Electronic Musical Instrument Lyrics Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments struggle to control the progression of lyrics effectively when multiple keys are pressed simultaneously, leading to unintended advancement of lyrics.
Innovation Solution
An electronic musical instrument with a second operating element that can be positioned to control whether lyrics advance or remain static, combined with processors that manage the progression based on user operations, ensuring appropriate control during performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lyrics are advanced each time a key is pressed, then lyrics progression responds to user input, but lyrics advance too much when multiple keys are pressed simultaneously
Solution Approach 1:
The system monitors key press operations and provides feedback control by detecting whether a key is already pressed before advancing lyrics. The processor checks the current key state and only advances lyrics when an unpressed key is detected, preventing excessive advancement from simultaneous multi-key presses.
Solution Approach 2:
The lyrics advancement mechanism dynamically adjusts its behavior based on real-time key press conditions. Instead of a fixed one-key-one-lyric rule, the system adapts by continuously monitoring key states and selectively advancing lyrics based on the dynamic pattern of key presses, allowing flexible control while maintaining precision.
2Adaptability or versatility
If multiple keys can be pressed simultaneously, then musical expression flexibility increases, but lyrics control becomes difficult to manage
Solution Approach 1:
The system automatically manages lyrics progression without requiring explicit user control for each advancement. The processor self-monitors key press patterns and autonomously determines when to advance lyrics, eliminating the need for users to manually control lyrics progression while maintaining responsiveness to musical expression needs.
Solution Approach 2:
The system uses feedback from key press operations to automatically control lyrics advancement. By monitoring which keys are pressed and when, the processor autonomously advances lyrics at appropriate moments, allowing flexible musical expression while maintaining simple operation for the user.

AI summary
In an electronic musical instrument that can output stored lyrics of a song in accordance with operations by a user, a processor determines whether a pedal is on or off, and if the pedal is off, the lyric is advanced in accordance with a user operation of a keyboard, and if the pedal is on, the lyric is not advanced in accordance with a user operation of a keyboard.
