Watch all six MIDI links from the checklist, including ProPresenter -> Lighting
Adds Tracks -> Livebox, Tracks -> Studio B and ProPresenter -> Lighting
(read on the ProPresenter Mac over SSH), each with the hold-to-reconnect fix.
coremidi.py now recognises the network MIDI driver on macOS 26.2 too
("AppleMIDIRTPDriver"; 26.5 calls it "AppleMIDINetworkDriver"), which is why
the ProPresenter Mac's session looked empty before.

NA Ingest's own session is read locally; NA Tracks' and NA ProP's over SSH every 5 s. Also: the Lighting PC and NA Tracks MIDI sessions still announced on the network. A clean disconnect shows within about 10 s; a crash or pulled cable takes about a minute (macOS's own timeout, measured). Hold 2 s reconnects whichever links dropped. |
