There are a number of great free videos: CakeTV YouTube, and some tutorials, as well as written documentation.
There are also commercially available videos and some well-written books that would go a LONG way toward getting you up to speed on X3.
Sonar has a great deal of powerful features - and it is worth investing some time up front to understand what those are, and how to use them.
This forum is also a great resource for information and help with working out problems you run into.
I hope you have a BLAST learning how to get the most out of Sonar X3 - great product.
