Walk into most venues and the show is split across three machines and a
lot of trust. Sound on one, projection on another, lighting somewhere
else, and a person holding all of it together with a headset and good
timing. It works, right up until it doesn’t — and when it doesn’t, it
is always in front of an audience.
CueForge is the other approach: one cue list, every department in it, so
the cue you press is the cue that happens. Add a second Mac and the show
is genuinely redundant — not a copy of the file on a shelf, but a
machine already running the same show, one click from taking the room.
It is built natively for macOS rather than ported to it. Audio goes
through Core Audio, video is composited on the GPU with Metal, and the
application is written in Swift from the ground up. That is not a
marketing detail — it is why the clocks are steady, why a projector can
be re-calibrated while content is playing, and why the whole thing runs
on a laptop you can carry to the gig.
