Electronic Music Instrument Control Octave Remapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MIDI keyboards often transpose the control octave out of the playable range when adjusting the note range, making the control octave's functionality inaccessible.
Innovation Solution
An electronic music instrument with a software module that remaps non-sounding control input elements based on the transposition state of the input device, ensuring they remain within the playable range and providing visual indicators for easy identification, allowing the player to control sound parameters without losing access to control functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard transposes the note range to match the intended range, then the playable note range is improved, but the control octave focus moves out of the playable range making control functions inaccessible
Solution Approach 1:
The control octave is made dynamic by automatically repositioning it based on the current transposition state. Instead of being fixed, the control octave dynamically adjusts its position within the keyboard range to remain accessible regardless of transposition, resolving the contradiction between adaptable note range and accessible control functions
Solution Approach 2:
The system changes the parameter of control octave position based on the transposition state. When transposition occurs, the control octave's position parameter is automatically adjusted to maintain accessibility, allowing both full note range adaptability and continuous control function accessibility
2Ease of operation
If visual indicators are added to indicate control input elements, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Visual indicators use color coding to distinguish control input elements from other keys. This simple visual differentiation method improves ease of operation without significantly increasing device complexity, as it leverages existing LED or lighting capabilities rather than adding complex mechanical or electronic systems

AI summary
An electronic music instrument comprises an input device having a plurality of input elements configured for generating at least one digital signal corresponding to a particular note when activated, the input device configured to be organized in sounding input elements and non-sounding control input elements and configured for transposing a range of input elements to an intended range of notes; and a software module, wherein the software module is configured for receiving a transposition state of then input device and for remapping the control input elements according to the transposition state.
