Step Sequencer RGB Button Grid for Live Performance Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Musical step sequencers lack intuitive and flexible control over sound temporal placement and synchronization, particularly in live performance settings with unfavorable conditions, where identifying button positions can be challenging due to poor lighting.
Innovation Solution
A 4×16 grid of soft-touch RGB buttons on a hardware controller that allows users to program and control sound patterns by pressing buttons to select temporal locations within a pattern, with additional features like dividers for visual and tactile guidance, shift and alt buttons for expanded functions, and LED illumination indicating sound frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional row of buttons is used to program sound sequences, then the device can control temporal location of sounds, but the buttons become difficult to identify in poor lighting conditions during live performance
Solution Approach 1:
The patent applies color changes by implementing LED illumination beneath each button that changes color based on the sound frequency being played. This allows users to identify button functions and temporal locations through color coding rather than relying on visual inspection of button positions in dark performance environments, directly resolving the contradiction between ease of operation and illumination intensity.
2Adaptability or versatility
If multiple rows of buttons are used to control different sound patterns, then the device gains versatility in sound control, but the complexity of identifying and operating specific buttons increases
Solution Approach 1:
The patent uses color changes to differentiate between multiple sound patterns and temporal locations across multiple rows of buttons. Each button emits light in a specific color corresponding to its function, allowing users to quickly identify which button controls which sound pattern without needing to memorize complex button layouts, thus maintaining versatility while reducing operational complexity.
Solution Approach 2:
The patent implements feedback by providing real-time visual indication through LED illumination when buttons are pressed or when sounds are played. This feedback mechanism helps users understand the current state of the sequencer and which buttons correspond to which sounds, simplifying the operation of multi-row button grids and reducing the cognitive load required to navigate the device's versatility.
3Ease of operation
If dividers are added to the button grid for visual and tactile guidance, then the ease of locating specific buttons improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the button grid into sections using physical dividers that create distinct visual and tactile zones. These dividers segment the large grid into smaller, more manageable sections, making it easier for users to locate and operate specific buttons without increasing overall device complexity, as the dividers are simple structural elements rather than complex mechanisms.
