From the File menu in the application toolbar, click New: This action clears the Halogen Workspace so you can begin creating your new configuration. Don't worry about losing data, however.

When you click New, Halogen displays a window that lists the available HAL models and lets you choose one for your configuration:

Another way to choose a HAL model and begin a new configuration is to click on the dropdown arrow just to the right of the New button:
tip: Halogen includes a set of example configurations that you can use to start your configuration. These starter configurations include several audio applications, and you can access them in the New dropdown menu as shown above. (See Choose Starter Configuration)

In the New dropdown, click on Show Discontinued Devices to view discontinued models. In the model picker, check the Show discontinued devices when creating new configurations checkbox.
