Description

Technical Field

[0001] The present invention relates to the technical field of music creation, and in particular to an intelligent chord generation method, system and storage medium. Background Art

[0002] Traditional music synthesizer chord generation technology has long faced the dual challenges of efficiency and flexibility. With existing technologies, users must manually combine notes or enter a multi-layered menu to select a chord type. This process is cumbersome and time-consuming, and especially in real-time performance scenarios, the complex input method severely limits the fluency of creation. Furthermore, traditional synthesizers often use a standard piano key layout. While this conforms to conventional playing habits, the large number of keys and bulky size not only take up space but also increase portability, making it difficult to adapt to the miniaturized and mobile demands of modern music production.

[0003] Crucially, traditional synthesizers' parameter adjustments (such as timbre, effects, and rhythm) are separated from performance operations, requiring users to interrupt their performance to adjust menus or knobs, significantly reducing dynamic expressiveness. These shortcomings collectively contribute to the high barrier to entry for music creation and the lack of real-time interactivity of existing technologies, making it difficult to meet the needs of professional performers and amateur users for efficient and intuitive arrangement tools. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an intelligent chord generation method, which includes the following steps:

[0005] Get the user's selected scale, chord type and root note information through the physical encoder and chord type shortcut keys;

[0006] According to the scale, chord type and root note information set by the user, the frequency of the waveform is modulated by the modulator, and the corresponding chord timbre characteristics are generated based on the principle of FM synthesizer;

[0007] Acquire and correct the chord timbre characteristics based on preset chord rules to obtain the target chord;

[0008] Obtain and coordinate the target chord and bass part according to the bass part parameters, adjust the arrangement rules of the chord and bass part in real time, and realize the coordinated performance of the chord and bass part.

[0011] Optionally, the clip recorded by the LOOP function encoder is automatically associated with the rhythm speed set by the BPM function encoder;

[0012] When the tempo set by the BPM encoder changes, the recorded clip automatically adapts to the new tempo while maintaining the pitch.

[0013] Optionally, the preset chord rules include chord composition rules and harmony principles in music theory.

[0014] Optionally, obtaining and correcting the chord timbre characteristics based on preset chord rules to obtain a target chord includes at least the following steps:

[0015] Get preset chord rules;

[0016] Compare the chord timbre characteristics with the preset chord rules to determine whether the chord timbre characteristics meet the harmony requirements of the chord composition. If not, automatically correct it;

[0017] The corrected notes are recombined to form a complete target chord to obtain the target chord.

[0018] Optionally, the method further includes: dynamically adjusting the loudness and timbre characteristics of the target chord according to the pressure applied by the user to the keyboard keys.

[0019] Optionally, the keyboard keys use capacitive pressure sensors with preset graded force responses; a user lightly presses the keyboard keys to trigger a single tone, and a user presses the keyboard keys hard to increase the overall volume.

[0020] Corresponding to the intelligent chord generation method, the present invention provides an intelligent chord generation system, which includes:

[0021] The data acquisition module is used to obtain the user's selected scale, chord type and root note information through the physical encoder and chord type shortcut keys;

[0022] The chord generation module is used to modulate the frequency of the waveform through the modulator according to the scale, chord type and root note information set by the user, and generate the corresponding chord timbre characteristics based on the FM synthesizer principle;

[0024] The collaborative module is used to obtain and collaboratively process the target chord and the bass part according to the bass part parameters, adjust the arrangement rules of the chord and bass part in real time, and realize the linked performance of the chord and bass part.

[0025] In addition, to achieve the above-mentioned purpose, the present invention also provides a computer-readable storage medium, on which an intelligent chord generation program is stored.

[0037] like Figure 1 As shown, an intelligent chord generation method of the present invention includes the following steps:

[0038] Get the user's selected scale, chord type and root note information through the physical encoder and chord type shortcut keys;

[0039] According to the scale, chord type and root note information set by the user, the frequency of the waveform is modulated by the modulator, and the corresponding chord timbre characteristics are generated based on the principle of FM synthesizer;

[0040] Acquire and correct the chord timbre characteristics based on preset chord rules to obtain the target chord;

After the user presses the chord type shortcut key, the system automatically generates chord notes that conform to the rules based on the scale selected by the user, avoiding manual input errors. For example, if the user selects C major (select C major by adjusting the Key function encoder) and presses the Maj key, the system automatically generates a CEG chord.

[0043] In this embodiment, the bass part parameter is the volume of the bass chorus.

[0044] In this embodiment, the corresponding polyphonic timbre characteristics are generated based on the principle of FM synthesizer, specifically, the corresponding polyphonic timbre characteristics are generated through the frequency modulation interaction between the modulator and the carrier signal.

It is easy to operate and conforms to the user's playing habits. Based on this information, the chord timbre characteristics are generated using the modulator and FM synthesizer principles, which can efficiently create a rich and diverse chord timbre. The timbre characteristics are then corrected based on preset chord rules to ensure the harmony and accuracy of the chords and avoid dissonance affecting the musical effect.

[0050] Preferably, the system configuration includes at least storage presets, battery level display, audio output mode (MIDI / 3.5mm), key sensitivity adjustment, etc.

[0051] Through the correlation and automatic adaptation function between the LOOP function encoder and the BPM function encoder, the present invention can automatically adapt the recorded segment without changing the pitch when the rhythm speed changes. This greatly improves the flexibility and efficiency of music creation, avoids pitch errors caused by rhythm speed adjustment, and facilitates users to create and modify music at different rhythm speeds.

[0052] In this embodiment, the segment recorded by the LOOP function encoder is automatically associated with the tempo set by the BPM function encoder;

[0053] When the tempo set by the BPM encoder changes, the recorded clip automatically adapts to the new tempo while maintaining the pitch.

[0055] In this embodiment, the preset chord rules include chord composition rules and harmony principles in music theory.

[0056] Chord construction rules are specific to preset chord structures, for example:

[0057] Dim (diminished chord) chord structure: root note + minor third + diminished fifth.

[0058] Min (minor chord) chord structure: root note + minor third + perfect fifth.

[0059] Maj (major chord) chord structure: root note + major third + perfect fifth.

[0060] Sus (Suspended Chord) Chord Structure:

[0071] Determine whether the chord timbre characteristics meet the harmony requirements of chord composition. Specifically, determine whether the generated chord note exceeds the scale range (such as F# in C major). If the generated chord note exceeds the scale range, replace it with the nearest legal note (F).

[0076] Preferably, the keyboard keys are specifically a 12-key compact keyboard, including 7 white keys (CDEFGAB) and 5 black keys, and the black keys are semitone keys for sharp or flat tuning.

[0077] The keyboard keys of the present invention adopt capacitive pressure sensors and graded force response.
