Mouse Pressure

Use analog mouse-button force as Windows Ink pressure and tilt.

Download for Windows · Compatibility

The Logitech Superstrike has analog sensors in its left and right buttons. Logitech's software uses those sensors to adjust click actuation. Mouse Pressure uses them as continuous input.

Press lightly for low pen pressure. Press harder for more. Either button can also control X-tilt, giving drawing applications a second analog value.

Mouse Pressure sends standard Windows Ink input and does not install a kernel driver.

What it does

• Reads both analog mouse buttons independently
• Sends pressure, X-tilt, Y-tilt, or rotation through Windows Ink
• Calibrates light and full presses for each button
• Applies adjustable response curves
• Includes a small physics sandbox for testing analog input

Using both buttons

Both buttons can be mapped to different outputs, allowing you to control different continuous values at the same time.

Leave the left button mapped to Pressure and map the right button to X-tilt, Y-tilt, or Rotation. In Krita, those pen sensors can control hue, size, opacity, or rotation while the left button controls the stroke.

To configure it in Krita:

1. Open the Brush Editor with F5.
2. Select the brush property you want to control.
3. Choose the matching tilt or rotation sensor.

Other Windows Ink applications may expose similar controls.

Games and experiments

Analog button force can control more than brushes. The driver includes a sandbox game (under the Mouse tab) that uses pressure to extend and retract a chain.

Developers can use the Windows Ink inputs in their own pressure-sensitive mouse games. A Godot plugin is planned to make those signals easier to use.

Install

1. Download MousePressure-<version>-Setup.exe from Releases.
2. Run the installer.
3. Connect a compatible mouse.
4. Open Mouse Pressure and select Start.
5. Choose a pressure-sensitive brush in your drawing application.

Photoshop uses Windows Ink by default.

For Krita:

1. Open Settings → Configure Krita → Tablet Settings.
2. Select Windows 8+ Pointer Input.
3. Restart Krita.

Use Ctrl+F12 to start output. Use Ctrl+Shift+F12 to force-stop it.

See compatibility for supported hardware and applications.

Alpha limitations

This is alpha software.

• Tested on Windows 10
• Windows 11 expected to work but not yet verified on physical hardware
• Unsigned installer may trigger Microsoft Defender SmartScreen
• First stroke after starting can occasionally appear as a dot
• Pressure behavior varies between applications and brush presets

See compatibility for the full support scope.
