interesting... i should get into protools asap to make up for my lack of talent. haha.
just found out, digidesign owns sibelus na pala. so may notation software na rin.
just remember that a good song and a good recording will show just that - good technique showcasing a good song. No amount of pro tools and studio tomfoolery will be able to fix a song that was recorded and written halfa$$ed. some people like to think that PT, just because it is the studio standard, will make you sound better. This is not true and a large misconception because, really, it is not just the arrow (PT) but the how well the indian makes use of his skills in shooting the arrow. Sonar, Cubase, Nuendo, PT and whatever else is out there are all tools and you shouldn't loose sight of the fact that they all basically do the same thing: record music. Things, however, get trickier when you start looking at the signal path.
I don't use wrappers a lot with PT except for specific plugs that just don't have RTAS versions available. Otherwise, I try and keep my plugs all RTAS to keep things simple. I figure, the less troubleshooting I do, the more work I get done.
