MetaGrid Pro Selected Channel — Mac port-detection test

This test script starts from the MetaServer 6.1.6 bundled Selected Channel 1.1.5 script. Its only functional change is an additional detection pair for the Mac Cubase Sync - In and - Out ports. It retains the 1.1.5 editor-window feedback bindings. Version 1.1.5.1 is a test label, not a released MetaServer update or a confirmed fix.

1. While Cubase is open, check MIDI Remote Manager > Scripts > Script Info for the MetaGrid Pro / Selected Channel script path. If it is not the path below, or your installed script is customized, tell us before replacing anything.
2. Quit Cubase completely.
3. Make a copy of the current script outside the Cubase Driver Scripts folder so you can restore it.
4. Replace this file with the attached test file of the same name:
   ~/Documents/Steinberg/Cubase/MIDI Remote/Driver Scripts/Local/MetaGrid Pro/Selected Channel/MetaGrid Pro_Selected Channel.js
5. Start MetaServer, then Cubase. Check whether Selected Channel appears and uses Metasystem - Cubase Sync - In and Metasystem - Cubase Sync - Out. Do not add it manually yet if it is absent; first note what MIDI Remote Manager shows.
6. Quit and reopen Cubase twice with MetaServer still running. Tell us whether Selected Channel appears and remains connected after each launch. A screenshot of MIDI Remote Manager after a failed launch would help.

Do not run MetaServer's Install/Update/Reinstall script action during this test; it may replace the test file with the bundled copy. If the test causes trouble, quit Cubase and restore your saved original script. This test concerns surface detection; it does not by itself fix latching feedback or Plugin Manager behavior.
