Macro Pages
HALion allows you to build your own sample and synthesizer instruments and to customize them using the integrated Lua script engine. Via the Macro Page Designer, you can create your own user interface for these instruments.
Editing and Assembling Elements
For your macro pages, you will use many elements that need to be placed on the canvas in a specific order, have a specific color and size, etc. You have many possibilities for adding, editing, scaling, and arranging the available elements on the canvas.
Templates
You can create and arrange controls directly on the canvas and then connect them to HALion parameters. This is a very straightforward way of creating a macro page. However, with this workflow, once the page is set up, it becomes very difficult to change the look of some controls globally, because you have to edit every single instance of these controls on the page. Therefore, it is often better practice to work with templates.
Variable Export
You can export the value of a variable to create an interface that allows you to connect parameters outside of the template.

Variable Export

You can export the value of a variable to create an interface that allows you to connect parameters outside of the template.

For example, you can connect the menu switches of a pop-up menu to the selector control that opens the menu.
