I say this as a primarily Linux user who also does music production on Windows, but anyone looking for a great DAW on Linux check out Bitwig. I found it really easy to use and well-designed. I’ve done a ton of music production on it and it works great. The only reason I prefer windows is because there are more compatible plug-ins.
I think I must have pirated Bitwig because I definitely haven’t paid for anything. That said, I don’t really use it much anymore. I’ve been trying Ableton and don’t mind it.
