Open Settings menu > Modules >Remote tab.

Select the VTR Control plug-in and enable it.

Press Configure to specify the connection COM port and some VTR-specific settings. Click OK to apply.

Right-click somewhere on the playlist and select Add/Insert Event > Complex item > Custom Complex event.

Create a new complex event preset:

In the Beginning events list, insert a VTR event and a Matrix switcher event (optionally, you can insert graphics control events, too).

If there is an In and Out time code in the VTR control event, insert ending events as well (such as Matrix control and graphics control – logo, TitleBox net control events).

Click OK – a complex event line will appear in the playlist. AirBox will execute it at reaching this point in the playlist (taking into account the specified offsets, if any).

TIP (!) The created complex event will appear in the list of presets for later use: right-click in the playlist > Add/Insert Event > Complex item.
