Performance Device Tempo and Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical performance devices cannot simultaneously adjust the tempo and position of a performance naturally, often resulting in unnatural sound when trying to synchronize with other music, as they either stop or step forward awkwardly during adjustments.
Innovation Solution
A performance device with an operator, time calculation means, tempo setting means, storage means, performance means, and display means that allows for changing the performance position and tempo using a single operator, where the position changes only on the initial operation and tempo adjusts based on the time interval, ensuring natural performance without stopping or stepping forward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the performance position is adjusted by repeated tap operations, then the performance position can be changed, but the performance stops or steps forward producing an unnatural performance feeling
Solution Approach 1:
The system dynamically changes its response to tap operations based on the current state. The first tap operation triggers a performance position change (reset to beginning), while subsequent tap operations trigger tempo adjustments. This dynamic state-dependent behavior allows the same operator to serve dual purposes without causing performance interruptions.
Solution Approach 2:
The tap operation functionality is segmented into two distinct modes: position adjustment mode (activated by the first tap) and tempo adjustment mode (activated by subsequent taps). This segmentation allows each function to operate independently without interfering with performance continuity, resolving the contradiction between ease of operation and performance reliability.
2Device complexity
If a single operator is used for both position and tempo adjustment, then device complexity is reduced, but it becomes difficult to distinguish when position changes versus tempo changes
Solution Approach 1:
The system provides visual feedback through a display device that shows different states (e.g., position reset state versus tempo adjustment state). This feedback mechanism allows the operator to understand which function will be triggered by the next tap operation, making the single operator's dual functionality clear and intuitive without adding device complexity.
3Adaptability or versatility
If the performance position is changed to coincide with another performance, then synchronization is achieved, but the tempo may need adjustment which complicates the operation
Solution Approach 1:
The single operator serves multiple functions: it can change performance position, adjust tempo, and both functions contribute to achieving synchronization with another performance. This multi-functionality eliminates the need for separate controls while maintaining operational simplicity, as the operator can sequentially perform position adjustment and tempo adjustment to achieve the desired synchronization.

AI summary
A timer may be for timing a current time period corresponding to an amount of time since a previous operation of an operator. Circuitry may be for processing data to carry out a performance based on a set tempo. The circuitry may be configured to change a position of the performance to a specified position of the performance in a case where the operator is operated and the current time period equals or exceeds a specified time period. The circuitry may be configured to change the tempo based on the current time period in a case where the operator is operated and the current time period is less than the specified time period.
