@hemanthoj, You know I don't want to sound biased because I've never used it. I have always see parts of it and thought that it was sort of like Garageband, not super pro but good for people who what to just make music. The more hardcore programs that allow more manipulation, power, etc are what I prefer because of their flexibility on so many levels. Digital Performer is the most flexible sequencer for composing, especially through composing. Logic is okay, but DP beats it in my opinion. I may give logic a solid chance again sometime though. For mixing and mastering Pro Tools is definitely the one.
