That's a drag and definitely not good for pro users. I love so much about X2 and Cakewalk in general but I just don't know if I'd be able to have a pro studio based solely on it. I'd probably keep a backup program around just in case I hit a wall and I see a lot of our big studio forum members keep multiple DAWs on hand. I'm starting to think I should pick up Reaper in hopes that the things I can't accomplish with reasonable ease in Sonar can be done there. I definitely don't want to have to learn a whole new platform though and last time I installed the demo it confused the heck out of me. Would probably make a little more sense now that I've got some general knowledge on DAWs though.
But I truly adore X2. I just wish ALL aspects of it would work reliably... or at least the features I need to use. That however is an ever expanding list.
Word!
This is the second real issue I have had with X1 or X2. The first being M-Audios fault with shoddy drivers so I had to buy a second sound card to work in a stable fashion with Sonar, this has turned out to be a blessing in disguise as the Delta 1010 works flawlessly with Pro Tools so I have a backup DAW and Card if things go wrong in Sonar. Essentially like having 2 studios in one box (I can even have Sonar and PT running at the same time which I never thought would work!)
Like you, I adore Sonar, I have been using it since 1997 (well Cakewalk Pro Audio back then) and I have zero desire to change, I just wish they would think of us Sound in Film guys when they dev.
