X2a working very well here.
I love the improvements in workflow. Auto Track Zoom is excellent (sorry, Beep). The timeline zoom etc. is great. Love the improvements in the PRV. I love Automation Lanes and Take Lanes.
I really like the Console Emulation. And Breverb - it's become my "goto" reverb. I've not really used RMix, but can see its usefulness. I wasn't that keen on TH2, but have used it on my latest track a few times and am starting to like it.
The audio engine is so much smoother. I fiddle around as the track is playing and there are no glitches.
There are loads of other improvements, but these are just off the top of my head. I'll post any more if they occur to me.
It took me a wile to get used to X1 (coming from Sonar 6), but by the time X1d came out it was rock solid, and so much of an improvement. X2 was a
little crash prone at first, but the quickfix, and especially X2a have made it rock solid again.
I love X2. I'm working much faster, and getting much better results.
Thanks for starting the thread, Beep.
