Setup tab Global

Usine's global setup tab. Various interface layouts and performances options.

import old setup

Imports all the settings from a previous Usine's installation. Click the button and select the folder (Win) or the .app (MAC) of the previous version.

This will copy the /Config/ folder of the old Usine to the new installation, including Snapshots, Devices, Addons, Browser Favorites, Plug-ins, Templates, Trash, Recent workspaces.

Note: Requires a restart of Usine to apply the change.

global Interface

main language

Sets the language Usine is displayed in, English or French.

color Style

Color style of Usine.

global zoom scale

Allows the adjustment of zoom for the entire Usine interface. Note: Useful to adjust the interface size on tablets.


Various tweaking options of the engine.

hardware acceleration

Turns on the hardware graphic acceleration for the GUI of Usine. Sometime the graphic card can de in conflict with sound card drivers.

  • no acceleration : all graphics are calculated by the CPU. Slower but safe.
  • direct 2D : all graphics are calculated by the GPU using the Windows Direct2D layer.
  • skia : all graphics are calculated by the GPU using the skia 2D layer. See
  • 3D GPU : all graphics are calculated by the GPU using the Windows DirectX layer. Fonts can be aliased.

It may seem counter-intuitive, but for video projects it is better to disable hardware acceleration in order to give the video engine full access to the graphics card, and not share it with the Usine interface.

buffered drawing

Usine will use a 2 steps buffering for drawing. This improves the graphic performances, but decrease the render quality especially when controls are zoomed.

fast text canvas

Try to draw text faster, but takes more memory.

graphic quality

Option to choose the graphic quality to increase the global performance. Low graphic quality can reduce significantly CPU load, but also reduces graphic precision.

refresh speed

Sets the global Usine refresh speed. For low value (5 ms) Usine is very reactive and the graphic display looks smooth but cost more CPU. Note: 25 ms is a good value in most situations.

max number of threads

Determines the maximum number of threads allowed in Usine. Note: Each rack is processed in a separate thread.

max number of sub threads

Some heavy modules and sub-patch calculation are split into several sub-threads. This Number of sub-threads max allowed, you can increase it if your CPU has a lot of cores.

disk buffer size

Disk Buffer Size of the reading audio file buffer. Note: A good value is around 2000ms. Increase if you use large multi-channels files.

CPU load max

Sets the CPU protection level. If the CPU Load is greater than the CPU maximum level, the process engine stops for few seconds, to avoid hard crash of your system. Note: Generally 90% is a good value modern processor. Note: If you want to disable this protection set the value to 100%.

draw in the background thread

Ask Usine to refresh the GUI as often as possible, but always in the background. Increase fluidity at the expense of CPU consumption.

floating windows

Switch the selected windows into floating mode.

floating window for patches

Switch the patch-editor-panel into a floating window.

floating window for settings

Switch the settings-panel into a floating window.

settings window height

Height of the settings window in percent of the screen height. Note: Only if floating window for settings is activated

floating window for grid

Switch the grid-panel into a floating window.

floating window for popups

Switch the panel-popup into a floating window.
