One bit of advice is learn the names of things. Learn what a clip is. Learn what an aux track is and so on. Once you learn the terms used to describe features and functions you will be well on your way in understanding Sonar. The manual is ideal for this.
This is my challenge. I am really new to this, I have never done any recording at all. I play the piano - that's it. I'm an IT guy, so the software doesn't intimidate me, but the mountain seems insurmountable. I've been going through the Groove 3 video series on Sonar - it is good for explaining how to do things, but is not much help if you don't know even what you are looking at.
Aux Track? Take Lanes? Master Bus? I haven't the foggiest clue what any of these are. Heck, I don't even know what "comping" means. Its been a very slow process of learning, but I've been amazed at how much I've learned so far. 6 months ago I didn't know what a DAW or Midi was. Now I can record simple audio and VSTi tracks, and even route things back to my modules.
I am having a blast though with all of this. I read the forum religiously, even though it seems to be in a different language to me.
