Background

Chord, a concept of music theory, refers to a group of sounds in a certain interval relationship. Three or more tones are combined in the longitudinal direction in a three-degree overlapping relationship to form a chord. There are usually concepts of three chords (three-note chords), seven chords (four-note chords), nine chords, etc., among which the common chords are, for example, C, Dm, Am, F, G, etc. The chord formed according to the relation of three-degree interval is widely adopted because the tone keeps a certain tension, the sound is harmonious and full, and conforms to the natural law of overtones.

Specifically, in this embodiment, the music chord generating device of the present invention has a main switch, when the main switch is turned on, the main controller 4 generates a corresponding sensing calibration instruction to calibrate each sensing module 1, and when no string 2 is touched, the music chord generating device enters a sleep state, at this time, the main controller 4 generates a corresponding sleep display instruction and sends the sleep display instruction to the heartbeat lamp control module, and the heartbeat lamp of the light control module 6 flashes correspondingly to present the breathing lamp effect.

When any string 2 is touched, the music chord generating device is awakened, the string 2 is preferably triggered by capacitive touch, an operator touches any string 2 by fingers, the sensing module 1 connected with the string 2 senses touch and also senses stop touch, the sensing module 1 detects real-time state data of each string 2 connected with the sensing module 1 in real time, namely whether the string is currently touched or not, the real-time state data is transmitted to the sub-controller 3 through an I2C bus, and the sub-controller 3 is preferably a single chip microcomputer. In this embodiment, 8 sensing module 1 are preferred to be connected to a singlechip, and 12 strings 2 are preferred to be connected to every sensing module 1, consequently, can monitor 96 strings under a singlechip full-match state, if more strings of needs, can expand the quantity of singlechip as required.

And starting timing when the music chord generating device starts to work, namely starting timing when a main switch of the music chord generating device is started, and calculating to obtain the chord corresponding to the timing result according to the timing result and the preset duration of each music piece. For example, song 1, song 2, and song 3 are sequentially stored in the music chord generating device, the duration of song 1 is 100 seconds, the duration of song 2 is 110 seconds, the duration of song 3 is 120 seconds, and if the timing result is 90 seconds, that is, only after the music chord generating device is turned on for 90 seconds, there is string 2 touched, the calculated chord is the chord corresponding to the 90 th second of song 1; if the timing result is 220 seconds, the calculated chord is the chord corresponding to the 10 th second of song 3; if the timing result is 340 seconds, the calculated chord is the chord corresponding to the 10 th chord of song 1, and so on.

After the chord to be output by the string 2 is obtained, the master controller 4 correspondingly processes the chord to obtain the note corresponding to the string 2. Because there are 7 local tones and 5 downnotes in each octave of the music, it is possible to select how much the note needs to be tuned according to any note in a range if the note is to be tuned to a certain chord. For example n is the total number of strings touched and n ranges from 0 to 95. When the general controller 4 receives the n strings touched, it can calculate what note should be actually output from the value of n by only judging the current chord. The specific treatment process is as follows:

1) if the current chord is C, only three notes of C, E and G can be output, so the processing method of the C chord is as follows:

k is equal to 0 inside n × 4+0 "+ 0" because the C chord is the most basic reference chord position and other chords are added with positive numbers;

if ((k + 4)% 12 ═ 0) k ═ k-1k is used for representing the notes that need to be played by the string, finding out those notes whose k is the 5 th note of this octave, and adapting them to be the falling notes;

2) if the current chord is D, only three notes of D, F #, and A can be output, so the processing method of the D chord is as follows:

the "2" inside k ═ n × 4+2 "+ 2" is because the D chord is two notes higher than the C chord, so 2 needs to be added;

if ((k + 2)% 12 ═ 0) k ═ k-1k is used for representing the notes that need to be played by the string, finding out those notes whose k is the 5 th note of this octave, and adapting them to be the falling notes;

3) if the current chord is a minor chord, such as Dm, only three notes, D, F, and A, can be output, so the Dm chord is processed by:

k is "2" inside n × 4+2 "+ 2" because Dm chord is two notes higher than C chord, so 2 needs to be added;

if ((k + 2)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and those 5 th note with k being only the octave are found and are adapted to be the downnote;

4) if the current chord is E, only three notes D, F #, and A can be output, so the processing method of the D chord is as follows:

k is "4" inside n × 4+4 "+ 4" because the E chord is four notes higher than the C chord, so 4 needs to be added;

if ((k + 2)% 12 ═ 0) k ═ k-1k is used for representing the notes that need to be played by the string, finding out those notes whose k is the 5 th note of this octave, and adapting them to be the falling notes;

5) if the current chord is Em, only three notes of E, G and B can be output, so the processing method of the Em chord is as follows:

k is "4" inside n × 4+4 "+ 4" because Em chord is four notes higher than C chord, so 4 needs to be added;

if ((k + 4)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and those 5 th note with k being only the octave are found and are adapted to be the downnote;

if (k% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and 3 rd note with k being only the octave is found and is adapted to be a downnote;

6) if the current chord is F, only three notes of F, a, and C can be output, so the F chord is processed by:

k is "5" inside n × 4+5 "+ 5" because F chord is five notes higher than C chord, so 5 needs to be added;

if ((k-1)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, finding out the 5 th note with k being only the octave, and adapting to the descending note;

7) if the current chord is F #, only three notes of F #, A #, and C # can be output, so the processing method of the F # chord is as follows:

the "6" inside k ═ n × 4+6 "+ 6" is because F # chord is six notes higher than C chord, so 6 needs to be added;

if ((k-2)% 12 ═ 0) k ═ k-1k is used for representing the notes that need to be played by the string, finding out those notes whose k is the 5 th note of this octave, and adapting them to be the falling notes;

8) if the current chord is G, only three notes of G, B and D can be output, so the processing method of the G chord is as follows:

k is "5" inside n × 4+7 "+ 7" because the G chord is seven notes higher than the C chord, so 7 needs to be added;

if ((k-3)% 12 ═ 0) k ═ k-1k is used for representing the notes that need to be played by the string, finding out those notes whose k is the 5 th note of this octave, and adapting them to be the falling notes;

9) if the current chord is A, only three notes of A, C #, and E can be output, so the processing method of the chord A is as follows:

10) if the current chord is Am, only three notes of A, C and E can be output, so the processing method of the Am chord is as follows:

the reason why k is "9" inside n × 4+9 "+ 9" is that Am chord is nine notes higher than C chord, so 9 needs to be added;

if ((k-1)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and those 5 th note with k being only the octave are found and are adapted to be the downnote;

if ((k-5)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and 3 rd position notes with k being only the octave are found and are adapted to be the downnote;

11) if the current chord is Bm, only three notes of B, D and F # can be output, so the processing method of Am chord is as follows:

the reason why k is "9" inside n × 4+11 "+ 11" is that since Bm chord is eleven notes higher than C chord, 11 needs to be added;

if ((k-3)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and those 5 th note with k being only the octave are found and are adapted to be the downnote;

if ((k + 5)% 12 ═ 0) k ═ k-1k is used for representing the notes to be played by the string, and 3 rd home notes with k being only the octave are found and are adapted to be the downnote;

the general controller 4 needs to further determine through which virtual instrument the note is played when calculating the note output by the current chord. The master controller 4 stores the corresponding relation between the total number of all the strings and a plurality of preset virtual musical instruments; such as: the virtual musical instruments corresponding to the numbers 0 to 11 are pianos, and the virtual musical instruments corresponding to the numbers 12 to 15 are guitars and the like; therefore, the general controller 4 can determine which kind of virtual instrument plays the note corresponding to the chord according to the total number of the touched string 2, and generate a corresponding control instruction to play the note corresponding to the virtual instrument.

Further, in this embodiment, a communication interface between the master controller 4 and the slave controller 3 is an RS-232 serial port on a physical layer, a bit rate is designed to be 250000bps, a data bit is 8 bits, a check is set to none, and a stop bit is 1 bit. The master controller 4 can control the sub-controller 2 to carry out sensor calibration on the sensing module 1 in a DTR mode through the serial port connection. After the calibration is completed, the sub-controllers 2 need to send a piece of READY-X: Y information to the main controller 4, wherein X is the serial number of the sub-controllers 2, and Y is the serial number of the sensing module 1. The sub-controller 2 needs to send corresponding information to the overall controller when two events occur, which are: 1) when the string is touched 2) when the string stops being touched.
