Tone Generation Assigning Apparatus for Natural Ensemble Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments struggle to generate ensemble performances naturally, often resulting in unnatural or uncomfortable feelings due to uniform tone generation across all performance parts, failing to account for the characteristics of different musical instruments and key depression states.
Innovation Solution
A tone generation assigning apparatus and method that allows independent assignment of tone colors to specific tone pitches by multiple assigners, each with unique priority rules and selection modes, enabling flexible tone generation that considers the characteristics of individual instruments and key depression states, ensuring natural ensemble performances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform tone assignment is applied across all performance parts, then the system is simple to operate, but the ensemble performance becomes unnatural and uncomfortable
Solution Approach 1:
The patent divides the tone generation system into multiple independent assigners (first assigner, second assigner, third assigner, fourth assigner), each responsible for assigning tone colors to specific performance parts. This segmentation allows each assigner to operate independently with its own priority rules, enabling natural ensemble performance while maintaining operational simplicity through modular design.
Solution Approach 2:
Each assigner is configured with different priority rules tailored to specific performance parts. For example, the first assigner uses last-depressed key priority for melody instruments, while the second assigner uses higher-pitch note priority for harmony instruments. This local customization of assignment rules ensures that each performance part receives appropriate tone colors based on its musical role, creating natural ensemble performances.
2Reliability
If multiple assigners with independent priority rules are used, then natural ensemble performance is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple assigners into a single tone generation apparatus, where each assigner works in parallel to handle different performance parts. The assigners share common resources such as the tone color database and tone generation unit, reducing overall system complexity while maintaining the benefits of independent assignment rules for each performance part.
Solution Approach 2:
Each assigner is designed as a multi-functional module that can handle different types of tone color assignments (melody, harmony, rhythm, etc.) by switching between different priority rules. This universality reduces the need for separate specialized modules for each performance part, thereby reducing device complexity while maintaining natural ensemble performance.

AI summary
Tone generating instructions designating one or more tone pitchesare received in response to performance operation on a keyboard, for example. A plurality of assigners are provided to assign tone colours to the one or more tone pitches designated by the received tone generating instructions. The plurality of the assigners are configured to select, for each assignor, from among the one or more tone pitches designated by the one or more tone generation instructions received by a reception section, one or more target tone pitches to which the tone color is to be assigned by the assigner, and determine, for each assignor and on the basis of a priority order set for each assigner, from among the selected one or more target tone pitches, one or more tone pitches of which tones are to be generated with the tone color assigned by the assigner.
