Operating Instructions
Customizing LCD Keys
The core functionality of the Stream Controller lies in its customizable LCD keys. Use the Control Deck software to assign actions and personalize button icons:
- Open the SOOMFON Control Deck software on your computer.
- The software interface will display a virtual representation of your Stream Controller.
- To assign an action, drag and drop a desired action (e.g., launch application, mute audio, open website) from the software's action library onto a virtual button.
- To customize the button's icon, click on the virtual button and select the option to upload a custom image file (recommended size: 126x126 pixels or larger).
- You can also create folders within the software to organize multiple actions under a single button, effectively creating a multi-layer virtual keyboard.

Creating Multi-Actions and Profiles
The Stream Controller supports complex multi-actions and profiles to further enhance efficiency:
- Multi-Actions: Combine several actions into a single button press. For example, one button can simultaneously launch OBS, open your streaming software, and send a "going live" tweet.
- Profiles: Create different profiles for various applications or workflows. For instance, you can have a "Streaming Profile" with OBS controls, a "Video Editing Profile" with shortcuts for your editing software, and a "Gaming Profile" for in-game commands. The software can automatically switch profiles when you open a specific application.
