Ten is a lot! But I will try.. In no order of importance though, kind of a brainstorm on the OP...
10.. Try as fast as possible to get the hang of audio snap, the more you linger on that, the harder it will get.
9.. Learn those preferences, track templates, project templates and fx chains
8.. undock everything, spread your windows out, redock them, get a feel for the workspace, and learn how to use screensets
7.. depending on your version, go one by one through all the tools that Cakewalk Provide.. "The P64 Per Strip, the LP Multiband, the old Sonitus and Cakewalk DX tools, the midi effect..." Learn how to set up your browser structure file.. I forget what its called, but you can set your browser up, so your folders appear in your way.
6. Read the Cakewalk blog, look specifically for a post on Parallel Compression... Practice that, it will help you learn the routing quickly...
5. I thought the Craig Anderton Vids, and the Sonar Power book very cool! The Craig Anderton vids are not for newbies to production.. if you are a production newbie, perhaps best to go with the groove 3 stuff.
4. pay close attention to the types of tracks, and types of clips. you have simple instrument tracks, audio, and midi.. you have audio and midi clips.. you can insert fx directly onto clips.
3. get the hang of freezing synths, bouncing clips, bouncing tracks.. watch your levels as you do it.
2. you might have some crashes in your first month or two.. it could be the program has a random bug here or there, but you will innately learn how to avoid crashes.. a truth with all daws imo...
1.... pay very close attention to the Pro Channel. Sonar is a Daw.. ok.. great. Sonar is also a way to design and shape the sound of an entire production... it may appear very deep, and it is deeper than it appears
