Electronic Keyboard Instrument Performance Detection Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic musical instruments face challenges in distinguishing between musical performance and non-performance operations, leading to unintended execution of switching processes that can hinder performance or increase player workload.
Innovation Solution
The electronic keyboard instrument employs a processor to determine if musical performance is being conducted based on key and pedal operations, and controls the execution of switching processes accordingly, particularly in AUTO mode, to prevent unwanted process execution and reduce player workload.

Engineering Contradiction Analysis
1Ease of operation
If switching processes are executed in response to operator operations during musical performance, then the instrument responds to player input, but unintended process execution interrupts performance and increases player workload
Solution Approach 1:
The system continuously monitors musical performance status through feedback from musical performance operators (keyboard, pedals) and uses this feedback to dynamically control whether switching processes execute in response to function operator operations. During active performance, the system suppresses switching process execution, preventing interruptions while maintaining normal performance response.
Solution Approach 2:
The instrument's operational mode is made dynamic, automatically adapting between performance mode (suppressing switching processes) and non-performance mode (allowing switching processes). This dynamic behavior allows the system to respond to player intentions without causing interruptions during active playing.
2Reliability
If the instrument continuously monitors performance status, then switching processes are controlled appropriately, but additional processing requirements are imposed
Solution Approach 1:
The processor performs multiple functions using a unified approach: it monitors musical performance status, determines operational mode, and controls switching process execution all through the same processing logic. This multi-functional design avoids adding separate complex monitoring systems while achieving reliable performance status detection.

AI summary
An electronic musical instrument includes at least one function operator associated with at least one process, and at least one processor, wherein the at least one processor executes the followings, deciding that musical performance is being performed or not in response to an operation to the at least one function operator, in response to deciding that the musical performance is being performed, executing the at least one process associated with the at least one function operator, and in response to deciding that the musical performance is not being performed, not executing the process associated with the at least one function operator, despite being operated to the at least one function operator.
