Versions:
Griffin PowerMate, published by AccolyteByte and currently at version 1.2.0 (the sole release available), is a Windows 11 driver and GUI application designed to bring new life to the Griffin PowerMate USB knob, a hardware controller that was discontinued in 2018. Falling into the hardware utilities and input device customization category, the software provides a fully customizable control layer for the knob, supporting every interaction the device can produce: rotating left and right, single, double, and triple presses, long presses, and pressing while rotating. Each of these interactions can be assigned rich action bindings, including volume adjustment, media playback control, mute toggling, keyboard shortcuts, macros, scrolling, and application launching. The application supports per-application profiles, allowing the knob to behave differently depending on which program is in focus, which makes it useful for tasks such as editing, media consumption, and general desktop navigation. Visual and system feedback features include full control over the knob's LED, a translucent on-screen display overlay that reflects knob activity, and a system tray icon for convenient access to the application. Typical use cases include repurposing the legacy PowerMate hardware as a modern desktop controller for audio mixing, timeline scrubbing in creative software, system volume management, or custom macro execution on Windows 11. Installation requires the WinUSB driver to be installed via Zadig, with further instructions provided in the project's README. Overall, Griffin PowerMate serves users who want to continue using the discontinued USB knob on current Windows systems, offering a comprehensive customization interface that maps its physical inputs to a wide range of software actions.
