SincKeyboardControl is a lightweight, proof-of-concept Windows application specifically built to interact with custom QMK (Quantum Mechanical Keyboard) firmware functions on the Keebio Sinc split keyboard.
Developed by GitHub user @ionothanus, the tool sits in the Windows system tray and utilizes raw Human Interface Device (HID) reports to allow direct communication between the Windows operating system and the hardware controller of the keyboard. Core Functionality
Raw HID Communication: It bypasses standard keyboard input streams, using raw HID packets to send specific commands directly to the keyboard micro-controller.
QMK Integration: It links directly with custom-coded functions written into the keyboard’s QMK firmware.
System Tray Convenience: It runs quietly in the background on Windows, allowing users to execute or monitor custom layout profiles and macro behaviors on the fly. What is the Keebio Sinc?
To understand the utility of the control software, it helps to understand the hardware:
75% Split Layout: The Sinc is an ergonomic keyboard split into two distinct halves, featuring a dedicated function row, arrow keys, and a macro column on the left.
Rotary Encoder Support: The board supports up to three rotary encoders (knobs), which are highly customizable for volume, scrolling, or scrubbing through timelines.
Highly Programmable: Because it runs on QMK, every single key, layer, and encoder behavior can be reprogrammed at the source code level. Why Use a Dedicated Control App?
While standard QMK keyboards use tools like VIA or VIAL for on-the-fly remapping, a dedicated tool like SincKeyboardControl is typically created to bridge the gap between host system states and keyboard states. This allows for advanced integrations, such as:
Dynamic Lighting: Changing keyboard LED behavior based on specific Windows notifications, active applications, or mute states.
Advanced Macros: Executing complex Windows command-line scripts or software-level shortcuts that standard hardware-side macros cannot handle alone.
Layer Tracking: Communicating back to the PC which layer is currently active so a software overlay can display it on the screen.
If you are looking to deploy this for your own setup, you will need to clone the repository from GitHub and ensure your Keebio Sinc firmware has been compiled with matching raw HID features enabled.
Are you planning to build or program a Keebio Sinc yourself? I can walk you through how custom QMK firmware handles raw HID reports if you want to modify the code.
