction can have several different formats, so that the main melody and the insertion can be changed back and forth between two instrument sounds or multiple instrument sounds can be changed in a specified order.

In an embodiment, the electronic keyboard aerial shot auxiliary device is also suitable for electrically connecting a pedal device, and the pedal device is triggered to generate the operation signal.

In one embodiment, the electronic keyboard aerial shooting auxiliary device is integrated in the electronic keyboard.

Referring to FIG. 1, an embodiment of the novel electronic keyboard aerial shooting auxiliary device 1 is adapted to be electrically connected to the pedal device 2 and the electronic keyboard 3. Among them, the electronic keyboard aerial recording and insertion auxiliary device 1 includes an input unit 11, an output unit 12, and a processing unit 13 electrically connected between the input unit 11 and the output unit 12.

The pedal device 2 may be, for example, a sustain pedal or a switch pedal dedicated to an electronic keyboard. The pedal device 2 has a switch (not shown) which can be touched by a pedal, whereby the pedal device 2 can output a corresponding operation signal Si (shown in the figure) according to the state in which the pedal is depressed or released. 2). The operation signal Si in this embodiment is, for example, a high-level DC voltage signal, and when the pedal is continuously depressed or triggered (for example, when the user presses and holds it), the pedal device 2 will The operation signal Si is continuously output, and when the pedaling operation to which the pedal is subjected is ended (the user releases the pedal), the pedal device 2 ends outputting the operation signal Si, that is, the operation signal Si is continuously output for the same length of time The length of time that the pedal is continuously pressed or triggered.

The electronic keyboard 3 includes a key unit 31, a control panel 32 for switching tone colors and function settings, and an input interface electrically connected to the electronic keyboard aerial shooting auxiliary device 1 Unit 33, where the number of keys of the key unit 31 may be 61 or 76 keys, but not limited thereto. The input interface unit 33 of this embodiment includes two input interfaces (usually higher-level electronic pianos have more than two pedal input interfaces, details of which will be described later). The functions of sustain and tone switching can be set to these two respectively. Each input interface is controlled by a pedal. In this embodiment, the input interface unit 33 is an output unit 12 that is electrically connected to the electronic keyboard aerial shot auxiliary device 1, so the sustain and tone switching functions of the electronic keyboard 3 are controlled by the electronic keyboard aerial shot auxiliary device 1. It is specifically noted that the electronic keyboard aerial shot inserting auxiliary device 1 can also be integrated into the pedal device 2. Therefore, in this embodiment, the sustain and tone switching functions of the electronic keyboard 3 can be directly controlled by the pedal device 2.

The keyboard 3 can control the sustain function through the pedal device 2. That is, when the pedal device 2 is triggered (such as pedaling), the pedal device 2 will drive the keyboard's aerial shot insertion assist device 1 to generate a sound for the main melody to continuously sound. The sustain signal is such that when the keyboard 3 receives the sustain signal, the currently played melody sound will continue to sound after the finger is off the key, and the melody sound output will not be ended until the sustain signal ends. In particular, the sustain referred to in this specification refers to the sostenuto function of the electronic keyboard, which is called selective sustain, selected sustain, specific sustain, partial sustain, or sustain in Chinese in Chinese.

Specifically, for example, if the sustain function is not enabled, when the user presses the key unit 31 (for example, the center C key) of the keyboard 3, the keyboard 3 will output a "DO" sound corresponding to the center C key. If the user keeps holding down the center C key, the keyboard 3 will continue to output the "DO" sound corresponding to the center C key, but once the When the user releases the center C key, the electronic keyboard 3 immediately stops outputting a "DO" sound corresponding to the center C key. However, if the keyboard C key is pressed and the sustain function is activated by the pedal device 2 when the center C key is pressed, the "DO" sound of the center C key will continue to sound after the key is released, until It stops sounding after the sustain signal ends.

In addition, the key unit 31 of the electronic keyboard 3 can be divided into one or more playing areas. In this embodiment, it is divided into a main melody playing area (also called a right-hand playing area) and a chord accompaniment playing area (also called a left-hand playing area). ), The main melody playing area has more than two parts (commonly called Right 1 / Right 2 / Right 3 or Upper 1 / Upper 2 / Upper 3), and through the setting and operation of the control panel 32, each The parts can be set to different instrument sounds. For example, one part is a cello tone, and the other part is a guzheng tone. In addition, each part can be turned on or off separately, or they can be on the same Use all or only some of the parts at the same time. A part is like a musician in an orchestra. When a certain part is selected to use a certain tone, it is like asking the musician to play a certain instrument.

For the convenience of explanation, it is assumed that the main melody playing area of the electronic keyboard 3 has three parts, and the three parts are set to different instrument sounds, for example, the first part is set to a violin tone, and the second part is set to For guitar sound, set the third part to piano sound, but it is not limited to this. When the keyboard empty shot insertion assisting device 1 receives the operation signal of the pedal device 2, in addition to generating a sustain message for continuously sounding the main melody In addition to the signal, a tone switching signal is also generated. The electronic keyboard 3 can sequentially turn on one of the three voices by using the tone switching signal. For example, the user starts playing the violin tone of the first voice. When the keyboard 3 receives the tone switching signal, it will turn off the first part and enable the second part guitar tone. When it receives the tone switching signal again, it will turn off the second part and enable the third part piano tone. If the tone switching signal is received again, the third part will be turned off and the first part violin tone will be activated.

In this embodiment, the input unit 11 is adapted to be electrically connected to the pedal device 2 to receive an operation signal Si generated from the pedal device 2. The input unit 11 may include, for example, a signal input port and an electrical connection to the signal. The driving circuit between the input port and the processing unit 13 is not limited thereto.

The output unit 12 includes a first output port 121 electrically connected to the processing unit 13 and a second output port 122 electrically connected to the processing unit 13. The input interface unit 33 of the keyboard 3 includes a sustain pedal input connector. Hole and a switch pedal input connection (not shown), the first output port 121 is suitable for the sustain pedal input connection of the electronic keyboard 3, and the second output port 122 is suitable for the switch pedal input connection of the electronic keyboard 3 Holes, but not limited to this. It is added that each of the signal input port, the first output port 121, and the second output port 122 of the input unit 11 may be implemented as a connection terminal of an existing specification, and the foregoing specification may be, for example, Phone Jack, RCA, LAN, USB or MIDI, but not limited to this.

The processing unit 13 may be a processing circuit in this embodiment, and may be analogized. A circuit, a digital circuit, an analog digital hybrid circuit, or a single-chip microprocessor is implemented, which may include a delayed pulse generator and a frequency divider, but is not limited thereto. The processing unit 13 generates a sustain signal for continuously sounding the main melody and a tone switching instruction for switching the tone of the main melody playing area according to the operation signal. The sustain signal is used for the electronic piano 3 to continuously sound the long note of the main melody. , With the right hand free to play the empty shot insert, and the tone switching instruction is used to make the keyboard 3 switch the part of the main melody playing area so that it outputs an instrument sound different from the original main melody for the empty shot insert play. Detailed description will be described later.

In addition, it is to be noted that the electronic keyboard aerial shooting auxiliary device 1 is implemented in this embodiment as an independent device from the pedal device 2 and the electronic keyboard 3, so that it can be manufactured separately from the pedal device 2 and the electronic keyboard 3 and For sale, the electronic piano aerial shooting and inserting auxiliary device 1 may also be integrated into the pedal device 2 or integrated into the electronic keyboard 3 as described above, which is not limited to this embodiment.

In this embodiment, whenever the electronic keyboard aerial shot assisting device 1 receives the operation signal Si from the pedal device 2 once, the electronic keyboard aerial shot assisting device 1 will implement a method for generating a tone switching signal once. The switching signal generating method is based on receiving the operation signal Si of the electronic keyboard inserting auxiliary device 1 to cause the electronic keyboard inserting auxiliary device 1 to generate a sustain signal for continuously sounding the main melody and a signal for Tone switching instruction for switching the tone of the main melody playing area, so that the keyboard 3 can continuously sound the long note of the main melody according to the sustain signal, and according to the tone Switch the command to change the output tone of the main melody playing area. For details, please refer to the latter paragraph. By analogy, if the user depresses the pedal device 2 or 30 times in total, the electronic keyboard empty shot insertion assisting device 1 will correspondingly implement the tone color switching signal generating method 30 times.

Referring to FIG. 1 to FIG. 3 at the same time, the following will exemplarily explain in detail how the electronic keyboard aerial shot insertion auxiliary device 1 of this embodiment implements a single-time tone color switching signal generating method.

First, in step S1, when the processing unit 13 of the electronic keyboard shot assisting device 1 receives the operation signal Si from the pedal device 2 via the input unit 11, the processing unit 13 generates a sustain sound for continuously sounding the main melody. The signal Sa and a tone switching instruction Sb for switching the tone of the main melody playing area. It should be particularly noted that the sustain signal Sa and the tone switching instruction Sb are actually transmitted to the input interface unit 33 of the electronic keyboard 3 in the form of a switch contact, and depending on the requirements of the pedal polarity of the electronic keyboard 3, such as a high state signal It can indicate that the switch is open, and a low state signal indicates that the switch is off; or, a reverse state of the polarity of the pedal to a high state signal indicates that the switch is off, and a low state signal indicates that the switch is open.

In this embodiment, the sustain signal Sa is, for example, another high-state DC voltage signal similar to (or the same as) the operation signal Si. In addition, under the premise of ignoring the signal transmission delay, the start time point and the end time point of the sustain signal Sa and the operation signal Si are synchronized with each other. And the sustain signal Sa is used for the electronic keyboard 3 to receive In the sustain signal Sa, the currently played melody sound continues to sound after the finger is off the key, and the melody sound output is not ended until the end of the sustain signal Sa.

In addition, the tone switching instruction Sb is used to cause the keyboard 3 to switch the main melody playing area from the currently located part to the other of the three parts when receiving the tone switching instruction Sb. In other words, the tone color switching instruction Sb is a musical instrument tone for causing the electronic keyboard 3 to switch the main melody playing area.

In this embodiment, each tone switching instruction Sb generated by the processing unit 13 has one or more pulse waves p (shown in FIG. 2), and each pulse wave p is used for the electronic keyboard 3 to receive In pulse wave p, the main melody playing area is switched from the current part (instrument tone) to the next part (instrument tone) in a specific order according to the pulse wave number. It is added that the pulse width of each pulse wave p in this embodiment may be, for example, 20 milliseconds, but it is not limited thereto.

It is worth noting that, in this embodiment, when the processing unit 13 receives the operation signal Si for an odd number of times (such as the operation signal Si ′ shown in FIG. 2), the tone switching instruction Sb generated by the processing unit 13 will It is a first tone color switching instruction Sb ′ having one pulse wave p. On the other hand, when the processing unit 13 receives the operation signal Si for the even number of times (such as the operation signal Si "shown in FIG. 2), the tone switching instruction Sb generated by the processing unit 13 will be one with two The purpose of the second tone color switching instruction Sb "of the pulse wave p is to switch back and forth (skip the third part) using only a specific two of the three parts. For example, play the lead with the first part's violin sound, Two-part guitar sounds.

After the processing unit 13 generates the sustain signal Sa and the tone color switching instruction Sb, it proceeds to step S2.

In step S2, the processing unit 13 outputs the sustain signal Sa and the tone switching instruction Sb to the keyboard 3 via the output unit 12. More specifically, the processing unit 13 sends the sustain signal Sa through the first output port 121. The sustain pedal input socket output to the electronic keyboard 3 is outputted to the switch pedal input socket of the electronic keyboard 3 via the second output port 122. It is worth noting that, in each method for generating a tone color switching signal in this embodiment, the time point at which the processing unit 13 outputs the tone color switching instruction Sb is after the time point at which the sustain signal Sa is output. More specifically, the processing unit 13 first outputs the sustain signal Sa, and then outputs the tone switching instruction Sb when a predetermined delay time length is reached. The predetermined delay time length is counted from when the sustain signal Sa is output, and may be implemented as, for example, 20 milliseconds, but is not limited thereto. Therefore, there is a predetermined delay time difference td as shown in FIG. 2 between the starting point of each sustain signal Sa and the starting point of the corresponding tone color switching instruction Sb. This sequence is to ensure that the keyboard 3 maintains the note sound of the main melody, and then changes the tone of the playing area to play the insert, so that the last tone of the phrase (usually a long beat) is suddenly output with a different tone, And destroy the overall sense of the music.

The above is the description of the method for generating a single tone color switching signal performed by the electronic keyboard aerial shot insertion system device 1.

In order to facilitate the explanation of the convenience brought by the tone switching signal generation method for the user to play the electronic piano 3, here, as an example, suppose that the main melody playing area of the electronic piano 3 is to open the first part (the violin tone ).

When the user depresses the pedal device 2 for the first time while playing the electronic keyboard 3, the electronic keyboard empty shot insertion assisting device 1 executes the first tone color switching signal generating method, and generates the first tone switching signal in step S1. The tone switching instruction Sb ′ is output to the electronic keyboard 3 in step S2. The first tone switching instruction Sb 'in this embodiment enables the electronic keyboard 3 to switch the main melody playing area from the first part (violin tone) to the second part (guitar tone).

Next, when the user depresses the pedal device 2 for the second time, the electronic keyboard empty shot insertion assisting device 1 will execute the second method for generating the tone switching signal, and will generate a second tone switching instruction Sb in step S1 ", In step S2, the second tone switching instruction Sb "is output to the electronic keyboard 3. In this embodiment, the second tone switching instruction Sb ”enables the electronic keyboard 3 to switch the main melody playing area from the second part (guitar tone) twice in a specific order to jump back to the first part (violin tone). , That is, the third part (instrument sound) is skipped.

And when the user depresses the pedal device 2 for the third time, the electronic keyboard empty shot insertion assisting device 1 executes the third method of tone switching signal generation, which will cause the keyboard 3 to change the main melody playing area from the first part (the violin tone). ) To switch to the second part (guitar tone).

Then, when the user depresses the pedal device 2 for the fourth time, The tone assisting device 1 executes the fourth tone color switching signal generation method, so that the electronic keyboard 3 jumps the main melody playing area from the second part (guitar tone) back to the first part (violin tone) again.

Therefore, by performing the tone switching signal generation method of the keyboard empty shot insertion auxiliary device 1 multiple times (that is, the pedal device 2 is stepped on multiple times), the electronic keyboard 3 can cause the main melody to be played in three parts. Switch between the color of the first and second parts.

As mentioned above, for the user, as long as the instrument sounds corresponding to each part are set through the keyboard 3 control panel 32 in advance, the user can play the main melody of the music with the first part (violin tone), and then, When the airtime of the main melody is reached, the user can cause the keyboard 3 to perform the main melody sustain and switch the main melody playing area to the second part (guitar tone) to play the plug-in part as long as the user presses the pedal. Then, at the end of the "empty shot inserting" section, the user only needs to press the pedal again to enable the keyboard 3 to switch the main melody playing area back to the first part (violin tone) to continue playing the main melody of the music .

That is to say, with the method for generating a tone switching signal in this embodiment, the user can simultaneously perform the sustain and automatically switch the tone of the electronic keyboard 3 by a single action of "pedaling the pedal", and thus can reach the space of the main tune Switch tones more smoothly while shooting and play the "empty shot insert" section.

It is added that the application of this embodiment is to make the electronic keyboard 3 The melody playing area is switched back and forth between the first and second parts of the three parts. However, if the user wishes to cycle from the first to the third parts, then only the One tone color switching instruction Sb can be achieved with only a single pulse wave p. In addition, the electronic keyboard aerial shooting auxiliary device 1 may further include, for example, a mode selection switch (not shown) electrically connected to the processing unit 13 for switching the output format of the tone switching instruction Sb generated by the processing unit 13, that is, changing The number of pulse waves p and the output order of the tone color switching instructions Sb are not limited thereto. Through the mode selection switch, the user can select a number of preset tone switching modes. For example, the user can choose a more complicated tone switching mode, which is fixed to play the main melody with the first part of the three parts, and the inserted part The second and third parts are alternated, and the performance is like having two musicians alternately helping the lead player to accompany the insert part.

In addition, in other embodiments, the control panel 32 of the keyboard 3 may have a plurality of (usually four) panel setting memory (One Touch memory) buttons, and the user may set each panel setting memory button to select a different instrument tone Moreover, the plurality of panel setting memory buttons can be controlled by a switch pedal to enable one of them to be sequentially turned on. The tone switching instruction Sb is used to cause the keyboard 3 to switch from one of the panel setting memory buttons to the other of the panel setting memory buttons, so that the keyboard 3 can change the tone of the main melody playing area. .
