Electronic Percussion Drum Kit Sensitivity Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic percussion instruments require complex procedures for users to select drum kits for tone color assignments and set sensitivity, making it cumbersome to set respective sensitivities of multiple pads.
Innovation Solution
An electronic percussion instrument that allows users to set tone colors and sensitivities of pad sources simultaneously by selecting a drum kit, using a CPU, program memory, storage device, and setting operation input unit to automatically designate sensitivity settings based on link data within the selected drum kit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate procedures are used for selecting drum kits and setting sensitivity, then tone color assignments and sensitivity settings can be controlled independently, but the operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines drum kit selection and sensitivity setting into a single integrated operation. When a user selects a drum kit from the stored drum kits, the system automatically applies both the tone color assignments and the sensitivity settings associated with that drum kit, eliminating the need for separate procedures and reducing operational complexity
Solution Approach 2:
The system pre-configures drum kits with both tone color assignments and sensitivity settings stored together. This preliminary preparation allows users to access pre-packaged configurations that include both parameters, so when a drum kit is selected, all associated settings are automatically applied without requiring separate adjustment steps
2Adaptability or versatility
If drum kit selection does not change sensitivity settings, then tone color assignments can be changed independently, but the ability to set respective sensitivities of multiple pads simultaneously is lost
Solution Approach 1:
The patent merges tone color assignment and sensitivity setting into a unified drum kit configuration. Each drum kit stores both types of data together, allowing users to change both parameters simultaneously through a single selection operation, thereby improving both adaptability and operational efficiency
Solution Approach 2:
The drum kit data structure is designed to universally contain both tone color assignment data and sensitivity setting data. This multi-functional design allows a single drum kit selection to control multiple aspects of pad behavior, including both the musical tone characteristics and the sensitivity thresholds, providing comprehensive control in one operation
Data Source
AI summary
An electronic percussion instrument generates, in accordance with a trigger signal output from a pad source, a musical performance tone of a tone color assigned to the pad source. The electronic percussion instrument includes a program memory for storing a control program and a CPU for controlling operation of the electronic percussion instrument in accordance with the control program stored in the program memory. A storage device is also provided for storing a plurality of trigger data sets each of which includes at least one sensitivity setting parameter for setting sensitivity to the trigger signal, and a plurality of drum kits each of which includes pad setting data for setting the tone color assigned to the at least one pad source and link data for designating one of the plurality of trigger data sets. A setting operation input unit is provided for selecting a drum kit from among the plurality of drum kits. The CPU is coupled to the storage device and the setting operation input unit and operative under the control program for setting the sensitivity to the trigger signal on the basis of the at least one sensitivity setting parameter included in the trigger data set designated by the link data included in the drum kit selected by the setting operation input unit.
