CEP is indeed the best recording/mixing software program for audio files. not only it has a very very easy to use interface and everything at one mouse click (or two keys combination) away, but also has that wonderful feature of keeping your work, even if the system is crashing.
and is true, like someone said before, if the CEP crash, most likely is the hardware configuration the one to blame, i know because this was my case too!
i've heard about some other professional sowtware for rec/mix, even tried out some trial versions, but i tell you, the CEP is two or three steps ahead everything else.
go for it!
