Greetings
I want to clear an unused  patch point from Platinum. There are no inputs or outputs connected to this patch point, but it still remains as a send after closing and opening the project. Am I missing something?
Thanks

You may need to re-check all tracks (including hidden ones) and buses. It's most likely something still has that PP assigned as an input, output or send target. I've not seen a completely 'orphaned' patch point persist.

This is where an aux track/patch point routing diagram would be handy.....

you may need to close and reopen the project, in my experience
