Helps users to interpret the music more abundantly.

In the process of playing music with the electronic keyboard, in most cases, the user will use the right hand to play the main melody of the music, and the left hand to play the chord or accompaniment that matches the main melody. Furthermore, in order to increase the completeness and richness of the music, an accompaniment melody played with the right hand and a different instrument tone from the main melody is added to the empty beat of the main melody (that is, the place where the gap between the two phrases in the main melody is large). Also known as "air shot interpenetration") is an indispensable method of arrangement, especially in the genre of performance songs.

However, it is quite difficult for a single-layer electronic keyboard user to have both hands playing and fast and frequent tone switching at the same time when encountering music with a faster rhythm or a higher overall complexity.

Moreover, the “electrical connection” mentioned in this patent specification also refers to the “direct electrical connection” formed by the direct connection between two electronic equipment/devices/components, and the “direct electrical connection” between the two electronic equipment/devices/components. "Indirect electrical connection" formed by connecting other electronic equipment/devices/components.

Referring to FIG. 1, it is an embodiment of the electronic keyboard aerial beat sound insertion auxiliary device 1 of the present invention, which is suitable for electrical connection with the pedal device 2 and the electronic keyboard 3. Among them, the electronic keyboard aerial beat sound 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 can be, for example, a damper pedal or a switch pedal for an electronic keyboard. plate. The pedal device 2 has a switch (not shown) that 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 of the pedal being depressed or released. 2). In this embodiment, the operation signal Si is, for example, a high-state DC voltage signal, and when the pedal is continuously stepped on or triggered (for example, when the pedal is stepped on by the user), the pedal device 2 will The operation signal Si is continuously output, and when the stepping operation on the pedal is completed (the user releases the pedal), the pedal device 2 will end the output of the operation signal Si, that is, the operation signal Si is continuously output for the same length of time It is 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 tones and function settings, and an input interface unit 33 that is electrically connected to the electronic keyboard aerial shot insertion auxiliary device 1. The number of keys of the key unit 31 can be 61 or 76 keys, but not limited to this. The input interface unit 33 of this embodiment includes two input interfaces (usually higher-end electronic keyboards have more than two pedal input interfaces, the details will be described later), and the functions of sustain and tone switching can be set to these two respectively. Each input interface is controlled by the pedal. In this embodiment, the input interface unit 33 is electrically connected to the output unit 12 of the electronic keyboard air-beat penetration auxiliary device 1, so the function of sustaining and timbre switching of the electronic keyboard 3 is controlled by the electronic keyboard air-beat penetration auxiliary device 1. It is particularly noted that the electronic keyboard aerial beat penetration auxiliary device 1 can also be integrated into the pedal device 2. Therefore, in this embodiment, the sustain and tone color switching functions of the electronic keyboard 3 can be directly controlled by the pedal device 2.

The electronic keyboard 3 can control the sustain function by the pedal device 2, that is to say, when the pedal device 2 is triggered (such as pedaling), the pedal device 2 will drive the electronic keyboard aerial shot interpolation auxiliary device 1 to produce a continuous sound for the main melody When the electronic piano 3 receives the sustain signal, it will continue to sound the melody sound currently being played after the finger is released, and the melody sound output will not end until the sustain signal ends. In particular, the sustain mentioned in this manual refers to the Sostenuto function of the electronic piano, which is called selective sustain, selected sustain, specific sustain, partial sustain or sustain in Chinese.

Specifically, for example, if the sustain function is not enabled, when the user presses the key unit 31 of the keyboard 3 (for example, the central C-sound key), the keyboard 3 will output the "DO" sound corresponding to the central C-sound key. If the user keeps pressing the central C-sound key, the keyboard 3 will continue to output the "DO" sound corresponding to the central C-sound key, but once the user releases the central C-sound key, the keyboard 3 will instantly Stop outputting the "DO" sound corresponding to the central C key. However, if the electronic keyboard 3 is triggered by the pedal device 2 while the central C-sound key is pressed to activate the sustain function, the "DO" sound of the central C-sound key will continue to sound even after the key is released. The sounding stops when the sustain signal ends.

In addition, the key unit 31 of the electronic piano 3 can be divided into one or more playing areas. This embodiment 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 (generally 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 part can be set to a different instrument tone. For example, one of the parts can be the tone of the cello, and the other part can be the tone of the guzheng. In addition, each The voices can also be turned on or off separately, or all voices or only some of them can be used at the same time. A part is like a musician in an orchestra. When a certain part is assigned to use a certain tone, it is like asking the musician to play a certain instrument.

For ease of explanation, assume that the main melody playing area of the keyboard 3 has three parts, and the three parts are set to different instrument sounds, for example, the first part is set to the violin sound, and the second part is set to For the guitar tone, the third part is set as the piano tone, but it is not limited to this. When the electronic keyboard aerial beat penetration auxiliary device 1 receives the operation signal of the pedal device 2, in addition to generating a sustain signal to make the main melody sound continuously, it also generates a tone color switching signal, and the electronic keyboard 3 can use the tone color The switching signal turns on one of the three parts in sequence. For example, the user starts playing the violin tone of the first part, and when the keyboard 3 receives the tone switching signal, the first part will be turned off And enable the second part of the guitar sound. When it receives the tone switching signal again, the second part will be turned off and the third part piano tone will be enabled. If the tone switching signal is received again, the third part will be turned off and the first part will be enabled. One-part violin tone.

In this embodiment, the input unit 11 is adapted to be electrically connected to the pedal device 2 to receive the operation signal Si generated from the pedal device 2.

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, and the input interface unit 33 of the electronic keyboard 3 includes a damper pedal input interface Hole and a switch pedal input socket (not shown), the first output port 121 is suitable for electrically connecting the damper pedal input socket of the keyboard 3, and the second output port 122 is suitable for electrically connecting the switch pedal input socket of the keyboard 3 Hole, but not limited to this. It is supplemented 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, for example, the aforementioned specification may be, for example, Phone Jack, RCA, LAN, USB or MIDI, etc., but not limited to this.

The processing unit 13 in this embodiment can be a processing circuit, which can be implemented as an analog circuit, a digital circuit, an analog-digital hybrid circuit, or a single-chip microprocessor, and it can include a delayed pulse generator and a frequency divider, But it is not limited to this. According to the operation signal, the processing unit 13 generates a sustain signal for making the main melody sound continuously and a tone switching command for switching the tone of the main melody playing area. The sustain signal is used to make the electronic piano 3 sound the long notes of the main melody. , Use the free right hand to play the aerial interpenetration, and the tone switching command is used to make the keyboard 3 switch the parts of the main melody playing area so that it can output an instrument sound different from the original main melody for aerial interpenetration. The detailed description will be explained later.

In addition, it is noted that the electronic keyboard aerial shot sound penetration auxiliary device 1 in this embodiment It is implemented as a device independent of the pedal device 2 and the electronic keyboard 3, so that it can be manufactured and sold separately from the pedal device 2 and the electronic keyboard 3. The electronic keyboard aerial shot penetration assist device 1 can also be as described above The integration of the pedal device 2 or the electronic keyboard 3 is not limited to this embodiment.

In this embodiment, each time the electronic keyboard air-beat penetration auxiliary device 1 receives the operation signal Si from the pedal device 2 once, the electronic keyboard air-beat penetration auxiliary device 1 will implement the keyboard tone switching method once. The switching method is that the electronic keyboard aerial beat penetration auxiliary device 1 receives the operation signal Si, and the electronic keyboard aerial beat penetration auxiliary device 1 generates a sustain signal for continuous sounding of the main melody according to the operation signal, and a sustain signal for switching the main melody The tone color switching command of the tone of the playing area makes the keyboard 3 sound the long notes of the main melody according to the sustain signal, and the output tone of the main melody playing area is changed according to the tone switching command. The detailed description is described in the following paragraph. . By analogy, if the user has stepped on the pedal device 2 thirty times in total, the electronic keyboard air-beat insertion auxiliary device 1 will correspondingly implement the keyboard tone switching method thirty times.

Referring to FIGS. 1 to 3 at the same time, the following exemplarily describes in detail how the electronic keyboard aerial beat insertion auxiliary device 1 of this embodiment implements a single-time electronic keyboard tone color switching method.

First, in step S1, when the processing unit 13 of the electronic keyboard aerial beat penetration 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 for making the main melody sound continuously. Signal Sa and one The tone switching command Sb is used to switch the tone of the main melody playing area. In particular, the sustain signal Sa and the tone color switching command Sb are actually transmitted to the input interface unit 33 of the electronic piano 3 in the form of switch contacts, depending on the pedal polarity requirements 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, inverting the pedal polarity 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 operating signal Si. Moreover, under the premise of ignoring the signal transmission delay, the start time point and end time point of the sustain signal Sa and the operation signal Si are synchronized with each other. In addition, the sustain signal Sa is used to make the electronic piano 3, when receiving the sustain signal Sa, make the currently played melody sound continue to sound even after the finger is released, until the sustain signal Sa ends. The melody tone is output.

In addition, the tone color switching command Sb is used to enable the electronic piano 3 to switch the main melody playing area from the current part to the other of the three parts when receiving the tone color switching command Sb. In other words, the tone color switching command Sb is used to cause the electronic piano 3 to switch the musical instrument tone of the main melody playing area.

In this embodiment, each tone color switching command 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 to make the electronic piano 3 receive In the pulse wave p, the main melody playing area is switched from the current part (instrument tone) to the next part in a specific order (instrument tone) according to the pulse wave number. color). It is added that the pulse time 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 the odd number of times (the operation signal Si' shown in FIG. 2), the tone color switching instruction Sb generated by the processing unit 13 will be It is a first tone color switching command Sb' with 1 pulse wave p. On the other hand, when the processing unit 13 receives the operation signal Si for the even number of times (as the operation signal Si" shown in FIG. 2), the tone color switching command Sb generated by the processing unit 13 will have two The purpose of the second tone color switching command Sb" of the pulse wave p is to switch back and forth using only specific two parts of the three parts (skipping the third part). For example, use the first part of the violin tone to play the lead, and use the second part of the guitar tone to play the aerial shot.

After the processing unit 13 generates the sustain signal Sa and the tone color switching command Sb, then step S2 is performed.

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

The above is the description of the method for implementing the single-shot electronic keyboard tone color switching of the electronic keyboard aerial shot sound penetration system device 1.

In order to facilitate the description of the convenience of the keyboard tone switching method for the user to play the keyboard 3, here, as an example as described above, assume that the main melody playing area of the keyboard 3 is turned on the first part (violin tone) .

When the user depresses the pedal device 2 for the first time during the process of playing the electronic piano 3, the electronic keyboard air-beat insertion assisting device 1 executes the first electronic keyboard tone color switching method, and generates the first tone color in step S1 Switch the command Sb', and output the first tone color switch command Sb' to the keyboard 3 in step S2. In this embodiment, the first tone color switching command Sb' enables the electronic piano 3 to switch the main melody playing area from the first part (violin tone) to the second part (guitar tone).

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

When the user depresses the pedal device 2 for the third time, the electronic keyboard aerial shot insertion auxiliary device 1 performs the third electronic keyboard tone switching method, which causes the keyboard 3 to change the main melody playing area from the first part (violin tone) Switch to the second part (guitar tone).

Then, when the user depresses the pedal device 2 for the fourth time, the electronic keyboard aerial shot insertion assist device 1 executes the fourth keyboard tone switching method, causing the keyboard 3 to switch the main melody area from the second part (guitar tone) to the second part (guitar tone). ) Jump back to the first part (violin tone).

Therefore, by using the electronic keyboard aerial beat penetration assisting device 1 to execute the keyboard tone color switching method multiple times (that is, the pedal device 2 is stepped on multiple times), the keyboard 3 can play the main melody in the three parts. Switch back and forth between the colors of the first part and the second part.

As mentioned above, for the user, as long as the instrument tone corresponding to each part is set through the electronic keyboard 3 control panel 32 in advance, the user can use the first part (violin tone) to play the main melody of the music, and then To reach the emptiness of the main melody of the music When shooting, the user only needs to step on the pedal to make the keyboard 3 execute the main melody sustain and switch the main melody playing area to the second part (guitar tone) to play the interpenetration part. Then, at the end of the part of "Aerial Interruption", the user only needs to step on the pedal again to make the keyboard 3 switch the main melody area back to the first part (violin tone) and continue to play the main melody of the song. .

That is to say, with the keyboard tone switching method of this embodiment, the user can simultaneously sustain the keyboard 3 and automatically switch the tone with a single action of "pedaling", so that it is possible to achieve the empty beat of the main melody when the music is reached. Switch tones more smoothly at the time and play the part of "air beat interpenetration".

It is added that the application of this embodiment is used to switch the keyboard 3 main melody zone between the first and second parts of the three parts. However, if the user wants to switch from the first to the third The cyclic switching between the voice parts can be achieved as long as each tone color switching command Sb generated by the processing unit 13 has only a single pulse wave p. In addition, the electronic keyboard aerial shot sound insertion auxiliary device 1 may, for example, further include a mode selection switch (not shown) electrically connected to the processing unit 13 for switching the processing unit 13 to generate the output format of the tone color switching commands Sb, that is, to change The number and output order of pulse waves p possessed by the tone color switching commands Sb, but not limited thereto. Through the mode selection switch, the user can select several preset tone switching modes. For example, the user can choose a more complex tone switching mode, which is fixed to the first of the three parts to play the main melody, and the sound insertion part The second and third parts alternate, and its playing effect is like there are two Each musician alternately helps the lead musician to accompany the interpenetration part.

In addition, in other embodiments, the control panel 32 of the electronic piano 3 may have a plurality of (usually four) panel setting memory (One Touch memory) buttons, and the user can set each panel setting memory button to select different instrument sounds And the multiple panel setting memory buttons can be controlled by the switch pedal so that one of them can be turned on sequentially. The tone switching command Sb is used to switch the keyboard 3 from one of the multiple 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. .

Referring to FIGS. 1 and 4 at the same time, the following uses a piece of musical notation shown in FIG. 4 to exemplify the application of the electronic keyboard aerial shot insertion aid 1. As mentioned above, for the convenience of description, it is assumed that the main melody playing area of the electronic piano 3 has three parts, and the three parts are set to different instrument timbres.
