Keyboard Sensor System for Real-Time Musical Score Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating musical scores from keyboard instrument performances lack efficiency in translating user interactions into accurate musical notation, particularly in determining tunes and rhythms in real-time.
Innovation Solution
A system and method that utilize sensors to detect status changes of keyboard instrument execution devices, generating signals for tune and rhythm determination, and processing these signals to create musical scores, including user interface display and composition parameter input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to generate musical scores from keyboard performances, then the composition process can be completed, but the efficiency of translating user interactions into accurate musical notation is low
Solution Approach 1:
The patent replaces manual transcription methods with an automated sensor-based system. Sensors detect key presses, hammer movements, and string vibrations, converting mechanical performance data into digital signals that are automatically processed into musical notation, eliminating the need for manual score writing
Solution Approach 2:
The system enables self-service by automatically generating musical scores from performance data without requiring external transcription. The keyboard instrument itself, equipped with sensors and processing capabilities, performs the transcription function internally, allowing composers to obtain scores directly from their performances
2Measurement precision
If real-time detection of execution devices is implemented, then accurate tune and rhythm determination is achieved, but the system complexity increases
Solution Approach 1:
The patent segments the detection system into specialized sensors for different functions: one sensor detects key press status changes, another detects hammer position, and a third detects string vibration. This segmentation allows each sensor to be optimized for its specific measurement task, improving overall precision while managing complexity through functional specialization
Solution Approach 2:
The processing system serves multiple functions: it processes signals from multiple different sensors, determines both tune and rhythm information, generates musical notation, and allows for score modification. This multi-functionality consolidates what would otherwise require separate systems into a single integrated processing unit

AI summary
A method for generating a musical score based on user performance during playing a keyboard instrument may include detecting a status change of a plurality of execution devices of the keyboard instrument. The method may include generating a first signal according to the detected status change. The method may include generating a second signal indicating a plurality of timestamps. The method may include determining a tune of the musical score based on the first signal. The method may include determining a rhythm of the musical score based on the second signal. The method may further include generating the musical score based on the tune and the rhythm of the musical score.
