Block Reference



Use the Selector block to choose one of several possible audio signals. Selecting an input channel sends that channel’s audio to the Selector block’s output.

How to Use

The Selector block is useful for selecting from a number of background music channels or record channels.

Adding the Block to Your System
  1. Click the Processing tab to open the Processing Workspace.
  2. In the palette area, click the DSP tab.
  3. Expand the Selectors category of blocks.
  4. Click and drag the Selector block into your Processing Map.
  5. Wire it into your system in the appropriate location. If you need additional inputs, simply wire to the <Add> node or click the <Add> text.
  6. (Optional) Customize the name of the block and/or its Input node(s) and Output node by clicking the current name and then typing a custom name in the text box that appears. Click the X to save the name.
Configuring the Block
  • Open the Selector block's properties by double-clicking the block or hovering and clicking the properties icon that appears in the upper right of the block's title bar. From here you can do the following:
  • Manually select an input channel by clicking it, which then sends that channel's audio to the block's output.
  • Provide end user control over the input selection by linking the block's selector control to a DR2 or DR3 selector control. When active in a link, the display names for the input channels appear next to the block's input channel names.
  • note: A DR selector is limited to a maximum of 20 selections. This means that to link a DR selector to a selector block, the total number of inputs must be 20 or less and when linked, the selector block can have a maximum of 20 inputs.
