If there was no SONAR I would just book time at Abbey Road. Of course I would.
I'm not really sure what I would do. In the past I've tried Reaper, Cubase, Magix, Studio One and a few others I can't think of. I couldn't bond with any of them. If I actually had to pull the trigger I guess I'd give Studio One a whirl. Or maybe I'd just go back to my Fostex A-8.
