The Selector object is found in the virtual view, under the Matrices section of the audio processing objects.

The Selector object is a source selector by default that has 8 inputs and 1 output.

In the factory panel, each output is listed on the right and the drop-down on the left is used to select between the various inputs coming into the Selector object. Notice that the output name on the object block will change to reflect whatever input is selected.

At the top of the factory panel, the object label name is displayed in the top-left corner.

In the right-hand corner is the lock button.

When the lock button is red, the sliders and parameters on this control panel are locked and cannot be changed.

This button next to the lock button is the Selection Mode switch. Turning Selection Mode on allows for the selection of various parameters for copying to a custom panel.

In the PROPERTIES pane, each object is given a default name based on the order it was placed on the workspace. This name will appear above the object in the workspace. The name can be changed to reflect the function within the design for enhanced clarity.

The name and type displayed above the object in the workspace can also be hidden by unchecking these Show checkboxes.

Coordinates, is showing where in the workspace this object is, and Size is the object box size in the workspace. These can also be changed by dragging the object around in the workspace or grabbing the handles to resize.

Allocation identifies the DSP in the system where this processing object resides. With multiple DSPs, you can choose the DSP where this processing will occur.

Under the OPTIONS section, we can change the number of channels on the object block. The Selector has properties for the number of inputs and outputs the object has. Each Output can select any one of the Inputs. The value can be typed directly in. Inputs have a range from 2 to 512. Outputs have a range from 1​ to 512.​

Enabling Stereo, will change the inputs and outputs to stereo, treating them as pairs that will also be reflected in the drop-down selection.

Allow None is on by default and will make None a selectable input choice, resulting in no audio passing to the output.

Use Signal Names is also on by default. This will show the input names under the drop-down list. Turning it off will switch the input names to their respective input numbers.

Finally, the mode of the Selector object can be changed from Source Selection to Destination Selection. This mode changes the matrix to have one output destination per one input source. An example of this could be an application with 4 meeting rooms and 4 wireless microphones. There might a need for each microphone to go to a single room at any given time.

This matrix now in Destination Mode shows the microphone inputs on the left side and the selection drop-down now on the right to designate which output, or room, each microphone will go to.
