Sound Control Device Dynamic Mode Switching for MIDI Operator Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound control devices face challenges in improving operability for layered sound production, as they require pre-setting flags for external sound sources, leading to increased complexity and cost, and underutilization of operators due to invalid timbre settings.
Innovation Solution
A sound control device with multiple setting interfaces, a communication interface for MIDI control change messages, a designator for validity, and a mode selector to control message transmission based on timbre validity, allowing for effective use of operators by distinguishing between valid and invalid timbre settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flags are set in advance for external sound sources, then sound parameters can be controlled, but operability deteriorates because it is difficult to change sound parameters freely in a live hall
Solution Approach 1:
The patent implements dynamic switching between two control modes: a first mode where control change messages for valid timbres are not transmitted (using internal sound source) and a second mode where they are transmitted (using external sound source). This dynamic mode switching allows the system to adapt between different operational requirements, enabling free parameter changes in live hall settings while maintaining structured control when needed.
2Ease of operation
If a setting unit is provided exclusively for the external sound source, then external sound control is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes existing setting units serve multiple functions by enabling them to control both internal and external sound sources depending on the selected mode. The same setting units that normally control internal sound sources can also control external sound sources when the second mode is selected, eliminating the need for separate dedicated setting units and reducing overall system complexity.
3Device complexity
If operators are designated as invalid for certain timbres, then sound control is simplified, but operator utilization deteriorates because operations are not reflected in sound control
Solution Approach 1:
The patent dynamically changes the function of operators based on the selected mode. In the first mode, operators control internal sound sources. In the second mode, the same operators control external sound sources. This dynamic reassignment ensures that operators are always utilized effectively regardless of the mode, eliminating waste while maintaining clear control pathways.

AI summary
A sound control device includes a plurality of setting interfaces. Each of the setting interfaces includes a parameter operator, a communication interface performing control change message transmission and reception, a generation unit generating the control change message, a designation unit designating validity or invalidity of generating respective sound signals for the plurality of setting interfaces, a mode selection unit selecting a control mode of the communication interface, and a control unit. The control unit controls such that, when a first mode is selected, the control change message generated by the generation unit for a setting interface which is designated as valid among the plurality of setting interfaces is not transmitted through the communication interface, and the control change message generated by the generation unit for a setting interface which is designated as invalid among the plurality of setting interfaces is transmitted through the communication interface.
