Me and some buddies are working on a project or two. They have Cakewalk and I have Logic. If I send them all the audio files and stuff...could they open it up in Cakewalk...
I don't know why your title said protools but your question didn't say anything about it...
You won't be able to open the session in protools.. but you can render all of the audio tracks to the same starting point, and then take those files into protools ... (thats the easiest way)...
And the same principle will work for other DAWs ...
I like what zygo said. bouce everything down to tracks and then export them. only question now is...when you export it does it export it track by track...meaning that when they open it they will have to open each track up into a new track individually or does he just have to open one file that will open all the tracks up?
If you're looking at working collaboratively with this person alot, you should look into both building your systems to be more compatible [i.e. use the same software + plugins] and keep your sample libraries up to date with each other... copyright permitting of course.
