dangars - if you're recording to get your own ideas expressed sure learning Studio is great.
But if you're already comparing your ear to someone who is whipping up things in another DAW and they are paying for expensive training - if your tastes lean toward that caliber of recording you'd do yourself a great favor early on by upgrading to Sonar X2 Producer. Train on that and you'll be golden.
Scott's book is a welcome reference that covers it all. I learned the most quickly by the many video tutorials available. Many are free on the Cakewalk site, and there are excellent ones in the store. I have them all. The more training, the better you realize what's possible and how to get there fast.
