Mouse and keyboard settings

The Zen stores one .zmk profile at a time, so Save to Device replaces the one already on it.

1. Connect the Zen's PROG port to your PC.
2. Open Zen Studio Live in Chrome, click Connect Device, pick Cronus Bridge and click Connect.
3. Open Mouse & Keyboard Settings.
4. Optional: click Import to start from a saved .zmk file.
5. Name your profile in the Profile field.
6. Pick the profile to edit: HIP, ADS or AUX 1 to AUX 4. Each AUX profile switches on with a key or mouse button you assign.
7. Choose PlayStation or Xbox button labels.
8. On the Primary and Secondary tabs, set a key or mouse button for each controller button. Press the input to capture it, or × to clear a row.
9. On the Movement tab, set the left stick keys (default W, A, S, D).
10. Set Walk Scale for how slowly you move while holding the WLK key (default G).
11. Set Analog Sim so W, A, S, D ramp up like a stick instead of jumping to full.
12. On the Controller tab, remap the sticks and triggers with the dropdowns and set a Deadzone for each.
13. Tune your aim under Aim Settings (list below).
14. Optional: shape the Ballistic Curve (list below).
15. Press Finalize, then Save to Device.
16. Optional: click Export to keep a copy of the .zmk file.

Aim settings

• Sensitivity: overall aim speed. Raise it to turn faster.
• X/Y Ratio: up and down speed as a share of left and right speed. 1.00 means both match.
• Boost: amplifies the stick output, so small mouse moves turn the aim further.
• Smoothness: blends recent mouse readings to remove shake. More smoothing is steadier but adds delay.
• Invert Y-Axis: flips up and down.
• Game Deadzone X and Y (under Translator): cancel out the game's stick deadzone so the slightest mouse movement still moves the aim.
• Game Deadzone Shape: set it to match the shape of the game's deadzone.
• Analog Stickize: a multiplier on the emulated stick output.

Ballistic curve

• The horizontal axis is mouse movement and the vertical axis is aim movement, both 0 to 10k.
• A straight line from corner to corner is linear, so the aim moves exactly as much as the mouse.
• Drag a point, or type its exact X and Y.
• Remove drops the selected point. The first and last points always stay.
• Reset returns the curve to linear.
