I used to use Cakewalk pro audio 8 (or 7, Im not sure) . It seems to me that N-track does everything Cakewalk does and for a much cheaper price. It even has more things, like you can use vst effects (which I like better than directx effects cause their easier to "install") Exporting to a mp3 and some other formats. You can also have similanious tracks coming in at once (multi input soundcards. I think n-tracks easier to use, even though I had a little trouble ajusting to n-track because differences in shortcuts etc. The manual for n-track is very good and explains things in a way that you can start working right away. I suggest that you get n-track. It may not have as big a name as Sonar, but because its easiness, low price tag, and features that you ussually only get in "pro" versions of software. Thats my opinion, but you should probably ask people who like Cakewalk too, since my opinion will be biased since this is the n-track forum.
