I feel you man. I've finally used Cubase enough to get proficiently fast at editing stuff, and I can't get it to work on Mint. It is quite the dilemma.
From what I've seen from Bitwig, I still might switch though. It looks a lot like Ableton, but I much prefer Bitwig's UI. And my most used plugins (arturia stuff) happens to run without any hassle on Wine (for now).
Still, I'll probably keep dual booting for a while. I have so many Cubase projects backed up that I don't feel like converting all to Bitwig projects.
