Solution Overview
Problem
Traditional electronic musical instruments often retain mechanical layouts that were designed for mechanical instruments, which can be inefficient and cumbersome for musicians, lacking dynamic configuration options to simplify the process of playing complex musical scales and chords.
Innovation Solution
An input device with dynamically configurable chord and melody keys that use visual indicia and modular layouts to facilitate easy selection and manipulation of musical scales, allowing for real-time reconfiguration of key functions based on user input, enabling efficient play of multiple scales and chords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mechanical layouts are retained in electronic musical instruments, then structural simplicity is maintained, but musical efficiency and ease of operation deteriorate due to cumbersome playing of complex scales and chords
Solution Approach 1:
The keyboard layout is made dynamically reconfigurable, allowing keys to be reassigned in real-time based on the currently played scale. This enables the instrument to adapt its configuration to match the musical context, improving ease of operation for complex scales and chords while maintaining a simple physical structure.
Solution Approach 2:
The system changes the functional parameters of the keys based on the detected scale. When a scale is played, the corresponding scale degrees are assigned to specific keys, transforming the keyboard into a configuration optimized for that scale. This allows complex musical patterns to be played efficiently without requiring a permanently complex layout.
2Adaptability or versatility
If fixed key assignments are used, then device complexity is reduced, but adaptability to different musical contexts and scales deteriorates
Solution Approach 1:
The keyboard configuration dynamically adapts to different musical contexts by detecting the scale being played and reassigning keys accordingly. This provides versatility across multiple scales and chords while maintaining a simple fixed physical structure, avoiding the need for multiple predetermined configurations.
Solution Approach 2:
A single keyboard configuration serves multiple functions by being reassigned based on the musical context. The same physical keys can be optimized for different scales, chords, and musical patterns, providing universal adaptability without requiring multiple specialized layouts or increasing device complexity.
3Productivity
If real-time reconfiguration is implemented, then musical efficiency and ease of operation improve, but processing requirements and device complexity increase
Solution Approach 1:
The system implements real-time reconfiguration by continuously monitoring the input signal to detect scale patterns and dynamically adjusting key assignments accordingly. This enhances musical efficiency by providing context-optimal configurations without requiring complex pre-programmed sequences or extensive processing.
Solution Approach 2:
The system automatically detects the scale being played and self-configures the keyboard layout without requiring manual intervention or complex external control. This self-service approach improves musical efficiency through rapid adaptation while minimizing processing requirements by using simple pattern recognition algorithms.

AI summary
A musical input device accepts user input and generates output data indicative of musical notes. Based on a selected musical scale, a first set of keys is configured, such that each key of the first set outputs a respective chord associated with the scale. A second set of keys may be configured to output individual notes from the scale, or chords that are associated with a different scale. The keys may be provided with visible indicia, such as a color indicating the root note of a chord. Visible indicia may indicate relationships between keys, such as a melody note that matches the root note of a chord. Control keys may be used to add notes to chords or modify notes in chords, such as by adding additional octaves to the output or modifying the voicing, inversion, or spread of a chord.
