I'm glad your experience with Ubuntu Studio was positive! I don't know why you accused me of being disingenuous; I assure you I was not. Recording audio in was seamless, as you mentioned. Plugins were frequently unstable, however, and crashed my computer. It was hard to figure out what worked, and it was hard to find a decent convolution reverb that sounded as good as Space Designer. The only software I found that had easy timing adjustments was Tracktion, and that also crashed frequently. It was hard to use MIDI tracks side by side with audio, both because the interface of Ardour was confusing and because (shock) it crashed frequently when I tried to. And it took way too many steps to load an SFZ library. I certainly have problems with macOS too, but I really am desperate to leave Apple entirely, and I wish Linux worked for music for me.
