As it stands, the crashing in Sonar X2 is to the point I'm trying out Presonus Studio One.
I have to say it is not nearly as nice a piece of software, workflow wise. I see what they were going for with simplifying the workflow but in their effort to do that I think they've made things more difficult, particularly with regards to various MIDI things. I really prefer Sonar's workflow.
However what I do have to give them credit for is a stable engine. It seems to just run, no problems. I haven't gotten it to blow up yet at all. Sonar likes to blow up for all sorts of reasons. The Piano Roll is a big one, and I can't figure out why. It isn't universal, but it happens a lot, and the error is a data execution prevention error which you shouldn't see in this day and age. It also likes to blow up when I insert Play occasionally for some reason, and that is my most used VI.
There really needs to be a better focus on stability, process isolation, and so on, not just on features. A DAW isn't very useful if it blows up all the time and I'm not asking it to do difficult things. Something like "load a VST instrument" shouldn't cause it to blow up. Even in the event there is a problem, it should be able to recover.
Particularly since Studio One seems to be able to run stable.
