I'm asking because this feature is enabled by default, and I wonder if it should be kept like that. More details:

If it's enabled, every copy of midi region is linked and you can unlink it.
I don't know if it can be done the other way around .
@unfa
@rghvdberg @snailerotica It can't. There's noway to choose to link regions or duplicate them linked. It's either all or nothing.
