Single Controller Content Control Device for Musical Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments require multiple controllers to vary multiple sound parameters simultaneously, making real-time performance adjustments cumbersome and difficult to manage.
Innovation Solution
A content control device and method that allows a single operation unit to select a playback section and output multiple parameter values based on control data, enabling simultaneous variation of sound parameters using a single controller, such as a master knob, across different sections of a musical piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple controllers are used to vary multiple sound parameters simultaneously, then the sound parameter control capability is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
A single controller is designed to perform multiple functions by selectively varying different sound parameters based on the current playback section. The controller can vary pitch, timbre, volume, or other parameters depending on which playback section is active, allowing one controller to replace what would traditionally require multiple controllers.
Solution Approach 2:
The controller's function is made dynamic by automatically changing its control target based on the playback section. As the playback section changes, the controller dynamically adjusts which parameter it controls, enabling versatile sound parameter variation without requiring physical multiplication of controllers.
2Adaptability or versatility
If multiple controllers are used to vary multiple sound parameters simultaneously, then the sound parameter control capability is improved, but the ease of operation worsens
Solution Approach 1:
The system automatically determines which playback section is current and selects the appropriate parameter for the controller to vary. This self-service mechanism eliminates the need for the operator to manually configure multiple controllers, as the system autonomously manages the mapping between the single controller and the relevant sound parameter based on playback progress.
Solution Approach 2:
The controller automatically adapts its function based on the playback section, dynamically switching control targets without requiring operator intervention. This dynamic behavior simplifies operation by allowing the performer to focus on musical expression rather than controller configuration.
3Ease of operation
If a single controller is used to control multiple parameters, then the ease of operation is improved, but the adaptability to control different parameters in different sections worsens
Solution Approach 1:
The controller is equipped with dynamic parameter selection capability that automatically adjusts which sound parameter it controls based on the current playback section. This allows a single controller to maintain operational simplicity while adapting its control target to provide versatile parameter variation across different musical sections.
Solution Approach 2:
The system pre-configures control mappings for different playback sections, so when a section is selected, the appropriate parameter control is already prepared and activated. This preliminary setup enables the single controller to seamlessly adapt to different parameters without requiring real-time reconfiguration by the operator.

AI summary
According to an exemplary embodiment, a content control device for a content divided into multiple playback sections includes at least one memory storing executable instructions and a processor that implements the executable instructions to execute a plurality of tasks. The plurality of tasks include a selecting task, a first acquiring task and an outputting task. The selecting task selects a playback section among the multiple playback sections. The first acquiring task acquires a first operation value in response to an operation of a first operation unit. The outputting task that outputs a plurality of parameter values. The plurality of parameter values are used for varying the content in the selected playback section, corresponding to the acquired first operation value based on control data that defines a relationship between the first operation value and the plurality of parameter values.
