With all this talk about X2B, as a new (active) user, I assumed that X2a must have been:
a) some time in the distant past; and
b) a pile of crap
I just went back to the announcement. That was only 6 freaking months ago, people, and it was loaded with enhancements as well as bug fixes.
You guys don't know how good you have it. Many software products get a lot worse treatment than that. One of the realities of software development is that complexity forces larger and larger test cycles. It is one thing to put out a simple website or mobile app and call it bug free -- or to put out rapid patches if bugs are reported. That maintenance model is not sustainable as the project complexity increases. And I would say SONAR is one of the most complex programs in any software category by now. With something like that, it really is not wise to slop out a patch a day. That approach will inevitably result in a maintenance nightmare.
While this "woe is me" thread was laboring along, I did a small Sonar project to continue up the learning curve. It was an accompaniment for a set of etudes. I had the piano track on MIDI already. I added French horn, flute, and string bass parts, did some nice effects, used the tempo tool to add rubato, rit and fermatas where indicated in the score, automated the mix to match the printed dynamics, and then did an editing cycle in the MIDI editor to clean up some conflicts with the solo voice. Everything worked perfectly and I couldn't be happier with the finished product. My guess is my experience is more typical than the stories on this thread.
The only bug I encountered is that at one point, the tempo tool stopped allowing me to make changes on every beat. So I did have to shut down Sonar and start it up again to clear that. And that is typical of the other bugs I have experienced. None of them have been very severe in my experience.
