Auto-Detecting Duo Mode for Electronic Musical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic musical instrument systems, when two performers are supposed to perform in split mode but forget to switch the mode, the performance starts on a normal mode keyboard, requiring a restart after mode switching, disrupting the performance flow.
Innovation Solution
A performance system with a primary and secondary unit that automatically detects the connection of multiple receivers and sets the electronic musical instrument to duo mode, allowing seamless performance by multiple individuals by dividing the keyboard into key regions, and communicates mode settings through a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual mode switching is required for split mode, then the keyboard can be divided into key regions for multiple performers, but the performance flow is disrupted when performers forget to switch mode
Solution Approach 1:
The system automatically detects when multiple receivers are connected and switches the keyboard to split mode without requiring manual intervention from performers. The determining portion evaluates receiver connections and the transmitting portion automatically sets the mode, making the system self-configuring and eliminating the need for performers to manually switch modes during performance preparation.
Solution Approach 2:
The system performs mode switching in advance based on receiver connection detection before the performance actually starts. By detecting receiver connections during the setup phase and automatically configuring split mode beforehand, the system ensures the keyboard is properly configured before performers begin playing, preventing disruptions during the performance itself.
2Ease of operation
If automatic mode detection is implemented, then performance continuity is maintained, but the device complexity increases
Solution Approach 1:
The determining portion and transmitting portion are integrated into the existing electronic musical instrument system, allowing the same hardware components to serve both traditional manual mode switching functions and automatic detection functions. The system uses existing communication interfaces and control mechanisms to achieve automatic mode detection without adding substantial new hardware complexity.

AI summary
A performance system can include a primary unit and a secondary unit. The secondary unit is provided for an electronic musical instrument that can be set to a first mode that enables performance by a single individual and a second mode that enables performance by a plurality of individuals, has connecting portions enabling connection of one or a plurality of receivers having at least a receiving function, and is able to communicate with the primary unit. The performance can also include an determining portion for determining whether or not a plurality of the receivers is connected to the connecting portion, and a transmitting portion for transmitting, to the primary unit, a notification that the second mode has been set, upon determining that a plurality of the receivers has been connected to the connecting portion. The secondary unit can include a setting portion for setting the electronic musical instrument to the second mode upon a determination that a plurality of receivers has been connected to the connecting portion.
