I find this program to be the scourge of the earth, yet for reasons beyond my control I have to use it. I hate that so many concepts have been reinvented (for the worse often, but at best just to be different and thus confusing). The whole destructive editing thing is quite good though, with all the undo layers PER file. That's the only thing I hope makes it to Logic. The program is riddled with bugs. For example, it switches to surround at random. And when it does, switching back to stereo doesn't fix the internal routing. One can't export the final stereo mix anymore (you just get silence). Crash crash crash (on 30 different machines). I don't know why Apple decided (after purchasing Emagic) to pursue this program. I've talked to various audio professionals who tried it and avoid it like the plague. I really did try to give it a chance (I started using it in depth August 2008), and at first thought it might be me (I know ProTools and Logic inside/out). But after figuring out a lot of stuff it just seems worse than ever. Was this program made by actual audio professionals who do actual work in the real world? Or was it all based on some theories of what ought to work? Even if there were zero bugs in this program I don't think it has a chance in the real world. Am I frustrated? Yes! I wouldn't be writing all this if I didn't absolutely HAVE to use it (there are plenty of things in this world I don't care for, but I'm not forced to use, so they can exist without my scorn).
