### Using the Matrix

* The matrix allows for **many-to-many mappings**, meaning multiple beams can be routed to the same audio input, and multiple audio inputs can be routed to the same beam.
* **All beams must be routed** before a preset can be exported. If routings are missing, you will see that the Preset status is incomplete and a warning will be displayed when trying to export.

### Adjusting the Number of Audio Inputs

* To adjust the number of audio inputs:
  1. Click on the **edit** icon in the properties panel.
  2. Enter the desired number of inputs.
  3. Press **Enter** to apply the change.
