I use Bias Peak 3.0 to record 2 track into my computer almost exclusively. I have not had any problems with it at all thus far and can't really see myself having any major problems in the future.
My only complaint is that in order to record to CD, you must export the entire file, with track markers, into a playlist that can only be burned by Toast Titanium. Not that I don't like Toast Titanium 5.0, but I wish I had other options if need be.
If you have any questions, feel free to pmail me directly.
