Logic Pro sharing a file to collaborate with
I want to collaborate on a Logic Pro project with a friend. The idea is that he works on a section, then I work on a section and so forth.
I've tried Dropbox, but it seems that Logic or the .lpx file isn't transferred. My next guess would be a shared folder in iCloud. However, I'm unable to see his updates after he submits them.
Any idea(s) of another solution? Or am I missing something obvious?
Thanks.
