Good Day,
As Dave suggests and perhaps links from within help documentation to instructional or example video's, at least for more major categories of help, (e.g., Audio Snap). I find a lot of the help documentation is somewhat limited to showing a certain feature is available and/or keystrokes to apply/invoke features, but may lack the context of when's or why's it is used and possible results, pro's, con's, perhaps through graphical/animated examples.
Im thinking also some updating and new content to Cakewalk TV/University video's is needed.
What would be nice, as I believe Dave is also suggesting is a complete/official Sonar walk-through course of a small project with both audio/midi content, (with why's, when's and how's) going from, preferences settings, track organization, level setups and recording, mixing and applying various plug-ins, gain, automation, etc., to importing to final stereo/surround track, and possibly a mastering series.
An interactive (live) online course with Craig Anderton, and/or other instructors is something Id definitely be willing to pay for, at a reasonable cost.
That being said I guess there are some Cakewalk and or 3rd-party video courses (e.g., Craig Anderton's new book), and other educational stuff out there on Sonar use that can be purchased, although most also need updating, and/or through online services such as Groove-3.
Cheers
