I've had the most frustrating night working with Sonar. Bugs, crashes, wrestling with temperamental automation nodes. But most of all the crashes. I've had crashes galore tonight, just doing the most innocuous things like drawing in automation or moving a clip. I ditched Pro Tools because of the frequency with which its audio engine crashed (and 32-bit....pah). But with Sonar, I don't even have to be playing music back for it to crash. It happens when I'm clicking around in the track view, or more often, clicking around in the console and in ProChannels.
I'm really hanging in there for an update to fix some of these problems. Because quite frankly I'm not managing to be that productive with X2. I spend half my evening trying to get to the bottom of quirks and bugs and restarting after crashes.
Sorry to be so negative, but there it is
