IMPORTANT: Run the Switch Calibration Tool

Any mechanical switches you install in your GMMK 3 HE keyboard will not register an input until you download Glorious CORE 2.1 and run the switch calibration tool. 

  1. Download and run Glorious CORE 2.1

  2. Make sure your GMMK 3 HE keyboard is plugged in.

  3. Click on the keyboard when it appears on the home screen.

  4. Click the “Performance” tab.

  5. Run the Calibration Tool and follow the on-screen instructions.

If you decide to swap switches down the line, mechanical switches (MX) will require this process to function. We recommend this process for magnetic (HE) switches to ensure peak performance with HE features.

Using the Rotary Knob

  • Rotating the knob clockwise raises your device’s volume.

  • Rotating counterclockwise lowers volume. 

  • Pressing the knob once toggles between muting and unmuting your device’s sound.

  • Double-tapping the knob cycles through the keyboard’s 3 customizable layers.

Customizing Functions: The knob’s functions and keyboard’s layers are customizable via Glorious CORE 2.1.


Switching Between Windows & macOS Functions

On the backside of the GMMK 3 HE near the USB port is an Operating System Toggle Switch that lets you instantly change the keyboard’s bottom row functions to match either Windows or macOS. 

  • For Windows (Default): Flip the switch to the left, and the device will use the bottom row inputs that match the standard Windows layout.

  • For macOS: Flip the switch to the right, and the device will use the bottom row inputs that match the standard macOS layout.


Switching Between Keyboard Profiles

3 custom profiles can be saved to the GMMK 3 HE. On the backside of the board, near the USB port, is a Profile Switch with three positions. Each corresponds to the respective profile they activate.

  • For Profile 1 (Default): Flip the switch to the far left position.

  • For Profile 2: Flip the switch to the middle position.

  • For Profile 3: Flip the switch to the far right position.

Customizing Profiles: Profiles can be customized via Glorious CORE 2.1.
