Sonar has some good improvements over Pro Audio 9. I have tried a few of the others, Cubase, Samplitude, Etc., but I truly like Sonar better. Probably because I have used it the most, and I am used to it. However, when I bought Sonar XL, I felt the same way I did when I upgraded to Pro Audio 9 from 8. I felt like I got screwed with the almost useless 2nd CD you get. I don't know what they pay their Marketing guy, but they need to give him a raise. He damn sure did his job. On the web site they told you all the great stuff about Sonar, but left out the fact that you have to have a Pentium 50 for it all to work. Anyway, I realize that all these programs have their quircks, and you can point out something bad about any one of them. Over all, I like Sonar. I just wish thsy wouldn't stretch the truth like they do.
