Video: A tutorial demonstrating the software customization options for the magnetic axis, including stroke settings and advanced key functions.
5.4.1. Actuation Settings
The software allows you to adjust the actuation point of individual keys. This is particularly useful for gaming, enabling faster response times.
- Comfort Mode (Factory Default): The key stroke is similar to a standard axis, triggered at around 2mm. This mode supports custom modification.
- Sensitive Mode: The key stroke is equivalent to a fast silver axis, with buttons triggering at 0.3mm. The travel values for quick trigger press (trigger) and release (reset) can be set separately.
5.4.2. Advanced Keys (DKS, MT, TGL)
The software provides advanced key functionalities:
- DKS (Dynamic Key Stroke): Supports up to 4 functions per button, allowing you to bind one to four functions based on different degrees of compression.
- MT (Mod-Tap): Enables two functions in a single key. One function is activated by tapping, and another by holding. You can set the hold duration (e.g., 1000ms).
- TGL (Toggle): Tapping the key once will continuously trigger it as if it's being held down, until it's pressed again to switch off.
