Musical Performance Device Integrating Tone Parameter Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical performance programs require users to look at virtual knob operators while operating virtual keyboards, degrading operability due to the need to check tone parameter changes, which complicates the process of outputting and changing musical sounds.
Innovation Solution
A musical performance program and device that display operation buttons with integrated tone parameter display and adjustment capabilities, allowing users to output musical sounds and change tone parameters through distinct operations, with the tone parameter displayed within the button, enabling intuitive adjustment without needing to look away from the button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual knob operators are used to change tone parameters, then tone parameter control is achieved, but operability is degraded due to the need to look at the virtual knob operators while operating keys
Solution Approach 1:
The patent combines the tone parameter control function directly into the key buttons. When a user touches or slides on a key, both the musical sound is output and the tone parameter changes are controlled through the same interface element, eliminating the need for separate virtual knob operators and improving operability.
Solution Approach 2:
The key buttons are given multiple functions: they serve both as triggers for musical sounds and as controls for tone parameters. By making the keys universal controls that can both produce sound and adjust parameters, the interface complexity is reduced while maintaining full functionality.
2Ease of operation
If separate virtual keyboard and virtual knob operators are used, then tone parameter control is achieved, but user experience is degraded due to the need to look away from keys to check parameter changes
Solution Approach 1:
The patent merges the parameter display and control functionality into the key interface itself. Visual feedback about tone parameter changes is provided directly at the key location, allowing users to monitor and adjust parameters without looking away from the keys, thus eliminating time loss and improving user experience.
3Adaptability or versatility
If sliding operation on keys is used to change tone parameters, then parameter adjustment is achieved, but interface complexity increases due to multiple operation types
Solution Approach 1:
The patent makes the key interface universal by enabling it to handle both sound triggering and parameter adjustment through the same basic interaction paradigm. The system detects different operation types (touch, slide) on the same keys and responds appropriately, providing versatile functionality without requiring users to learn separate control mechanisms.
Data Source
AI summary
A storage medium storing a musical performance program and a musical performance device are provided. A musical sound is output through a clicking operation performed on an operation button, and a tone parameter is changed through a dragging operation. A parameter display part 6a is displayed on the operation button. When the musical sound is output through a clicking operation performed on the operation button, a user can recognize a state of the tone parameter of the output musical sound in advance through the parameter display part. Since the tone parameter set through a dragging operation performed on the operation button is reflected to the parameter display part, the tone parameter is recognized without looking away from the operation button.
