The Recording Light control surface plug-in enables you to control an external light or sign, warning visitors not to enter the recording studio before or during recording. Logic Pro sends a MIDI signal to switch on the external device when a track is record-enabled or when recording starts. Logic Pro sends another MIDI signal to switch off the device when tracks are made record-safe or when recording stops.

Note: This control surface plug-in requires additional hardware that is not included with Logic Pro.
