Musical Sound Processing Apparatus Dynamic Tempo Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical sound processing systems lack the ability to dynamically adjust the timing of musical tones based on external timing information, limiting the generation of complex and interesting musical sounds.
Innovation Solution
A musical sound processing apparatus with a first control unit that controls the timing of a first tone according to a first tempo and a second control unit that controls the timing of a second tone, allowing the use of either tempo based on the presence or absence of external timing information, thereby adjusting the interval between tones and generating musical sounds with varying interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the timing of the first tone is controlled according to a fixed first tempo, then the musical sound processing is simple and stable, but the ability to generate complex and interesting musical sounds is limited
Solution Approach 1:
The patent implements dynamic tempo switching by allowing the first control unit to select between a fixed first tempo and a variable second tempo based on external timing information. This enables the system to adapt its timing characteristics dynamically, generating diverse musical expressions without requiring permanently complex control structures.
Solution Approach 2:
The system changes the tempo parameter from a fixed first tempo to a variable second tempo derived from external timing information. This parameter change allows the musical sound processing apparatus to generate complex rhythms and patterns while maintaining a relatively simple base control structure.
2Adaptability or versatility
If the timing of the first tone is controlled according to external timing information, then the musical expression is enhanced, but the stability and simplicity of the timing control is reduced
Solution Approach 1:
The system dynamically adjusts between stable fixed tempo mode and flexible external-sync mode. The first control unit can maintain stable timing using the fixed first tempo when external information is unavailable, while switching to external timing synchronization when musical expression enhancement is desired.
3Adaptability or versatility
If the interval between tones is fixed, then the timing control is simple, but the ability to create varying musical interests is limited
Solution Approach 1:
The interval between tones is changed from a fixed value to a variable parameter derived from external timing information. The second tempo, calculated based on external timing data, dynamically adjusts the interval between first tones, creating varied musical patterns without complex manual control.

AI summary
A musical sound processing apparatus, a musical sound processing method, and a storage medium capable of generating musical sound full of interest are provided. The musical sound processing apparatus includes a first control unit configured to control a timing of sounding of a first tone in steps that come with an interval therebetween and a second control unit configured to control a timing of sounding of a second tone following or overlapping the first tone according to a first tempo, wherein the first control unit is configured to control the timing of sounding of the first tone according to the first tempo when timing information has not been acquired from outside and control the timing of sounding of the first tone according to a second tempo which is based on the timing information and different from the first tempo when the timing information has been acquired.
