Electronic Drum Sound Routing for Independent Click Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments struggle to adjust and mix backing sounds and click sounds for output through different output units such as headphones and speakers, making it difficult for performers to balance volumes effectively for easier playing.
Innovation Solution
An electronic musical instrument that includes a sound source unit capable of acquiring and adjusting sound signals from external sources, allowing for independent volume and timing control of click and backing sounds for separate output destinations, such as headphones and speakers, through separate channels and mixing units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If backing sounds and click sounds are output through the same output unit, then the device structure is simple, but the performer cannot independently adjust volumes for different output units
Solution Approach 1:
The sound signal processing device divides the audio output into separate channels: a first sound signal channel for backing sounds and a second sound signal channel for click sounds. This segmentation allows independent volume adjustment and timing control for each sound type, enabling the performer to optimize audio for different output units (headphones vs. speakers) without increasing physical device complexity.
Solution Approach 2:
The device introduces a sound signal processing unit as an intermediary between the audio source and the output units. This intermediary component handles the complex tasks of volume balancing, timing adjustment, and channel separation, allowing simple physical architecture while achieving sophisticated audio control through software-based signal processing.
2Ease of operation
If click sound and backing sound are output simultaneously to the same destination, then the output path is simple, but the performer cannot balance volumes for different output destinations
Solution Approach 1:
The system segments the audio output into distinct channels: a first channel for backing sounds and a second channel for click sounds. This allows the sound signal processing device to independently control volumes and timing for each channel, enabling precise volume balancing for different output destinations without requiring complex physical mixing equipment.
Solution Approach 2:
The sound signal processing device dynamically adjusts audio parameters including volume levels and timing offsets for different sound channels. By changing these parameters independently for the first and second sound signals, the system achieves flexible volume balancing for various output configurations (headphones, speakers, or combinations) through software control rather than hardware complexity.
3Adaptability or versatility
If no external mixer is used, then the device structure remains simple, but the mixing and volume balancing function is lost
Solution Approach 1:
The sound signal processing device performs multiple functions within a single integrated unit: it processes backing sounds, generates click sounds, balances volumes, adjusts timing, and routes signals to different output destinations. This multi-functionality eliminates the need for separate external mixers while maintaining comprehensive audio control capabilities.
Solution Approach 2:
The device incorporates self-service mixing capabilities where the sound signal processing unit automatically handles volume balancing and signal routing based on user inputs. The system can independently adjust parameters without requiring external mixing equipment, making the device self-sufficient while maintaining versatile audio processing capabilities.
