Mixer Parameter Fading with Independent Start Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital mixing systems require multiple scene data to achieve complex parameter variations, leading to increased complexity in management and memory requirements, as all operator members start changing simultaneously upon scene recall, making it impossible to control sequential fading of faders with a single scene data.
Innovation Solution
A parameter control method using non-linear functions to independently vary parameter settings for each operator member, allowing for diversified and complex parameter changes in response to a single automatic setting instruction, along with the option to delay event processing based on set start delay times.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple scene data are created to achieve sequential fading of faders, then complex parameter variations can be achieved, but the number of scenes increases greatly and management becomes complicated
Solution Approach 1:
The patent introduces dynamic control of parameter changes by allowing different fade times to be set for each parameter. This enables a single scene data to dynamically control the timing and sequence of parameter changes, replacing the need for multiple static scene data. The fade time parameter allows each parameter to change at its own rate, creating sequential or simultaneous changes as needed.
Solution Approach 2:
The patent changes the approach from changing scene data to changing parameter values within a single scene. By introducing fade time as a controllable parameter for each parameter change, the system can achieve complex variations through parameter adjustment rather than through multiple scene data structures. This single scene data with multiple parameters includes start delay times and fade times for controlling the timing of each parameter change.
2Productivity
If all operator members start changing simultaneously upon scene recall, then simple scene recall processing is achieved, but it is impossible to control sequential fading of faders
Solution Approach 1:
The patent applies preliminary action by pre-setting start delay times and fade times for each parameter in the scene data. When scene recall is executed, these pre-configured timing parameters automatically control the sequence of parameter changes. The start delay time determines when each parameter begins to change, and the fade time determines how long the change takes, enabling sequential control without complex processing.
3Device complexity
If a single scene data is used for parameter setting, then management is simplified, but it cannot express complicated variation of parameters with different timing characteristics
Solution Approach 1:
The patent segments the control of parameter changes by assigning individual start delay times and fade times to each parameter. This segmentation allows each parameter to be independently controlled in terms of timing, enabling complicated variations within a single scene data structure. The scene data is divided into multiple parameter control entries, each with its own timing characteristics.

AI summary
Non-linear functions to be used for automatically varying current values of parameters to be set, independently of each other, are prepared in corresponding relation to a plurality of parameter setting operator members, such as faders of a mixer. In response to an automatic setting instruction, such as a scene recall instruction, the current value of the parameter, to be set via each of the operator members, is caused to vary gradually toward a given target value with a characteristic based on a corresponding one of the non-linear functions. For example, the non-linear function is defined by a start offset for setting a delay in a start of the variation, and a fade time necessary for actually causing the parameter to vary up to the target value after the variation start. Processing of a predetermined type of event (e.g., GPI event) may be delayed to allow for a time delay that would result during execution of automatic setting processing of each parameter.
