...is out this month!!! If you have any Cakewalk product you can get the Studio edition for $200 USD. That is 280 bucks off. If you have Sonar 3 it's a $100 upgrade.
If you were looking for a good DAW to record with, Sonar is a great program. It has excellent features and you'll likely not outgrow it any time soon. I have been using Cubase SX
, which, by the way, also has a new edition out this month, but I got an email from Cakewalk making it too irresistable to pass on. I own several Cakewalk products, the most recent being Guitar Tracks Pro
