Any of these can drive the NOW / NEXT footer via HTTP GET or UDP (NOW:TEXT). No extra plugin.

Where the automation can read a desk GPI / fader / channel ON and fire HTTP GET or oas_send, LED1 (ON AIR) can follow the mixer. That is not the same as “this PC is the on-air studio”.

A desk dry contact into a Raspberry Pi is often shorter: User Manual (GPIO).

RadioBOSS, RadioDJ, StationPlaylist, and RCS Zetta have no documented mixer-tally → HTTP/UDP path that is solid enough for a howto. Use Pi GPIO, or send LED1:ON yourself if you already have a script.

The mixer sends Note or CC straight into OnAirScreen (Settings → GPIO → MIDI). No playout in between. The computer that runs OnAirScreen needs the USB cable.
