Visual Tone Control Interface for Electronic Music Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic music apparatuses lack intuitive control of tone color effect parameters, as users cannot visually control these parameters and cannot easily associate control operating members with tone color effect parameters, leading to cumbersome settings and limited control freedom.
Innovation Solution
An electronic music apparatus with a display device showing a first and second display object, where the position of the first object varies with control member operation, determining a control value for the tone color effect parameter based on the positional relationship, allowing intuitive control and association of the control member with the parameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional electronic music apparatus display parameter values in numerical form, then the device complexity is reduced, but the ease of operation deteriorates because users cannot intuitively grasp control values or visually control parameters
Solution Approach 1:
The patent transforms the one-dimensional numerical display into a two-dimensional visual control interface. Display objects are positioned on a screen plane where their spatial relationships encode parameter values, allowing users to intuitively grasp control values through visual positioning rather than numerical interpretation.
Solution Approach 2:
The patent introduces display objects as intermediary elements between the control operating member and the tone color effect parameter. These visual objects mediate the control process by representing parameter values and control relationships graphically, enabling intuitive visual control without increasing fundamental device complexity.
2Productivity
If multiple tone color effect parameters are controlled simultaneously by one control operating member, then the productivity is improved, but the device complexity increases due to complicated setting operations
Solution Approach 1:
The patent makes the display device universal by enabling it to represent multiple tone color effect parameters simultaneously through multiple display objects. The same visual interface and control mechanism can control different parameters by simply changing which parameters are assigned to display objects, eliminating the need for different control mechanisms for each parameter.
Solution Approach 2:
The patent introduces dynamic parameter assignment where the control operating member can be flexibly assigned to control different tone color effect parameters at different times. The system dynamically adjusts which parameters are controlled based on user selection, allowing efficient simultaneous control without fixed complex wiring.
3Adaptability or versatility
If tone color effect parameters are associated with control operating members in advance, then the ease of operation is improved, but the adaptability deteriorates because users cannot easily change control styles
Solution Approach 1:
The patent performs preliminary association of display objects with tone color effect parameters before the control operation begins. This preliminary setup allows the system to be ready for immediate intuitive control while maintaining the flexibility to reconfigure associations later, balancing ease of operation with adaptability.
Solution Approach 2:
The patent enables dynamic parameter changes by allowing users to modify which tone color effect parameters are assigned to display objects and control operating members. The system supports changing control styles by reassigning parameters without requiring complex reconfiguration, maintaining ease of operation while improving adaptability.

AI summary
First display object associated with a control operating member and a second display object associated with a tone color effect parameter are displayed, and variation of a displayed position of the first display object is controlled in accordance with operation of the control operating member. Control value of the tone color effect parameter is determined in response to variation in relationship between the first and second display objects, and tone control is performed on the basis of the determined control value. Further, the variation of the displayed position of the first display object is controlled so as to move on and along a set path, so that displayable positions of the first display object is limited to the set path. Control value of the tone color effect parameter is determined on the basis of relationship between displayed position of the first and second display objects to perform tone control.
