Yeah, very informative, answered most of my questions in the affirmative. One thing kind of disappointing (although I may have misunderstood, he went through it kind of fast), it doesn't look like the piano roll editor has any place to actually manage what tracks are being displayed/edited. He said it displays whatever is selected in the track view, which would mean you have to switch views to select different tracks to edit? Yeesh, I hope I missed something. The PRV improvements like filter sets are pretty recent in Sonar but really useful.
The issue here is whether I can actually afford the crossgrade offer while it's active. I've noted I'm not really anxious to leave Sonar, but if I'm going to learn something new, I may as well get started. I just can't break my budget to do it. We'll see what happens, I guess.
