Guys, the best way to learn this thing is to watch the videos. I watched a video last week and discovered a feature I missed. I like using the standalone version to experiment.
One feature that SONAR users have that no other software users have (I don't have Cubase so someone would have to check it out) is the ability to Drag and Drop from a SONAR track into EZdrummer2. That means that if you have a groove in an existing old project and you don't know what Toontrack library it came from, cut a piece of it out and drop it into the Tap to Find window and use the search to find it. Or you can drop it into the Track creator and search for it through one of the menus.
