I see a lot of people going into a DI box, into their interface, out to their reamp box and then to the amp. Pretty much any youtube tutorial. They'll be using headphone monitors plugged into their DI box to hear what they are tracking. What I'm trying to figure out is how do they track in tempo if the DI Box is before their interface in their signal chain? youtube link i'm referencing:
