Spent the morning working in x3 (finally, after 3 months of getting it up and running) - did some voiceover work, with an midi incidental instrumental. Then a jingle with vocals and midi instrumental.
My impression: I'm blown away. Very fast to work in. And the audio quality of the results is out of this world!
It's taken a long time to get there. But is it worth it? Yes.
I will not be using sonar 8.5 again.
