Analog Sound Effects Control With Preset Memory and Remote Recall

The patent replaces manual mechanical adjustment of potentiometers with digital control systems. A microcontroller reads the positions of physical potentiometers and digitally stores/recalls their settings, eliminating the need for manual re-adjustment while preserving the analogue sound processing. This substitution enables memory storage and remote control capabilities without adding complex mechanical components.

The patent introduces a digital intermediary layer between the physical potentiometers and the analogue sound processing circuitry. This intermediary consists of analog-to-digital converters, a microcontroller with memory, and communication interfaces that mediate between the user's manual adjustments and the sound processing, enabling storage and recall functions while keeping the analogue processing path intact.

The patent segments the device into distinct functional domains: the control domain (digital, handling memory and remote control) and the processing domain (analogue, handling sound processing). The digital control system manages settings storage and retrieval, while the analogue circuitry maintains authentic sound processing. This segmentation allows each domain to excel at its specific function without compromising the other.

The patent uses digital-to-analogue converters as intermediaries to bridge the digital control system and the analogue sound processing circuitry. The microcontroller stores and recalls digital representations of potentiometer positions, then outputs control signals that adjust the physical potentiometers or directly control analogue switches, ensuring the sound processing remains purely analogue while benefiting from digital memory capabilities.

The patent implements a single control button that performs multiple functions: storing current settings to memory, recalling stored settings, and potentially selecting between different memory locations. The button's behavior changes based on the device's current state, as managed by the microcontroller. This multi-functional approach provides enhanced control capabilities while maintaining a simple, intuitive interface that resembles traditional analogue devices.

The patent incorporates feedback mechanisms to inform users of the button's current function and the device's state. LED indicators or display elements provide visual feedback about which memory location is active, whether settings are being stored or recalled, and the current operational mode. This feedback ensures users understand the button's next action without adding physical complexity to the interface.
