Update #6 ; 09/05/26

Installation
• Cue2Live now installs its own Ableton Remote Script. On launch it copies the script into Live's User Library and keeps it in step with the app, so updating Cue2Live updates the script. No more copying .py files by hand, and no more app and script running different versions without saying so.
• Asks once where Live's User Library is if you have relocated it, and remembers the answer.
• Now distributed as a .dmg with an /Applications shortcut.

Connectivity
• Removed the port field. The Remote Script asks macOS for a free port and publishes it; the app and the iOS Bridge read that on every connection attempt. Nothing to configure, no clash between two rigs on one machine, and a Live restart is picked up without touching anything.
• Ableton's socket is now bound to loopback rather than 0.0.0.0. iPads reach Live through the iOS Bridge, so the backend is no longer reachable from the network.
• Moved the published port file out of ~/Documents, which prompted for Documents access on first run, into ~/Library/Application Support/Cue2Live.

MIDI Map Window
• Rebuilt. Even cells, mappings shown as a note name over its qualifier (D#2 above Note - CH 10) rather than a raw identifier, and unmapped slots that read as empty instead of carrying the weight of a real assignment.
• Added a line stating the pick-then-play model, which nothing in the window previously explained.
• Clear All resets all four transports in a single message, so the window no longer clears and briefly repopulates before settling. Apply is the default button, so Return commits.

Bug Fixes
• Fixed the MIDI mapping lifecycle: assignments did not take effect until some unrelated event happened to trigger a rebuild, removed mappings kept firing, and re-learning a pad left the old binding live alongside the new one. Live is now asked to rebuild after every assign and remove.
• Fixed Clear All leaving most mappings on screen in Cue2Live after removing them in Live and on iOS.
• Mapping changes are pushed to connected iOS clients as they happen, rather than the iPad showing a stale map until it reconnects.
• A bad mapping in preferences is now repaired and rewritten instead of stopping the Control Surface from loading.
• Two transports can no longer be left on the same MIDI message. Live's forwarding keeps only the last one, silently, so the second assignment is now refused.
• Backend socket server: broken clients are dropped correctly.

iOS Bridge 1.3 (bundled)
• Publishes a virtual MIDI port named Cue2Live and emits the iPad's MIDI on it. This replaces the RTP MIDI path used by iOS 1.x, which could not address one machine without the other hearing it.
• New MIDI Thru submenu merges hardware MIDI inputs onto that same port, so a tech's controller can drive the transport mappings the remote script listens for.
• New Port row in the menu for manual iPad connections, and the Bridge falls back to a free port when the configured one is taken.
