Don't have much time to report, but it just kinda, sorta works. All X3 projects opened without issues.
Control Bar improvements are great.
Updated FX Bins/Sends - probably good for touch users, but nothing out of the ordinary
VocalSync, updated AudioSnap - haven't had a chance to try properly yet
Mix Recall will definitely use soon on a real project if I manage to make it work - right now it's greyed out for some reason. It wasn't yesterday. Probably will report it right now even though the website still talks about Producer everywhere.
Downloads indeed went fine. The need to install sub-products one by one if you want to skip the loops is really a pain. The products rescan and update check after every operation is even more annoying. Command Center also crashes every time I click on my account name. So... it's you know... there... the public beta :)
