When do I need a World Clock?

[Tamate]

Hello guys, when do I need to add an external clock to my rig?

Thanks!

You mean Word Clock.

Unless you're connecting a bunch of digital interfaces....I wouldn't worry about it.
A single digital interface can be set for internal clock from the DAW computer,

True. I use a GenX6 to sync all my digital stuff.
