Hi, I'm an independent sound designer and I've worked on several projects with other sound mixers already but all these projects had stereo soundtracks. I'm kind of a newbie when it come to surround mix. I can't do surround so I'd have to give my sound design to a mixer who would have the right equipment.
Let's imagine that the mixer works on pro tools and I work on Reaper. How does that work ? What do I give him in order for him to do a proper surround mix ?
