Well, it does seem to work ok on my old MacBook Pro - even just with the built-in audio interface. Should be fine with the Focusrite. And with 64 tracks available, I could probably load all my old projects as I don't think I ever used more than 40 in the most extreme cases back in the days.
It's nice to finally get a glimpse at the redesigned interface and to get re-aquainted with a few old favorites, such as the Sonitus Suite.
In a way, I'm almost happy that they cancelled it as I didn't want to upgrade the OS on my DAW and I would have had to in order to run it. The laptop will do the trick for this.
So... Thank you Cakewalk.
